Zoological Garden of Amsterdam, don. to lib., xxxiv. PROCEEDINGS or THE ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA. January 3d y 1854. Mr. Lea, Vice-President, in the Chair. Letters were read : From Baron J. W. Yon Miiller, dated Brussels, Nov. 23d, 1853, transmitting the works announced this evening, and also making en- quiries respecting the feasibility of establishing a Zoological Garden in Philadelphia. From Prof. John Le Conte, of Athens, Georgia, acknowledging the receipt of his notice of election as a Correspondent. From Mr. Isaac Lea, dated Philadelphia, Dec. 30th, 1853, returning acknowledgments for his election as a Vice-President of the Academy. A paper was presented for publication in the Proceedings, entitled " On a new Entomostracan of the family Limnadidae, inhabiting the Western waters. By Charles Girard." Beferred to Drs. Leidy, Bridges and Buschenberger. A paper intended for publication in the Proceedings, entitled " On the Ancient Alluvium of the Ohio Biver and its Tributaries, by Alfred T. King, M. D.," was read and referred to Mr. Vaux, Mr. Lea, and Dr. Buschenberger. Mr. Lea exhibited to the Academy a specimen of D'Orbigny's Acostcea giia- d/casa?ia, which he owed to the kindness of that distinguished zoologist, during Mr. Lea's visit to Paris last year. This genus he reminded the members was identical with the Mulleria of Ferussac, as he formerly suggested, and was afterwards satisfied to be the case on seeing the original specimen, described by Ferussac in 1823, which is now in the fine collection of Mr. Delesert in Paris. Mr. Lea stated that although the specimen figured by D'Orbigny had quite a length of stem connecting the young portion of the shell, the Anodonta form, with the mature portion, the Ostrea form, yet this was not necessarily or uni- formly so. In the case of his own specimen this was very different. It hap- pened, as is sometimes the case with the genus Ostrea, a. dead valve was filled up by a subsequent living individual ; and on close examination, there were really dis- covered to exist two specimens of the Anodontiform age ; one on the old single valve at one end, and another on the reverse end appertaining to the living speci- men, having the epidermis on it perfect. Neither of these specimens had a stem, PROCEED. ACAD. NAT. SCI. OF PHILADELPHIA, VOL. VII., NO. I. 1 2 [January; but advanced directly from the form of the Anodonta to that of the Ostrea, leaving the young beaks directly on the edjje of the valves. Mr. Lea thought that the difference of length of the stem, or the absence of it in various specimens arose from the fact of the young individual finding sooner or later something solid to commence the soldering of the under valve to, and then to spread out the area of the valve. On motion, so much of the communication of the Baron Von Milller' as relates to the establishment of a Zoological Garden in this city was referred to the following Committee : Mr. Ord, Mr. Vaux and Dr. Bridges. January 17 th. Vice-President Bridges in the Chair. A letter was read from Capt. John H. Ritchie, U. S. N., dated Phila- delphia, Jan. 10th, 1854, accompanying the donations to the Museum acknowledged at last meeting. Also a letter from J. Pemberton Hutchinson, Esq., dated Philadel- phia, Jan. 16th, 1854, acknowledging the receipt of his notice of elec- tion as a Member. Mr. Conrad presented for publication in the Journal, a Synopsis of the Genera Parapholas and Penicilla ; which was referred to Dr. Ruschen- berger, Dr. Le Conte and Dr. J. A. Meigs. Mr. Lea exhibited a large and beautiful crystal of limpid quartz, cut into facets, which he had obtained in Italy. On leave granted, the Committee, to which was referred Baron Miiller's communication relative to the establishment of a Zoological Gar- den in this city, presented a report adverse to the same, the Committee being firmly impressed with the opinion that the project would not succeed, from " the difficulty of procuring a suitable locality, of convenient access, within the city or its precincts ; the great amount of capital required in the outset of the undertaking, and the precarious nature of the tenure, in this country, of all that depends upon popular favor." The Report was adopted, and a copy directed to be transmitted to Baron Miiller. January %4:ih. Vice-President Bridges in the Chair. Major Le Conte presented a paper, for publication in the Proceedings, entitled " Notice of American Animals formerly known, but now for- gotten or lost." Referred to Mr. Cassin, Dr. Ruschenberger and Dr. Henderson. On leave granted, Mr. Foulke, after stating that it was probable the U. S. Government would fit out shortly an Expedition for the explora- tion of Africa, suggested the appointment of a Committee to urge upon the Government the propriety of having Naturalists attached to the Expedition. Whereupon on motion the following was adopted : Resolved j That a Committee of five members be appointed, whose duty 1854.] 3 it shall be to take such steps as they may deem expedient to recommend to the Government the scientific exploration of Africa. Committee, Dr. Ruschenberger, Dr. Leidy, Mr. Lea ; Prof. Carson and Dr. Hallowell. Junuary 31 si. Vice-President Bridges in the Chair. The Committees to which were referred the following papers, severally reported in favor of their publication in the Proceedings : On a new Entomostracan, of the family LimnadidjE, inhabiting the Western waters. By Charles Girard. LIMNADELLA, n. g. Gen. Char. Eye one. Antennae subequal, provided upon their inferior side with long and plumose setae, whilst on the upper side there are short, slender and simple spines. Two elongated tape-shaped jaws. Eeet in twenty-lour pairs, provided upon their extremities and sides with slender and plumose setae, or hairs. A series of spiny processes along the posterior half of the dorsal line. Post abdominal plate very large. Nutritive system phlebenteric. Observations. This genus diners from Limnadia in being provided with one eye only, instead of two. Also by its antennae, the two pairs of which are similar in structure, whilst in Limnadia one pair is smaller than the other. The post abdominal plate and number of feet will afford other distinguishing charac- ters between Limnadella and Limnadia. From Cyzicus or Estheria it differs, first, by the structure of the shell, which in Estheria resembles that of an Area, whilst, in Limnadella, it is altogether Cyproid in its general aspect. There is a marked difference between these two types in the structure of the an- tennae, the joints of which are provided on their upper part with numerous spines in Limnadella, whilst in Cyzicus there is but one single spine at the anterior edge. The structure of the feet is likewise dissimilar, being furnished with plumose setae in Limnadella. Limnadella Kitet, n. sp. Spec. Char. Shell : elongated, subelliptical, thickest anteriorly ; twice as long as deep ; anterior, inferior, and posterior margins regularly continuous ; upper outline somewhat irregular on account of the beaks being rather promi- nent. Valves uniformly convex. Greatest depth one eight of an inch, greatest length one quarter of an inch. Specimens may occasionally attain to a larger size. Color, deep or light brown, mottled with black. Animal : antennae composed each of twelve or thirteen subequal joints. Twenty-four pairs of feet, the six posterior ones diminishing gradually away so as to render the last three rudimentary. The last of all is inserted upon the last caudal segment but one. There is a broad sub-triangular plate, terminated by two pairs of very large spines, curved upwards; the inferior pair being longer and slenderer than the up- per one. The concave margin of that plate is furnished with a series of quite small spines. On the uppermost part of the post-abdominal plate is inserted a pair of very delicate sword shaped appendages, very difficult to be observed even with a good microscope. Along the posterior half of the back there exists a series of sixteen processes, provided upon their upper and posterior sides with about five or six minute curved spines, the tip of which is bent backwards. The anterior two of these processes are but rudimentary ; the most developed occupy the middle of the series; the posterior ones again diminish gradually as they approximate the post-abdominal plate. Specimens collected at Cincinnati were sent to the Smithsonian Institution by Thomas Kite, of that city. 4 [January, On the Ancient Alluvium of the Ohio River and its Tributaries. By Alfred T. King, M. D., of Greensburgh, Pa. The Ohio River, and all its tributaries which I have examined, are bounded by an ancient alluvial deposit, rising from one to two hundred feet above the present beds of those streams, and extending from half a mile to nearly two miles in width. In the brief description which I design to give of these deposits I shall com- mence with that extensive and remarkable one at the mouth of the Beaver River. This is a beautiful and romantic stream, rising in the northern part of Beaver County, Pennsylvania. It runs nearly south, and empties into the Ohio river about thirty miles below Pittsburgh. At its mouth are two small towns, Rochester on the east and Bridgewater on the west. The town of Beaver, which is the seat of justice of Beaver county, is situated on the hill immediately above and west of Bridgewater, on an alluvial plain, two miles and a half in length, one mile, or nearly so, in width, and one hundred and thirty feet above the bed. of the Ohio, stretching along the northern shore of that river. Although wells have been sunken, in different parts of the town, 128 or 130 feet, which would be about on a level with the bed of the Ohio, still no one has penetrated through this deposite. The strong probability is, therefore, that it extends many feet beneath the present bed of the river. On the opposite side of Beaver river this deposite stretches along the Ohio, about three quarters of a mile. At both ex- tremities it is apparently transferred to the opposite side of the river, in conse- quence of the present curving of the stream, which causes the water to impinge against the base of those lofty hills which everywhere skirt the shores of this picturesque river. Seldom does the Ohio, or any of its numerous and mighty tributaries, flow through the centre of this ancient alluvium, for this deposite is seen every now and then on opposite shores. On the eastern side of Beaver river this deposite is 20 or 30 feet higher than it is at the highest point on Beaver plain, w hich would make it there about 150 or 1 60 feet, above the bed of the Ohio. At the most eastern extremity the hills are com- posed of fine sand and loam, containing fluviatile and terrestrial shells of the genera A?iodo?ita, Unio, Planorbis, Paludina, Limnea and Helix. Nearly the whole of the residue of this deposit at Rochester, Bridgewater and Beaver, is composed of nodules of argillaceous oxide of iron, and of rounded, polished river pebbles, from the size of gravel to the size' of a man's head and upwards. At the town of Rochester, the Pennsylvania and Ohio Railroad Company has made an extensive cut of about eighty feet through this mass of iron nodules and river pebbles. Here it exhibits symptoms of stratification. Commencing at the summit, there is first a thin seam, which composes the surface soil, of sandy loam, then loose pebbles, below which there is a seam of eight or ten feet of conglomerated pebbles cemented together with an oxide of iron. So- firmly bound together are these pebbles, that the workmen, when making the cut, were obliged to blast them, and I am told that they encountered much more difficulty than they ordinarily do in more solid, compact rock. Below this is a seam of ignitable bituminous coal, about one inch and a half in thickness, extending entirely through the cut, and always preserving the same relative position. Below this coal were loose pebbles again, and so on, alternately, from the summit to the base. Doubtless this tendency to stratification in alluvial, as well as in marine de- posites, may be accounted for that streams at different periods transport different materials, but the continuous seams, and vast masses of hydrate of alumina, frequently seen in alluvial bluffs, particularly in those of the Mississippi river, and the pure crystals often seen imbedded in solid sedimentary rocks, clearly indicate the existence of chemical affinity between some of the particles of sediment, in connection with mere mechanical deposition. Beaver river is a small stream, not larger than the Mohawk, but its scenery is exceedingly beautiful. Its calm and placid bosom reflects vividly like a 1854.] 5 mirror the tall mountain cliffs, and the magnificently variegated scenery of the autumnal landscape. The deep gorges and dark precipitous ravines which cut transversely the lofty hills which rise like mountains on each side, and the broad alluvial plains which bound its shores, lined for miles with beautiful towns and villas, where the sound of cheerfulness and the hum of industry are everywhere heard, render the scenery exceeding interesting and picturesque. From the mouth of this river to the town of New Brighton, a distance of about three miles, the alluvium is composed principally of pebbles, resembling those already described. Here it is about one hundred and fifty feet in depth, at the highest point, and about three quarters of a mile wide. From this point to a distance of from ten to fifteen miles above, this deposite is strewed over with immense masses of transported angular rocks, derived from the neighboring hills. These rocks are of all sizes, and, in places, very numerous, strewed about in every direction, and piled upon each other in the most irregular manner. There are several enormous piles of these quartzose rocks, or coal grit, about eight or ten miles from Rochester, lying upon the brow of a hill, which over- looks the river, and more than two hundred feet above its present bed. Some of these masses will weigh thousands of tons. There is one w r hich is probably in situ, which will measure twenty feet in height, and over one hundred feet in circumference, much shattered below, where it is grooved, rounded, and smoothed by the long continued action of running water. This rock presents a singular aspect to the observer who attempts to account for its present form, and its relative position with the river below. It is surrounded by huge but smaller masses of the same character, all exhibiting the same wearing and polishing action of running water, and piled upon each other in the wildest confusion. I descended with Dr. Barker, of Beaver, who kindly accompanied me, this precipitous hill, along a narrow and winding path to the river below. All the way we passed over and around similar piles of rocks, and for miles above this point found a similar condition of things to exist. Most of these rocks are dis- tinctly traceable to their parent hills, still higher up the stream. The enormous size of some of these transported rocks, and the unequivocal evidence of the wearing action of running water upon them, indicate that they were carried by a long continued, turbulent and impetuous stream, which had been, previous to this exhibition of its maddening fury, in a comparatively quiet and placid condition, during which time the subjacent alluvial sediment, before described, was deposited. It may be proper to mention here, that in connection with these angular masses of quartzose grit, I found, not unfrequently, syenitic, granitic, porphyritic, greenstone boulders, &c, &c, which were exceedingly hard, rounded and polished, similar to the more common quartzose pebbles. The largest which I saw connected with the angular rocks w T ould not weigh more than a few hundred pounds. But about three hundred feet above the head of little Beaver creek, a tributary of the Ohio river, and about twelve miles from the locality I am now describing, there are boulders of granite and other primary rocks lying upon the summit of a hill, which will measure thirty feet in circumference. Indeed the hills, which here contain the enormous cannel coal vein of from fourteen to eighteen feet in thickness, are strewed over with boulders of primary rocks, and the diluvial scratches and groovings are visible in places. These hills are, in some places, 300 feet high. At different points along Beaver river, and at heights of more than a hundred feet above its present bed, I observed convincing indications of the grooving, smoothing and polishing action of running water, on the solid sandstones of the adjacent hills. These workings were unquestionably produced by the river when it flowed over this alluvial plain. The same kind of markings I observed in the hills which skirt the shores of the Ohio. About fifteen miles below Pittsburgh, at a place called the Narrows, I observed, at the height of more than a hundred feet above the river, the solid sandstones polished and grooved, as if channelled by the moulding instrument of a joiner, and even pot holes are worn into their sides. 6 [January, Nearly the entire cities of Pittsburgh, Allegheny and Cincinnati are built upon this remarkable deposite. From Pittsburgh to Wilkinsburg, seven miles east, it is seen stretched along the northern shore of the Monongahela river, and nearly two miles in width. To this remarkable locality I will now briefly direct attention. Passing from Greensburgh to Pittsburgh, along the turnpike, it will be observed that the last anticlinal roll of the Allegheny chain of mountains is at Grapeville, four miles west, and the last synclinal trough, which is but imperfectly formed, is about three miles further west. From this point the beautiful undulations which are so characteristic of the Allegheny chain, die away, and the rocks assume nearly a horizontal position. Their horizontality, however, is only appa- rent, for they really rise, at an almost inappreciable angle, westward. From this point to within seven miles of Pittsburgh the general geological and topo- graphical structure of the country remains nearly the same. At the summit of the hill, which overlooks the town of Wilkinsburg, standing upon the limestone which is super-imposed upon the great Pittsburgh seam of coal, the observer beholds, more than a hundred feet beneath him, a beautiful and extensive alluvial plain, bounded on the north by hills, which separate it from the Allegheny river valley, and which contain the coal and limestone to which allusion has just been made, and on the South by the Monongahela river. The whole of this great seam of coal and the incumbent limestone, to the depth of three hundred feet, have been swept away by a process of denudation, and their places partially supplied by an alluvial deposite over one hundred feet in thickness, and about the same height over the present bed of the Monongahela river. As the Pennsylvania Railroad passes over this deposite I shall avail myself of the measurements which are given in one of the last annual reports of the Com- pany. The elevation of the Ohio river at Pittsburgh, above tide, is given at 700 feet. The elevation above tide at Wilkinsburg is 922. There would, there- fore, be a difference of tidal elevation between Pittsburgh and Wilkinsburg of 222 feet. After substracting 22 feet feet for the fall of the river between these two points, we would have 200 feet for the depth of the deposite. If we assume that the shale and limestone upon which this vast deposite re- poses, and which will be presently described, are from 200 to 300 feet beneath the Pittsburgh seam of coal, we will be enabled to form some idea of the enor mous denuding process, by which this river excavated its channel, and after- wards deposited upon its ancient bed, in some places, over two hundred feet of sedimentary matter. This is, of course, only an approximative estimate ; but from all the data which I have been enabled to procure, the average depth may be safely assumed at from one hundred to two hundred feet. In consequence of the great depth of this deposite at Wilkinsburg, I, at one time, conjectured that the Allegheny and Monongahela rivers met, at some antecedent period, and formed the Ohio, either at this point or at East Liberty, which are from five to seven miles East of their present junction. To satisfy myself on this curious point, I crossed the plain at Wilkinsburg, three quarters of a mile, to the base of those lofty hills which separate the two great alluvial valleys, and found that the whole region was composed of river pebbles, sand and loam, with which were mingled fluviatile and terrestrial shells. Near the Frankstown road, which is nearly two miles in a straight line from the Monongahela river, I saw some men excavating a well. They had gone down to the depth of twenty or thirty feet, and had passed through nothing but pure river sand and pebbles, meeting occasionally only with an Anodonta or a Unto. Near this point I crossed the dividing hills, and descended along a narrow path to the road which winds along the bank of the Allegheny river. Here I found this ancient deposite presenting: nearly the same appearances, and of about equal magnitude to the one on the Monongahela side. In the neighborhood of Laurenceville it is of great breadth, and of not less than two hundred feet in hickness. 1854.] 7 The hills which separate these Two ancient alluvial valleys are a continuous chain, and of sufficient altitude to constitute an effectual barrier to the mingling of the waters of these two rivers, at any point nearer than their present con- fluence at the city of Pittsburgh- I observed at Rochester, New Brighton, and at different points along the Monongahela and Allegheny rivers, that this deposite reposes on a dark colored shale, sometimes passing into more compact slate. As I was descending a hill on the Frankstovvn road, near East Liberty, I discovered an old acquaintance, a thin stratum of calcareous rock, on which the shale re- poses, and which in contradistinction to other limestones, belonging to the coal series I have denominated the ^rj^a-limestone. This is a somewhat peculiar rock, characterised by containing a vast number of small bivalve shells, belonging to the genus Atrypa, etc. When long exposed to the atmosphere, its external surface readily disintegrates, and presents a rag- ged and shaly appearance, the surface being covered with small Atrypa and pro- jecting joints of Encrinites. In some localities I have found in this rock the genera Terebratula, Trilobites, Plei/.rotomaria, Productus, Spirifer, Bellerophon, Euomphalus, Ammonite and Orthoceratite. But the joints of Encrinites and the small Atrypa are the charac- teristic fossils, and distinguish it from all other limestones belonging to the car- boniferous series. This limestone, in Westmoreland county, is seldom found more than two or three feet in thickness. But near the Ohio line I found it over ten feet, it being there a very compact and durable rock, well adapted for agri- cultural and other purposes. It is exposed at numerous points in Western Penn- sylvania, and uniformly presents similar lithological and paleontological cha- racters. I mentioned, at the commencement of this paper, that this ancient alluvium was traceable everywhere along the Ohio river and its tributaries which I have examined, and doubtless along those which I have not so closely surveyed. Those tributaries to which my attention has been more particularly directed, are the Beaver, Allegheny, Monongahela, Youghiogeny, Kiskeminitas, Loyalhanna and Conemaugh rivers, etc., etc. But in the brief and necessarily imperfect delinea- tion of these remarkable deposites, which I have attempted to give, I have con- fhied myself to a few localities only, leaving a more extended and minute description for some future period. It is not at all improbable that those high bluffs which bound the vast alluvial valley of the Mississippi river (which is from thirty to fifty miles in width), were deposited at the same period. Also the alluvial terraces on which the city of Cincinnati is built, the highest of which is 120 feet above the level of the Ohio river; and doubtless the natural terraces and ridizes of Lake Erie and Ontario, which were so graphically delineated by Mr. Charles Whittlesey, of Cleveland, in the July No., 1850, of the American Journal of Science. For, in all these localities, fossil teeth and other bones of the mammoth and mastodon have been found imbedded in this deposite. These animals, which were once the lords of the creation, the primates of this lower world, perished and became extinct in that last grand revolution, during which I presume these ancient sedimentary deposites were slowly and gradually elevated to their pre- sent position, and which immediately preceded the advent of man. From the whole of this investigation my mind has been convinced that the relative position of the rivers and this ancient alluvium through which they now pass, or along whose borders their waters deeply flow, has changed since the period of deposition. But when, and in what manner, or by what cause, are questions not so readily answered as proposed. The hypothesis of local oscillations, first proposed many years ago by Sir Charles Lyell, to account for the deposition of the Rhenish loess, will, with slight modifications, I believe, clearly explain all the phenomena connected with this post tertiary formation. Indeed, from the numerous facts upon which this hypothesis is based, it may be regarded as an exceedingly plausible theory, if not a legitimate induction. It has lonj; been ascertained that various parts of the earth's surface are now, and perhaps ever have been, undergoing slow and gradual oscillatory movements. 8 [January, Parts of Sweden, Norway, and the shores of the gulf of Bothnia, have been long gradually rising. Also extensive regions of South America have been undergoing a slow but gradual upheaval, during a period of many centuries. On the other hand, the gradual sinking of the coast of Greenland, for the space of more than six hundred miles, during the last 400 years, has been more incon- trovertibly established by actual markings and critical examinations made by the most astute minds. Large portions of the earth's surface have been suddenly upheaved, whilst others have as suddenly subsided. The whole coast of Chili was suddenly elevated several feet by the earth- quake of 1822, producing terrible commotion in the sea, and sending vast waves over the ocean, which doubtless transported huge masses of rocks many miles from the shore. In 1611, an earthquake sank the town of New Madrid, on the Mississippi river, several feet beneath the waters, the vibrations of which continued three months. Many other facts of an analogous character might be adduced, but these are sufficient to show that various parts of the crust of the earth are now under- going oscillations, and that it is not at all improbable that the hydrographical basin of the Ohio may have undergone, at some remote period, similar move- ments. First we may suppose that there was a gradual subsidence during a period, perhaps, of many centuries, of the whole hydrographical basins of the Ohio and Mississippi rivers, and even extending beyond che limits of their tributary streams. This depression of the land would necessarily lessen the fall of the waters into the Gulf of Mexico, and increase the alluvial deposite. After a cer- tain indefinite period we can readily suppose that this process of subsidence was reversed, and the whole as gradually upheaved, until the rocks were brought to their present altitude, when the oscillation ceased. During this slow upward movement the waters would necessarily cut their channels through the alluvial deposite, which had been thrown down during the process of subsidence. At the commencement of this upward movement we may suppose a sudden upheaval to have occurred in Beaver county, somewhat analogous to that on the coast of Chili, in 1822, which would produce such commotion and recoil of the waters in Beaver river as to cause them to impinge, with terrific force, against the projecting rocks of the adjacent hills, rive them asunder, and pile thein as they are now found, over its ancient alluvial bed. Afterwards, the process of elevation may have been as gradual as that of the shores of the Gulf of Bothnia, which amounts only to two or three feet in a century. In corroboration of this view I may mention, that although the rocks are nearly horizontal, yet the hills which skirt the shores of this beautiful stream are often seen cracked from the base to the summit, and the strata, in places, much disturbed. Also, the dark, yawning gorges, and broad and deep ravines, cutting entirely through the hills, indicate, I think, that the rocks here of the ancient coal measures have undergone great disturbance since the period of their original deposition. Notice of American Animals, formerly known, but now forgotten or lost. By John Le Co.nte. The writers of the last century have left us descriptions of several animals which modern research has not since been able to detect. In looking over the works of these authors, who favored the world with their knowledge so long ago, it necessarily happens that we find their descriptions more or less imper- fect, either from the insufficient manner in which they were made, or from that brevity of expression which was then fashionable in natural science. Hence 1854.] 9 has arisen much confusion and indecision. I have selected from these writers of a former age, the following animals which appear to have heen then well known, but are now forgotten or overlooked ; I beg leave to call the attention of natur- alists to this subject, with the hope that they may be all found and accurately described, or else struck out from the number of those enumerated among the productions of America. Felis rufa, or Bay Cat of Pennant, Arc. Zool., vol i. p. 51. With yellow irids, ears erect, tufted with black long hair; color of the head, body, and outside of the legs and thighs a bright bay, obscurely marked with dusky spots; the forehead marked with black stripes, from the head to the nose; cheeks white, varied with three or four incurvated lines of black; the under and upper lip, belly, and inside of the legs and thighs white, the inside of the upper part of the fore legs crossed with two black bars ; the tail short, upper part marked with dusky bars and near the end with one of black, the underside white; fur short and smooth ; twice the size of a common cat, (that is 27 inches long,) said to come from the interior of New York: probably erroneous. Described by Mr. Pennant from the living animal. The common wild cat of our country, found in all the northern, southern, and western states, has in latter years been confounded with this species ; I think, however, they cannot but be distinct. Mr. Pennant, the best naturalist that England has ever produced, could never have confounded two animals so dis- similar. It is true, in describing one, he had before him the living animal, in the other a dried skin, but of the last, he could examine hundreds. He certainly could not have mistaken the indistinct brownish grey of the one for bright bay, nor could the last color have faded into the other. The common wild cat, however, never should have been called Felis rufa, even if it was identical with Pennant's animal, as Ray had described it in his Synopsis Methodica Animalium, p. 169, as Catus montanus. If these two ani- mals are the same, why has the name given so long even before the birth of Pennant, been discarded, in defiance of the rule of priority in nomenclature ; when it was last described, it was easy to restore the name of montanus. A just regard for the name of Ray, if nothing else, surely demanded this. A description follows of the Felis montana, as I knew it in Georgia, made from numerous specimens either living or recently killed, including probably every variation to which the animal is liable. Felis montana. Mountain Cat, Pennant, Arc. Zool., vol. i, p. 51. Catus mon- tanus, Ray, Synops. Method. Animalium. Above, hair mixed dusky, and pale brown, top of the head brown striped lon- gitudinally with dusky, cheeks with dark brown, back with dusky ; the last sometimes wanting. Irids yellow, ears black, upright, and slightly pencilled, especially during the winter; with a broad, transverse, cinereous bar. Cheeks on each side with a large semicircular tuft of long hair. Legs spotted with dark brown, sides most frequently obscurely spotted with the same, sometimes, how- ever, not spotted; chin and throat white, with a black stripe on each side, form- ing an angle ; sometimes these stripes are wanting, or very faintly marked in pale brown. Belly, inside of the thighs, and hind part of the fore legs whitish, spotted with black. Tail, above, generally very faintly annulate with brown; these rings often disappear; tip black, beneath white, which color appears on the upper part at the tip, whenever the hair is in any way disturbed. Feet beneath dusky or dark brown. Mean length of 12 specimens 31 inches, tail 6. I have given the foregoing very full description, that it may be compared with the preceding. Most of the marks which are common to the two, belong to al- most every species of the genus Felis. I add two obscure species, of which but little is known. I am not willing to pronounce them distinct from each other or from the montana, without farther examination. The first was seen in Califor- nia by my son, and the description and measurements were made by him ; the other is extracted from Lewis and Clarke's travels. 10 [January, Californian Wild Cat : Above, mottled white, black, and fuscous, lighter on the sides, which are slightly barred; beneath, white; legs fuscous, with black bars, much more dis- tinct on the anterior ones, which are anteriorly white. Ears large, rounded, black, with a white spot connected with the mastoid part, tip with a short tuft. Tail short, blunt, barred with darker, tip black with an extreme white point. Length 31 inches, tail 6, head 4.5, height 1.5. Lewis and darkens Wild Cat : Larger than the wild cat of the United States; color of the back, neck, and sides reddish brown, irregularly varied, with small spots of dark brown, tail two inches long and nearly white, except the extremity which is black; it terminates abruptly, as if amputated. Belly white, variegated with small black spots, legs of the same color as the sides. The back is marked transversely with black stripes; ears black, on the outer side covered with short fine hair, except at the upper part, where it is furnished with a parcel of fine, straight, black hair three- fourths of an inch long. The hair of the animal is long and fine. This animal was called by Rafinesque, Felis fasciata. I have declined adopt- ing his name, as he never saw it, and was too much in the habit of describing things by hearsay, with as much confidence as if he had himself procured them, and had them lying before him. A drawing or an engraving was sufficient for him to make a new genus from, as was often the case, I am sorry to say, with authors of more credit. Both Charlevoix and Dupratz, mention a species of Felis in Louisiana, which appears not to have been lately seen ; they call it Pichoux; the following is a description of it Pichoux : Upper part of the head, neck, back, sides, shoulders, and thighs bright tawny, face striped downwards with black, shoulders and body marked with stripes and large oblong black spots, the legs with small spots, breast and inner side of the legs and thighs whitish, spotted with black ; tail long, marked with black, taw- ny, and grey. Size of a common cat, (about 18 inches). Does not appear to be the Felis pardalis, from its smaller size, and probably different markings, besides being in some of the under parts white. If this ani- mal is no longer found in Louisiana, it is highly probable that it may be met with in Texas or New Mexico. Animals at one time extremely common in any particular country, will suddenly leave it without any visible cause. As an in- stance of this : previous to the year 1820, no bird was more common in that part Georgia where I resided, than the Conurus Carolinensis or Parakeet. They would pass through the air in flocks of from 50 to 100. They suddenly all disappeared, and for more than thirty years, not one has been seen where they were so abun- dant. Travellers through Texas and New Mexico, would do well to look for this beautiful species of cat. The Chat sauvage, described by Dupratz, vol. ii., p. 93, is an animal well worth enquiring about. He thus describes it : Chat sauvage : He says that it does not feed on animal substances, but on fruits, bread, and other vegetables. It seems that it w r as easily and often tamed. It is gentle and frolicsome, and not more than 8 or 10 inches high and about 15 long. The head like that of a fox : when tamed the color is grey ; when wild, red : its paws have long toes and short claws ; it has improperly been called a cat, as it has nothing of the cat about it but its activity, and bears a greater resemblance to the marmot. 1854.] 11 Silvery Fox, of Louisiana, Penn. I. c, p. 48. With a fine and thick coat of a deep brown color, overspread with long silvery- hairs of a most elegant appearance. They differ from most other American species in their habit of burrowing. The description is borrowed from Dupratz, vol. ii., p. 92. This can hardly be the Canis velox. Pennant in Supp. to Arctic Zoology, p. 52, mentions a whitish grey fox, no larger than a hare, common among the Archithinne Indians, 4000 skins of which have been brought in one year to the British factories. The Comanche Dog : Common among the Comanche Indians. Naked, except a few stiff hairs about the mouth. This dog is mentioned by Clavigero, vol. i., p. 56, as an inhabitant of Mexico, called by the natives Holoitzuicintli. It is remarkable that though some of these dogs have been brought within the United States, we have no description of them : they are quite large, being upwards of two feet high, and used by the natives for hunting. Here is an instance of the absurdity of those writers who state, that climate has an influence in altering the appearance of animals ; thus they tell you that the so-called Turkish dog, which is hairless, has been made so by its progenitors living for numerous generations in a warm climate ; now here we see an animal equally naked, which inhabits the moun- tains and cold steppes of the south-west. Of a similar character is the assertion that sheep lose their wool in the Southern States, and in the West India Islands. The Water Rat of Pennant, 1. c, p. 130. With small eyes, ears covered with fur, teeth yellow, body covered with long black hair, mixed with a few of a rust color, belly of a deep grey. A Mouse of Louisiana : Mentioned by Dupratz. Not larger than Mus musculus, of a very bright bay. These are all the mammals which I can collect, as worthy of being called im- perfectly known, or rather lost to modern naturalists. I now proceed to consider the Birds. Vultur sacra : Bartram's Travels, p. 150. The head and neck are bare of feathers nearly down to the stomach, where the feathers begin to cover the skin, and soon become long and of a soft texture, forming a ruff or tippet, in which the bird, by contracting his neck, can hide that as well as the head ; the bare skin on the neck appears loose and wrinkled, which is of a very deep bright yellow color, intermixed with coral red as it approaches the yellow of the sides and fore part. The crown of the head is red; there are lobed lappets of a reddish orange color, which lie on the base of the upper man- dible. But what is singular is, a large portion of the stomach hangs down on the breast of the bird, in likeness of a sack or half wallet, and seems to be a dupli- cature of the craw, which is naked and of a reddish flesh color, this is partly concealed by the feathers of the breast, unless when it is loaded with food, and then it appears prominent. The plumage of the bird is generally white or cream colored, except the quill feathers of the wings and two or three rows of the co- verts, which are of a beautiful dark brown; the tail which is large and white, is tipt with this dark brown or black, the legs and feet are of a clear white ; the irids golden ; the pupil black. The tail was used by the Seminoles as a war standard. Dupratz, vol. ii., p. 109, mentions this bird under the name of White Eagle, and says that the Indians in whose neighborhood he lived, the Natchez, used the feathers for adorning their pipe of peace. Ferruginous Woodpecker : Pennant, 1. C, p. 271. With a dusky bill, the crown and pendant crest of a pale yellow ; a crimson bar extends from the mouth along the lower part of the cheek. The cheeks, 12 [January, back, and coverts of the wings are of a'deep ferruginous color, lower part of the back of a pale yellow ; primaries ferruginous, barred on their inner webs with black. Sent from South Carolina to Mr. Pennant, by Dr. Garden ; therefore there can be no doubt of its having been obtained near Charleston, although no one has ever seen it since. The high character of both these gentlemen forbids us to suppose that there was any deception on either side, either in sending the animal to Europe, or in its habitat. The Florida Pheasant : Mentioned at page 20 of Stork's introduction to John Bartram's Journal of Travels in East Florida. I have had described to me a bird, which must have been this, as inhabiting the hummocks on the banks of St. John's River, but I never had the good fortune to meet with it. Norton Sound Bustard, Penn. vol. iii., p. 321. A Captain Rich informed Mr. Pennant, that at Norton's Sound, in latitude 64 30', he had seen great flocks of a large bird which were very shy, ran very fast, and for a considerable way before they took wing, so that he could never get one shot. Black Ibis, Bartram's Travels, p. 148. Black on the upper side, breast and belly white, legs and beak as white as snow. Size of Ibis alba. Red-billed Heron, Pennant, Supp., p. 65. With a red bill. Irids yellow, legs green, plumage white. There are many of the smaller birds of America described by Pennant, that I am convinced are not now known, and many more that have lately been de- scribed as new species, that were well known to the English naturalist. Not being, however, sufficiently acquainted with the ornithology of our country, I cannot, without devoting too much time to the subject, determine which they are. It has all along been the custom with American naturalists, entirely to neglect everything that this illustrious man and elegant scholar has written on the subject of our animals; but it would be a labor well repaid by the thanks of every lover of science, if any one would go over his Arctic Zoology, and give us the scientific names of every thing which he has described. There remain only a few reptiles to be added to this list : there can be no dif- ficulty in obtaining them if they really exist, and I cannot see how any one can doubt of their existence. A very little attention on the part of persons living where they are said to be found, would soon make us acquainted with them. Trionyx, of Bartram. Travels, p. 177. They are flat and thin, two and a half feet in length, and eighteen inches in breadth across the back ; in form resembling the sea tortoise, the whole back shell except the vertebrae or ridge, which is not at all prominent, and ribs on each side, is soft and cartilaginous, and easily reduced to a jelly when boiled ; the an- terior and posterior extremities of the back shell appear to be embossed with round horny warts or tubercles ; the belly or nether shell is but small and car- tilaginous, except a narrow cross bar connecting it at each end with the back shell, which is hard and osseous ; the head is large and clubbed, of nearly an oval form, the upper mandible is however, protruded forward and truncated, somewhat resembling a swine's snout, at the extreme end of which the nostrils are placed ; on each side of the base or root of this proboscis are the eyes, which are large. The upper beak is hooked and sharp like a hawk's bill ; the lips and corners of the mouth large, tumid, wrinkled and barbed with long pointed warts which can be projected or contracted at pleasure, which gives the creature a frightful and disagreeable countenance. Inhabits St. John's river, Florida. It is a remarkable circumstance, that although this tortoise is found as it were at our very doors, no one has ever seen it since the venerable author of the pre- 1854.] 13 ceding description noticed it in his travels. There can be no doubt of its exist- ence in St. John's river of Florida, and that it can be obtained at any time. Although it is represented in the figure attached to the description with five claws on all the feet, this does not detract from the truth of the account. If this be an error, I attribute it to his not having made a complete drawing of it at the time when he first saw it, and afterwards having finished it from memory ; from this may have resulted the error, if there is one. Although I do not see any more difficulty in a Trionyx having claws on all his toes, than in a Cistudo having three claws when it has five toes j in this case there is a subtraction, in the other an addition. It has been said that this wa3 an incorrect and exaggerated figure of the Trionyx spiniferus (spinifer) of Lesueur. Nothing can be more absurd than this assertion. Lesueur's species has on the front part of the cara- pace a series of small pointed warts not easily discoverable, while Bartram's animal has larger extensible and contractile tubercles on the head and neck. I remember when it was much the custom to ridicule Mr. Bartram, and to doubt the truth of many of his relations. For my own part I must say, that having travelled in his track I have tested his accuracy, and can bear testimony to the absolute correctness of all his statements. I travelled through Florida before it was overrun by its present inhabitants, and found every thing exactly as he re- ported it to be when he was there, even to the locality of small and insignificant plants. Mr. Bartram was a man of unimpeached integrity and veracity, of primeval simplicity of manners and honesty unsuited to these times, when such virtues are not appreciated. Apalone hudsonica, Rafinesque, Annals of Nature, p. 3. Upper shell rounded-elliptical, fiat, entire, soft, with a small anterior keel, yellowish with brown spots, and a circular black line near the margin. Two long oculated spots before and behind the eyes. Nose proboscidal; jaws with- out a bill. Lower shell anterior. Body denudated behind. Tail obtuse, mu- cronate, shorter than the shell. Five palmated toes to all the feet, with small claws. Length 2 to 6 inches. Found in the Hudson river between the falls of Hadley, Glen, and Baker, and further up to the source. Called Mud Turtle. Although this description was published long ago by Rafinesque, no one, that I know of, has ever thought fit to look for the animal. Now, although Rafin- esque was certainly insane and apt to see and describe things w r hich had no real existence, yet when his descriptions appear full and complete, and his localities accurately specified, it certainly is worth while to look for the objects he pro- fesses to have seen. Why do not some of our young naturalists take such things in hand ? Advancing age forbids me. The slender Lizard, Penn. Supp., p. 86. About eight inches long, as slender as a crow-quill; head small, tail blunt and of equal thickness ; body marked from head to tail with lines of pale brown and black, belly lead color ; top of the nose and tail white. Salamandra. 1 once saw, and indeed had in my possession, a Triton or Salamandra, which was sent from New Orleans, of which the following is a short description. I add it in this place because it was a most extraordinary animal. Dusky, speckled with yellowish white, and inclining to blown on the belly ; everywhere except on the belly and tail covered with small warts, so as to re- semble shagreen; tail blunt, with a narrow fin wrinkled longitudinally and trans- versely so as to appear striated and articulated. Length 5 in. .75. The preceding are all the animals which I can find that have once been more or less particularly described, but of which at present no one knows anything. I might have added to the list many that have been described by Rafinesque, but the most of them appear in their coloring, as well as in other characteristics, so opposed to everything known of congeneric species, as to render it extremely probable that the author was laboring under some delusion when he published 14 [January, them. It is well known that he was in the habit of describing things which he never saw, and in his eagerness to claim a priority in discovery, to describe the same object two or three times over under different names. It is to be hoped that the reading of these few pages will turn the attention of naturalists in the Southern and Western States to the investigation of the few species pointed out as forgotten or lost, and that we will not remain long with- out knowing whether they have a real existence. The Committee on Mr. Conrad's " Synopsis of the Genera Paraph ol as and Penicilla " reported in favor of publication in the Journal. A report was read from a Committee appointed at the meeting of 3d inst., to inquire into the expediency of having an Address delivered be- fore the Society at its Anniversary on the 21st of March next, and to nominate a suitable person to prepare such an Address, recommending the same, and nominating Win.

P. Gibbons. Dr. Gibbons proposes the generic name Holconote, and for one species H. Agassizi. For another species the California Academy proposed H. Gibbonsensis. Dr. Le Conte presented a paper for publication in the Proceedings, entitled " Descriptions of some Coleoptera from Oregon, collected by Dr. J. G. Cooper, &c, &c. j" and also a second paper entitled " Synopsis of the (Edemeridag of the United States ;" both of which were referred to Dr. Zantzinger, Prof. Haldeman and Mr. Cooke. 16 [February, February 2th. Vice-President Bridges in the Chair. The Committee on Dr. Le Conte's papers read at the meeting of 21st inst., reported in favor of publication. Descriptions of some new Coleoptera from Oregon, collected by Dr. J. G. Cooper of the North Pacific R. R. Expedition, tinder Gov. J. J. Stevens. By John L. LeConte, M. D. The following species were contained in a collection recently made by Dr. Cooper, and kindly placed in my hands by Prof. Baird. The total number of species collected was nearly 70; among which are specimens of Omus De j e a n ii and Audouini. Among the described species, not before noticed in our territory, is Ancylochira L a n g i i, (Buprestis Langii, Mann.) and among species also found on the Atlantic side of the continent, Haplochile p y g- maea, Lee {Morio pyg. Dej.), Clytus undulatus Say, Monohammus s c u- t e 1 a r i s Say, Hispa v i 1 1 a t a Fabr., Eumolpus a u r a t u s Fabr., Galleruca canadensis Kirby. This indicates, that notwithstanding the extensive collections which have been made both in California and Russian America, the Coleoptera of Western America are still comparatively unknown, and that consequently even small .collectious made by travellers, who have but little time to devote to science, will possess very great scientific value. Cicindela, n. sp. The thorax of the specimen has been destroyed, and the species can therefore be made known only approximately, until the native species of the genus have been properly arranged in systematic order. The species in question seems most closely allied to C. longilabris Say, which it resembles exactly in its markings, but the elytra are less deeply punctured, and of a dull greenish bronze color; the apex is broadly rounded and finely serrate; the suture is armed with a minute spine. The labrum is not longer than is usual in the species of the genus, and entirely resembles in form C. 12-guttata, having only one distinct tooth at the middle; the palpi (of the female) are black; the sculp- ture of the head precisely as C. 12-guttata. Platynus, a species resembling P. obsoletus (Feronia obs. Say,) in every re- spect except that the elytra are somewhat wider. I have not yet investigated this genus sufficiently to pronounce upon the value of such a difference. Carabus oregonensis, cyaneo-niger thorace fere opaco, latitudine vix breviore minus convexo dense intricato-rugoso, antice posticeque angustato, lateribus rotundatis, angulis posticis modice productis, apice rotundatis, lateribus pone medium subreflexis, elytris thorace fere duplo latioribus subtiliter striolato- punctatis, foveis minus profundis serie triplici impressis. Long. -85. One male found at Prairie Paso. This species is closely related to C. taedatus Fabr. (also found by Dr. Cooper,) but the thorax is proportionally smaller and narrower and much more densely and finely rugose ; the rugosities of the head are also smaller, and the impressions less deep ; the striae of the elytra and the impressed foveas are all less marked. Calosoma aenescens, nigroaeneus, crassiusculus, thorace latitudine plus duplo breviore, subtilius dense intricato-rugoso, basi utrinque late foveato, lateri- bus latius rotundatis pone medium modice reflexis angulis posticis paulo productis rotundatis, elytris thorace latioribus seriatim punctatis, foveisque aeneis triplici serie impressis, interstitiis catenatim paulo elevatis, tibiis intermediis rectis. Long. .8- Both sexes, found at Fort Vancouver. This species is very'different from C. tepidum and calidum by the thorax being less rounded on the sides and the pos- terior angles being distinctly prolonged. To Callisthenes it approaches by its form, but the wings are large, and the outer points of the antennae are entirely pubescent. The spaces between the foveas of the elytra are also quite distinctly elevated. 1854.] 17 Ancylochira a d i e c t a, supra splendide viridiaenea, dense punctata, crassius- cula, thorace latitudine fere triplo breviore, antrorsum anguslato, lateribus late rotundatis cuprascentibus, late canaliculate-, elytris lateribus late, sutura an- guste cupreis, costis utrinque 4, scutellarique cum sutura confluente elevatis laevibus nitidis, costa altera subsuturali fere integra adiecta, interstitiis dense punctatis, apice subemarginata. Long. *6, lat '25. One specimen found between Fort Vancouver and Yokolt Plain, in July. This species belongs to a group of species having the form of A. aurulenta and striata, but differs from all the others known to me by having obsolete costae in the in- tervals between the four ordinary costae, and by having an additional costa ex- tending nearly from the apex to the base between the elevated suture and the normal first dorsal costa. The head is entirely free from hair, and is uniformly punctured ; the under surface of the body is bright coppery, tinged with green, moderately punctured; the prosternum is broadly impressed between the coxae, and is not hairy. Ancylochira lauta, supra splendide viridi-aurea, dense punctata, fronte non concava fere glabra, thorace latitudine plus duplo breviore, antrorsum angustato, lateribus late rotundatis cuprascentibus, late canaliculato, elytris lateribus late, sutura anguste cupreis, costis 4, alteraque scutellari cum sutura confluente nitidis laevibus elevatis, interstitiis dense granulato-punctatis, apice vix truncata. Long. -58 '75. Abundant in Oregon, whence it has been brought by Dr. Townsend, Capt. Wilkes' Expedition, Col. M/Call and Dr. Cooper. Resembles the brilliant variety of A. striata, but is distinguished by its more robust form, and by the costae of the elytra being impunctured. A variety occurs in which the elytra have each a broad blue vitta, extending from the first to the third costa. The body be- neath is coppery, somewhat hairy, and the antepectus is impressed between the coxae ; the front has a narrow somewhat smooth medial line. Ancylochira radians, supra splendide'viridi-aurea, dense punctata fronte concava, longe albo-pilosa, thorace latitudine vix duplo breviore, antrorsum an- gustato, lateribus late subrotundatis cuprascentibus, disco late canaliculato, elytris sutura margineque cupreis, costisque quatuor alteraque scutellari cum sutura confluente nitidis elevatis laevibus, interstitiis dense granulato-punctatis, apice subtruncata. Long. *6, lat. -23. One specimen found at Fort Vancouver. It is with some hesitation that I venture to describe this species as distinct : its general form is narrower than A. lauta, and is very much that of A. striata: from the latter it differs by the somewhat concave and pilose front. The pectus is as in the other species, but is densely clothed with long white hair. The under surface is coppery golden, more densely punctured than in the preceding. Ancylochira pl'acida, viridi-aurea, cupreo-tincta, confertissime punctata, thorace latitudine fere duplo breviore, antrorsum subangustato, lateribus late ro- tundatis, postice transversim impresso, elytris vitta cuprea utrinque ornatis, striis punctatis haud distincte impressis, apice conjunctim rotundatis, Long. 29. Collected by the late J. K. Townsend, in Oregon, and given me by Mr. Will- cox, as Phcenops placida of the Berlin museum. The form of body is more cylindrical than in the other species known to me; the pectus is not canaliculate, and the prolongation of the sternum is broader and more obtuse than in A. decora, or the other species with which I have compared it. The insect, though differing from Ancylochira in having the scutel slightly pointed behind, ap- proaches much nearer to that genus than to Phaenops, and until a revision is made of the genera of our native Buprestidae on more natural characters than have been hitherto employed in their study, should be suffered to remain where I have placed it. Ellycbnia facula, elongato-elliptica, atra tenuiter pubescens, thorace latitu- dine vix breviore, disco convexiusculo, lateribus et apice concavis reflexis punctatis, macula submarginali lunata rosea ornato, elytris dense punctulatis linea unica dorsali obsoleta utrinque notata. Long. *52. One specimen, Prairie Paso, differs from E. corrusca by its less dilated 2 18 [February. form, and longer thorax, and by Ike presence of only one elevated line on each elytron. Lytta Cooperi, atra, capite thoraceque laete fulvis, nitidis laevigatis, illo basi subemarginato, ante oculos nigro, hoc pentagonali, latitudine breviore, an- gulis lateralibus acatis, dorso deplanato, elytris lineis elevatis grosse reticulatis ; antennis extus incrassatis, articulis rotundatis, tibiis posticis calcari externo lon- giore dilatato. Lous- - 73. Wenass river, to Fort Colville. It affords me great pleasure to dedicate this fine species to Dr. Cooper, to whose taste for natural history we are indebted for the present interesting collection. This species belongs to group (A b) of my synopsis of Meloides, (Proc. Acad. 6, 334,) near L. vulnerata, but is very distinct by the reticulated elytra. Ditylus gracilis, elongatus ater, tenuiter pubescens, thorace latitudine lon- giore, obovato postice angustato, lateribus antice rotundatis, dense punctulato, late profunde canaliculato, disco utrinque ante medium subfoveato, elytrts subti- liter granulato-punctatis, lineis 4 distinctis subelevatis. Long. 63. One specimen found between Fort Vancouver and Yokolt Plain, in July. Very different from the two species mentioned on p. 20, by the more slender form and elongate thorax; the dorsal channel is dilated and bifurcated towards the apex and base of the thorax. Phymatodes aeneus, osneo-piceus, parcius pubescens, thorace latitudine bre- viore, rotundato punctulato, antice posticeque marginato, elytris thorace paulo latioribus, nitidissimis, parce punctatis, femoribus valde clavatis, antennarum basi rufescente. Long. *3. One specimen found betw r een Fort Vancouver and Yokolt Plain. Somewhat resembles in appearance P. sereus. Asemum a s p e r u m, nigro-piceum, tenuiter pubescens, capite scabro-punctato, oculis magnis valde emarginatis, thorace latitudine breviore rotundato, punctato, medio late excavato, versus latera punctis elevatis exasperato, elytris subtiliter scabris, lineis duabus obsoletis vix distinctis. Long. *7 *9. Prairie Paso, July to August. This fine species seems intermediate between Criocephalus and Asemum ; the eyes, although nearly as large as in the former genus, are deeply emarginate; the antennae are hardly half as long as the body, and pubescent. The discoidal excavation of the thorax does not extend much in front of the middle. Crossidius ? h i r t i p e s, ater, thorace confertim punctato, latitudine breviore, lateribus obtuse armatis, basi marginata, disco utrinque pone medium subfo- veato, elytris confertim subtilius punctatis, fulvis, sutura basique nigro-margi- natis, abdomine sanguineo, basi obscuro ; subtus parcius longe pilosus, tibiis intus dense pilosis. Long. *5 One specimen, Wenass river to Fort Colville. The palpi and antennae are destroyed: it is possible that this should form a separate genus, but the man- dibles are emarginate at tip as in Crossidius, from which it seems to differ in having the thorax obtusely armed at the sides, as in Purpuricenus. The upper surface may have been hairy, as in C. testaceus, but the hair is now en- tirely removed. The elevated lines of the elytra are hardly visible. Toxotus flavolineatus, niger, flavo-pubescens, thorace antice posticeque valde constricto, nitido parcius punctulato, canaliculato, lateribus tuberculo magno acuto armatis elytris a basi angustatis, thorace duplo latioribus dense punctu- latis et rugosis, margine a basi fere ad apicem vittaque dorsali postice evanes- cente antice abbreviata utrinque ornatis, apice intus subtruncata. Long. 1*0. One specimen, Fort Vancouver to Yokolt Plain. On each side of the yellow dorsal vitta is a distinct elevated line. Strangalia vitiosa, nigra, flavo-pubescens, capite rufo-variegato, thorace confertim punctato, latitudine breviore antrorsum angustato, lateribus subangu- latis basique subito depressa testaceis, disco nigro, subcanaliculato, postice utrin- que oblique impresso, elytris punctatis fiavis, a basi angustatis, macula laterali 1854.] VJ ad medium apiceque late nigris, ilia oblique intus emarginata, pedibus testaceis femoribus tibiisque posticis ad apicem genubus tarsisque nigris, antennis pallido annulatis. Long. -7. Two specimens, one having the third joint of the antennae black, the other, having it pale at the base, like the following joints : Fort Vancouver and Prairie Paso. This species resembles very closely S. obliterata, but the thorax is shorter and more dilated posteriorly; the impressions are much stronger, and the disc is separated from the base by a sudden declivity ; the basal margin is also yellow, and there is no trace of the two elytral spots before the middle ; the apex of the elytra is not at all rufous. In the description of S. obliterata (Journ. Acad. Nat. Sc. 2d ser. 1, 328) the testaceous sides of the thorax and the annulate antennas are not mentioned ; they were overlooked on account of the dark color of the specimen from which the description was made. Plectrura product a, nigro-picea, parce griseo pubescens, guttulis flavo-pu- bescentibus parce adspersa, confertim rugose punctata, thorace callo dorsali parvo, elytris callis subquinque-seriatis nitidis parce ornatis, apice non crenula- tis, singulatim longe acuminatis, antennis annulatis. Long. 5. One specimen, Fort Vancouver. This species does not agree with the des- cription of P. sprnicauda Mann. (Bull. Mosc. 1852, 366). The thorax has a strong: lateral spine, with some smaller ones around it, as required in the generic description, but the tips of the elytra are not crenulate; the smooth tubercles form five series, of which only the outer one is entire; the others are imperfect, containing only three or four tubercles each ; the sutural one is indistinct, the second ends just behind the middle ; the third and fourth are abbreviated at each end, commencing about one-third from the base, and ending at one-fifth from the apex ; the scutellum and a little thoracic line anterior to it are more densely pubescent, with yellow hair, than any other portions. Tetraopes oregonensis, niger, capite thorace elytrisque coccineis (pallide pubescens ?) thorace nigro-4-punctato, disco medio subito elevato, antice pos- ticeque valde constricto, lateribus subito valde dilatatis, parcius punctate elytris parce punctatis puncto humerali, duobus ante medium, altero utrinque pone medium, scutelloque nigris, pedibus antennarumque articulo lmo coccineis. tarsis, genubus, tibiisque posticis nigris. Long. -55. Wenass River to Fort Colville. This species has the form of T.femora- t us Lee, but the thorax is still more dilated on the sides. From T. basalis (the only other species known to me in which the base of the antennae is red) it is easily known by the sudden elevation of the disc of the thorax. The pubescence has been removed by the alcohol, and I am therefore uncertain whecher the antennae are annulated. The black spots of the elytra are in the usual position, but are very small, and, with the exception of the humeral one, disappear entirely in many specimens. Coccinella subversa, hemispherica nigra, capite ante oculos albo (ore, cly- peoque feminae nigris) thorace subtiliter punctulato, lateribus rotundatis, macula antica ad angulos quadrata, apiceque albis, elytris distincte at subtiliter punctu- latis scutello nigro, et praecipue macula obliqua ad medium nigra notatis. Long. '2. This species resembles closely C. c a lifo r n i c a, but is smaller, and the elytra are much more distinctly punctulate. Hippodamia mo est a, rufescente-nigra, nitida, dense subtiliter pur,ctulata, macula frontali rhomboidea, thoracis margine laterali antice posticeque latiore, linea media ante medium, guttisque dorsalibus duabus albis, elytris thorace lati- oribus macula laterali triangulari ad quadratem posticum alba ornatis. Long. 3. Prairie Paso. The ungues are acutely toothed, as in most species of the genus ; the white triangular spot of the elytra is between one-fourth and one-fifth from the apex, and is somewhat dilated along the margin in one specimen. Necrophorus p o 1 1 i n c t o r, niger, thorace ovali, transverso, marginibus late depressis, disco tenuiter canaliculato, fortius transversim impresso, elytris par- 20 [FEBRUARY^ cius punctatis macula ad medium laterali in epipleuram extenso, aJteraque parva lunata anteapicali rubris, pectore flavo-pubescente, abdomine breviter griseo- ciliato, tibiis posticis rectis. Long. -58. Fort Vancouver to Yokolt Plain. Of the species found in the Atlantic States, this approaches most nearly toN. sexpustulatus; the thorax is almost pre- cisely as in that species, but is more profoundly impressed j the margin is punc- tured, the disc in one specimen is smooth, in the other obsoletely punctulate^ The antennae are entirely black. Necrophorus confossor, niger, thorace ovali, transverso marginibus punc- tatis late depressis, disco parce punctulato canaliculato, transversim valde im- presso, elytris sat punctatis fasciis duabus dentatis (prima ad suturam extendente. epipleurisque auruntiacis, pectore anoque fiavo-piloso, antennarum clava aurun- tiaca basi nigro-picea tibiis posticis rectis. Long. '68. One specimen, Prairie Paso. This species closely resembles in appearance N. marginatus, but the thorax is less narrowed posteriorly, and the depressed margins are considerably broader, being, in fact, very much as in the preceding species, or N. n i g r i t a. Alophus d idy m u s, niger, opacus, ochreo-fusco subtiliter dense pubescens y rostro canaliculato, thorace dense punctato, latitudine vix breviore antice pro- funde constricto lateribus antice paulo rotundatis tenuiter canaliculato, vitta utrinque sublaterali densius pallide pubescente, elytris thorace sesqui latioribus, dense subtiliter rugose punctulatis, ochreo nigroque subtesselatis, gutta utrinque ante medium, alteraque ad dodrantem densius pallide pubescentibus. Long. *48. Fort Vancouver ; collected also by the late J. K. Townsend. Somewhat smaller and narrower than A. alternatus Say, and readily distinguished by the different form of the thorax and by the entire absence of elytral striae. I have adopted the name under which it is known in the Berlin Museum. I have several species of Curculionidae, from various sources, collected in Ore- gon, but being unable to determine with certainty the genera to which they belong, and being in truth not at all satisfied with the elaborate arrangement used by Schonherr, I forbear describing them until I can bring them all together ; re- flecting that more confusion may be produced by referring a species to an impro- per genus, than by suffering it to remain undescribed. Synopsis of the CEde.meridje of the United States. By John L. Le Conte, M. D. Although I can contribute but two new species, at present, to this small family of Coleopterous insects, it seems desirable that a concise list of the species already described should be presented, as the descriptions have become somewhat scattered, and some of the species have been placed in wrong genera. The trenera allied to Xylophilus are placed in this family by some entomologists, but the association does not seem natural, and the species are therefore not in- cluded in this synopsis.

For the complete synonymy of this species, which is found on both conti- nents, see Schmidt's memoir above quoted, and Redtenbacher's Kiifer, p. 623. The insect is most abundant in the vicinity of our cities, and has probably been introduced by commerce. The synonymy omitted relates to its occurrence on the eastern continent, and therefore has no place in our local fauna. Redten- bacher very properly unites Nacerdes with Anoncodes.

One specimen: New Mexico; collected by Mr. Fendler. The base of the thorax is only about two-thirds as wide as the apex ; the dorsal line is fine, but the transverse impressions are well marked. The mentum tooth is narrow, and very slightly emarginate at the tip. In these four species, the under surface of the tarsi is glabrous, and the outer margin of the two posterior pairs is deeply grooved. In my synopsis of Pteros- tichus (Journ. Acad. Nat. Sc.,2d ser., vol. 2) it will be seen that in closely allied species, the latter character is of little value. The same would seem to be the case in the present group, and no better proof is required than the remarks made by Baron Chaudoir, on the page immediately opposite that in which he insists strongly on the great assistance which is derived from it in distinguishing Cala- thus from Pristonychus. The real difference between the genera is precisely that so long ago made known by Erichson, viz., the length of the paraglossae, which in Calathus do not extend beyond the ligula, while in Pristonychus (and likewise in Pristodactyla and Taphria) they are very distinctly elongated. Anchtjs Lee. Palpi tenues, acuminati, maxillares articulo ultimo paulo longiore ; antennae filiformes, articulo lmo crassiore,. et longiore; mentum dente medio simplici; ligula truncata, paraglossis angustis longioribus. A curious insect, having very much the appearance of Diaphorus, but having the head less constricted posteriorly, and the elytra rounded at the apex ; the thorax is long and cordate, almost turned into a pedicel at the base, with the impressions elongate and very narrow ; the elytra are twice as wide as the thorax, oblong and convex, with the humoral angles rounded, and the apex scarcely 1854.] 39 sinuate ; the striae are deep and moderately punctured, the intervals are narrow, convex, and are each marked with a row of very fine punctures, from which pro- ceed very short hairs. The legs are moderately long, the anterior tibiae scarcely dilated at the apex, with the emargination extending nearly to the middle ; in the male the first three joints of the anterior tarsi are very slightly dilated, and furnished beneath with a few papilla3. The antennas are very slightly thickened externally ; the first three joints and the base of the fourth are smooth, but furnished with a few scat- tered hairs ; the first is longer than the third, and somewhat thicker than in the other genera of this group. The paraglossae are narrow, curved, and longer than the truncate ligula ; the tooth in the emargination of the mentum is moderately large, and almost acute at the tip. The palpi are slender and moderately long ; the last joint is elongate oval, and almost acute at the tip; that of the maxillary palpi is distinctly longer than the penultimate joint. It seems by its characters closely to approach Stomis, but the mandibles are not so long and the labrum is not at all emarginate. By the structure of the anterior tibiae as well as by the sexual characters, it evidently belongs to the* present group. 1.

Finding in this insect many of the characters of Stomis, I was misled by the very poor description of Mr. Laporte, (Etudes Entom. 1, 72) with which it agrees as closely as could be ex- pected, in every respect except size. Baron Chaudoir, as I have already ob- served in my synopsis of Pterostichus, (Journ. Acad. Nat. Sc, 2d ser., 2,) has since stated that Mr. Laporte's insect is Feronia fastidita Dej. Under these circumstances, the specific name adopted by me under error falls, and I take pleasure in giving to the insect the name under which it was communicated to me by Dr. Harris. Rhadine Lee. This genus only differs essentially from Platynus by the greater length of the third joint of the antennae, which is one half longer than the fourth joint ; the first joint is short, being about one-half longer than the second. The form of body is that of the first division of Platynus, but the margins of the thorax and elytra are more broadly rerlexed, and the elytra are strongly sinuate at the apex ; the antennas and feet are also longer. These characters give the insect a considerable resemblance, in general appearance, to Anophthalmia. 1.

Long. "41. Le Conte, Ann. Lye. 4, 219. One specimen (male) found near St. Louis, Missouri, was kindly given my by Dr. Engelmann. In the State of Ohio, Dr. Schaum procured a dark brownish black specimen, in which the sinus of the elytra was so strong, as to form on each side of the apex a tooth; the specimen was a female, but not having it be- fore me for examination, I cannot determine whether the difference is to be re- garded as sexual or specific, Platynus Bon. (emend. Brulle.) Under this generic name I group, after the example of Mr. Brulle, those spe- 40 [April, cies upon which Bonelli formed his three genera, Platynus, Anehomenus, and Agonum. My reason for preferring for this assemblage of species the name Platynus, is merely, that such was the name chosen by Mr. Brulle, who was the first entomologist to perceive the necessity of merging the groups into one genus. Two years afterwards, Erichson proposed to call the assemblage of Bonelli's three genera by the name Anehomenus, alleging that Platynus was in- applicable to most of the species, and that it had, moreover, been employed (in the form Platyna) for a genus of Diptera ; the first point, in the present state of nomenclature, need not occupy our attention; the second point is also without weight, since Platyna was proposed as a genus many years after the establish- ment of Platynus by Bonelli, and before it was shown that the latter genus in- cluded any other form than that to which it was limited by the author. The name Platynus was consequently not vacant, and its application in any form, to a genus other than that intended by Bonelli was improper. This genus, as here understood, contains a very large number of species, all agreeing in having the paraglossae scarcely longer than the ligula ; the mentum tooth distinct and not emarginate ; the palpi slender, with the last joint ahout equal to the preceding; the first joint of the antennae moderately thick, not longer than the third, which again is not longer than the fourth; the tarsi are filiform, and the ungues entirely smooth. The antennas are usually filiform, but sometimes setaceous. The form of body is variable, usually somewhat slender, with the elytra nearly twice as wide as the head or thorax, and oval or oblong, sometimes elliptical ; the elytra are either rounded, truncate or emarginate at the base, usually slightly sinuate at the apex, and sometimes almost truncate, in which case a form of body results not unlike Dromius or Metabletus. Occasionally the form of body is stouter, and the elytra are hardly one half wider than the thorax ; and in some west- ern species, unknown to me, the form is said to be almost similar to Calathus ; these latter species have been separated by Motschulsky as Tanystoma, (after- wards changed to Tanystola) ; the only characters given are, that the last joint of the palpi is longer than the preceding, and the posterior angles of the thorax ob- tuse. Scaphiodactylus (Chaudoir) is also said to have the palpi as in Tanystola, but the posterior angles of the thorax are acute. Not having identified these genera, I can with propriety say nothing in regard to them. The thorax is very variable in form, being sometimes oval, sometimes cordate, square, or rounded ; the margin is sometimes strongly reflexed, sometimes hardly visible. The interval between the second and third stria; of the elytra is always marked with punctures, or fovae, varying in number from three to seven ; some species, not known to me by personal observation, are described as having but two punctures. To facilitate the determination of our species, the following division into groups may be found useful. A.

The cases of difficulty, in referring species by this table, will be but few ; a species (P. quadratus) is placed in (f.,) which might, with almost equal propriety, be placed with (d.) ; still, the form is less slender, and the margin of the thorax much more obvious than in the latter group. P. crenulatus in group (F.) differs from the others of the same group, by the broader and more quadrate elytra ; still, its chief affinities appear to be with that group, and I have, therefore, not separated it from its allies. A. The species of this group are of a slender form and not winged ; the legs and antennae are long ; the thorax is obovate, usually elongate ; the posterior angles are obtuse and rounded at the apex ; the lateral margin is strongly reflexed, and is broader than usual. The elytra are regularly elliptical, with no distinct hu- meral angles ; they are sinuate towards the tip ; the lateral margin is broader than in any other group, and is strongly reflexed. This group corresponds to Platynus of Bonelli and Dejean. 1.

This species resembles in appearance P. sinuatus, &c, below, but from the absence of wings, and from the form of the thorax, I am induced to place it in the present division. The margin of the thorax is not as wide as in the other species, but is a little dilated towards the posterior angles ; the basal impressions are deep, and are destitute of punctures or lines. The elytra are slightly convex, and their lateral margin is somewhat narrower than in the preceding species. B a. Composed of winged species, of a piceous black color and slender form ; the antennas are long and setaceous; the thorax is strongly margined, a little wider than long, somewhat narrowed posteriorly, with the basal angles obtuse, neither prominent nor rounded ; the posterior transverse impression is strong, and the basal impressions moderately long and deep. The elytra are more than twice as wide as the thorax, truncate at base, finely margined, sinuate towards the extremity ; the humeral angles are rounded ; the striae are fine, and the third in- terstice has three punctures, the first being placed in the 3d stria, the other two in the 2d stria. 5.

Long. *42. San Francisco, California ; very abundant. Specimens occur with three, four, and even five punctures on the third interstice of the elytra ; the impressed lines of the basal impressions of the thorax are less distinct than in the preceding ; the antennae and palpi are nearly black ? the tarsi are sometimes dark piceous. I have distributed this insect under the name Anch. brunneo-marginatus (Mann. Bull. Mosc. 1843, 196,) but on reconsidering the matter, I find so many points of disagreement, that 1 am obliged to propose a new name. His description reads : "Apterus, niger, depressus, capite laevissimo inter antennas impresso, thorace longiore, subcordato, lateribus refiexo-marginatis, angulis posticis acutiusculis, 44 [April, elytris oblongo-ovalibus, apice sinuatis, leviter striatis, punctis tribus minutis impressis, antennis pedibus, thoracis elytrorurnque margine rufo-brunneis. Long. 4* lin. lat. H lin." With regard to the value of the first word of this diagnosis, I will merely ob- serve that it occurs also in Count Mannerheim's diagnosis of Anch. maeulicoUis (1. c. 199,) which, however, I found at San Diego, in July, flying about in the evening twilight in such numbers as to be a source of great annoyance. B c. The species of this group are moderately large, winged, and a pure shining black color; the thorax is slightly cordiform, with the posterior angles rectan- gular; the dorsal line and anterior transverse impression are deep ; the basal impressions are large, moderately deep and finely punctulate; the lateral margin is moderate and is strongly retlexed, and slightly diaphanous in a strong light. The elytra are more than one half broader than the thorax, truncate at base, slightly sinuate at the extremity ; they are somewhat flattened on the disc, and declivous towards the margin ; the stria? are deep, and the third interstice has three impressed punctures. I regret to be partly answerable for the confusion introduced among the species of this group, by mistaking those which have been already described, and incautiously admitting some which are not sufficiently distinct. Having carefully re-examined the subject, I hope that the results, here arrived at, may be found corrrct. 10.

The description last cited was made from a badly preserved specimen, in which the wings had probably been pulled off to enable the elytra to be brought together ; at least, on raising the elytra, I find fragments of the wings still remaining. The distinctive characters of the species are the larger size, the less distinct posterior angles of the thorax, (which are almost obtuse and very slightly rounded,) and the less lustrous and more flattened elytra. The .fine punctures of the striae are sometimes almost invisible. Dejean mentions four elytral punctures ; the second one, however, is abnormal. 11.

He says, in comparison, with the preceding, "le corselet est a peu pres de la meme forme ; seulement les bords lateraux sont un peu moins largement deprimes." This difference, if it exists, is by no means obvious. The only satisfactory characters I can find are the smaller size, the more shining, less depressed and less deeply striate elytra. a.

Although the difference between this and P. sinuatus seems very considerable, in a large series of the form (*) they seem to disappear ; 1 have therefore hesitated to propose a new name lor this, and consider it, like the previous one, as a race under P. sinuatus. C d. A group containing winged species, evidently allied to P. exte n si collis &c, but differing by having only three elytral punctures ; the feet and antennas are entirely black. The thorax is flattened, moderately margined, the margin growing broader towards the base; it is almost longer than wide, very slightly' narrowed posteriorly, hardly sinuate on the sides, truncate at base, with the pos- terior angles rectangular, not rounded ; the basal impressions are very long and finely rugous ; the elytra are flattened, truncate at base, slightly sinuate at apex ; the striae are deep and fine, the interstices flattish, the 3d with three impressed punctures ; the antennas are filiform. 12.

A group of extreme complexity, containing winged species of metallic colors, bluish or greenUh, with the base of the antennas, the feet, and occasionally the thorax rufous or pale piceous. The antennae are long and filiform ; the thorax is occasionally a little longer than wide, never much narrowed posteriorly, the margin fine, but strongly reflexed, moderately rounded on the sides; the base is oblique each side, and the posterior angles are obtuse and sometimes moderately rounded ; the basal impressions are long, and posteriorly are marked with a short line. The elytra are elongate, about twice as wide as the thorax, scarcely sinu- ate posteriorly, striae deep, but usually fine, the interstices hardly convex, the third with four to seven punctures, varying in the same species. By arranging the different forms as races under the more distinct species, this group appears to be capable of being reduced to order. 14.

I am doubtful about the propriety of referring this to Dejean's species, which is described as having the head and thorax obscure greenish-bronzed ; slight traces of such color may be perceived in some of my specimens, but usually they are of a brownish black color, slightly tinted with bronze. In the uncertainty which hangs over many of the species, and under my great want of success in collecting (or perhaps in identifying) the species found in California, it would be hardly prudent to pro- pose this as a new species. The refiexed margin of the thorax is distinct, but very narrow. D f. Winged species mostly of a black color, with the legs and antennae of the same color as the body ; the thorax is rounded, with the posterior angles very obtuse, or altogether rounded; the margin is moderately broad, usually slightly dilated and refiexed towards the base ; the basal impressions are broad and shallow ; the elytra are not much wider than the thorax, truncate, or even subemarginate at the base, rounded and hardly perceptibly sinuate towards the extremity ; the in- terstices are mostly fiat, and the third has three punctures, the second of which, except when otherwise stated, is placed on or near the third stria.

Sufficiently distinct from P. melanarius, by the slightly bronzed color, more obtuse and more rounded posterior thoracic an- gles, and less deep and impunctured elytral striae. From P. metallescens, which it resembles in the form of the thorax, it is easily known by the smooth elytral striae and more dull color. From P. moerens, it is distinguished by the wider thorax with more rounded base and less distinct posterior angles. Dr. Harris sent a specimen as Ag. collare Say ; the impunctured striae, how- ever, prevent it from being referred to the species described by him under the same name in the Trans. Am. Phil.

The first specimen described by me was defective in having very small elytral punctures, whereby I was led into the error of describing the elytra as having only three punctures on the third interstice. The thorax is larger and wider in proportion than the last spe- cies, but the elytra are wider and less elliptical than in the remaining species of this group, and the stria? are deeper. I am somewhat doubtful about referring Dejean's description to this species, since not only the first joint of the antennae, but very frequently three or four joints are paler than the outer joints, and the striae of the elytra, in comparison with the following species, could hardly be called fine. As, however, Dejean implies that the sides of the thorax are some- what reflexed posteriorly, I must acknowledge that my reference of his species to what is described below as P. picipennis, must be considered faulty. 45.

Many of the specimens have two slightly impressed foveae before the middle of the thorax, but some are found without such impressions.

A type of 0. cinctus, given me by Dr. Mel- sheimer, does not differ in any essential point from the other specimens. I have never seen any in which the lateral bead of the thorax was not testaceous, and am inclined to believe that Mr. Say had not a specimen of his Feroui a parmata before him when he described 0. cinctus. The basal impressions of the thorax are sometimes obsoletely punctulate, in other specimens they are quite smooth ; the elytra are sometimes nearly uniform brownish yellow, sometimes piceous, with the shoulders and sides indistinctly brown. 2. 0. micans, nigro-piceus, nitidus, cyaneo-micans, thorace rotundato, transverso, marline tenui testaceo postice subreflexo, basi utrinque vix late foveata, elytris ovalibus. basi emarginatis, tripunctatis, tenuiter striatis, mar- gine tenui testaceo, antennis palpis pedibusque flavis, ill is extrorsum fuscis.

On Fossil Coniferous Wood, from Prince Edward Island. By J. W. Dawson. Under the impression that any facts relating to the formation which lias af- forded the interesting reptilian fragment recently described by Dr. Leidy in the Journal of this Academy, will prove interesting, 1 beg leave to communicate the following results of microscopic examinations of the coniferous wood referred to in my note appended to Dr. Leidy's paper. I may premise that Prince Edward Island, which extends in an east and west direction about 130 miles, with an extreme breadth of about 35 miles, consists almost entirely of bright red sandstones, similar to the matrix of Dr. Leidy's fossil, with occasional bands of red clay, conglomerate and arenaceous and con- cretionary limestone. Over a large part of the island, these beds dip at very small angles to the northward. There are, however, some tracts in which the beds undulate to the southward and south-east. These red rocks, in their mine- ral character, much resemble the new red sandstone of Cornwallis and other 1854.] 6 r> places in Nova Scotia, and Dr. Gesner, in his Report on the Geology of Prince Edward Island,* notices the occurrence of trap dykes at two localities on the northern coast, a circumstance which still farther increases the resemblance. There are, however, a few places in which beds occur which much resemble the upper parts of the coal formation of Nova Scotia, and it is in these localities chiefly, though I believe not exclusively, that the coniferous wood in question occurs, along with a few other vegetable fragments, for the most part very im- perfectly preserved. Some interest, therefore, attaches to these fragments of fossilized wood, as a means of comparison between the oldest portions of the red sandstone formation of Prince Edward Island, and the inferior members of the coal formation on the opposite coasts of Nova Scotia and New Brunswick, in which coniferous wood is also of very frequent occurrence. 1. Coniferous wood from Gallas or Gallows Point , west side of Orwell Bay. At this place, which I visited in 1842, the following beds appear in descending order, the dip being to E. S. E. at angles of 6 to 8 : red and brownish sand- stones, gray sandstone with bands of concretionary limestone, and containing carbonized vegetable fragments, some of them resembling catamites, but without joints, gray and brown shales or indurated clays; brownish sandstone, with large trunks of trees silicified. One of these trunks measured three feet in its greatest diameter ; they are prostrate and somewhat flattened. I have no doubt that these rocks underlie the ordinary red sandstones of the island, and Dr. Ges- ner, who examined them in 1847, takes the same view, affirming them to be carboniferous, and stating that he found in them catamites and stigmaria, which, if well characterized specimens, would go far to confirm that conclusion. My specimens of fossil wood from this place are perfectly silicified, and of a dark clove-brown color. They are much fissured in the direction of the medul- lary rays, and the fissures are filled with flesh colored sulphate of barytes. Under the microscope, transverse slices show a somewhat dense tissue of quadrangular cells arranged in rows. Longitudinal slices in the direction of the medullary rays, show parallel elongated cells, medullary rays not strongly marked, and traces of hexagonal discs of the Araucarian type on the walls of the cells. Two rows of these discs occupy the whole breadth of a cell. 2. Specimens from Des Sables and Crapaud. At these localities the only rocks seen are the ordinary red sandstones, and the coniferous wood is found only in loose fragments on the surface. From the large quantity scattered over the fields, and the general scarcity of travelled boulders in this part of the island, I have no doubt that it now lies over or near its original site. The specimens from this place are dense and without fissures, and have a structure quite similar to that of the wood from Gallas Point, though not in so perfect preservation. 3. A specimen from, some part of the sovth shore of Prince Edward Island , now in the collection of the Puton Literary Society. This specimen was obtained from a person who stated that it was a portion of a large trunk. It still retains in its crevices remnants of the matrix of coarse reddish sandstone. It is cracked in lines radiating from the centre, and is perforated by numerous vermicular holes, now somewhat flattened, but which were probably the burrows either of Teredines or xylophagous larvae. Some parts of this specimen retain their structure in a very perfect condition. It is of precisely the same character with that already described, and shows one or two rows of discs on each cell. All these specimens probably belong to the same genus, and perhaps to the same species of coniferous trees ; and they all differ materially from the conife- rous wood of the coal formation. I have slices of the latter from various parts of New Brunswick, Nova Scotia and Cape Breton, some of them from the new- est beds of the coal formation. All of them are of much coarser texture than the specimens from Prince Edward Island. The cells are wider, and usually with three or even four rows of discs, and the medullary tissue is more strongly marked. In the closeness of the cellular tissue, fewer rows of discs, and fine- ness of the medullary rays, the Prince Edward Island specimens, though dis- tinctly of the Araucarian type, approach more nearly to the modern pines of this * 1847. 6 64 [April, country than to those of the coal formation. They therefore afford no proof that these lower members of the red sandstone formation of Prince Edward Island are of carboniferous date, but would rather tend to connect them with the overlying beds which have afforded the remains of the Bathygnathus borealis. The occurrence, however, in this position, of rocks so nearly resembling those of the upper coal formation, renders it probable that no very sudden or marked physical changes intervened between the deposition of the latter and that of the new red sandstones, and thus furnish an argument in favor of the Permian date of this last deposit.* Description of a species of Crane found in Wisconsin^ presumed to be new* By William Dudley, of Madison, Wisconsin.

Description of Fossil Trees in the coal rocks near Greensburgh^ Westmoreland county ) Pennsylvania* By Alfred T. King, M. D. Throughout nearly the whole of Western Pennsylvania, but more abundant in particular localities, may be found fragments of immense silicified trees lying on the surface of the ground. About seven miles east of Greensburgh there is a re- markable locality. Here may be seen immense logs from six to eight feet long, and from one to four feet in diameter, strewed over acres of ground. After the closest examination, I have been unable to find any very clear indications of high vegetable organization in these silicified trees. Indeed I have been unable, after the closest scrutiny, to discover a single specimen of fossil plant in our vast carboniferous series, of higher organization than vascular Cryptogamia. I might, perhaps, except some specimens, which I first saw a few weeks since in Beaver county, Pa., of Trigonocarpum? This is the fruit of a tree, which some have supposed to be allied to the Palms ; of this, however, there is still great doubt and uncertainty. Many of the specimens of silicified wood contain numerous and beautiful crystals of quartz scattered throughout their interior structure, which would seem to indicate that the silicifying process must have taken place whilst the wood was immersed in water of high temperature. Whilst excavating a tunnel on the Pennsylvania Railroad near Greensburgh, a stratum of very compact sandstone of about fifteen feet in thickness was opened', which contained vast quantities of trunks and limbs of trees, some per- meated with silicious and pyritous matter, whilst others have left only their imprints, the woody matter having been converted into coal, which forms a thin * For description of the Newer Coal Formation of Nova Scotia, see Journal of London Geol. Soc. vol. 1. p. 322 ; and Taylor's Statistics of Coal, p. 196. 1854.] 65 but beautiful pellicle, covering the impressions of the plants. These trunks and Jimbs are of all sizes, from an inch to nearly three feet in circumference, strewed about, and piled upon each other in the most irregular manner, and so numerous that scarcely a fragment of rock was thrown out which did not contain either a vegetable impression or a silicified stem. Although in the shale above, vast piles of detached fern leaves were found, be- longing principally to the genus Neuropteris t accompanied with numerous im- pressions of Calamites, yet no species of fern was discovered in the sandstone, with the exception of two specimens, both of which belonged to distinct genera. The one was a Pecopteris, and the other was the Cyclopteris trichomanoides , Among the numerous arborescent fossil plants which were found in this sand- stone, was an entire tree of immense magnitude, lying prostrate, about four feet above the Pittsburgh seam of coal, and about thirty feet beneath the surface. The part which was removed measured twenty six feet in length, and two feet ten inches in circumference at the base. From the size of the two main branches which enter the rock on the opposite side, I infer that this tree may have been from forty to sixty feet in height. At the base, it was much flattened by the pressure of the superincumbent weight, but strange as it may seem, the branches still retained nearly their original cylindrical form. It was entirely enveloped in a coating of pure bituminous coal, varying from a quarter of an inch to one inch in thickness. Its interior was filled with sand, mixed with sulphuret and car- bonate of iron, which much increased its weight, but there were no indications of vegetable structure. The thin vegetable band, which alone remained con- verted into pure bituminous coal, may have surrounded an axis of more perishable material, which, when the tree was removed from its original position by the storms or the Waves, rapidly decayed. Its hollow interior would necessarily be filled with sand, broken shale or other sediment which was brought by large rivers into that turbulent sea, the bed of which was gradually subsiding. This view is corroborated by the fact, that the rock in which this plant is found imbedded, and which constituted its matrix, presents an entirely different appear- ance in color, and in some degree in lithological character, from that which fills the interior of the fossil tree. Although there were numerous, but irregular longitudinal flutings, both along the main irunk and its branches, yet I could discover no indications of those beautiful scars, so characteristic of arborescent ferns, and of the genus Sigillaria, which indicate the spots where the petioles of the leaves articulated with the stem ; and hence I infer that this tree should not be referred to either of those families of plants. The question naturally arises, to which of the three great divisions of the vegetable kingdom do these fossil trees belong. Do they belong to arborescent ferns, gigantic palms or lofty pines ? Are they of exogenous or endogenous growth ? It has been said by fossil botanists, that true exogena? and endogenae have been found in the carboniferous rocks of Europe. I have, therefore, been much inter- ested in discovering some clear indications of these highest forms of vegetable structure, in the coal measures in this country ; but 1 have thus far failed, unless the specimens to which I have already alluded, should on further examination, prove exceptions. I am aware that M. Brongniart has placed the Sigillariae among the exogenae, but with all due deference to his high authority, I must say that I have been unable to find in that family of fossil plants any evidence of pith, bark, con- centric rings, medullary rays, or other indications of so high a structure. Since writing the above,! have made another examination of the specimens of fossil trees, and believe that I was at first mistaken in regard to some of them being branches. The rock in which they were found had been blasted, and consequently the fossil trees were much broken. The largest entire piece which I saw was not more than four or five feet in length. These facts may have some bearing upon their position in the vegetable scale. 66 [April, Description of fossil fruit found in the Carboniferous BocJcs of Beaver County , Pa* By Alfred T. Kijxg, M. D., of Greensburg, Pa. Mr. Mendenhall, of New Brighton, showed me several specimens of fossil fruit imbedded in solid sandstone, belonging to the carboniferous series of that neighborhood. And through the kindness of George W. Tyler, Esq., editor of the Boston Herald, I procured a specimen for description. These specimens bore considerable resemblance, both in form and size, to the fruit of the Butternut, Juglans cinerea. There have been found in the coal strata in Leicestershire, England, a number of species of a three cornered fruit, to which the generic name Higonocarpum has been given. Possibly, the specimen which I am about to describe, may be referred to that genus. This is a drupaceous fruit, of an ovoidal shape, from two inches and a quar- ter to three inches in length, and from one inch and three quarters to two inches and a half in breadth, and weighs from two and a quarter to three ounces* Its external surface is nearly covered with a thin coating of bituminous coal ; a large portion of which, however, adheres to its matrix. This coal was formed, I presume, by the carbonization of its pericarp. Its interior is filled with coarse grained sand, similar to the rock in which it was imbedded. The epicarp i formed of three nearly equal valves, joined by three prominent sutures, uniting in a point at the apex. Between the sutures are seen a number of nearly parallel and prominent longitudinal striae, which gracefully curve so as to meet in a point at the distal extremity. In all the specimens which I saw, there is a deep depression or excavation at the base, where the fruit was attached, in all probability, to a peduncle. This fruit is not triquetrous, as the name Trigonocarpum seems to indicate, but strictly ovoidal, sometimes nearly obovoidal, having three prominent sutures joining the three valves of the epicarp. It was found in Beaver County, Pa., about three miles from the town of New Brighton, in a thick stratum of compact, but coarse grained sandstone, near the middle of the carboniferous series. Should this belong to the genus Trigonocarpum^ 1 propose calling it Trigono- carpum carbonariwm. Descriptions of new Birds of Northern Mexico* By D. N. Couch, U. S. Army. 1. CORVUS CRYPTOLEUCUS.

History, dated April 20th, 1854, acknowledging the receipt of an entire copy of the Publications of the Academy, presented in accordance with a late resolution. Also a letter from the American Philosophical Society, dated April 27, 1854, acknowledging the receipt of the last number of the Journal and of the Proceedings. May 9 th. Vice-President Bridges in the Chair. Dr Le Conte presented a paper for publication in the Proceedings, entitled " Synopsis of the Cucuiides of the United States," which was referred to Mr. Cassin, Dr. Zantzinger, and Dr. Rand. Dr. Le Conte exhibited a fragment of the jaw of a new Pachyderm from the Tertiary of Virginia, 80 or 90 miles S. W. of Alexandria, and characterised it as a new genus allied to Dicotyles. Mr. Wm. Parker Foulke asked the attention of the Academy to a Lecture by Mr. Hugh Miller, recently republished in the United States, under the title, " The Two Records, the Mosaic and the Geological ;" and made some remarks upon the importance of maintaining a careful scrutiny of the logic of the natural sciences. The cultivators of those sciences are particularly interested at this time in pre- venting any misapprehension of the results of their researches, as there is a prevailing disposition to " reconcile " these by extreme processes with the popular interpretation of certain texts of the Mosaic history. Unfinished inves- tigations of the students of nature are used as complete evidence ; and provisional generalizations are employed as fixed premises, from which are drawn conclusions very inconvenient to subsequent inquirers and writers. Thus both religion and natural science are wronged. Mr. Miller teaches that in the attempt to reconcile the two "records," there are only three periods to be accounted for by the geologist, viz., " the period of plants, the period of great sea monsters and creeping things : and the period of cattle and leasts of the field ;" that the first of these " periods " is represented by the rocks grouped under the term palceozoic, and is distinguished from the secondary and the tertiary, chiefly by its " gorgeous flora ;" and that " the geological evi- dence is so complete as to be patent to all, that the first great period of organized being was, as described in the Mosaic record, peculiarly a period of herbs and trees yielding seed after their kind." The general reader, not familiar with the details of geological arrangement, could not fail to infer from such a statement, used for such a purpose, that the palaeozoic rocks are regarded by geologists as forming one group, representative of one period which can properly be said to be distinguished as a whole by its gorgeous flora ; and that it is properly so dis- tinguished for the argument in question. It was familiar to the Academy as well as to Mr. Miller, that from the carboniferous rocks downward (backward in order of time) there have been discriminated a large number of periods differing one from another in mineral and in organic remains; and that the proportion of the carboniferous era to the whole series is small, whether we regard the thickness of its deposits or its conjectural chronology. It is only of this carboniferous era, the latest of this series, that the author's remarks could be true ; and even of this, if taken for the entire surface of the earth, it could not be truly asserted that PROCEED. ACAD. NAT. SCI. OF PHILADELPHIA, VOL. VII., HO. III. 7 70 [May, " the evidence is so complete as to be patent to all ,5 that the quantity of its vegetable products distinguishes it from the earth's surface during the era in which we live. To confound by implication all the periods termed palaeozoic, so as to apply to them as a whole what could be true, if at all, only of the carboniferous period, is a fallacious use of a generalization made for a purpose and upon a principle not properly available for the writer's argument. The high esteem in which the character of Mr. Miller is deservedly held by readers in the United States, where his writings are widely circulated ; and the respectful manner in which his interesting researches have occasioned his name to be mentioned by authors eminent in the department of geology, give to such of his writings as bear upon the biblical question, peculiar importance with reference to the com- munity at large. Mr. F- urged the duty of insisting upon the maintenance of regular methods of exposition as well as of investigation, leaving apparent inconsistencies, which are beyond our means of explanation, to be "reconciled" by our successors with the aid of larger accumulations of knowledge than we possess. The progress of science has been retarded by the assumption that every discovery must be immediately proved to be harmonious with certain other portions of our knowledge. A due regard to the sacredness of religious faith and to the natural sensitiveness of the popular mind will secure respectful caution; but it is most consistent with the acknowledged imperfection of human faculties, and at the same time most worthy of the true dignity of science, to assume that ultimately all truths will be found to agree ; and meantime, strictly adhering to the canons of evidence, to explore courageously the great field open to us. We ought espe- cially to avoid generalizations which have no sound philosophical principle, or which are framed or applied merely from a desire to appease over-zealous minds ignorant of the facts already ascertained. This obligation is stronger in propor- tion to the degree of confidence given to the teacher in any case, and also in proportion to the limitation of access to other sources of information.

Dr. Le Conte presented a paper for publication in the Proceedings, -entitled " Notes on some new Coleopterous Insects from the Collections'' 1854.] 71 of the United States and Mexican Boundary Commission." Referred to Mr. Cassin, Dr. Ruschenberger and Dr. Leidy. Dr. Le Conte also presented a paper from Mr. Charles Grirard, on a new species of Salmonidae from the Northeastern part of the United States, which was referred to Dr. Le Conte, Dr. Leidy, and Dr. Hallowell. Dr. Brinton desired to draw the attention of the Academy to a new mode which he had recently devised and practised in the preparation of anatomical specimens, several of which he exhibited. Anatomical specimens, he said, had hitherto been preserved either in the wet state, or else dried ; both plans were open to objections. If animal tissues be immersed in alcohol, or other preservative fluids, their color becomes blanched, their structure condensed, and consequently their size and shape to a certain degree modified ; and at the same time they present incon- veniences for demonstration ; whilst in the dry state, as for example, in the ordin- ary dried preparation of our cabinets, the parts are so shrunken and changed, as to convey but an imperfect idea of their primitive relations. As this shrinkage of the tissues, and the decomposition are dependent most probably upon atmospheric influence, Dr. Brinton stated that it had occurred to him some time since, that should he be able so to exclude the air, as to prevent all evaporation from taking place, he would perhaps succeed in preventing, not only the desiccation of the part, but also its decomposition. Influenced by this idea, he had commenced a series of experiments, and the suc- cess up to this time accompanying them, had led him to draw the attention of the Academy to the subject. His object being to encase hermetically every portion of his specimen, Dr. Brinton remarked that he had selected for his earlier experiments, a solution of gun cotton in ether, the ordinary collodion. This he applied by means of a brush over every portion of the external surface of his preparation. The ether quickly evaporating, a thin film of the cotton was deposited upon and in all the interstices of the tissue. This process was repeated until a layer of sufficient thickness had been obtained; successive coatings of copal and shellac varnishes were then ap- plied, so as to rentier to the preparation a certain degree of firmness and stiffness. But it soon became evident to him that collodion was not entirely suited for the generality of objects, especially for those of any considerable bulk. It possesses too slight a degree of tenacity, and is liable to become easily chipped and fissured. It was necessary, therefore, to employ some other material, and a solution of gutta-percha in benzole was selected ; this was applied in a similar manner over the object to be preserved. The pellicle left by the evapora- tion of the benzole was tenacious, dense, and could be increased to any de- sired thickness. Single layers were transparent, suiting admirably for layers of fasciae. For the encasement of the adipose tissue, collodion was still employed. The thick coating, however, which it was considered necessary to apply upon the muscular mass, was of course opaque ; hence, it became of importance to re- sort to an artificial coloring process, and for this purpose, collodion stained with the wood of the Pterocarpus santalinus, (the ordinary red saunders,) was found to answer admirably. The color resulting imitated closely that of fresh muscle. The preparation was then completed by the repeated application of copal and shellac varnishes. . Dr. Brinton explained to the Academy, that he did not present his specimens as tried and perfected preparations, for as yet they had attained the age of but some twenty days ; but merely as evidences of the application of a new principle to the preparation of anatomical objects. Time was required to test its value. Whether or not any internal decomposition could take place in consequence of the retention of a residual amount of air, Dr. Brinton could not state; but he doubted that such would be the case, to a degree sufficient to affect the contour of the specimen. Should, however, such a result ensue with regard to the speci- mens upon the table, still his experiments had shown that the process was ap- 72 [May, plicable to any tissues which had been injected or soaked with a solution of the chloride of zinc, or any other antiseptic. Here decomposition would be impossible, and the gutta-percha was certainly sufficient to prevent the shrinking consequent on evaporation. Dr. Brinton then stated that he was still experimenting, and had succeeded in procuring a colorless solution of gutta-percha in benzole and in chloroform, which would supersede the use of the collodion for the adipose matter. These transparent solutions would doubtless be applicable to the preparation of dissec- tions of the nervous system, and to pathological structures. He stated also that he thought possibly an extension of this principle might hereafter be made sub- servient to the preservation of any fresh animal tissue. Further results would be submitted to the Academy. May 23c?. Vice-President Bridges in the Chair. Letters were read From Dr. Wm. Wirtenweber, dated Prague, 30th Oct., 1853, trans- mitting several of his works, acknowledged this evening. From Dr. W. D. Hartmann, dated West Chester, Pennsylvania, May 16, 1854, acknowledging the receipt of his notice of election as a Corres- pondent. Dr. Le Conte presented a paper by Mr. C. Girard, and intended for pub- lication, entitled " A list of North American Bufonides, with diagnoses of new species." Referred to Dr. Hallowell, Dr. Leidy,and Mr. Hanson. Dr. Leidy called the attention of the members to specimens of four vertebras of a huge extinct saurian, from near Greenville, Clark Co., Arkansas. They had been kindly loaned by Mr. W. F. Roberts, an agent of the Arkansas Mining Company, who had discovered them with numerous others. Dr. L. stated, that in his late visit to St. Louis, Mr. Albert Koch, the industrious collector of fossil remains, had exhibited to him a collection of bones from the same State, and apparently of the same animal, which he was on the eve of sending to Berlin. The specimens on the table are remarkable for the robust transverse processes, which project laterally from the lower part of the body, and terminate in a large facet for the articulation of a rib. The bodies are cylindroid, and are terminated by slightly concave or nearly flat articular surfaces. The sides of the body are moderately concave, and have an acute margin at the articular surfaces. On each side of a median prominence pf the under side of the body a large vascular foramen exists. These vertebrae resemble those of the Cirnoliasaurus mag?ius, from the green sand of New Jersey, described previously in the Proceedings of the Academy,* but in that the large transverse process is cylindrical, while it is compressed cylindroid in the Arkansas saurian, and probably this latter belongs to a distinct genus, for which the name Brimosaitrus grandis is proposed. The bones are embedded in a hard limestone with mollusca, and they probably belong to the cretaceous or to the eocene period. One of the most perfect of the vertebroe presents the following measurements : Length of the body , 3| inches. Depth of articular surfaces 5 " Breadth of " 6 Length of the spinal arch ... 3 References of Plate II. Figs. 1 3, Brimosaurus grandis. : 6, Cirnoliasaurus magnus.

The posterior angles of the thorax are usually prominent, on account of the sinuosity of the sides near the base ; sometimes this sinuosity is very faint, then the posterior angles, although rectangular, are not prominent. Newman's C. punctic-ollis (Ann. Nat. Hist. 2, 398) is described as having but 6 striae on each elytron, (the 5th and 6th stria? are said to be indistinct.) Now, in some specimens, which cannot be separated from C. rufus, the fifth and sixth striae are not well marked, but in all that I have seen the seventh stria is quite obvious. As the elytra are declivous at the sides beyond the seventh stria, I think it probable that this seventh stria is constant in the gpnus, in which case there is no reason why Newman's species should not be united with C. rufus.

Abundant throughout the United States, in articles of commerce, herbaria, &c. This species, although placed by several entomologists in the present genus, has so much the form of Paramecosoma, that any person would be tempted to refer it to that genus. The first joint of the abdomen is not longer than the second, and therefore, according to Erichson's definition, it would be excluded from the family of Cryptophagides. In this essay must be included the description of a remarkable insect, of which my unique specimen is in such a bad condition, that I am unable to determine whether it should be referred to any described genus, or even to indicate its po- sition in the group ; from its specific characters, I suspect a relation with Pedi- 1854.] 79 acus, but the size of the eyes and the form of the thorax are very different.

Mr. Motschulsky informs me that the insect here described is congeneric with the Russian Physemus velutinus mentioned by him in his catalogue of the Hydrocanthares of Russia, (p. 12,) and I have acordingly adopted the name proposed by him. The insect is of small size, broadly ovate in foyn, subacute posteriorly. The antennae are longer than the head, the first four joints are thick, the second being a little shorter, the fifth and sixth are somewhat less thick, the seventh slender, as long as the sixth: the club is oval, not much broader than the first joint, and apparently solid, though with a high magni- fying power, it appears indistinctly articulated. The most remarkable char- acter is that this club is received in a deep hole, each side of the thorax, on the zipper surface, just behind the anterior angle. The feet are slender, and formed as in Linnichus. 1.

Differs from P. fusca, (which appears to be confined to the Pacific coast,) in a more distinct patch of chestnut on the crown, not merely tinged with this color; lighter throat, the rusty color extending further down, as do the attend- 120 [June, ant spots, and below these again, a large dark spot partially covered "by the feathers, and not observed in specimens of P. fusca. The middle of the breast and abdomen clear white, the rusty of crissum extending further on the belly. The bill is more rounded and shorter, the tarsus shorter, and the outer claw extends further on the middle claw. Pipilo aberti is easily distinguished by the black lores and chin, less distinct spots on the throat, and nearlj r uniform under parts. A specimen collected by Mr. Clarke, of the Mexican Boundary Survey, at the Copper Mines, appears to belong to this species. It has unfortunately lost its tail. The chestnut patch is paler. A smaller race of the same was col- lected by Lieut. Couch at Santa Catarina in Mexico. Centurus uropygialis, Baird. Head and neck all round, and the lower parts of the body brownish ash, darkest above ; a broad frontal band of dull yellowish white, (not golden.) A small quadrate patch directly on the vertex, of deep red ; rest of the upper parts banded transversely with black and white, even on the rump and upper tail coverts. Middle of the belly yellow, sides of the body along crissum, and lower tail coverts banded with black and white, like the back. Primaries black, white at the base ; secondaries with round spots on the outer web ; two central tail feathers black on the outer vane with a narrow stripe of white at the base, running for half the length of the feather near the shaft, and tapering to a point ; inner vane banded alternately with black and white ; two exterior feathers on each side banded on both vanes ; intermediate ones entirely black. Total length 9 inches, extent 16, wing 5, tails 4 l-10th. Differs from C. carolimcs in yellow belly, resembles it in character of trans- verse bands above, and markings on the tails. C. flaviventris has the middle tail feathers entirely black, and the rump and upper coverts white. C. tricolor has the middle of belly red. C. uropygialis also lacks the golden front and occiput of this and other species. Bill- Williams Fork of Colorado, New Mexico. 1351.] 121 July 4/A, 1854. Major Le Conte in the Chair.

Description of Neiu Species of Viviparous JMarine and Fresh-water Fishes, from the Bay of San Francisco, and from the Fiver and Lagoons of the Sacra- mento.* By VV. P. Gibbons, M. D. In the first paper that I read before the Academy, descriptive of these fishes, I placed them among the Labroids, on account of their corresponding in charac- ters to this family, as established by Cuvier. Prof. Agassiz, however, in a letter received from him, objects to this classification, because of the recent modifica- tions which have been made in the characteristics of the Labroidae. This question will be settled by a more intimate acquaintance with this extraordinary family, which probably comprises a large number of species yet undiscovered. The anomalous phases of animal and vegetable life in California, indicate the necessity of patient and thorough investigation before coming to final conclusions respecting the characters of new fishes. In my present descriptions, therefore, I place these fishes provisionally in the Family LABROIDAE. Genus Holconotus. Head of medium size ; body subeomprf-ssed, arched ; lips thick.

The anatomy of these is similar to that of the viviparous species which I have already described, except that the uterus, instead of being bipartite at its anterior extermity, is ovoid, and has but a single system of uterine blood vessels. The specimens from which this description is made were presented to me by my friend, Dr. J. B.

By John Lindley, Ph. D., &c," in which the diagnoses of the two families mentioned are as follows : 1854.] 129 Algales. Cellular flowerless plants, nourished through their whole surface by the medium in which they vegetate; living in water or very damp places, pro- pagated by zoospores, colored spores or tetraspores. Fungales. Cellular flowerless plants, nourished through their thallus, (spawn or mycelium.) living in air; propagated by spores, colorless or brown, and sometimes inclosed in asci ; destitute of green gonidia. Now all the entophyta in question, excepting such as are especially described as fungi, are flowerless plants, and are nourished through their whole surface by the medium in which they vegetate; aad they live in a watery liquid, (the intestinal contents,) have no mycelium, and are propagated by spores in the manner of many undoubted algae ; and, therefore, they agree with the former diagnosis, and not with the latter. They even differ in a very important char- acter from Saprolegnia, (which on page 17 of the " Vegetable Kingdom," under the name of Achlya, is placed among the algae,) which possesses a mycelium, as I have frequently observed in this curious plant growing upon dead flies, earthworms, salamanders, &c.

The origin of the spiny dorsal is situated opposite the base of the pec- torals, and the origin of the anal, opposite the space between the eleventh and twelfth dorsal spines. The tip of rays, as well as the base of anal, extends a little farther back than the dorsal. The base of ventrals falls upon the same vertical line as that which would intersect the base of pectorals. Scales of medium size; minutely serrated. Greyish brown above, silver grey beneath. Irregular transverse bands of dark brown or black, interrupted along the lateral line, the portion of the band above it is somewhat alternating with the portion beneath it. A large black spot may be seen at the upper angle of opercle. Specimens from Sacramento River, Cal. COTT1D.E s. Cataphracti. 2. Cottopsis gulosus, G.

Preopercle provided with two small spines, such as may be observed in several species of Cottus proper, the head otherwise is smooth; mouth proportionately large; posterior extremity of upper maxillary reaching a vertical line, which would pass behind the pupil. A space of five twentieths of an inch exists between the 12 130 [August, origin of the first dorsal and the occiput. Second dorsal connected with the first by a low membrane proceeding from the last spiny ray. Tips of posterior soft rays not quite reaching the base of caudal. Anal, about as high as second dorsal, but shorter. Caudal, well developed and posterioily rounded. Origin of ventrals midway between the tip of lower jaw and the anus.

Head broad and large, forming a little less than the third of the whole length. Body tapering rapidly backwards. Orbits raised above the surface of the skull, which exhibits a parieto-occipital carina. Above and inwardly of nostrils a rough plate is observable. Preopercle provided with four spines, uppermost very long, extending backwards to the posterior edge of opercle ; the two next ones are small and directed obliquely downwards; the fourth, may be seen at the lower edge of that bone and directed obliquely forwards. The opercle has three spines; a stout one along the upper margin of that bone, and two small ones towards its inferior margin and directed obliquely downwards. The posterior extremity of interopercle. finally exhibits the last and smallest spine of the opercular apparatus. The isthmus is rather large. The first dorsal begins at a very short distance from the occiput, and is separated from the second by a similar small space. Its base is contained once and a half in that of the second dorsal, the po-terior rays of which, do not reach the base of the caudal. The caudal in itself is rather long. The origin of the anal is under the fourth ray of second dorsal ; the tips of its posterior rays are almost even with those of the last mentioned fin, although its base does not extend as far behind. The ventrals are long and slender; their insertion being nearly equidistant between the symphysis of lower jaw and the vent. The tips of pectorals reach a vertical line, which would intersect the second ray of second dorsal fin. D VIII. 12. A 9. C 4. 1. 5. 4. [.5. V I. 3. P 16.
