ACADEMY OF NATURAL SCIENCES

OF PHILADELPHIA.

January 3dy 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,

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.

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.

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 :

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.

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 wrhich 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 wTould 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.

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 wras 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 wrhich 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

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

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 betwreen 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-

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-

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

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 pubescensy
rostro canaliculato, thorace dense punctato, latitudine vix breviore antice pro-
funde constricto lateribus antice paulo rotundatis tenuiter canaliculato, vitta

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.

This species is very closely allied to D. lae v is of Europe, but differs by the
thorax being finely punctured, less rounded on the sides, less narrowed posteri-
orly, and by the basal angles being less prominent.

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.

should be separated from Asclera, with many of the species of which it
agrees in form.

Georgia: although resembling the next species in color, this is readily dis-
tinguished by the absence of elevated lines on the elytra, and by the basal joint
of the antennae being longer than the third joint : the thorax is also of a different
form, being regularly obovate, and without a transverse impression. The an-
tennae and anterior tibiae are sometimes slightly fuscous.

LABRIBJE.

HERICHTHYS, B. and G. — Body compressed ; outline subelliptical ; frontal
region convexe. Teeth small, subcorneal, simple, anterior row the most con-
spicuous. Lower lip entire. Five branchiostegal rays. Ventrals, dorsal and
anal fins acuminated ; caudal rounded. Five or six spiny rays to the anal. Scales
large ; lateral line interrupted posteriorly.

Obs. — This genus has strong affinities with Heros of Heckel, from which it
chiefly differs by the structure of tlTe anterior row of maxillary teeth, which are
simple, instead of bein^ provided with lateral hooks. The relative size of the
scales will likewise afford another generic feature of no small importance.

8. Herichthys cyanoguttatus, B. and G. — Head forming about two-sevenths
of the entire length. Snout subconical, detached from the frontal line by a de-

N<ote ou the genus Amblychila, Say.

By John L. Le Conte, M. D.

In a small bottle of specimens of Coleoptera, collected in New Mexico by

Major Sibley, U. S. A., recently sent me through my kind friend Prof. Baird,

was fortunately contained a specimen of Amblychila; as some confusion seems

-still to exist with regard to this very rare insect, a few remarks may not be out

of place.

Fort Union is about seventy miles E. N. E. from Santa Fe, and consequently
«ear the base of the Rocky Mountains; it will be remembered that Say's speci-
men was also obtained near the same chain, although at a point farther north.
This fact, as well as the complete agreement of the specimen with Say's de-
scription, fixes it as an authentic type of A. cylindriformis. The outline (Plate 1)
wood cut appended to this note was made by Mr. W. Van Ingen, from a
drawing by G. G. White, and is very accurate in form. It will readily enable
'the necessary comparison to be made wilh the Californian specimen described by
Mr. Reiche, which I believe was afterwards purchased by Baron Chaudoir.

On comparing the New Mexican specimen with Mr. Reiche's figure, (Am.
Ent. Sue Tr., vol. S, pi. 19, also copied into Chenus. Encyc. Hist. Nat.) several
important differences may be perceived: the head and thorax of his is propor-
tionally narrower, and in the enlarged figure of the head, the labium is repre-
sented as having a quite prominent tooth each side of the emarginate medial pro-?
longation, and the lateral angles are rounded; in mine, the labrum each side of
the prolongation is merely slightly sinuous, and the lateral angles are rectangu-
lar, so that the general outline each side of the middle is decidedly concave. The
'large punctures in the side figure seem to form a regular series between the
-costa and the suture, wThile in mine they are distributed irregularly.

In comparison with the description given by Mr. Reiche (1. c. p. p. 560), I
have only to say, that my specimen shows a quite decided brownish tinge on the
elytra, while the Californian specimen is described as entirely black; and that
the smaller punctures of the elytra are by no means obsolete. Mr. Reiche's re-
mark in the generic description, that the basal tooth of the mandibles is bifid, ap-
plies only to the right mandible : that of the left side has, it is true, a correspond-
ing prominence, but it is so small and so far back, as not to alter rhe outline in
any way, and therefore Mr. Reiche's observation tends to produce confusion.

I should not at all hesitate, therefore, to consider the Californian A. P i c c o-
1 o m i n i i as distinct from Say's species, were it not for the preposterous collar
which, in Mr. Reiche's figure, is appended to the base of the thorax, and for the
very inaccurate representations given by his draughtsman of the two species of
Omus found in Oregon, (I. c. 7, pi. 10.) Such figures might be excusable in
America, where artists have not yet turned their attention to objects requiring
such accuracy of delineation, but in parts of Europe where accurate figures have
been made, and as the yearly accessions to our scientific libraries show can still
be made, such figures as those published in the Annales above quoted, of Am bly-
chila and Omus, are hardly to be commended.

Having found near San Francisco, in California, some specimens of Omus
californicus Esch., I avail myself of the present occasion to remark, that
it is very closely allied to O. A u do u in i Reiche, and in fact only differs by
having the head and thorax very densely and deeply wrinkled, and the punctures
of the elytra more equal in size : the appearance of rows of punctures jiiven in
the very wretched figure accompanying Eschscholtz' description (Zool. Atl. tab.
4, fig. 1,) and copied by Reiche (1. c. sup ) is hardly apparent.

The epipleurae in Omus are narrow, and defined by an acute line, which unites
with the margin near the apex of the elytra. In Amblychila the epipleurae are
broad, and the defining elevated line becomes obsolete about one-fifth from the
tip. The discoidal costa is about the same length : the intermediate costa (called
by Say the marginal elevated line) is more elevated, and extends to about one-
seventh from the tip : the smaller punctures of the elytra become effaced
towards the tip, and the large ones (each of which bears a small elevated point,)
are somewhat more numerous.

From Prof, Haldeman, addressed to the Corresponding Secretary,
dated Columbia, Penn., 29th March, 1854, as follows :

" I find that the Limnadella described by Mr. Girard, Proceed. Acad. vol. 7,
page 3, is my Limnadia coriacea, ib. 1, 184, for June, 1842. At that time I
doubted the propriety of placing it in Limnadia, chiefly on account of the dorsal
tubercles mentioned in my description, but I had no means of making the neces-
sary comparisons. It was discovered in great abundance in a road-side puddle,
subject to desiccation, and although I removed a number of them to a small pond,
I have never met with them since."

Dr. Le Conte presented a paper, for publication in the Proceedings,
entitled " Synopsis of the species of Platynus and allied genera, inhabit-

Synopsis of the species of Platynus and allied genera, inhabiting the United

States.

By John L. Le Conte, M. D.

The species of the small group of Carabica, herein examined, are quite fre-
quently so closely related, as to be with difficulty separated ; some synonymy
too has been produced by the want of sufficient bibliographical knowledge on the
part of those who have investigated these genera. To lessen in some degree

36 [April,

the difficulty now resting over the subject, I have thought that a series of origi-
nal descriptions of all the species known to me, based upon a careful comparison
of their specific characters, might remove some of the obstacles encountered from
the different style of the descriptions of different authors. I do it the more gladly,
as an opportunity is thus afforded me of correcting many important errors into
which I was led, in some of my earlier writings, by the haste and inexperience
of youth, from the effects of which it falls to the lot of only the most favored of
men to escape.

The reader will find, in some portions of this essay, a further development of
the principle announced by me in a synopsis of Silphales, (Proc. Acad. 6, 275,)
illustrated in a genus, of which the species are very numerous ; these species
form small groups, according to their respective affinities, and in general the
limits of each species are marked by well defined organic differences. But in
some of the groups, occur forms so closely allied as to present, with a large series
of specimens, almost imperceptible differences, by which sets of specimens, at
first sight readily recognized and separated, become linked together. These
variations (in form, not color) are frequently seen to be constant in those found
in one locality, and in the present condition of science, would seem to indicate
positively the origin at different points, or at various points intermixed together,
of organic forms, so closely related as not to present sufficient differences to be
regarded as ordinary species.

Thus it is that Nature who, not only between her works, but between her
processes, continually displays gradations of sublime harmony, reveals to u,s~ some
of the steps between those genera in which absolutely distinct species are found
in restricted localities, and those in which absolutely the same species are found
widely distributed.

The genera known to me with the exception of a single new one, have been
fully described in other works, and may be thus arranged :

Mentum dente bicuspi ; ungues plus minusve serrati :

Paraglossae ligula non longiores .... Calathus.

Paraglossae longiores, ultra ligulam extensae . . Pristodactyla.
Mentum dente simplici ; ungues simplices :

A common species in the Middle and Eastern States, and is found occa-
sionally at Lake Superior. The North American species of this genus are very
closely allied, and seem hardly worthy of being separated; ^nevertheless, the
three species recognized by me in the Atlantic portion of the continent, are as
well distinguished from each other as from those of the Pacific coast. This one
will be readily recognized by the shining lustre and the moderately broad re-
flexed lateral margin of the thorax; in the next species the lateral margin is
narrower, perceptibly depressed, and not at all refiexed towards the posterior
angles. For authentic specimens of this species I am indebted to Dr. Harris.

rower in its form, and with the lateral margin of the thorax not distinctly wider
towards the posterior angles, and less reflexed.

punctis tribus impressis, antennis palpis pedibusque testaceis. Long. «35 — 42.

Middle, Southern and Western States; rare. This species, with the form of
C. gregarius, has the dull elytra and finely impressed strias of C. ruficollis ; it
seems also sufficiently distinct from the preceding species, by the sides of the
thorax being' depressed, broader behind and not reflexed.

4. C. qu a d r i c o 1 1 i s, longiusculus, piceus, apterus, thorace latitudine

San Francisco, California. This species is narrower than C. ruficollis, and is
readily distinguished by the form of the thorax; the thorax and head have a
reddish tinge, but do not appear ever to reach the deep, dull rufous color observed
in C. ruficollis.

5. C. ruficollis, latiusculus, piceus, apterus, capite thoraceque piceo-rufis,

testaceis. Long. -35 — -4.

Dej. Sp. Gen. 3, 78 ; Mann. Bull. Mosc. 1843, 195.

San Francisco and San Diego. Considerably wider than any of the preceding
species, and with the sides of the thorax anteriorly more rounded ; the sides con-
verge a little near the base, whereby the posterior angles are rendered less rec-
tangular than in those above described. This species and the preceding, fre-
quently subject travellers to great annoyance by crawling over their bodies at
night, when sleeping on the ground ; the multitudes which are seen in March
and April, under every object capable of affording them shelter, are worthy of
admiration.

6. C. ob s c u r u s, minus elongatus, piceus, apterus, thorace latitudine non
breviore, antrorsum angustato, lateribus rotundatis (angulis basalibus obtusiori-

striis tenuibus non profundis, punctis tribus impressis, antennis palpis pedi-
busque iufo-testaceis. Long. *4.

One female found in the Southern part of California. This species differs from
C. ruficollis and C. quadricollis by the form of the thorax, which is not wider
than long, considerably narrowed in front and moderately rounded on the sides,
which are distinctly depressed even to the base, and hardly reflexed. The elytra
are more distinctly wider than the thorax, but otherwise are formed and sculp-
tured as in C ruficollis.

Middle States ; rare. Smaller than the next, and distinguished by the thorax

38 [April,

being more distinctly narrowed towards the base, and by the elytra being slightly
dilated from the base to the posterior third.

I have great doubts of the propriety of separating this genus from Taphria ;
the very slight difference in the form of the last joint of the labial palpi, which
is less dilated in the American species, is surely insufficient. From the differ-
ence in the form of the ungues, noticed in the species below, I am inclined to
believe, that a natural arrangement would require all the genera (so called) of
this group, in which the mentum tooth is emarginate, the paraglossae longer than
the ligula, and the ungues serrate, to be united into one genus. The species
contained in Pristonychus, Pristodactyla and Taphria do not appear more dif-
ferent from each other than those embraced in Platynus.

Lake Superior ; not rare on the northern shore; a specimen from the north-
eastern boundary of Maine was kindly given me by Mr. Brevoort. More slender
than any of the other species here described, and very similar in appearance to
some of the smaller European Pristonychus. The mentum tooth is much less
emarginate than in the preceding.

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.

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.

Massachusutts, Dr. Harris; Illinois, Mr.Willcox. 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.

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.

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. Corpus apterum gracile ; thorax fortiter marginatus, ovalis ; elytra humeris

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.

Found in the mountains near Santa Isabpl, in the southern part of California.

Middle and Western States, in the vicinity of mountains. Besides the punc-
tures mentioned, there are several on the sutural stria before the middle. De-
jean's description is very full, but lest any entomologist should hesitate in refer-
ring this species to the description given by Say, which is certainly defective in
some particulars, I transcribe it to save the labor of future reference.

lated, distinctly indented, angles obtusely rounded, lateral edge regularly ar-
quated. Elytra, striae not deeply impressed, irregularly punctured. Thighs and

" This species seems to belong to the genus Pterostiehus of Bonelli, and it may
be distinguished from those which we have mentioned to be referable to that
genus by the color of its feet."

One specimen, found at Sault Ste Marie. 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.

One specimen, found at the Sault Ste Marie. Although very much resembling
the next species in all its characters, the thorax is comparatively so much nar-
rower, that I am obliged to consider it as distinct. The base of the thorax is
more obliquely truncate each side, by which the basal angles are rendered more
obtuse. By a clerical error the specific name is printed angusiicollis, in Agassiz'
Lake Superior.

Middle and Southern States ; common. The last two synonyms belong to a <
variety in which the interstices of the elytra, instead of being slightly convex as
usual, are entirely flat ; there are, however, no other differences of a definite
character, and I see no reason why they should be retained as distinct. The
brevity of Mr. Haldeman's description will make it doubtful whether this or
the preceding species was meant, but a typical specimen kindly furnished me by
'him evidently belongs to the present species.

Dr. Harris possesses a specimen of this species, which was named Feronia
maculifrons, by Mr. Say; with the description (Journ. Acad. Nat. Sc. vol.3, p.
146) of that species it does not agree.

B— b.

Containing two winged species from California, closely allied to those of the
preceding division, but of a somewhat less slender form, and with filiform an-
tennae. The thorax is strongly margined, slightly narrowed towards the base,
with the posterior angl°s obtuse, not rounded, and slightly prominent; the pos-
terior transverse impression is deep, and the basal impressions shallow ; the
elytra are twice as wide as the thorax, truncate at base, with the humeral angles
rounded ; they are finely margined and very slightly sinuate towards the tip; the
strise are fine, the interstices slightly convex, and the third has frequently four
impressed punctures, which, however, seem liable to considerable variation ;
the normal number appears to be three.

San Diego, California. The lateral margin of the thorax is moderately wide
and not dilated posteriorly ; the basal impressions are marked with a short im-
pressed line at the bottom. Apart from color this species is distinguished from
the next by the narrower thorax and more slender form.

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.

Middle and Southern States ; not common. 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.

really Dejean's species. 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.

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.

C— e.

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.

between the basal impression and the angle being distinct. The punctures of
the base are fine, occasionally extending along the whole base, but sometimes
visible only in the impressions. The color of the elytra sometimes varies to-
wards bluish and coppery. The under surface is black.

this species, but as the fine punctures of the elytra are not mentioned in his des-
cription, it will be safer to consider it as distinct ; in some specimens of («) they
might, however, readily be overlooked.

San Francisco, San Jose and San Diego, California. 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. A numerous

Middle States, abundant; Vermont, Dr. Harris. The more reflexed thoracic
margin the deeper basal impressions, and the distinct tubercle near the angle
will readily separate this species from P. Harrisii. Dr. Harris thinks that this
is not the species intended by Dejean. As, however, the latter says that the
tibiae, tarsi and basal joint of the antennae are sometimes of a brownish color, I
think that he cannot refer to any other of our species having three elytral punc-
tures. A specimen having the thorax a little longer and less regularly rounded
on the sides, was sent me, by Dr. Harris, under the name Agomim nitidum \ I
cannot, however, find sufficiently definite characters to separate it.

Middle and Eastern States, rare. 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. Soc. as above quoted.

Massachusetts and Lake Superior. The inequalities of the elytra are pro-
duced by irregular dilated shallow impressions along the course of the striae : the
most obvious of these is usually near the extremity of the fifth striae : Dr. Harris
regards this as specific, and therefore applied to the species the unpublished
name Ag. sulcatum. The thorax is less transverse and less rounded than in the
preceding species, and the sides are less distinctly reflexed towards the base.
The second elytral puncture is on the second stria.

Massachusetts, Dr. Harris. Although differing in size and color, so as to pre-
sent no resemblance whatever to P. Harrisii, the form and structure is very
much as in that species : the posterior angles of the thorax are more distinct,
and the elytral striae deeper : as in that species, the second elytral puncture is

Northern shore of Lake Superior. The thorax perhaps most nearly resembles
that of P. melanarius, but the base is more rounded, and the basal angles hardly
to be determined : the elytra are but little wider than the thorax, and more con- -
vex, giving the insect very much the form of Pterostichus erythropus. In one
specimen the striae of the elytra are impunctured, in another they are obsoletely
punctulate.

San Francisco and San Diego, California, not rare. I was inclined to refer
this species to Agonum brevicolle Dej ., (Sp. Gen. 3, 159) but on examining seve-
ral specimens, I find that the elytral punctures are always three: the second is
placed about the middle on the third stria, as in most of the species above
described : the lateral margin of the thorax is hardly wider towards the poste-
rior angles than at the middle: the basal impressions are sometimes slightly ru-
gous and punctulate. The form of the thorax is somewhat that of P. Harrisii,
but is less rounded on the sides.

One specimen, Oregon. Enough remains of the antennae and feet, to show
that they were black. This species has a comparatively smaller thorax than
the others of this group, and seems to establish a passage towards group (C — d,)
from which, however, it differs in having the basal impressions of the thorax
more excavated, and not prolonged anteriorly. The sides of the thorax are
moderately rounded anteriorly : the second elytral puncture is placed on the
second stria.

mention the punctures of the base of the thorax, nor of the striae of the elytra, I

but on comparison it is found completely different. The basal impressions of the

posterior angles. The third interstice of the elytra has only three very small
punctures, of which the second and third are placed on the second stria.

near the third on the other ;) the striae are deeper and very finely punctulate ;
from P. subcordatus, it differs by the longer thorax.

F.

Winged species of a slender form, usually black, sometimes, hower, piceous,
and in one instance of a metallic green color ; the base of the antennae and the feet
are yellow ; the thorax is oval, with the margin narrowly reflexed becoming
broader towards the posterior angles, which are rounded and indistinct; the
basal impressions are narrow, sometimes deep and smooth, sometimes nearly
obsolete. The elytra are elongate oval, twice as wide as the thorax, moderately
convex, emarginate at the base and obliquely subtruncate at tip; the striae are
fine, the interstices flat, the third marked with five or six punctures.

Lake Superior, Massachusetts and New York. 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.

Lake Superior, Maine, Illinois, New York, Georgia, Santa Fe. Readily recog-
nized by its greenish or bluish black color; the elytral punctures are usually six
in number, of which the two posterior are situated in the second stria, the others
on the third. Varieties occur having the legs of a uniform dull reddish color.

California, in every part west of the Sierra; the elytra are distantly and very
obsoletely punctulate ; of the punctures the two anterior are placed in the third,
the others in or near the second stria. The thorax is sometimes entirely testa-
ceous. By a strange error Count Mannerheim has added the word Ct apterus " to
the diagnosis, which he has otherwise copied almost literally from Dejean; the

56 [April

insect is always winged, and at San Diego, in June, occurred in such numbers,
flying in the twilight, as to be very troublesome.

Lee. Ann. Lye. 5, 178.

San Francisco, California; under bark of dead trees. The four anterior of the
elytral punctures are placed on the third, the posterior three, or two (as the case
may be) are adjacent to the second stria. In one specimen there are only three
punctures on the third stria, the other four being on the second. The basal im-
pressions do not combine with the concavity near the margin (as in P. placidus)
but remain distinct.

Mr. Motschulsky (Bull. Mosc. 1845, pars 1, 21,) has mentioned a species
under the name Agonum limlatttm, which may be identical with our insect. He
merely states, " in size and form it resembles closely A. p e 1 i d n u m, but is
readily distinguished by the whitish margin of the elytra." The specific name
is, however, preoccupied by Say.

H— k.

A group containing species of a robust form, but flattened body ; the color is
more or less metallic ; the legs and antennae dark colored or black ; the thorax
has the posterior angles somewhat distinct, but not prominent; the margin is
very narrow, but not reflexed; the basal impressions are shallow and prolonged
anteriorly. The elytra are scarcely one half wider than the thorax, emarginate
at base, very slightly sinuate at the tip ; the striae are well marked, but fine ; the
third interval has from five to seven punctures.

55. P. deplanatus, aeneus, virescens, modice elongatus, thorace rotundato-
quadrato, tenuiter marginato, latitudine breviore, postice parum angustato, basi

Agonum deplanatum Menetries, Bull. Petrop. 2, 58. (1844.)
Abundant at San Jose. The original description mentions that the striae of
the elytra are finely punctulate ; this character may be observed in some speci-
mens, but is usually not apparent. The basal impressions of the thorax are
sometimes very obsoletely punctulate ; the punctures of the third interval of
the elytra are not adjacent to either stria.

Anchomenus fossiger Mann. Bull. Mosc. 1843, 199.

California, at San Francisco, San Jose, San Diego, and the Colorado River.
Varies not only in color, but even in form ; the thorax is usually distinctly wider
than long, and considerably rounded on the sides ; the basal impressions are
broad and obsoletely prolonged anteriorly to the middle, and occasionally slightly
punctulate.

a. This is a single specimen from San Francisco, in which the thorax is not
wider than long, almost square, and less rounded on the sides than in the other
specimens, but with the posterior angles less distinct and more rounded. The
general form of the body is narrower, but as I have not found the characters
sufficiently distinct, it would be imprudent for the present to separate it under
another name.

I.

r A group of small black winged species, having the thorax transverse, rounded
at the sides and base, with the posterior angles very obtuse, but usually distinct ;
the margin is narrowly reflexed, especially towards the posterior angles; the
basal impressions are not obvious, being lost in the concavity between the mar-
gin and the disc ; the elytra are oblong, and flattened ; they are deeply emarginate
at base ; when the elytra have three small punctures, they are almost truncate
at tip, and are slightly sinuate: when I he elytra are deeply foveate, the sutural
portion is more prolonged, so that the truncation becomes oblique. The striae
are veiy fine and badly defined; the legs and antennae are black; the latter area
little stouter than usual, though hardly perceptibly so.

57. P. c o n s i m i 1 i s, niger, nitidus, thorace subquadrato transverso, basi et
lateribus latins rotundato, angulis posticis distinctis, margine tenui reflexo pos-

bus, tenuiter striatis, subtiliter tripunctatis. Lon^. *32.

One specimen ; Michipicoton, Lake Superior. Differs from P. obsoletus by its
larger size, less rounded base of thorax, and much more distinct posterior angles.
The four anterior trochanters are red. As in the next two species, the apex of
the elytra is almost truncate, and as in them the second puncture is in the second
stria.

58. P. obsoletus, niger, nitidus, thorace transverso, postice subangustato
basi valde rotundato, angulis posticis obtussissitnus, margine tenui reflexo pos-

New York and Lake Superior. The error by which I referred this species to'
Feronia placida Say, is entirely unaccountable. This common species frequently
has the anterior and middle trochanters of a deep red color. I have received a
typical specimen named by Say, through the kindness of Dr. Harris.

Oregon, at Prairie Paso, and Fort Vancouver, Dr. J. G. Cooper ; northern
part of the west coast of America, according to Count Mannerheim. This spe-
cies is very closely related to the preceding, but the thorax is wider posteriorly,
thus becoming more quadrate, the posterior angles are more distinct, and there-
flexed margin is a little wider. The elytra are comparatively much shorter,
being not more than one half longer than wide, while in P. obsoletus they are
fully twice as long as wide; the basal impressions of th° thorax, though long,
are very indistinct; in the preceding they cannot be traced.

Agonum bembidioides Lee. Ann. Lye. 4, 227.

One specimen, Lake Superior. Closely resembles the next species, but is
sufficiently distinct by its larger size, and the irregularly mottled appearance of
the elytra.

Kirby's genus Sericoda was formed on an erroneous examination of the palpi

58 [April,

of a distorted or mutilated specimen. Chaudoir (Bull. Mosc. 1844, p. 70) has
established a genus Rhytiderus, upon Dromius 10-punctatus, from South Ame-
rica, but which, as observed by Erichson, (Bericht fiber Kntom. 1844,) be-
longs to Kirby's Sericoda. The relation between the genus Sericoda, and a very
common insect of northern Europe, does not, however, appear to have been
suspected by any of the authors,

61. P. stigmosus, aeneo-niger, subnitidus, thorace transverso subquadrato,
basi rotundata, postice subangustato, angulis posticis obtusis at distinctis, elytris
oblongis, tenuiter striatis, utrinque foveis magnis quatuor impressis. Long. '21.

Flatynus quadripunctatu$\ Lee. Agassiz' Lake Superior, 206.

Very abundant at Lake Superior, and found also in Maine and New Hamp-
shire. Dr. Schaum tells me that he considers this as the same as the European
P. quadripunctatus, and in my catalogue of Lake Superior Coleoptera, I gave it
as such on his authority. On comparing, however, a large number of specimens
with one found in Sweden, the posterior angles of the thorax, although very ob-
tuse, appear to be always well defined, while in the European specimen the
angles and the base are rounded together, so that the apex of the angle cannot
be defined.

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

Pennsylvania, Indiana, Georgia. 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.

Leeonte, Ann. Lye. New York 4, 230.

Georgia and Louisiana. Readily distinguished by its small size; the striae of
the elytra are finer than in 0. parmatus, and the intervals perfectly fat ; the
margin of the thorax is a little reflexed and broader towards the base.

Feronia scutellaris Say, (Journ. Acad. Nat. Sc. 3, 146) is a diseased specimen
of one of our black species, allied to P. melanarius.

Anchomenus pubescens Dej. (Sp. Gen. 3, 122) of which Anch. obconicus
Eald. (Proc Acad. 1, 299) is a synonym, does not belong to this group, but
forms a genus A t r a n u s Lee. (Ann. Lye. 4, 438,) allied to Chlaenius.

The European Platynus angust icollis Dej . is mentioned by Kirby (Fauna
Bor. Am. 23) as being found on this continent in lat. 54° and 65°; his descrip-
tion seems to apply to one of the species of division (B — a,) and probably to
P. marginatus ; a comparison of specimens is, however, desirable in order to es-
tablish the synonymy.

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

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

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 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

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 Neuropterist 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.

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.

the Publications of the Academy, presented in accordance with a late
resolution.

Also a letter from the American Philosophical Society, dated April

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

" 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 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.

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 :

•55 of an inch. 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.

Sitka ; I have not seen this species. By an oversight, Mr. White, in the British

Museum Catalogue, quotes Motschulsky for the name.

By another oversight in the same Catalogue, C. sanguinolentus and haema-
todes, European species, are mentioned as found in North America, while our
common species, C. clavipes, is said to inhabit South America. Reference to
these errors is perhaps needless, as attention has already been called to them by
Schaum, (Bericht, &c. 1851, p. 55t) but they are merely mentioned in this place
for the information of those to whom Schaum's Report is not accessible.

shorter than in P. planus, and the inequality of the joints from the fourth to the

faintly striate. The impressions of the thorax consist of two longitudinal ones
concave outwards, which are connected near the base and apex by transverse
impressions.

A common species found in the Middle and Southern States, and as far west
as Nebraska. The under surface is frequently rufous, but is sometimes as dark
as the upper surface. As this species is more densely punctured than the next,
and agrees in this respect with the European L. moni 1 i s (Cue. bipzistulatus
Panz.) with which Say compares it, I have concluded that this is really Say's
species ; the typical specimens in the Melsheimer collection render this view
certain.

The head of the male is as wide as the thorax, and. the antennae two-thirds as
long as the body.

A unique male specimen of this beautiful species, found in York Co., Pennsyl-
vania, was kindly given me by Dr. Melsheimer under the name here adopted.
Body above and beneath bright rufous, shining, glabrous. Head as wide as the
thorax, slightly convex, finely, moderately densely punctured ; vertex finely
channelled ; before the eyes is a line transverse arched line ; the outline of the
front is concave each side and emariiinate in the middle, which is not so much
produced as in the two preceding; the labrum is short; mandibles long and
slender, emarginate at tip. Antennas moderately stout, nearly as long as the
body. Thorax twice as wide as long, considerably narrowed at the base, sides
strongly rounded, sinuate near the posterior angles, which are sharp and promi-
nent ; disc moderately convex, finely punctured, with the lateral line not strongly
impressed. Elytra not wider than the thorax, moderately convex, with 7 or 8
very fine striae, on which are placed moderately large punctures; the interstitial
spaces are marked with a few very fine punctures, which on the sutural space
form a somewhat regular series ; their color is black, with a large, common, tri-
angular, rufous spot at the base, which along the suture extends one-third the
.length; the apical margin is slightly reddish. The scutellum is transverse,
without any distinct apical angle.

One female found at the junction of the Colorado and Gila Rivers, California.
The large, slightly elevated, dorsal convexity of the thorax will readily distin-
guish this species. The head seems to be nearly smooth, and the anterior trans-
verse line is distinct ; the antennas are a little more than half as long as the body,
and their joints are rounded.

Abundant at the Colorado River, California. The head is finely and sparsely
punctulate, the vertex is slightly channelled, and the anterior transverse line is
deep ; in the male the head is as wide as the thorax, and the antennae are as

Pennsylvania and Maryland, Mr. Zimmermann ; Illinois, Mr. Willcox. This
very small species is readily distinguished from the next by the finer punctua-
tion and the absence of the outer marginal line of the thorax.

S. Carolina, Mr. Zimmermann. The small punctures of the elytra appear to be
near the striae, but not upon them, and form two series between the striae. The
antennae of the male are as long as the body, and the first joint is as long as the
head, or about equal to the three following united. The outer marginal line of
the thorax is not distinct.

Louisiana and Georgia, Dr. Schaum. The outer stria of the thorax is distinct,
but does not reach the base. The antennae of the female are two thirds as long,
those of the male almost as long as the body ; the first joint is equal to the two
following united in the female, and is a little longer in the male. This species
is very closely related to the last, but seems, by the difference in the form of the
thorax and by the differences in the antennae and elytra, to be properly sepa-
rated.

Colorado River, California, abundant. The head is very finely punctulate,
and is distinctly channelled posteriorly; the discoidal impression of the thorax
is very faint, but it causes the anterior margin, in particular lights, to appear
slightly elevated. The male only differs from the female by the broader head
and longer and thinner antennae ; in both sexes, the first joint of the latter, al-
though thicker, is but little longer than the second.

A very singular species, of which I found but a single male at the Colorado
River, in California. The head is quadrate, with parallel sides, and without im-
pressions ; the usual marginal line is distinct. The mandibles project beyond
the labrum, and are about half as long as the head, the tip is emarginate. The
labrum is broad and slighrly emarginate ; the antennae are more than half as long
as the body ; the first joint is not much larger than the second, but the last three
joints are distinctly larger than the preceding and subtriangular. The scuiel is
triangular. The under surface of the body is black, with the antennae and feet
piceous.

Georgia, not rare. Differs from the preceding by the thorax being not dis-
tinctly transverse, less strongly toothed at the sides, with the anterior angles
acute, but very slightly produced ; by the stria of the elytra being less punc-

species has the thorax formed almost as in the preceding, the anterior angles being
a little more produced ; the elytra are, however, deeply striate, with the inter-
stices more rough with elevated punctures; they are also more strongly carinate
towards the side. The sexual characters as in the preceding species, but in ad-
dition, the elytra of the male are longer, and obliquely slightly sinuated at the
apex.

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-

retain for it the name which appears in Dejean's Catalogue.

Georgia. The antennae are longer than the head and thorax, with turbinate
joints, gradually increasing in size ; the first joint is thickened, and is longer
than the two following united. The last joint of the maxillary palpi is larger
than the penultimate and apparently acute at tip. The angles of the thorax are
all rounded ; the posterior foveae are oblong, slightly oblique, and about as far
from the sides as from the base.

Notice of some Coleopterous Insects, from the Collections of the Mexican Boun-
dary Commission.

By John L. Le Conte, M. D.

This paper includes descriptions of some new species contained in collections
received from the Boundary Commission immediately before the completion of
the survey, and with the collections previously made by the active and enter-
prising naturalists attached to the expedition, will enable a moderately full
Coleopterous Fauna of the lower Rio Grande to be prepared.

Of the species noted below, some were collected between Laredo and Ring-
cold barracks, by Messrs. Schott and Weise, under the command of Major Emory.
Those from Frontera, Rio Grande, were collected by Mr. J. D. Clark, under Major
Graham : a few others were obtained by Mr. Clark at San Antonio, in Texas.
Some very interesting species from Fort Union, New Mexico, collected by Major
Sibley, are also added, although not belonging properly to the Boundary fauna:
and one from Dr. Cooper's collection in Oregon, which was omitted in my de-
scription of his species.

Cicindela punc tul ata and albohir ta. Frontera; Mr. Clark.

Cicindela 16-punctata Klug. Jahrb. 32. Frontera; Mr. Clark. This
species resembles very closely C. Hentzii, nor does there appear in Klug's de-
scription any character which would separate it from that species. The law of
representative forms is abundantly exemplified in the species of this genus, and
much careful investigation will be necessary to determine what are well defined
limits of the species.

C. bland a? A species closely resembling this was also found by Mr. Clark
at Frontera.

Pasimachus costifer, niger, nitidus; thoracis elytrisque marginibus cyanes-
centibus, illo postice angustato, lateribus postice sinuatis angulis posticis rectis,
his modice convexis, laevibus, carina humerali postice obsolete continuata, cos-
taque submarginali acuta utrinque paulo abbreviata ornatis : antennarum arti-
culis 2 et 3 compressis. Long 1-05 — 1-2.

Dr. Weise, Laredo to Ringgold Barracks. This species has the same form
as P. depressus and pnnctulatus, but the sharply elevated costa between the
margin and the obsoletely prolonged humeral carina will readily distinguish it,
The mandibles are slightly rugous.

Santa Fe, New Mexico, Mr. Fendler : Frontera, Mr. Clark. This species is
comparatively almost as elongated as H. erraticus, but the thorax is more

80 [May,

narrowed posteriorly, the lateral margin is narrower, and the elytra of the female
are not toothed near the apex : the posterior angles of the thorax are slightly
prominent, and almost rectangular.

Laredo to Ringgold Barracks; Mr. Weise. This curious little species seems
to have most affinity with those of Burmeisters division {& (2)) ;* the anterior
tibia? have three large external teeth, the mandibles are without any prominent
external tooth, and the elytra without any short series of punctures near the
scutellum. It differs, however, from all those described by Burmeister in hav-
ing in place of the two usual frontal tubercles a transverse ridge, scarcely emar-
ginate at the middle. The prosternal prominence is small, acute and densely
pilose.

At Vallecitas, in California, I found the elytra and thorax of a species which
seems on comparison very similar to the specimen found by Mr. Weise, but be-
longs to a section of the genus having a short stria at the base of the elytra, be-
tween the first and second stria: the punctures of the elytra are more closely
set, so as to form striae ; the thorax is more densely punctured anteriorly, and
almost smooth posteriorly : the dorsal channel extends almost to the apex, but is
not deep, and finally the anterior tibiae above the three long teeth have an indis-
tinct prominence representing a fourth tooth. The length was about '65 of an
inch. The species may be called P. i 1 1 a t u s.

Athyreus ser r a tu s, ferrugineus, nitidus, clypeo antice truncato elevato,
vertice transversim elevato, thorace lateribus rotundatis serrulatis, antice valde

valde marginato, elytris tenuiter striato-punctatis, antennis flavis. Long. -54.

One specimen, Laredo to Ringgold Barracks. The head is finely scabrous ;
the clypeus is truncate and perpendicular at the apex, which forms a subtrian-
gular facet; each side above the eye commences an elevated line, which runs for-
ward to the angle of the lateral emargination of the clypeus, then in a curve
runs to the apex, where it unites with the elevated edge of the triangular facet
above mentioned : the vertical horn is very short and transverse. The thorax
is sparsely punctulate, with a few large punctures along the middle, and in the
concavities: each side at the middle is a broad transverse sulcus, limited ante-
riorly by an elevated line ; anterior to this the disc is very declivous, with the
anterior margin strongly elevated; at the middle of this declivous face is a shal-
low impression, and again each side a deeper excavation, between which and
the first mentioned elevated line is a strong somewhat oblique elevated ridge :
the sides are regularly rounded and serrate, the anterior angles are acute. The
striae of the elytra are fine and moderately punctured ; the interstices are very
sparsely punctulate. The under surface and the legs are furnished with long
yellow hairs.

Although this is the first authentic appearance of the genus Athyreus in our
fauna, I find on comparison that Bolbocerus fossatus Hald. (Proc. Acad. 6,
362,) and Scarabaeus ferrugineus Beauv. (Ins. 90, tab. 2b, fig. 3,) also be-
long here; the middle coxa? in both of those species are separated, and the meso-
sternum is somewhat elevated, acutely margined at the sides and declivous ante-
riorly. In his beautiful monograph of Athyreus, Klug suggests that the species
of Beauvois just mentioned belongs to this genus, although in the absence of
specimens for examination, this opinion could not be confirmed.

long as the remaining portion. A nearly allied species from Wisconsin, given
me by Mr. Guex, may be thus described.

One specimen, Frontera (Rio Grande), Mr. Clark. This species differs from
H. lithophilus, by the thorax being longer, and scarcely narrowed anteriorly,
and by the fine punctures of thorax and elytra being very distinct: the striae of the
latter can hardly be traced. Its characters approach most closely to H. Gilensis
Lee. (Pro. Acad. 6, 43), a species of a broader form, and with very distinct lines
of punctures upon the elytra.

One specimen, Laredo to Ringgold Barracks, Mr. Schott. The general form

riorly and is less sinuate on the sides, and the punctures of the elytra are much
larger.

One specimen found with the preceding. Remarkable for the strange form of
the antennas, and for the sudden narrowing of the thorax behind the middle :
there is however, no posterior transverse impression, except the constriction in
the sides : the middle of the base is slightly elevated and marked with an oblong
fovea. It is closely related to C. brunnea Mels., but is smaller, with the thorax
much more narrowed behind.

One specimen, Mr. Schott. In form resembles E. atomarium, but is not quite
so robust: the thorax is scabrous with large punctures, the dorsal callosities are,
as usual, three in number, one medial elongated, the others each side in front of
the middle. The head around and between the eyes is densely pubescent with
whitish hair : the elytra are moderately shining, the punctures are not very
dense and become very small towards the apex. The thighs are not armed.

Laredo to Ringgold Barracks, Mr. Schott. Remarkable for its very slender
form, in which it almost equals E. unicolor, (Stenoc. ■unicolor Randall) : the
fourth joint of the antennas is armed with a very minute spine : the following
joints are unarmed, as are the femora: the spine of the third joint extends two-
thirds the length of the fourth joint. The elytra are truncate at tip, but the
truncate part is slightly emarginate, in such manner that the angles become a
little prominent. The antennae of the male are longer, those of the female
shorter than the body.

hind the middle are flat.

Fort Union, Major Sibley. The first five joints of the antennae are densely
clothed beneath with fine short erect hair : the apex of the fourth joint is hardly
thickened, but at the apex of the fifth joint is an internal brush of long yellowish
hairs, wThich are recurved, so as to form a hooked prominence. The form of the
thorax in this species is quite different from A. nodosus, and is more similar to
Monohammus, the spine being perpendicular, and the disc more cylindrical : it
ought probably to form a new genus, but as the arrangement of the genera of
Longicorns is still very unsatisfactory, it is needless for the present to separate
species that are obviously allied.

Prairie Paso, Oregon, Dr. Cooper. This very .fine insect seems allied to
Necydalis ; it differs, however, by its less constricted neck, and by the propor-
tions of the joints of the antennae, also by its stouter form : the elytra diverge
more posteriorly, showing a tendency towards a subulate form. The scutel is
smooth and shining, with the sides hairy : the pectus is thinly clothed with gray-
ish hairs.

Laredo to Ringgold Barracks. Mr. Schott. The arrangement of Buprestidae
is at present in such confusion, that I am unable, by the books, to determine the
proper reference of this species. Generic characters of much importance in this
family have been lost sight of in the arrangements proposed, and a thorough re-
vision is necessary. This particular species has for generic characters : clypeus
broadly but regularly emarginate ; the antennae inserted under a strongly elevated
line which runs obliquely towards the emargination of the clypeus ; the labrum
emarginate; the mentum rounded anteriorly; the scutel small, transverse and
rounded : coxal plates much but gradually dilated internally : rnesosternum di-
vided, with the portions entirely connate with the metasternum : palpi almost
cylindrical, with subequal joints : anus very slightly emarginate : tarsi with the
joints 1 — 4 broadly lobed, the lobe of the fourth joint rounded : the basal joint of
the posterior tarsi very little longer than the second: the mandible are thick,
short and obtuse.

Frontera (Rio Grande), Mr. Clarke. Although having very much the form of
Anthaxia, this species differs considerably in its generic characters ; the an-
tennre palpi and feet are unfortunately wanting, but the following marks will
enable the genus to be recognized :

The antennae are near the eyes, (which are moderate in size) and are inserted
on the front : behind the insertion is a deep fovea, at the bottom of which is a
round shining tubercle* (as in Dicerca) ; the clypeus is very broadly emarginate
in the arc of a circle, (labrum wanting) ; the mandibles are short, thick and ob-
liquely truncate; the mentum is broaci and rounded anteriorly; the rnesosternum
firmly connate with the metasternum; the posterior coxal plates with the poste-
rior outline concave so as to form an internal tooth; anus not emarginate ; scutel
very small, subtriangular.

The yellow margin of the thorax is posteriorly separated from the disc by an
impressed line : the yellow of the elytra is slightly dilated behind the humerus
»nd again about the middle.

Fort Union, New Mexico, Major Sibley. This beautiful species is nearly of
the same form as our common black P. longipes, but is less acute posterior-
ly : the yellow lines of the elytra are arranged so as to include the following
spots : a large common triangular one at the scutel, separated from the base by
the red margin ; an elongated lateral spot extending from behind the humerus to
two-fifths the length: a large common rhomboidal spot on the suture, extending
from the second to the fourth fifth of the length : immediately opposite the ex-
ternal angle of the rhomboid, a small submarginal black dot ,• finally a large api-
cal blotch ; separated from the rhomboid by a narrow yellow line, and from the
margin by the red marginal line above mentioned. The yellow stripes which
bound the anterior faces of the rhomboid are considerably broader than the

Laredo to Ringgold Barracks, Mr. Weise. The sides of the thorax are strongly

One specimen, Laredo to Ringgold Barracks, Mr. Weise. This species agrees
in its characters very closely with the two California species described in the
Annals of the Lyceum of New York, (5, 129) the mentum is however more flat-
tened, slightly carinate at base, and impressed anteriorly ; the antennas are less
slender, and the joints are more distant, and the last joint is not truncate, but
oval and pointed, and but little smaller than the tenth joint. A close affinity to
Centrioptera is also seen, but that genus has less produced prosternum, and" the
mentum is not emarginate.

Fort Union, New Mexico, Major Sibley. Probably a female : the antennae are
not filiform as in M. angusticollis Say, nor thicker in the middle as in M. im-
pressus Klrly, but are very gradually thickened to the end : the third joint is
not longer than the fourth, and is about twice the size of the second. The inner
spur of the posterior tibiae is acute, the outer one is larger, concave and obtuse.
This species approaches the Western American M. strigulosus Mann., but the
thorax is not so much elongated, the sides are nearly straight, and the base less
emarginate.

middle but very slightly curved : the second joint is one half larger than the
third. In the female the first joint extends to the posterior margin of the eye,
and the second joint is about equal to the third. This species is allied to L. longi-

guish it at first sight.

Notice of a new species of Salmo??idcB, from the north-eastern part of the

United States.

By Charles Gieard.

The body of the male is subfusiform and rather slender, particularly the caudal
region ; the head being regularly subconical and contained five times in the total
length. The maxillaries are gently curved, extending backwards to about the
posterior margin of the orbit. The female is stouter, with the peduncle of the tail
shorter ; the head has the same general shape, but is not contained five times in
the total length. The maxillaries are less curved, but extend as far backwards
as in the male. The eye is very large ; its diameter being contained nearly five
times in the length of side of head. The caudal is deeply emarginated posteriorly,
giving to it a more forked appearance than in either Salmo oquassa or Salmo
sebago. The adipose fin, in the male, is situated opposite the anterior margin of
the anal, whilst in the female it corresponds to the posterior margin of the same
fin.

The scales are well developed, being somewhat smaller, however, than in
Salmo sebago, and considerably larger than in either Salmo oquassa or Salmo
erythrogaster. On the dorsal and ventral regions they are considerably smaller
than upon the sides and along the peduncle of the tail. They extend, diminish-
ing in size, over nearly the half of the length of the middle rays of the caudal fin.
The lateral line takes an almost straight course along the middle region of the
flanks. The following is an approximate formula of the rays of the fins:

D 3. 12. A 1. 9. C 8. I. 8. 9. I. 5. V 1. 9. P 14.

There are two anterior rudimentary rays to the dorsal, one or two to the anal,
one to the ventrals, eight or ten to the upper lobe of the caudal, and five or six
to the inferior lobe.

The uppnr surface of head and dorsal region are blackish brown; the sides are
silvery white, and the belly yellowish. The region above the lateral line is
densely spread all over with black irregular spots, some of which are confluent;
a few scattered ones may be seen beneath that line upon the middle of the abdo-
men. Four to six of these spots, wrell defined, are always observed on the oper-

8

culum, one of which may occasionally reach the preoperculum. A few reddish
orange dots, individually situated in the middle of a black spot, are occasionally
observed along the middle and upper part of the flanks. Whether these dots are
peculiar to the female or proper to both sexes, I am not prepared to say, from
want of sufficient information, upon that point.

This species was first brought to my notice by M. Townend Glover, of Fish-
ki'i Landing, Dutchess Co., New York, who caught it in the upper affluent of
Union river, in the State of Maine, during the middle of September. I propose
for it the name of Salmo gloverii, as a token of gratitude towards an artist whose
labors, if promoted, would contribute so much to popularize natural history, and
spread its benefits throughout the country.

A list of the North American Bufonids, with Diagnoses of New Species*

By Charles Girard.

1. Bufo americanus, Le Conte MS. Holbr. N. Amer. Herp. v. 1842, 17,
pi. iv.

Inhabits the Atlantic States, from Maine to Virginia, extending through the
mountainous regions of the Carolinas into the valley of the Mississippi. It is
likewise found in the North Western States and Canada.

2. Bufo lentiginosis, Holbr. N. Amer. Herp v. 1842, 7, pi. i. — Rana
le7itigi?wsa, Shaw, Gen. Zool. iii. 1, 1803. 173. PI. liii. — Bufo erythronotus ,
Holbr. Ibid. 11. PI. ii.

Ranges along the sea coast, from South Carolina to Florida, and following the
gulf through Alabama and Mississippi. Scattered individuals are met with
across the mountains to South Carolina.

Bufo ctythrojiotus does not appear to us different from B. lentiginosus^ since
color alone cannot be taken as an exclusive guide amongst the bufonids.

3. Bufo woodhousii, Girard. — Bufo dorsalis, Hallow, (non Spix). Proc.
Acad. Nat. Sc. Philada. vi. 1852, 181 ; and in Sit.greaves Exped. Ziini and Color.
Rivers, 1853, 142. PI. xix. Head short and thick; upper central surface but
little depressed, not to say grooved ; the suborbital ridge being slightly elevated.
The occipito-temporal ridge is thicker, and hence a little more conspicuous.
Snout rounded, nostrils terminal. Mouth wide, upper jaw emarginated. Tym-
panum and parotids of moderate size. Limbs rather short and stout. First
finger much longer than the second. A large metacarpal disk. Toes semipal-
mated. Two metatarsal tubercles, a very large and a very small one. No
membranous fold at the inner lower edge of the tarsus. Papillae of medium
size upon the back. Inferior surface, with rather small and crowded granular
warts. Above dark brown, with numerous lines of yellow. A dorsal yellowish
vitta running the whole length of the body. Transverse blotches of black upon
the thighs and fore arms. Beneath ochraceus.

The affinities of this species are intermediate between B. americaims and B.
lentiginoses. Its geographic range appears to be New Mexico, having so far
been found in the province of Sonora, and in the San Francisco mountains.

4. Bufo cognatus, Say, in Long's Exped. to Rocky Mts. ii, 1823, 190. —
Holbr. N. Amer. Herp. v. 1842, 21. PI. v. — B. and G. in Marcy's Expl. Red

A very characteristic species in the structure of the upper surface of head.
Found in the territory of Nebraska, and southwards as far as the province of
Coahuila, Mex.

5. Bufo speciosus, Girard. — Head moderate ; its upper surface smooth and
even, or with slight traces of ridges or carinae. Snout subtruncated and rounded;
nostrils subterminal. Mouth large, upper jaw slightly emarginated. Tongue

small, elongate, posteriorly free for the fourth of its length. A subgulav vocal
bladder. Tympanum of medium size. Parotids subovoid, of stoutish appear-
ance. Limbs of moderate development. First finger much longer than the
second, which is equal to the fourth. A large subcircular metacarpal disk.
Toes semipalmated. Two metatarsal spade-shaped processes, the innermost
being much the largest. A membranous fold at the inner lower margin of tar-
sus. Skin above covered with papillae of moderate development, and with small
warts beneath. Color above greenish brown, maculated: no dorsal lighter
vitta. Beneath, greenish or yellowish white, unicolor.

Allied to B. woodhousii, differing, however, in the form and development of
the metatarsal processes. It appears to inhabit the valley of the Rio Bravo
(Rio Grand del Norte), and to be not uncommon in the province of New Leon.

6. Bufo punctatus, B. and G. Acad. Nat. Sc. Philad. vi. 1852, 173.

A very marked species in the shape and structure of the head. Hitherto
found in the valley of the Devil's river (Rio San Pedro, of Rio Grande), and in
the province of Coahuila, Mex.

7. Bufo debilis, Girard. — Upper surface of head without any crest or ridge.
Snout rounded. Mouth moderate. Upper jaw emarginated. Tongue small.
Tympanum small. Parotids moderate and elongated. Limbs of moderate de-
velopment, femur shorter than tibia. First finger longer than the second. A
large metacarpal disk. Toes slightly united at base by a web. Two metatar-
sal processes. No membranous fold at the inner lower margin of the tarsus.
Skin above pustulous; pustules of moderate development; warts beneath
very small. Color above brownish yellow, spotted. No dorsal lighter vitta.
Beneath of a uniform soiled yellow.

Allied to B. speciosus ; found in the lower part of the valley of the Rio
Bravo ^Rio Grande del Norte), and in the province of Tamaulipas.

8. Bufo nebulifer, Girard — Bufo granulosus, B. and G. (non Spix). Proc.
Acad. Nat. Sc. Philad. vi. 1852, 173.

This species is strongly suggestive of B. mariuus, Schn. (B. agna Daud) ; it
is, however, easily distinguished from it upon a comparison of individuals of
both species. It inhabits Texas, the valley of the Rio Bravo (Rio Grande del
Norte), the provinces of Tamaulipas and New Leon, Mexico.

9. Bufo columbiensis, B. and G. Proc. Acad. Nat. Sc. Philad. vi. 1853,
378.

This is possibly the largest species of North American toads; it is common in
the valley of the Columbia River, Oregon Territory, where it was first observed
by the naturalists of the U. S. Exploring Expedition under Capt. C. Wilkes.

10. Bufo boreas, B. and G. Proc. Acad. Nat. Philad. vi. 1852, 311.

So far the most northern bufonid ; it is not uncommon about Puget Sound,
where it was collected many years ago by the naturalists of the U. S. Explor-
ing Expedition.

11. Bufo halophila, B. and G. Proc. Acad. Nat. Sc. Philada. vi. 1853,
311.

Since this species was first described an adult individual has been secured,
which has enabled me to give the following diagnosis :

Upper surface of head without either crests or grooves. Skin thick and adhering
to skull. Snout rounded. Parotids of medium size. Ryes moderate. Tym-
panum small. Tongue lanceolated, bro.idest posteriorly. Upper jaw emargi-
nated. Inner finger longer than the second. Two metacarpal disks. A mem-
branous fold along the tarsus. Toes semipalmated ; two metatarsal tubercles.
A narrow yellowish dorsal vitta. Ground color greenish yellow, with nume-
rous black spots and dots, distributed all over the upper parts and sides of body,
head and limbs. Beneath unicolor of a dingy yellow.

Inhabits the western coast, frequenting the sea margin ; hitherto observed
only in California.

12. Bufo quercinus, Holbr. N. Amer. Herp. v. 1842, 13. PI. iii.

This quite small species appears to be restricted to very narrow geographical
limits, having so far been found only in the neighborhood of Charleston, S. C.

13. Bufo insidior, Girard. — Upper surface of head plane and smooth. Snout
subacute, protruding. Mouth moderate, upper jaw slightly emarginated.
Tongue elongated, tapering towards both ends. Tympanum inconspicuous.
Parotids large and elongated, situated obliquely upon the shoulder. Limbs
moderate. First finger equal to the second in length. A metacarpal disk, and
a tubercle. Toes slightly webbed at base. Two metatarsal tubercles. Skin
papillous above, warty beneath. Above of a bluish slate hue, with black
markings. Beneath unicolor, dingy yellow.

Small specimens, perhaps immature, were collected in Chihuahua by Dr.
Thos. H. Webb, attached to Comm. Bartlett's party in the survey of the U.
S. and Mex. boundary line.

1841, 743.

Found in South Carolina, Georgia, Florida, Louisiana and Mississippi.

15. Engystoma rugosum, Dum. and B. Erp. gen. viii., 1841, 744.

Said to occur in the same regions as the preceding species. Have never ob-
served it, and therefore cannot endorse it as a North American species.

From the Trustees of the New York State Library, dated Albany,

From the American Philosophical Society, dated August 20, 1854,
severally acknowledging the receipt of recent publications of the
Academy.

From Dr. M. H. Houston, dated Wheeling, Va., May 22d, 1854,
presenting the Indian remains deposited in the Cabinet by Mr. Ellet,
through Dr. C. D. Meigs, May 16th, 1854.

Dr. Hallowell presented for publication in the Proceedings, two papers,
entitled respectively, " Descriptions of New Reptiles from California ;"
and " On a genus and species of Serpent from Honduras, presumed to
be new," both of which were referred to Dr. Leidy, Dr. Le Conte, and
Col. McCall.

Dr. Leidy stated that while examining some fossils he had accidentally in-
spected the fragment of lower jaw, supposed by Harlan to belong to an extinct
species of hog, the Sus americanns ; and which Prof. Owen, after an examination,
had considered as a new genus, Harlavus, allied to the tapiroid pachyderms,
when it immediately occurred to him that it belonged neither to a suiline nor a
tapiroid animal, but to a true ruminant, and this, the Bison latifrons.

The form of the fragment of jaw is the same as the corresponding portion in
the ox, and its robustness is in relation to the size and strength of the head of
Bison latifrons.

The fossil belonged to a very old individual, as indicated by the production of
large fangs to the teeth, and the almost entire removal of the enamelled crown
by trituration.

The first of the series of true molars in the specimen exhibits two fangs of
dentine united by an isthmus of cementum, (see plate vi. accompanying Owen's
memoir, in vol. i. new series, of the Journal of this Academy.)

In the second true molar a line of enamel yet borders the crown. The little
prominence in the centre of the dentinal space of the anterior lobe is the rem-
nant of the crescentic enamel island. The middle of the three folds on the outer
side, which misled Prof. Owen to suspect an affinity of the animal to Toxodon,
is nothing more than the remains of the robust accessory column of the molars
of Bison latifrons t as may be seen by comparing the specimens, or the figures in
Owen's plate, with the corresponding part in the figures 6 and 7 of the last molar
in plate ii. of my " Memoir on the Extinct Species of American Ox."

The last molar of Bison latifrofis, indicated in the figures just mentioned, not
only exactly fits the corresponding space in the fragment of jaw, but the remain-
ing portion of tooth in the latter is of the same form and size as the correspond-
ing portion of the entire tooth.

If these views be considered as correct, then the Sus americanns, or Harlanus
america?ius, ceases to be a distinct animal, and the fossil in question becomes a
portion of Bison latifrons.

In further confirmation of these facts, a portion of a humerus and a tibia,
mentioned in Prof. Owen's paper, and an atlas and a metacarpal bone were dis-
covered by Mr. Couper, with the [fragment of jaw, and these had previously
been referred to Bison latifrons in my memoir above referred to.

90

[June,

Dr. Leidy next called attention to several fossils indicating new species of
extinct mammalia.

The first was the crown of a molar tooth discovered by Captain Bowman,
U. S. A., in the sands of Ashley river, S. C. It most resembles the left lower
penultimate molar of the bear, but the triturating surface is more generally
level, and presents less disposition to the formation of cusps. The specimen
measures 24 m.m. antero-posteriorly, and 17 m.m. transversely. For the genus
and species supposed to be indicated by the specimen the name of Aretodus pris-
tinus was proposed.

The other fossils consisted of two specimens loaned by Prof. Hall, of Albany,
and constitute part of the collection made by Messrs. Meek and Hayden, during
an expedition to Nebraska Territory in the summer of 1853. They were found
on Bijou Hill, east of the Missouri River, in a tertiary formation surmounting
cretaceous beds.

One of the specimens is an inferior molar of a solipedal animal, apparently
intermediate to Equus and Anchitherium, the enamel folding upon the triturating
surface being less complex than in the former, and greater than in the latter.
It appears to have had an envelope of crusta petrosa as in the horse, though
nearly all removed in the specimen. In size it is relatively long compared to
the corresponding teeth of A7ichitheriumi but is short compared to those of
Equus. Its antero-posterior measurement in 17 m.m. For the genus and species
the name of Hippodon speciosus was proposed.

The remaining specimen is the fragment of a lower jaw, containing a last pre-
molar and the first true molar of a small ruminant allied to the Musks. The
last premolar on the triturating surface presents a series of five folds projecting
inwardly. Its measurement antero-posteriorly is 8 m.m. The inner side of the
true molar is nearly as plain as in those of Pceb rot her item. Its measurement
antero-posteriorly is also 8 m.m. For the genus and species the name of Mery-
codus necatus was proposed.

Dr. Ruschenberger in the Chair.

A letter was read from Dr. W. P. Gibbons, dated San Francisco, May
16, 1854, transmitting the specimens of viviparous fishes acknowledged
this evening; also a paper intended for publication in the Proceed-
ings, entitled, u Descriptions of four new species of Viviparous Fishes
from Sacramento River and the Bay of San Francisco. Read before
the California Academy of Natural Sciences, May 15th, 1854; by Wm.
P. Gibbons, M. D."

Referred to Dr. Le Conte, Dr. Leidy, and Dr. Hallowell.

Dr. Hallowell presented a paper for publication in the Proceedings,
entitled, " Remarks on the Geographical distribution of Reptiles,
with descriptions of several species supposed to be new, and corrections
of former papers ;" which was referred to Dr. Leidy, Dr. Da Costa, and
Dr. Le Conte.

Dr. Da Costa directed the attention of the Academy to a new process which
he had lately employed in making minute injections. In order to insure a greater
rotundity and distinctness of the vessels than is usually obtained, he performed
a series of experiments with solid substances dissolved in ether, and as evidence
of the results he submitted several specimens to the inspection of the members.
The substances selected on account of their ready solubility were the resins, and
of these the sandarach and the Damarra copal were found to answer best. One
ounce of the resin was dissolved in about three ounces, or if mucous membranes
were to be injected, in about four ounces of ether. This was then filtered, and
enough finely ground yellow or red paint added to give to the injecting mass the

1854.] 91

requisite color. Judging from the equal distinctness of the vessels in some of
Prof. Hyrtl's preparations in his possession, he was led to believe that it is on a
similar principle that these beautiful injections are made, except that turpentine
is probably used as a solvent instead of ether. He was, however, not able to
speak positively on this subject, since the injecting material used by Prof. Hyrtl
has never been disclosed. The advantage of using ether for injections, as first
directed by Dr. Goddard, instead of turpentine, is that preparations in which
ether has been used are always more uniformly and more minutely injected ; and
by dissolving solid substances in it, Dr. Da Costa believed that equal distinctness,
with perhaps greater minuteness than is even afforded in the preparations of
Prof. Hyrtl, may be obtained.

Descriptions of new Reptiles from California.
By Edward Hallowell, M. D.

CHELONIANS.

Emys nigra, nob.

Sp. Char. — Shell oblong-ovate, slightly compressed at the sides and emargi-
nate, but not distinctly serrated posteriorly; latero-posterior margins of carapax
everted; nuchal plate narrow, truncate anteriorly, broader posteriorly ; 24 mar-
ginal plates, the two posterior more or less quadrilateral, the two adjoining pen-
tagonal ; color blackish above, the upper part of head and neck presenting
numerous very small yellow spots upon a black ground ; anterior extremities
with a tinge of yellow ; under jaw and throat yellow, with dark colored mark-
ings ; plastron yellow in the middle, with large blotches of black or dark brown
at the sides, and anteriorly and posteriorly ; under surface of tail and extremities
blackish; tail of moderate length.

92 [June,

Dimensions. — Length of head 1 inch ; breadth f ; length of carapax 6£ inches,
measured along curvature superiorly ; breadth at middle 5| inches ; of tail 2§.

Habitat. — Posa Creek, Lower California, where it occurs in great numbers.

Gen. obs. — This species resembles none ol the North American Emydes with
which 1 am acquainted. Its dark color puts one in mind of, but is not so jet a
black as that of Sternothaerus niger of Madagascar.

SAURIANS.

Dipso-saurtjs, Hallowell.

Gen. char. — Head triangular, covered above and in front with tubercles ; nos-
trils latero-superior, opening in a single scale ; rostral plate veitical, triangular;
jaws margined each with a series of smooth quadrilateral plates ; tympanum
visible, depressed ; upper part of body covered with carinated scales, more or
less rounded posteriorly, arranged in oblique rows ; a row of scales much larger
than the rest along the dorsal line, and much more strongly carinated, forming
a slight dorsal crest; a gular fold ; scales of abdomen quadrangular, smooth ;
femoral pores ; tail covered with transverse rows of verticillate and carinated
scales*

DlPSO-SAURUS DORSALIS.

Sy?i. — Crotaphytus dorsalis, Baird and Girard. Proceed. Acad. Nat. Sc. 1852,
p. 126.

Coloration. — Body presenting numerous lines of red upon the sides, with
blotches of the same color over the shoulders, the intervening spaces numerous
white spots; upper surface and sides of tail marked with red spots arranged in
transverse rows ; upper surface of extremities with red ; throat, abdomen, under
surface of extremities and tail white. The coloration, as described by Profs.
Baird and Girard, appears to be taken from younger specimens, one such before
me corresponding with it precisely.

Dimensions. — Length of head 7 lines; breadth 7 ; length of head, neck and
body to vent, 8 inches, (Fr.) ; of tail lh inch.; anterior extremities 1£ inch. ;
posterior 3 inches to extremity of nail of longest toe.

Habitat — Desert of the Colorado, to which it appears to be confined. The
smaller specimen from near Fort Yuma, the large one found in the desert be-
tween Rum River and the Tejon Pass, (pronounced Tahon ;) a country without
water, not sandy, but arid, bearing artemisia, &c.

Gen. remarks. — This animal differs from Crotaphytus (Holbrook) in having
the upper part of the body covered with quadrangular scales, instead of granula-
tions, and the larger row of carinated dorsal scales giving rise to a slight crest,
no trace of which exists in Crotaphytus, from Leiolepis in having tubercles, and
not plates, upon the head and from Homalo-saurus in the form of the marginal
plates of the upper jaw.

Uro-saurus, Hallowell,

Gen. char. — Body very slender, which, as well as the head, is much depressed;
scales upon the back much larger than those upon the sides, and strongly cari-
nated ; nostrils superior in a single scale; head covered with plates ; aural aper-
tures very distinct ; a gular fold ; extremities slender; toes 5—5 ; tail very long
and tapering, verticillate ; femoral pores, but no anal ones.

Uro-saurus graciosus, nob.

Sp. char. — Head yellow, with a few browrnish marks; seven longitudinal rows
of scales upon the back very distinctly carinated. Color of body yellowish,
mixed with brownish and black spots ; extremities yellowish, with dark colored
transverse bands ; tail of same color above as body ; under surface silvery white,
with blackish spots; eleven femoral pores.

Dimensions. — Length of head 5-8ths inch; greatest breadth f inch; length
of head, neck and body to vent, If inch j of anterior extremities to extremity of

1854.] 93

longest toe 6-8ths inch ; of posterior to extremity of longest toe Jf inch ; of tail
4£ inches; total length.

Habitat. — Lower California.

Gen. Remarks. — The contrast between the large carinated scales upon the
back, and the small ones upon the sides resembling granulations, is very striking ;
the long and slender tail also is remarkable. In these respects Uro-saurus is
allied to Tachydromus, but the plates upon the head are very different.

SCELOPORUS, Wiegmann.'

ScELOPORUS MAGISTER, nob.

Sp. char. — Larger than any known species of Sceloporus, and remarkable for
its large and strongly carinated scales, which are very much denticulated poste-
riorly ; anterior margin of aural apertures strongly denticulated ; upper part of
head, body and extremities and tail straw color, without spots or blotches ; a
black triangular blotch upon each side of the neck, in front of the shoulder, the
base below ; two large bluish green blotches upon the abdomen, one on each side
and one upon the neck ; the rest of the under surface light straw color ; tail long,
very thick at base, tapering near the point ; twelve femoral pores on each side.

Dimensions. — Length of head, neck and body to vent, 4 6-8ths inches; great-
est breadth of head 1£ inch; length of head If inch ; of tail l-5th inch ; of anterior
extremities l£ inch ; of anterior foot to extremity of longest toe 1 inch ; of pos-
terior extremities 1 6-8ths inch; of foot to extremity of longest toe If inch :
total length 9 6-8ths inches.

Habitat. — Near Fort Yuma, at junction of Colorado and Gila, also nearTuson
in Sonora, upon a rocky soil.

Gen. remarks.— This species is remarkable for its large size and greatly deve-
loped spines. It is a much larger animal than the spinosus of Wiegmann, and
wants the quadruple series of dark colored spots that exist in that animal.
The posterior margins of the scales are strongly denticulated, which is not the
case in spinosus, one of the characters of which is " squamis paucidentatis."
From horridus, Wieg. it differs in coloration, arrangement of plates upon the head,
and in the number of femoral pores, which in the latter are 4 — 5.

Sceloporus bi-seriatus, nob.

Sp. char. — Scales of the back much larger than those upon the sides. Five
frontal plates in two rows ; the middle of the anterior row largest ; four inter-
nasals ; two very small plates between the anterior row and rostral ; two vertical
plates ; one large plate on each side of the occipital, and two in front of them;
posterior border of scales not denticulated. A narrow brownish vitta across the
head near the middle of the superciliary plates ; coloration of head resembling
that of undulatus ; light ash grey above, with a double row of dark-colored spots
upon the back on each side of the dorsal line, extending a short distance upon
the tail ; extremities ash colored above, banded with black ; under surface
silvery grey, with two blue blotches, one on each side of the abdomen, and a
blue blotch upon the chin ; 20 femoral pores.

Dimensions. — Length of head, neck and body to vent, 3 inches: of tail 4£
inches ; length of anterior extremities 5-8ths inch ; of foot anteriorly to extremity
of longest toe 5-8ths inch ; of posterior extremity 1 inch ; of foot posteriorly to
extremity of longest toe 1 inch ; total length 7£ inches.

Habitat. — Borders of El Paso Creek and in Tejon Valley. Constantly climb-
ing up trees, when scared, to a distance of twenty or thirty feet, running along
the ground and up the trees very quickly.

Gen. remarks. — Wants the undulating lines or bars of undulatus, these being
replaced by the spots above described; the scales upon the sides are also
much smaller than those of undulatus. This species resembles very closely
the variabilis of Wiegmann, and is probably the same, notwithstanding cer-
tain differences in the description. In the absence of a good drawing, or authen-
ticated specimen, we cannot pronounce, positively, whether they be the same
or not, although inclined to the former opinion. Thus the head, according to

94 [June,

Wiegmann, is unicolor ; and the plates upon the head cannot be said to
he ruguloso carinatis, for they are for the most part smooth in bi-seriatus.
It wants the white lateral line beneath the spots which is observed in scalaris,
Wiegmann. The arrangement of the plates upon the head appears to characterize
this species very well, being uniform, with unimportant exceptions, in all the
specimens brought by Dr. Heermann.

Var. A. azureus. — Body uniformly blue above, mingled with brown, the
the blue color predominating; on the sides greenish with a metallic lustre ; head
brownish above ; two large blue blotches upon abdomen, one on each side ; rest
of under surface silvery white with bluish tints, especially about the chin ; scales
large and strongly carinated, not denticulated posteriorly; tail stout at the base,
much less tapering than in bi-seriatus; the plates of the head correspond pre-
cisely with those of the latter animal.

Dimensions*— Length of head, neck and body to vent, 3 2-8ths inches ; of tail
3 5-Sths inches ; of anterior extremities 1 inch ; of anterior foot to extremity of
longest toe 6-8ths inch ; of posterior foot to extremity of longest toe 1 2-8ths
inch ; total length 6| inches.

Habitat. — Associated with bi-seriatus.

Var. B. variegatus. — Body light ash color, with transverse brownish bands
and markings coalescing with each other, so as to give the whole a marbled
appearance ; head above ash color mingled with brown ; extremities ash color,
with transverse bands of brown ; under surface silvery grey without bluish spots
or blotches ; 17 femoral pores, remarkably large ; tail stout, thick at the base.

Dimensions. — Length of head neck and body 4h inches ; greatest breadth of
head 1 inch ; length 1 inch ; tail mutilated, circumference at base 1 2-8ths inch ;
length of anterior extremities If inch ; of loot to extremity of longest toe f inch ;
of posterior extremity 2£ inches ; of foot, posteriorly, to extremity of longest toe
1 inch.

Habitat. — Same.

CNEMIDOPHORUS, Dum. and Bib.

Gen. Char. — Nostrils in the nasal plate near its posterior border ; two supero-
nasals ; palate without teeth, with a shallow, triangular notch, posteriorly ;
scales smooth. (Dum. and Bibron.)

Cnemidophorus undtjlatus,* nob.

Sp. char. — Body of moderate size ; tail very long ; head brownish above ; upper
part of body with three or four longitudinal bands of black with irregular mar-
gins ; interspaces yellowish, with a tinge of red in some specimens ; sides mar-
gined with black and white or light yellow ; tail black and light yellow, present-
ing numerous transverse rows of rhomboidal carinated scales ; upper part of
extremities same color as sides of body; under surface silvery grey, with a
number of minute black spots upon the abdomen, throat and chin ; tail round,
moderately thick at base, tapering to a point ; 20 pores very distinct ; 8 rows
scales upon the abdomen.

Dimensions. — Length of head 1 inch ; greatest breadth posteriorly half an inch ;
of head, neck and body 3k inches ; of anterior extremities % inch ; of foot to ex-
tremity of longest toe half an inch; of posterior extremities 1£ inch ; of foot to
extremity of longest toe 1 inch ; of tail 7£ inches ; total length 111 inches.

Habitat. — Near Fort Yuma, in San Joachim Valley.

Gen. observ. — Cnemidophorus perplexus, according to Profs. Baird and Girard,
has seven longitudinal yellowish lines along the back ; in all the specimens above
described, five in number, there are but four. Profs. Baird and Girard state that
in some specimens of Cnemidophorus tigris, " four longitudinal yellow stripes
may be seen extending from the occiput to the base of the tail, and occasionally
a little distance on the latter. In the young state the black patches predominate,
unite, and form as it were the ground color, and the yellow constitutes irregular
small spots." — Vide Sta?isbury's Report, Appendix C. p. 339.

•From the undulating longitudinal dark lines along the back.

1854.] 95

The total length of Say's Ameiva tesselata is 1 foot, tail 8J inches, — in
this respect corresponding very well with the above, but none of the specimens
present the tesselated appearance described by Say, the «' transverse lines
dividing the whole surface in a tesselated manner."

Eumeces, Wiegmann,

Sp. char. — Two supero-nasals contiguous ; internasal much more extended in
the lateral than antero-posterior direction, its internal margins in contact with
the anterior frenal ; two fronto-nasal, contiguous, lateral border in contact with
the posterior frenal ; frontal hexagonal, elongated, broader anteriorly ; fronto-
parietal rhomboidal, placed obliquely ; inter-parietal broad, with an acute angle
in front, passing in between the fronto-parietals ; parietals oblong, quadrilateral ;
four supra-orbitals ; a small naso-frenal : an anterior and posterior frenal, the
latter much larger ; twelve rows of smooth hexagonal scales upon the back, be-
ginning with those marked by the lateral vitta.

Color. — Shining black or brown above, with four bluish vittae, the two in-
ternal broader than the others, commencing about midway upon the sides of the
head immediately over the eyes, and extending along the back and terminating
upon the tail ; the lateral ones commence at the anterior margin of the orbit,
and passing beneath it, extend upon the sides and are lost upon the tail ; chin
and throat whitish ; abdomen and under part of tail slate color ; under surface of
extremities whitish.

Dimensions. — Length of head f inch ; breadth \ inch ; length of body and tail
4? inches; of tail 2 3-8ths inches; of anterior extremities £ inch; of posterior
| inch.

Habitat. — Lower California, near Mohave River, and in San Bernardino Valley.

OPHIDIANS.

Rhinostoma occipitale, nob.

Char. — Teeth of equal length, posterior ones not channelled ; head depressed,
eyes small ; a rostral, two anterior and two posterior frontals; one anterior and
two posterior oculars; a vertical ; two occipitals ; a small frenal ; nostrils in a
single plate ; seven superior labials, the eye resting on the third and fourth.
Abdom. scuta, 158 ; subcaud. 34.

Coloration. — Milk white above with 41 transverse black bands, including
seven upon tail and one upon posterior part of head ; six complete rings upon
tail ; throat and abdomen white ; under part of tail white, with transverse bands
continuous with those upon back of tail ; 15 rows of smooth quadrangular scales.

Dimensions — Length of head 4 lines, breadth 2£ lines; of body 9 inches 9
lines; of tail, 1 inch 7 lines; total length, 9 inches.

Hab. — Mohave Desert.

Gen. Remarks, — This serpent resembles no other as yet figured in N. Ame-
rica, and is therefore easily recognized. In the genus Sonora of Prof. Baird and
Girard, there are, according to them, three postoculars, and two nasal plates on
each side with the nostril between them. In Sonora semiannulata there are
twenty-five transverse black bands upon the body, and six complete rings upon
the tail. The rings in Col. (Zacholus) zonatus of Blainville completely sur-
round the body. The nostrils, according to Blainville, open between two plates,
but Wagler has them each in a single plate, " in medio scutelli sitis," in his defi-
nition of Zacholus. Wagler, however, cites Col. Riccioli, Metaxa Serp. Rom.
as appearing to belong to this genus, " scheint als gattung zu gehoren," but C.
Bonaparte represents the nostrils as placed in the commissure between two scuta
M gli narici sono situate alia eommissura di duo scutelli nasali." Blainville
represents two black half rings upon the head. Zacholus zonatus is probably
allied to Coronella balteata.

Crotalus cerastes, nob.
Sp. Char. — Head covered with polygonal tubercles, larger in front, the latter
in three rows; two small quadrangular plates on each side, between the nostril
and the vertical rostral ; two quadrangular internasals ; external border of supra-

96 [June,

ciliary plates developed, so as to present two horn-like processes, one on each
side of the head at their middle; nostrils small; pits between the eyes and nos-
trils large ; twenty rows of carinated scales, the inferior rows near the abdomen
smooth; body slender, much compressed; tail very short, with three or four
rattles.

Coloration. — Head ash color above, a black band running from the posterior
margin of the orbit to within a line of the occiput ; a series of forty-one transverse
brownish bands, yellow in the centre, along the back; general color of animal
above light yellow; several transverse bands upon the tail ; under surface light
yellow, slightly clouded with spots near the external margin of the abdomen;
abdom. scut. 146 ; two rows of bifid post-abdom. scutell. ; 14 single caudal scuta ;
three inferior rows bifid.

Dimensions. — Length of head 5 lines; greatest breadth 4 lines; length of body
8 and 3-8th inches; of tail, | ; total length 9| inches.

Hab — Borders of the Mohave river, and in the desert of the Mohave, — always
in the dry sandy soil, with no vegetation whatever. Maximum size one foot
and a half; occurs in large numbers, and is also seen in the Desert of the Colo-
rado, but is much less abundant, Dr. Heermann not having observed it ihere.
The river Mohave spreads itself out in the desert and there loses itself, and upon
the floating sand hills near it these animals are found. The Crolalus Lecontii
is never seen with them. The Mohave empties into a salt lake about 15 miles
in extent.

Gen. Remarks. — I supposed that this animal might be the young of Crotalus
Lecontii, but Dr. Heermann informs me that the Lecontii is never found with
it, and that it never attains to more than a foot and a half in length, and always
presents the horn-like processes above described. It would appear to be the
representative of the Vipera Cerastes of Africa, and is found, like that serpent,
in desert and sandy regions, and is also slow and sluggish in its movements.
The genus Cerastes, proposed by Wagler and adopted by Dumeril and Bibron, it
would appear should be dropped and Vipera substituted.

BATRACHIANS.

Rana nigricans, nob.

Sp, char. — Remarkable for its size ; color uniform, dark brown, with numerous
small black spots, and large blotches interspersed over the surface ; sides some-
what lighter, marked with black; anterior extremities dark brown, or ash color
above, blotched with black ; posterior of same color, with numerous transverse
black bands; chin, throat and abdomen straw color, shaded with brown; under
surface of extremities yellowish, marked with black.

Dimensions. — Length of head, neck and body, 4£ inches; greatest breadth of
head, If inches; length of anterior extremities, 1| inches: of foot anteriorly to
extremity of longest toe, 1 inch; of posterior extremity, 5 inches; length of hind
foot, If inches ; of foot posteriorly to distal end of longest toe, 2| inches.

Hab. — El Paso Creek.

Gen. Observations. — This species is remarkable for the great length of its
posterior extremities; allied to Rana Draytoni, Baird and Girard, but the
posterior extremities appear to be longer.

Hyla nebulosa, nob.

Sp. char. — Uniform light grey upon the upper part of the body and sides ;
snout light ash ; a considerable number of dark colored subcircular spots about
a line in diameter, scattered over the upper part of the body and upon the sides ;
extremities ash color above, with greyish spots; abdomen greenish yellow; chin
light yellow; under surface of extremities orange colored; abdomen and under
surface of extremities granulated.

Dimensions. — Length of head, neck and body, If inches; greatest breadth of
head, | inch; length of anterior extremities, If inches; of posterior extremities
2 and 3-8th inches to extremity of longest toe.

Hab. — Tejon Pass.

1854.] 97

Gen. Remarks. — Is a much smaller animal than Hyla versicolor, and the mark-
ings are very different. The back is much less abundantly covered with warts,
and the superciliary ridges which are so much developed in versicolor, are but
slightly so in this species. The extremities are much more slender in the latter,
and the tibia is of nearly equal length with the thigh, but in versicolor it is
about a line shorter.

Hyla scapularis, nob.

Var. hypochondriaca.

Char.—Oi a uniform pale olive, color above without spots, paler toward the
sides; numerous small, elevated smooth points upon the surface, resembling
tubercles; upper surface of extremities pale olive; a narrow dark colored vitta,
extending from the anterior margin of the eye to the snout; another much
broader from the posterior margin of the eye to the shoulder ; margin of upper
jaw of same color as the vitta ; posterior part of abdomen and under surface of
extremities orange colored ; chin and throat whitish ; abdomen thickly granulated.

Dimensions. — Length of head and body, \h inches; of head f ; breadth f ;
length of anterior extremities, f ; of posterior, If.

Hab — Tejon Pass.

Gen. Remarks. — It will be observed that it wants the squalus toothed mark
upon the head, and the markings upon the back, which belong to scapularis.

The specimens above described, with numerous others already known, and a
large number of rare fishes, birds and plants, and many insects, were collected
by Dr. Heermann, Naturalist to the Government Expedition for the exploration
of a route for the Pacific Railroad, and afford the best evidence of the zeal and
untiring industry of our esteemed fellow member. Through his efforts in great
part the Herpetology of California is now almost, if not quite, as well known as
that of Pennsylvania.

MICROPHIS.

Char. — Head of moderate size, short, depressed in the middle, covered
with nine plates ; snout rounded ; nostrils between the nasal and anterior frontal
plates ; a frenal; one antocular ; two posterior oculars ; seven superior labials,
the eye resting on the third and fourth; eyes of moderate size, pupil round;
supraciliary plate not projecting over the eye ; tail of moderate length.

Microphis quinqueliniatus, nob.

Sp. char. — Head, body and tail above ash color ; five dark blue stripes ex-
tending from the occiput to the base of the tail, the three intermediate ones
broader than the lateral; the other stripes prolonged upon the tail, the middle
one to near its extremity ; 17 rows of smooth quadrangular scales ; 170 abdom.
scuta; two bifid preabdom.; 33 subcaudal.

Dimensions. — Length of head 6-8ths inch; breadth posteriorly 4-8ths inch ;
length of body 17 inches ; of tail 2 inches 5-8ths ; circumference 1 inch 3-8ths ;
total length 1 foot 8 inch 3-8ths.

Habitat. — Honduras, South America. Two specimens presented to Museum
of the Academy, by Dr. Woodhouse.

Gen. Remarks. — This serpent has the general characters of Coronella,but the
nostrils open between the anterior frontal and nasal plates, insiead of the nasal
and internasal, the two being fused into one plate. We have, therefore, pro-
posed for it the generic name given above, although not disposed to attach much
importance to minor considerations of this kind in the determination of genera.

this genus from the same locality, described by me some years ago as Plestiodon
Harlani. It is a much larger animal and it differs from the present species
greatly in its coloring, being uniformly yellowish brown above with distinct
bars of dark blown upon the sides. The scales in Harlani are tricarinate. I
have not been able to discover pterygoid teeth in either of these animals.

Fam. VIPERIDtE.

Gen. Brachycranion, Hallowell.

Gen. char. — Head short and thick, covered with seven plates, exclusive of the
rostral, viz., one pair of frontal, a vertical, two supra-orbitar, and two occipitals,
one ant-orbitar and one post-orbitar ; margin of orbit formed by supra-ocular, pos-
terior and anterior oculars, and superior margin of fourth labial plate. Subcaudal
plates single; palatal, but, with the exception of the fangs, no mandibular teeth.

Brachycranion corpulentum.

Sp. char. — Occipitals subquadrangular ; four supero-labials ; one large tempo-
ral plate immediately behind post-ocular ; scales smooth, quadrangular, 25 rows;
color shining black above, brownish beneath ; 182 abdominal scuta ; 25 sub-
caudal.

Dimensions. — Length of head i an inch, breadth 5 lines ; length of body 1 foot
6 inches ; of tail 2 inches ; circumference 1 inch 8 lines.

Habitat. — Liberia, W. coast of Africa. Presented by Dr. Ford to the Academy.

Gen. observ. — The vipers among venomous serpents are characterized chiefly
by the absence of forsettes behind the nostrils, and the presence of a double row
of plates under the tail. In the greater number, the head is covered with scales
as upon the body ; in others there are also plates of various forms, and irregularly
disposed, as in Vipera berus, while others have upon the head smooth and regu-
larly formed plates, like those of Coluber and the genus Sepedon of Merrem. In
others the subcaudal plates are bifid toward the anus, and single near the ex-
tremity of the tail, or alternately single and bifid as in Acanthophis.

Bungarus, a genus of Colubriform venomous serpents inhabiting Asia, has a
dorsal row of hexagonal scales larger than the others, with nine plates upon the
head and single plates under the tail. Elaps has nine plates upon the head, but
the plates under the tail are bifid. In the animal under consideration there are,
as above stated, but seven plates upon the head exclusive of the rostral, there
being but one pair of frontals (two in Elaps, Acanthophis and Bungarus) and
single plates under the tail. These characteristics, with the peculiar form of
the head and the presence of fangs, are such as to give it a distinct generic cha-
racter different from those of any of the serpents with which I am acquainted.
The appearance of Brachycranion corpulentum is very repulsive. Since the
above was written, I have observed in the work of Dr. Andrew Smith,* on the
Zoology of South Africa, the description and figure of a reptile which resembles
the one just described, to which the name Atractaspis Bibronii has been given.
The body in Atractaspis Bibronii is much more slender, is longer, but the tail
is shorter. The shape of the head in the figure is very different, giving one the
impression of a harmless serpent, as Dr. Smith at first supposed it to be, that of
the other induces at once a strong suspicion of its venomous character. There
are but twenty rows of scales in Bibronii, and the general color of the body and
tail is intermediate between blackish green and orange colored brown. The
fangs in Corpulentum also differ from those of Bibronii in their dimensions,
being not more than half the length of those in the figure of Bibronii. Like them,
they do not appear to be capable of complete erection. Upon the upper surface
of the tail in Corpulentum, along the median line near its middle, is a row of six
broad scales and four others near the tail, somewhat similar in appearance to
those upon the back in Dipsas.

Cham.eleo gracilis, Hallowell, Journal Acad. Nat. Sc. vol. viii. pi. 18. A
good species. It differs considerably in its general appearance from Chama?leo
dilepis of Leach, of which there are three specimens in the collection presented
by Dr. Henry A. Ford, of Liberia. One of these on being opened was found to
contain more than a dozen eggs. I thought at one time that possibly Ch. gra-
cilis might be the female of Ch. dilepis.

of head, 1 inch 5 lines ; of head and body 4 feet ; of tail 1 foot (Fr.) 2h inches.
Schlegel remarks that the mode of dentition in Dipsas cynodon is unique in the
genus, having one or more teeth much longer'than the rest at the posterior part
of the upper maxilla, others equally longer being found at the anterior extremity
of the inferior maxilla and of the palatal bone. It will be observed that a simi-
lar arrangement exists in Dipsas Blandingii, although the animals differ greatly
from each other. Triglophodon ? Dumeril. Prodromus, class, des Ophid.

Psammophis Phillipsii, nob.

Syn. Coluber Phillipsii, Proceed. Acad. Nat. Sc, vol. ii. p. 169.

A very well characterized species of Psammophis. Jaws very dilatable,
several teeth in the anterior part of the lower jaw longer than the others ; in the
upper maxilla on each side two long teeth posteriorly, and two near the middle;
teeth unequal ; four first followed apparently by an interval, then the two ante-
rior long ones ; scales lanceolate, smooth, intermediate ones more narrow.

Psammophis Phillipsii differs greatly from Psammophis moniliger of the Cape.
The two longitudinal rows of black spots are wanting in Phillipsii, and the
latter is a much larger animal ; 15 rows of scales.

CORONELLA TRIANGULARIS, nob.

Syn. Col. leevis, Proceed. Acad. Nat. Sc, vol. ii. p. 118.

17 rows of smooth scales, 21 in Coronella laevis. This animal has a general
resemblance to the Coronella laevis, (pi. 12, Amphibia, Fauna Pontica) but the
markings are very different, as is also the number of rows of scales. The tail
is also longer. It may be considered as the representative of the Coronella laevis
in Western Africa.

Leptophis smaragdina, Boie.

Sy?i. Dendrophis smaragdina, Schlegel. Leptophis gracilis, Hall. — Proc

terior frontals rather longer than the posterior ; nostrils between two plates;
one long and narrow loral on each side; one ant-orbitar, two posterior orbitars;
eight superior labials on the right side, nine on the left ; inferior margin of
orbit formed by the 4th and 5th on the right, and by the 5th and 6th on the
left side of the head ; posterior teeth not channelled. Since the above was
read, we have received Vol. vii. part 1, of the Herpetologie generale, ou histoire
naturelle complete des reptiles, par M. Dumeril, in which I observe that this
animal has been placed in the genus Leptophis by that eminent herpetologist.
This genus, as characterized by him, includes serpents with scales, sometimes
carinated and sometimes smooth, a conclusion which we ourselves had also
arrived at — the carination of the scales was added by Wagler. Proc Acad.
Nat. Sci., Dec, 1852, p. 203.

the others, and channelled anteriorly; 13 rows of scales, four upon the back
carinated, the marginal row near The abdomen larger than the others. Of this
species there are five specimens in the, collection of the Academy, three
from Dr. Savage, and two fully grown from Dr. Ford. These specimens illus-
trate very well the inconstancy of certain plates about the head in serpents.
In one the loral plates are entirely absent, the posterior frontal passing down to
join the superior labial plates ; in a second of the smaller specimens there are two
lorals on each side ; in a third there are two on one side (the left) and one on
the other ; in one of the larger specimens there are two on each side, and in the
other, two on the left and one on the right.* Wagler, in his definition of the
characters of the genus Dryophis states that there is no loral plate, the posterior
frontals passing down along the side of the head, and coming in contact with
tbe superior labials.

The genus Distichurus was based, very improperly, upon a single specimen ;
and the characters in that were not of sufficient importance to establish a genus.
The plates toward the extremity of the tail are not constantly single. In
one out of four specimens which we have, they are bifid. In Crotalus the plates
toward the extremity of the tail are sometimes bifid, and in Trigmocephalus
also.

Syn. Bufo cinereus. Proc. Acad. Nat. Sci., Vol. ii., p. 169. The name
cinereus has long been applied by Schneider, Daudin, Merrem and others to the
Bufo vulgaris of Europe. Bufo maculatus resembles somewhat Bufo pan-
therinus, but differs from it, according to the description of Dumeril and Bibron,
in the size of its tympanum, the breadth of which is considerably larger than
the length of the upper eyelid. The form and arrangement of the markings
differ greatly from those in the plate of Ruppel.

The Herpetology of Africa has as yet been but too imperfectly studied to
enable us to comprehend the geographical distribution of the reptiles of this vast
continent. The labors of Dr. Smith have left but little to be desired for the
illustration of the southern part of it, and Ruppell has given good dpscriptions
and drawings of a number of reptiles in N. Africa and Abyssinia. These, with
the great work on E<*ypt, and the late production of M. Bianconi, on the Natural
History of Madagascar, constitute the most reliable sources of information
appertaining to this subject. Let us hope that our own government will do for
the natural history of Western Africa what the English government has done
for that of the Southern portion of this great continent.

The reptiles common to both Northern and Western Africa, so far as we
know, are Agama colonorum, Chamasleo dilepis (bilobus) Kinixis belliana
Echidna arietans, Naja haj.,var. black, Vipera (cerastes) nasicornis, the genera

•This inconstancy is observed in other genera. In Hydrus pelamoides the
frenal shield observed by M. Schlegel was not present in four individuals, ex-
amined in the Straits of Malacca : in all Hydri the shields of the head are liable
to considerable individual varieties of form — (Cantor)* — "Hydrus bicolor —
Schneider — a frenal shield has been observed in some individuals, but it was
absent in that examined in the Straits of Malacca, nor does it exist in the speci-
mens in the Museum of the Asiatic Society." p. 135. "In Dryinus prasinus,
Reinwardt, there are two, sometimes three frenals on each side." p. 83.

Pachydactylus, and Onychocephalus, and Causus rhombeatus. The genera Uro-
mastyx and Stellio are found in Northern, but do not appear to exist in S. Africa.
The study of the geographical distribution of animals, and especially of reptiles,
presents many very remarkable facts. Some species appear to have a very
wide distribution, others a very local. The Cistudo Carolina, for example, is
found in almost every part of the United States, but Emys Muhlenbergii and
Testudo polyphemus have a very limited range, the one being known only in a
small portion of the Northern States and the other of the Southern. The spe-
cies of reptiles of the United States are entirely different from those of Europe,
but there are a number of genera common to both ; among these are Testudo,
-Emys, Coronella, Tropidonotus, Psammophis, Coluber, Rana, Bufo, Salamandra.

The genera Crotalus, Trigonocephaly or Elaps, all of which exist in the United
States, are not found in Europe, but the venomous serpents are replaced by the
viper, of which there are several species— none of which are found with us, the
serpent called viper in the U. States being a Heterodon, a very harmless animal.
The viper is common in England but does not exist in Ireland, neither does
the genus Bufo. Some genera are very limited in their distribution, being found
in certain localities and nowhere else. Thus Amphiuma and Siren are found
in the Southern States; Menopoma, in the West and South; Menobranchus, in
the Western waters of the United States; Phrynosoma in New Mexico and
Texas ; Anota, of which but two specimens have yet been discovered, and
Homalosaurus in the Desert of the Colorado; Holbrookia or Cophosaurus in Texas;
Platysaurus, in Southern Africa ; Hypochthoon in lllyria.

The species on the East and West Coast of South America differ almost en-
tirely from each other. The genus Proctotretus, comprising numerous species,
is found only in Peru. Other genera have a much wider distribution, but are con-
fined to certain large portions of the globe. Thus the Boas exist for the most
part in South America, the Pythons in Africa. According to Schlegel, no spe-
cies of serpent is found in all parts of the world, the Tortrix not an exception,
not being known in the United States. Gerrhosaurus is found in California, there
being but one species known in that State, but there are six species of the same
genus in Mexico, and six others, all described by Dr. Smith, exist at the Cape
of Good Hope.

My friend, Professor Baird, informs me that he has recently received, from
the We?tern portion of the United States, a specimen of Dipsas, a genus of ser-
pents not hitherto known to inhabit the United States. The genera Chamaeleo,
Euprepis, Eremias, Cordylus, Gecko, Hemydactylus, Ptyodactylus, Stenodac-
tylus, Phyllodactylus, Acanthodactylus, Zonurns, Varanus, are entirely unknown
in the United States, nor are there any true Lacertae. Among fresh water tor-
toises, the Emydes of the United States are very numerous, Prof. Holbrook having
figured as many as seventeen species ; they occur., also, in great numbers in In-
dia, twelve species having been described by Dumeril and Bibron, in their great
work on Reptiles. It is very remarkable, however, that but one species of
Emys, the Emys spengleri, of which we have the shell only in the Academy,
has been described as existing in the whole continent of Africa, whereas the
tortoises in the Southern portion of that country are numerous. Two species
of Sternothaerus are described as belonging to the island of Madagascar, the
niger and nigricans. We have the shell of one from Western Africa, which
probably belongs to the latter species. Among serpents the genus Tropidonotus
has a very wide range, being found more or less abundantly in almost every part
of the globe except Africa and Australia. The genus Trigonocephalus is not found
in Africa, but the vipers in that quarter of the globe are numerous, no less than
six species being described by Dr. Smith as inhabiting S. Africa, viz.: Echidna
arietans, atropos, atropoides, inornata, and Cerastes cornulus and ocellatus. To
these may be added the Vipera nasicofnis, or Natter Jack, which is found both
in Southern and Western Africa. Among the most remarkable of serpents are
those comprised in the genus Hydrophis. They are sea serpents, and <k inhabit
exclusively the inter-tropical latitudes of the Indian seas and of the great Pa-
cific Ocean."

It has been a matter of doubt whether these animals are poisonous or not; but

1854.] 103

Dr. Cantor, in a paper published in the Zoological Transactions of London,
asserts positively that they are, and recent observations made by Dr. Burnet
of Boston, have confirmed his statements. The tree snakes are not found in
Europe, neither are the Calamars, nor Lycodons and Heterodons. The Bungari
inhabit Ceylon, India, Bengal and Java. The Basilisk is found in Celebes, Am-
boina and the Phillipine Isles; Dilophyrus in India and the Malayan Peninsula.*
No species of Coronella is said to exist in New Holland (Schlegel.) Eryx is
found only in the East.

" Only one species of mammal is indigenous to the Gallapagos Islands, viz,, a
large and peculiar kind of mouse; but the number of lizards, tortoises and
snakes is so great that it may be called a land of reptiles. The variety indeed
of species is small, but the individuals of each are in great abundance. There
is a turtle, a large tortoise, (Testudo indicus,) four lizards, and about the same
number of snakes, but no frogs or toads. Belonging to the family Iguanidae, Bell,
are two species of Amblyrhynchus, one terrestrial, the -other marine ; the marine
species is extremely common on all the islands throughout the Archipelago. It
lives exclusively on the rocky sea beaches, and is never seen even ten yards
inland. The usual length is about a yard, but there are some even four feet long.
It is of a dirty black color, sluggish in its movements on the land, but when in
the water it swims with perfect ease and quickness by a serpentine movement
of its body and flattened tail, the legs during this time being motionless and
collapsed on its sides. Its limbs and strong claws are admirably adapted for
climbing over the rugged and fissured masses of lava which everywhere form
the coast. In such situations a group of six or seven of these hideous reptiles
may oftentimes be seen on the black rocks, a few feet above the sea, basking in
the sun with outstretched legs. Their stomachs, on being opened, are found
to be largely distended with minced seaweed, of a kind which grows at the
bottom of the sea, at some little distance from the coast. To obtain this the
lizards go out to sea in shoals. One of these animals was sunk in salt water
from the ship, with a heavy weight attached to it, and on being drawn up again,
after an hour, it was quite active and unharmed. It is not known by the inhabi-
tants where this animai lays its eggs ; a singular fact, considering its abundance,
and that the natives are well acquainted with the eggs of the terrestrial Amllyr-
hynehusf which is also herbivorous.'5 Lyell's Geology, p. 280; Darwin's
Journal, ch. xix. The Amblyrhynchus inhabits also S. America.

In the Island of Cuba are found the following genera: Emys (decussata and
rugosa, Shaw) Crocodilus (rhombifer and acutus,) Holotropis, Cyclura, Anolis,
Acanthophis, Chamaeleolis, Hemydactylus, Sphaeriodactylus, Gymnodactylus,
Amphisbaena, Typhlops,Tropidophis, Leionotui, Epicrates,Calamaria, Coluber,
Phyllobates, Trachycephalus, Bufo. The greater part of these genera are
unknown in the United States.

In Mexico there exist a number of very remarkable types, differing entirely
from those of our own country, viz., the genus Heloderma (horridum,) Cyclura
(denticulata and punctata,) Corythseolus (vittatus,) Chamaeleopsis (Hernandesii) ;
besides these are several species of genera belonging to our fauna, viz., Scelo-
porus (torquatus, formosus, spinosus, and others,) and six species of Gerrhonotus.f

The following remarks are made by Prof. Agassiz : "It has been already
stated that the present distribution of animals agrees with the distribution of
extinct types belonging to earlier geological periods, so that the laws which
regulate the geographical distribution of animals seem to have been the same at
all times, though modified in accordance with the successive changes which the
animal kingdom has undergone, from the earliest period of its creation to the
present day. The universal law is that all animals are circumscribed within
definite limits. There is not one species which is uniformly spread all over the
globe, either among the aquatic races or among the terrestrial ones. The special

f The most important facts in regard to the geographical distribution of rep-
tiles are contained in the great work of Dumeril and Bibron, by far the most
complete and useful on general herpetology that has yet been published.

adaptation of animals to certain districts is not merely limited to the individual
species. We observe a similar adaptation among genera, entire families, and even
whole classes. For instance, all Polypi, Medusae and Echinoderms, that is to say,
all Radiata, without exception, are aquatic. That large group of animals has not
a single representative upon any part of the surface of the globe, and during all
periods of the existence of our earth we find that they have been limited to that
liquid element. And they are not only aquatic, they are chiefly marine; but
exceedingly few of them are found in fresh waters. Among mollusca we find
almost the same adaptation ; their element also is the sea. The number of fresh
water species is small, compared with that of marine types ; and we find terres-
trial species in only one of these classes. In former periods also mollusca were
chiefly marine ; fluviatile and terrestrial types occurring only in more recent
periods." p. 195. The number of " marine species of fishes is far greater than
of the fresh water kinds. Among reptiles there are many which are aquatic,
either throughout life, or through the earlier period of their existence. But as if
animal life rose to higher organization as it leaves the ocean to inhabit dry land
or fresh waters, we find that the greater number of the aquatic reptiles are fiu-
vialile and but a few marine." The four great types, Radiata, Mollusca, Articu-
lataand Vertebrata were introduced at the beginning simultaneously. However,
the earliest representatives of all these great types were aquatic. We find in
the lowest beds which contain fossils, polypi, together with star fishes, bivalve
shells, univalve chambered shells, cases of worms and Crustacea, b?ing at least
representatives of seven of nine classes of invertebrate animals, if we are not al-
lowed to suppose that medusas existed also, and if insects were still wanting for
a time. But in addition to these, fishes among vertebrata are introduced, but
fishes only, all of which are exclusively marine. At a somewhat later period
insects come in. We find next reptiles in addition to fishes, the lower classes or
invertebrates, continuing to be represented through all subsequent epochs, but by
species changing gradually at each period, as all classes do after they have been
once introduced. The first representatives among reptiles are marine, next huge
terrestrial ones, some perhaps flying types, and with them, and perhaps even
before, the birds, allied to the wading tribes. Still later mammalia, beginning
again with marine and huge terrestrial types, followed by the higher quadru-
peds. And lastly, man, at the head of the creation in time as well as in emi-
nence, by structure, intelligence, and moral endowments." — Geographical Dis-
tribution of Animals, p. 197.

Description of four new species of Viviparous Fishes front Sacramento River, and
the Bay of San Francisco. Read before the California Academy of Natural
Sciences, May 15th, 1854. By W. P. Gibbons, M.D.

Hysterocarpus Traskii, Gibbons.

Body ovate, sub-compressed. Jaws with a single row of conical teeth.
Opercle and preopercle with scales, and with a membrane round the edge.
Dorsal fin commences opposite the pectoral, has seventeen strong curved
spines, the first short, the succeeding ones increasing regularly in length to the
sixth, which is the longest, and eleven articulated rays. The spinous rays lie
in a groove, which conceals the first two ; the remainder project an inch and a
quarter above the scales, and lapping by each other alternately form, in this
position, a double row.

Pectoial subquadrangular, with the lower edge rounded, and the first ray
short and subspinous. First ray of the ventrals shorter than the others, spinous
and curved.

First three rays of the anal fin with short, thick and curved spines, the middle
one largest.

Body arched, the radius of curvature being least along the anterior half of
the dorsum. Facial line about 45° : profile slightly incurved along the line of
the interparietal and frontal bones. Snout protractile, lips thick, lower jaw
longest. Eyes rather large and near the facial outline- Nostrils double,
covered with a valve half way between the anterior edge of the orbit and the
upper lip.

Lateral line nearly concurrent with the back. Scale? large, deciduous.
Smaller on the summit of the head, and on the opercle, at the base of the tail,
anal and ventral fins, and on the space bounded anteriorly by the ventrals and
pectorals.
'Extreme length 6.5 in., width 3 in., weight 2 oz.

Color. Back varying from ash color to dark brown ; irregular black patches,
approximating somewhat to bands, across the sides. Belly lemon yellow,
becoming lighter and blending with the ash color up the sides. Sides, in some,
punctated with black. Dark and yellow patches on the fins. D. 28, P. 18, V. 6,
A. 25 to 28, C 20.

Var. B. Facial line not so angular as the other, head deeper, and less dorsal
curvature.

The anatomy of these fishes is similar to that of the viviparous species
which I have already described, except that the uterus, instead of being bipar-
tite, is ovoid, having but a single umbilical cord, which returns its venous blood
into the portal system. Intestinal canal 6 in. long, enlarged at each extremity.
The specimens of this fish were presented to me for description by my friend, Dr.
J. B. Trask, who obtained them through the kindness of Mr. Morris, from the
lagoons of the Sacramento river, and from the river itself, where they are found
as high up as the fishermen have yet been. They are the first specimens of
the fresh water vivipara that have come to hand.

Hyperprosopon argenteum, Gibbons.

Body compressed, oval. Jaws with a double row of teeth, inner row imper-
fectly developed. Cheeks and opercle scaly, membranous round the edges.

106

slightly curved rays, first short, half as long as second, second and third half as
long as its succeeding one. Articulated rays 28. Dorsal groove obsolete along
soft rays, the spinous rays projecting above it. Pectoral cuneate, with one very
short subspinous ray. Ventrals with one spinous and five articulated rays ;
connected with the abdomen by a membrane. A space extending from the base
of the ventrals to the vaginal orifice 1 in. wide, free of scales. First three
rays of anal fin spinous^; two rows of fine scales along tbe base of the anterior
third ; the posterior tw% thirds situated in a groove. Nostrils double, anterior
ones closed with a valve.

Back regularly arched, with a slight incurvation in some along the frontal
bone. Curve of the belly greater than that of the back. Latter line com-
mencing at the upper angle of the opercle and nearly concurrent with the
back. Eyes very large, irides white, with a brown crescent above. Lips thin.
Jaws slightly protractile. Upper lip on a line with the superior edge of the
pupil, and with sides nearly vertical when the mouth is open. Head ash color
and dark brown. Back light brown with metallic tints, silver white below
the lateral line ; 22 — 24 silver white longitudinal stripes. Scales above the
lateral line, around the tail and anal fin smaller than the others. Outer edge

9 spinous, first short, second, third and fourth double the length of its pre-
ceding one ; V. 6, first spinous ; A. 15 or 16, first three short and spinous ;
C. 20 ; P. 20 or 24, first short and spinous.

Cymatogaster minimus, Gibbons.

Back more curved than the preceding ; back brown and with metallic tints,
sides punctate with black, with lemon color patches along the middle. A dif-
fused dark brown or black spot on the dorsal about the end of the spinous rays ;
membranes of the dorsal, the tail and anal punctated black, ventrals yellow at
base, tipped with black; a diffused black patch under the pectorals.

D. 23 or 24, V. 6, A. IS to 20, P. 20 to 24, C. 20. About the same size as the
preceding species.

Var. All the characteristics of the type, but with larger scales and of a
lighter color. Extreme length 6 in., width 3.25.

Of the genus Cymatogaster 1 have already described two species.

Say, Journ. Acad. Nat. Sc. 3, 197.

Nebraska and Texas. The largest of our species, and very distinct by the
large subquadrate cinereous spot just behind the base of the elytra: the outer
margin of the spot is prolonged along the side of the elytra, and extends on the
humerus : the inner anterior angle is prolonged towards the suture, while the
inner posterior an^le is prolonged backwards; excluding the prolongation, this
spot is about one half longer than wide, and the inner prolongation is small
compared with the outer portion, which is one third the length of the elytra : in
the next species the inner prolongation is large, so that the mark appears like
an irregular subbasal fascia, and the spot itself is not longer than wide.

Erichson (Ins. Deutschl. 430, note) gives as synonyms D. caninus Germ., and
D. tesselatns Herbtt. This view appears to me entirely unfounded. The true
marmoratus Say, seems not to be known to the German entomologists. By in-
advertence Erichson also quotes the Trans. Am. Phil. Society, for the original
description of Say.

2. D. Mannerheimii, oblongus, niger, pubescens, capite thoraceque fulvo-
variegatis, hoc punctis cinereis tribus ornato, elytris cinereo variegatis, fascia

albo ornatis, antennis obscure ferrugineis. Long. -31 — '37.

Dermestes marmoratus\ Mannerheim, Bull. Mosc, 1843, 258.

San Diego and San Francisco, California. The small size given by Count
Mannerheim, enables his specimens to be referred to this species : its characters
are sufficiently pointed out above. The spot or fascia extends one fourth the
length of the elytra.

3. D. f a s c i a t u s, oblongus, niger, pubescens, capite thoraceque fulvo varie-

New Mexico, Mr. Fendler : also allied to the two preceding, but the fascia
of the elytra is not connected with the base, is not dilated externally, and hardly
even touches the scutel ; the latter as in D. marmoratus and Mannerheimii is
cinereous.

4. D. nu bil u s, oblongus, niger, pubescens, capite thoraceque cinereo fu I voque

in Canada (Kirby). The general direction of the markings of the elytra is
transverse, sometimes they are so numerous that the elytra appear dull cinereous,
with a few transverse black lines.

5. D. murinus, oblongus niger, pubescens, capite thoraceque cinereo-ful-

Linn. Faun. Suec. (synon. vid. Erichson, Ins. Deutschl. 429).

Middle and Southern States and Nebraska ; probably imported. This species
differs from the last by the color of the antennae : the markings of the elytra are
less disposed to become confluent.

6. D. s o b r in u s, oblongus, niger, subaequaliter fusco-pubescens, (sparsius
in elytris) ; subtus albidus, abdomine maculis nigris quadruplici serie ornato,
femoribus albo-annulatis, antennis obscure ferrugineis. Lonjj. -32.

One specimen, Texas, Mr. Haldeman. This has entirely the form of D.
nubilus, but the uniform pubescence, and the four abdominal series of spots will
enable it to be readily recognized : the last joint of the abdomen is white, with
two lateral and two fainter internal black spots at the base, corresponding to
the spots on the other segments.

7. D. talpinus, oblongus, niger, pubescens, capite thoraceque cinereo va-
riegatis, pilis fulvis intermixtis, scutello fulvo pubescente, elytris lineolis
angustis transversis cinereis variegatis; subtus albidus, abdominis lateribus seg-
mentoque ultimo nigris, hoc basi albo bimaculato, antennis piceis apice dilutiori-
bus, femoribus albo annulatis. Long. *24 — '32.

Mannerheim, Bull. Mosc. 1853, 257.

California and Oregon ; abundant. The lines of the elytra are very narrow,
and occasionally are varied with fulvous hairs : the color appears from the nar-
rowness of the markings much darker than in our Eastern species.

8. D. r a 1 1 u s, oblongus magis elongatus, griseo-pubescens, (maculis denudatis
variegatis) thorace minus subtiliter punctato, subtus albidus, abdomine griseo
nebuloso, antennis nigris. Long. '20'.

One specimen, California, Mr. Child. This species is a little narrower than
the preceding, and from the appearance of the hair of the upper surface looks as
if well preserved specimens would be uniformly pubescent, as in the densely
pubescent varieties of D. murinus. The specimen being a female, I am not
certain that it belongs to this division, but have placed it near those to which it
seems most closely allied. The hairs of the thorax appear slightly intermixed
with fulvous, and the punctures are more distinct than usual. The pectus is
white as usual, but the abdomen is of a dirty clouded white color, becoming
white only at the middle of the base.

9. D. m u c o r e u s, oblongus, magis elongatus, nigro-piceus, pubescens, tho-
race lateribus et apice, elytrisque versus basin densius pubescentibus, subtus
candidus, segmentis abdominis gutta utrinque nigra notatis, (pedibus anten-
nisque piceo-rufis). Long. -23.

One mile from New York. This specimen is evidently immature, but the
white undersurface, marked only with the black lateral spots will enable it to
be recognized : the last segment of the abdomen is white, having only the lateral
spot each side at the base. The femora are not annulated. The appearance is
that of a small D. vulpinus, but the sexual characters are those of the present
group.

10. D. p u 1 c h e r, oblongus, rufus, subtilius cinereo pubescens, elytris nigris
hurneris oblique runs. Long. *25.

Philadelphia, Mr. Newman, in a dead oak tree. A moderately robust species,
uniformly but not densely pubescent, both above and beneath, and very re-
markable by its color. The elytra in some lights show some very faint traces
of striaj behind the middle. Five specimens were found.

New York, Nebraska, Texas, California. The variety is quite abundant in
the two localities last mentioned. Erichson describes the last segment of the
abdomen as having a broad black vitta ; as, however, the tip is pubescent, and
the lateral spots also large, it seems more natural to describe it as having two
white spots at the base extending beyond the middle. By comparison with
other species, it will be seen that this is the most common form of marking, and
that in the present species, the spots are merely exaggerated beyond their usual
size. The antennae and feet are piceous, the bases of the thighs, especially of
the posterior pair are covered with white pubescence.

One female, Santa Fe, New Mexico, Mr. Fendler. Less convex than the
preceding, and easily known by the brown pubescence of the upper surface.
The thorax is twice as wide as long, finely p-inctulate, not very convex, broadly
bisinuate at base, with the posterior angles slightly produced.

Say's description is as follows: 'Body reddish brown, with very numerous

short, ferrujinous, somewhat rigid, sericeous hairs : head blackish with an ob-
scure rufous frontal spot; antennae pale rufous, terminal joint dark brown;
mouth rufous ; thorax nearly as dark as the head ; elytra paler than the thorax ;

One male, New Mexico, Mr. Fendler. Differs from all the others known to
me by the coarser and longer dark greyish hair of the upper surface ; the last
joint of the antennae is as long as the others united, and is slightly sinuate inter-
nally towards the apex. The thorax is more than twice as wide as long, not
very convex, shining and finely but not densely punctulate ; the base is broadly
bisinuate and impressed, the posterior angles are rounded.

Megatoma ornata Say, Journ. Acad. Nat. Sc. 5, 185.

One specimen from Texas, Mr. Lindheimer and others from New York. This
species has precisely the form of the next, but is readily distinguished by the fine
dense punctures of the thorax, and the finer punctures of the elytra. The pubes-
cence of the thorax forms two yellow transverse lines, one near the tip, the
other at the middle, and some basal white spots : that of the elytra, forms three
narrow dentated lines and a basal, irregular spot; the anterior and medial lines
are somewhat connected towards the suture. The club of the antennae is elon-
gated, composed of five points not very loosely articulated in the female, and is
broad and serrate in the male.

Ziegler, Proc. Acad. Nat. Sc. 2,269.

One female, Georgia. This species is very closely allied to T. ornatum, but
the less dense punctures of the thorox will enable it to be separated. The
specimen described by Mr. Zeigler was evidently only recently transformed,
and therefore had not yet attained its full color. The club of the antennae is as

The antennae and thighs are black; the tibiae and tarsi brownish; the under
surface is covered with white scales, portions of the pectus, and a lateral row of

Abundant in spring, on flowers, especially on those of the Peony; probably
imported from Europe, but now found even in California ; the larva is very
njurious to zoological collections. The antennae are entirely black, the club
narrower than in the preceding species, oval, with the three joints about equal
in size. The white scales of the under surface of the body are mixed towards
the sides and tip of the abdomen with yellow, the first segment of the abdomen
is entirely covered with scales.

One specimen, New York, Mr. Calverley. The club of the antennae is broad,
round and compressed ; the first joint of it is very small, and the second only
half as large as the last joint. The spots of the elytra seem inclined to form
three fasciae, and there is, besides, one at the middle of the base of each elytron.
The form of the body is that of A. thoracicus, and as in that species the first
joint of the abdomen has a denuded black line each side behind the coxa and the
white scales are mixed with yellow towards the sides of the abdomen.

Castanea pumila. This species seems to be similar to A. museorum ; but I
cannot discover any sexual differences in a large number of specimens examined.
The antennae are sometimes dark-colored towards the extremity; the feet also
vary in color, the thighs being usually darker than the tibiae and tarsi : the elytra
are generally uniform testaceous brown, sometimes the margin and suture are
dark fuscous.

A curious little insect, covered with long erect hair, and presenting the ap-
pearance of the European Trinodes ; the antennae are precisely as in that genus ;
the prosternum, however, is truncate behind, and the anterior coxae are moderately
separated; the mesosternum is short, transverse and rounded anteriorly, while
in Trinodes it is cleft as in Anthrenus, Trogoderma, &c. The legs are slender,
the tibiae not dilated; the joints of the tarsi diminish in length from the first to
the fourth, the fifth is about equal to the first. In all other characters it agree
with Trinodes.

yellowish brown.

114 [June,

The original type of this species, said to have come from Georgia, was
kindly given me by Dr. Melsheimer. When it came into my possession, it was
covered with an incrustation like mud, which induced Dr. Schaum and myself
to consider it formerly as allied to Georyssus. By softening and cleaning the
specimen, it was prepared for examination, and I then found all its characters
to be of the present genus. The br sties were mostly gone, but a few re-
mained about the head and thorax, indicating them to be short and yellowish
white. A few small white scales remain on the under surface, but all vestige
of such a covering on the upper surface is removed. I perceive no characters
by which it can be separated from th> European S. paleata Er. (Ins.
Deutschl. 470,) although a comparison of specimens is necessary before it can
be placed as synonymous with that epecies.

Lake Superior. Differs from the following species by its smaller size, and
by the elytra being broader and more obtuse posteriorly, whereby the body as-
sumes an ovate form, not seen in the allied species. The markings are very
similar to the next species, but the posterior transverse black spot extending
from near the margin to the middle of each elytron is not seen in B. ameri-
canus. The small silvery spots forming the transverse sinuated figure are
frequently not apparent. I have changed the name given by Mr. Kirby, as
it is preoccupied by a European species.

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.

Tail feathers all black ; the entire outer webs and tips of the two exterior white,
the third narrowly margined and tipped with the same. Bill short. Tail con-
siderably rounded.

Total length 4 inches and 4-10ths, wing 1 9-10ths, tail 2, bill from front 4-lOths,
tarsus 6-10ths.

Differs from C. ccerulea in shorter bill and more rounded tail, the outer
feathers of which are not white but nearly black. The black frontlet is also
wanting. Differs from C. atricapilla in absence of black on the top of the head,
this being replaced by a dark stripe on the side. Mr. Lawrence describes the C
atricapilla as having the outer web only of the lateral tail feathers white, but
Bonaparte states the whole feathers to be white.

Bill-Williams' Fork, Feb. 1854.

Psaltria plumbea, Baird.

Upper parts bluish grey, including the crown ; beneath dirty white or brown-
ish white ; cheeks, throat, and forehead tinged with light brown ; outer margins
of all the quills and tail feathers like the back, but brighter (excepting on the
two outer primaries.) Bill and feet black.

Length 4£ inches, wing 2 i-10ths, tail 2 4'j-lOths, tarsus 7-10ths.

Compared with specimens from California of P. minima, this species differs
in having the top of the head uniform with the back ; the whole dimensions
larger, and the bill smaller and more delicate.

Hab. Little Colorado, N. M.

Cyanocitta macrolopha, Baird.

General appearance that of C. stelleri. Tail rounded. Head with a very long
pointed crest, the longest feathers about twice the length of the bill*. Head and
upper part of the neck all round, clear sooty black ; crest glossy, greenish black.
Whole back and scapulars and thighs brownish ash, with a slight' gloss of green.
Rump, upper tailcoverts, sides and whole under parts light cobalt blue. Tail
and exposed surfaces of the secondaries and tertiaries ultramarine blue ; outer
webs of primaries more like the rump. Tail feathers, tertiaries and outer webs
of secondaries distinctly barred with black. The short elongated pointed exte-
rior feathers of the forehead streaked with opaque greenish white, turning to
greenish on those more posterior ; over the eye on the eyelids, a row of silky
white feathers.

Length 12i inches, wing 6, tail 5|.

This bird is figured in Fauna Boreali Americana, Birds pi. 54.

1854.] 119

Differs from C. stelleri in longer and narrower crest, the deeper black of the
head ; the feathers on the side of the forehead streaked with white, not green;
the white feathers over the eye ; more grey on the feathers of the chin at base ;
narrower bill, &c.

100 miles west of Albuquerque, N. M.

Carpodacus cassinii, Baird.

Bill very stout and much elongated, straight or even concave for four-fifths its
length, then gently curved. Wings lengthened ; 2d and 3d quills nearly equal
and longest. 1st intermediate between the 3d and 4th. Tail moderately broad;
quite deeply emarginate ; inner feathers nearly the one fourth of an inch shorter
than the outer.

Male. Whole upper part of the head from the bill to the neck of a rich deep
crimson ; sides of the head below the eyes, chin, throat and upper part of the
breast pale purplish. Feathers on the lower part of the hind neck, back, and
scapulars gray, and with a dark brown central streak, and glossed all over with
purplish. Breast, abdomen, belly, and crissum uniform wThite, anteriorly tinged
with purplish gray, laterally streaked with brown ; under tail coverts white,
similarly streaked. Lower part of the back and rump faintly purplish. Quills
and rectrices brown ; all margined with dull purplish. Secondary and tertiary
quills and primary coverts more broadly margined. Lesser coverts strongly
glossed with purple.

The female is larger than that of C. obscurus ; wings longer ; belly immaculate,
streaked only on the sides.

Male. Total length 6i inches, wing 3 7-12ths, tail 2 10-I2ths, tarsus 7 |-12ths,
bill on ridge 6 £-12ths.

This very strongly marked species may be distinguished by the very long and
nearly straight bill wrhich is larger than in any other N. American species. The
crimson of the head extends to the cervix as in C. purpureus ; the back is con-
spicuously streaked ; the lower parts white and streaked only laterally ; the
reverse being the case in C '. familiaris . It resembles C. purpureus most, but is
larger, bill, wings and tail longer, with less purple on the breast, &c.

Camp 104, Pueblo Creek, N. M., and 75 miles west of Albuquerque.

This species is named in honor of Mr. John Cassin, of the Academy of Natu-
ral Sciences of Philadelphia.

Zonotrichia fallax, Baird.

This species bears a very close resemblance to Z. melodia, of which it is the
western representative. Compared with Z. melodia the bill is considerably
smaller and the tail longer. The plumage above is more ashy, the streaks on
the back not so distinct, the spots are more crowded about the breast, but fewer
on the sides ; their color more uniformly chesnut brown.

Length 6i inches, wing 2 8-l0ths, tail 3.

Pueblo creek, New Mexico.

Pipilo mesoleucus, Baird.

Bill considerably curved and inflexed at edges. Tarsi short, outer claw reaching
a little beyond the base of the middle claw. Above nearly uniform dull olive
brown, except a patch of dark chestnut on the top of the head; chin, throat and
upper part of the breast pale reddish white, streaked on the border of the area
with brown ; and below this there is a central large spot, formed by the adja-
cent brown inner vanes of several feathers. This spot is below the collar of
smaller ones just described. Middle of the breast and abdomen white. Lower
part of the belly, crissum, and under tail coverts light ferruginous. Sides like
the back with a slight tinge of rufous. Wings and tail like the back, the latter
with rusty tips.

Total length 81 inches, wing 3 ll-12ths, tail 4 7-12ths, tarsus 5-12ths.

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 nearljr 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.

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. Snout pro-
tractile ; cheeks and opercula covered with scales, the latter with a thin mem-
brane round the edges. Teeth conical, few, in a single row in each jaw.
Branchiostegal rays five. Dorsal commences posterior to the pectorals ; lateral
line nearly concurrent. Spinous rays of the dorsal fold into a groove sufficiently
deep to conceal them. A narrow, naked space two scales below the base of
the middle and posterior portion of the dorsal ; the lengLh of this space not con-
stant in the same species, but present in all the viviparous genera.

H. Agassizi, Gibbons. — Curve of the dorsum and belly correspond ; a slight
indentation at the base of the head; jaws equal; dorsal with 9 to 11 spinous
rays, first one about a quarter inch long ; 2d, double or treble the length of the
1st; the others gradually lengthening to the 6th, which is .75 inches; the others
about of equal length ; soft portion at its commencement about double the height
of the spinous, regularly increasing to its termination, £ inch high. 1st ray of
the pectorals and ventrals spinous ; that of the former very short ; first 3 rays
of anal short and spinous. A space, free of scales, extending from the base of
the ventrals on each side to the base of the anal ; the scales lining the edge of
this space are folded ; in the unimpregnated state, the opposite edges of this
space meet. Ryes of medium size, irides varying in color with white, brown
and yellow; superior anterior edge of the pupil flattened; nostrils double;
cranium covered with mucous ducts as far down as the nostrils ; a diffused patch
of ducts between the nostrils and the angles of the mouth.

Head transparent gray, dark brown or black ; back ash color, dark brown and
olive, with metallic tints; sides copper brown, lightening into beautiful iridescent
and flesh color or rose tints as they approach the ventrals. From 24 to 26 longi-
tudinal stripes of silver white or flesh tints below, and varying from this to yellow
or greenish-yellow as they ascend. Above the lateral line these stripes are nearly
concurrent with the dorsum, but below they are nearly straight and parallel.
Fins and tail irregularly marked with brown, black, olive or yellow. An ultra-
marine blue round the preopercle, under the orbit, and about the angle of the
mouth.

Scales on the breast and along the base of the fins smaller than elsewhere.
Extreme length, 15 inches; width, 6 inches ; weight, 1 to 3 lbs.

preceding species : back with a sharp ridge, anterior to the dorsal; curve of the
belly slight till it comes to the base of the anal, at which point it takes an an-
gular turn of about 00°, so as to throw the anal rays in a horizontal direction.

Var. A. Facial line not so angular as the other, head deeper, less dorsal cur-
vature, and no black bands.

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. Trask, who obtained them through the kindness of Mr.
Morris, from the fresh water lagoons of the Sacramento river, and from the
river, where they are found as high up as the fishermen have yet been.

Dr. Leidy made the following remarks.

My friend, Mr. Hanson, has called my attention to a review of the work
entitled, " A Flora and Fauna within Living Animals,'5 in the Gardener's
Chronicle, London, April 8, 18-'54, edited by Prof. Lindley. The language in
several passages of this review, would imply that the entophyta, described in
the "Flora and Fauna," had not been discovered by its author. This, though
no doubt unintentional on the part of the editor, is ypt so apt to mislead the
judgment of the readers of the Gardener's Chroniclp, in estimating the value of
the work, that I have considered it, in justice to myself, worthy of notice.

Prof. Lindley remarks in reference to the work, " It may be true, that it dops
not contain much, which may not be found in Robin's second edition of his ad-
mirable work on animals;" and further on, says, " We would point out more
especially the plates, which represent the curious parasites which infest the
intestines of different species of Julus, for though the principal of them are not
overlooked by Robin, etc."

Thus it is made to appear, as if Robin had been the discoverer of most of
the entophytes, described in the " Floia and Fauna," when on referring to pages
358, 395 and 403 of Robin's Histoire Naturelle des Vegetaux Parasites, it will
be found that all the vegetable parasites of the former work are duly accredited
to its author.

The " Flora and Fauna " was presented for publication to the Smithsonian
Institute in December, 1851, and appeared in printed form in April, 1853, the
same year in which the second edition of Robin's work was issued from the
press. The descriptions in the latter of those entophyta discovered by me, were
taken from communications, published in the Proceedings of this Society in 1849.

1 take this occasion to make a few remarks on a question in the same review,
which Prof. Lindley proposes, in reference to the nature of the entophytes above
indicated, whether they are to be considered as fungi or algae. Prof. Lindley
observes, " for our own part, we have little doubt that they are all true fungals,
as also are such productions as Saprolegnia, etc." In presenting an opinion
with so little doubt, Prof. Lindley appears not to be " an coura>it>> with a work
entitled, "The Vegetable Kingdom. 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.

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. Pectorals broad
and large, its longest rays extending posteriorly as far as the fifth ray of second

Genus ASPICOTTUS. Girard.

Head covered with bony plates. Opercular apparatus armed with strong spines.
.Mouth moderately cleft; jaw equal. Teeth on the maxillaries and front of
vomer; none on the palatines. Gill openings separated by an isthmus ; bran-
chiostegal rays six in number. Dorsals distinct; first, rather small and lower
than the second. Caudal rounded posteriorly. Pectorals broad and large.
Insertion of ventrals under the base of pectorals. A series of bony scutellae
running along the sides of back from head to tail. Skin otherwise smooth.

Obs. — To this genus must be referred Cottus bubalis of Euphrasen, from the
Baltic and Norwegian seas.

3. Aspicottus bison, G. — Greatest length seven inches and a half. 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.

tinuous for the whole length of the body.

4. Leptocottus armatus, G. — Greatest length of specimens observed, about
ten inches. Head forming more than the third of that length, caudal tin included.
Surface of head and snout spineless. The only spines observable are situated on
the preopercle ; a very stout one terminated by three conical processi directed
upwards and forwards, and a small, blunt one beneath directed downwards. The
origin of the first dorsal is situated in a line with the posterior cutaneous flap of
the opercle and upper edge of insertion of the pectorals ; its base is about half
that of the second dorsal. The caudal is subtruncated. The anal is much lower
than the second dorsal and not quite as long. The insertion of ventrals is be-
neath the pectorals and nearer to the snout than to the vent. The tips of pecto-
rals extend to a line corresponding to the anterior ray of second dorsal, which is
in advance of the vent.

ance. A few small spines on the opercular apparatus. Mouth deeply cleft.
Jaws equal. Teeth on the maxillaries, front of vomer, and on the palatines.
Gill openings continuous; branchiostegal rays, six in number. Dorsals distinct

tinct and continuous the whole length of the body.

5. Scorp.exichthys marjioratls, G. — A large species, of which several speci-
mens were procured. The head forms the third of the length, the caudal fin ex-
cluded. A rather small and blunt spine is situated above and inwardly of the ante-
rior nostril. The snout is rounded and gradually sloping anteriorly. The posterior
extremity of the upper maxillary extends a little beyond the posterior rim of
the eye. The preopercle is armed with two small spines only, and occasionally
with the rudiments of a third. The other pieces of the opercular apparatus are
spineless. A cutaneous, branching flap, similar to those of Scorpceiia, is observ-
able above the posterior rim of the orbit. The first dorsal begins immediately
behind the occiput, with a base almost as long as the head, being composed of
eleven rays, the last sending its membrane to the anterior ray of the second dor-
sal, which is one-fifth of its length longer than the anterior one. The anal is
but little shorter than the anterior dorsal. The insertion of ventrals is a little
nearer to the anal than to the tip of lower jaw. and are composed of five soft
rays and a spine. The pectorals, composed of sixteen rays, are large and
broadly developed, extending posteriorly beyond the tip of ventrals, reaching a

BETEROLEPIM: s* Catafkracti*

We propose forming under the above name a new ichthyic group of the well
known genus Chirus, and a new one described below under the name of Ophiodon*

The natural characters by wrhich this group or family is distinguished are : a
body elongated, compressed and tapering; covered with rather small scales. Two
long dorsal fins occupying almost the whole of the dorsal region. Verrtrals
situated under the pectorals. Canine teeth upon the jaws, canine or velvet-like
ones on the vomer and palatines. Preopercle and opercle either smooth or
provided with spines. The posterior suborbital sends a narrow arcade to the
limb of the preopercle as in the Cottcrids properly so called ; that bony arcade
being concealed under the flesh, skin and scales constituting the cheeks.

CHIRUS, Steller.

This Genus we shall, for the present, characterise as follows :• a superciliary,
membranous arborescent flap. Mouth of medium size; canine teeth on both jaws j
velvet teeth on the front of vomer and palatines* Preopercle and opercle
without any spines. Cheek, opercular apparatus, and top of head, covered with
small scales. Gill openings continuous and not separated under the throat.
Branchiostegal rays six in number* Scales finely serrated posteriorly* Several
lateral lines*

7. Chirus p ictus, G* — About twelve inches in total length, in which the head
is contained four and a half times. Eyes elliptical, longest diameter contained
five times in the length of side of the head. Dorsals contiguous at their base
only* Origin of anterior dorsal opposite the posterior flap of opercle. Anal as-
long as the second dorsal ; membrane uniting the rays deeply indentated. Cau-
dal posteriorly sub-convex.

8* Chikus guttatus, G .—Closely allied to the preceding, from which it is1
distinguished by a larger eye and broader scales, the posterior margin of which
is much more serrated, so as to be much rougher to the touch. The origin of
first dorsal is situated in advance of the posterior flap of opercle* The super-
ciliary flap is much less developed. The caudal is subconcave posteriorly.

The second Genus of this group, for which the name of

OPHIODON, Girard,

is proposed, has a more elongated head than the preceding one. Its mouth is
deeply cleft ; canine teeth exist on both jaws, rather more developed than in Chi-
r?is. The vomer is possessed with similar teeth as well as the palatines, where
they form a very long series. Posterior convexity of preopercle provided with
small spines. Minute scattered scales on the head, cheeks and opercular appa-
ratus. Branchial apertures continuous; branchiostegal rays six in number,
scales very small.

9. Ophiodonelongatus, G — Largest specimen observed, twelve inches long,
the head forming about one fourth of that length ; the greatest depth, measured
at the origin of the trunk enters seven times in the total length. The thickness
is one third less than the depth. The body is gradually diminishing backwards,
both in height and depth. The upper surface of the skull is slightly concave.
Eyes, subcircular and quite large, their horizontal diameter being comprised five
times in the length of side of the head. The posterior extremity of the upper
maxillary extends beyond the posterior rim of the orbit. The anterior suborbi-
tal overlaps the upper maxillary. Six or more small spines may be observed
upon the posterior curve of preopercle. The upper angle of qpercle terminates
in an acute processus. The subopercle is very long and stretches considerably
beyond the opercle. The origin of the first dorsal is situated in advance of the
spiny limb of the preopercle, at a distance of four tenths of an inch from I he
occiput; it is contiguous to the second dorsal, which terminates at an inch and
three tenths from the base of caudal (not from its rudimentary rays). The
anal is nearly the same length with the second dorsal. The tips of pectoral ex-
tend beyond the tip of ventrals.

The scales are small, elongated, smooth and entire upon their anterior margin.
They extend somewh-it over the base of the fins.

The color is very imperfectly preserved ; upon a dull yellowish ground may
be seen, on the upper part of the body, dark or blackish brown spots irregularly
scattered; the head appears uniform blackish brown. Beneath dull whitish
yellow; scales silvery. Fins greenish yellow; ventrals and analunicolor ; rest
exhibiting greyish spots.

der appearance; body tapering gradually towards the base of caudal. Greatest
length an inch and three quarters ; head forming the third of it— caudal fin ex-
cluded— and covered with long plates so finely granulated as to appear smooth.
Body perfectly smooth from head to tail. Two small dorsal spines; a third
very minute one at the origin of the soft dorsal fin. Ventral spines quite small,
exhibiting but few and very minute spiculae upon its upper margin. Caudal pos-

|ATHERINID^.

Genus ATHERINOPSIS, Girard.

This genus is intended to include such species of Atherina, in which the palate
is unprovided with teeth, having besides a mugiloid fashioned mouth ; the inter-
maxillaries constitute its upper arcade, exclusive of the maxillaries, which are
situated behind.

12. Atherinopsis californiensis, G. — Specimens measuring seven inches
and a half in total length were observed ; the head forming exactly the sixth
part of it. The body is very compressed, slender and very graceful. The cau-
dal fin is deeply forked ; the base of anal is equal to the length of head ; the
base of second dorsal is scarcely half as long as that of anal. Insertion of ven-
trals equidistant between the tip of snout and posterior extremity of base of
anal fin. Tip of pectorals not reaching the insertion of ventrals. Eye large
and subcircular, nearer to the tip of snout of one of its diameter than to the pos-
terior edge of opercle. The mouth is quite small. The head above is slightly
convex.

The scales are very large, constituting but thirteen distinct longitudinal rows
upon the line of greatest depth of body. They are anteriorly rounded and pos-
teriorly truncated, the margin of which, in the latter region, is ornamented by
a series of tooth shaped serratures, more conspicuous upon large and somewhat
dried specimens.

Greyish brown above, dull buff beneath the silvery band. Fins unicolor,
dull yellowish or greyish. When the scales are removed the upper part of the
body is reddish brown; the lower part lighter with a silvery reflection.

GOBID^E.

13. Gobius gracilis, G. — About three inches and a quarter in length; the
body is slender, compressed and tapering. The head, which partakes of the
slender aspect of the body, forms about the fourth part of the whole length. The
mouth is very larsje ; its angles corresponding to a vertical line which would
pass near the middle of the pupil. The eye is large and elliptical, situated near
the summit of the head and its longitudinal diameter comprised a little more
ti an four times in the length of side of head. The intevocular space above
measures a fifteenth of an inch. The dorsal and anal are rather long. The
caudal is posteriorly rounded or else convex upon its margin. Insertion of ven-
trals in advance of anterior margin of first dorsal and behind those of pectorals.

EMBIOTOCOID^.

14. Embiotoca lineata, G. — Body elongated, regularly arched on both the
dorsal and ventral lines from head to posterior extremities of base of dorsal and
anal fins. In specimens eight inches and a half in total length, the head is
found to constitute a little less than the fourth of that dimension : the greatest
depth, taken upon the middle of abdomen, does not enter three times in the
length. The mouth is small ; the posterior extremity of upper maxillary not

1854.] 135

extending to the anterior rim of orbit. Eye circular : its diameter entering
four times in length of side of head. Origin of first dorsal opposite the middle
of base of pectorals, its base being nearly equal to that of anal and a little
shorter than that of second dorsal. Caudal forked.

The scales are subquadran^ular in shape, a little longer than high, provided
anteriorly with from five to seven grooves.

Deep purplish brown above the lateral line, lighter beneath; sides of abdo-
men yellowish. Longitudinal light stripes between the rows of scales, more
conspicuous below than above the lateral line. Dorsals, anal, caudal and ven-
trals purplish, base of anal exhibiting a whitish stripe. Pectorals whitish or
yellowish.

From San Francisco, Cal.

15. Amphistichus similis, G. — Among the specimens collected, there is one
— a female — a little over four inches and a half in length, which we propose to
describe as a very closely allied species to A. argenteus. There are two promi-
nent characters which will enable us to distinguish between both species : in A.
argenteus the posterior extremity of upper maxillary extends beyond to a
vertical line which would pass through the middle of the pupil, whilst in A.
similis it scarcely reaches the anterior rim of the same organ. Again, in the
former, the second and third spiny rays of the anal are much longer than in the
latter. The number of rays of fins is nearly the same; the anal has three and
the pectorals two more soft rays in A. argenteus than in A. similis. There are
also eleven spiny rays to the anterior dorsal of A. argenteus.

D X. 24. A III. 25. C 2. 1. 6. 6. 1. 3. V I. 5. P 1. 24.

The head is contained three times in the length, the caudal fin excluded. The
eye large and circular, enters less than four times in the length of side of head
by its diameter. The greatest depth is to the greatest length, as one to three.
The body is very much compressed. The insertion of ventrals is in a line with
the third spine of anterior dorsal, which is also the line of greatest depth.

The coloration is not sufficiently preserved for comparative description.

16. Amphistichus heermanni, G. — A specimen of this species, a little over
eight inches and a half in length, in affording one character proper to Holconotus
has left us for some time in doubt as to its generic affinities. We speak of the
structure of the dorsals, the anterior of which is composed of spiny rays higher
than the soft ones of the second. Indeed, there is a slight depression in the line
limiting these fins, corresponding to their point of junction ; but finding that such
was also the case in Holconotus, that character could no longer be of any
generic value. Seeing, however, that there were two rows of teeth on the lower
jaw as well as on the upper, and that the lips, rather thin, were not free upon
the symphysis of the lower jaw, we decided on placing it in the genus Amphis-
tichus where it really belongs. The shape and size of the mouth are altogether
similar to that observed in A. argenteus and A. similis.

The body is very much compressed, of a short appearance, the nape promi-
nently arched, the head contained about four tim^s in the total length and the
greatest depth twice, the caudal fin excluded- Eye contained about four times
in the length of side of head. The posterior extremity of upper maxillary hardly
reaching the vertical of the anterior rim of pupil.

The number of rays of the fins is the same as in A. argenteus, with an excep-
tion in the first dorsal, which has ten spines, instead of eleven, as in A. similis.

17. Gir.A conocepiiala, B. and G. — There was but one specimen of this
species collected, about seven inches and a half in length. General shape sub-
fusiform, compressed ; back slightly convex from nape to posterior margin of

136 [August,

dorsal fin. The head is subcorneal and contained exactly four times in the
length, the caudal fin excluded. The mouth is comparatively large, although
the posterior extremity of the intermaxillary does not quite extend to the anterior
rim of the eye : the snout being prolonged, and the cleft of the mouth nearly
horizontal. The eye is subcircular and its diameter contained five times and a
half in the length of side of head. The anterior margin of the dorsal is nearer
the end of snout than to the tip of central rays of caudal. The caudal itself is
forked and participates of the slender appearance of the body. The origin of
anal is situated behind the base of the dorsal, but at the same time in advance
of the tip of the rays of the latter. The insertion of ventrals is situated in advance
of the anterior margin of dorsal ; their tip reaching the anus.

Genus POGOXICHTHYS, Girard.

Shape of mouth as in Gila; angle of mouth provided with a small filiform
barbel. Body fusiform and compressed. Caudal forked. Insertion of ventrals
behind anterior margin of dorsal. Scales large and uniform. Lateral line below
middle of flanks.

This genus represents in the western waters of North America that of Gobio,
to which it is intimately related.

18. Pogonichthys injEquilobus, B. and G — General form very regular, sub-
fusiform and compressed. Total length of specimen described, about ten inches,
of which the head forms a little less than the sixth part. The eye is subcircular ;
its diameter comprised about five times in the length of side of head. The mouth
is of medium size; its cleft does not extend to a vertical line which would pass
in advance of the orbit. A barbel, about an eighth of an inch, may be observed
at the angle of the mouth. The origin of dorsal fin is equidistant between the
extremity of the snout and the first rudimentary rays of the caudal. The caudal
is long and deeply-forked ; its upper lobe projecting beyond the lower, although
the structure of that fin is perfectly homorcercal. The anal is inserted behind
the dorsal. The insertion of the ventrals is situated a little behind the origin of
the dorsal, and consequently a little nearer the rudimentary rays of caudal than
to extremity of snout. The pectorals are moderate.

The scales are large ; fifty-six of these may be counted in the lateral line,
which, upon the abdomen, approximates more to the ventral than the dorsal
outline. The upper legions of head and body are greyish brown ; the sides and
abdompn yellowish. The fins partake of the color of the region of the body to
which they belong.

From the San Joaquin river, Cal.

19. Pogoni 'hthys symmetricus, B. and G. — The specimens before us being
in a rather poor state of preservation, a description of the species can hardly be
drawn with accuracy. The size of the largest is about four inches and a half in
total length ; the profile of body is subfusiform, very compressed, and gracefully
elongated. The head constitutes the fifth of the length. The eye is large and
its diameter contained less than four times in the length of side of head. The
lobes of the caudal fin are symmetrical. The anterior margin of dorsal is equidis-
tant between the end of snout and the extremity of central rays of the caudal.
The lateral line forms a gentle curve, convex downwards, upon the middle of
the abdomen, and nearer the insertion of ventrals than base of dorsal. The in-
sertion of ventrals is situated in advance of the anterior margin of dorsal, a char-
acter which will at once enable us to distinguish this species from P.
inasquilobus .

Genus LAVINIA, Girard.

Mouth shaped as in Gila and Pogonickthys, but proportionally smaller
than either and unprovided with barbel. Body covered with large scales
as in Pogonichthys. The genus Lavinia, therefore, is intermediate between the
two above mentioned.

20. Lavinia exilicatjda, B. and G.— Body compressed, swollen upon its middle
and tapering towards both extremities. Tail more particularly attenuated.
Greatest depth, in advance of the dorsal, contained about four times in the length,
which is eleven inches, and in which the head enters five times and a half. The
mouth is very small ; its am>le being far from reaching the anterior margin of
the orbit. The eye is circular and rather below the medium size ; its diameter
being contained nearly six times in the length of side of head. Isthmus very
small; branchiostesal rays three on either side. Anterior margin of dorsal
equidistant between the extremity of snout and tip of central rays of caudal,
which latter fin is deeply forked. Base of anal longer than that of dorsal but
considerably lower, particularly upon its posterior third. Insertion of ventrals
in advance of the anterior margin of dorsal. Pectorals rather small.

21. Lavinia crassicauda, B. and G. — The body in this species is less deep in
the middle and less attenuated behind than in L. exilicavda. The peduncle of the
tail is largely developed and contrasts greatly with that of the latter mentioned
species. The head and mouth are proportionally larger ; the former being con-
tained four times and a half in the total length ; and the cleft of the second,
although not reaching the anterior ed^e of the orbit, extends, nevertheless, farther
backwards than in L. exilicauda. The greatest depth is about equal to the length
of head. The eye is subcircular, and its diameter contained about six times in
the length of side of head. The caudal is less emarginated posteriorly, and
the insertion of ventrals situated almost under the anterior margin of the dorsal.

The scales are much larger than in L. fx/licauda,and the course of the lateral
line similar, being composed of about fifty-five scales. The general coloration
is the same.

Specimens were procured at San Francisco, in the Rio San Joaquin, and several
tributaries of that basin.

22. Lavinia conformis, B. and G. — Only one specimen of this species was
obtained; its total length being about four inches. It is related to L. crassicav-
da, having like it a much more compact tail than L. exilicauda. The general
appearance of the fish is suggestive of L. crassicauda; the body is deeper and
proportionally less elongated ; the eye much smaller and the scales larger. Ano-
ther distinctive mark between the two species consists in the position of the vent-
rals, the insertion of which in L. conformis, is situated in advance of the an-
terior margin of dorsal, whilst it is placed slightly behind it in L. crassicauda.

23. Leucosomus occidentalis, B. and G. — Numerous immature specimens of
this species were collected, together with one about five inches in length. The
body is very much compressed, deepest upon the middle of its length and taper-
ing towards both extremities. The greatest depth is contained four times in the

138 [August,

total length. The snout is subcorneal, head rather small, forming about the
fifth of the total length, and slightly depressed above the eyes. The anterior
margin of dorsal is nearer the base of caudal than to extremity of snout. The
caudal is forked. Both the anal and dorsal are anteriorly elevated. Insertion
of ventrals situated in advance of anterior margin of dorsal. Pectorals and vent-
rals of medium development.

CLUPEIDiE.

24. Clupea mirabilis, G. — Specimens before us are from eight to nine inches
in total length, the head forming about the fifth of that dimension. The greatest
depth is equal to length of head. The lower jaw is longer than the upper, the
posterior extremity reaches to a vertical which would pass through the middle
of the pupil. The eye is subcircular and large; its diameter being contained a
little less than four times in the length of side of head. The anterior rays of
dorsal are almost as high as the fin is long. The insertion of ventrals is situated
in advance of middle of dorsal.

This species is closely allied to the common herring (Clupea harengus) by its
general appearance; the absence of teeth upon the palatine, the conspicuousness
of the vomerine teeth (which are most so of all), and the presence of but two
rows of them upon the tongue, will enable any one to draw the distinction be-
tween the two species.

From San Francisco, Cal.

25. Meletta C/Erulea, G. — The body is slender, gracefully elongated, ten
inches in total length, of which the head constitutes the fourth part, not includ-
ing the caudal fin. The depth measured in advance of dorsal, stands in relation
to the total length as one to six. The body tapers away backwards from the
insertion of ventrals and dorsal ; in advance of these fins to the occiput its depth
is sensibly the same, when the head again gradually slopes, above and below,
towards the snout. The posterior extremity of the maxillary reaches a vertical
line which would intersect the middle of the eye The posterior edge of oper-
cular apparatus forms a uniform and rather flattened curve. The inferior branch
of preopercle exhibits small radiating striae ; strias more conspicuous are observed
upon the inferior and inner half of opercle. The anterior margin of dorsal is
nearer the snout than to the base of caudal. The ventrals are inserted opposite
the posterior half of dorsal. Caudal deeply forked ; anal long and low. Pectorals
of medium development and acute upon their extremity.

26. Engraulis mordax, G. — The general physiognomy of this species is some-
what susgestive of EngravHs encrasirholus, the common anchovy of Europe,
from which, however, it may be distinguished chiefly by the position of the
ventrals, the insertion of which is exactly opposite the anterior margin of the
dorsal. The body is slender and compressed, sharp upon the ventral line. The
greatest depth is comprised nearly seven times in the total length and almost
twice in the length of the head. The eye is large and subcircular ; its diameter
being contained four times in the length of side of head. The anterior margin
of dorsal is nearer the base of caudal than to the extremity of snout.

By Charles Girard.

1. Chirus constellatus, G. — This species comes nearest to C. guttatus, of
which it has the general physiognomy and structure of the fins ; but the head
above is less convex, and the scales very differently imbricated. Thus, whilst
in C. constellatus they constitute oblique series which may be traced in any di-
rection, the same is not the case in C. guttatus.

The ground color is greenish grey; the body at large exhibiting indistinct,
cloudy spots, and on the anterior and upper region, groups of black dots varying
in number. Similar dots are scattered over the upper part and sides of head,
and the pectoral fins are literally covered with them, so as to divide equally the
space with the ground color which make these fins appear maculated with
black and yellow.

Genus PORICHTHYS, Girard.

General form and external aspect similar to Batrachus, but more elongated ;
its generic features will consist in the series of pores extending to the whole
length of body from divers regions of the head. There are neither scales on the
body nor membranous appendages on the margin of the jaws. Two short tenta-
cles in advance of the nostrils. The teeth are slender and acute; those on the
vomer most conspicuous. The head is smooth ; the opercle provided with one
spine only.

Ohs* — To this genus belong : 1st. P. porosessimus {Batrachus porosissimus,
Cuv. and Val.) from the coast of Brazil ; and 2d. P.porosus {Batrachus porosus,
Cuv. and Val.) from Valparaiso.

3. Porichthys notatus, G. — Total length about nine inches and a half, the
head forming the fourth of it in excluding the caudal fin. The mouth is broadly
cleft ; the posterior extremity of upper maxillary extending beyond the posterior
rim of the orbit. The teeth upon the symphysis of the lower jaw are more
slender and smaller than on the sides cf that bone. The smallest teeth are those
of the irttermaxillaries extending almost to the whole length of these bones.
The palatine teeth are a little larger posteriorly than anteriorly. The most con-
spicuous ones are observed on the vomer. Two minute and inconspicuous spines
constitute the anterior dorsal fin. The second dorsal is somewhat higher than
the anal, and the tips of the posterior rays of both of these fins reach the
base of the caudal, there being but a narrow space left separating these fins
from each other. The caudal is posteriorly rounded. The pectorals are spear-
shaped ; the central rays being the longest.

numerous specimens brought home by several parties, and now before us, the
largest measures less than six inches in total length. The body is slender,

142 [August,

elongated and compressed, rather graceful in appearance. The head is contain-
ed four times and a half in the total length. The snout is pointed, the upper
jaw overlapping considerably the lower one. The mouth is proportionally large,
the posterior extremity of the upper maxillary extending to a vertical line which
would fall in advance of the eye. The eye itself is above the medium size, sub-
circular in form, and contained about four times and a half in the length of the
side of head. There exists a space between each dorsal, more considerable be-
tween the second and third, than between the first and second. The anals
are likewise separated by a space nearly equal to that which is observed between
the second and third dorsals. The ventrals are exiguous, their second ray being
prolonged into a filament. The pectorals are small.

Observations upon a collection of Fishes made on the Pacific coast of the United
States, by Lieut* W. P. Trowbridge, U. S. A., for the Museum of the Smith-
sonian Institution.

By Charles Girard.

It is praiseworthy for officers of the government, whether military or civil,
when detailed upon special duties, to devote their moments of leisure in serving
the cause of science. Lieut. Trowbridge, while engaged under instructions from
the IT. S. Coast Survey, in making tidal observations for the use of that office,
availed himself of such opportunities at his command to secure the fishes enume-
rated below, and we leave it to Naturalists to decide whether his labors were
at all rewarded.

There are three main points whence specimens were obtained. 1st, Presidio,
on the Bay of San Francisco, where Lieut. Trowbridge himself is stationed ;
2d, Monterey, on the Bay of the same name, where the same gentleman made
several excursions; and, 3d, San Diego, where observations are conducted by
Corporal A. Cassidy, U. S. A.

PERCID^.

1. Labra.x nebulifer, G. — The head which is" contained about three times
in the length, the caudal fin excepted, presents a subcorneal appearance, from the
fact of its bein.; rounded upon its upper region, and gradually sloping towards
the snout. The anterior part of the body, from the origin of the dorsal to the
occiput is continuous with the profile of the head, the middle region slightly
convex. The body gradually tapers backwards; the greatest depth taken
between the insertion of ventrals and origin of first dorsal, is a little less than
the fourth of the entire length, including the caudal fin ; the greatest thickness
measures in the same region as the depth, is a little more than the half of the
latter. The body, therefore, is compressed, as usual in this genus, and the

1854.] 143

general outline subfusiform. The eye is subeircular, and its horizontal diameter
contained about six times in the length of side of head. The posterior extremity
of the upper maxillary extends to a vertical line intersecting the pupil. The
lower jaw is the longest. The third dorsal spine is much the longest in the first
dorsal fin, and higher than any of the rays constituting the second dorsal. The
caudal is subemarginated posteriorly. The insertion of pectorals is placed im-
mediately in advance of the origin of anterior dorsal ; the insertion of ventrals
is situated immediately behind the base of pectorals.

The scales are of medium size. The lateral line follows the curve of the back
and middle of the peduncle of tail.

Ground color reddish brown above, yellowish beneath, upper part of body
provided with large cloud-like blackish blotches. A dark vitta extends oblique-
ly downwards and backwards from the lower rim of orbit to the throat, across
the cheeks and branchiostegal apparatus. The fins are purplish blue, very
intense on the ventrals, base of second dorsal, and space between the third
and fourth spine of first dorsal. The snout is covered with small roundish
spots.

From Monterey, Cal.

2. Labrax clathratus, G. — The profile of upper part of head is more de-
pressed, and the head more acute than in L. nebidlfer. The lower jaw is more
protruding, giving to the snout a pointed, instead of a rounded appearance, which
it has in the preceding species. The fourth dorsal spine is the longest and equal
in height to the highest rays of the second dorsal. The diameter of the eye is

TRACHINID.E s. Percid-e.

Genus HETEROSTICHUS, Girard.

First dorsal fin very long, the first five anterior rays of which constitute an
apparently distinct fin. Anal very Ions, provided anteriorly with but few spines.
Dorsal and anal extending to near the caudal. Body very compressed and
flattened posteriory. Caudal slender. Ventrals situated in advance of pec-
torals. Lower jaw longest ; mouth moderate. Teeth small and conical. Scales
very small. Lateral line arched above the pectorals. Six branchial rays.
Opercular apparatus without either spines or denticulations.

3. Heterostichus rostratus, G. — The head is rather small and conical,
contiguous to a body anteriorly deep, tapering posteriorly, and very much flat-
tened throughout. The nose is very much depressed and concave. The
greatest depth measured above the pectoials, is contained five times in the entire
length; the least depth is about the fourth or fifth of the greatest. The head
forms a little less than the fourth of the length. The mouth is moderate, lower
jaw much the longest ; and the posterior extremity of upper maxillary reaches a
vertical line, which would pass in advance of the pupil. The teeth are conical,
slender and exiguous. The eye is subelliptical, and its horizontal diameter con-
tained seven times and a half in the length of side of head. The dorsal fin
originates at a very short distance from the occiput. The five first rays consti-
tuting an apparently distinct fin, subtriangular in shape, and much higher than
the portion which follows, and which upon its anterior half, is higher than the
posterior half. The soft dorsal is short, but high and in perfect continuity with
the spiny one ; the tips of its posterior rays not reaching quite as far back as

144 [August,

those of the anal, which approximate to the base of caudal. The caudal is
slender and forked. The anal is very long and higher than the corresponding
portion of dorsal ; it is highest posteriorly and lowest upon the middle. The
base of the pectorals falls under the space between the third and fourth dorsal
spines. The ventrals are inserted much in advance of the base of pectorals,
immediately under the throat ; they are qaite small and slender. The pectorals
themselves are of but medium development.

The scales are very small, extending over the upper part of opercular appara-
tus to the cheeks ; also to the rays of the fins to about half their height or length.
The lateral line, from the upper angle of opercle runs almost straight till about
under the twelfth spine of dorsal, then obliquely downwards until near the middle
of flanks, thence straight to the base of caudal.

Ground color above yellowish brown with irregularly transverse blotches, or
else interrupted, and then constituting longitudinal bands of a deeper hue. Head
above deep brown; upper part of opercular apparatus exhibiting an elongated
triangularly acute blotch, starting from the rim of the orbit. Sides and inferior
surface of head yellowish. Belly dull yellow. Fins yellowish, blotched, except
the pectorals, which are barred transversely, and the ventrals which are unicolor.

Greatest length of specimen described about eleven inches.

SPHYR^ENID^ s. Percims.

4. Sphyr^ena argentea, G. — A specimen of this species which lies before us,
is thirty-five inches in total length, of which the head forms a little less than the
fourth part. The body is stoutish, thickest upon its middle and somewhat com-
pressed, the depth being about one-third more than the thickness. The mouth
is moderate ; the posterior extremity of upper maxillary leaves a distance of
three fourths of an inch between it and the vertical of the anterior rim of the
orbit. Teeth on the intermaxillary, minute ; on the lower jaw, moderate ; on
the palate, conspicuous and strong.

The eye is subelliptical, its anterior rim a little nearer to the tip of lower
jaw than to the posterior flap of opercular apparatus. The scales on the cheeks
are smaller than upon the opercular pieces ; there are none to be seen in advance
of the eye. The posterior extremity of anterior dorsal is nearly equidistant
between the tip of lower jaw and the base of central rays of caudal. The latter
is deeply forked. The extremity of pectorals is very far from reaching the
anterior margin of first dorsal. The upper margin of both, the second dorsal and
anal, is concave.

The scales are of rather medium size on the flanks, smaller on the back. The
lateral line is straight.

The ground color of the upper region of head and body above the lateral line,
is bluish black; whitish on the sides and yellowish on the abdomen. The scales
have an argentine reflection which extends to the sides of the head and lower
jaw. The lateral line is black. The membrane of the dorsal, caudal, anal and
pectorals is yellowish, and their rays greyish; the ventrals are uniform
yellowish.

COTTIDiE s. Cataphracti.

5. Cottopsis parvus, G. — May readily be distinguished from Cuttopsi* gulosus
by a more compact and more fusiform body, a smaller head and consequently a
much smaller mouth. The pectorals and ventrals are less developed, and the
outline of the first dorsal is more convex. The caudal is posteriorly subtruncated.
The insertion of ventrals is situated immediately behind the base of pectorals,
and a little in advance of the origin of the first dorsal ; and when brought back-
wards, their tip does not reach the anus. The tip of pectorals extends to a ver-
tical line which would pass in advance of the origin of anal. The anal is much
ovver than the second dorsal.

The head constitutes the fourth of the total length; it is quite depressed, and
slopes gradually towards the snout; its width is one fourth greater than its
depth. The eyes, of medium size, are placed near the summit of the head ; their
form is subcircular, and their horizontal diameter contained four times and a
half in the length of side of head. The posterior extremity of upper maxillary
reaches a vertical which would pass in advance of the pupil.

Minute prickles are scattered all over the skin, more developed above the
lateral line than beneath it. The lateral line, itself very conspicuous, follows
the curve of the back uninterrupted to the base of caudal.

Ground color yellowish brown above and on the sides; dull yellowish beneath.
Sides and back with darker somewhat confluent blotches, or else groups of
crowded dots resembling blotches. The pectorals, dorsals and caudal are barred ;
the anal and ventrals unicolor. First dorsal with a blackish blotch upon its upper
and posterior portion. Base of caudal with a black bar, upper surface of head
covered with dark roundish small spots.

8. Scorp.enichthys lateralis, G. — We know but a few small individuals of
this species, the largest of which is less than four inches long. The body is
compressed and tapering; the head being contained about three times in the
length, excluding the caudal fin. The occipital region is flattened; the inter-
ocular space, convex, and the rostral distance, declive. The mouth is large :
the posterior extremity of upper maxillary extends to a vertical line, which
would intersect the posterior margin of the pupil. The eye is large, subcircular,
and placed near the summit of the head; its horizontal diameter is contained
four times in the length of the side of head. The interocular space is quite
narrow. The opercular apparatus exhibits but a double spine of moderate de-
velopment, situated upon the upper half of the limb of preopercle, with its point
directed obliquely upwards. The caudal fin is posteriorly subrounded. The
insertion of ventrals is situated under the middle of the base of pectorals. The
origin of the dorsal is in advance of base of the same tins. The first dorsal is
rather low, and not contiguous to the second, which is considerably higher.

Oa the upper portion of dorsal region, alongside the dorsals, may be seen an
elongated area covered with small pectinated scales or plates, disposed upon
oblique or transverse rows. The skin is otherwise smooth, and the lateral line
conspicuous, making a slight inflexion downwards upon the middle of the
abdomen.

Upper region of head and body deep chestnut brown, variegated on the sides
with shining yellowish areola? and dots. Inferior surface of head, belly an I
tail uniform yellow. Fins spotted or barred.

SCORP.ENID.E s. Catapiiracti.

9. Scorp.-exa guttata, G The head has a pretty rough appearance : in the

first place, the orbits seem as if emerging from the upper part of the skull, the
middle line of which exhibits an obtuse groove. Three spines are observed
along the upper edge of the orbit, behind which three more may be seen on
either side of the occipital region and nape. Several supratympanic spines, but
small ; two diverging ones, upon the body of opercle, and four upon the limb ol
preopercle, the uppermost of which being much the stoutest and longest. Next
we see four other spines irradiating downwards from the suborbitals, and finally
the nasal bone terminates into a sharp and acute point directed upwards and
slightly backwards. Intermingled with these numerous spines there are but two

y 13

146 [August,

pairs of small membranous and arborescent flaps, — we were going to say, —
adorning the head, but in reality contributing to render it still more repulsive to
an eye unitiated to scientific pursuits: the first pair is situated above the poste-
rior part of the orbit, whilst the second occupies the inner upper edge of anterior
nostril. The body is about eleven inches in total length, the head forming the
third of it. The eye is large and elliptical: its horizontal diameter being com-
prised nearly five times in the length of side of head. The posterior extremity
of upper maxillary reaches a vertical line which would intersect the posterior
rim of orbit. The second dorsal has nearly the same height as the first. The
caudal is sabrounded posteriorly. The tips of posterior lays of anal are even
with those of the second dorsal. The insertion of ventrals is under the base of
pectorals ; they are elongated. The pectorals are broad and very much de-
veloped ; their posterior extremity extending considerably beyond that of ven-
trals.

The scales of body are of medium size, and very small upon the occipital
region and the head. The opercular apparatus is naked ; scales being observed
upon the posterior flap of opercle only. Ground color deep reddish brown above ;

Clouded patches of blackish, here and there, with numerous small black spots,
more defined on the head than on the body, and much larger on the fins. Belly

From Presidio, Cal.

11. Sebastes rosaceus, G. — The general form of this species might at first
be suggestive of S. norvegicus, were the central rays of the first dorsal not so
much higher than in the latter species, giving to that fin a decided convexity.
The fish is rather stout than elongated, though much compressed, the depth of
body being about equal to the third of entire length, which is about fourteen
inches, and nearly equal to the length of head. The profile from the anterior
margin of first dorsal to the end of snout is rather depressed, whilst it tapers
quite rapidly from the second dorsal backwards, the peduncle of the tail being
rather detached from the general shape. The upper part of head exhibits but
two small horizontal spines, whilst the preopercle has five of them, rather stout
and conspicuous. The upper part of opercle has two spines, the uppermost of
which is the largest. The eyes are large and subcircular, reaching the upper
profile of head, in the length of which their horizontal diameter is comprised four
times, once in advance the anterior rim of orbit, and twice behind its posterior
rim. The mouth is broad, but the posterior extremity of upper maxillary does
not extend beyond a vertical line which would intersect the centre of the pupil.
The second dorsal is scarce higher than the first. The posterior margin of caudal
is slightly concave. The second spine of the anal is strong and robust ; the
tips of the posterior soft rays of that fin extend somewhat farther back than
those of the second dorsal, but do not reach the base of the rays of the caudal.
The insertion of ventrals is situated immediately behind the base of pectorals.
The pectorals are very long, their tips extending beyond that of ventrals, and
reaching a vertical line which would fall between the two dorsals.

The scales of the body are of medium size ; those upon the head, cheeks, oper-
cular pieces and throat are quite small. The course of the lateral line is parallel
to the outline of the back.

The color is of a uniform reddish or crimson tint, lighter beneath. There
exists, on the upper part of opercle, in the region occupied by the spines above
alluded to, a large, elongated spot of a much deeper hue.

From San Diego, Cal.

12. Sebastes fasciatus, G. — The species which we propose here to charac-
terize, has more of the general aspect of a Scorpceita, than of the genus to which
it belongs. The body, anteriorly, is very stout and deep, the head more rounded,

1854.] 147

with its upper profile more inclined from the occiput to the snout than in the pre-
ceding species. The total length of the fish is about eleven inches, of which
the head forms more than the third. The »reatest depth is equal to the length
of head. The upper surface of the latter exhibits conspicuous spiny ridges, very
acute posteriorly. Five triangular spines occupy the limb of preopercle and two
the upper part of opercle. The posterior extremity of upper maxillary reaches
a vertical line which would pass behind the pupil. The outline of anterior dorsal
is convex and about the same height as the second. The caudal, posteriorly, is
subrouuded. The tips of posterior soft rays of anal are even with the tips of
posterior soft rays of second dorsal, and both fins approximate the base of caudal.
The ventrals are long and their tip reaches the vent. The pectorals are broad
and extend a little farther back than the ventrals, the insertion of which is
situated upon a line behind their base.

The scales are rather above the medium size ; those on the bead and opercular
bones being comparatively more developed than in the preceding species. The
lateral line is parallel to the outline of the back.

The ground color is greenish sulphur yellow ; purplish black patches over the
head, sides of body, and fins, in the midst of which patches appear crowded
whitish spots. An area of ground color may be traced from the third and fourth
dorsal spines obliquely downwards and backwards, towards the base of the caudal;
in an oblique direction from the dorsal fin to the lateral line; then along the
course of lateral line to the base of caudal fin. The throat is deep sulphur yellow;
the inferior surface of the head and belly is spread all over with a more dull tint.

18. Glyphisodox RUBicuxDrs, G. — The head has a very short appearance ns
well as the body itself. The largest specimen measures nine inches and a half

n total length, of which the head forms a little less than the fourth. The an-

erior upper part of body is very convex^and the profile of the head very declive

with two depression?, one above, the other below the ocular region. The mouth

•s small and the lips very fleshy. The eye is situated high up, small and cir-

' ular, and contained five times in the length of the side of head by its diameter.

The greatest depth, measured above the ventrals, is a little less than twice the

length of head. The dorsal fin begins a little behind the base of pectorals ; its

pinous portion is low and its upper margin almost straight ; the soft part rises

'ntoa subtriangular shape. The peduncle of tail is well defined, free above and

below j the dorsal, however, coming nearer to the base of caudal than the anal

■ ;oes. The caudal is very large, deeply emarginated. but the lobes are uniformly

rounded and broad. The soft portion of anal has the same conico-trianeular shape

as the soft dorsal. The ventrals are elongated and inserted behind the base

of pectorals. The latter are quite broad, rounded upon their external margin ;

their posterior extremity falling short of that of the ventrals.

is large, obliquely directed upwards, and the posterior extremity of the upper
maxillary extends to a vertical line which would pass behind the orbit. The
origin of dorsal is situated opposite the base of pectorals. A stylet-shaped bone
in advance of the anterior margin of anal, which is much nearer the extremity
of caudal than to the base of pectorals. The pectorals are short and rounded

The eye is subcircular, of medium size, and its horizontal diameter contained
five times in the length of the side of head. The mouth is likewise obliquely
directed upwards ; but the posterior extremity of the upper maxillary extends
only to a vertical line which would intersect the pupil. The origin of the dorsal
is situated immediately behind the base of the pectorals: its anterior third is
lower than the rest. The origin of the anal, which is much lower than the two
posterior thirds of the dorsal, is much nearer the base of the pectorals than to
the extremity of th* caudal. The latter is very small, posteriorly rounded, and
contiguous to both the dorsal and anal. The pectorals are short and rounded.

The scales are small, but proportionally larger than in the preceding species;
and the lateral line, which is very conspicuous, may be traced from the upper
margin of the opercle to near the caudal ; from the opercle it ascends obliquely
for a certain distance, and then follows the outline of the back, keeping much
nearer the base of dorsal fin than the middle of the flanks.

The anterior portion of body and head is of a uniform deep violet ; the posterior
portion exhibits a somewhat brownish ground, over which is spread a violaceous
tint ; the fins are all deep violet. A deep purple crescent-shaped vitta extends
from either eye to the occiput. Two oblique vitta? on the sides of head, start-
ing, one from the anterior, the other from the posterior half of orbit to the bran-
chiostegal apparatus. The interocular space is likewise marked with a transverse
narrow band slightly convex backwards.

26. Jults modestus, G. — Body slender, elongated, and much compressed,
tapering posteriorly from the origin of anal. The greatest depth, measured upon
the middle of the abdomen, enters five or six times in the total length. The
head is subcorneal, and constitutes about the fifth of the entire length. The eye
is large, subcircular, and its horizontal diameter is contained four times and a
half in the length of side of head. The dorsal commences above the base of the
pectorals, being quite low for about half its length, and terminating at about
three quarters of an inch from the base of the caudal. The origin of the anal is
opposite the eleventh ray of the dorsal, and extends a little further back; the
depth of that fin is equal to the height of the portion of the dorsal opposite to it.
The eaudal is posteriorly subtruncated. The insertion of ventrals is opposite
the posterior extremity of base of pectorals, and their tips do not extend as far
back as those of the latter fins.

A large specimen of this species, collected at San Diego, Cal., contained five
young ones, the total length of the largest beinu nearly three inches, and its
depth equal to the third of its length. Their bodies are light reddish orange,
with the peculiar longitudinal light strip?s very conspicuous. The two anterior
thirds of dorsals, the anterior third of anal, and the base of ventrals exhibiting a
deeper reddish orange ; the posterior portion of dorsal and of anal fins are rather
yellowish. An elongated jet black spot exists near the base of the anterior
portion of the soft dorsal ; the tip of ventrals is black ; the margin of the anterior
dorsal fin also black.

The caudal is long and truncated ; the extremities of both the dorsal and anal
fins extend beyond the base of caudal as appears to be the case in the young of
Rhacochilns tozotes.

From Presidio and San Diego, Cal.

30. Embiotoca cassidyi, G. — There is another species of Embiotoca, the young
of which exhibit the same structure ol the fins as observed in those of E. lineata,

152 [August,

and Rhacochilus toxotes. We have before us five immature specimens, the largest
of which measures but two inches and a half, and is consequently smaller than
the largest of E. live at a. They werp collected by A. Cassidy, and sent with
other specimens, without mention being made whether caught freely swimming
in the water, or taken by him fiom the parent hsh. At any rate they are
easily distinguished from those of E. Hit eat a in possessing numerous trans-
verse greyish bands more or less regular from head to tail and from dorsa
to ventral line. The anterior portion of anal, the anterior edge of soft dorsal,
the tip ot spines of first dorsal, and the ventrals are blackish : the remaining
parts of these fins, as well as the caudal and pectorals, are yellowish. The cau-
dal is slightly emarginated posteriorly.

Adult specimens of this species have not yet fallen under our examination.
We have not hesitated in establishing it as distinct from those already described
after the careful study of the young in that family.

31. Holconotcjs niioooTERus, Agass. Amer Jour, of Sc. Second series, xvii.
1854, p. 368.

Sixteen young were taken from ihe parent body; they are from eight-tenths of
an inch to an inch long. A small vitelline sac is still to be observed at the ab-
dominal region. The general form is slender and elongated. The head is deeper
than the body and rounded ; the snout much less prominent than in the adult;
its general outline resembling more that of an adult Amphisti chits. The vertical
fins are much more developed than in the parent ; the caudal is rounded off, the
central rays being the longest. The soft dorsal and anal are likewise higher
and extend posteriorly to the base of the caudal if not slightly beyond it, the dor-
sal at least.

Coloration uniform light yellowish ; fins whitish of an extreme transparency
owinu undoubtedly to their having but shortly escaped from the egg.

Specimens were obtained at Presidio and San Diego, Cal.

32. HoLCONorus trowbridgii, G. — This species is about the size of H. rho-
doterus of which it has the general appearance. The body, however, is propor-
tionally less elongated and consequently more deep. The greatest depth, measured
between the origin of the first dorsal and the base of the ventrals, is contained
three times in the total length, whilst the head enters in it four times and three
fourths. The anterior portion of the body is superiorly very convex, and the
upper surface of head sloping rapidly towards a rounded snout terminated by a
very small mouth ; considerably smaller than in H. rhodoterits, whilst the teeth
are much shorter than in the latter species. The eye is large and circular, and
contained but three tim<--s in the length of the side of head ; the distance between
the anterior rim of the orbit and the end ol the snout is less than one diameter of
the eye. A line drawn vertically down from the origin of the lirst dorsal
would pass immediately behind the basp of the pectorals. The base of the
anal is compris<-d six times and a half in the total length of the fish, whilst
in II. rhoduterns the base of the same fin enters in the length of said species but
five times. The base of the ventrals is nearly equidistant between the symphy-
sis of the lower jaw and the posterior extremity of the base of anal ; in II. rhu-
doterus it is nearer to the snout.

The size of the scales is nearly the same in both II. trowbridgii and II. rko-
doterus.

The upper region, from the end of the snout to the base of caudal is reddish
brown, with irregular interspersed clouded purplish spots. The side of head and
abdomen are silvery. The fins are yellowish ; a cloudlike purplish spot at the
anterior portion of anal. The posterior half of ventral is of a deep purple.

its location we are not prepared to give.

33. Holcoxotus megalops, G. — This species, six inches and a half in total
length, is the largest of its species, as far as observations go. The body is very
much compressed and very deep upon its middle region, tapering rapidly from

1854.J 153

the origin of anal backwards. The greatest depth measured under the anterior
dorsal, is contained a little more than thrice and a half in the total length. The
head forms a little less than the fourth of the whole length. The cephalic
region is concave. Mouth rather above the medium size, its cleft being ob-
liquely directed upwards; the teeth are very exiguous ; the posterior extremity
of upper maxillary does not extend beyond the vertical line of the anterior rim
of orbit, owing to the oblique position of mouth. The eye is very large and cir-
cular ; its diameter being contained less than three times in the length of side of
the head. The anal is very Ions and low posteriorly. The caudal is forked.
The origin of ventrals is under the second spine of the anterior dorsal.

Genus PHANERODON, Girard.

Mouth rather small ; jaws very protractile; teeth large and subcorneal. Lips
not very fleshy ; lower one attached to the symphysis of the jaw. Anterior
part of dorsal fin gradually rising from the first to the last spine, which, however,
is a little shorter than the first articulated ray. Anal very low but quite long,
furnished with bifurcated rays.

This genus is allied to Emhiotoca by the presence of one row of teeth only upon
both the upper and lower jaws, and by the lower lip in not being free all around.
The structure of the dorsal reminds us of Amphistlchus, whilst the shape of the
anal is strongly suggestive of Holconotus.

31. Phankrodox furcatus, G. — Body very flat, seven inches in total length,
tapering more or less rapidly backwards from the origin of both the soft dorsal
an, I anal. The greatest depth of body, measured above the insertion of ventrals,
is contained a little less than three times in the total length, in which the head
enters about four times and a half. The cleft of the mouth does not extend to
the anterior rim of the orbit. The eye is large and circular, and its diameter
comprised three times and a half in the length of side of the head. The inser-
tion of ventrals is opposite the fourth dorsal spine. The base of anal is nearly
equal to that of soft dorsal and lower than the latter, its spiny rays are very
small. The caudal is slender and deeply forked.

36. Posohickthys ARGVUErosus, G. — This species is allied to P. ivceqnilohus;
it is, however, distinct from the latter by the structure of the caudal which is
equilobed like that of P. symmetricus* The head is contained five times in the
rotal length, which, in the specimen before us, is about three inches and three
quarters. The eye is large, subelliptical, and its horizontal diameter contained a
little over three times in the length of the side of head. The budy is compress-
ed, regularly fusiform in its outline. The insertion of ventrals is situated some-

body is compressed, the back slightly arched anteriorly to the dorsal fin. Great-
est depth a little less than the" fifth of the length. Eyes subelliptical, their
horizontal diameter contained four times in the length of side of head: once in
advance of the anterior rim of the orbit. Anterior margin of dorsal equidistant
between tip of snout and posterior margin of caudal, which is subconvex. The
origin of anal is opposite the middle of base of dorsal. All the fins are of small
dimensions.

42. Engraulis delicatissimus, G — The fascies of this species is widely dif-
ferent from that of either E. eacrasieholvs or E. mordax : the body being more
compressed, less tapering, and the head much shorter and less acute. The entire
length of the largest specimen before us is about three inches, the head being
comprised in it nearly five times and a half. The greatest depth of body is a
little less than the length of head, the upper surface of which is convex and but
siishtly declive. The eye is large and circular, and its diameter contained
twice and three fourths of a time in the len»th of the side of head. The origin
of dorsal is nearer the end of snout than to the extremity of caudal fin. The latter
is forked. The base of anal is almost twice as long as that of dorsal, and its an-
terior margin situated opposite the middle region of the latter. The ventrals
are small and short ; the pectorals long and slender.

43. Argentina pretiosa, G. — The body is gracefully elongated, compressed?
fusiform in its outline, six inches and one-third in total length, in which the head
enters for a little less than the fifth. The eye is large and circular, and its hori-
zontal diameter is contained a little over four times in the length of side of head.
The posterior extremity of upper maxillary extends to a vertical line which
would pass in advance of the pupil. The origin of dorsal fin is a little nearer
the tip of lower jaw than to the base of caudal fin. The adipose is situated op-
posite the posterior fourth of anal. The caudal is forked. Trie origin of ventrals
is placed a little behind the vertical line of anterior margin of dorsal ; the fins
are well developed. The pectorals are a little more slender and longer than the
ventrals.

PLEURONECTID^..

44. Flkusonectes maculosus, G. — Body elongated, subelliptical ; dorsal and
ventral outline forming most regular curves into which the head immerges ante-
riorly with but a very slight depression above the eyes. The peduncle of the
tail is slightly contracted immediately behind the posterior margin of both the
dorsal and anal fins, which terminate evenly. From this point to the base of
caudal fin, the caudal region assume a dove tail shape. The caudal fin itself is
undulated posteriorly, the external and central rays being slightly longer than
the intermediate ones. The total length of the fish is about seven inches and a
b,alf, in which length the head enters four times and one third. The lower jaw
is the longest. The posterior extremity of upper maxillary reaches a vertical
line which would pass behind the posterior rim of the orbit. The eyes, placed
on the right side, are of medium size, elliptical, and their horizontal diameter is
contained about five times and a half in the length of the side of head. The
origin of dorsal is opposite the anterior rim of the orbit ; that of the anal is in
advance of the base of pectorals, as also the insertion of the ventrals, which are
short and broad.

DISCOBOLI.

48. Lepadogaster reticulatus, G. — Head broad, semielliptical when viewed
from above; upper surface declive towards thesideSj as well as towards anterior
extremity. It forms nearly the third of the entire length, which, in ihe speci-
men described, is about three inches and a half. Its inferior surface is dattened.

156 [August,

The month is broad in ront, but not deeply cleft; its angle extending to the
vertical of the anterior rim of the eye. The latter is small, subelliptical in
shape, and situated near the upper surface of head; its horizontal diameter is
contained about six times in the length of the side of head. The body is an-
teriorly broader than deep; it diminishes gradually in both height and depth
towards the origin of the tail, which is quite compressed and very much reduced,
and terminated by a slender caudal fin. rounded upon its posterior margin. The
origin of the dorsal fin is situated a little in advance of the anus, but does not
unite with the caudal, between which and the posterior extremity of its base, a
space of three tenths of an inch is left; even the tips of its posterior rays do not
reach the base of the caudal. The anal begins a little further back than
the dorsal, is as deep as the latter is high, and extends likewise a little further
behind; the tips of its posterior rays nearly reaching the base of the caudal.
The pectorals are broad but slioit, the ventrals are imbedded in the membranous
disk peculiar to that group of fishes.

iochcerus ; and have, therefore, not included it in ihe list. The specimens

upon which the former genus was characterised, apparently indicate two distinct

species : whereas, all the teeth which have been found of the latter, so far have

indicated but one species.

Notice of a new genus of Cyprinidce.

By S. F. Batrd and Charles Girard.

COCHLOGNATHUS, B. & G.— The jaws are armed with a spoon-shaped plate,
the edge of which is sharp and cutting. Pharingeal teeih disposed upon one single
row. The general appearance of the fish is cyprinoid, and stiongly suggestive
of Pimephales, the head having a rather robust appearance with a blunt snout.
The mouth itself is rather small. There are no barbies or rudimentary barbies
of any kind. The insertion of the ventral fins is situated opposite the anterior
margin of the dorsal. The caudal is emarginate. The scales are very large.
The lateral line is conspicuous, running through the middle of the flanks, slightly
bent dowtiwards upon the abdomen.

Cochlognathus ornatls, B. & G. — Head forming two ninths of the entire
length, and abruptly rounded off on the snout. Mouth proportionately small and
terminal with oblique cleft. Eyes rather above the medium size ; their diameter
being contained four times in the length of the side of head. Body much com-
pressed, covered with large scales disposed in twelve longitudinal rows on the
line of greatest depth. Lateral line inflexed downwards upon the abdomen.
Anterior margin of dorsal nearly equidistant between the snout and rudimentary
rays of the caudal. Anal, situated entirely backwards of the dorsal. Caudal
forked. Insertion of ventrals beneath the anterior margin of dorsal ; tip of pec-
toral not reaching them.

D I. 8. A 6. C 4. 1. 9. 8. 1. 3. V 8. P 12.

The colors, as preserved in alcohol, present a reddish brown ground, and a
dark lateral band or stripe. The dorsal fin exhibits two elongated dark spots,
one anteriorly and basal, the other posteriorly and nearer to its tip. The posterior
half of the caudal has likewise a darker hue than its anterior and basal half,
which is of a dull orange, as is also its extreme margin.

bi color Fabr. (Enc. Syst. Suppl. 50; Syst. El. 1, 152): the description is
"corpus medium; caput ferrugineum antennis oculisque nigris; thorax laevis
glaber ferrugineus macula media nigra; elytra laevia nigra; corpus ferrugineum
pedibus nigris;" this certainly approaches quite closely to the present specie?,
and is very different from any of those to which other authors have applied it.
On account of the slight difference in the antennae, this species is made by Che-
vrolat the type of a separate genus Janessa (vide Dej. Cat).

Kansas River. Body elongate, black shining. Head rufous, finely not densely
punctured. Antennae shorter than the head and thorax, black ; joints 2 — 6 small,
6th hardly wider than the fifth; 7 — 10 broad, transverse, subequal ; 11th round,
almost equal in bulk to the tenth. Thorax, about one fourth longer .than wide,
with the widest part about the middle, very slightly narrowed towards the apex
and base, broadly rounded on the sides, bright rufous, convex, finely not densely
punctured. Elytra with fine, punctu red, not deeply impressed striae, which near
the tip are somewhat obliterated ; interstices distinctly finely punctured. Be-
neath, the head and prothorax are rufous, with the tip of the sternum and coxae
blackish; the other parts are black and very finely punctulate.

One specimen from Georgia. Narrower than the preceding, and entirely
of the same form as L. trifasciata. Body black with a slight brassy tinge ;
head finely not densely punctured: antennae as in L. laeta. Thorax nearly one
half longer than wide, somewhat narrowed anteriorly, broadly rounded on the
sides, dull rufous, finely not densely punctured. Elytra with fine rows of punc-
tures becoming obsolete towards the tip, interstices very obsoletely punctulate.

Western States; occasionally found in Pennsylvania. The elytra are mode-
rately strongly punctato-striate ; the tip is almost smooth. In the female the
thorax is more convex and more rounded on the sides than in the male; the
apical margin of the thorax is frequently blackish. In both sexes the seventh
joint of the antennae is somewhat smaller than the eighth. The under surface is
sparsely punctured.

One specimen, Pennsylvania; Mr. Rathvon. Closely resembles the preceding,
and might readily be taken for a variety of it ; but the antennae are entirely
black, the postpectus and tip of the femora are also black; the limits between
the red and black of the plytra are badly defined; and the punctures of the under
surface are very much finer.

Middle, Southern an*d Western States. Latreille was the first to apply to this
species the description of Fabricius, with which it by no means agrees ; the
other authors above mentioned have merely copied the error from him.

1 should have applied the name given by Newman to this species, were it not
that the size mentioned in his description (long. *6 unc. ; lat. '03 unc.) could
never be attained by it. The relative proportions of the length to the breadth
are., however, impossible in this genus, and in other respects the description
agrees with the species here described.

One specimen, Georgia: resembles in appearance L. puncticollis, but is longer
and narrower. Body rufous ; head finely punctulate. Antennae shorter than the
head and thorax, black, with the second to the sixth joints slender, subequal ;
the 7th is slightly dilated, but not more than half as wide as the 8th, which
again is narrower than the 9th; 9th and 10th equal, slightly transverse ; 11th
rounded. Thorax nearly one half longer than wide, widest about the middle,
broadly rounded on the sides, convex, finely, not densely punctulate, with a dis-
coidal oval black spot reaching from the apex to behind the middle. Elytra not
wider than the thorax, bluish black, with fine rows of punctures becoming obso-
lete at the tip. Beneath rufous, first and second segments of the abdomen
sparsely, coarsely punctured ; fourth and fifth segments black. Legs black, basal
half of the femora rufous.

One specimen found on the sea shore near New York. Body moderately slen-
der, dark rufous tinged with piceous and brassy; head sparsely punctured, punc-
tures finer towards the occiput, which is nearly black. Antennae shorter than
the head and thorax, joints 2 — 6 slender, the third being twice as long as the
second; 7th slightly dilated, 8th still more dilated, but not as wide as the 9th
and 10th, which are somewhat transverse; 11th larger, rounded. Thorax nar-
rowed at the base, more narrowed anteriorly; sides broadly rounded ; disc mo-
derately convex, sparsely, not finely punctured, with a large rounded, ill-defined,
dorsal spot. Elytra brassy black, shining, finely striato-punctate, striae finer
posteriorly, but extending almost to the tip. Under surface entirely rufous with
a piceous tinge, uniformly sparsely punctured. Legs fusco-aeneous, femora, ex-
cept at base, piceous black tinged with brassy; tarsi almost rufous.

Middle, Southern and Western States ; not rare. This species has the antennae
rather stouter than the others of this division, and the fifth and sixth joints are
a little rounded ; the seventh joint is a little smaller than the 8th, which is also
a little smaller than the ninth. By these characters it forms a transition towards
L. trifasciata, of division (B.)

Triplax Payk.

I continue to retain Tritoma united with this genus, as the slight difference in
form will by no means warrant their separation. The differences in the antennae
cannot be considered as of greater value, since in neither of the groups are they
persistent ; finally, the last joint of the maxillary palpi is more transverse in the
genuine Triplax, being about three times wider than long, while in Tritoma the
breadth is only double the length. For convenience in determining the species
they may be arranged in several divisions.

One specimen from Maine, given me by Prof. A. Guyot. Proportionally much
narrower than the next species, which it resembles in coloring, but is distin-
guished by the thorax being less punctured and not narrowed anteriorly ; by the
striae of the elytra being impressed, by the interstices having no distinct punc-
tures, and by the antennae being entirely black.

San Jose, California. Somewhat less convex than the other species, and di -
tinguished from the next, which it resembles in color, by the 8th joint of the
antennae being similar to the seventh. From that, as from all others of division
(A,) it is known by the coarser punctuation and by the very straight sides
of the thorax.

Descriptions of new fossil species from the Cretaceous Formation of Sage Creek,
Nebraska, collected by the North Pacific Railroad Expedition, under Gov.
J. Ji Stevens.

By John Evans, M. D., a*nd B. F. Shumard, M. D.

Avictda triangularis. (Nov. sp.)

Shell small, thin, sub-ovate, length and breadth nearly equal, anterior ex-
tremity pointed, expanding rapidly towards the posterior extremity, which is
rounded below the wing; wing small, triangular; umbones inflated; beaks
pointed and nearly terminal, hinge margin with a well defined furrow running its
entire length ; surface with rounded, concentric slightly elevated ribs, crossed
by indistinct, radiating striae.

Locality. — Cretaceous formation, Sage Creek, Nebraska. The pearly nacre is
finely preserved in all the specimens of this shell that we have seen, forming an
elegant contrast with the dark hue of the matrix.

Avicula lingua for mis. (Nov. sp.)

Syn. — Avicula undet. Owen, Final Rep. Geol. Iowa, Wisconsin and

Minnesota, tab. vii. fig. 10.

Shell very oblique, elongated, linguaeform, moderately convex ; surface smooth;
cardinal line straight, about equal to the greatest width of the shell ; posterior
wing triangular, acute, anterior wing triangular, separated from the body of the
shell, by the continuation of a shallow groove which surrounds its most gibbous
portion ; posterior edge sigmoid, forming an obtuse angle with the cardinal mar-
gin; anterior and basal edges convex ; beaks pointed, projecting a little above
the cardinal border, situated about one-fourth the length of cardinal line from the
anterior extremity. The mould of the shell exhibits a line of small tubercles,
commencing at the point of the beak and extending in a curve to the base of the
posterior muscular impression ; the latter is very large and somewhat reniform.

Length one inch, width at cardinal border 10 lines, length from extremity of
anterior wing to posterior inferior extremity 19 lines.

This species is rather common in the septaria of the cretaceous group at Sage
Creek, Nebraska, but perfect specimens are procured with diificulty.

Solaritim flexistriatum. (Nov. sp.)

Shell small, discoidal, depressed, convex, terminating exteriorly in a sharp
cutting edge ; velutions four or five ; spire very slightly elevated, inner edge of
volutions bounded by a row of tubercles ; surface marked by fine revolving thread-
like striae, which are crossed by fin<± fiexuous striae, giving an exceedingly
neat reticulated appearance to th« shell. Umbilicus large ; mouth sub-quad-
rangular.

Dimensions.— Width, 3i lines ; height, 1J lines.

This pretty shell occurs quite abundantly in septaria of the cretaceous forma-
tion of Sage Creek, Nebraska.

1G4 [August,

Mytilus Galpinianus . (Nov. sp.)

Shell sub-ovate, arcuate, inflated, surface smooth, or marked only by five in-
distinct concentric lines of growth ; umbones prominent, rounded, anterior side
short; beaks nearly terminal, muscular impression small, placed near the an-
terior extremity ; posterior side broad, extremity rounded.

Dimensions. — Length 7.5 lines, width 15 lines, thickness 6 lines. The only
specimen we have of this species is partly denuded of its shell, so that some of
the characters above given may have to be slightly modified, when more perfect
specimens are obtained for examination.

Locality. — Fox Hills, Nebraska. For this species we are indebted to the
politeness of Mr. Galpin, agent of the Amer. Fur Co., in charge of Fort Pierre
Chouteau, and to him it gives us pleasure to dedicate it.

Pholadomya elegantula. (Nov. sp.)

Shell sub-ovate, transverse, inflated; anterior side short, rounded ; posterior
side elongated, gaping; basal margin regularly rounded ; ligament margin arcu-
ate ; umbones prominent ; surface marked with about 45 concentric ribs, which
increase in width from the beak to the fyasal margin, becoming nearly obsolete
posteriorly ; these are crossed by about 25 radiating granular ribs, close together
on the middle portion of the shell, the intervals increasing in width towards the
anterior and posterior borders.

Dimensions. — Length 18 lines, width 22 lines, thickness 1 inch.

Locality. — It occurs in septaria of the cretaceous group at Sage Creek, Ne-
braska, associated with Ammonites Oweni9 Scaphites nodosus and Inoceramus
Sagensis.

Rostellaria Nebrascensis. (Nov. sp.)

Shell elongate, conical ; whorls about eight, convex, body whorl with two well
rounded keels ; lip prolonged transversely, terminating in a sharp point ; all the
volutions ornamented with transverse revolving thread-like striae, which are
crossed longitudinally by prominent flexuous ribs.

It occurs with the preceding species at Sage Creek, Nebraska.

Descriptions of neiv fossil species from the fresh water Tertiary Formation of Ne-
braska, collected by the North Pacific Railroad Expedition, under Gov* J» J»
Stevens.

By John Evans, M. D., and B. F. Shumard, M. D.

The organic remains which form the subject of the present communication
were obtained from Nebraska Territory, in the vicinity of Peno Creek, a small
tributary of Teton or Little Missouri River, about ninety miles from Fort
Pierre Chouteau. They occur in great profusion in thin-bedded, light gray, sili-
ceous limestone, near the summit of the elevated plateaux which border the
Mauvaises Terres. They consist of several species of Lymnea, one Physa, one
Planorbisy the seed vessels of a species of Chara and the carapaces of a minute
Cypris. These genera at once establish the lacustrine character of the deposit
in which they occur. The fossils are beautifully preserved, and project in fine
relief from the weathered surfaces of the limestone. Many of them have been
converted into semi-transparent chalcedony. They are of considerable interest,
from the fact, that the strain in which they are imbedded, repose on the tertiary
marls and clays, which have yielded those magnificent collections of extinct mam-
malian and chelonian remains de^ribed by Prof. J. Leidy, in his recent very
valuable memoirs, published in Dr. Owen's Final Report on the Geology of
Iowa, Wisconsin and Minnesota, the Smithsonian Contributions, and in the Pro-
ceedings of the Academy of Natural Sciences.

Planorbis Nebrascensis. (Nov. sp.)
Shell small, depressed, discoidal, above moderately concave ; volutions about
four, rounded, obtusely carinated ; below rounded, umbilicus small, exhibiting
the volutions to the apex of the spire, suture distinct ; body whorl with an obtuse

1854.] 165

dorsal carina, aperture sub-trigonal, surface marked with delicate, arched striae
of growth.

Width, 2s lines ; height h of a line.

Occurs very abundantly.

Lymnea diaphana. (Nov. sp.)

Shell small, oblong, ovate- conic ; whorls fine, convex, crossed by delicate lines
of growth, spire short, acute at apex ; aperture oval, slightly dilated, rather
larger than half the length of the shell; columella rather delicate and sinuate,
umbilicus minute.

Length, 2j lines ; width, 1J- lines ; length of aperture, \h lines.

Very common.

Lymnea Nebrascensis. (Nov. sp.)

Shell ovate, sub-conic, volutions five, convex, crossed by minute, elevated
lines of growth ; body whorl ventricose, more than twice the length of spire ;
spire short, apex pointed, suture not deeply impressed ; lip produced in front.

Length, 5£ lines ; length of body whorl, 4 lines ; width about 2^ lines.

All the specimens in our possession are very much compressed, and other-
wise mutilated, so that the form and character of the aperture cannot be deter-
mined. It is very similar to the preceding species, from which it is distinguished
by its greater size and its numerous crowded striae.

PHYSA SE.CALINA. (Nov. Sp.)

Shell small, thin, oblong-oval ; volutions four, evenly convex, smooth or with
very fine lines of growth ; aperture ovate, narrow, more than equal to the entire
length of the shell ; spire short, slightly rounded at summit, suture distinct but
slightly impressed.

Length, 2£ lines ; width, \\ lines.

Only two specimens of this little shell have come under our observation, and
these rather imperfect.

Cypris Leidyi. (Nov. sp.)

Carapace minute, reniform, vertical section sub-cordate, width of extremities
nearly equal ; central and anterior portions of surface very convex, the convexi-
ty diminishing towards the posterior end; ventral margin straight or very slightly
concave, about one third shorter than the entire length of the valves; dorsal and
lateral margins convex, encircled by a well defined, narrow groove, which ter-
minates at the ventral margin ; surface covered with exceedingly minute gra-
nulae.

Length, I of a line ; width, \ ; thickness, 2-5th.

A close examination of the slabs of fresh water limestone from the vicinity of
Peno Creek, has resulted in the discovery of this pretty little crustacean. The
substance of the fossil is nearly transparent chalcedony, and the valves in both
specimens remain attached in their normal position.

Named in honor of Prof. Joseph Leidy, whose valuable researches have con-
tributed so largely to our knowledge of the fossil fauna of Nebraska.

umbilicus; siphunculus nearly central ; septa profoundly undulating, showing
on the back a sharp recurved lip.

This is the largest of the genus found in our rocks, being ten inches in dia-
meter. It resembles quite closely N. D aniens, especially in the undulations
of the septa.

Locality, Alabama.

3. N. angulatus. Shell with the septa regularly curved ; emarginated ; me-
dium space wide, flat, obtusely angular; siphunculus large, situated towards
the inner margin of the chamber; aperture very wride.

Readily distinguished from N. Dekayi, which it resembles, by the angles on
the back, and flat median space.

Locality, Mississippi.

2. Ammonites.

1. Ammonites magnificus. Shell compressed, broadly oval ; whorls rapidly
decreasing in size, crossed by coarse nodose ribs ; nodes at each extremity of
the ribs, the outer nodes compressed and arranged on each side of the convex
median space; septa not greatly ramified, dorsal lobe deeply bifurcated.

Bears some resemblance to A. Delawarensis, but is a very distinct species.

Diameter twro feet.

Locality, Pickens county, Alabama.

2. A. earinatus. Shell covered with prominent, closely arranged ribs; ribs
nodose, a little undulating ; nodes in five revolving lines ; nodes on each side of
the median line compressed; median line carinated ; whorls rapidly decreasing
in width ; aperture ovate.

From the preceding species this is distinguished by its more numerous and
closely arranged ribs and numerous nodes.

A cast in calcareous sand, having a portion of the siphunculus beautifully
preserved.

Locality, Columbus, Mississippi. Dr. Spillman.

3. A. binodosus. Shell undulating with lines of growth; nodes in two re-
volving lines, equi-distant from the sides of the whorls, inner line more promi-
nent ; median space narrow, flat ; aperture elliptic.

This very distinct species has a considerable part of the shell remaining com-
pletely silicified.

The narrow, flat median space, the absence of ribs, and two distinct rows of
nodes, separate this from its congeners.

Locality, Vance's Ferry, Alabama.

4. A. lobata. Shell discoid, smooth, thin towards the circumference ; dorsal
lobe finely serrate ; lateral lobes terminating in large bilobed cells.

This fossil, of which I have only a fragment, resembles A. placenta, but is
distinguished from it by the remarkable cells that terminate the lateral lobes.
Locality, Noxubie county, Mississippi. Mr. Richardson.

5. A. ramosissimits. Shell remotely ribbed, slightly nodose; median line com-
pressed ; septa profusely foliated, aperture oval.

The fragments of this fossil in our possession are at once recognised by the
very numerous subdivisions of the lateral lobes of the septa, which cover the
entire surface.

Locality, Sumter county, Alabama.

6. A- angustus. Shell with the whorls compressed crossed by distinct some-
what nodose ribs, each terminating in a robust knob, outside of which is a series
of compressed tubercles; mpdian space narrow and carinated.

Two fragments of this fossil have been found. Portions of the nacreous part
of the shell remain, and show distinctly the deeply foliated margins of the septa.

This is the first notice of the occurrence of the genus Turrulites in the creta-
ceous rocks of the United States.

RUDISTES.

Mr. Lyell was the first to point out the existence of this curious family, in
the cretaceous rocks of the United Slates.

The fragments then known were referred to the genus Hippurites. From that
time to the present I have endeavored, with the assistance of many friends, to
collect the fragments of Rudistes, scattered over the prairie region of Alabama
and Mississippi. The result has been the determination of two genera and
seven species, and, what is remarkable, not a single fragment that could be rer
ferred to the well marked genus Hippurites has as yet been found.

Without figures it is not easy to give characteristics of the species of a
family, the remains of which are so badly preserved. The following, however,
may serve for the present.

Radiolites, Lam.
Sphcerulutes, Delam.

1. R. Ormondii. Shell, lower valve comparatively thin, long, lamellae angular;
lip turned upwards at the outer circumference; ramifications of the mantle
slightly impressed on the lip; cells small; outer surface ornamented with verti-
cal ridges composed of the zigzag edges of the leaves composing the shell ;
inner surface smooth, with a thin plate extending a short distance into the aper-
ture.

Distinguished by the thinness of the shell and ornamented exterior. The
fluting and apparent joints of the outer surface suggest, at first sight, a frag-
ment of a fossil plant.

Inscribed to my friend, Dr. John Ormond, of Tuscaloosa, who discovered this
interesting species.

Locality, Marengo county, Alabama.

2. R. lamellosis. Shell, lower valve thick, conical, large ; lip nearly horizon-
tal, or slightly depressed towards the circumference, with radiating smooth
ridges, more numerous towards the outer circumference; outer edge slightly and

172 [September,

abruptly turned up ; exterior surface with vertical impressed lines correspond-
ing with the ridges on the lip ; cirri or ramifications of the mantle impressed,
dichotomously branching ; cells towards the circumference compressed length-
wise.

The numerous radiating ridges on the lip are characteristic of this species.

Locality , Lowndes county, Alabama.

3. R. Aimesii. Shell, lower valve large, conical, very thick ; lip slightly con-
vex, with narrow, radiating depressions towards the inner circumference, outer
edge slightly plaited, with obsolete concentric undulating lines ; outer surface
striate.

Inscribed to Dr. Aimes, of Montgomery, to whose kindness I owe this fine
fossil.

Locality , Alabama.

4. R. undulata. Shell, lower valve thick; lip bent slightly upwards, with dis-
tant, obtuse radiating ridges, or undulations, and obsolete radiating lines ; cirri
of the mantle well defined.

Locality, Marengo county, Alabama.

Ichthiosarcolites, Desmarest.
Caprinella, d'Orb.

1. /. quadrat) gularis. Shell quadrangular, curved, irregular ; septa somewhat
regular, abruptly bent downwards, and approximating in the channel on the
inner surface of the shell; aperture terminating obliquely and rather abruptly.

Locality, Noxubie county, Mississippi. Mr. Richardson.

2. I. loricatis. Shell, aperture somewhat oval, irregular, obtusely rounded at
the base, giving the cast an imbricated appearance.

Locality, Noxubie county, Mississippi. Mr. Richardson.

3. I. eornutis. Shell, aperture regularly curved, flattened on one side, septa
abruptly bent downwards, and towards the concave side.

Distinguished from the preceding by the more distant and regular septa, and
in the greater regularity of the curvature of the shell.

Locality, Noxubie county, Mississippi. Mr. Richardson.

I have thought proper to restore Desmarest's uncouth name, rather than
violate the rule of priority.

Description of a fossil apparently indicating an extinct species of the

Camel tribe.

By Joseph Leidv, M.D.

Mr. Henry Pratten, of New Harmony, Indiana, has sent for my inspection,
and as a donation to our Academy, an interesting fossil, which be discovered in
the gravel drift of Kansas territory.

The specimen consists of the left intermaxillary bone, containing the fang of
a tooth, and a small portion of the corresponding maxillary bone.

The fang of the tooth is the portion of a transformed incisor or functional
canine, like that in the Camel and Lama. The crown of the tooth was directed
more outwardly than in either of the latter; but it had the same form, being
laterally compressed, obtuse anteriorly and acute posteriorly. At the point of
emergence from its alveolus the crown measured 61 lines antero-posteriorly and
3j lines transversely. Its enamel is thin, and appears to have been smooth.
The fang is laterally compressed, conical, and measures an inch and a half in
length ; and it is strongly curved backward and downward, and is almost paral-
lel with the palatal margin, so that its extremity is only seven lines above the
latter.

The intermaxillary bone is relatively larger and more robust than in the
Camel or Lama, and it is broader and more convex above. Its nasal border is

"ty

1854.] 17o

more obtuse and very much less inclined, so as apparently to indicate a longer
snout in the extinct animal. The anterior or gingeval border is thick and rough
as in other ruminants.

The small portion of the maxillary bone presents the remains of an alveolus,
separated from the tooth of the intermaxillary by an interval, with a curved,
acute margin, an inch and three-quarters long. The great distance of this
alveolus from the tooth in advance, when compared with the condition of things
in the Camel and Lama, arises from the great degree of extension backward and
near the palate of the fang of the first functional canine.

The maxillo-intermaxillary suture, at the side of the fossil, descends, as usual,
parallel with the nasal border of the intermaxillary bone, and, after reaching
the palatal surface is directed in a curved line forward and inward, reaching as
far as the posterior third of the position of the first tooth.

From this description it is evident the fossil indicates a distinct species of the
camel tribe, and as it appears generically distant from the Camel and Lama, the
name of Camelops Kansanus would not be inappropriate for it.

Major Le Conte stated that having visited, during the last spring, an island on
the coast of Georgia, known as Colonel's Island, he had been enabled to pro-
cure from the original locality authentic specimens of Magnolia pyramidata,
mentioned in Bartram Travels, p. 5. On comparison with other specimens, he
is convinced that it is merely a variety ot M. grandiflora ; which varies in the

1854.] 175

form of its leaves from a regular elliptic form to ovate-lanceolate. The di-
mensions of the leaves from Colonel's Island are ll£ inches long and 2J wide.
Those from other localities are,

Of the elliptic form, transverse diameter, 7 inches,
" conjugate, 4 inches.

" ovato-lanceolate 7i long, 3J- wide.
Regular gradations may be found between these various forms. The opinion
expressed by Elliot that M. pyramidata is a variety of M. auriculata is there-
fore erroneous. Major Le Conte also stated, that he had been personally in-
formed by Mr. Bart ram that his M. pyramidata had lanceolate leaves.

As in other species of this genus, the outer antennae have not the double geni-
culation characterising the Oniscidas. The surface of the body is smooth; yet
there are a few exceedingly minute hairs especially along the posterior margin of
the segments of the abdomen. The branches of the caudal stylets in the speci-
men are mutilated.

This genus is between Scyphax and Styloniscus in most of its characters.
Eut the apical process of the maxillipeds is large, as in Oniscus. Moreover,
the bases of the caudal stylets form a border to the last abdominal segment, so
that the apices of the two are brought nearly together.

Both the back and the legs in the specimens are brownish black, fn some
smaller specimens four to five lines long ; the color is light brown, mottled with
yellowish, and the legs are pale yellowish ; the form is a little more slender,
and they may probably be a different species. The last three joints of the outer
antennae are not so nearly equal.

Male. —Head, wings and back, light slate color; the primaries being of a
darker hue, and in their inner vanes barred with white, with which also the ter-
tiaries are tipped. A white line starting from above the eye extends down the
occiput, becoming rufous as it forms a collar on the hind neck. A deep slate
colored moustache descends from the angle of the mouth, one half inch on the
throat; auriculars of the same color. Chin, white. Breast, orange or yellow-
ish white, and in some specimens marked with elongated spots of black. Abdo-
men, thighs and under coverts of the tail, rufous. Sides and flanks, dusky black;
each feather being banded with delicate transverse white lines, and often uniting
so as to form a band in front, at the junction of the breast and abdomen. In
some specimens this band does not appear, as the dusky black feathers do not in
all cases extend across the abdomen. Tail, light gray slate color, is composed
of twelve faathers crossed by nine white bars; the ends of all these feathers
being tipped with white, except the two centre ones. Legs, yellow. Bill, yel-
low, tipped with bluish black. Length, 14 inches.

178 [October,

Female resembles the male, but its colors are less brilliant and marked.

The young bird has the back and tail of a dusky brown, each feather being
fringed with a narrow border of lighter shade. Primaries and tertiaries, edged
with white. Breast, yellowish white, covered with a broad band of dusky black
extending down to the thighs ; these feathers being often edged with light clay-
ish color. Moustache and auriculars, dusky brown.

I saw this bird twice on the vast plains of New Mexico, near the United
States line, before procuring it, flying over the prairies in search of small birds
and mice, and at times hovering, as is the wont of our common sparrow hawk,
{Tin. sparverius.) We possess little information relative to its habits from those
authors who have written on this bird. It appears to be a resident of Surinam,
Cayenne, Brazil, Chili and other portions of South America, and is used in Chili
for hunting the partridge. Besides this species, the American Ibis {Ibis Mexi-
eannSf) also from South America, comes yearly to incubate in California; and
further researches will doubtless still add to our fauna from that country and
Mexico.

Genus PHALACROCORAX, Briss.

Phat.acrocorax penicillatus. Brandt. Brandt's Cormorant.

The specimens in my collection, captured on the Ferrea Leones Islands, are,
I take it, the same as that described by Brandt under the above title. Not
having the work in which he describes the P. penicillatus, I have resorted, for
the purpose of comparison, to a specimen so labelled, and purporting to come
from North America, in the Museum of the Academy of Nat. Sciences of Phila-
delphia. They tally exactly in their color and markings, though they differ in
size. The tail is greyish black, composed of twelve feathers. Feet, black. Bill,
dusky, but of a lighter color towards base of lower mandible. Gular sac, blue,
and at its base, a gorgelet of dirty white. Plumage of back of head, sides of
neck and to the middle of the back, interspersed with white linear feathers,
varying from two lines to two inches in length. Head, neck and abdomen, black,
with glossy reflections of green and blue. Back, black, with glossy green re-
flections, each feather being margined with a narrow fringe of bluish black.

Dimensions of the Academy's specimen. — Length, 24 inches. From flexure to
tip of wing, 10 inches. From point of bill to angle of mouth, 3j inches. Length
of outer toe, 3 3-8ths inches ; of second toe, 3£ inches ; of inner toe, 1 j in.

Dimensions of my specimen. — Length, 28 inches. From flexure to tip of wing,
Hi inches. From point of bill to an^le of mouth, 4 in. Length of outer toe,
3| in. ; second toe, 3| in. ; inner toe, \\ in.^

The bill in my specimen is stouter, the gular sac extends further down the
throat, and the bare space around the eye is larger. Both specimens are in full
spring plumage.

Late in June, these birds were quite numerous at the west end of the island,
and did not appear to associate with the other species; but flocking together on
the most elevated rocks, passed the after part of the day in a state of repose, the
morning having been employed in pursuit of fish, upon which they prey. This
bird was not incubating at that period, as was the P. Townsendii and P. splen-
dens.

Genus ACTIDURUS, Bonap.

Actidurtjs n^vius, nobis. Mottled Grass Plover.

Form. — Bill, slender, as long as the head ; culmen, straight ; sides, compressed
towards the tip, which is slightly curved ; nostrils, linear. Wings, pointed,
reaching to the end of the tail, the first primary being the longest. Tail, long,
broad and rounded, the central feathers longest. Tarsae and toes long. Claws,
short and acute.

The feathers of the upper parts, black in their centre, with broad margins of
light yellowish brown. Primaries, brown, the ends being black, narrowly tipped
with white. Under surface, white, becoming mottled with black 2J inches from
their termini, which there change to a grayish hue. Under wing coverts, black,
spotted with a very faint yellowish ochre and tipped with white. Under parts,

1854.] 179

pale yellow ochre, the feathers bordered with faint white; those of the breast,
near the pinion of the wing, having in their centre a linear spot of black. The
lower part of abdomen and vent are of a much paler hue than the breast. Tail,
brown on its upper surface, the two middle feathers having a bronzed tinge, the
others being tipped with yellowish white, followed by a black band; under sur-
face, grayish, the inner vanes being mottled with minute brown spots. Bill,
black. Feet, light yellow. Length 7a inches.

While riding on the prairie near San Antonio, my attention was called to this
bird from its lesser size than Bartram's Tatler, (Actidurus Bartramius,) which
there abounds. It ran nimbly on the ground among the grass in search of in-
sects, uttering, when disturbed, a weak tweet, two or three times repeated.
The birds of this genus, unlike the Tringae, (which congregate in large flocks,
showing a preference for the sea shore.) migrate in small parties, resorting to
the fresh water ponds and streams of the interior, or seek their food on the broad
grassy plains, and run with great celerity. If alarmed, they fly with rapidity,
making wide, circuitous sweeps before alighting. When wounded, they take to
the water, swimming with facility and often diving to escape danger. The nest,
formed of grasses and containing four eggs, is placed on the ground which has
been previously hollowed out. When disturbed during the breeding season, the
female, flying a short distance from her nest, throws herself on the ground, flut-
tering along as if wounded, and thus decoys the intruder into following her away.
Once at a safe distance, she takes to wing, returning to her home by a circuitous
route.

Genus PODICEPS, Lath.
Podiceps Californicus, nobis . California Grebe.

Form. — Size, small. Bill, slender, slightly curved upwards. Wings, short :
first quill of primaries, slightly longest; secondaries, short ; tertiaries, longer,
nearly equal to the primaries. Tarsae, flattened ; feet, large.

Color. — The entire upper parts of a deep, sooty brown, darkest and nearly
black on top of the head and the back. Neck, almost encircled with grayish
white, and in front with an indistinct band of grayish brown. Sides and flanks
tinged with brownish gray. Under parts, silky white and near the vent having
a sullied appearance. Under wing coverts, white. Some of the shorter pri-
maries, of a cinereous brown, faintly tipped writh white. Secondaries, white,
of which a few have their outer webs brown. Bill, dark, tipped with lighter
horn color. Feet, dark green. Length, 12 inches.

At first sight this bird appears very closely allied to the P. cbrnutus and P.
auritus, but on comparing them, marked differences are at once perceived, both
in size and form. I observed this grebe on the inland fresh water ponds, as well
as on the sea shore, where it was abundant, passing its time on the water, in
pursuit of insects and small fish, with which, on dissection, I found its stomach
filled. Having procured it only during the winter, I am unable to describe its
spring livery, and between the two seasons there is much difference of plumage
in this genus.

Genus PODYLYMBUS, Lesson.
Podylymbus lineatus, vohis. Lineated Diver.

Form. — Size, small. Bill, short and strong; nostrils, conspicuous. Wings,
short ; the 2d primary the longest ; secondaries, short ; tertiaries, longer than
secondaries. Feet, large.

Color. — Entire upper parts, dark reddish brown. A white line from base of up
per mandible, under the eye, and running down the neck, succeeded by another
under it of reddish brown. Spots at the base of under mandible, reddish brown.
Throat, white, marked with a few obscure spots of reddish brown. Lower
neck, in front and upper part of breast, pale reddish brown, with which the
sides and flanks are also tinged. Other under parts, silky white, the lower
portion of abdomen and vent, mouse color. Quills, dark cinereous; secondaries,
tipped with white. Bill, horn color. Feet black. Length, 11 inches.

180 [October,

This bird I procured during the summer, but it is found on the fresh
water courses and marshy lakes of California throughout the year. The nest, com-
posed of a few loose straws 01 rushes, is placed on the ground, near the edge of
the marsh, and contains four eggs of a dirty white color.

Description of four new species of Kivostemum.
By John Le Conte.

The genus Kinosternum, as defined by the latest writers on Herpetology, is
described as follows : Head subquadrangular, pyramidal ; cranium with only one
rhomboidal plate; jaws a little hooked, papillae under the chin. Sternum oval,
moveable, both anteriorly and posteriorly on a fixed piece, furnished with eleven
plates, wings short, narrow, subhorizontal, the axillary plate very large, the in-
guiual still larger. Vertebral scuta slightly imbricate. Tail long, in the males
unguiculate.

A comparison is made of this genus with Staurotypus, to which it in reality
has some affinity, but not so much as M. Dumeril supposes. It, indeed, does not
fall into the same group when the Testudinata are properly arranged, but the
Staurotypus, as will be shewn hereafter, is extremely different and has a mani-
fest relation with the Emysaurtts. M. Dumeril slates that the elastic ligaments
which retain the two moveable portions to the fixed intermediate part 'of the
sternum, are situated, one under the suture of the pectoral and abdominal scuta,
and the other under these la,st and the pectorals. Now it must be observed that
the moveable portions of the sternum are not in every species joined by a liga-
ment to the middle or abdominal piece; in many it is only the anterior one which
is, and which of course turns as upon a hinge ; the posterior portion is joined by
a suture, which is only moveable in the same degree as any other portion of the
bony frame of other animals which is articulated in a similar manner, its movea-
bility depending in a great degree on the length of the teeth of the joining surface,
in others the anterior portion is joined partly by ligament and partly by suture,
the posterior one by suture only, and therefore not so moveable as in other in-
stances.

In young subjects this capacity for motion in the so-called valves of the
sternum is more apparent, but as they advance in age it gradually diminishes,
until in some the three pieces become, as it were, soldered together. In those
species where there are really two valves with ligamentous junctions, the box
of the shell can be entirely closed, and this connects them in some degree with
Cistudo, but this has the sternum joined to the shell by a membrane, whereas
in Kinosternum the same thing is effected by bony commissures from prolonga-
tions of the abdominal portion.

The peculiarities of the sternum will allow the species of this genus to be ar-
ranged in three groups. 1st. Those in which it is truly bivalved, and closing
entirely the aperture of the cell. 2d. Those in which although the sternum is
wide, it by no means closes up the carapace, and is only furnished with an an-
terior valve joined to the abdominal portion, partly by ligament and partly by
suture, yet fully moveable as if the ligament was extended along the whole of
the hinder margin, the posterior valve united by a suture which admits of more
or less motion. 3d. The sternum with two joints, both of them completely
sutural. In these the different parts are frequently as immoveable as in an Emys.

The following description of the genus Kinosternum is offered writh the hope
that it contains all the distinguishing characteristics possessed by the animals,
and that it will be sufficient to separate them from all others of the Testudinata.

Kinosternum. — Chin with from two to six papillae or warts. Vertebral scuta
more or less imbricate ; marginals twenty-three, sternal eleven in number.
Sternum composed of three separate pieces, of which the abdominal or interme-
diate one is immoveable, the anterior one turning on a partially or entirely liga-
mentous hinge, and the posterior articulated to the same piece either by a liga-
ment or by a suture, and consequently either freely and entirely moveable, or
only more or less imperfectly so. The wings which connect the sternum to the

1854] 1S1

shell are sometimes long and narrow, sometimes short and broad, but always
proceeding only from the abdominal piece. The shorter the wings the more
nearly can the shell be closed up by the sternum. The inguinal plate is long
and generally tolerably wide ; the axillary much smaller and narrowed anteriorly.
The feet are palmate, the fore feet with plicas or folds or transverse scales on
the outer side, the hind feet with as many on the inner side and a lew smaller
scales near the heel. The tail is sometimes furnished with papillae andsometimes
naked, often with a nail at the end and as often unarmed : this nail in no instance
being distinctive of sex.

The species embraced in the last group would by some be considered as be-
longing to the genus Staurotypus. and by others to Steinothaerus, to neither of
which does it bear but a very slight resemblance.

The sternum of Staurotyjjus is, as it were, cruciform and pointed before and
behind, the anterior portion consisting of but two plates, formed of the gular, the
brachial, and the pectoral united, and joined to the abdominal by a ligamentous
hinge, the two anal ones likewise being united into one so that the sternal scuta
are only seven in number. The whole contour of the animal reminds one of the
Emi/ia/cnts. As for the Sternothasrus it is exclusively an African genus, and is
remarkable for having no nuchal plate, and thirteen sternals, there being three
gnlars, those with the brachial and pectoral forming an anterior valve, which is
joined to the abdominal piece by a ligament, and of course is moveable, the rest
of the sternum is as fixed and immoveable as that of an Emys. The figure of an
animal of this genus in Dumeril's Herpetologie represents the wings as project-
ing from the pectoral and abdominal scuta, in which case the anterior portion of
the sternum would not be moveable.

I shall now proceed to describe all the species of Kinosternum which I have
been nble to examine, giving minute details of those which I consider new, and
shorter or diagnostic descriptions of such as have been described before.

Gro?rp 1st. Consisting of those with bivalved sterna, the valves joined to the
abdominal piece by ligamentous hinges.

Kinosternum longicaudatum. Testa indistincte 3-carinata, elliptica, convexa,
dorso depressiusculo, postice retusa. margine angusto, nullo rnodo dispanso,
sterno cistam omnino occludente, postice profunde sed anguste emaruinato, scuto
vertebrali primo ad nuchale, marginale primum, et secundi partem anteriorem
appositum, vertebralipostremo solum ad marginale postremum. Cauda unguicu-
lata, ungue lato et obtuso.

Habitat in America meridionali. Spix, Rept. Bras. p. 17, tab. xii.

The carinae on the back of the shell are rather indistinct, and without doubt,
in older individuals, are not perceptible at all. This species is considered by
Dumeril as the Testndo scorpioidea of Linnaeus, which determination we shall
presently see is erroneous.

K. scorpioi/les. Testa ovali modice convexa, dorso fortiter, lateribus naodice
carinata, margine declivi, scutis posterioribus vix latioribus. Sterno utrinque
rotundato, integerrimo. Cauda acute unguiculata.

Hah. in America meridionali Surinami : unde a Dom Dr. Hering receptum.

Head and neck grey, mottled and reticulate with black, upper jaw slightly
hooked. Shell oval, moderately convex, strongly carinate, on the vertebral
line, slightly so on each side, margin obliquely declivous except in the middle,
where it is perpendicular. First vertebral plate triangular, with the apex trun-
cate and the base angled; second, third and fourth hexagonal, with all the sides
nearly straight ; fifth triangular, with the outer posterior angle obliquely truncate,
and applied to the penultimate marginal, which is scarcely wider than that which
precedes it, in consequence of which the posterior lateral is nearly trapezoidal.
Margin acute all round, the plates oblong. Sternum elliptical, rounded at each
end, entire, not closing up the shell entirely; wings short, inguinal plate large,
scarcely narrowed anteriorly. Tail furnished with a sharp nail.

Length 5.7, height l.G, width 4 inches, sternum 4.8 long.

The above description appears to me to answer better to the Testudo scorpi-
oides than any other which I have seen. On account of the many varying
opinions concerning it, I have given a more detailed description than would

182

[October,

otherwise have been necessary. The species is thus described in Gmelin's
edition of the Systema Naturae, vol. 1, p. 1041. T. scorpioides. Palmis ungui-
bus, 5 plantis 4, fronte callosa triloba, cauda unguiculata. Hab. Surinami.

Testa nigra, ovali, oblon_;a, dorso quasi angulis 3 obsoletis, scutellis dorsi
figura clypeorum nobilium {heraldic shields). Caput anterius tectum callo, qui
posterius trilobus est, plantarum digitis externis muticis, ungues acuti, cauda
incurva.

The indistinctness of the dorsal carinas makes me conclude that by the expres-
sion " quasi angulis tribus obsoletis " is meant their rather imperfect develop-
ment. I may not be right in this, for the description is scarcely sufficient to
decide the question. Were it not for the great respect every naturalist ought to
" feel for the great master,

" Qui cunctos superat quod aut fuerunt
Aut sunt, aut aliis erunt in annis,"
it would be as well to strike out of our books this name, as well as many others
scattered through his works.

M. Dumeril considers the longicaudatum of Spix, as well as his brevieauda-
tum, synonymous with this species. The two above-mentioned species are very
different from each other, and have but a slight resemblance to the scorpioides.
An attentive perusal of the tedious and oratorical descriptions of the Brazilian
traveller shows this.

K. Mexicanit7n. Testa ovali valde convexa fusro-lutescente vel nigricante ;

Head and neck above black, beneath yellow reticulately spotted with black,
jaws yellow, the upper one hooked and entire. Chin with four small warts,
only visible in young individuals. Fore legs above dusky, spotted on the ante-
rior side with yellow, beneath brown inclining to dusky, with four plica? or
large transverse scales on the upper side. Hind legs of the same color, with
four large and broad scales and numerous small ones near the heel. Tail short,
dusky, naked, with a rather sharp and long nail. Shell brownish dusky varied
with yellowish or altogether yellowish, the plate with a few indistinct, concen-
tric striae, which in young ones are more numerous and more distinct, and ac-
companied by others radiating from behind, regularly oval, very convex and
elevated, strongly tricarinate, so as to form two deep and wide channels on the
back : very declivous on the sides and on the margin all round. Vertebral
plates elongated and imbricate, the first triangular, with the apex truncate, and
the base somewhat angled, applied to the nuchal and first marginal only ; the
second, third, and fourth urceolate-hexagonal; the second and third emarginate

lateral, and the posterior side bearing the same relation to the anterior; the fifth
heptagonal, the two anterior faces very long, the posterior lateral short and per-
pendicular to the two basal, which are straight ; in young specimens this plate
is simply triangular, with the apex truncate. The first lateral plate is unequally
triangular, the lower side curved, second and third very long, pentagonal, the
fourth quadrangular with the posterior base widely emarginate, so as to give the
figure another side, which thus becomes pentagonal. Nuchal plate small, wider
at base ; all the other plates oblong and four-sided, except the penultimate, which
is twice the height of the others, with its upper face rounded, so as to emargi-
nate the posterior basal angle of the last lateral, and is applied on the upper
half of its posterior side to the last vertebral, giving that plate its pentagonal
form. Sternum large, yellow, the sutures black : oval, entire, rounded at both
ends, the plates in young ones concentrically and radiatingly striate, entirely
closing up the box : gular plate large, triangular ; pectorals irregularly foursided,
the anterior face longer than the lateral; brachials triangular; abdominals
nearly square ; femorals triangular with the apex truncate, and the base rounded;

rangular, the outer side a little curved ; femorals quadrangular, the inner side
much shorter than the outer, posterior side oblique, outer side curved, the ante-
rior straight, the posterior exterior angle projecting a little beyond the caudals
which are right-angled triangular with the base rounded.

Length 4.4, breadth 2.1, height 1.3 : sternum length, 3.7- tail 1.4.
This species, which has the shell much less elevated than any other which I
have seen, appears to be intermediate between this group and the next, so much
so, that I long hesitated where to place it. The points of resemblance, however,
whieh it had in common with the pennsylvanicum being more numerous than
those which belong to the orforatum, led me at last to arrange it with the former.
I may have been wrong in doing this, but if so, there is not much harm done.
The K. sonoriense was brought by my son along with many other interesting
animals from Tucson in Sonora; there can be but little doubt of its being found
likewise in California.

Group III. Sternum narrow, subcruciform, valves joined to the abdominal
portion of the chest by sutures, the lateral teeth of which are so large as to
admit of but little motion, especially in the posterior one; wings long and narrow
without any groove on the inner part, tail unarmed.

It is remarkable how this species has been shifted from one genus to another,
until it may be found arranged under six different genera, and divided into four
species. It does vary considerably as regards the mobility of the sternum, and
the form of the dorsal pottion of the shell, which although generally carinate is
sometimes perfectly flat in the middle; specimens in all respects intermediate
may be found. The anterior valve of the sternum cannot be moved more than
so as to form an angle of 20° with the abdominal line, the posterior much
less.

Besides these, there are four species described by others which I have never
seen, namely, K. hirtipes Wagler. descript. et icones. tab 630. K. brevicau da-
tum Spix. Rept. Braz. p. IS, tab. xiii. K. cruentatnm Cat. Mus. Jardin des
plantes, and K. Doubledayii Gray, Cat. Brit. Mus.

In the imperfect monograph of the Tortoises of the United States, published
in the Annals of the Lyceum of Natural History of New York for the year 1829,
I complained that no arrangement of these animals had yet been offered to the
world which I could consent to adopt. This defect has not yet been remedied,
nor since then have the various suggestions offered by different naturalists been
at all satisfactory. Every scheme for the arrangement into families and groups,
has evidently not been founded on natural and philosophical principles. Most
writers on Herpetology appear to have devoted their time, not to the dis-
covery of the affinities of the objects they were describing, but to changing the
names of the genera and the species, and to making sppcies out of the slightest
varieties; thus clogging the science with useless and absurd synonyms.

The simplicity of my arrangement, which divides the whole order into four
great families, and-these again, when necessary, into groups, will 1 hope recom-
mend it to notice. I owe this arrangement, in a great degree, to the suggestions
of my son.

I add a list of American species of Testudinata, as far as they have yet been
described; many undoubtedly yet remain to be added to it, as few have been
received from Texas, California and Oregon. I have omitted the sea tortoises
because we know nothing about such as are found on our coasts. All the
synonyms which 1 have been able to collect are here set down. This will serve
to show the state in which the science of this branch of Herpetology is at present.
as tar as relates to our country.

I have in the following Catalogue considered the Testudo polyphemus as the
T. Carolina of Linnaeus and Gmelin, and the T. Carolina of authors as the T.
clausa of the latter. My reasons are these : The original description in the
12th edition of the Syst. Naturae, vol. i. p. 352, is as follows :

Testudo Carolina. Pedibus subdigitatis, testa gibba, cauda nulla. Test,
pedibus digitatis, calloso-squammosis ; testa ovali, subconvexa, scutellis planis,
striatis, medio punctatis. Gron. Zooph. 17, No. 77. T. tessellata minor caro-
liniana. Edw. Av. tab. 205, (undoubtedly the Clausa ;) Seba. Mus. 1 tab. 80 figs.
Test, major terrestris americana, (which is represented as 9 inches long.)

To this Gmelin adds : Caput subobtusum, squammis obtusis undique tectum.
Pedes squammis orbicularis obtecti, antice unguibus 5 postice 4 subulatis, acu-
minatis validis armati. Cauda brevissima. Scutum ovale, subconvexum antice
lunulato-excisum margines acuti nee serrati. Scutella lata ad margines striis
cincta, centro punctis excavata. Sternum acuminato-truncatum postice bifidum.
Erasing the words in italics, this is a tolerable description of the large American
land tortoise, and Gmelin certainly had it in view when he made his addition to
the original description. His expression, "Sternum antice truncatum postice
bifidum," together with the scaly head, prove this. The scuta of young animals
of this species are deeply marked with concentric striae, and have a nearly
square area in the centre of each, which is deeply and coarsely punctate. The
name of Polyphemus which has been given to it, means nothing; that of Carolina
is much more fitting; and as for the other species which has been called Caro-
lina, nothing can be more appropriate than Clausa.

It will be observed likewise that I have called the Cistudo Blandingii of Hol-
brook, Lutretnys meleagns. About the generic name there can be no dispute;
but as for the specific name, my reasons for referring it to a species already
described are these. The Testudo meleagris of Shaw, Naturalist's Miscpllany,
vol. iv. p. 144, has been considered as identical writh the Lutremys Europoea,
and is always quoted as a synonym of it. Shaw tells us that his animal came
from America; the other is, I believe, exclusively European. Both species are
remarkable for having the shell more or less covered with small yellow spots;
in the first these are irregularly scattered over the surface, in the latter they
regularly radiate from a centre on each scutum ; the shell is also less convex.

In the Catalogue of Amphibia in the collection of the British Museum, and in
that of the Jardin des Plantes, the following species of tortoises are mentioned
as coming from the United States. In the English Catalogue are described
Emys rivulata, E. scripta, E. Holbrookii, E. macrocephala, and E. Bennetii.
Not having these, and knowing that the descriptions must have been taken from
dried and faded specimens, or from such as were bleached by long immersion in

190 [October,

alcohol, 1 do not hesitate to pronounce them as having no real existence as
distinct species, or at most as being slight variations from others well known
and long ago determined.

The Kinosternum Doubledayii, however, forms an exception. Tt appears to he
certainly a new and hitherto undescribed animal, although what Mr. Gray says of
it is scarcely sufficient to distinguish it. M. Dumeril's E. labyrinthica seems
to be nothing more than E. hieroglyphica of Holbrook, slightly varying in the
disposition of the marks and lines on the shell ; his Kinosternum cruentatum
is probably not from this country; it is a well marked and distinct species.

The following species, retained in most of our books, ought to be struck out.
In Schcepff, Testudo tricarinata, a young animal of some Kinosternum; T.
cinerea, a young picta; T. scripta, a young serrata or reticulata; T. rostiata, a
young Trionyx. And from Linnaeus, Syst. Nat., T. membranacea, which is
likewise a young Trionyx ; T. scabra, — the description has been made from an
immature specimen, which, if full grown, might have been smooth ; T. carinata ;
T. sulcata; and, finally, T. squamosa, which is not a Chelonian.

Observations on the Vespertilio leporinus of Linnaeus.
By John Le Conte.

Our associate Dr. Woodhouse, some time ago gave me for examination a
species of Bat found by him in the province of Honduras, which is undoubtedly
the Noctilio dorsatus of Geoffroy de St. Hilaire, the Vespertilio leporinus of
Linnaeus, i. p. 47, although the description of " the illustrious Swede " is rather
short and imperfect. Schreber vol. i. p. 163 tab. 60 describes and figures it as
a Noctilio retaining the Linnean specific name. Wagner, in his supplement to
the work of this last author vol. 1 p. 451, calls it N. dorsatus and considers it
the same as the albiventris of Spix. Sim. et Ves. Brazil tab. xxxv. fig. 2 and
3, and the N. affinis of D'Orbigny Voy. vol. iv. p. 42 p. 12. The N. unicolor
of Wagner is probably the same. Indeed the author observes, that it only differs
in color from the other species which he describes ; which is a matter of very
little consequence in any of the Vespertilionidse. Every species of this family
is so variable in this respect as to forbid its being taken as a criterion of differ-
ence. There will therefore be but one species of this genus, and for the name of
this we must revert to Linnaeus and resume the old name of leporinus, although
this appellation was founded in error, the upper lip not being cleft, but in recent
specimens covering the incisors. In dried animals it shrinks and becomes drawn
up in such a manner as to leave the upper fore teeth exposed, and to represent a
very bad case of hare lip.

The animal from which the following description was taken, was in its most
perfect state of development ; at that period of its life when it would be called
neither young nor old. It certainly had but twro upper incisors nor was there
any appearance of there ever having been any others ; in their shape they re-
semble canines, and like them are furnished with an interior lobed calcaneum.
The lower incisors are deeply emarginate and may in some instances be taken
for four distinct teeth.

The upper fore teeth of Cheiropters offer a very interesting subject for inves-
tigation, whether what are so-called are in reality incisors, or not more properly
canines. It is now generally allowed that no teeth ought to be called incisors
unless they spring from the intermaxillary bone; now whether in those animals
where there is no nasal bone and the front of the upper jaw is excavated, and this
excavation reaching to the end of the os frontis, they can be said to have any
os intermaxillare, I have not been able to determine. In the frugivorous bats
which have regular incisors in the upper jaw, the cranium entirely wants this
frontal excavation, and is furnished with nasal bones in as much perfection as
any other mammal. The determination of this point must be left to others ; it
is sufficient that I have hinted at the circumstance. It appears to me that some
species of Taphizous may belong to this genus ; not however having specimens
to compare I cannot pronounce positively. The generic essence of our animal,

1854.] 191

exclusive of the teeth is the peculiar form of the alar membrane, which on the
sides extends only to the middle of the tibia, and in the tail being shorter than
the interfemoral membrane and in having its extremity free by passing through
it near the middle.

There are very good representations of this animal in Schreber and in D'Or-
bigny. The figure in Seba vol. i. pi. Iv. fig. 1, referred to by authors, has nothing
to do with it.

In order to remove any difficulty which may hereafter occur in the determina-
tion of this species I add a detailed description, observins that very little reliance
ought 1o be placed on the color.

St. Hilaire and Wagner, N. albiventris Spix, N. affinis D'Orbigny, N. unicolor
Wagner.

Fur short and soft fulvous a little paler beneath, back with a very conspicuous
narrow stripe of a paler and yellowish color from the base of the head to the
root of the tail. The hair of the back occupies a triangular space the base of
which lies between the shoulders and the apex reaches to the tail, leaving the
sides naked. Beneath the whole body is covered with hair. Face black: nose
broad, flat, emarginate, sulcate on the top ; nostrils somewhat tubular and pro-
jecting; upper lip tumid confluent with the nostrils, hanging down and its de-
pendant sides so placed as to form a wide excavation below the part which
covers the incisors ; it is not however cleft nor resembling a hare lip (unless it be
shrunk and contracted upwards by the drying of the parts) lower lip very tumid,
three lobed the lateral lobes recurved and crenate on their edge. Chin with a
small semicircular appendage and four folds diverging from it. Cheeks with
four small warts, each furnished with two bristles. Ears rather long, oval, blunt
pointed, outer edge with four or five transverse plica? the lower part with an up-
right rounded lobe ; tragus small with a small branch on the inner side and four
blunt teeth on the outer. Membrane thin, black, naked, not reaching as in most
other bats to the carpus of the hind feet but ending about the middle of the tibia,
on the under side it is whitish for a considerable space near the body, around the
tail and along the hind legs: at the thumb, on the under side of the membrane on
each side of the innermost figure is a small pouch or cavity formed by a narrow
appendage or supplementary portion of the membrane which proceeds from the
joint and runs down the wing for a short distance. Interfemoral membrane in-
cluding the tail, broad rounded at the end with a small tooth on each side about
one quarter of the distance from the middle. Tail not half as long as the inter-
femoral and projecting from the middle of the membrane for about one fifth of
its length. Hind legs stout, feet very long toes with parallel claws very long
and very much hooked calcaneum bordering the membrane for the greater part
of its length.

Length of head and body 4 inches, head 1.2, extent 22.7, length of interfemoral

On TJrnatella gracilis and a new species of Plumatella.
By Joseph Leidy, M. D.

In the Proceedings for November 1851, (page 321), I published the description
of what I then suspected to be the coencecium of a new genus and species of
fresh water bryozoid polyps, to which I gave the name of JJmatella gracilis.
Since then I have examined this body and find my suspicion was correct ; and
TJrnatella proves to be the most beautiful of the fresh water polyzoa which has
yet been discovered. I have made drawings of the species, and propose hereafter
to give a full description of it; and at present will simply give its diagnosis.

TJrnatella, Leidy.

Cancecium consisting of a series of segments up to eighteen in number, and
forming free, semi-erect, curved stems, attached only by the base of the lowest
segment. Segments, excepting the three last ones, simple, urniform ; the ante-
penultimate and the penultimate oblong, with simple or compound branches of

192 [October,

the same form ; the last segment or active polyp is campanulate and is supplied
with cylindrical, ciliated arms arranged in a circle around the mouth.

Urnatella gracilis, Leidy.

Stems single, or in groups up to six in number, attached at the lower ex-
tremity by means of a sienna colored granular substance. Urniform segments
.225 m.m. long by .18 m.m. broad, becoming smaller towards the free end of
the stems ; body portion of each urniform segment translucent whitish, with
sienna colored transverse striae and punetae, and having on each side near the
bottom a rounded process, the remains of former branches ; the narrow top and
bottom portion of the segments brown in color and annulated. The antepenul-
timate and penultimate segments and their branches oblong, translucent. Polyp
.225 to .45 m.m. long, campanulate ; expanded mouth circular, the diameter
equal to the length of the body, surrounded by fourteen cylindrical, ciliated, re-
tractile arms. Stems up to 4 m.m. in length.

Habitation. — On the underside of stones in the river Schuylkill below low
water, in Philadelphia city.

Plumatella vesicularis, Leidy.

Ccencecium radiating and branching, attached, colorless and transparent; each
segment slightly dilated and much broader than the protuberant orifices of exit.
Length of the segments about 1. m.m., breadth 1 m.m. Animal colorless. Ova
oval lenticular, (with an annulus but without spines.)

Habitation. — Found in the Schuylkill river with the preceding, on the under
side of flat stones.

Remarks. — This species of Plumatella is as limpid as the water in which it
lives ; and it resembles rows of colorless vesicles with a whitish line passing
through their axis. Frequently it is observed with rows of imbricated blackish
eggs instead of the latter line. Patches are found from a quarter of an inch to
two inches square.

the head in that figure are represented as all of the same size, and the markings
upon the body are not the same. It has no resemblance to the Horatta Pam of
Russell, Indian Serpents fig. 11. It is well characterized by the larger scales
upon the vertex. But two species of Echis have been heretofore described.

Characteristics of some Cartilaginous Fishes of the Pacific coast of North

America.

By Charles Girartj.

1. Cestracjon francisci, G. — The largest of these specimens now before us,
and measuring nearly two feet, bears a very strong resemblance to C. Phillippiy
though of a somewhat more bulky appearance. The bony ridge, above the eye,
is much more developed, and the fins are larger also. The posterior margin
of the caudal is bilobed instead of being rounded : an emareination correspond-
ing to the top of the vertebral column. The anal is placed farther back ; its tip
projecting beyond the anterior margin of the inferior lobe of the caudal. The
posterior extremity of the ventrals extends beyond the anterior margin of the
second dorsal. Color, above yellowish grey, darker in the young; beneath light
yellow. Small roundish black spots are spread all over the body and fins.

Collected by Lt. W. P. Trowbridge, U. S. A., in the Bay of Monterey, Cal.

2. Triakis semifasciatum, G. — This species is closely allied to T. scyllhim,
from which it differs by a more backward position of the mouth or else a more
developed snout. The chagrin which covers the surface of the skin is more *
acute, giving to the fish a more prickly aspect. Color above olivaceous grey,
lighter beneath ; yellowish under the head and throat. Dorsal region marked
by transverse bands of deep black, with spots of the same hue between the bands,
and also beneath them, along the sides of the body. A black spot exists at the
base and upper surface of the ventrals and pectorals. The caudal is spotted all
over, whilst the dorsals and anal are so only at their base.

Specimens were collected near Presidio, in the Bay of San Francisco, Cal., by
Lt. W. P. Trowbridge, U. S. A.

3. Spinax (Acanthias) suckleyi, G. — Specimens about twenty nine inches
long. Snout very much flattened, elongated, and subconical in its outline when
viewed from above. Eyes very large, elongated and placed immediately in ad-
vance of the mouth. Five branchial apertures well developed. Mouth large.
Dorsal fins moderate ; spine of anterior dorsal rather small. Pectorals very
large and expanded, concave upon their posterior margin. External margin of
ventrals rounded. Inferior lobe of caudal deeply emarginated ; upper lobe long
and lanceolated. Color above of a dark grey with a few small whitish spots;
beneath, under the head and belly, dull yellowish ; farther back, of a light
greyish hue.

Collected at Fort Steilacoom, Puget Sound, W. T., by Dr. Geo. Suckley,
U. S. A.

4. Rhinobattjs producta, Ayres, in Proc Cal. Acad. Sc. I. 1854. — A male
specimen, thirty eight inches in total length, brought this species to our know-
ledge. The rostral distance, from the eyes forwards, is of a much lighter hue
than the* rest of the body. A blackish band exists along the middle of the back,
with diffused blotches upon the sides, and a double band of the same color along
the middle of the snout.

Collected either at Presidio or Monterey, Cal., by Lt. W. P. Trowbridge,
U. S. A.

5. Raja binoculata, G. — Transverse diameter, from tip of one pectoral fin
to the other, greater than the longitudinal, from tip of snout to the extremities
of the ventrals. Snout tapering and rounded anteriorly. Eyes moderate ; orbit
surrounded with spines. A spine upon the dorsal line, near the origin of the
trunk. Tail longer than the body and head together, slender and flattened most
of its length ; provided above with a series of spines extending from its origin
to the base of the first dorsal fin. Second dorsal within a short space of the first
and approximating the tip of the tail. Ground color olivaceous brown ; snout
dull whitish. A large subcircular black ring at the base of pectorals enclosing
a large subcircular black spot. At a short distance behind these may be seen a
much smaller and more obsolete subcircular dark ring, clouded within with

1854.] 197

blackish. Beneath dull yellowish ; external margin of ventrals blackish. Dor-
sal fins olivaceous; extremity of caudal blackish with a lighter margin.

Collected by Dr. A. L. Heermann,at San Francisco, Cal., while attached to the
Pacific Railroad Survey under Lt. R. S. Williamson, XL S. A.

ATHERTNIDiE.

This family heretofore composed of the single genus Atherina, having been
made on our part the subject of much research, is now understood by us in the
following manner. The

Genus ATHERINOPSIS, Girard,

Which we have recently established, is to receive such species as have no
palatine teeth, with both jaws equal, and the snout more or less rounded.

Atherina menidia, Linn., and A. notata, Mitch., will come under this denom-
ination, alongside with A* calif omiensis, Girard. The

Genus BASILICHTHYS, Girard,

is characterised by the protrusion of the upper jaw beyond the lower; adding
to that feature small teeth on both jaws, none on either the vomer or palatines,
the intermaxitlaries constituting the upper arcade of the mouth, with the maxil-
laries placed behind them, and the upper surface of the head scaly ; including :

4. Basilichthys microlepidotus, G. — Atherina microlepidota, Jen. Zool. of
Beagle, iv. Fish. 1842, 78. PI. xvi. fig. 1, 1 a. 1 b. — Guich. in Gay, Hist, de
Chile, Zool. II. 1848,253.

Inhabits the fresh waters of Chili.

And also Atherina laticlavia, Cuv. & Val. ; A. argentinensis, Cuv. & Val. j
A. macrophthalma, Agass. ; A. bonariensis, Cuv. & Val. and A. lichtensteinii,
Cuv. & Val. Finally the

Genus HETEROGNATHUS, Girard,

Is based upon the elongation of the lower jaw which projects considerably
beyond tbe upper one. There are either no teeth on the palate or else they exist
in a very rudimentary state only.

Atherina humboldtiana, Cuv. & Vax.., and A. vomerina, Cuv. & Val., will,
for the present, constitute this genus.

card-like teeth. Pharyngobranchials covered with similar asperities. Eyes
rather small, situated on the upper surface of head. Opercular apparatus spine-
less. Branchial apertures continuous under the throat. A spine at the external
margin of the pectoral fins. Skin scaleless.

Notice of some Fossil Bones discovered by Mr. Francis Am Lincle, in the banks

of the Ohio River, Indiana.

By Joseph Leidy, M.D.

Through the kindness of my friend, Dr. J. G. Norwood, of New Harmony,
Indiana, I have had the opportunity of examining a collection of fossil bones,,
which were obtained by Mr. Francis A. Lincke, from the banks of the Ohio
River, near the mouth of Pigeon Creek, a short distance below Evansville,
Indiana. The bones are usually found in this locality sticking in the bank,
when the wrater in the river is low.

The specimens are thoroughly impregnated with oxide of iron, which also
erves as a cement to adhering pebbles, sand, fragments of Unios, and shells of
she species of JSlelania canaliculata, Pahi.dina- 2>onderosai etc.

200

[November,,

The collection contains bones of the following animals :—

Megalonyx Jeffersonii, Harlan.

a. Two tibial diaphyses of the left side of young individuals.
h. A vertebra dentata.

c. A. fragment of an os calcis.

d. A metacarpal and a metatarsal bone.

e. An ungual phalanx.

Bison Americanus? (fossilis).*

a. A fragment of a cervical vertebra.

Cervus Virginianus (fossilis).

a. Proximal half of a tibia.

b. Distal half of a tibia.

e. Proximal half of a metacarpal bone.

d. Proximal and distal halves of two metatarsal bones.

e. Portions of two scapula?.

/. Proximal portion of a first rib.

g. The mutilated cranium of a doe.

h. The superior portion of the cranium of a buck ; the antlers having been
shed.

i. Three portions of as many lower jaws of different ages. One contains the
back five molars very much worn away ; a second contains the last two molars
a little worn; and the third contains all the molars, but the last temporary one
has not been shed, nor is the last true one protruded. All these specimens cor-
respond in size with the same parts of large individuals of the existing Certnis
virginianus, and have the same form ; and they probably belonged to the same
species. Besides these specimens, fossil bones of a deer not larger than the
Cervus virginianus have been found in association with bones of the Megalonyx,
Mastodon, &c, in the vicinity of Natchez, Mississippi. In the cabinet of the
Academy there are several specimens from this locality, consisting of a portion
of a lower jaw, a fragment of an antler, and the posterior and inferior portions
of two crania.

Eqtjus Americanus, Leidy.
a. The last dorsal vertebra.

Tapirus.

a. An inferior back molar tooth of an old individual. The crown is much
worn and the fangs are long, spreading, and thickened. It is larger than in the
recent Tapir americanus, and belongs to the supposed extinct species which I
have designated as Tapirus Hay sit.

Canis prim-Evus, Leidy.

This name is proposed for a species of wolf, which I suppose to be indicated
by a specimen, in Mr. Lincke's collection, of a left upper maxillary bone con-
taining the posterior five molars, all of which are nearly entire except the
penultimate one. The fragment, however, only differs from the corresponding
part of the recent Canis lupus of Europe and its American congeners, in being
rather larger (about one sixth), and in its having slight variations in several of
the molar teeth. Certain naturalists may regard the fossil as an indication of a
variety only of the Canis lupus, and of the correctness of such a view I shall
not attempt to decide. Naturalists have not yet settled among themselves the
question of how far characters of a specific value may be obtained from the
skulls and teeth of many genera. Most naturalists regard the Canis lupus, of
Europe, and the Canis oceidentalis and many other wolves of America as of the
same species. Certainly they possess no important osteological differences, but
the same may be said of the grizzly bear, the polar bear, and the brown bear, or
of the horse, the ass, and the zebra, or of the lion, the tiger, and the panther,
etc., etc. Those who have attempted to define a species, I think, have gene-

rally given too much value to a mere convenient word, with which naturalists
empirically designate groups of organized beings possessing characters of com-
parative constancy, so far as historic experience has guided them in giving due
weight to such constancy.

The question of the origin of species, whether from a single pair or from a
plural stock, whether by ascent from the lowest form of life, in gradually di-
verging series, or whether through innumerable miraculous interpositions, 1
think is entirely independent of the former question.

To return to the fossil ; the maxilla has the same form externally as in the
corresponding bone of the recent wolves with which I have compared it. The
infra-orbital foramen is on a line vertical to the interval between the third and
fourth molar teeth, which is slightly farther back than in any of the skulls of
recent wolves examined.

The penultimate molar is less concave posteriorly than in our recent speci-
mens ; and its antero-posterior diameter internally is greater in relation to the
same diameter externally ; in other words, the tooth internally is less narrowed
than in recent wolves. It is also broader in the antero-posterior diameter when
compared with its transverse diameter. Its basal ridge externally is more
abrupt and is slightly mammillated at its border. The second and third molars
have their basal ridge internally more developed, which is also the case with the
internal oblique ridge descending towards the cusp anteriorly.

The principal measurements of the fossil, in comparison with those of the
corresponding part in recent wolves are as follows :

Dr. Wetherill called the attention of the members to the experiments
of Dr. Stenhouse upon the action of charcoal on animal substances in
promoting their rapid destruction, a fact first noticed by Mr. Turnbull,
of London. In the experiments of Dr. Stenhouse, small animals were
covered with powdered charcoal, and the soft parts were speedily de-
stroyed. No offensive odor was noticed, although the experiments were
conducted in the laboratory. Dr. Wetherill suggested the use of this
agent in the preparations of the skeletons of small animals.

Mr. Cassin stated that at the present time, and for several weeks past,
the white-winged Crossbill (Loxia leucoptera) has been exceedingly
abundant in the neighborhood of this city, and noticed the fact that this
had been the case, notwithstanding that the weather had not been more
rigorous than usual at this season. This bird has not appeared here
until the present month, since the winter of 183G-7, when it and other

204 [December,

northern birds were very abundant. As yet, the bird alluded to has
not been ascertained to be accompanied by other species, but is more
abundant than during its visit in 1836-7. During an excursion in New
Jersey, a few miles from Philadelphia, Mr. C. stated that he saw not
only boys shooting crossbills in large numbers, but killing them with
stones, which their frequenting low pine trees, and their apparent entire
want of acquaintance with danger, rendered not difficult. They, in fact,
manifest the utmost simplicity of habits, showing even no signs of alarm
at the report of the gun, and continue quietly searching for food without
regarding the death of their companions.

A collector of this city recently shot seventy-eight specimens in the
course of one morning, and Mr. Drexler, lately employed by the Academy
as taxidermist, shot twenty-seven specimens this day. It would appear
from the unsuspicious manners of these birds that they have migrated
from regions not settled by the white races of men, and their appearance
here in such large numbers may be considered as demonstrative that the
winter in the north either commenced unusually early, thus preventing
the maturity of the buds on which they subsist, or that it has been of
great severity.

An Abstract of Experiments upon the Physical Influences exerted by hiving
Organic* and Inorganic , Membranes, upon Chemical Substances passing through
than by Endosmose.

By Joseph Jones.

The phenomenon of endosmose is coeval with that of life. All organized
beings spring from organic cells. Each cell is a chemical laboratory ; the mate-
rials for its nutrition, growth, and elaboration all pass through its walls by en-
dosmose. What is true of the organic cell, is also true of every living organ-
ism, however simple or complex, because all its acts of nutrition, secretion, and
growth, are carried on by organic cells. These facts show the important bear-
ing of endosmose upon physiology and pathology, and demonstrate the absolute
necessity of studying and understanding its phenomena, and developing, as far
as possible, all its physical laws.

A true knowledge of these can only be gained by careful, laborious, and nu-
merous experiments.

Experiments upon Living Animals, shoioing that their Membranes exert a
Physical Influence capable of changing the molecular arrangement of Chemi-
cal Substances in solution, passing through them by Endosmose.
Immersed the belly and lower extremities of a large spring-frog, in a strong
solution of the chloride of calcium, and allowed it to remain for an hour ; then
washing it carefully with water, immersed its lower extremities in a strong so-
lution of the oxalate of ammonia. It remained in this solution for one hour,

1854.] 205

when it was again carefully washed and placed in the solution of the chloride of
calcium, where it remained for a similar length of time. Finally, it was re-
moved from this, back to the solution of the oxalate of ammonia.

During the course of the experiment, which lasted four hours, the frog gradu-
ally became weaker and more inactive, and finally died in the solution of the
oxalate of ammonia in which it was last placed. The specific gravity of the
solution of the oxalate of ammonia was much less than that of the chloride of
calcium, consequently the object in moving the frog from one solution to
another, was to obtain as large a deposite of the oxalate of lime within its
blood-vessels and tissues as possible, by promoting the actions of imbibition,
endosmose, and exosmose.

As a general rule, the rapidity of the action of endosmose is proportional to
the difference of the densities of the exterior and interior fluids. The effects of
this action, or rather of the membranes, upon the chemical substances passing
through, will be manifested by the change of physical form exhibited by the
precipitate of the oxalate of lime.

Immediately after the frog had been removed from the solution of the oxalate
of ammonia, an incision was made below and to the side of its sternum, into the
cavity of the thorax and abdomen. The heart was found still pulsating. The
blood-vessels beneath the skin, upon the surface of the stomach and intes-
tines, in the muscular fold of the peritonoeum, and between the kidneys, ap-
peared thoroughly injected with blood, as if the animal had died of violent in-
flammation of all these parts.

The blood from the heart and lungs was first examined under the microscope,
in which, with a magnifying power of 210 diameters, were seen innumerable
minute cubical particles, floating amongst the large elliptical blood capsules. In
the fibrous tissue between the epidermis and pectoralis major muscle, square
plates, cubical crystals, and parallelograms were seen, together with minute
particles, the largest of which appeared to be cubes.

The mesenteric fold of the peritonoeum contained the same equi-lateral, equi-
angular plates, and cubical crystals. In the fascia of the thigh, besides numbers
of these, there appeared, also, beautiful octohedral crystals of the oxalate of
lime, similar in all respects to those formed when the intestines of a raccoon,
(Procyon lotor,) were filled with a solution of the chloride of calcium, and im-
mersed in a solution of the oxalate of ammonia.

When the eggs of the frog were mashed, and their contents spread out on a
glass slide and examined under the microscope, they contained multitudes of
equi-angular plates, aud cubical crystals of the oxalate of lime.

It is probable that the exterior fluids passed through the anus and cloaca into
the oviducts and ovaries, and finally by endosmose into the eggs themselves.

In the fibrous tissue of the walls of the abdomen, in addition to the cubes and
octohedra, and equi-lateral plates, there appeared, also, delicately formed dumb-
bell and ellipsoidal crystals.

When the plantar fascia of the foot was cut through, from the incision flowed
a fluid resembling the liquor sanguinis mixed with a little blood, which, under a
magnifying power of 210 diameters, contained beautiful octohedral and dumb-
bell crystals of the oxalate of lime.

This experiment was repeated with slight variations, as to the length of the
time, and the density of the fluids, and in every instance, without any exception,
the results were the same.

In one instance, the deposit formed within the blood and tissues of the frog,
assumed the form of delicate dumbbell and cruciform crystals of the oxalate
of lime. Figure 1. represents the appearance of these crystals and their rela-
tive size, when compared with the blood corpuscles. In another experiment
the blood from the ventricle of the heart contained large and perfectly formed
octohedra, with a few dumb-bell crystals, while the various tissues and muscles
contained chiefly delicately formed dumb-bells and crystals, and the aqueous
humor of the eye contained octohedral, and comparatively large acicular crystals.

Figure II. represents the crystals from the blood of the heart.

Figure III. those found in the tissues, and between the fibres of the muscles.

206 [December,

Figure IV. the acicular and octohedral crystals found in great numbers in
the aqueous humor of the eye.

We see then by these microscopical examinations, that the oxalate of lime
has assumed forms different in all respects from those of the precipitate thrown
down, when solutions of the chloride of calcium and oxalate of ammonia are
brought into immediate contact. The precipitate thus formed consists of mi-
nute irregular granules. Figure V. represents this deposit. What has changed
the physical form of this deposit ? It has been accomplished, without doubt,
by the action of the membranes upon the chemical substances in solution pass-
ing through them.

Experiments upon the physical influence exerted by mucous membranes, removed
from all vitality •, upon chemical substances in solution passing through litem.

Filled the intestine of a Raccoon, (Procyon lotor), with a solution of the
chloride of calcium, whose specific gravity was 1031, and immersed it in a so •
lution of the oxalate of ammonia, having a specific gravity of 1007. In the
course of an hour the exterior fluids became cloudy, with a white precipitate,
the oxalate of lime. At the end of two days, a copious white deposit had settled
to the bottom of the jar, which, under a magnifiying power of 210 diameters,
presented the appearance of innumerable acicular, rectangular, and irregular
particles, often conglomerated together in great numbers, forming miniature
representations of plants with their branches and leaves. Figure VI. represents
their appearance.

Specific gravity of exterior fluid 1005.

The interior fluid was next examined, the intestine having been punctured
and its contents carefully removed.

Specific gravity of interior fluid 1003.

This marked change of its specific gravity from 1031 to 1003, shows that a
free interchange of the fluids must have taken place. The slight change in the
exterior fluid, of 1007 to 1005, is readily explained, when we consider the fact,
that the exterior was 12, whilst the interior was only 4 fluidounces.

Within the intestines but a small deposit had taken place, in comparison with
that of the exterior fluid. Under the microscope this presented a magnificent
crystalline appearance, differing wholly from that of the exterior fluids, and also
from that formed when solutions of the chlorides of calcium and oxalate of am-
monia are brought into immediate contact.

The appearance of this magnificent microscopical object is represented in
figure VII.

Amongst the crystals there were no less than seven well defined regularly formed
varieties. We recognize the octohedral and dumb-bell crystals, as the form in
which the oxalate of lime almost invariably occurs in the urine, not only of man,
but also of other animals, and even in that of birds.

Does not this experiment indicate that the peculiar forms of the oxalate of
lime, occurring in urine, may be the result of the physical action of the base-
ment membrane of the tubuli uriniferi and its secretory cells ?

The tissues of the intestine were next examined.

The cellular tissue was not equally injected ; in some places there was scarce-
ly any, while in others there was a very abundant deposit.

In all places the mucous membrane appeared free from any deposit of the oxa-
late of lime. It was found difficult, however, to decide this question by the mi-
croscope, on account of the difficulty of separating the fibrous tissue completely
in which occurred a copious crystalline deposit.

This is not the only instance ; out of numerous examples, we will select only
two.

When the bladder of a raccoon (Procyon lotor) was filled with a solution of
the bichloride of mercury, and immersed in a solution of the iodide of potassium,
a brilliant red crystalline deposit of the biniodide of mercury took place upon
the exterior, whilst upon the interior a light yellow mass of lozenge-shaped
crystals of the protiodide of mercury was precipitated. In this case also the
mucous membrane appeared free from any deposit.

1854.] 207

When the intestines of a raccoon were filled with a solution of the acetate of
lead, and immersed in a solution of the bichromate of potassa, the deposit upon
the exterior consisted of innumerable small irregular granules, while that upon
the interior consisted of beautiful stellate crystals.

When a sheep's bladder was rilled with a solution of the oxalate of ammonia,
and immersed in a solution of the chloride of calcium, no deposit took place in
the exterior iluid, whilst a precipitate of the oxalate of lime fell in the interior
flufd.

The appearance of this under a magnifying power of 210 diameters, is repre-
sented in figure VIII. Within the muscular and fibrous coats of the bladder
this deposit presented the same appearance. The fact that solutions of certain
chemical substances will pass through a membrane in one direction, but not in
another, might be illustrated by many examples.

The stomach of a raccoon was filled with a solution of the bichromate of potassa,
and immersed in a solution of the acetate of lead ; a copious deposit of the chro-
mate of lead took place in the exterior fluid, whilst none whatever occurred in
the interior; it retained its natural color and appearance. The results were in
all respects the same when the intestines of this animal were treated in a similar
manner.

When the stomach was treated in this manner a deposit took place only upon
the interior. When the oesophagus of a large rattlesnake (Crotalus adamanteus),
was treated in a similar way, only a small deposit occurred in the exterior fluid.
Filled the stomach of a raccoon, and a portion of the intestines of a large
rattlesnake with a solution of the iodide of potassium, and immersed them in a
solution of the bichloride of mercury ; in both cases a copious deposit occurred
upon the exterior, whilst little or no precipitate fell in the interior fluid.

These facts are due to one of two causes. Either certain chemical substances
in solution exert an influence upon mucous membranes, changing their minute
anatomical structure, and thus destroying their power of carrying on the physical
phenomena of endosmose andexosmose; or else mucous membranes possess a
power of choice, as it were, dependent upon their physical constitution, allowing
one fluid to pass through in one direction, but not another fluid holding a different
chemical substance in solution in an opposite direction. When a portion of the
small intestine of a sheep was filled with a solution of the nitrate of lime and
immersed in a solution of the oxalate of ammonia, a copious precipitate of the
oxalate of lime took place in the exterior fluid, which under a magnifying power
of 210 diameters was found to consist of innumerable octohedral crystals of dif-
ferent sizes, also a few dumb-bell crystals. The appearance of this deposit is
represented in figure VIII.

In the exterior deposit the octohedra were about one hundred times more nu-
merous than the dumb-bell crystals.

In the interior fluid a deposit of the oxalate of lime had taken place, which
under the microscope presented the appearance represented in figure IX. The
entire deposit consisted of innumerable minute and delicately formed dumb-bell
crystals, with here and there an octohedral crystal. In the interior fluid, unlike
the exterior, there were over a hundred dumb-bell crystals to one octohedral
crystal. Minute octohedra, and delicately formed dumb-bells, were found within
the meshes of the fibrous tissue. By comparing this experiment with the former
ones in which solutions of the same chemical substances were used, we are
forcibly taught the following laws.

l?t. Mucous membranes from the same relative part of the bodies of different
animals, exert different physical influences upon the same chemical substances.

2d. Mucous membranes from the same animal, but from different parts of
the body, exert different physical effects upon solutions of the same chemical
substances'.

3d. The physical influence exerted by the membrane is not the same in
endosmose and exosmose ; it differs with the direction of the current.

A very important question now presents itself for our consideration. May
not this change of form in the precipates be due to the presence of some animal
substance or fluid, as fibrin, blood, albumen, or serum, and no to the physical

208 [December,

action of the membranes. To determine this point a series of careful experi-
ments were instituted with the following substances; albumen, fibrin, yolk of
hen's egg, warm blood, cold blood, putrescent blood, warm serum, cold serum,
putrescent serum, and urine. In no case did the presence of these substances
produce a crystalline deposit of the oxalate of lime. Each experiment was per-
formed in several different ways, and under different circumstances ; sometimes
the densities of the solutions of the chloride of calcium and oxalate of ammonia
were varied, at others the temperature and conditions of the foreign body. But
one result attended all these experiments — no crystalline deposit. In many
instances we have mingled the interior and exterior fluids, in both of which
crystals had been produced by the action of the membrane, and in every case
the precipitate of the oxalate of lime thrown down consisted of irregular granules
without any crystalline form whatever. Does not this prove conclusively that
the simple presence of the different membranes did not cause the change of the
physical form of the precipitate?

The next question which presented itself was, whether dry membranes exert a
physical influence upon substances passing in solution through them, capable of
changing their physical forms ? To determine this point we performed several
experiments with dry membranes, with solutions of the chloride of calcium and
oxalate of ammonia, varying the relative positions and densities of the fluids in
each experiment. In no instance was a regular crystalline deposit obtained.
In only one experiments, two or three octohedral crystal occurred in the midst
of millions of irregular particles.

All our experiments, thus far, prove that dry membranes exert little or no
physical influence upon chemical substances in solution passing through them.
Our next subject was to ascertain the influence of inorganic septa, during the
endosmotic action. In our experiments we used thin vessels of baked clay.
These were filled with a solution of the chloride of calcium and immersed in a
glass jar containing a solution of the oxalate of ammonia. The relative posi-
tions and densities of these fluids were also changed. In no instance did we ob-
tain a regular crystalline deposit. So far then as our experiments go, we are
able to assert, that inorganic septa do not exert a physical influence upon chemi-
cal substances passing through them, capable of changing the arrangement of
their molecules.

Experiments 7cpo?i the physical influence exerted upon chemical substances in solu-
tion, as they pass through the cell walls of vegetables.

Immersed the cut end of a stalk of Indian corn in a solution of the chloride of
calcium, and allowed it to remain for 18 hours, at the end of which time it was
removed and placed in a solution of the oxalate of ammonia, in which it re-
mained for a similar length of time. When thin slices of the corn-stalk were
examined under a magnifying power of 210 diameters, a crystalline deposit of
the oxalate of lime, was found to have taken place within the hexagonal cells of
the vegetable, which presented the appearance represented in Figure IX. This
differs widely from the deposit formed when solutions of the oxalate of ammo-
nia and chloride of calcium are brought into immediate contact. The precipi-
tate thus formed consisted of irregular granules.

The crystals deposited within the cells of the corn, differed widely also
from those formed when the intestines of a raccoon or a sheep were filled
with solutions of the oxalate of ammonia, and immersed in solutions of the chlo-
ride of calcium.

Immersed sections of different lengths of the stem of a young and verdant
benne plant, in a solution of the acetate of lead, and then transferred them to a
strong solution of the proto-sulphate of iron. When thin sections were exam-
ined under the microscope, beautiful square and lozenge-shaped plates had crys-
tallized in all the hexagonal cells.

When .the broad thick leaf of an endogenous plant was placed alternately in
solutions of the same chemical substances, a crystalline deposit took place
within its cells, which differed in form from that within the cells of the benne
plant. Different vegetables were immersed in different chemical solutions,

1854.] 209

which when mingled produced a deposit of irregular granules, and in every in-
stance a regularly crystalline deposit took place within their cells.
It is unnecessary to do more than recapitulate the following results.

1. Cell-wTalls, like animal membranes, exert a physical influence upon the
chemical substances held in solution passing through them. This physical in-
fluence is capable of altering the arrangement of the molecules of the precipi-
tate formed within the cells, so that the precipitate which under ordinary cir-
cumstances consists of irregular granules, under the influence of the endosmodic
action assumes a regular crystalline form.

2. The cells of different vegetables, like different animal membranes, change
in different manners the arrangement of the molecules of the same substance.

It may yet be demonstrated, by experiment, that cells in the same plant,
having different offices, elaborating different products, may exert a different
physical influence upon the same chemical substance. Or, in other words, the
crystalline deposit of the same substance, will vary in physical properties with
different cells.

In conclusion we would state that we are still investigating this subject, and
hope to be able to substantiate, by numerous experiments, performed under
every possible circumstance, all the laws and facts asserted in this brief abstract
of experiments.

Remarks on the question of the identity of Booiherium cavifrons with Ovibos moschatus

or 0. maximus..

By Joseph Leidy, M.D.

In the Zoology of the voyage of H. M. S. Herald, the author, Sir John
Richardson, in speaking of an extinct species of ox, characterized by me under
the name of Bootherium cavifrons starts a question, of which I think there is not
the least necessity. On page 120 of his excellent work, he remarks, " Dr. Leidy
includes no fewer than twelve crania, all more or less mutilated, and dug up in
the valley of the Mississippi, in his species named Bootherium cavifrons, to which
he refers Dr. Dekay's specimen; and a comparison of his fig. 2, pi. iii. with the
same view of the cranium of the musk-ox in pi. iii. of the ' Zoology of the Herald,'
leaves no reasonable doubt of the fossil species being quite distinct from the re-
cent one. The accessory trochlea? of the occipital condyles are fully developed in
the fossil skull, and many other peculiarities of Ovibos may be discerned in the
figures, so that Bootherium and Ovibos are evidently very closely allied. A ques-
tion now arises whether the dentata above referred to as the foundation of
the proposed palaeozoic species Ovibos maximus may not be a relic of Dr. Leidy's
cavifrons, and this might, without much risk of mistake, be decided in the affir-
mative, were it certain that the Siberian crania mentioned in the ' OssemeLS
Fossiles' were identical in speeies with those imbedded in the drifts of the Mis-
sissippi ; but as yet the evidence for such an extension of the ancient range of
cavifrons is wanting. The size of Dr. Leidy's specimen of cavifrons does not
exceed that of the skull of an aged musk bull, and the dentata of maximus is of
corresponding dimensions. If the discovery of a dentata of the musk-ox type,
and of suitable size, in the valley of the Mississippi, should hereafter fully
establish the identity of cavifrons with maximus, it may be necessary to ascertain
which of the two appellations was first made public."

That Bootherium is closely allied to Ovibos, as declared in my " Memoir on the
Extinct Species of American Ox," page 12, there is no doubt ; but that the two
genera are distinct I think is proved by the former possessing an important
character, which does not exist in the latter nor in ar.y other genus of Bovidae. The
character to which I allude is the large lachrymal fossa? cr larmiers situated in
front of the orbits, as in the Cervidae, and which are represented in fig. 1, pis.
iv., v., of the memoir above referred to, in both species of Bootherium.

" That the Siberian crania mentioned in the ' Ossemens Fossiles ' " are not
,' identical in species with those embedded in the drifts of the Mississipj i," I

210 [December,

think any one will grant who will take the trouble to compare the figures of
the " Siberian crania," in the works of Pallas,* Ozeretskovsky,f or Cuvier,J
with my figures of Bootherium cavifro?is. • The former are indistinguishable
from the figures given of the crania of the recent Ovibos moschatus, while the
latter has no deep fissure separating the bases of the horn cores, but these are
confluent and form a huge process covering the entire length and breadth of the
frontal bone.

Sir John Richardson has himself, in page 22 of his work, considered the " Si-
berian crania" as belonging to the Ovibos moschatus ; and in the above extract
has stated there 13 " no reasonable doubt of the fossil species," [Bootherium cavi-
frons) ''being quite distinct from the recent one" [Ovibos moschatus). Conse-
quently, he has decided that Bootherium is a different animal from the species to
which the " Siberian crania" belonged. Therefore, it appears to me, when Sir
J. R. subsequently says, " A question now arises whether the dentata above
referred to as the foundation of th© supposed palaeozoic species Ovibos maximus,
may not be a relic of Dr. Leidy's cavifrons, and this might, without much risk of
mistake, be decided in the affirmative, were it certain that the Siberian crania
mentioned in the ' Ossemens Fosslles' were identical in species with those em-
bedded in the drifts of the Mississippi, but as yet the evidence of such an ex-
tension of the ancient range of cavifrons is wanting," the question had
already been decided that " the Siberian crania" were not "identical in species
with those embedded in the drifts of the Mississippi."

Sir J. R. then says, te The size of Dr. Leidy's specimen of cavifrons does not
exceed that of the skull of an aged musk-bull, and the dentata of maximus is of
corresponding dimensions." If this be the case I would ask, as the lidentata of
maximus " was found in the country of the " musk-bull," and is of the same size
as the corresponding bone in that animal, what evidence is there that it does not
belong to it ?

Under these circumstances "the discovery of a dentata of the musk-ox type,
and of suitable size, in the valley of the Mississippi," would by no means " estab-
lish the identity of cavifrons with maximus" but would rather tend to show the
greater ancient range of the Ovibos moschatus.

In regard to the time at which the appellations cavifrons andmaximus were
made,public I deem it of trifling importance to science, but I may take the pre-
sent opportunity of stating that the name Bootherium cavifrons was proposed in
the number of the Proceedings of this Academy for May and June 1852, which
was distributed the following month, therefore three months previous to the ap-
pearance of the " first part of the Herald's Zoology."

In conclusion I may add a list of what appear to be the species of American
ox, recent and extinct.

1. Bison Americanus, (recent and fossil). The fossil certainly not the Bison
priscus ? Richardson.

2. Bison latifrons, Leidy. For synonyma refer to page 8 of Mem. on Ext.

Richardson, but probably it may be Bison latifrons.

Descriptio?is of the species of Trox and Omorgus inhabiting the United States.

By John L. LeConte, M.D.

Trox Fabr.
A. Thorax incequalis prrzcipne bicostatus.

1. T. S o n or ae , oblongus niger, thorace latitudine fere triplo breviore, ir-
regulariter grosse punetato, inaequali, disco elevato bicostato, lateribus late
rotundatis, elytris costis quatuor suturaque elevatis haud interruptis, sptis sor-
didis brevissimis tesselatis, interstitiismuricato-punctatis cicatricosis, tuberculis
parvis uniseriatis notatis. Long. *38.

One specimen, Tucson, Sonora. This species is very similar to the next, but
the sides of the thorax are less rounded, being almost straight near the base ;
the furrows of the elytra are distinctly tuberculate, and the general form of the
body is narrower. Nevertheless, a larger series of specimens may prove these
differences to be of no value.

2. T. al t e r n a n s , oblongus, niger, thorace irregulariter grosse punctato,
latitudine fere triplo breviore, lateribus modice rotundatis, elytris costis quatuor
suturaque elevatis haud interruptis, setis-sordidis brevissimis tessellatis, inter-
stitiis muricato-punctatis, transversim cicatricosis, tribus internis simplicibus,
quarto costula intermedia notato. Long. -37.

Kansas Territory and New Mexico. The head is scarcely tuberculate,
densely punctured with the clypeus rounded, not margined ; thorax two and a
half times wider than long, moderately rounded on the sides, ciliate with yel-
low bristles, irregularly and coarsely punctured, unequal, with the middle of the
disc strongly elevated and bicostate, the intermediate furrow being divided by
a slight transverse elevation about the middle. Elytra oval, truncate at base,
finely serrate on the sides, with four elevated uninterrupted costae, which are
tessellated with short yellowish bristles, and alternate shining spots ; suture
elevated ; the three inner spaces are broadly concave, with irregular transverse
elevations, and sparingly marked with small muricate punctures, arranged nearly
in four series, but not so closely placed as to render the arrangement obvious ;
in some directions the transverse elevations seem to indicate a row of tubercles,
but this is also very indistinct ; the fourth space is marked with an indis-
tinct interrupted costa, forming a row of tubercles ; at the tip of the elytra
all these irregularities fade away, and the ordinary arrangement of striae
may be traced. The capillary striae seen in many species are here en-
tirely wanting:, except in the subsutural space where they may be faintly
discovered. The anterior femora, as in most species, are strongly dilated
and crenulate inferiorly; the anterior tibiae of one specimen from Kansas
are without teeth; in the New Mexican specimen, besides the ordinary
square terminal tooth, there are two small ones at the middle, and some fine
serrations towards the base.

A specimen from Kansas, of smaller size (.35) has the costae of the elytra
less elevated and the interstices less corrugated, so as to present, besides the
very small muricated punctures, two rows of large subquadrate punctures,
nearly as in T. p o r c a t u s , from which, however, it is abundantly distinguished
by the differences in the form and sculpture of the thorax, and by the absence
of the capillary striae of the elytra.

3. T. s o r d i du s, niger, thorace flavo-ciliato, brevissime setoso. inaequali
irregulariter grosse punctato, lateribus late rotundatis, medio modice elevato
bicostato, elytris costis quatuor interruptis, suturaque elevatis brevissime setosis,
postice indistinctis, interstitiis inequalibus bistriatis, tuberculisque parvis uni-
seriatis. Long. *3.

Georgia, New York, Kansas. Smaller than the preceding, with the sides of
the thorax less rounded and the disc less elevated. The second and third costae
of the elytra are more interrupted than the first and fourth, and all are indis-
tinct posteriorly ; when the inequalities of the elytra are less marked, the

18

212 [DECEMBER;

capillary striae appear strongly punctured with an intermediate row of small
distant tubercles. The anterior tibiae are furnished with a broad bidentate ter-
minal process, and one well-marked tooth at the middle ; they are finely serrate
towards the base. The anterior femora are very strongly dilated and crenate
on the inferior margin. The head is somewhat more unequal than in T. alter-
nans.

4. T. po r c at u s, niger, sordidus, thorace longius flavo-ciliato, sordidebreviter
setoso, latitudine duplo breviore, lateribus antice rotundatis, inequaliter punc-
tato, medio bicostato, sutura costisque interruptis elevatis rlavo-setosis, costis
alternis minoribus fere indistinetis, interstitiis punctis magnis quadratis seriatis
stria capillari coniunctis. Long. «4 — #46.
Say, Journ. Acad. Nat. Sc. 5, 193.

Middle and Southern States. The sides of the thorax are straight for three
fourths of their length, and are then rounded to the apex ; the punctures of the
elytra are connected by striae, and the inequalities diminish towards the tip.
The anterior tibiae are serrate towards the base, with one sharp tooth at the
apex: the femora are very much dilated, and hardly crenulate on the inferior
margin. In the form of the thorax this species is allied to T. capillaris,
but in that species the capillary striae of the elytra are much stronger, the costae
are less distinct, forming merely rows of distant penicellated elevations, and
the rows of punctures are not very obvious.

5. T. tuberculatus, obiongus, niger, thorace latitudine plus duplo bre-
viore, lateribus late rotundatis, inaequali, partibus elevatis breviter fulvo-setosis,
dorso elevato, bicostato, elytris tuberculis valde elevatis oblongis brevissime
setosis, quadriseriatim positis, interstitiis parce quadriseriatim murieato-punc-
tatis, suturaque tuberculis parvis uniseriatim notatis. Long. *3 — 37.

Trox serrulatus, Beauv. Ins. 176, tab. 46, fig. 9.

Trox canaliculatus, Say, Long's Exped. St. Peter's 2, 278.

Middle and Southern States, not rare. Besides the apical emarginate process,
the anterior tibiae have only one prominent tooth at the middle ; above this are
some fine crenulations. This species is not much like T. sabulosus of
Europe, with which Olivier compares it, but is the only one known to me that
will agree with the descriptions or figures.

6. T. erinaceus, minus elongatus, subovatus, niger, thorace latitudine fere
triplo breviore, lateribus late rotundatis, setis nigris penicellato, dorso bicostato,
elytris striis distinctis, interstitiis parce muricato-punctatis interstitiis 3, 5, 77
9 tuberculis valde elevatis, oblongis, acutis nigro-penicellatis, serie suturali
paulo minore ornatis. Long. «25.

South Carolina, Mr. Zimmermann. The intervals between the series of large
elevations are marked with a scarcely distinct series of tubercles, hardly
larger than the scattered elevated punctures. The denticulations of the anterior
tibiae are not distinct, but one near the middle is a little more prominent.

7. T.terrestris, breviusculus, ovatus, niger (praecipue sordidus), tho-
race latitudine duplo breviore, lateribus vix late rotundatis, subreticulatim
inaequali, elytris punctis quadratis seriatis, interstitiis alternis elevatis subin-
terruptis, brevissime sordide setosis, alternis (alteris) parce muricato-punctatis^
Long. -21— -24.

Say, Journ. Acad. Nat. Sc. 5, 192.

Middle and Southern States, abundant. The inequalities of the thorax are
less developed than in those above described, and are connected together so as
to give a reticulated appearance ; five of the cells are adjacent to the base, and
three fill up the apex. The anterior tibiae, besides the universally found square
apical prominence, have only one moderate tooth below the middle.

8. T. capillaris, longiusculus, ovatus, sordide niger, thorace parce

Middle, Southern and Western States : the anterior tibiae have a prominent
tooth below the middle and a smaller one above the middle. When the elytra
are very carefully cleaned the elevated lines towards the suture are seen to be
double, while beyond the third series of the larger bunches of bristles, they
vanish entirely, and rows of punctures alone are seen. The inequalities of the
thorax consist of the two entire dorsal costae and a smaller one each side, ex-
tending from the base beyond the middle.

B. Thorax hand intequalis.

9. T. variolatus, elongatus, niger, thorace latitudine duplo breviore,
lateribus antice rotundatis, confertim punctato breviter setoso, late canaliculato
et marginato, elytris striis tenuibus elevatis punctatis, interstitiis fulvo-penicel-
latis, alternatim paulo elevatis, seriebus alternis maioribus. Long. '25.

Melsheimer, Proc. Acad. 2, 137.

Middle States. The sutural series of bunches of bristles is larger than the
one adjacent. The anterior tibiae have two or three very small teeth on the
outer margin. Closely resembles the next, but readily distinguished by the
elevation of the alternate intervals, and by the larger bunches of hair on the
elevated spaces.

10. T. as q u a 1 i s, elongatus, niger, thorace latitudine duplo breviore, lateribus
antice rotundatis late deplanatis, confertim punctato, breviter fulvo setoso, dorso
subcanaliculato, elytris striis tenuibus elevatis punctatis, interstitiis aequaliter
uniseriatim fulvo penicellatis. Long. '25.

Say, new species of insects of Louisiana, (1832).

Middle and Southern States. The anterior tibiae have one small tooth near
the apical prominence, which is bidentate.

11. T. fascifer, elongatus, niger, thorace latitudine duplo breviore, late-
ribus late rotundatis, late deplanatis, confertim subtilius punctato, breviter fulvo
setoso, dorso vix canaliculato, elytris striis tenuibus elevatis subtilius punctatis,
interstitiis aequaliter uniseriatim fulvo penicellatis. Long. *26.

One specimen, San Francisco. Precisely similar in form and appearance to
the preceding, but differs in having the striae of the elytra finely instead of
coarsely punctured : the outer margin of the anterior tibiae above the terminal
bidentate prominence is marked with three small but distinct teeth.

12. T. 1 a t i c o 1 1 i s , minus elongatus, niger, nitidus, thorace latitudine plus
duplo breviore, lateribus magis rotundatis, late explanatis, angulis posticis valde
obtusis, parce setoso, grossius punctato, late canaliculato, elytris striis subtilius
punctatis, interstitiis planis fasciculis minutis nigris uniseriatim ornatis. Long.
•24.

One specimen, New York. Broader than the two preceding, with the sides
of the thorax considerably rounded, so that the posterior angles become obtuse:
the fascicles of the elytra are composed of only three or four short black
bristles, which arise from a somewhat muricate puncture. The anterior tibiae
have three small equidistant teeth, exclusive of the terminal prominence.

13. T. s t r i a t u s , oblongus, convexus, nigro-piceus, nitidus, thorace latitu-
dine plus duplo breviore, lateribus angustius marginatis late rotundatis, sat
dense punctato subcanaliculato, elytris glabris, striis profunde crenatis im-
pressis, interstitiis subconvexis, parce punctulatis. Long. '25.

Melsheimer, Proc. Acad. 2, 137.

Pennsylvania, Rev. D. Zeigler ; very rare. Besides the strongly bidentate
apical tooth, the anterior tibiae are armed with three small teeth : the posterior
angles of the teeth are nearly rectangular.

214 [Decembee,

14. T. atr ox, elongafus, ovafas, niger, thorace latitudine duplo breviore, late
marginato, confertim punctato, breviter setoso, subcanaliculato? lateribus late
rotundatis, elytris striis duplicatis crenatis, interstitiis uniseriatim flavo-setosis.
Long. -33.

One specimen, found near Long's Peak. The setae of the elytra arise from
small murieated punctures. The anterior tibiae are more tiilated than in the
other species; the terminal tooth is very much rounded, and above it are two
or three sinuosities indicating other teeth. The form is that of T. variolatus7
but larger.

Omorgtjs Er«

This genus, described at length in Wiegmannn's Archiv., (13, 111) and referred
to in Erichson's Ins. Deutsch. (925), contains the largest species of our native
Trogidae. It difFers from Trox by the corneous prominent ligula, by the first
joint of the labial palpi being longer than the second, and finally by the terminal
hook of the maxillae being cleft, and the second hook being single. (In Trox
the terminal hook is usually trifid.) As these characters are difficult, certain
differences in appearance may be made use of to separate the two genera. Thus
in Trox the sides of the thorax are strongly ciliated, and broadly regularly
rounded, while in Omorgus the sides are hardly ciliate, and are frequently ir-
regular, and sometimes toothed : the eyes of our native species of Trox
are reticulated, and the posterior tibiae toothed ; while in Omorgus the eyes
are smooth, and the posterior tibiae in our native species without teeth. Of
these habitual characters, reliance can be placed absolutely upon none but the
structure of the sides of the thorax, as according to Erichson, species of Trox
occur in which the eyes are smooth and the posterior tibiae toothless. Our species
may be divided thus :

A. Corpus dpterum ; thorace bullis nitidis or nato,

1. O. texanus, apterus niger, convexus, thorace cataphraeto valde in-
aequali, lateribus rotundatis ante basin subincisis, elytris seriatim grosse punc-
tatis nitidis irregulariter ccelatis. Long. «8.

Eagle Pass, Texas, collected by Mr. Schott, under Major Emory, of the
U.S. and Mexican Boundary Commission, and also by Lieut. Haldeman. This-
species is larger than 0. scutellaris, and the lines of punctures on the elytra are
better marked ; but except in the form of the sides of the thorax, there appears
to be no special difference ; as in that species, the posterior outer angle of the
large four-angled bulla each side of the dorsal channel is produced.

2. 0. scutellaris, apterus niger, thorace cataphraeto, valde insequali?
lateribus rotundatis, elytris seriatim minus distincte punctatis, transversim
ccelatis, interstitiis subquadratis, subaequaliter parum elevatis. Long. *6 — «65»

Trox scutellaris Say, Journ. Acad. Nat. Sc, 3, 23S.

Kansas Territory near the mountains : New Mexico, Mr. Fendler : abundant.

3. O. suturalis, apterus niger, thorace cataphraeto, valde inaequali?
lateribus rotundatis, elytris minus distincte seriatim punctatis, transversim
ccelatis, interstitiis inaequaliter magis elevatis, sutura costata. Long. -63.

Texas Mr. Schott, two specimens. Distinguished from the preceding by the
more elevated and irregular shining spaces of the elytra, and by the suture being
elevated in the form of a eosta.

4. O. umbonatus, apterus niger, thorace cataphraeto, valde inaequali?
lateribus rotundatis, elytris minus distincte seriatim punctatis, interstitiis trans-
versim ecelatis, alternatim magis elevatis. Long. *65'.

Texas, Messrs. Schott & Clark. Also allied to 0. scutellaris, but besides the
inequality of the rows of elevations of the elytra, the four-angled bulla each side
of the dorsal channel of the thorax has the posterior outer angle not produced?
aad almost obtuse. The body is also more elongated.

Trox scabrosus Beauv., Ins. d'Afr. et d'Amer. 175, tab. 46, fig. 4.*
New York, Florida, Texas. This species has entirely the appearance of the
next, from which it seems to differ only by its usually much larger size, and by
the sides of the thorax (excluding the indentation) being rounded instead of an-
gulated, and by the elevated points between the large series of tubercles of the
elytra being much larger, and by some of them forming intermediate series of
smaller tubercles. As in the next there is a sutural series of small tubercles.
This large species is abundant, especially near the sea shore.

6. O. pustulatus, sordide fuscus, vel niger, opacus, thorace valde inaequali,
lateribus medio fere angulatis, pone medium incisis, angulis posticis rotundatis,
elytris tuberculis serie quadruplici et ad suturam positis magis elevatis cata-
phractis, interstitiis parce inordinatim muricato-punctatis. Long. «55 — *6.

? 'Trox tuber culatus\\ Beauv., Ins. 175, tab. 46, fig. 3.

Southern States, not rare. This species agrees very well with Beauvois' figure,
but his insect is said in the text to have been found in Hayti. It is remarkable
that while he mentions that Trox tuberculatus (Olivier) was unknown to him,
he should retain for his own very different species the same specific name.

This species is distinguished (apart from the differences in the elytra) from the
following as well as the preceding species by the sides of the thorax converging
obliquely from the middle to the apex ; the effect of this is to produce an indis-
tinct angle near the middle ; this character in consequence of the gradual curving
of the sides is not seen either in 0. scabrosus or in O. asper.

7. O. a s p e r , niger, sordidus, opacus, thorace valde inaequali, lateribus late
rotundatis, pone medium subincisis, angulis posticis latius rotundatis, elytris
tuberculis magis elevatis cataphractis quadruplici serie ornatis, sutura intersti-
tiisque tuberculis minutis uniseriatim positis, et ordinatim profunde punctatis.
Long. «5.

Georgia, South Carolina, Mr. Zimmermann. The elevated punctures scattered
irregularly between the rows of tubercles, as seen in the two preceding species,
have here disappeared ; the intervals are somewhat unequal, and in each are seen
two moderately regular rows of large punctures, with an intervening series of
small tubercles, which like the larger tubercles are covered with a brown crust.
These small tubercles are, however, scarcely more elevated than the places be-
tween the punctures forming the rows. The lateral incision of the thorax is
much less deep than in the preceding species, and the posterior angles are broader
and less prominent.

8. O. punctatus, griseus, thorace inaequali, lateribus obliquis late rotun-
datis, pone medium subincisis, angulis posticis vix rotundatis, canalidorsali antice
mediocri, elytris seriatim crenato-punctatis, interstitiis parce subtiliter muricato-

Our most abundant species, found from New York to Santa Fe and Texas.
The tesselated spots of the elytra in well preserved specimens afford an excellent
character for distinguishing it : greasy specimens are uniformly black in color,
and in such the absence of tubercles on the elytra, and the less deep dorsal channel
of the thorax may be taken as distinguishing marks. The punctures of the stria?
of the elytra vary somewhat in size; sometimes they are small, deep and well

216 [DECEMBER^

defined ; at other times they are broad and subquadrate, so that the less elevated
interstitial spaces appear transversely rugous : the alternate intervals are some-
times very distinctly, and sometimes hardly apparently elevated, yet with a large
series of specimens these differences shade imperceptibly together. The in-
equalities of the thorax are much less conspicuous than in the following species,
and the four usual posterior tubercles are rather flattened.

The synonym last quoted is not certain, yet as specimens occur in which the
sutural space is more distinctly elevated than the others, it would be safer to refer
it here, than to retain it as a species, without any distinct character. Trox cre-
natus and denticulatus (Oliv.) are described as South American species, and do
not appear to resemble those described under the same name by Beauvois.

9. 0. mors us, sordidus (vel niger) thorace valde inaequali, Iateribus late
rotundatis, pone medium paulo incisis, angulis posticis late rotundatis, dorso
antice valde canaliculato, elytris seriatim crenato-punctatis, interstitiis alterna-
tim modice elevatis, interruptis (subtesselatis) tuberculis nitidis obtusis, alternis
tub^rculis minoribus noTatis. Long. -5 — *55.

Texas and Kansas. Very similar to the next species, and differs principally
in having the sides of the thorax distinctly incised a little behind the middle.
In well preserved specimens, the elytra would probably be tessellated, as in the
preceding species : between the large tubercles are seen rou^h places, as if for
the insertion of short bristles, precisely as in badly preserved specimens of Q.
punctatus : the smaller series of tubercles are sometimes hardly visible. The
inequalities of the thorax are very much elevated, and the four posterior tubercles
very distinct, the outer ones as usual being interrupted.

10. 0. integer, sordidus (vel niger) thorace valde inaequali, Iateribus late
rotundatis, haud incisis, angulis posticis rotundatis, disco antice valde canalicu-
lato, elytris seriatim crenato-punctatis, interstitiis interruptis tuberculatis, alter-
nation magis elevatis. Long. -5 — *53.

Texas and Northern Sonora, near Tucson. As in some specimens the spaces
between the black tubercles are covered with a brown crust, the elytra are
probably tessellate in well preserved individuals. Besides the absence of the
lateral incision of the thorax, this species differs from the preceding by the tu-
bercles of the elytra being more closely arranged, and by the less elevated inter-
vals being more unequal. In one specimen, however, the intermediate rows of
small tubercles are almost obsolete.

11. O. tesselatus, convexus, sordide cinereus, thorace inaequali, Iateribus
magis rotundatis haud incisis, angulis posticis paulo rotundatis, disco antice valde
canaliculato, elytris muricato-punctatis, crenato-striatis, interstitiis paulo con-
vexis spatiis quadratis nigris laevigatis, parum elevatis tesselatis. Long. *61 — '65.

This fine species is contained in the beautiful series of Coleoptera brought by
Dr. Thos. H. Webb from the boundary between Mexico and the United States,
and is labelled " San Diego trip" : for the purpose of completing the present
genus, the description is placed here, though it properly belongs to a paper to be
found below.

The form of the thorax is similar to that of the preceding, but the elevations,
although very sudden, are smaller, and the anterior one is distinctly divided into
two longitudinal ridge?, the outer one, of course, being shorter; the elevations
of the elytra are nearly equal, except the sutural row, which is smaller. The
anterior tibiae are armed with a distinct tooth about the middle.

Some corrections in. the Nomenclature of Coleoptera found in the United States,

By John L. Le Conte, M. D.

During the course of years through which our Coleoptera have gradually been
made known, too often under great disadvantages arising from the limited libra-
ries, and still more limited collections to be found in this country, many species
have been referred to wrong genera, and thus became placed in such relation to

1854.] 217

known species as very much to confuse subsequent investigators. The student
of local faunae alone can be expected to remove these obstacles, which fortunately
are now but few in number. Such of them as have come before my view while
arranging in my collection several families, upon which I am not yet prepared
to publish special investigations, are here presented, in the hope of economizing
time and labor for other entomologists.

Besides these, I have found it necessary to indicate several generic synonyms,
which have been created by want of familiarity with foreign species belonging
to genera not previously known in this part of the globe, or which, from the
fanciful classifications frequently invented in the study of large groups, are so
described as to be irrecognizable, without typical species. It is to be understood
that the corrections here made embrace only such as have not appeared in Dr.
Melsheimer's Catalogue of Described Coleoptera, or in any of the synopses or
monographs published in this country or Europe, so far as known to the author.

1 . Elmis v i 1 1 a t u s Mels. Proc. Acad. 2, 99. Well preserved specimens of
this species, found at Baltimore, which I owe to the kindness of Mr. J. P. Wild,
have proved that the reference to E. 4-notatus Say, made by me in Proc. Acad.
6, 44, is incorrect. The mutilated specimen in Dr. Melsheimer's collection was
insufficient to make known the character of the species, which is larger and nar-
rower than E. 4-notatus, with the sides of the thorax less rounded, and the punc-
tures composing the striae of the elytra smaller and less distant. The color is
yellow, with the head, sides of the thorax, margin and suture of the elytra,
blackish, and the postpectus, femora and tibiae dusky. From E.bivittatus Lee.
it is distinguished by its smaller size, paler color, and by the narrower and less
convex thorax having the sides less rounded.

2. Macronychus lateralis Mels. Proc. Acad. 2, 99, does not differ fromM.
glabratus Say, Journ. Ac. 5, 187.

3. Simplocaria s t r i g o s a Mels. Proc. Acad. 2, 118, (Georissus strigosus
Mels. Cat. Descr. Col. 35) has been shown by me (Proc. Acad. 7,) to be a Syn-
calypta, and very probably European.

4. Cicones marginal is Mels. Proc. Acad. 2, 112, must be referred to
Coxelus.

5. Atomaria cr e n at a |]Mels. Proc. Acad. 2, 114 (Cryptophagus gilvellus
Cat. Descr. Col. 45) belongs to Litargus Er.

6. Phanaeus t o r r e n s Lee. Journ. Acad. 2d, 1 , 85, by the completion of the
series of specimens, proves to be a bright colored, short horned variety of P.
triangularis.

7. Onthophagus n i g e r Mels. is a dark variety of O. Janus.

8. Ochodaeus obscurus Lee. Journ. Acad. 2d, 1, 86, is no Ochodaeus, but
seems related to Aesalus, near which it will form a new genus.

9. Ochodaeus americanus Westwood, Trans. Ent. Soc. London, 2d, 2,
66, is, on the contrary, a true Ochodaeus, but was previously known as Bolbo-
cerus musculus Say, Bost. Journ. Nat. Hist. 1, 178.

10. Scarabaeus splendens Beauv. 89, tab. 26, fig. 2, is referred by Mr.
Chevrolat to Xyloryctes, (Ann. Ent. Soc. Tr. 2d, 18, 641,) but appears to be
really Strategus A n t ae u s 9 •

• 11. Scarabaeus Bos ci Beauv. ibid. fig. 1, is also a Strategus, not described
by Burmeister.

12. Anomala m a r g i n e 1 1 a Lee. Proc. Acad. 7, 81, is the previously known
A. binotata Burm.

13. The species of Tostegoptera described by me, viz., T. cribrosa, ven-
tricosa, aequalis (Proc. Acad. 6,231 and 440) form a new genus distin-
guished by the ligula being deeply and squarely emarginate, while in Tostegop-

218 [December,

tera the same part is subtruncate ; the emargination in T. asqualis is less than
in the other two, but is quite obvious. This genus may be separated under the
name E u g a s tr a.

14. Polyphylla variolosa Harris, is referred by Erichson (Ins. Deutschl.
659) to Melolontha occidentalis Linn., an entirely different species of the
same genus, which is found in the Southern States, and which has the suture
and three vittae on each elytron covered with white hair.

15. Melolontha 10-1 in ea ta Say, a species of the same genus, is closely al-
lied if not the same as the Mexican Polyph. leucogramma Blanch. (Cat. Mus.161.)

16. Atractopterus incongruus Lee. (Trans. Am. Phil. Soc. JO, 454) is
very similar to the European Sericosomus fugax ; the name Sericosomus is
founded upon characters, although recognizable, too slight to be admissible in a
system of rational classification, but as its type coincides with Atractopterus, it
seems proper that the latter name should be suppressed.

17. Pyractomena linearis Lee. Proc. Acad. 5, 336, is P. lucifera Mels.
ibid. 2, 304 ; the latter name I placed incorrectly as a synonym of P. angulata.

18. Pyractomena fenestralis Mels. ibid. 2, 304, is not Ellychnia c o r-
r u s c a, as stated by me (Proc. Acad. 5, 334) but another species of Ellychnia,
allied to E. ni grica n s.

19- Alloeocnemis Lee. Proc. Acad, 6, 232. This must be added to the al-
ready numerous synonyms of Polycaon Lap. which has been passed from
Cleridae to Melyridae, and as in the present instance to Nitidulidae. Its true
resting place is, as indicated by Erichson in Ptiniores, where it approaches on
the one hand Apate, and on the other Lyctus ; a curious species found in Texas
by Lieut, Haldeman completes the chain of analogy in form and sculpture.

20. Triphyllus r u g o s u s Randall, (Cis rugosus Mels. Cat. Descr. Col. 85,)
is Endecatomus reticulatus Mellie, Ann. Ent. Soc. Fr. 2d, 6, 213.

21. Xyletinus sericeus Say, Journ. Acad. 5, 171, belongs to Trypopitys
Redt.

22. Xyletinus flabellicornis Sturm, Cat. (1826) tab. 1 , fig. 7, does not
belong to the family of Ptiniores, nor can I at present indicate where it should
be placed.

23. Tomicus 1 i m i n a r i s Harris, (Ins. Inj. Veget. 78,) found by Miss Mor-
ris to inflict serious injury upon peach trees, belongs to Phloeotribus.

24. Pachyvhynchus Schonherri Kirby, Fauna Bor. Am. 203; Rhinaria
Schonherri Schonh. 7, 2,369, is merely Ithycerus curculionoides Schonh. 1,246.

25. Brachytarsus obsol.etus Schonh. (1839) 5, 167, is Anthribus variegatus
Say, (1826) Journ. Acad. 5," 251.

26. Brachytarsus brevis Schonh. (ibid.) is Anthribus tomentosus Say, ibid.

27. Anthribus coronatus Schonh. (1833) 1, 141, is A. cornutus Say, (1831.)
Curcul. 4.-

28. Anthribus capillicornis Say, (1826,) is Arascerus coffeaB Schonh. (Fabr.)

29. Anthribus 4-notatus Say, (1826,) is A. bimaculatus Oliv. and belongs to
Tropideres.

30. Trichocnemis Lee. (Journ. Acad. 2d, 2, 110) is not sufficiently distinct
from Ergates ; the Californian species must therefore be called E.spiculatus.

32. Tinopus Lee. (ibid. 2d, 2, 19) is the same as Rhopalophora Serv.

33. The genus Argaleus Lee. (ibid. 2d, 1, 319) is founded on defective cha-
racters ; the type A. nitens is congeneric with Leptura monticola Randall,
upon which I founded Evodinus ; the latter genus must therefore be suppressed.

1854.] 219

The second species of Argaleus (Pachyta attenuata Hald.) enters the genus An-
thophylax Lee. Piodes must be united with Acmaeops. Commencing then with
Rhagium, our genera of Lepturidae, having the front oblique, the mentum trape-
zoidal, and the gula emarginate each side of the mentum, may be thus arranged :

1. Antennae ante oculares ; tibiae calcaribus ad apicem sitis ;

a. Sterna gibba ; coxae anticae discretae Rhagium.

b. Prosternum simplex ; coxae anticae contiguae ; oculi integerrimi ;

Mesosternum protuberans Gaurotes.

Mesosternum planum Acmaeops.

2. Antennae vix interoculares ;

a. Tibiae calcaribus ante apicem sitis Toxotus.

b. Tibiae calcaribus ad apicem sitis ;

Oculi mediocres ; elytra postice angustata Argaleus.

Oculi magni ; elytra linearia Centrodera.

2. Antennae interoculares ; oculi intus emarginati ; tibiae calc ad apicem sitis ;

a. Palpi labiales dilatati Anthophylax.

b. Palpi labiales maxillaribus non latiores.

Antennae articulis externis utrinque impressis Typocerus.
Antennae 11-articulatae articulis haud impressis ;

Thorax angulis posticis productis Strangalia.

Thorax angulis posticis haud productis Leptura.

The separation of the last two genera is evidently unnatural. The separation
of Centrodera and Argaleus is also on very slight characters, but as thus far
there is a peculiarity of appearance, which renders each easy of recognition, it
will be more convenient to permit them to remain distinct. The other genera
appears to be entirely natural.

34. Taraxis Lee. (Agassiz* Lake Superior, 237) does not appear different from
Auchenia.

35. Hemophilus f o s s o r Lee. (Journ. Acad. 2d, 1, 92) appears not to be re-
lated to Heliophilus, but to be a new genus near Opatrum ; Opatrum latima-
n us, described at the same time, is also referred incorrectly ; it is allied to and
perhaps congeneric with Leichenum.

36. Pytho pallida Say, (Journ. Acad. 3, 271,) belongs to Adelina.

37. Boletophagus tetraopes Newman, (Ent. Mag. 5, 378,) is Eledona d e-
pressa Randall, Bost. Journ. Nat. Hist. 2, 21 ; the last mentioned name has
priority by two months.

38. Boletophagus silphides Newman, ibid, is on the other hand a species
of Peltis, (!!) so closely allied to P. dentata of Europe, that by Dejean it was
considered identical.

39. In Psorodes Solier (Studi Entom. 167) has placed Helops contractus Beauv.
under the name P. inflata. The same insect was long ago made the type of a
special genus, Meracantha canadensis Kirby, (Fauna Bor. Am. 238.) The name
must therefore be Meracantha contract a.

40. Stenochia gracilis Lee. (Ann. Lye. 5, 150) is allied to Allecula ; the
penultimate joint of the tarsi is lobed, and the ungues are serrate.

41. Mycetochares ruficornis Mels. Proc. Acad. 3, 59, is a Melandryide,
congeneric with Hallomenus luridus Hald.

42. The last named species does not appear sufficiently distinct from H. scapu-
laris Meis. Proc. Acad. 3, 57.

43. Orchesia sericea Mels. ibid, upon which the genus Calasia Hald. is
constructed is a true Scraptia.

44. Scraptia 1 ute a Hald. is not different from S. pallipes Mels.

45. S. a mericana Hald. placed in the Cat. Descr. Col. p. 143, as synony-
mous with the last, is a different species.

220 [December,

46. S. rugosa and flavicollis Hald. do not belong to Scraptia; but 1
cannot find any genus in which they may be placed ; they appear rather related
to some Tenebrionides, than to Melandryades.

47. Anaspis 4-p unctata Say, Journ. Acad. 3, 276, is a true Mordella.

48. Anaspis ventralis Mels. seems to be a variety of A . rufa Say, Journ.
Acad. 5, 244. A. filiformis Lee. Agassiz' Lake Superior 231, is the male
of the same.

49. Anthobates Lee. (Lac. Sup. 231) must be reunited with Anaspis ; the
character upon which I separated it is entirely false ; nor can I account for such
an error of observation.

50. Lytta fulgifer Lee. is merely a dark colored variety of L. N u t a 1 1 i Say.

51. Eugnathus|| Lee. Trans Am. Phil. Soc. (10, 375,) a genus allied to Pana-
gseus, must be changed to M i c r i x y s. The name Eugnathus has been already
twice used in the order of Coleoptera.

Descriptions of new Coleoptera collected by Thos. II. Webb, 31. D., in the years 1850-51
and 52, while Secretary to the U. S. and Mexican Boundary Commission.

By John L. Le Conte, M. D.

Most of the species collected by Dr. Webb, have been already described by
me from other sources, but the remaining nondescripts contain a comparatively
greater number of large and beautiful species than any other collection yet ob-
tained. The localities are mostly given within limits.

Cicindela prae tex tat a, longiuscula, subtus viridi-amea, abdominis lateri-
bus albo-pilosis, supra fusco-cuprea, opaca ; labro albo transversim quadrato, an-
tice subtiliter tridentato, fronte utrinque subtiliter striato, thorace lateribus ro-
tundatis albo-pilosis, latitudine haud longiore modice convexo, impressionibus
tran3versis profundis ; elytris thorace sesqui latioribus modice convexis, limbo
latiusculo albo, intus obtuse dentato, fascia intermedia obliqua longiuscula recta,
subtilius haud profunde punctatis : palpis sexus utriusque testaceis, articulo
ultimo ceneo. LoDg. *45 — -6.

"San Diego to El Paso." By a figure kindly sent me by Prof. Lacordaire,
this species seems somewhat related to C. circumpicta,yet the prolonged oblique
band of the elytra, as well as the thorax, which is not brilliant and not deeply
sulcate, will distinguish it. The species here described appears in general more
related to C. generosa, formosa, &c, but is more elongated in form. The apex of
the elytra is not at all serrate, and in the female each is considerably rounded,
while in the male they are conjointly rounded and the little tooth of the suture
ia more obvious.

Two males found on the " San Diego trip," differ from the type by the more
brilliant coppery color of the upper surface, the more distinct punctures of the
elytra, and by the middle band of the elytra being gradually dilated internally
and truncate, while in the type it is rounded at tip, and not dilated.

Cicindela lemniscata, elongata cylindrica subtus viridicenea, abdominis
lateribus albo-pilosis, supra, cuprea; labro alborotundato, subtridentato, fronte
concavo, utrinque striato viridi-micante, antennis nigris, thorace jrugoso, cylin-
drico, lateribus albo-pilosis vix rotundatis, impressionibus transversis profundis,
disco medio purpureo, elytris thorace vix sesqui latioribus, parallelisapice oblique
rotundatis, densius fortiter punctatis, vitta utrinque discoidali integra alba pone
medium intus obtuse bidentata, et apicem ad suturam ambiente : pedibus palpis-
que testaceis, his apice seneis. Long. *31.

" San Diego trip," one male. This small and slender species is the only North
American one known to me in which the elytra are ornamented with a vitta
equally remote from the suture and margin : the outline of the vitta is straight,

1854.] 221

rendered irregular internally by two slight and obtuse teeth near the tip ; it is
also prolonged around the apical margin to the suture ; the tip of each elytron
is slightly rounded, and the margin is not serrate.

Melanotus e r r o , nigro-piceus, nitidus, mandibulis fortiter rugosis, thorace
capite cum oculis haud latiore, latitudine fere triplo breviore, postice angustato,
angulis posticis obtusissimis valde rotundatis tenuiter canaliculato, lateribus
rotundatis anguste marginatis, basi utrinque late impresso alutaceo, elytris
ihorace haud latioribus strii3 profundis impunctatis, interstitiis fere planis, an-
itnnis palpis pedibusque rufo-testaceis. Long. -57.

One specimen, " San Diego trip." This species, the second discovered in North
America, is considerably larger than A. scaritides Chaud. [Cratognathus scar.
Perty, Amblynathus niger Gray.) which it otherwise closely resembles in general
characters.

Acilius maculatu s, ovalis, paulo convexus, infra ferrugineus, supra niger
nitidus, capite ante oculos, maculaque transversa verticaii flavis, thorace lateri-
bus fasciaque angusta postice concava ad medium interrupta flavis, elytris mar-
gine maculis tribus annexis, alterisque disci (quarum una ad medium prepe su-
turam multo maior) laete flavis, pedibus anterioribus testaceis. Long. -55.

Fem. striolis a basi ad quadrantem elytri singuii extensis. Mas latet.

One specimen from the Copper mines. In this beautiful species there is a
complete absence of the small anastomosing spots seen in our other native spe-
cies. The ground color above is black with well defined bright yellow spots :
those of the head consist as usual of the anterior part, and the transverse verti-
cal spot, which is emarginate anteriorly. The thorax has the sides broadly yel-
low, and two narrow discoidal spots running obliquely outwards and backwards,
so as to form a fascia concave behind and interrupted at the middle. The spots
of the elytra consist of a yellow margin extending nearly to the tip ; joined to it
are three spots, the first extending from the base almost to the middle, undulated
internally and. suddenly dilated at it3 posterior extremity, as if by the addition
of a small spot ; the second is quadrate and placed about the second third ; the third
is at the tip of the yellow margin and is subtriangular, with the apex directed an-
teriorly : there are besides on each elytron two basal spots, the outer of which is
elongated ; two small quadrate spots at the anterior fourth ; a large rounded one
about the middle and near the suture ; a smaller one still nearer the suture at
the posterior fourth, and a small one very near the apex. A small yellow dot
may be seen between the two basal spots, but is perhaps sometimes wanting:
the surface i3 nearly smooth ; the usual series of punctures are distinct, and
from the middle of the base of each elytron to the large spot are scattered a few
short strise as in the females of other species.

Dineutes integer, oblongo-ovalis dorso convexiusculus, supra niger subaenes-
cens, minus nitidus ; elytris obsolete punctatis tenuiter obsolete striatis, postice
coniunctim rotundato-truncatis, vix undulato-emarginatis, subtus niger, pedibus
posticis picescentibus. Long. -61.

One specimen from the Copper mines. From D. vittatus, which it equals in
size, this species is at once distinguished by the tips of the elytra being conjointly
broadly rounded, so as to leave no apparent angle at the suture.

Stethoxus subsulcatus, elongato-ovalis, convexus, utrinque attenuatus,
olivaceo-niger, nitidus, thorace trapezoideo, latitudine plus duplo breviore lateri-
bus vix rotundatis, basi late emarginato, angulis posticis apice rotundatis, ely-
tris obsolete sulcatis, sulcis utrinque obliteratis, lineisque punctorum solitis
tribus notatis ; antennis palpisque ferruginei3. Long. 1.25, lat. *65.

At Camp 7. Still narrower than S. triangularis (Hydrophilus triangu-
laris Say), and readily distinguished by the broad indistinct furrows of the ely-
tra: the furrow next the suture can hardly be seen.

Plusiotis glorio sa supra leete psittacina, clypeo punctulato margino sub-

222 [December,

tili elevato aureo, thorace scutelloque limbo totoangusto aureo punctulatis, ely-
tris parce punctulatis margine laterali vittisque quatuor irnpressis splendidc

vam simulaatibus oraatis, subtus aureo-viridis, commissuris omnibus aureis,
mesosterno subito declivi, vix porrecto. Long. -78 — -92.

Copper mines and at Camp No. 6. This most splendid species belongs to di-
vision II. of Burmeister, (Lamell. 2, 420), but is very different from any described
by him.

Chalepus obsoletus, piceo-nigra nitida, clypeo punctato, emarginato,
thorace subtilissime reticulata, parce punctato, apice coreo marginato, elytris
striis solitishaud impressis subtiliterpunctatis, interstitiis alternis parce subtiliter
punctatis. Long. -82, lat. -43.

One specimen, " San Diego trip." Larger and proportionally narrower than
C. trachypygus ; the striae of the elytra are merely rows of fine punctures. The
pygidium is polished, sparsely and somewhat finely punctured, with a strongly
impressed line running around its posterior margin.

Polyphylla cavifrons, fusco-ferruginea pube squamulosa pallide fusca
parce vestita, thorace lateribus sulco dorsali plagaque utrinque basali densius
pubescente, sat dense minus subtiliter punctato, clypeo (maris) lateribus oblique
divergentibus, antice truncato valde concavo, elytris sutura vittisque angustis
utrinque tribus densius squamulosis, subtus densius squamulosa, pectoribus lana
longissima tectis, tibiis anticis fortiter 3-dentatis. Long. -88 — 1-10.

One male found on the San Diego trip and another mutilated one procured by
Mr. Schott on the Rio Grande. Similar in form and size to P. variolosa Har-
ris, but differs in the clypeus being much more concave, and wider at tip than
at base. The lines on the elytra are only moderately distinct, and the short hu-
meral vitta seen in P. 10-lineata is entirely wanting. From all other American
species known, it differs in having the anterior tibiae of the male (and therefore
also of the female) strongly three toothed, thus belonging to Erichson's division
B. (Ins. Deutschl. 659) with the European P. h o 1 o 1 e u c a Er.

Copris mcecha, nigra, clypeo punctato apice subemarginato, (maris cornu
elongato cylindrico armato) thorace punctato, disci medio laevi, canaliculato
(maris antice retuso emarginato et abrupte declivi, lateribus cornu compresso
valde elevato armato, linea solita elevata submarginali, impressioneque trans-
versa laterali notato) elytri3 striis sat profundis subtilius crenatis, interstitiis
laevibus. Long. *7T.

One male from Camp 14. Allied to C. anaglyptica, but differs by the much
more strongly developed horns, the less dense punctuation of the thorax, and
the deeper elytral striae. From a Central American species known in collections
as C. ChevrolatiijDej., it differs by having all the hollows of the thorax strongly
punctured, and by the clypeus being more distinctly emarginate : it is possibly,
however, merely a northern variety of that species.

Ochodaeus simplex, ovalis convexus, ferrugineus, breviter fulvo-setosus,
punctatus, clypeo haud carinato, transversim leviter sulcato, apice subtruncato,
elytris confertim punctatis leviter striatis interstitiis haud elevatis. Long. «25.

One specimen from the Copper mines. Differs from 0. musculus by the
absence of the transverse carina of the vertex, and by the anterior margin of the
clypeus not being elevated : the teeth of the mandibles cannot be seen.

Ochodaeus striatus, oblongo-ovalis, convexus ferrugineus, breviter fulvo-
setosus, punctatus, clypeo antice subtruncato subtiliter marginato, vertice ele-
vato vix transversim carinato, thorace postice canaliculato, elytris parcius punc-
tatis striis crenulatis, interstitiis paulo convexis. Long. -25.

One specimen from Arispe. A little narrower than the preceding, with the
vertex elevated, but forming rather a transverse tubercle than a carina. The
striae of the elytra are moderately deep, and the intersticesare slightly convex and
rather sparsely punctured.

Long. *95 — 1*4:7.

As a slight testimony of my appreciation of the valuable labors of Dr. Webb
vrhile connected with the Boundary Commission, I have dedicated to him this
very tine species : several specimens were obtained on the journey from San Diego
to El Paso, and also on the San Diego trip. The thorax is about one fourth
longer tran wide, with the sides in the female nearly parallel from the base to
within one fourth of the apex, where they converge obliquely and are slightly
rounded. The posterior angles are very slightly prolonged, and are somewhat
acute, notcarinated. The ecutellum is cordate, wider posteriorly, and emarginate
at each end. The elytra gradually taper from the base, are slightly rounded on
the sides, and suddenly rounded at the tip : the stria: are very faint, and are finely
punctured.

The thorax of the male is more gradually narrowed anteriorly, and the antennse
extend to the posterior fourth of the thorax, while in the female they reach only
to the middle : in both sexes the third joint, though as long, is not as wide as
the fourth.

Chalcolepidius smaragdinus, elongatus niger nitidus, dense subtiliter
punctatus,undique squamulis la?te viridi-aureis dense tectus, antennis pedibusque
cyaneis, illis articulis 2 et 3 minutis, thorace latitudine sesqui longiore lateribus
antice late rotundatis, scutello obovato, elytris striis fere obsoletis subtilius punc-
tatis. Long. -9 — 1-07.

San Diego trip. -Similar in form to C. viridipilis, but with the thorax much
less suddenly rounded towards the tip: the elytra are also very faintly striate,
and the striee not deeply punctured. The sc*ttellum is not emarginate at either
end.

As in C. viridipilis the antennae of the male are as long as the thorax, and almost
flabellate.

Pelecyphorns r i m a t u s, niger, thorace latitudine duplo breviore disco paulo
convexo subtilius disperse punctato, lateribus magis rotundatis confiuenter rugosis
late depressis, angulis posticis obtusis baud rotundatis, elytris ovatis, thorace vix
latioribus postice declivibus dorso subplanis grossius puuetatis subrugosis,
lateribus acute marginatis, epipleuris parce obsolete punctatis. Long. 1-0.

One specimen from Camp No. 7. This species is very different from any of the
other Asidites of our country, though it approaches the species indicated by me
under the name subcostatus (Proc. Acad. 6, 446) : the elytra are however
more densely and coarsely punctured, and without the three faint ribs seen in
that species. The antennas are shorter than the head and thorax, and moderately
thick, as in P. carinatus, sordidus, &c.

Pelecypborus d i f f o r m i s , niger, thorace latitudine paulo breviore, lateribus
late sensim reflexis, antice rotundatis medio angulatis, dein usque ad basin con-
cavis, basi truncato, angulis posticis fere rectis, disco parcius subtiliter, lateribus

postice acuminatis, minus profunde scabro-punctatis striis distinctis latis modice
profundis, humeris minutis porrectis, epipleuris subito reflexis. Long. .95.

Santa Cruz, two specimens: in one the thorax is slightly concave transversely,
while in the other the sides are considerably elevated. This species is closely
allied to P. elatus Lee. (Proc. Acad. G, 445) but is smaller and narrower, and
at once distinguished by the distinctly striate elytra: the stria? in the other species
mentioned, if present, are always very faint.

Euschide3 1 i r a t u s , latiusculus ater opacus, minus convexus, supra bre-nter
fiavo-pubescens, thorace latitudine sesqui breviore, antrorsum angustato, lateribus

extends to the tip of the elytia, the inner discoidal one ceases at one-third, and
the other two at one-fourth from the apex.

Durango, Chihuahua, Copper Mines, Los Organos, and at Camps 5, 6 and 7.
This species is of the form of E. obovata Lee. (Ann. Lye. 5, 127,) but is very
different by the convexity ot the thorax, which is only very finely margined : the
thorax varies inform, being sometimes nearly one half wider than its length, but
in general the two dimensions are equal. In the male the elytra are one half
wider than the thorax, in the female about twice as wide.

Epitragus submetallicus, piceus seneo-micans, fusco-pubescens, thorace

sinuata, angulis po3ticis rectis, dorso.parum convexo sat punctato, elytris thorace
duplo latioribus humeris oblique rotundatis, subtilius densius punctatis, punctisque
maioribus obsolete striatis. Long. -66.

San Diego trip, one specimen. Much larger than E. canaliculars, with the
sides of the thorax rounded in front and parallel behind the middle : the outer
striae of the elytra are almost entirely effaced, those near the suture may be dis-
tinguished by the rows of larger punctures. The head is coarsely and thickly
punctured, and inside of the superciliary ridge on each side is a moderately deep
jongitudinal frontal impression.

Los Organos, Camp 7, and San Diego trip. The variety figured by Erichson
has an unusual amount of red upon the elytra : that color generally forms an
irregular vitta, with diverging and anastomosing branches. It is closely allied
to C. vittatus Lee, but is larger, with the thorax more transverse, and the
elytra more unequal. The back part of the head is frequently of a dull san-
guineous color, and the same variation is also found in C. vittatus.

One male, San Diego trip. This very fine species belongs with L. longicollis and
sublineata, which it equals in size; the antenna? are of a brilliant black, the first
joint extends beyond the occiput, is slender at base, very much curved beyond
the middle, and much compressed and dilated, with a large shallow impretsion
on its anterior face near the apex ; the second joint is thick and obconical ; the
third is two-thirds smaller, and the fourth again larger, so that together they are
longer than the second ; the fifth and following are almost equal in length to the
third and fourth united, and are progressively narrower. The under surface of
the body is black, with all the sutures broadly pubescent with dense cinereous
hair ; the under surface of the femora is also similarly clothed.

which are moderately fine: the thorax is very faintly impressed each side ante-
riorly, and the sides are somewhat blackish in most specimens.

One specimen, San Diego trip. Allied in form and characters to A. t h o r a-
cica, and, as in that species, the first joint of the antennae is not longer than
the third.

One female, San Diego trip. The antennae are brown ; the sides of the occiput
converge, and the apex is very obtusely rounded and subtruncate.

Ophryastes val idus. niger (griseo-squamosns ?) breviter parce pubescens,

One specimen, Oct. 20th, (near Chihuahua.) Larger than 0. latirostri"s
Lee. (Proc. Acad. 6, 443) and sufficiently distinct from all the species known.

Ophryastes po r o su s, niger cinereo-squamosus, parce breviter pubescens,

From the same locality, one specimen. This also differs very materially from
all those heretofore known.

Caelocnemis punctatus niger, subnitidus capite thoraceque sat punctatis,

datis ad basin breviter sinuatis, angulis posticis rectis prominulis, elytris thorace
vix latioribus convexis seriatim punctatis, interstitiis subtiliter <*ugulosis sat
dense punctatis. Long. '83.

One specimen, from Lieut. Beckwith's Collection alontr lat. 38° ; probably
from Utah, as the genus has not heretofore occurred east of California. This
species is more elongated than usual, and differs from all the others known to
me by the thorax being less rounded on the sides and less narrowed behind, so
that it does not present the cordate form seen in C. dilaticollis, &c. The punctures
of the interstices of the elytra are very distinct, and although smaller than those
arranged in the rows, are so dense as to render the striae indistinct.

C. californica Mann, is unknown to me, and from the figure given (Mas.
Zool. 1844) approaches more nearly to this species in form ; the thorax, however,
appears to be more rounded and cordate. The elytra of that species are described
as having nine rows of punctures, while in C. dilaticollis Mann, only
eight rows are mentioned ; the fact is, that in all the species nine rows are seen,
but the marginal row in one description was omitted ; in cases when two species of
the same genus have a different number of striae on the elytra, the change is pro-
duced by some of the striae becoming obsolete, and the situation of the obsolete
striae can always be determined ; no phenomenon of the kind is to be expected
in this genus.

Bill without frontal knob, ander tail coverts dark chesnut, tail uniform me-
tallic green. Head and entire under parts very light cinereous with a pale pur-
plish or rosaceus tinge, especially on the head above. Upper parts dark cinere*
<>us with a green metallic lustre.

Nearly allied to C. cenea. One specimen in Coll. Acad, from Timor.

3. Carpophaga rtjfinuchalis, nobis.

No frontal knob, under tail coverts chesnut, tail uniform dark metallic green.

About the size of C. anea, and C. rosacea. Bill moderate, rather slender,
without frontal protuberance, wing moderate, second quill longest, legs mode-
rate or rather Jong, the upper half of the tarsus feathered, toes rather long, pad-
ded and flattened on their under surfaces, hind toe with a row of bristles on
t?ach side of the central row of scales, claws strong curved.

Neck behind with a wide transverse well defined band of glossy chesnut, suc-
ceeded by a narrow band of dark bluish cinereous. Head above light bluish
dnereoas. entire under parts light purplish cinereous (or vinaceous), nearh'
white on the throat and darker on the abdomen. Under coverts of the tail dark
rufous chesnut. Back, upper wing coverts, secondaries, rump, upper tail cov-
erts and tail above brilliant metallic green with golden and copper colored re-
jections. Primaries brownish black with a faint tinge of green. Inferior cov-
erts of the wings pale cinereous. Bill and feet light colored.

Dimensions. — Total length (of skin) about 14^ inches, wing 9, tail 5i inches,

Hab. — Unknown ; spec, in Mus. Acad. Philada.

Obs. — One specimen only of this bird is in the collection of the Academy,
and is from the Rivoli collection. It bears some resemblance to the species re-
garded by me a C. tenea, and in a measure resembles the figure given as the fe-
male of that bird in Knip and Prevosf's Pigeons, ii. pi. 4. It resembles also to
.some extent C. rosacea, (Temm). The large and well defined nuchal band dis-
tinguishes the present species from those mentioned and from all others that have
come under my notice.

4. Carpophaga Pickerihgii, nobis.

No frontal knob, under tail coverts light cinereons, tail above dark metallic
green. About the size of the preceding. Bill moderate, rather slender (with-
out frontal protuberance), wing moderate, second and third quills longest an<?
nearly eqwal, tail rather long, containing fourteen feathers, legs moderate, upper
half of the tarsus feathered, lower half presenting in front about three wide
transverse scales, claws strong, flattened laterally, curved.

Under coverts of the tail light cinereous. Entire head and neck and under
parts light purplish cinereous, darker and with the purple most distinct on the
top of the head, the breast and abdomen, the cinereous mingling gradually with
the darker color of the back, which with the rump, wings and tail are dark
ashy brown with a green metallic lustre most brilliant on the tail. Under wing
coverts light cinereous, under surface of the tail light glaucous cinereous. Bih5
(in dried skin) light ashy blue, feet light.

Dimensions.— Total length (of skin) about 152 inches, wing 9^, tail 9£ inches.

Hab.— Mangsi, Sooloo Islands, spec, in coll. Ex. Exp.

Obs. — This Pigeon belongs to the same group as C» cenea ; it differs in being
rather larger, in having the wings and tail longer, and in having the under tail
coverts light cinereous instead of dark chesnut. From C. lacervulata and C-
hadia it differs in having the tail uniform dark metallic green, with no terminal
bar as in those species. It also somewhat resembles C. cineracea? but differs in
having longer wings and in having the head above and neck behind light cine-
reous instead of dark cinereous.

The only specimens of this species that we have seen are in the fine ornithologi-
cal collection made by the U. S. Exploring Expedition, (Vincennes and Pea-
cock) now in the National Museum, Washington city.

1 dedicate this bird, as a slight testimony of respect, to Charles Pickering,
M. D., one of the Naturalists of the Exploring Expedition, who, in addition to the
materials for his valuable volumes, has, in his manuscript notes, now in my po-
session, made important contributions to Ornithology.

With a frontal knob, lower part of the abdomen, tibiae, ventral region and un-
der tail coverts bright rufous. Throat white, head above, neck and breast cine-
leous, darker on the former. Upper parts of the body, wings and tail dark me-
tallic green, under wing coverts dark brownish cinereous.

A distinct and well marked species. One spec, in Coll. Acad.

9. Carpophaga globicera, Forst. Desc. An. p. 166, (1844).

Male with a large frontal knob, under tail coverts chesnut, tail dark metallic
green. Head above and neck behind light ashy, nearly white at the base of the
bill. Entire under parts dark vinaceous, upper parts of the body, win«s and
tail dark metallic green, under wing coverts brownish black. Female without
frontal knob, and with all the colors paler.

Quite distinct from the preceding: ( C. oceanica), and from all other species
known to me. Well described by Forster as cited above. Of this remarkable
species two specimens are in the collection of the U. S. Exp. Exp., Vincennes
and Peacock.

10. Carpophaga latrans, Peale, Zool. U. S. Ex. Exp. Vincennes, Birds p.

206, (first edition, 1S48).

No frontal knob, under tail coverts tawny, tail above dark glossy liver brown.
Head, neck, and entire under parts dark vinaceous, more clearly ashy on the
neck behind, upper parts of the body and wings dark ashy brown, under wing
coverts and inner edges of quills bright rufous.

Of this fine species one specimen is in the collection of the Academy and is la-
belled as from New Guinea. Two specimens in the collection of the Ex. Exp.
are from the Feejee Islands. It apparently is allied to Columba Mayer i, Pre-
vost, (Pigeons iii. pi. 60).

No frontal knob, but with the membranes of the nostrils large, under tail
coverts light ashy, slightly tinged with rufous. With a frontal band of white
and a ring of white around the eye, head above and neck dark ashy brown, paler
on the neck in front, under parts ashy white. Upper parts of the body and
wings dark metallic green.

Two specimens in Coll. Acad, labelled in Europe as from the "Molucsas." It is
quite probable that this is the Colvmba myristicivora, Scopoli, and that the
large membrane of the nostril is intended to be represented in Sonnerat's plate.

12. Carpophaga AURORiE, Peale, Zool. LT. S. Ex. Exp., Vincennes, p. 201,

(first edition, 1848).

With a large frontal knob, under tail covprts dark plumbeous glossed with
metallic green, tail above uniform dark metallic blue. Head, neck and under
parts of the body light cinereous, nearly white on the former. Upper parts of
the body and wings dark metallic blue, changing to green in some lights, under
wing coverts dark lead color.

This handsome bird is allied to the preceding (C. perspicillata,) but is quite
distinct. Several specimens in the Coll. Ex. Exp. are from the Society Islands.

Columba pinon, Quoy andGaim. Voy. Uranie, Zool. i. p. 118, (1824).

No frontal knob, large bare space around the eye, abdomen and under tail
coverts maronne, tail ashy black with a white subterminal band. Head above,
back, rump and wings light cinereous, scapulars black. Neck before and behind
and breast light vmaceous. Bare space around the eye encircled with white.

One specimen in the Coll. Acad, without, label indicating locality.

14. Carpophaga Wilkesii, Peale, Zool. U. S. Ex. Exp., Vincennes, p. 203,

(first edition, 1848).

Columba Forsteri, Wagler, Isis, 1829, p. 739.

Bill with a frontal elevation, under tail coverts dark plumbeous, glossed with
metallic green, tail uniform dark metallic green changing to blue. Head, neck,
and entire under parts dark plumbeous, nearly black on the former, upper parts*
of the body and wings dark metallic green changing to blue in some lights, un-
der wing coverts dark metallic green.

We regard it as possible that this fine species may be the same as named by
Wagler as above and described by Forster in Des. An. as a variety of his C»
globice.ra. The under tail coverts are represented by both these authors as fer-
rugineous, which is not the case in the present bird, and there are other differ-
ences, especially the greater size of the species now before us.

Two specimens in the Coll. Ex. Exp. are from Tahiti.

15. Carpophaga lepida, nobis. Voy. Uranie, Atlas Zool. Ois. pi. 29 ?

Bill with a lariie frontal protuberance which includes the apertures of the
nostrils; wing moderate, second quill longest; tail rather short, composed of
twelve feathers, under tail coverts nearly as long as the tail. Legs short ; tar-
sus feathered for half its length, thick ; toes rather long, padded and flattened
on their under surfaces; claws strong, curved-
Frontal protuberances (at the base of the upper mandible) yellow. Entire
hea.d, neck, breast and abdomen light purplish cinereous, (or light vinaceous,)
changing to light cinereous on the back of the neck, where it joins the color of
:he back, and becoming darker and clearer vinaceous on the breast and abdo-
men. Back, upper wing coverts, secondary quills, rump and upper tail coverts
brilliant metallic green, with golden and copper colored reflections. Primary
quills and tail feathers brilliant metallic blue, the outer edges of the former and
both edges of the latter changing to green. Ventral region, under tail coverts

and tibiae reddish chestnut color: short feathers of the tarsi cinereous. Inferior
coverts of the wing light cinereous. Bill dark ; feet light?

Dimensions. — Total length (of skin) about 15^ inches ; wing 8£ ; tail 5 inches.

Hab.— Northern Australia? Specimen in Mus. Acad. Philada.

Obs. — The only specimen of this splendid bird that we have ever seen is that
above described, and which is one of the many highly valuable contributions to the
Museum of the Academy, made by Mr. Edward Wilson. It was obtained by
him in Europe, and bears a label only indicating the locality, as we have given
it above. It may be the species figured in Voy. Uranie, and regarded by Quoy
and Gaimard as Carpophaga cenea. ,

tail, beautiful metallic green, changing to golden and cupreous in some lights.
Under parts of the body and under tail and wing coverts white, the latter (under
wing coverts) tinged with ashy.

Numerous specimens of this magnificent Pigeon are in the Coll. Acad., from
various localities. I can detect no specific difference between those from
New Zealand and from elsewhere.

Head ashy white, paler on the throat ; under tail coverts chestnut. Entire
upper parts, neck before and breast, fine metallic green, changing to golden and
cupreous on the neck behind and back; abdomen white tinged with rufous ; tail

Of this splendid species I have doubts respecting the correct name, Columba
Forsterii having been previously applied to other birds of this famil)*. It is,
however, very probably Carpophaga poliocephala, as cited above.

There are in the collection of the Academy various other species that have
been included in the genus Carpophaga by authors, but the above are those only
of which I have seen specimens, and which appear properly to belong to it.

Colurnba gidaris, Quoy and Gaim. Voy. Astrolabe, Ois pi. 29, which is in the
Coll. Acad., is a JPtilinopus, Columba vitieksis, of the same authors, Voy.
Ast. Ois. pi. 28, of which the adult is in the Coll. Acad., (the young bird being
represented in the plate in Voy. Ast.) is more properly a true Columba.

In the above list I have stated the presence or absence of the frontal knob or
protuberance, which appears to be characteristic of some species, but not with-
out suspicion that its presence, or at least its size, may depend on season, and
may then be sexual only and confined to the male birds. It has to me much
the appearance of an appendage indicative of the season of courtship, and its true
value as a character is an interesting problem.

The species above alluded to, of which the specimens are in the collection of
the Exploring Expedition, will be figured in the Atlas to the volume on the
Quadrupeds and Birds of that Expedition, which I am preparing, and which will
be published during the ensuing year.

Ilerrerite, identical with Smithsontie.

By Dr. F. A. Genth.

When Herrera described an apple green mineral from Albarradon in Mexico-
having a distinct cleavage parallel with the planes of a rhombohedron, as a com-
bination of 55 58 p. c. of tellurium, 12.32 p. c. of sesquioxide of nickel and
31.86 op. of carbonic acid, all mineralogists, who were conversant with the
laws of chemical combination, considered it as nothing more than a mechanical
mixture, though the description appears to have been that of a simple substance.
Afterwards, Del Rio pronounced it " carbonate of zinc, with some nickel and
cobalt," and this being a very probable composition, which also answers ver}r
well to the physical properties, it was generally considered aSmithsonite, though,

1854.] 23S

(no other examination having been made of it.) as doubtful. I received, through the
kindness of Dr. J. L. Le Conte, a genuine and perfectly pure piece of the mineral,
which I have carefully examined. The physical properties of it agree very well
•with those given by Herrera ; with regard to its chemical composition, Herrera
has the merit of having correctly discovered in it the presence of carbonic acid ;
Del Rio, that of having found in it the oxide of zinc. With regard to the other
constituents, both were mistaken. A qualitative analysis has shown that this
mineral contains carbonic acid, oxide of zinc, oxide of copper, oxide of man-
ganese, magnesia and lime, but no traces of any other substance. The quanti-
tative analysis was made with the usual methods.

B. B. in a tube it blackens and does not give any " sublimate, which condenses
in transparent drops," (as Herrera stated,) but none at all. Upon charcoal in the
R. F. it blackens, and covers it with white incrustations, having a steel-blue
margin, which are yellow as long as hot ; and which, when moistened with
cobalt solution and re heated, become green. The mineral itself does not become
green, but brownish black ; and after having received a good reducing heat, it
shows under the magnifier, and when powdered in an agate mortnr, metallic
copper. With borax, it gives distinctly the copper reactions. Dissolves in acids
slowly, with effervescence. After weighing, I have carefully examined all the
separated substances for their purity, but neither traces of tellurium, nor those of
cobalt and nickel, could be detected.

0.6226 grs. of the mineral gave:

0.3783 grs. of oxide of zinc, or . . . 60.76 p. c. Zn 0 ;

0.0137 " " oxide of copper, or . . 2.20 " Cu O ;

0.0062 " " protosesquioxide of manganese, or 0.93 " Mn O ;

0.0025 " " pyrophosphate of magnesia, or 0.14 " Mg O ;

0.0092 « " carbonate of lime, or . . 0.83 « Ca O.

Herrerite is, therefore, nothing else but a cupreous Smithsonite, and its com-
position the following:

Carbonate of zinc,

On the occurrence of Gold near Reading. — In a paper upon the occurrence
of gold in Pennsylvania, read before the American Philosophical Society, and
published in vol. x. of their Transactions, 1 alluded to an auriferous quartz in
the neighborhood of Reading, Pa., and the examination of which afforded me
slight, through uncertain traces of gold. I stated at the close of the article, that " I
had no doubt that a more careful examination of the rocks in the vicinity, would
yield affirmative results in an examination for this metal." The views then expressed
have proved to be correct. Last summer, Mr. Philipps, a mining geologist, in
searching for iron ore on the farm of Mr. Entlicb, a few miles eastward from
Reading, and of Mr. Jonathan Deininger, about a mile from the same place on
the western slope of Penn's Mount, detected gold by washing specimens of the
ferruginous quartz. I called upon Mr. Deininger, who showed me the specimens
in his possession, and gave me some of the quartz rock from his farm. Mr. I ein-
inger showed me a specimen of gold, in weight I should judge between one and
five centigrammes, which was broken by himself out of the rock.

234 [December,

I have noticed tbis quarts scattered over the ground m various parts of
Berks county, some specimens bearing very strong gold characteristics; they are
partially water worn, but the angles are moderately sharp • on breaking them
open the enclosed masses of dark oxide of iron a?e apparent.

At the angle formed by the intersection of 8th and 9th streets, Reading, there
»3 a heap of stones gathered from the adjoining fields, containing about two per
cent, of pieces of this quartz rock ; I brought home specimens with me for ex-
amination. These specimens, together with those obtained from Mr. Deininger's
field by myself, were pulverized and washed, but without, in any instance, detect-
ing gold. They were then smelted with litharge and charcoal, and the button
of lead cupelled. Of course, the litharge was examined for gold. The 30 gramme
button of lead from about 100 of litharge gave a silver button of 0.00575 grms.,
and which contained no gold.

A. 8th street quartz — 65 grammes -f- 13-0 litharge -J- 10 black flux gave a lead
button of 14 grms., and silver 0.0075, which contained gold beyond a doubt, as
judged from its lustre and resistance to nitric acid,

B. Another portion of quartz from the same locality — 20t) grms 4- 400 lithrage
-f- 0.5 charcoal dust, gave lead IT grms. ; silver 0.008 7 5 containing gold,, though
not as distinctly as the last.

C> Quartz from Mr. Deininger's fields — 185 grms. + 370 litharge -j- 0.5 charcoal
gave 20 grms, of lead containing 0.00825 silver, in which no gold could be detected.

On the Incineration of Filters in Analysis. — In order to burn off the filters from
eertain precipitates i.i quantitative analysis, considerable pa-tienee is required
and loss of time involved,, owing to the presence of salts in the pores of
the filter. Fresenius, in his last edition of Quantitative Analysis, counsels patience
in such cases, and to facilitate the combustion by pressing tne filter against
the hot crucible by a platinum wire. I have found it advantageous, in such cases,
to use oxygen gas, as is done in some of the methods for preparing ashes of plants
for analysis. The results are good, and none of the contents of the crucible are
lost. The phosphate of magnesia-ammonia filter is thus burned off in quite a
short time, and without any loss of phosphoric acid. After the filter is car-
bonized, the lid is partially removed from the upright crucible, and a tube (plati-
num I use, but glass will do nearly as well,) with an orifice of one mm. in
diameter, delivers oxygen gas from a small vulcanized caoutchouc bag, so slowly
that it miugles with the air in the crucible and effects the combination quietly,
A crucible appears to be in the worst position possible for oxidation in the
manner in which it is situated in the flame, for the rising air currents are un-
favorable for combustion in the bottom of the crucible, and the air which does
enter is diluted with the products of combustion. Though this may be par-
tially improved by an inclined position of the crucible and lid, it is not obviated ,
and oxygen gas seems to afford a remedy with less risk than nitrate of ammonia.*
1 have not yet found any objection to its use from practice, and pure oxygen is
so readily obtained from the commercial chlorate of potassa by using the wash
bottles described in my article on " organic analysis by gas," and keeps so well
in vulcanized caoutchouc bags that I would recommend it to a trial.

Apparatus for the Analysis of Carbonates. — Both in Fresenius' late edition
of Analysis and in Rose's greater work are described apparatus for the de-
termination of carbonic acid by Fresenius' and Wills' process, using fine
balances. About a year and a half ago I described, in the Journal of the
Franklin Institute, a very convenient apparatus for this purpose, which
as it appears not to have come to the notice of chemists generally, and
as those of my chemical friends who have tried it have approved of it, I
will here shortly describe.

* Schultze (Fresenius' Anal.) proposes to burn filters and plant ashes by
creating an air current over the crucible by means of a broken retort neck,

The accompanying figure, which is of the natural size, will explain itself;
the part E B D is the drying apparatus, containing sulphuric acid and is of one
piece, the tube E being melted into the flask B. In making this part of the
apparatus I think it preferable to join E to A before blowing the bulb. The
apparatus which I made myself in this way, and with which I experimented, re-
mained sound, while of a dozen made by a professional gentleman, joining E
and B after the bulb was blown, six cracked at the joint. The carbonate
is placed in A with water, and C, with a wax stopper, contains hydrochloric
acid in case of insoluble sulphates, or is empty when the oil of vitriol of
B is employed to effect the decomposition. The tightness of the joints
is ascertained and the analysis carried on as in Fresenius and Wills' appa-
ratus. The lead glass apparatus which I constructed myself weighed, empty,
36 grammes, and when charged for analysis and with much sulphuric acid
weighed, together with the chloride of calcium tube-hook of Oertling's
balance which it fits, between 50 and 60 grammes. An apparatus of Ger-
man glass, made by a glass blower, weighed, with its cork and empty, 20 grms.
This apparatus unites lightness with great strength, which is at once
felt on handling the apparatus, which arises from the nature of the joint of
E with B, and from the construction of the decomposition flask A which allows
E to be made of a piece of stout tube. In its construction it is simpler than aay
that I have seen, not excepting Geissler's (Jour. f. pr., ch. LX., 35,) which has
one more joint, and that a ground glass one. A being entirely separate may be
washed and dried ready for a fresh analysis in a couple of minutes ; the sulphuric
acid in B will generally last for two analyses, and is ver}r easily emptied and re-
plenished. A small sucking tube with perforated cork fitting the capillary end
of the tube D, is used to bring acid on the carbonate, to draw air through at the
close of the analysis, and to fill and empty B with oil of vitriol. The joints are
the firmest possible in this apparatus, and the connections easily made, owing
to single tubes passing through the two cork3, which corks being very small
may readily be obtained of perfect quality. I have not found any error to arise
from the hygroscopic nature of the corks ; but if such be feared, it is easy to coat
their outsides with sealing wax varnish. The following are the experimental
results with the apparatus :

About one gramme of perfectly pure (tested) carbonate of soda yielded, in

236 [December,

«

two experiments, a per cen'age of carbonic acid 41.42 and 41.35, which differ
0.07 from each other, and the mean 41.38 differs 0.01 from the theoretical per
centage 41.37, sodium being taken at 23.178.

Carbonate of lime, (precipitated commercial,) which contained sulphate and
iron, gave the following results, the carbonic acid being evolved by nitric:

0.G3025 and 0.61625 grammes gave a per centage of carbonic acid = 41.65
and 41.70, difference 0.05. The theory for pure carbonate of lime requires
43.88.

In order to ascertain the error by evolving the carbonic acid from lime by
sulphuric acid, two more experiments gave 38.79 and 39.17 carbonic acid.

In order to ascertain whether the carbonic acid remaining in the flask A
could be expelled with a moderate boiling and thus obviate the necessity of the
air tube C, three analyses were made with pure carbonate of soda (the same
used as above) which gave the following results : 0.83, 0.859 and 1.0193
grammes gave a per centuge of carbonic acid 40.93, 40.34 and 40.49.

Rectification of Mr. T. A. Conrad's " Synopsis of the Family of Nuades of North
America" published in the "Proceedings of the Academy of Natural Sciences
of Philadelphia, February, 1853."

By Isaac Lea.

On my return home a few weeks since from a long absence in Europe, I found,
when looking over the Proceedings of the Academy, a new Synopsis of the
North American Naiades by Mr. Conrad.*

Finding in it numerous errors in regard to the dates of my memoirs and the
fynonomy of my species, I desire that the correction of part at least of these
errors may reach the scientific public by the same channel. I think it will be
difficult for anyone to understand how so many errors of dates, &c. could have been
written down. I had hoped that the day had gone by among us here, when any
other object than the true interests of science should have existed. It has been
very painful for me to be called upon, as I am, to defend my scientific labors
from an attempt to deprive me of much of that which I have won by pa-
tient labor and continued assiduity for so many years, and must protest against;
the recognition of the incorrect dates which I shall point out to the satisfaction,
T trust, of every man of science who takes any interest in the study of this
branch of Natural History.

I do not mean to correct the synonomy of this Synopsis, but I trust to satisfy
every one, that it can be of no value whatever where theda'es are so erroneously
stated. For myself, I shall rest until I have further light on the synonomy of
my Synopsis of this Family published in 1852, -which I believe will be found in
the main to be correct. It certainly was my intention to do justice to every
naturalist, and whenever I shall be shown not to have done so I will most will-
ingly make reparation.

Mr. Conrad commences his Synopsis by 6aying, " The present attempt to give
a synonomy of the North American Nuiades, has originated from the absence of
dates and references in Mr. Lea's memoirs. To render strict justice to every au-
thor according to date of publi< ation, is not only the duty of the naturalist, but
a necessity of science." (Vol. 6, page 243.)

If it were true that my memoirs were without " dates and references," and
the truism of the duty of naturalists to render justice was complied with by
the author, there would have been no occasion for me to trouble the Academy with
a rectification. He usually takes the date of the title of the Volume of the Trans-
actions of the American Philosophical Societv, where the species may have been
described, while the volumes published by the Society, as they are almost univer-
sally by all scientific bodies, were realty issued in parts at different times and gene-
rally in three parts. Thus when part first of any volume was issued, the Society
distributed copies immediately to their subscribers and to all the principal socie-

♦Vol. 6, p. 243, Feb. 8, 1853.

1854.] 237

ties in Europe and in this country ; and, when I have had in such part a memoir,
1 had two hundred and fifty copies printed for my own use, one hundred and
fifty of which I at once distributed at heme and abroad where I thought they
might be useful to science. When part second of the same volume may have
been printed, the same process took place, and when part third was ready, it took
the same course, with this addition, viz. a title page for the whole volume was
printed for the convenience of those who might choose to have their three parts
bound into a volume, and this title bore the date of the last part. Thus most
of these copies of my descriptions with figures, may have been in the hands of
the Zoologists of Europe and America for two or three years prior to the date
at which Mr. Conrad has stated them as being published. In addition, he usually
pays no regard to the dates of my descriptions printed in the Proceedings of the
American Philosophical Society or otherwise, prior to their subsequent issue in
the Transactions. Thus on the 18th August, 1843, I read a number of descrip-
tions before that Society and permission was granted to me to print them at
once. The following day, Aug. 19th, these descriptions were printed and circu-
lated. Now Mr. Conrad in his synopsis dates these as published in 1846 !*
three years aftar they were actually issued printed. The rule, however, which
the author says he will adopt of taking the date of the whole volume, when the
dafe of publication of each species cannot be otherwise obtained, is not always
followed, for the date in the title page of Vol. 3d is 1830, while the following
species described in this volume, U. occidens, U. rubiginosus, U. mulliradiaius, and U.
securis, he date3 in 1832, and U. helerodon,\ in the same memoir, he dates 1833; thus
species described and printed in (he same memoir, are by him often dated in different
years.

The question as to fixing with precision the date of discovery of a new form,
has been one of anxiety and doubt among men of science. For myself I have
never felt satisfied that it was judicious to make any change in the long received
rule of permanently fixing the date of publication! to be that, when the paper
was read before and deposited with the officers of a learned Society, with a view
to printing. Receiving as authority the dates issued by individuals in publica-
tions is exceedingly dangerous. There may be antedates, and these can rarely
be detected. In the case of a deposit of a paper with a learned society, in-
tended for publication, and a record being made of it at the time, there cannot
be any probability by collusion of the officers to make a change.

As much of Mr. Conrad's Synopsis involves the names and claims of Mr. Rafin-
esque, it becomes necessary to say something in explanation of my having in my
papers adopted but few of his names. It has been asserted that I wished to de-
prive this unfortunate naturalist of the credit of his labors. This I must deny.
I believe I was the very first writer who, coming into this field of inquiry, showed
a desire to do him justice. When I commenced, in 1827, the series of papers
which has grown since to many volumes, I did not find a single species credited
to Rafiuesque by Mr. Say or Mr. Barnes; but my friends, Dr. Griffith, Mr. Hyde,
Mr. Peale, Dr. Green and Mr. Stewart, all my predecessors, thought they could
recognise, probably, three or four of his species. In 1831. Professors Short and
ISaton, of Transylvania Medical College, Lexington, published in the Transylvania
Journal of Medicine a descriptive catalogue of the Naiades then known to themt
having collected quantities of them in Kentucky, Ohio, &c. As Mr. Rafiuesque
had been a professor in the same college, they very naturally desired to give him
all they could identify, and out of thirty-five species in their list, Mr. Rafinesque

* These are U. Buckleyi, U. Buddianus, U. minor, U. amygdalus, U. fuscatus

\ Publication does not necessarily mean printing and issuing a notice of a fact
or a discovery. Dr. Webster says, that publication is a "notification either by
words, writing, or printing," and Johnson defines it "the act of notifying to the
wor;d."

238 [December,

has but six given to him, viz: mytiloides, torulosus, metanever, torsus, iriqueler and
scalenius, the first, fourth and sixth of which Mr. Conrad now rejects.*

I went to the task of examination with the sincerest desire of making out as
many as possible of Rafinesque's species ; and having his original work before me,
went over it carefully four different times, but with nearly the same result as my
predecessors. I gave it up in despair, and lost my labor ; and I think I shall
show further on, that Mr. Conrad himself affords the test evidence of the utter
impossibility of satisfactorily fixing Mr. Rafinesque's species. It is now thirty-
four years since he published his memoirs, and for nineteen years Mr. Conrad
has had the advantage of having shells labelled by, he says, Mr. Rafinesque him-
self, f A single species, the TJnio triangularis Raf. of Mr. Conrad's Synopsis of 1834,
with its synonyms, will convince any unprejudiced person of the impossibility of
the attempt made to establish Mr. Ra6nesque's species. J

Dr. Griffith, Mr. Hyde and Mr. Peale have often told me that Mr. Say would
not listen for a moment to such an idea as giving any regard to his species, and
the works of Mr. Say fully justify this fact by the total absence of any re-
cognition of his authority for a single species, until some fourteen years after Mr.
Rafinesque's publication, he was induced to make his "Synonymy of the Western,
North American species of the genera Unio and Alasmodonta," recognising
many of the species of Rafinesque, and denying to me a single one.

The feeling of the western conchologists was almost universally against the at-
tempt to introduce Rafinesque's names, and most of those who had studied these
shells, and written on them, or were writing on the subject, addressed me on the
occasion, in utter despair of making them out.||

The principal conchologists of Ohio, in April, 1836, agreed to form " a list to
be adopted by western conchologists," and after consulting together on the sub-
ject, a manuscript list was sent to me by Judge Tappan, containing 112 species of
Uniones, three only of which are given to Rafinesque. In August following, they
more maturely considered the subject, and agreed to the nomenclature of a list
in which a single species only is credited to him, and this with a mark of doubt.
In a letter to me from Prof. Kirtland when he undertook the Zoological portion
of the Ohio State Survey, he says, "I am particularly pleased with your arrange-
ment of the Naiades \ It is altogether preferable to anything of the kind that
has ever come before the scientific public, and will bear the test of the closest
scrutiny and the severest criticism." * * * "I was unwilling to complete my
report on our conchology until I could avail myself of the information which it
contained. I shall adopt your names and arrangement with hardly an alteration."
When this important State Report came out in 1838, in the whole list of nearly one
hundred species of the family JYa'iades, there were but two accredited to Rafines-
que, viz : metanever and mytiloides, the latter of which Mr. Conrad does not admit
as a species in his Synopsis, but now declares it to be a synonym to clavus Lam.
Notwithstanding the decisions of the ablest of the western zoologists, there was
still an attempt to substitute by "guessing," the names of Rafinesque. This induced

*Mr. Poulson says in the preface of his translation, (Oct. 1831,) that but four
of Rafinesque's species were "known by his names, either in the works of Ameri-
can authors or in our collections."

fThis was done some twelve years after the descriptions were published, and
at a time when I believe no one in any branch of science considered him as re-
liable authority. He had been, according to Dr. Binney, in a "diseased state of
mind " for thirteen years. I believe no one pretends to say that the original
Specimens described by Rafinesque are in existence

JSee further on the numerous changes made by Mr. Conrad in the position of
this name and its abandonment at last.

Clark and some others. See Asa Gray's account of Rafinesque's Botanical Writ-
ings, (Sill. Journ., 1841,) where he says that " half his genera and species do not
exist at present," and that he described in "Natural History style, twelve new
species of thunder and lightning."

the members of the "Western Academy of Natural Sciences of Cincinnati," in
January, 1849, to review the subject, with an intention of settling this matter of
nomenclature. With that Society there could be no partialities, there could be
no reason for favoritism, any more than with the Reporter of the State, or the
other zoologists who had devoted so many years to the study of these interesting
molluscs. They went to the task with no other object than to " render strict
justice to every author." The result was published in a small work, "Catalogue
of the U?iios, Alasmodontas, and Anodontas of the Ohio river and its northern
tributaries, adopted by the Western Academy of Natural Sciences of Cincinnati,
January, 1849." There were admitted sixty-seven distinct species, of which three
'only are ascribed to Rafinesque, U.flavus, U.flexuosus and IT. nodulatus*

If I had been singular in my inability to make out Rafinesque's species and to
recognise him as authority, I should not, perhaps, have ventured alone, but the
exception is on the other side. If we turn to the admirable work of the late Dr.
Binney, on the " Terrestrial Molluscs of the United States," and there is not a more
able and judicious writer on the subject, we find that he wholly discards Mr. Raf-
inesque as being worthy of any regard. He says that the papers of Rafinesque
" are not deemed worthy of any consideration," (p. 36,) and further on he says
that" his diseased state of mind was observed about 1818" (p. 44); and again
at p. 48, he says, as the genera and species proposed by Rafinesque " are con-
sidered to be destitute of authority and entirely unworthy of notice, no mention
of them will be made in the text." He was in the habit of naming and describing
species which he never saw, as mentioned by Major LeConte, and a very remark-
able case of this kind exists in his publication of his genus Tremesia, in the same
paper with the Naiades. He described it as a trivalve fresh water shell living on
the rocks, near the mouth of the Ohio, like the Patellcs. He described the animal
and shell, and figured them (p. 54). But it is not pretended that he ever saw
either, and I doubt if there be one zoologist in the United States who believes in
the existence of the thing at all. In the American Monthly Magazine, Rafinesque,
in a previous notice, describes it under the information of Mr. Audubon. He does
not himself pretend to have seen it.

When I was in Paris, in 1832, Baron Ferussac told me that I was wrong in
admitting a single species of Rafinesque's if I had any doubt myself about them.
He was convinced himself that he could not identify with certainty a single spe-
cies. In the Magazine de Zoologie, p. 13, he says that u he had received from
him the same shells under different names, and others with the names evidently
not those which were given to them in his Monography. Therefore there results
inextricable difficulty for the determination of his species, to establish an exact
synonymy between him and others, who since have occupied themselves with
the mussels." It is true that the Baron subsequently made a catalogue in which
he gave precedence to many of Rafinesque's names; but it must be remembered,
that this was done under the impression that these were identified as the original
specimens described by him, and not, as now understood to be the case, new labels
to other specimens, some twelve or fourteen years afterwards. We have seen above
that Ferussac could make nothing of the labelled specimens sent to him by Ra-
finesque, " marked by his own hand," which marking Mr. Conrad assumes as
definite, while in reality I do not think them entitled to the least consideration.

*Stronger evidence could not be presented of the futility of the efforts made
by naturalists to give Rafinesque what they could by careful examination. The
earlier concholgists thought they could make out four of his species, torsus1 my-
iiloides, metanever and scalenius. Professors Short and Eaton gave him mytiloides
torulosas, metanever, torsus, triqueter and scalenius. Judge Tappan, with the best
disposition, gave him, metanever, verucosus and tuberadatus, but all with doubt.
In the list made by the western conchologists there is but one, IT. viridis, the de-
scription of which Judge Tappan says equally well applies to iris. In Dr. Kirt-
land's State Report, he accredits two to Rafinesque, metanever and mytiloides, and
the Western Academy of Natural Sciences give him only flavus, flexuosus and
nodulaius, not one of which is given to him by the other authorities above quoted.
Could anything, therefore, be more uncertain ?

240 [December,

Many years ago the distinguished zoologist, Mr. Swainson, sent to me from Lon-
don, for the purpose of identification, a numher of Uniones, which he had received
from Rafinesque, but of which he could make nothing. The confusion of pieces of
valves and names formed such a mass as utterly to defy any attempt at recogni-
tion of his species. I returned them, totally unable to identify them with any
satisfaction. Dr. Ward said that Rafinesque's descriptions and outline " would
equally well apply to six or eight different species." These facts fully account
for the difference of judgment between Mr. Say and Mr. Conrad in their Synopses,
both published in this city, dated April 1834. Even they with the 'specimens be-
fore them marked by Rafinesque himself, could not agree in very many cases.
Mr. Say considered that caslaneus, Lea, was lecvigatus, Raf., while Mr. Conrad
placed lens, Lea, as asjnonym to Icevigatus. Mr. Say makes zigzag, Lea, and do-
naciformis, Lea, synonyms to nervosus, Raf., while Mr. Conrad doubts that zigzag
is synonymous with nervosus, and makes do naciformis synonymous with truncatus,
Raf., which (donactformis) in his appendix, the next year, he considers a distinct
species, but which in the new synopsis of 1853 he placed with zigzag, as synony-
mous with nervosus, Raf.!

Without going further into long statements of discrepancies between Mr. Say
and Mr. Conrad in regard to establishing Rafinesque's species, it will be enough
to say that in the Synopsis of Mr. Say it will be found that out of sixty-one des-
criptions by Rafinesque he gives him thirty-eight species, and by comparing
these with the new Synopsis of Mr. Conrad, eighteen of them are more or less
different in their synonymy, or are entirely dismissed from the list of species.*

Not wishing to devote too much time or space to tracing out the changes of
of opinion by Mr. Conrad from time to time in attempting to substantiate Ra-
finesque's species, it will be sufficient to trace a single one through the various
sinuosities which he has carried it to this period. I do not know how many there
may be like it, but I think it ought to be sufficient to satisfy any one, that syno-
nyms based on such uncertain authority ought to be most carefully scrutinized.
The " synoptical table of the species of American Naiades with Synonyms,"
April 1834, was got up by Mr. Conrad with a view, he says, to u rectify the con-
fused nomenclature of American Naiades." How successfully this has been car-
ried out may be seen by tracing this only one which I have attempted to follow en-
tirely through with its connections. In the list of species (p 72) Mr. Conrad
sets down U. triangularis, Raf. as an established species, and adds as synonyms
lateralis Raf, sintoxia Raf., pachostea Raf., mytiloides Raf, ruber Raf. and pyrami-
datus Lea. Eighteen months afterwards, this u retification of confused nomen-
clature, was found to require itself a rectification, and we find in an appendix
dated Oct. 1835, under the caption of additions to and corrections of, the catalogue
of species of American Naiades," that ruber Raf. is not a synonym to triangularis,
but really a species, and that pyramidatus Lea, is a synonym to it ; also, that
pachostea Raf. was erroneously placed as a synonym to triangularis Raf., it too
oecoraes a type, and Cooperianus Lea, is assigned as a synonym to it. Mytiloides
likewise is no longer a synonym to triangularis, but it becomes one to clavus
Lam. The other three are as yet still considered synonyms to the type triangula-
ris might be better to cite a few of those to show at a glance, how much dis-
crepancy of opinion there is between Mr. Say and Mr. Conrad, and to show how
dangerous it is to science to admit such "guessing" where nothing should be
set down as certain that could not bear the test of scrutiny.

Mr. Conrad says it is incrassatus Lea.

ris Raf. But, in the following year, June 1836, in his " Monography of the Family
Unionida" p. 41, Mr. Conrad describes and figures mytiloides Rat. as a type, and
assigns to it as synonyms ruber Raf. pyramidatus Lea, and cardiacea " Say of
Guerin," and in his observations on this shell, now first considered by him to be
a species, he says, " this common species, since its first discovery in the Western
waters, has always been known by the name we have adopted"!* After these
three attempts one might reasonably conclude that the synonymy of triangularis
was perfectly settled to the satisfaction of the author of the Synopsis, but such
proved far from being the case. Seventeen years of further experience found Mr.
liafinesque's species " marked by his own hand," did not make his own species
right, and we have in Mr. Conrad's Synopsis of 1853, a remodelling of these names
of the most extraordinary kind. Triangularis which in 1834 was declared to be
a type with six synonyms is entirely dismissed, not recognized even as a synonym.
Lateralis, which then was pronounced to be a synonym to it, has also been dis-
missed. Pachostea, another of the synonyms, but which was in 1835 raised to
the rank of a type, is sunk into the same oblivion. Mytiloides which had been in
1836 raised to a species, from a synonym in 1834 to triangularis, and in 1835
changed to a synonym to clavus Lam., is continued a synonym to clavus, with
some entirely new companions, viz., scalenius Raf. cuneaius Raf. and modiolifor-
mis Say. We find sintozia which had remained for nineteen years, during all the
changes, a synonym to triangularis is now decided to be a species, and it assumes
that rank without any synonym. Ruber is once more considered to be a species.
It was in the Synopsis of 1834 pronounced to be a synonym to triangularis Raf.
In 1835 it was considered a species, and pyramidatus Lea assigned as a synonym
to it. In 1836 it was degraded to the rank of synonymy again, and had myti-
loides Raf. for its type. In 1853 we find it again promoted to the rank of a spe-
cies, with pyramidatus Lea, and coccineus Jay, as synonyms ! And will it be be-
lieved, after all these various attempts to "rectify" what was pronounced with
so much formality to be the object of the writer, and to "render strict justice to
every author," that he says, in a supplementary note, on this U. triangularis Raf.
in this Synopsis (p. 267) that " Mr. Poulson's cabinet contains no authentic speci-
men of this species, which is one I have never identified." What must we think
of such an admission? In 1834 he forms a Sjmopsis under the declaration that
he has at his command the specimens marked by Rafinesque himself. In this
Synopsis he declares triangularis Raf. to be a species with six synonyms. Through
the course of three years he separates from these synonyms three of them, which
he raises to the rank of species, and then at the end of nineteen years, he drops
the important type entirely, and candidly informs us in a note that it is a species
he "had never identified !" and in the same note he says that u pachostea, CUfford-
iania and lateralis are also uncertain species."

It will strengthen the evidence of the utter futility to attempt the establishment
of Rafinesque's species, by looking at Mr. Say's Synopsis, which had the same object
in view. He declares this U. triangularis Raf. to be a distinct species, and assigns
to it as a synonym U. ellipsis Lea.f and he pronounced my HI tides Raf. a species
which Mr. Conrad at the same time placed as a synonym to triangularis Raf.f

. _ _ __ — _ . 1 .

* Subsequently it will be seen that this species is degraded in the synopsis of
1853 again into the ranks of synonymy. 1 believe I was the first to give it a
place (1829) in the lists made to endeavor to throw light on the subject, and I
continued it in the various editions of my Synopsis in 1836, 1838 and. 1852, more
because a certain triangular shell was generally known to us under this name of
Rafinesque's, than that his description really fitted it.

f Mr. Say had previously, in his American Conchology 1831, considered U. ellip-
sis Lea, as being established, and he had figured and described it as mine.

X If it were necessary to have further evidence of the uncertainty of Rafin-
esque's species, we might trace another of these numerous discrepancies, taking
scalenius. Mr. Conrad in his Synopsis 1834 gives scalenius the rank of a species,
giving as synonyms cuneaius Raf. &ndpatulus Lea. In his appendix 1835 he makes
scalenius Raf. and modiobformis Say. synonyms to clavus Lam. In 1838, Mono-
graphy p. 92, he describes and figures patulus Lea., making it a distinct species,
and in his Synopsis 1853 he adds mytiloides to the synonym of clavus Lam., having
in 1836 considered mytiloides a distinct species, but he is still not sure tha.tcunea.tu4

242 [DECEMBER,

I shall be much surprised if the exposition of this species, triangularis Raf. will
not satisfy all unprejudiced zoologists of the hopelessness of these attempts to es-
tablish Rafinesque's species of the Naiades.

We come now to by far the most important part of Mr. Conrad's Synopsis — the
dates. He commences in the first line of his Synopsis, with the avowed purpose,
in forming it, to supply an assumed " absence of dates and references in Mr. Lea's
Memoirs," and he promises to "render strict justice" to every author according
to date of publication. Any one unacquainted with my memoirs, would suppose
from this that some at least were without dates ; such is not the fact ; every one of
tbem running through a course of twenty-five years is dated. The record of their
date is in the minute book of the American Philosophical Society and the record
of the day on which they were read and deposited with the Society, for publication,
is printed at the. caption of every one of the numerous memoirs, put there by the
officers of the Society. The day on which all these memoirs were issued printed,
is not easily ascertained, and this gives Mr. Conrad a field for assigning to them
erroneous dates, as we shall see in the sequel. It is a mere matter of figures, but
it will be seen that many are wrongly put down in his Synopsis. During the first
ten or twelve years that I was engaged in writing these memoirs, no one considered
there could exist any doubt, as to an author being entitled to his discovery ; if it
was communicated to a learned Society, and really was a discovery. It being is-
sued, printed, afterwards, was considered a diffusion of a knowledge of it. The
Society then printed no " Proceedings" to give immediate notice of such discoveries
abroad. It was not until in 1838 that the "Proceedings" were commenced. After
this period it was generally thought best to print in the "■ Proceedings" the sim-
ple descriptions of the species in a memoir, and the whole, in extenso, was sub-
sequently inserted in the Transactions.

Mr. Conrad has declared that he will not regard the date of the reading of any
such described species, and acting under this principle he cuts out a large num-
ber of my names, classifying them among the synonyms. But he is by no means
satisfied with this reduction. The date of a very large number is erroneous as
to the time of their being actually printed and circulated, as I have mentioned in
the first part of this paper, that is, by assuming the date of issuing the first part
of a volume to be that, when the last part was issued, while the first part may
have been circulated some years before.

In order to occupy as little space as possible, I will endeavor to tabulate these
errors. To take up my species in the order in which they occur in his Synopsis
and correct them, seriatim, would require great space. I commence with my first
memoir in 1827, and proceed chronologically to 1852.

Raf. is not distinct, as he says in a note that it may be a distinct species. Mr. Say
in his Synopsis makes scalenius Raf. and cunealus Raf. both distinct species.

*The four other species of this memoir are given by Mr. Conrad without any date.

fThis may be a typographical error and intended to be 1832, the same as lan-
ceolatus above it. Giving Mr. Conrad the benefit of this, it will still be found
that he has dated these two species fi ve years after they were read to the Society,
four years after they were printed and issued, and two years after the date of the
title page of the whole volume.

Printed descriptions is-
sued in the Proceed-
ings of that month, No.
33, p. 165, issued Aug.,
1845. Generally the
new species of this me-
moir are dated cor-
rectly (in 1845) by Mr.
Conrad. The tetra-
ffona is one year wrong,
and M. minor has no
date.

Tn my last Memoir read before and deposited with the American Philo-
sophical Society, March 5th, 1852, there are over fifty descriptions of new
species. Two of these Mr. Conrad has omitted, viz. : U. Oregonensis Lea,
and U. sticcissus Lea. Twelve he inserts without date ; the remainder are
dated correctly, — 1852.

This finishes the corrections of the numerous errors of date in Mr. Conrad's
Synopsis, as regards the long series of my memoirs in the Trans. Am. Phil.
Soc. It will be seen by the above tables of corrections, that he has, under his own
rule of the time of issuing them printed, erroneously dated about ninety of my
species. I do not pretend in this rectification to correct the synonomy of the

Anodonta tetragona Lea. Dated by Mr. Conrad, 1846

species ; at p. 250 it is made a synonym to glans Lea.

Synopsis, as I have stated before. It would require too much space and time.
Those interested in the subject must jud^e between the two synopses. I have
certainly seen nothing in Mr. Conrad's to induce me to change the synonomy of.
mine. I shall be at all times most willing to render my own more perfect by
corrections founded on fact.

Mr. Conrad gives precedence to claims on various principles. Sometimes he
gives the priority of manuscript names in letters or labels, to printed descrip-
tions and figures, as in the case of JJnio coccineus, which I described and figured
in the Trans. Am. Phil. Soc (Dec. 19, 1834). He inserts it in his Synopsis
" TJnio coccineus, Hildreth, MSS." Certainly I never intended to deprive my
old and excellent correspondent Dr. Hildreth of any credit due to his long and
ardent services in the development of the Natural History of the Valley of the
Ohio. He sent it to me with many others in June 1833. There were two shells
which he thought to be new, and the names he proposed were 77. coccineus and
Alasmodonta obscura. I had previously received the latter from him and named
it in honor of him (Unio Hildrethianus,) and communicated it to the American
Philosophical Society. I adopted his proposed name for the first, as I am always
accustomed to do, if it be appropriate, and called it coccineus. I also stated that
it was the name proposed in his letter to me. I put Hildrethianus among the
TJniones because it belonged to a peculiar group, by form and habit, which were
classed as TJniones. Mr. Conrad, while he gives the name of 77. coccineus to
Hildreth, objects to my retaining the name of plicatus as Lesueur's, instead of
giving it to Mr. Say as he does. It seems to me that the cases are entirely dif-
ferent. Mr. Lesueur gave the shell to Mr. Say with its name plicatus, as a new
species. Mr. Say considered it as only an undulated variety of his crassus,
pointing out that variation, and at same time said, that, " it is most probably a
distinct species, and if so, the designation proposed by its accomplished discove-
rer, '• plicata,' will be an excellent one." He did not describe it, and I believe
all the conchological writers of the time accredited it to Lesueur, viz. Barnes,
Rafinesque, Short and Eaton, Hildreth, &c. It was, subsequently to Mr. Say's no-
tice, described by Barnes in Silliman's Journal, and accredited to Lesueur — Say's
name following Lesueur's. It was then universally received as plicatus Lesueur,
and is still known as such. Although neither he nor Mr. Say described it, it is bet-
ter to retain its established authorship. If it be not retained as Lesueur's it
must be given to Barnes, who was really the first to publish a description of it.
The same want of stability of plan displays itself in the authorship of 77.
paliatus from South Carolina. Dr. Ravenel sent me this species labelled by
himself with this name. Believing that he meant to publish a description of it
himself, I quoted it in myjSynopsis, first edition, 1836, accrediting it to him, and
so continued it in the 2d and 3d editions. Mr. Conrad, on the contrary, accredits it
to me, and refers to the page of my Synopsis where I insert the species as Rave-
nel's, and he adds to this error by quoting for it the Trans. Am. Phil. Soc. vol.
x. page 79, pi. 7 fig. 20 where it will not be found, but quite a different species,
the TJ. poJlescens Lea, which, at p. 254 of the Proceedings, in his Synopsis, he
inserts as a distinct sppcies. I never described paliatus, nor claimed it in any
way. It never has been described, I believe, but having been so long known as
paliatus of Ravenel, 1 hope it will be continued as such. 1 have no desire to
have my name attached to any species which 1 have not been the fiist to de-
scribe.

Regarding the " notes " on several species at the end of Mr. Conrad's synop-
sis, having long since given my opinion respecting 77. complanatus, Solander, U.
obliquus Lam. and most of the others, I shall not repeat these opinions; but I
am glad to see in a note on cariosns, Say, (p. 264,) that he has at last done justice
to Lamarck in acknowledging his luteolus. In this note he says he followed
Ferussac in referring luteolus to that species, but that his "description does
not apply. It very well describes 77. siliquoideus Barnes." I stated in 1833
that, having examined Lamark's specimen of luteolus in Paris, I found it to be
a true siliquoideus Bar., and therefore have ever since given luteolus priority,
as I was bound to do in common justice. But notwithstanding that Lamark

248 [ [December,

'* very well describes the 77. siliquoideus Barnes,5' (under the name of luteolus}
as Mr. Conrad states, and that I had mentioned (Trans. 1833) having seen the spe-
cimen itself in Paris, still Mr. Conrad, in 1834, places luteolus Lam. as a sy-
nonym to cariosus, Say; and in 1836, changing siliquoideus Bar. into a type, he
says he would have adopted luteolus Lam., if Ferussac had not referred La-
mark's specimen of luteolus to cariosus, Say. Thus relying more on Ferussac 's
opinion (whom I found really not very well acquainted with our species) than
to his own judgment on studying a description, which did apply; or, on mine,
to confirm it, who had examined the original carefully. Now in 1853, he comes
to the conclusion that 77. luteolus Lam. = 77. siliquoideus Bar., exactly what I
stated twenty years ago in the Trans. Am. Phil. Soc. vol. 5, p. 91.

The note on 77. viridis Raf. (p. 266) may be answered by saying that in de-
scribing 77. Tappanianus, I did not then believe, nor do I now, that it is the shell
Rafinesque had before him when he wrote his description. He does not allude
to the striking peculiarity of the teeth of Tappanianus, and he says his shell is
« common in the Kentucky and the small rivers adjacent." The Tappanianus
is supposed not to exist in the west. The reason that I did not retain
the name of viridis and give it to Mr. Conrad as he suggests, was that I did not
believe that he and Rafinesque described the same shell, and I did not wish to use
the names of the latter.* The fact stated by Mr. Conrad, that the specimen was
labelled by Rafinesque himself as the 77. viridis, and that its habitat was the
Kentucky river, ought to have satisfied him that it was one of the nu-
merous errors of Rafinesque. f That there is an error in the habitat or the name,
there is no doubt. Mr. Say, in his Synopsis, with the advantage of comparing this
specimen labelled by Rafinesque, declares it to be his cariosus ! This affords
another of the very many difficulties attending the attempt to substantiate Mr.
Rafinesque's species. It has been the cause of the loss of an immense deal of
time among naturalists, and it would have been better for Natural History if he
was entirely "considered to be destitute of authority and entirely unworthy of
notice," as Dr. Binney years ago concluded.

As regards the note on obliquus Lam. (p. 265), Mr. Conrad suggests that I
considered undatus Bar. a synonym, because Mr. Barnes gave it with a mark of
doubt. Mr. Conrad does not advert to the fact that I had seen the original spe-
cimen in Paris in 1832, and that I had published my note of it on my return.

In his note on 77. fasciolus Raf. (p. 267) he says that the specimen was la-
belled by Rafinesque. Notwithstanding this it was not admitted by him in his
Synopsis of 1834 at all ! But Mr. Say introduced it in his Synopsis with multi-
radiatus Lea, as a synonym, which {multiradiatus) Mr. Conrad had admitted
as a. good species. In 1836, however, Mr. Conrad in his Monography, introduced
fasciolus Raf., and then degraded multiradiatus as its synonym. Now in 1853
he makes multiradiatus a synonym to ligarnentinus Lam., and fasciolus is made
to appropriate subangulatus Lea, as a synonym, which was described in Trans.
1840 in vol. 8th not 10th as quoted by Mr. Conrad.

I am gratified to see (p. 266) that 77. trigonus Lea, after twenty years denial,
is acknowledged to be a distinct species. In Mr. Conrad's Synopsis, 1834, he
made it a synonym to undatus Bar., as Mr. Say also did in his Synopsis. My
own label on the specimen given by me to the Academy at the time, was su-
perseded for years by Barnes's name of another shell. There never was any
doubt in my own mind about it, after I had given it a proper examination.

I object to Mr. Conrad's changing my name TJnio Moussonianus, named after
Prof. Mousson, to Moussianus, and that of Estabroolianus, named after Prof. Es-
tabrook, to Eastbrookianus , as well also Margaritana Vandenbusehiana, named
after Dr. Vandenbusch, to Buschiana.

* My having done so in the 77. interruptus and one or two others was entirely
an oversight and unintentional. I always intended to avoid using Rafinesque's
names.

f In a letter from the late Dr. Ward, of Chilicothe, 1836, he says in regard
to this species, " that is another of Professor Rafinesque's apocryphal tales."

1854.] 249

Some of my species seem to be entirely omitted in this Synopsis. I do not
observe U. aheneus, 77. occultus, IT. Oregonensis, 77. patulus, 77. pressus, 77. suc-
cissus, CT. multiplicatus (nor heros Say), Anodonta Dunlapiana nor An. glohosa.
In a note on cuneatus Raf. (p. 267), Mr. Conrad says it is a form between XT.
patulus and 77. clavus, but he does not place patulus Lea, in his list of species,
although in his Monography in 1838 he acknowledges it with a description and
figure.

At page 258 Mr. Conrad gives « 77. tenerus Ravenel, Lea, 1834, V. 63, 9, 2."
I never described nor figured this shell, and there is no reference to it in vol. 5,
Trans, at p. 63, nor is it figured in plate 9. 77. teneris Ravenel and 77. paliatus
Ravenel, are most singularly erroneous in their introduction. They have both
been well known under Dr. Ravenel's names by his kindly distributing them.
Having himself named them when he sent them to me, I distributed duplicates
at home and abroad with his names. Although he did not describe them subse-
quently, as 1 supposed he would, I still retained his names in my editions of
the Synopsis and quoted the authorship to him. Mr. Conrad, by not keeping
to a strict rule, gives in his Synopsis one (paliattis) to me and the other {tene-
rus') to Ravenel. To add to this error he refers to my memoirs for both of them,
quoting the page of text and the plates for figures, where they never have ap-
peared at all !

I trust that I have vindicated the dates of my species by references to the facts
regarding them. This defence has cost me much time in searching for the
proofs necessary to rebut the errors of this Synopsis, and 1 think it will not be
denied that it is effectually done.

The Report of the Treasurer for 1854 was read and referred to the
Auditors.

Dr. Leidy, on behalf of the Curators, read the following

REPORT OF THE CURATORS FOR 1854.

The alterations and enlargement of the building of th<? Academy commenced
in 1853, and found necessary to accommodate the increasing museum and library,
have so far advanced, that in a few more months they will be completed. In the
new museum room, arrangements of a portion of the cabinet are already begun,
but the Curators propose deferring, until the next annual report, a detailed account
of the improvements in the building and the re-arrangements of the museum and
library.

During the year just about closing, the donations to the museum have been as
follows :

Mammalia. — Of this class 57 specimens of 42 species hv.ve been presented.
Among them is a noble specimen of an Elk, Cervus Americanus, shot in this State,
and presented by a number of our members.

Birds. — A small but valuable collection of bird-skins from Honduras, was pre-
sented by Dr. S. Woodhouse. There were also 12 species of birds presented by
different members.

Reptiles. — A collection of 10 species from Central America, and 16 species
chiefly from Texas and New Mexico, was presented by Dr. Woodhouse ; a second
collection of 18 species from California, by Dr. Heermann ; a third collection of 9
species from the Gaboon country, Africa, by M. Belloni Duchaillu ; and a fourth
collection of 9 species from New Jersey, by Mr. S. Ashmead. Besides these,
various persons presented 16 species of reptiles.

Fishes. — Dr. Heermann presented a collection of 18 species from California, and
various members and others presented 12 species.

1854.] 253

Mollusks. — Dr. Albers, of Berlin, through Mr. Lea, presented a collection of
70 species of land shells, chiefly from Madeira ; Dr. Le Conte presented a valuable
collection of marine shells from the Sandwich Islands ; and Lieut. G. H. Hare
presented a collection of marine shells from the Mediterranean and other locali-
ities. Besides these collections, numerous specimens of 16 species were presented
by various persons.

Insects. — To this class we have obtained an unusually rich accession. John A.
Guex, E?q., has presented to the Academy his entire cabinet of entomology,
consisting of 1500 specimens of American and European Lepidoptera, and
nearly 17,000 species of Coleoptera, systematically arranged in accordance with
modern nomenclature, and nearly all catalogued. Other persons have presented
about 20 species of insects.

Crustaceans, arachnides, myriapods, annelides and zoophytes. — Of these classes of
animals, numerous specimens of twelve species have been presented by various
members.

Comparative Anatomy. — 2 skeletons, 5 crania, and 2 other anatomical specimens
were presented. One of the skeletons, that of a dog, was presented by Mr.
Lambert, the other, that of a Heterodon, was presented by Dr. Hallowell.

Botany. — A collection of plants from New Holland and the Azores was pre-
sented by Mr. R. Kilvington ; and a collection of 100 specimens from California,
by Mr. Henry Pratten, of New Harmony. Be ides these, 12 species of plants,
fruits, &c, were presented by different persons.

Palaeontology. — A collection of fossils from San Pedro, Santa Barbara, and the
Colorado Desert, was presented by Dr. Heermann ; a second from the south of
Europe, by Lieut. G. H. Hare; a third of cretaceous fossils from Dallas cc,
Texas, by Mr. A. Gouhenaut ; and a fourth of cretaceous fossils from Alabama,
and eocene fossils from Virginia, by Mr. Joseph Jones. Besides these collections,
fifty specimens of fossils were presented by different members and other persons.
Among the specimens are five of the tracks of the huge extinct Brontozoum
giganteum, in sandstone, from Connecticut, presented by Dr. T. D. Mutter, and
several fragments of Indian crania and teeth, encrusted with carbonate of lime,
from a cave in California, presented by Dr. W. H. Housten.

Vice-President Bridges in the Chair.

A letter was read from Mr. Joseph Harrison, Jr., dated Jan. 2, 1855,
accompanying the donation from him acknowledged this evening.

On leave granted, the Committee appointed at last meeting to prepare
a memorial to Congress soliciting aid to Dr. Kane and his companions
in their Arctic peril, reported the following memorial, which was
adopted.

To the Honorable the Senate and House of Representatives of the XJnited

States in Congress assembled.

The Memorial of the Academy of Natural Sciences of Philadelphia, respect-
fully represents :

That Dr. Kane, a member of the Academy, and his companions, may at this
moment be in urgent need of the protecting hand of those in whose power alone
it is possible to give material aid.

Knowing well the prudence and perseverance of Dr. Kane, it cannot be doubted
that he has taken all the precautions possible for the safety of those who have
been placed under his charge in the perilous and benevolent voyage which he has
undertaken for the relief of that intrepid traveller Sir John Franklin. But it is
now known that Sir John is removed beyond all human alleviation of calamity,
and Dr. Kane and his companions, your memorialists believe, now stand in need
of that alleviation and support which they so generously volunteered at the risk
of their lives, in toiling over dreary wastes, and in braving the rigors of a polar
winter, as well as the storms of an Arctic sea.

Your memorialists fear that the cause of the delay of the return of Dr. Kane
may arise from one of those acccidents so incident to Polar voyages, the crush-
ing and destruction of his vessel by the ice, in which case a relief expedition
can alone in all probability mitigate his destitution and distress, and save him.

Your memorialists respectfully, but earnestly solicit that the earliest possi-
ble succour may be afforded to Dr. Kane and his companions.

On motion, the Secretary was directed to prepare copies of the above,
to be signed by the officers of the Society and transmitted to Congress.

On motion of Dr. Rand, the thanks of the Academy were presented
to Mr. Joseph Harrison, Jr., of this city, for his valuable donation of
portraits of Sir Joseph Banks and Dr. Samuel L. Mitchell, received this
evening.

Descriptions of three new species of Unio.
By T. A. Conrad.

UNIO.

1. 77. Grandensis. — Suboval, ventricose posteriorly, disks somewhat flattened ;
umbo distant from anterior margin, and with minute radiating lines extending
to- the tips of the beaks ; no concentric undulations; within purple.

Locality. Rio Grande, Texas.

Allied to 77. cardium, Raf., but differs in the striated beak, purple interior, &c

2. 77. Tanmilapanns . — Oblong, somewhat compressed; substance of shell thick
anteriorly and over the umbo; disks flattened; ligament margin nearly parallel
with basal margin ; umbo decorticated ; within pure white.

Allied to 77. niger, Raf., but more regularly oblong and very white inside.
Locality. San Juan river, Taumilapas.

3. TJ. Pearlensis. — Suboval ; umbo ventricose ; sides contracted before the
umbonal slope, which is ridged or inflated ; two or three radiating folds poste-
riorly, most prominent over the umbo ; within whitish, with a purple margin.

Locality. Pearl river, Miss. Prof. Thomas.

Allied to 77. crasside?is, Lam., {trapezoides, Lea,) but proportionally much
shorter, more ventricose over the umbones, and less folded. This shell belongs
to my proposed genus Plectomerus, which, if without sufficient distinction in the
animal to constitute a genus, will form a convenient and very natural subgenus.

Observations on the Eocene deposit of Jackson, Mississippi, with descriptions oj
thirty-four new species of shells and corals.

By T. A. Conrad.

The following table will show the order of succession of Eocene groups ; but
is not pretended to be more than an exposition of my limited knowledge of them,
though they are doubtless presented in the true order of superposition. Further
research may develope intercalated groups. No. 6, is probably synchronous with
the Orbitulite limestone of St. Stephens, Alabama, as its two most prominent
fossils are very abundant in this stratum at Vicksburg. No. 5, is the lowest bed
exposed in the bank of the Mississippi river, at Vicksburg. Col. Wailes found
a large Ostrea on the top of the Jackson group, which is probably the shell
referred to in No. 5. It would be convenient to designate these sub-divisions
thus: — Claiborne group; Jackson group; Vicksburg group; St. Stephens group ;

Nos. 1 to 3 represent the Claiborne group; 4, Jackson group; 6, the St.
Stephens group ; 7 and 8, the Vicksburg group. When a group of corresponding
fossils is to be found elsewhere, its relative position can be stated by referring to
the typical subdivision which contains many identical species.

Since my discovery of the Eocene formation of Claiborne, Alabama, in 1832,
by means of fossil shells collected by Judge Tait, numerous localities have been
found in the southern States, and characteristic fossils have also been obtained
by Major Emory, in Western Texas, and even in California, by Mr. Blake.
Localities widely separated contain some species in common, but I did not anti-
cipate that groups would vary to the extent they do in the three localities of
Claiborne, Alabama, Jackson and Vicksburg, Mississippi. Col. B. L. C. Wailes,
of Mississippi, has lately discovered a new group of Eocene fossils at Jackson,
in which none of the Vicksburg species occur ; and of forty species, five only
are identical with Claiborne fossils. One of the Jackson shells, Cardium Nicolletti,
Conrad, was first discovered in the bank of Red river, Washita ; and, therefore^
this latter locality will probably prove to belong to the same division of the
Eocene as that of Jackson. The Mississippi deposit described by Col. Wailes,
is a group of shells chiefly, of more than ordinary beauty and preservation,
imbedded in sand of a gray color, consisting of fine angular grains of quartz and
minute fragments of shells. One of the species, Cyprcea fenestralis, is closely

258 [January,

related to C elegant, of Deshayes; two remarkable species which have no
analogue or kindred shell in later Tertiary formations. The state of preserva-
tion and the forms of these fossils are closely analogous to those of the Paris
basin"; and I find no recent nor any Miocene species among them. I believe the
group to be newer than the Claiborne deposit, and certainly older than that of
Vicksburg.

I think it will be found that No. 6, of the above table, represents that exten-
sive limestone, which, in Alabama, contains the Basilosaurus remains ; the
Laganum Rogersi, Morton, near Claiborne, and near Brandon, Mississippi, where
it has been discovered by Col. Wailes, occupying a higher position than the Jack-
son group. The limestone of Jacksonboro', Georgia, described by Lyell, is pro-
bably referable to the same division, and contains the Laganum Rogersi, (Scu-
tella Jonesi, Forbes.)

•

The following species of organic remains were collected by Col. B. L. C.
Wailes, and are figured in his work on the Geology of Mississippi. Those
illustrations are referred to in the descriptions.

CORBULA.

1. C. densata, Geol. of Miss. PI. xiv., fig. 9 — Triangular, subequilateral, very
thick in substance ; surface undulated and having angular concentric striae; um-
bonal slope submarginal and acutely carinated, posterior extremity angular.

Related to C. nasuta, Con. but proportionally shorter, thicker, with a more
rounded base, &c. The description applies to the larger valve, as I have not
seen the opposite one.

2. C. licarinata, PI. xiv., fig. 3.— Elevated, triangular, slightly oblique, thick
in substance, profoundly ventricose, with robust reflected concentric lines ; umbo
profoundly prominent, and the beak incurved; posterior slope biangulated ; space
between the angles flattened, direct.

Resembles C. o?iiscus, Con., but is thicker, more elevated, not rostrated, and
its slight obliquity is the reverse of that in the former species. I have not seen
the smaller valve.

LED A, Schum.

L. multilineata, PI. xiv., fig. 4.— Ovato-elliptical, inequilateral, ventricose,
with fine sharp concentric lines, which are somewhat undulated ; anterior side
rostrated, with closely-arranged, radiating, minute, tuberculated striae; posterior
side with unequal fine radiating lines, a few of which are very distinct; a few
radiating lines are continued near the base ever the middle of the valves.

Allied to N. ccelata, Con., but very distinct.

NAV1CULA, Blainville.

N. atpera, PI. xiv., fig. 5. — Trapezoidal, disk contracted behind the middle,
cancellated; concentric lines distant, imbricated ; radiating lines largest towards
the umbonal slope, subspinous ; umbonal slope acutely angulated ; posterior slope
excavated ; series of cardinal teeth uninterrupted ; inner margin crenulated.

CARDIUM, Lin.

C. (Protocardia) Nieolletti, PI. xiv., fig. 6. Proceed. Acad. Nat. Sc, 1841, p. 33.

This shell agrees, except in size, with the specimen originally described from
the Washita, and doubtless the beds of that locality will prove to be of synchron-
ous origin with those of Jackson. A species of Cardium very nearly allied to
this, 1 formerly believed to be the same; but it accompanies a different group,
and presents variations entitling it to be a specific distinction.

It is from Pamunkey river, Virg.

Compared with C. Nieolletti ; umbo less inflated, posterior margin oblique, shell
proportionally longer, and the radiating lines 22; in the other 25. The posterior
cardinal tooth larger, &c. It may be named C. lene.

1855.] 259

CRASSATELLA, Lam.

C. flezura, PI. xiv., fig. 7. — Trapezoidal, inequilateral ; ventricose medially ;
slightly contracted anteriorly, and more so posteriorly ; umbonal slope angulated
and prominent ; whole surface with concentric prominent lines, some of which
bifurcate anteriorly; inner margin crenulated.

Approaches C. protezta, Con., but has the strias over the whole disk, the car-
dinal teeth more compressed ; inner margin with larger crenulations, &c

GLOSSUS.

G. filosus, PI. xiv., fig. 8. — Orbicular, ventricose, with radiating lines, unequal,
medially flattened, and towards the ends angulated ; concentric lines microscopic,
series of cardinal teeth uninterrupted, generally large and prominent.

Allied to G. stamineus, Con., but very distinct.

OSTREA, Lin.

O. trigonalis, PI. xiv., fig. 10. — Triangular, fiat, sui face irregular, withsome
indistinct radiating lines; muscular impression obliquely suboval, situated nearer
the summit than the base; margin somewhat ascending, submargin carinaced.

A single imperfect upper valve is all that I have seen of this shell, but it is
widely different from any other Eocene species known to me.

PECTEN, Lin.

P. nuperus, PI. xiv., fig. 11. — Suborbicular, ventricose, with about twenty-
three angular, prominent ribs, crossed by fine closely-arranged wrinkled lines;
ears finely striated obliquely.

A single valve with the ears broken is all of this species in the collection.

UMBRELLA.

77. pla?iulata, PI. xiv, fig. 1. — Suboval, flattened, surface undulated, rising a
little towards the apex, which is prominent and acute, and situated much nearer
to one side and nearer to one end ; lines of growth conspicuous; inner side with
a very large suboval cicatrix, with radiating interrupted lines.

This fine species is the only one yet known in North America. Two speci-
mens occur, one of which is marked with some hair-like brown radiating lines,
both internally and externally.

CAPULUS, Mont.

C. Am-ericanus, PI. xv., fig. 1. — Obliquely ovate, longitudinally contracted on
one side ; lines of growth profound ; summit very oblique ; apex profoundly
prominent, acute, curving towards the base and projecting far beyond the basal
margin ; aperture obtusely oval or suborbicular.

TROCHITA, Schum.

T. alta, PI. xv., fig. 3. — Conic, elevated, with three or four transverse undu-
lations ; radii prominent, rounded, very irregular, interrupted, somewhat tuber-
culated; vertex central, spiral, somewhat prominent.

CLAVELLA, Swains. CLAV1L1THES, Swains.

1. C. humerosa, PI. xv., fig. 2. — Fusiform, volutions eight? rounded; body
whorl and penultimate entire, the others with broad rounded ribs; whorls cari-
nated below the suture and with revolving lines, most prominent towards the
apex; body whorl and penultimate, channelled above and contracted near the
summit ; body whorl angulated inferiorly ; beak long and straight.

2. C. varicosa, PI. xvi., fig. 7. — Fusiform, spire and beak elongated; whorls
nine, with distant, rounded, thick ribs and with revolving acute lines, which are
obsolete or less prominent on the ventricose portion of the body w horl ; papillated
apex formed of three volutions; columella nearly straight, and with microscopic

ongitudinal lines.
C. Mississippie?i$is, PI. xvii., fig. 8, is probably the same species.

260 [January,

MITRA, Eumph. Lam.
Subgemis Lapparia, Conrad.

Short-fusiform, spinous; apex papillary; beak very short, thick, twisted;
plaits as in Mitra.

M. (Lapparia,) dumosu, PI. xv., fig, 4. — Short-fusiform, volutions seven,
direct, obliquely flattened above, with a series of transversely compressed, distant
spines on the two largest whorls ; on the contiguous whorl they become nodules ;
two whorls below the apex papillary, smooth ; the next two longitudinally ribbed,
and the others longitudinally striated or with prominent lines of growth; whole
surface with revolving wrinkled lines ; plaits four ; beak profoundly ridged.

CONUS, Lin.

C. tortilis, PI. xv., fig. 5. — Ovato-turbinate ; spire obtusely conical with the
apex exserted, acute; whorls obliquely flattened, with revolving impressed lines
and transverse wrinkles, carinated near the base, direct between the carina and
suture; lines of growth on body whorl profoundly curved; base with a pro-
found thick fold.

Differs from C. sanrodens, Con., in having a more prominent and convex spire,
in the large twisted callus at base, &c.

ROSTELLARIA, Lam.

1. R, velata, Con., PI. xv. fig. 7. R. Lamarckii, Lea, Cont. fig. 164.

2. JR. slaminea, PI. xvi. fig. 9. — Fusiform, spire elongated, subulate abo^e ;
whorls fifteen; body whorl slightly concave with fine closely-arranged revolving
lines, and obsolete longitudinal undulations ; three upper whorls with curved
longitudinal acute ribs; the remainder covered with a polished calcareous de-
posit, and excavated at the suture ; body whorl angular on a line with the upper
margin of the aperture; labrum thin ; beak slightly curved.

This species occurs at Claiborne in great abundance.

VOLUTALITHES, Swains.

1. V. symmetrica ^YX. xv., fig. 8. — Subfusiform ; with longitudinal acute ribs
terminating above in short spines on the body whorl ; volutions excavated above,
where they are striated but not ribbed ; body whorl with raised alternated revolv-
ing distinct lines; above the angle they become almost microscopic; suture
margined below by a series of small points, and somewhat carinated ; plaits
three, slender.

Allied to V. Sayana, Con.

NATICA, Lam.

N. permunda, PI. xvi., fig. 2. — Suborbicular ; body whorl somewhat excavated
near the suture ; spire very short ; umbilicus very long, profound, with a central
broad rounded ridge, and the lower margin subcarinated ; columella subrectilinear.

APORRHAIS.

Subgenus Platyoptera, Conrad.

Shell with a profoundly expanded labrum which is entire, or without a rostrum,
and with the margin very thin and acute.

A. (P.) eztenta, PI. xvi., fig. 3. — Shell independent of labrum fusiform, with
prominent revolving rounded lines and intermediate fine lines, from one to three,
and longitudinal microscopic lines ; volutions rounded, covered towards the apex
with a polished calcareous deposit ; labrum within with impressed radiating
lines, becoming well marked furrows towards the base.

1855.] 261

MITRA.

Subgenus Fusimitka, Conrad.

Elongate-fusiform, smooth and polished with impressed revolving lines ; aper-
ture narrow ; plaits two prominent, and two obsolete, or much smaller than the
others; beak elongated.

To this subgenus belongs M. conquisita, Con., M. Mississippiensis, and
Con., of the Vicksburg deposit.

M. (Fusimitru) Mellivgtoni, PI. xvi. fig. 5. — Profoundly elongated, fusiform;
volutions ten, convex, six of which towards the apex have revolving impressed
lines, with the interstices transversely striated; in the contiguous whorl they are
distant and obsolete, except near the summit, where there are two distinct im-
pressed lines ; on the penultimate whorl one distinct impressed line, and the
summit of the body whorl obtusely carinated; spire longer than the aperture,
which is narrow ; plaits four, the two superior ones very prominent, robust.

Allied to M. conquisitas but much larger, proportionally longer, and with
the striae less deeply impressed. It may prove, however, to'be the same when
many specimens from the two localities can be compared. If it should be iden-
tical with the former it is the only species common to the Vicksburg and Jackson
deposits out of 40 species of the latter and 100 of the former deposit.

CARICELLA, Con.

1. C subangulata, PI. xv. fig. 8. — Turbinate; labrum expanded ; shoulder
subangulated ; body whorl flattened above ; spire short, conical, consisting of
4£ volutions, with microscopic revolving lines near the apex ; columella with
four remote plaits, the two inferior ones most oblique.

2. C.polita, PI. xvi. fig. 4. — Fusiform; smooth and polished, with revolving
lines inferiorly, and on two volutions of the spire ; the whorl above is papillary
and smooth ; columella with closely arranged microscopic longitudinal lines ;
plaits four, slender, prominent, remote ; beak slightly curved.

Allied to C. but proportionally shorter and very distinct.

SCALARIA, Lam.

S. nassula, Con., PI. xvi. fig. 6. — Foss. Shells of Tert. Form.
This shell, though much larger than the Claiborne specimens, specifically agrees
with them. Probably Lea's S. plamdata is the same species.

ARCHITECTONICA, Bolton. SOLARIUM, Lam.

1. A. acuta, PL xvii. fig. 1. — Much depressed, very thin and acutely cari-
nated on the margin; convex above, lower half of the whorls somewhat exca-
vated ; revolving striae linear, crenulated, with a minute intermediate crenulated
line, and a still finer line or two in some of the interstices ; base convex, flattened
and somewhat excavated towards the periphery, revolving striae linear, alternated
with a medial smaller line and two minute ones, nearly smooth, except four
from the umbilical margin, which rapidly increase in size towards the inner
margin; the marginal line profoundly crenulated ; a carinated beaded line on the
middle of each whorl within the umbilicus, which is profoundly scalariform.

2. A. bellastriata, PI. xvii. fig. 2. — Discoida], with radiating impressed lines,
which frequently bifurcate and are most profound at the suture ; whorls of the
spire carinated below near the suture ; periphery acutely carinated, margined
above by two approximate raised lines, and below by a prominent line which is
slightly marked by a microscopic impressed line ; base with three impressed
lines, that nearest the umbilicus profound; radiating striae interrupted by the
revolving lines ; base convex towards the periphery and concave towards the
umbilicus.

262 [January,

GASTRIDIUM, Sow.

G. vet/estum, Con., PI. xvii. fig 4. Proceed. Acad. Nat. Sc, vol. 6, p. 321.

The Jackson specimens of this species, being more perfect than those of
Claiborne, Alabama, exhibit six or seven denticulations below the tooth on the
labrum, which denticle is very short ; the base of the shell is carinated, and an
acute carinated line runs within the umbilicus near the outer margin.

CYPR^A, Lin.

1. C.pinguis, PI. xvii., fig. 3. — Obtusely ovate, rounded at base, but ob-
liquely flattened towards the aperture which is very narrow and denticulato-
striate on both sides; columella deeply indented near the base, and a dentate line
on the margin ; labrum excavated towards the base.

Allied to C. spkcsroides. Con., of Vicksburg, but much less ventricose and
very distinct.

Subgenus Cypr^edia, Swains.

2. C.fenestralis, PI. xvii., fig. 5.— Ovate, ventricose, decussated with acute,
prominent, distant lines, the transverse ones alternated in size; interstices with
microscopic lines parallel to the transverse ones ; aperture narrow, much curved
above ; columella with four or five plaits.

This beautiful species is nearly allied to C. elegans, Desh.,but is much broader,
and has microscopic regular lines which are not mentioned in the description of
the former, and it is probably destitute of them. The plaits on the columella of
the Jackson shell are much larger than in its European relative. These two
shells are so different from any in the more recent formations that they appear
to be entitled to a generic distinction, and they are peculiar to the Eocene period.

PHORUS, Mont.

P. reclusug, PI. xvii., fig. 6. — Trochiform ; whorls seven, obliquely flattened
on the sides; base flattened, slightly excavated near the periphery, striated ;
lines profoundly curved, wrinkled, acute, many of them minutely beaded ; base
partially covered with a polished calcareous deposit.

GALEODIA, Link. CASSIDAR1A, Lam.

G. Peterso7ii, PI. xvii., fig. 9. — Obtusely ovate, spire short, scalariform ; body
whorl with three distant revolving lines much larger than the others, which are
alternated, suture margined by a prominent acute line; inferiorly three revolving
lines larger than the others ; lower whorl of the spire carinated in the middle ;
longitudinal wrinkled lines veiy fine: labrum margin thickened, somewhat re-
flected ; inner margin denticulato-striate, with a prominent tooth near the upper
extremity; labrum reflected ; columella striated, inferiorly tuberculato-striate.

Approaches G. funiculosa {cassidaria) Desh., but very distinct.

PAPlLLINA,Con.

Pyriform ; shoulder angular and spinous ; beak long, with an obtuse fold on
the columella ; three volutions from the apex forming a papillated summit.

P. Mlssisdppiensis, PI. xvii., fig. 10. — Fusiform, with a series of distant,
very prominent spines and longitudinal undulations ; revolving lines prominent,
alternated, wrinkled and undulated ; three volutions from the apex entire, and
forming the papillary top; fold on the columella obtuse ; beak slightly tortuous.

In the geology of Mississippi where the shell is figured, 1 have incorrrectly
referred it to the genus Clavelithes. To this genus Papillina belongs the Eocene
species, Fusics papillatu.s, Con., of Claiborne. I have never met with a species
of this genus in the Miocene or more recent formation. It is probably most
nearly related to Turbinella.

1855.]

263

TURRITELLA, Lam.

T. alveata, PI. xvii., fig. 7. — Elongated; whorls about nineteen; revolving
lines prominent, about six in number alternated with a minute line ; volutions
excavated at base and minutely striated.

Allied to T. obmta, Con., (T. litieata, Lea,) of Claiborne, but greatly more
elongated.

Polyparia.

ENDOPACHYS, Lonsdale.

1. E. expansum. — Cuneiform, dilated, much compressed on the sides ; middle
ventricose with two prominent ribs ; end margins straight, direct, obliquely trun-
cated inwards inferiorly; medial ridge tapering gradually to the base, which is
thickened in the middle; surface regularly and beautifully granulated.

Locality. Jackson, Miss. Claiborne, Alabama.

2. E. triangulares — Triangular; sides a little undulated on the margin and
tapering towards the middle of the base, which is thickened, truncated and
rounded, medial elevation very wide, rounded, with two prominent ribs ; sides
excavated and suddenly compressed near the margins, which are acutej granu-
lations in form of radiating stria?.

Locality. Occurs with the preceding.

The sides between the ribs and the depression are convex, and when perfect
have probably a rib on the middle.

3. E. alticost'itum. — Cuneiform, subtriangular ; medial elevation tapering
gradually to the base, which is thick and irregularly rounded; ribs two, pro-
foundly elevated, compressed; lateral depressions profound, margins acute, ob-
lique ; suiface densely and minutely granulated; base truncated or obtusely
rounded.

Locality. Claiborne, Alabama.

FLABELLUM, Les.

F. Wailesii. — Triangular or cuneiform, concentrically somewhat undulated;
periphery irregularly subcarinated, sides plano-convex, subcostate, with im-
pressed radiating lines, many of them bifurcated; lamellae unequal, three smaller
between each of the larger ones ; sides with longitudinal tuberculated stria?.

Locality. Jackson, Miss.

OSTEODES, Conrad.

Form of Turbinolia ; transversely oval; lamellae numerous, anastomosing or
branched; centre composed of small, angular cells; submargin with similar
but smaller cells ; cellular or bone-like structure characterising the sides beneath
the surface.

Very distinct from Turbinolia or Turbinolopsis. To this genus belong my
Turb. cyanthus, from near City Point, Virginia, in the older Eocene ; and T.
caulifera, newer Eocene, Vicksburg.

O. irroratus. — Conical, sometimes elongated, recurved, transversely oval ;
sides writh closely arranged, acute, prominent, densely-granulated striae; lamellae
numerous and finely granulated.

ELECTION.

Dr. William Hunt, of Philadelphia, was elected a Member of the
Academy.

February Qth.

Vice-President Bridges in the Chair.

The following paper, intended for publication in the Journal, was pre-
sented : — " Notice of Fossils from the Carboniferous Series of the Western
States, belonging to the genera Spirifer, Bellerophon, Pleurotomaria,
Macrocheilus, Natica and Loxomena, with descriptions of eight new
characteristic species : by Joseph G. Norwood and Henry Pratten, of
the Illinois Geological Survey. " Referred to Dr. Leidy, Mr. Isaac Lea,
and Dr. Wilson.

February \2>th.
Vice-President Bridges in the Chair.

A letter was read from Dr. Henry G. Dalton, dated Georgetown, De-
merara, British Guiana, Dec. 28th, 1854, transmitting a copy of his re-
cent work on that country.

Also, a letter from the Zoological Society of London, dated 81st
October, 1854, acknowledging the receipt of the Journal and Proceed-
ings of the Academy.

Mr. Conrad presented for publication in the Proceedings three papers
severally entitled " Descriptions of eighteen new Cretaceous and Ter-
tiary Fossils," " Descriptions of eight new species of Cretaceous Shells
from Texas, in the collection of Major Emory," and " Description of a
new species of Melania ;" which were referred to Mr. Cassin, Dr. Car-
son and Mr. Foulke.

1855.] 265

February 20th.
Vice President Bridges in the Chair.

A letter was read from Dr. George Dock, dated Harrisburgh, Penna.
accompanying the donation from him acknowledged this evening.

Dr. Le Conte presented a paper for publication in the Proceedings,
entitled " Synopsis of the Pyrochroides of the United States :" which
was referred to Mr. Guex, Dr. Zantzinger and Mr. Cooke.

Mr. Cassin presented a paper for publication in the Proceedings en-
titled u Notes on North American Falconidse, with descriptions of new
species." Referred to Dr. Wilson, Col. McCall and Dr. tlenderson.

Mr. Isaac Lea exhibited a specimen of the tanned skin of the Walrus.
It consists only of the cutis vera, and is one inch and three-sixteenths
in thickness. It was manufactured near Hull, and is used for polishing
cutlery.

Mr. Cassin remarked with reference to the specimen of Crex pra-
tensis presented this evening, that it was the first he had ever known to
be obtained on the continent of America, and the species is another to
be added to the list of accidental visitors from Northern Europe. Of
this description of stragglers, the European Widgeon and the European
green-winged Teal most frequently occur, but no specimen of a land
bird had ever come under bis observation, the present specimen being
the nearest approach to it. This specimen he had been assured by Mr.
Patterson, who presents it this evening, was shot in the vicinity of
Salem, N. J., and was prepared by him from the recently killed bird.

February 27th.

Baculites annulatus. — Subcylindrical, ribbed ; ribs annular, some of them
robust, flattened, remote, and generally partially sulcated or bifurcated, the
intermediate ribs narrower and less prominent; septa bifurcating in two long
equal branches, with intermediate comparatively short segments, the foliations
very acutely angulated.

side truncated; ribs obsolete on the back, prominent and acute laterally, and
increasing in elevation alternately towards the back, where they are truncated

263 [February,

and form two series of salient angles or tubercles; intermediate rib nearly
equal in size, rounded on the submargin of the back, entire. (A cast.)

C. (Ammonceras) Conradi, Morton. — This species was described from a
single specimen found at Walnford, Ocean Co., N. J. I have since obtained
another through the kindness of Miss Wain. It characterizes the lowest part
of the cretaceous series.

Descriptions of one Tertiary and eight New Cretaceous Fossils from Texas, in

the Collection of Major Emory*

By T. A. Conrad.
ROSTELLITES, Conrad.

Univalve, elongated, with an expanded labium, and having numerous oblique
plaits on the columella.

This genus is related to Apoorhais, but differs in having a plaited columella.
The entire shell or cast has never been obtained, and the outline cannot be
determined.

Rostellites Texanus. — Narrow, elongated, with a subulate spire; plaits
oblique, narrow, acute, largest above, and becoming obsolete towards the base;
whorls of the spire flattened on the sides.

Locality. — Eagle Pass.

The description was made from a cast, with only traces of the shell remaining,
the substance of which appears to have been thick, A large portion of the flat-
tened columella remains. The cast is associated with Cardium congest um.

TURRITELLA, Lam.

Turritella irrorata. — Slightly turrited, subulate, elongated ; whorls with four
to rive fine revolving unequal beaded lines on each, and an intermediate smooth
minute line.

Locality. — Between El Paso and Frontera ?

This shell differs from T. seriatim-granulata, Roemer, in having much finer
lines and tubercles, and in having a smooth line between each of the beaded
ones. It is associated with Nodosaria occidentalism the very small Venus quiit-
quecosta, and the little Corbula occidentalis. It is imbedded in a highly fossil-
iferous, ferruginous, indurated clay, which appears to have been obtained from
the same bed with Cardium Texamtm.

CAPRINA.

1. Caprina planata. — A fragment of one valve two feet or more in length,
and another smaller fragment represented in the figure. Flattened on one side
and convex on the other, a much compressed outline; the shell is very long and
narrow, falcate, fibrous, and distinctly exhibiting the small septa as they occur
in the genus Caprina. The cavities between the septa are lined with crystals
of carbonate of lime, and the shell is imbedded in white friable limestone
resembling chalk marl.

Locality. — Oak Creek, near Puercos.

2. C. occidentalis. — Falcate; flattened on the side of the outer curve, convex
on the opposite ; the other margins acutely rounded ; surface very obscurely
striated transversely; substance coarsely fibrous.

Locality. — Near the mouth of Puercos River, Texas. A. Schott.
The matrix of this shell resembles chalk marl.

1855.] 269

NEITHEA, Drouet.
/

Neithea occidentalism — Ovato-triangular, angulated; lower valve inflated,
unequally ribbed and concentrically lined, lines very fine; large ribs five,
rounded and elevated; smaller ribs equal, two in number in each of the intervals
between the larger ribs, which latter have on each side a raised line or fine rib,
giving it a trifid character; right valve flat, subconcave.

Pecten quadricostatus, var. Roemer. Kreid von Texas, p. 64, pi. 8, fig. 4.

This species differs from N. guadricostata in having but two equal ribs
between the larger ones, whilst that species has three corresponding ribs, and
it is also proportionally a narrower or more elevated shell. There is quite as
much difference between the two as between N. qnadricostata and N. quinque-
costata,.

MACTRA, Lin.

Mactra Texana. — Triangular, ventricose, subequilateral ; anterior extremity
subangulated and slightly produced, much above the line of the base, which is
regularly and profoundly curved; posterior margin obliquely truncated, ex-
tremity angulated ; anterior margin straight and very oblique ; umbo prominent.

Locality. — Prairie between Laredo and Rio Grande City, Texas.

This species occurs only in casts, and is placed with doubt among the cre-
taceous fossils.

EXOGYRA, Say.

1. E. fragosa. — Orbicular, lower valve ventricose posteriorly, flattened an-
teriorly ; ribs very large, prominent, irregular, some of them bifurcated ; umbo
not prominent, small, flattened, inner margin rugose-striate. Differs from E.
ponder osa, Roem., in its large ribs, small umbo, &c.

Locality. Between El Paso and Frontera. Major Emory.

2. E. fimhriata. — Upper valve. Very thick, profoundly convex, with ten or
twelve distant concentric imbricated lamina.

T Locality. Texas. Major Emory.

Tertiary Species.

O. contracta. — Subfalcate, elongated; cavity shallow and remarkably contracted
near the hinge. Length nearly two feet.

Locality. Oyster point, near Mier, Mexico.

Description of a Nevj Species of Melania.
By T. A. Conrad.

Melania exigua. — Turrited ; volutions 8, disposed to be angulated and some-
what scalariform above, cancellated, longitudinal lines wanting on the lower
half of the body whorl ; columella reflected ; aperture elliptical. Length one-
fifth of an inch.

Locality. — Colorado desert, California. Dr. Le Conte.

The specimens are numerous and of a chalky whiteness, showing that they
are all dead shells. Said to have been found one hundred and twenty miles
distant from any stream passed in the route. 1 am indebted to Dr. Caspar
Parkinson and Mr. Mactier for specimens.

Synopsis of the Pyrochroides of the United States.

By John L. Le Conte, M. D.

The definition under which I include the native genera helow mentioned,
some of which have been widely separated by preceeding authors, may be thus
expressed.

Coleoptera heteromera, capite postice coarctato, collo (Hstincto thoraci affixo;
oculis emar^inatis praecipue magnis ; abdomine articulis 5 vel 6 liberis, para-
pleuris parallelis; coxis anticis contiguis conicis, acetabulis postice imperfectis ;
tarsis articulo penultimo saepissime calceato vel emarginato, unguibus iam ad
basin dentatis, iam simplicibus, raro appendici basali elongata (sicut in Meloi-
dis pluribus) instructis.

Thus the group differs from Anthicidae by the emarginate eyes and paral-
lel parapleural ; while dentate or appendiculate ungues are not found in that
family.

In Lagriariae the anterior acetabula are closed posteriorly and the coxae are
small; the head too is hardly constricted.

Our genera may be thus arranged :

A. Collum crassum: tarsi articulo penultimo emarginato: ungues simplices :

abdomen 5-articulatum.
Palpi maxillares articulo ultimo dilatato, triangulari Eurygenius Ferte

Palpi maxillares articulo ultimo elongato, cultriformi Stereopalpus Ferte

B. Collum tenue, tarsi articulo penultimo lobato, abdomen 5-articulatum, ar-

ticulo lmo longiore: ungues dente magno armati.
Antennae articulis 3 ultimis maioribus, elongatis Macratria Newman

C. Collum tenue ; tarsi articulo penultimo praecipue lobato : abdomen articulo

Eurygenius Ferte.

1, E. Wildii, niger breviter nigro-hispidus, capite thoraceque densissime
pubescentibus, hoc canaliculato, campanulato, latitudine non longiore, elytris
pube sordida subvittatis. Long. *42.

Kentucky : a fine specimen of this species was recently given me by Mr. J. P.
Wild, of Baltimore, to whom I dedicate it with great pleasure, as a slight testi-
mony of my appreciation of his great energy and success in collecting similar
objects.

Larger than the following species. The head and thorax are very densely
clothed with brownish grey hair, with scattered suberect black hairs, and are
confluently punctured : the former is finely channelled between the eyes. The
thorax is subcordate, not longer than wide, canaliculate, much rounded on the
sides before ihe middle, with the anterior constriction distinct. The ehtra are
one half wider than the thorax, densely and coarsely punctured, with short black
hairs proceeding from each puncture; they are irregularly mottled with dense
brownish grey pubescence, with four narrow blackish vittae on each. Beneath
densely covered with grayish hair.

2. E. murinus, niger breviter nigro-hispidus, cinereo-pubescens, thorsice

subcampanulato, latitudine longiore, canaliculate, elytris guttis cinereo-pubes-
centibus variegatis. Long. -38.

Le Conte, Ann. Lye. of New York. 5, 152.

Ichthydion\ murinum Hald. Proc. Acad. Nat. Sc. 1, 304.

Georgia and Alabama, rare. Black, uniformily covered with ashy hair, and
with scattered short suberect bristles. Head and thorax confluently punctured,
channeled : the latter one third longer than wide, rounded on the sides before
the middle, very slightly narrowed behind; anterior constriction moderately
distinct ; elytra one half wider than the thorax, coarsely and densely punctured,
variegated with small spots of more dense ashy pubescence.

Although Prof. Haldeman's description is long anterior to the date at which
the present genus was established, he unfortunately did not give any generic
character, and I was therefore compelled to change the name given by him.

3. E. c o n s t r i c t u s , ater elongatus, cinereo-pubescens, longe griseo-his-
pidus, thorace campanulato, latitudine longiore, elytris guttis cinereo-pubes-
centibus variegatis. Long. «35 — «4.

Le Conte, Ann. Lye. of New York, 5, 151.

San Diego, California. Narrower than the preceding, covered both above
and beneath with ashy pubescence and long erect gray hairs : head and thorax
confiuenily punctured, not channeled : the latter is nearly one half longer than
wide, rounded on the sides anteriorly, a little narrowed behind, with the ante-
rior constriction very distinct. Elytra one half wirier than the thorax, densely
and coarsely punctured, variegated with spots of denser cinereous hair.

Michigan. Body dark brown, covered with fine cinereous pubescence : head
and thorax confluently punctured, black: the line between the eyes faint: thorax
scarcely wider than long, rounded on the sides anteriorly, then obliquely nar-
rowed to the base, slightly impressed each side at the middle : anterior constric-
tion short, distinct only at the sides : elytra wider than the thorax, coarsely
punctured, the punctures smaller towards the tip; light yellowish brown. Feet
reddish yellow : first joint of the antennae brown.

3. S. guttatus, aeneo-niger, cinereo pubescens, thorace campanulato, sub-
tiliter canaliculato, latitudine vix longiore, elytris guttis cinereis variegatis.
Long. #3.

Two specimens found at Fort Laramie, in Nebraska territory. Black, slightly
bronzed, finely pubescent : head and thorax confluently punctured, the latter not
longer than wide, rounded on the sides in front, then obliquely slightly narrowed
to the base, finely canaliculate, with a slight impression each side at the middle :
anterior constriction short, deep. Elytra densely and coarsely punctured, one
half wider than the thorax, variegated with numerous small round spots of
dense whitish hair.

Although colored like the species of the preceding genus, the palpi terminate
in a long cultiform joint.

obvious ; it has a meaning, and undoubtedly should not be altered so as to give
it a different meaning, either for the sake of uniformity of termination (!) or for
any other reason whatsoever, unless it can be shown to have been previously
occupied.

Middle and Southern States ; common. Body covered with very dense serice-
ous yellowish hair. Head finely punctured, slightly convex, narrowed behind the
eyes, and subtruncate : mouth and oral organs yellow. Antennae with the sec-
ond joint scarcely longer than the third : the following to the 8th are equal ; 9th
and 10th fuscous, pale at the tip, nearly as long as the two preceding united: thorax
very little wider than the head, one half longer than wide, elliptical, margined
posteriorly, finely scabrous. Elytra striate with fine punctures : interstices very
finely scabrous. Legs varying from yellow to piceous ; the anterior pair usually
paler. The male has the 5th segment of the abdomen truncate, whereby the
6th becomes visible. In the female the 2nd segment is impressed transversely
each side. In both sexes the first segment is conspicuously longer.

2. M. confusa, atra minus dense cinereo-pubescens, thorace elongato-ovato,
capite non latiore, elytris vix seriat impunctatis, antennarum articulis 3 ultimis
elongatis subaequalibus. Long. 18.

Two males. Georgia. Darker colored than the preceding, with less dense
pubescence. Head finely and sparsely punctured, rounded posteriorly, with the
occipital impression longer than in M. murina. Mouth and its organs yellow ;
antennee with the 2nd joint scarcely shorter than the 3rd, 3—7 equal, 8th fuscous,
a little shorter than the 7th ; 9 — 11 fuscous, nearly twice as long as the 7th and
Sth united, nearly equal, the 11th being a little longer. Thorax densely sca-
brous, not wider than the head, nearly twice as long as wide, disc subelliptical,
a little narrowed behind, where it is margined. Elytra with punctures arranged
in indistinct series, interstices scarcely scabrous or punctured. Feet piceous;
base of anterior thighs rufous. First segment of abdomen hardly elongated.

The discovery of this second species within our territory seems to confirm
the opinion of Ferte, that M. linearis Neivman, (Entom. Mag. 4, 377,) is dis-
tinct from M. murina, though the great carelessness with which Newman's de-
scriptions were made, should prevent us from placing reliance on them, in the
absence of any corroborating circumstances. Newman's figure does not show
the very strong basal margin of the thorax which exists in all the species of the
genus, and where a character so evident has been omitted, we are prepared to
expect any inaccuracy whatever, both in the outline and details of the figure.

In this genus the third joint of all the tarsi is lobed beneath, and the fourth
joint of the two anterior pairs is very small, and received upon the third. The
proper place is still not well determined: among the Anthicides it cannot remain
on account of the emarginate eyes.

York county, Pennsylvania ; Messrs. Melsheimer & Ziegler. Although by
the curious structure of the antennae of the male this beautiful species differs
from all the others below described, I can find no characters sufficient to cause
it to be separated as a genus. The feet vary in color, being sometimes yellow,
with only the posterior thighs fuscous: the antennas of the female are yellow;
the bands of the elytra are sometimes confluent, so that the elytra appear black
with yellow spots. The head is wider than the thorax, and the elytra are elon-
gate parallel, truncate at base, and nearly twice as wide as the thorax.

One specimen, Illinois, Mr. Willcox. The joints of the antennae from the 3d
to the 10th are nearly equal, and oblong in form : the 2d is a little shorter : the

what acute. The palpi are rufous.

The form of the antennae recalls Tanarthrus (Lee.) among the Anthicidae,
but the eyes are deeply emarginate, as in the other species of Xylophilus. The
legs are unfortunately all broken off.

Notes 071, North American Falconidce, with descriptions of new Species.

By John Cassin.

Since the time at which my Synopsis of the Falconida?, inhabiting America
north of Mexico, was published in the Proceedings of this Academy, (vi. p. 450.
December, 1853,) and since, too, the publication of a more extended Synopsis
in my Birds of California and Texas, several collections of high interest, contain-
ing numerous specimens of birds of this family have been made for account of
the Government, principally by parties that have been engaged in surveying
routes for a railroad to the Pacific Ocean. Various collections, containing birds
of this family have, also, since the periods alluded to, been received by this
Academy, in one of which from Greenland, there are specimens of Hierofalco of
apparently two species, being the only mature American birds of this genus that
I have ever seen.

In the present paper, t propose to notice additional localities of previously
known species, with such other information as may have been derived from the
collections alluded to, forming, in some measure, a continuation of my Synopses
above cited. For an opportunity to examine the collections belonging to the
Government, I am indebted to the officers of the Smithsonian Institution, in
whose custody they are, and more particular descriptions and all information
acquired will be published in the Reports of the officers who commanded the
various expeditions.

1. Falco nigriceps, Cassin, B. of Cal. and Texas, 1. p. 87, (Dec. 1853.)
The most mature specimen that has ever come under my notice, is in the

collection made by J. G. Cooper, M. D., one of the naturalists attached to the
Hon. I. I. Stevens' Surveying party. It is labelled as having been obtained at
Shoalwater Bay, Washington Territory, March 23d, 1854. The entire upper parts
of the body are light bluish cinereous, with which color the head above is more
decidedly tinged, than in the specimens originally described by me. The throat
and neck in front are white, very faintly tinged with yellowish; other under
parts white tinged with ashy and with transverse narrow bars of brownish black,
(every feather having about six bars.) Frontal band pure white; under wing
coverts pure white with brownish black transverse bars.

In this specimen, there is no trace of the pale yellowish red and circular black
spots of the under parts which have appeared in all other specimens that 1 have
seen.

2. Falco polyagrus, Cassin, B. of Cal., and Texas, 1 p. 88, (Dec. 1S53.)

pi. 16.

Adult specimens of this bird are in the collection made by Dr.Kennerly, who
was attached to the surveying party under command of Lieut. A. W. Whipple,
U. S. A., in New Mexico ; also in those made by Dr. Cooper, of Gov. Stevens'
party in Washington Territory, by Lieut. W. P. Trowbridge, U. S. A., in Cali-
fornia, and by T. C. Henry, M. D., U. S. A., in New Mexico.

The original descriptions are from female specimens. Those above alluded to
are all adults, and do not differ from my description and figure of the adult female
in any material point, except that a male in excellent plumage and condition

278 [February,

in Lieut. Whipple's collection is smaller. Its dimensions are as follows : — Total
length 16 inches, wing 12i, tail 7 inches. The young male of this species is in
Dr. Henry's collection, and differs from the adult only in being somewhat darker
in color, though not so dark as the young female described by me as above.

3. Htpotriorchjs femoralis, (Temm.)

A fine specimen and the first ever noticed within the limits of the United
States, is in the collection made by Dr. A. L. Heermann, who was attached to
the surveying parties in charge of Lieuts. Williamson and Parke, U. S. A. It
is an adult in fine plumage, and precisely identical with the South American bird.
Jt was obtained in New Mexico.*

4. Tinnunculus sparverius, (Linn.)

Numerous specimens from various localities demonstrate that this species
inhabits the whole of western (as well as eastern) North America. Specimens
from Tamaulipas, Mexico, are in Lieut. Couch's collection ; from San Francisco,
California, in Lieut. Trowbridge's; from Utah Tenitory, in Lieut. Beckwith's ;
and from Milk River, a tributary of the Upper Missouri, in the collection of Dr.
George Suckley, attached to the party in charge of the Hon. 1. I. Stevens.

brown. Plumage of the back, wing coverts and shorter quills with irregular
confluent transverse bands, and large snbterminal hastate or bluntly sagittate spots
of ashy brown* Primary quills white with their tips brownish black, and with
irregular and imperfect transverse bars of black, confluent on the shafts of the
feathers. Tail white, with transverse bars of brownish black in some of the
outer feathers, only observable on their outer webs.

Dimensions. — Total length (of skin,) about 24 inches, wing 16, tail 10 inches.

Young. Entire upper plumage with the brown predominating, and of a lighter
shade than in the adult, and tinged with ashy; every feather edged with white,
and more or less barred and spotted with white, and pale reddish. The brown
color showing a tendency to form the bands and sagittate spots of the adult.
Under parts white, tinged with ashy, with longitudinal stripes of brown, widest
on the abdomen. Quills ashy brown, with transverse bands of white tinged with
pale fulvous, tail ashy brown, palest on the middle feathers, every feather edged
externally with white, and with imperfect transverse bands (or pairs of large
spots, ) of white.

This fine species is nearly related to that next described, but can be distin-
guished by the different style of the brown marking of the upper parts. In the
present bird, the large subterminal sagittate or hastate spots are especially cha-
racteristic, and this character prevails also in the young bird.

The nomenclature of this and the succeeding species is difficult to determine
on account of their similarity.

* In Lieut. Couch's collection there are specimens of the following species
from Mexico.

1. Hypotriorchis columbarius, (Linn.) from the State of Tamaulipas.

2. Hypotriorchis rufigularis, (Daudin.) from the State of New Leon. This
species has not yet been detected within the limits of the United States ; but as
1he State of New Leon is only separated from Texas by the Rio Grande, it will
very probably be found in the State last mentioned.

Adult 5 • White, beneath with a few narrow longitudinal lines of dark brown,
most observable on the sides and flanks. Upper parts white, on the head and
neck behind with narrow longitudinal lines and stripes of dark brown. Plumage
of the back., upper wing coverts, and tertiaries white, with regular transverse
bands of ' broion,becomi ng somewhat crescent shaped on the scapulars and rnrnp, and
slightly acuminate on the shafts of the feathers. Primaries white, brownish-
black at their ends, and with imperfect, confluent, transverse bands of brown.
Tail white, with about twelve transverse bands of brown.

Young. Entire upper plumage brown, with transverse bands of dull white,
generally interrupted and imperfect in the middle of the feather. Under parts
dull white, with numerous circular and irregular-shaped spots of dark brown,
largest on the sides, and disposed to form transverse bands on the tibiae and
flanks. Quills dark brown, with transverse bands of white tinged with fulvous
on their inner webs; tail dark brown with transverse bands of ashy white.

Dimensions. — Total length (of skin) about 24 inches, wing I6£,tail 10 inches.

Specimens in the collection from Greenland are strictly identical with others
in the collection of the Academy which were presented by our distinguished
members, Messrs. Thomas B., and Edward Wilson, and carefully ascertainedto
be undoubted Iceland specimens by the latter gentleman.

In the present species the entire upper parts are transversely and nearly regu-
larly barred with brown, and the under parts less spotted than in the preceding.
The young bird also presents the same character on the upper parts in some de-
gree, while the under parts are spotted and transversely striped only, and not
with the numerous longitudinal stripes of the young of the preceding.

These two birds appear to be different species so far as I can judge from the
specimens before me, and are so regarded by nearly all modern authors. They
are, however, nearly related, and I am not without a suspicion of their identity.

11. Buteo borealis, (Gmelin).

In the comparison of numerous specimens of adults and young from various
localities in Western North America, with others obtained in the vicinity of
Philadelphia, I have failed to detect any differences not consistent with specific
identity. There is in some specimens a greater extent of the brown color on
the breast, and a deeper shade of rufous on the abdomen and tibiae, than is usual
in eastern specimens, but I have found no character in the western bird that I
have not seen at some time in the other. In my Synopsis I have erroneously re-
garded this bird as Buteo Swainsonii, which I have reason to suppose, as will
appear in my notice of that species in the present paper, has also been done by
other writers.

12. Buteo Bairdii, Hoy, Proc. Acad., Philada., vi. p. 452.

The only specimen yet obtained in Western America is in the collection made
by Mr. Kreutzfeldt, who was attached to the party in charge of Lieut. E. G.
Beckwith, U. S. Army. It is very similar to the specimen regarded as the more
adult of the two described as above cited, but has the brown spots on the under
parts larger, and the tibiae transversely barred with dark brown, and tinged

280 [February,

with rufous. It is labelled as having been obtained on the Rio Grande, in the
territory of Utah.

13. Buteo Swainsonii, Bonaparte.

In the collection made by Mr. Kreutzfeldt, of Lieut. Beckwith's party, there
are three specimens undoubtedly of this species, and the first that I have ever
seen.

This species is a typical Buteo, and though I cannot regard it as identical with
the European Buteo vulgaris, it is more nearly related to it than is any other
American species with which I am acquainted. Like that species, too, it pre-
sents a marked variation in the colors of different specimens, the present three
being all unlike each other in a considerable degree. One specimen is almost
exactly of the form, dimensions and colors as originally described and figured by
Mr. Swainson, in Fauna Boreali Americana, Birds p. 47, pi. 27, and stated by
him to have been made (both description and figure) from a male bird. On the
specimen described by Mr. Swainson, as a female, (in the work just mentioned,
p. 49,) I shall venture some observations below.

The first and apparently most mature specimen is as follows :

Bill wide at base, compressed towards the tip, edge of the upper mandible
lobed, cere large. Wing long, third quill longest, tail moderate, rather wide,
truncate, tarsus feathered in front for nearly half its length, naked behind, bare
portion presenting in front about twelve transverse scales, toes rather short,
claws strong. Entire upper parts dark brown, nearly black in the middle of
many feathers, and paler on their edges. Quills brownish black, with wide,
transverse bands of cinereous on their inner webs, becoming paler and nearly
pure white towards their bases. Tail brown* tinged with ashy, and having
transverse bands of a darker shade of brown, the subterminalof which is widest,
tip edged with white. Throat white, with longitudinal lines of dark brown,
neck before and breast ashy brown, some of the feathers edged with reddish. Other
under parts white, nearly pure on the under tail coverts, and strongly tinged,
and with transverse, irregular bars of rufous on the tibiae, abdomen with nume-
rous irregular and imperfect narrow Transverse bars of brown tinged with red-
dish. Under wing coverts white, with a few spots and transverse stripes of
brown. Bill dark slate color, tarsi and toes yellow.

Dimensions. — Total length (of skin,) 2H inches, wing 16, tail 5 h, tarsus 2£
inches.

The second specimen has the upper parts as just described, but darker.
Throat white, faintly tinged with yellowish, (without stripes of brown,) breast
dark brown, {nearly black), and the other under parts pale rufous, darker on the
tibiae, and with transverse stripes of brown on all the under parts less numer-
ous than on the abdomen of the preceding specimen, and more irregular. Total
length (of skin) 20£ inches, wing lSg, tail 81.

The third specimen has the upper parts about the same shade of brown as
the first described above, but with the tail darker, and the transverse bands
more indistinct. Throat white, with a few longitudinal lines of black, \eck be-
fore and breast light rufous, some of the feathers ashy brown in the middle,
other under parts white nearly pure and unspotted on the lower part of the ab-
domen and on the under tail coverts, tinged with very pale reddish on the tibiae,
upper portion of abdomen and flanks nearly pure white with a few spots and
transverse bars of fulvous and dark brown. Total length (of skin) 20 inches,
wing \b\, tail 8 inches.

In all these specimens the color of the neck before and of the breast, may
be said to form a wide uninterrupted transverse belt or band, and is a very con-
spicuous and apparently constant character. The sexes of these specimens are
not stated in the labels attached to them.

The tail in the specimens above varies merely in shade of the same brown
color. In the first and apparently the most mature specimen, it is strongly
tinged with cinereous. There is no tendency to become red in the tail of either
specimen.

281

Although I have no doubt whatever that this is the species indicated by the
description of Mr. Swainson as above cited, my opinion is that it is the male
bird only to which this conclusion applies.

The female described by Mr. Swainson does not appear to me to be of the
same species, but apparently is that of the Buteo borealis, in plumage not ma-
ture. A careful examination of the descriptions of the male and female here
alluded to, which are given by Mr. Swainson with his usual great accuracy, will
show some material points of difference. Of the male it is stated that " the
third quill feather is the longest, the fourth is nearly a quarter of an inch, and
the second an inch and a quarter shorter." Of the female <( the third an d fourth
quill feathers are of equal length." Of the male " cere and legs yellowish," —
of the female "the cere and legs have a bluish livid color." The last cha-
racter may, however, only indicate a young bird, and that the specimen was a
young bird, is further rendered probable by the statement that "the feathers
are more downy " than those of the male. The total length of the male is
given as 22 inches, that of the female 26 inches. All the measurements of the
female as given, and the description, apply to the immature Buteo borealis, es-
pecially to western specimens.

The bird figured by Mr. Audubon as Falco buteo (B. of Am. pi. 372) is the
young bird of Buteo borealls and not the present species. European naturalists
generally have regarded this bird as either identical with that species, or as
nearly related to it, both of which conclusions are erroneous.

14. Buteo calurus, nobis.

Form. — Similar in general form to Buteo azigur, tachardus and vulgaris. Bill
strong, edges of the upper mandible with distinct rounded lobes, wings long,
fifth quills slightly longest, tail moderate (or rather short). Tarsi feathered
in front for nearly half their length, naked behind, naked portion in front pre-
senting about ten transverse scales, claws large, strong, fully curved.

Dimensions (Of skin) sex unknown. Total length about 21 inches, wing

16£, tail 9 inches.

Colors. — Tail bright rufous above, white at the base, every feather having
about eight irregular and imperfect transverse narrow bands and one wide sub-
terminal band of brownish black, beneath silky reddish white. Entire plu-
mage of the head, neck and body above and below dark brown, nearly black
on the back and abdomen and palest on the breast. Plumage of the upper parts
with partially concealed transverse bands of white, and of the under parts with
circular spots and transverse bands of the same (also partially concealed).
Quills dark brown, with a large portion of their inner webs white, banded and
mottled with pale ashy brown. Tibial feathers and under tail coverts trans-
versely barred with dark brown and pale rufous.

Hob. — New Mexico, discovered by T. Charlton Henry, M. D„ United States
Army. This new and very remarkable bird presents a combination of charac-
ters quite unusual in an American species, and it bears a greater resemblance
to a Northern African species, Buteo augur, Riippell, than to any other with
which I am acquainted. In some degree it also resembles my Buteo insignatus
(B. of Cal. and Texas i. p. 102, pi. 31), but is much larger, and presents various
other strong points of difference. The present bird would present to a casual
observer the appearance of the Black Hawk {Archibuteo savcti-johannis) with
the tail attached of the common red-tailed Buzzard (Buteo borealis), a combina-
tion hitherto unknown amongst American Falconidae, but which exists in the
African Buteo augur.

The bird now described is in an extensive collection containing many inter-
esting and little known species, made by Dr. T. C. Henry of the United States
Army, whose exertions have continued unremitted for several years. It was
obtained in the vicinity of Fort Webster, New Mexico.

15. Buteo elegans, nobis.

Form. — Generally similar to Buteo lineatus. Bill rather slender, edges of

282 [February,

the upper mandible with a rounded not well defkied lobe, wing moderate, fourth
quill longest, first quill short, tail moderate, wide, rounded. Tarsus feathered
in front slightly below the joint with the tibia, naked behind, naked portion in
front presenting about twelve transverse scales.

Dimensions. — Total length, adult male ? (of skin) about 19 inches, wing 13,
tail 8 inches.

Colors. — Adult, generally resembling those of Buteo lineatus. Throat dark
brown with white longitudinal lines. Entire under parts bright rufous, darker
and unspotted on the breast, lighter on the abdomen, tibiae and under tail cov-
erts and with transverse bands of pale reddish white ; the latter (white) purer
at the bases of the feathers. Abdomen, tibia? and under tail coverts uniformly
colored.

Entire upper parts dark brown, feathers of the head and back edged with dark
rufous, upper coverts of the tail narrowly tipped with white. Shoulders dark
rufous, every feather with a narrow central stripe of dark brown, superior cov-
erts of the wings dark brown, edged on their inner webs with rufous and with
transverse stripes partially concealed, and circular spots of white, and tipped with
the same. Quills brownish black, primaries and secondaries with numerous
irregular transverse bands of white, running obliquely on their inner webs, all
the quills widely tipped with white. Tail brownish black, white at base, and
having four transverse bands of white and tipped with the same. Under wing
coverts rufous, barred with reddish white, uniform with the abdomen and under
tail coverts.

Dimensions. — Total length (of skin) male ? 19 inches, wing 13, tail 81 inches.

Young. Upper parts brown, plumage of the head edged with reddish white
and on the back with rufous, quills with their inner webs barred with white
and dark brown, the hands of the former (white) much the widest and narrowly
edged with rufous, all the quills narrowly tipped with white. Tail dark brown,
with four transverse bands of ashy white, purer on the inner webs and narrowly
tipped with white. Throat dark brown, with longitudinal narrow stripes of
white, other under parts dull yellowish white, every feather with wide trans-
verse and confluent bands of dark brown, and at its end a large arrow head of
the same color. These bands and sagittate spots giving the predominating color
(brown) to the breast and sides, but less numerous on the abdomen and under
tail coverts. Tibial feathers, inferior coverts of the wing and some feathers of
the shoulders pale rufous. Total length (of skin) 18 inches, wing 122, tail 8$
inches.

Ilab.— California, (Dr. Heermann;) New Mexico, (Dr. Kennerly.)

This bird, the adult and young of which are in a collection made by Dr. Heer-
mann, in California, and another )^oung specimen in Lieut. Whipple's collection,
bears a considerable resemblance to Buteo lineatus. The entire under parts are,
however, of a different red color, and continued to the abdomen and under tail
coverts. In the present species, this color is nearly a clear brick red; while in
B. lineatus, it is more of an orange color, and in the latter, the lower part of
the abdomen, and under coverts are nearly pure white in adult specimens. The
under parts in the young birds of the present species are entirely and strikingly
different from those of its relative mentioned.

16. Buteo oxypterus, nobis.

Form. — About the size of Btoteo pennsylv aniens. (Wilson). Bill rather long
and compressed, edge of the upper mandible slightly waved in its outline, but
scarcely lobed ; wing long, third quill distinctly longest, tail rather short, legs
rather long, tarsus feathered in front for about one third of its length, naked
behind, and with its naked portion in front, presenting about fourteen narrow
transverse scales, claws large, strong, fully curved.

Dimensioyis. — Total length (of skin,) sex unknown, about 16 inches, wing 131,
tail 7 inches.

Colors. — (Young bird, sex unknown.) Entire plumage above dark brown?
nearly black on the back. Feathers of the head white at base and edged later-
ally with the same; many feathers of the upper parts of the body also white at

1855.] 283

their bases, and with partially concealed transverse bands of white, quills very
dark brown (nearly black,) with the inner webs dark cinereous barred with
brown, tail above ashy brown, all the feathers white at base, and having; about
ten transverse bands of dark brown, outer feathers (of the tail) ashy white on
their inner webs, tail beneath silky ashy white, with a bronzed yellowish olive
lustre.

Behind and under the eye a stripe of rufous brown. Under parts pale yellow-
ish white, throat with lines and narrow stripes of brownish black, and on other
under parts every feather with a large lanceolate, circuiar or cordate spot of
dark brown, some feathers on the flanks and sides having also some irregular
transverse bands of the same color. Nearly all the feathers on the under parts
with lines of dark brown on their shafts.

Quills with their inner webs on the under surface of the wing grayish or dark
ashy, and near the shafts with a bronzed olive lustre ; shafts white (on the under
surface.) Inferior wing coverts white with arrow heads of dark brown. Tibial
feathers yellowish white, tinged with rufous, and having irregular transverse bars
of dark brown.

Adult, black?

Hab. — New Mexico. Discovered by T. Charlton Henry, M.D., U. S. Army.

The specimen now described is the young of a species the adult of which is as
yet unknown. It is about the size of B. pennsylvanlcux^ with the wings and
legs much longer and the bill also somewhat longer. The colors, too, are dif-
ferent, and in the present bird the dark cinereous of the inner webs of the quills
and the bronzed or silky olive lustre on their inferior surfaces are especially re-
markable. The exposed edges and ends of some of the secondaries in the pre-
sent specimen have a distinct purple lustre. I suspect that the adult of this
bird is black.

This bird is in the valuable collection made by T. C. Henry, M.D., U. S.
Army, and is from the vicinity of Fort Webster, New Mexico.

17. Archibuteo lagopus, (Gmelin.)

The Committee to which was referred a paper by Messrs. J. G. Nor-
wood and Henry Pratten, containing notices of Fossils trom the Carbon-
iferous series of the Western States, reported in favor of its publication
in the Journal.

The Committee to which was referred a communication entitled " Re-
marks on the Cryptogamic Flora of the State of Georgia, by Prof. Julien
Deby," reported in favor of publication in the Journal.

Dr. Leidy offered the following Preamble and Resolutions, which were
unanimously adopted. ■•

Whereas, Information has been received by this Academy, that a proposal
has been made to the Board of Regents of the Smithsonian Institution to change,
in several fundamental particulars, the system of administration adopted by said
Board ;

And whereas, The relationships of this Academy to the cultivation of the
natural sciences in the United States and elsewhere, give to it a peculiar interest
in the employment of the means best suited to the most liberal promotion of those
sciences ;

And whereas, Tt is the opinion of this Academy that, in view of the multi-
plied means which the zeal, enterprise and skill of the present.-age have furnished
and will continue to furnish, for the " increase and diffusion of knowledge among
men," it is eminently desirable that the special opportunities and aids rendered
practicable by the bequest of Mr. Smithsonp shall be discreetly applied to such
important objects as are not likely to receive assistance from ordinary sources ;

And whereas, Such application is to be guided rather by the relations which
the objects selected hold with important scientific generalizations, and with
the largest increments of scientific knowledge, than by considerations of mi-
nute or ephemeral utility ;

And whereas, The plan of operations adopted by the Board of Regents is
believed by this Academy to be well adapted to promoting, in the largest as
well as the most practical sense, "the increase and diffusion of knowledge among
men;" and that it possesses the advantage of supplying, according to a compre-
hensive and philosophic anticipation, the wants of the age, without superfluous
intervention in cases in which other agencies will surely produce the desired
results without such intervention ;

And whereas, The number, variety, and extent of the departments of know-
ledge, render it essential to the greatest usefulness of any plan of administration
of the Smithsonian fund, that it shall have the confidence of the persons upon
whose contributions its resources for good shall be mainly dependant ; and also
that it shall be maintained in operation consistently and without frequent change ;

Therefore, Resolved, That this Academy, as at present advised, would deeply
regret any material alteration of the plan adopted by the Board of Regents ;

Resolved, That, as an expression of the reasonable solicitude of this Academy,
and of the desire which its experience has occasioned for the continuance of
said plan, the President is hereby requested to forward a copy of the foregoing
preamble and resolutions to the Secretary of said Board.

Mr. Cassin presented a paper for publication in the Proceedings, from
Dr. T. Charlton Henry, U. S. A., entitled "Notes derived from obser-
vations made on the Birds of New Mexico, during the years 1853 and

Dr. Leidy read letters from Dr. Ruschenberger, dated Rio Janeiro,

and Valparaiso , transmitting donations of objects of

Natural History for the Museum, and giving some interesting information
relative to the state of Natural Science in Brazil.

Dr. Le Conte mentioned that a female cat in his possession having
been impregnated by a male of the tailless variety of cat, found in the
Isle of Man, had produced in her first litter two kittens, one of which
had a tail of half the usual length, while the other was entirely desti-
tute of all caudal appendage ; by a subsequent impregnation the same
female brought forth three kittens, two of which were similar in form to
the mother, while the third resembled the father in the absence of a tail.
Another young female, impregnated by the same male, brought forth
in her first litter four kittens, in all of which the tail was completely
absent. Dr. Le Conte proposed from time to time to furnish the Acade-
my with the history of the increase of this interesting family, as it fur-
nished a very convenient method of determining whether the physical
characters of the male or female are most frequently transmitted to the off-
spring. Dr. Le Conte mentioned also that the existence of this curious
ecaudate variety of the domestic cat had not been sufficiently noticed
by naturalists ; and that even its existence was alluded to in very fewr
of the works thus far published. A corresponding, or very nearly
similar variety was known in Japan, and, as already mentioned in the
letters from Dr. Ruschenberger read this evening, had been brought
thence by the Japan Expedition under Com. Perry, which had recently
returned.

Mr. Band remarked relative to the specimen of Uranite, presented this
evening, that although not remarkable as a specimen of this rare mineral,
it was interesting as being from a new locality which is now thought to
be exhausted. He believed that there are but three other localities of
this mineral known in the United States. The specimen is from the
western side of the Schuylkill near the Fairmount dam ; this locality
was discovered some two years ago by his brother Theodore D. H. Band,
who procured' quite a quantity of the mineral before the locality was
exhausted. After analysis, he sent a description of the locality to the
American Journal of Science and Arts. It was not noticed in that

1855.] 287

Journal, but in the last edition of Dana's Mineralogy the locality was
given, but without credit.

Mr. Isaac Lea read a letter from Dr. Deane, of Greenfield, Massachu-
setts, accompanying a photographic impression of some footprints in
sandstone, specimens of which he desires to dispose of.

Mr. Cassin read a letter from Capt. F. Bernsee, of the Ship Cou-
rier, wrecked on the S. W. point of East Falkland Island, in April,
1854, of which the following is an extract.

" The next morning when we found ourselves homeless and houseless, as well
as reduced to poverty, we commenced looking round for something to eat. In
this we had no trouble, for game and birds (of the kind I send you) weie more
abundant than I had ever seen them before ; and as few human beings had ever
trod that part of the Island, they were fearless and would come up to look at us ;
and we could get any quantity by knocking them down with sticks and stones.
The wolves, of which there were but few, would also come to look at us;
and would take a duck from one of our hands, while with the other we would
knock them on the head with a stick. I seldom saw more than one of them at a
time. Some wolves were caught alive by swinging a small line with a stone
tied to the end of it round and round the head with force, and when the wolf
would come for a duck or a goose which another man would shake at him, we
would let the stone with the line swing round his legs, and tangle him up so that
we could secure him. At one time we had six, ail caught in that manner, and
tied in different places around our tent, which we had fixed as a shelter from
wind, snow and rain, for winter was coming on. During the time we bad these
wolves prisoners, some fifteen or twenty would visit them at night, and make a
strange noise that would sometimes sound like the bark of a dog, and then
change to a snarl and a howl. They would get quite tame in two or three
days, but not sufficiently so to let them go loose ; they, however, would not bite
when we put our finders in their mouths, or threw them across our shoulders
and carried them like a dog. They appeared to be very playful, as those that
were not caught would come up in the daytime and have great times with our
dog ; but his courage generally failed him and he Avould run off and come up to
the men. They burrow in the sand hills : and I often found two or three open-
ings, which led through long channels underground to their kennel. They feed
chiefly on the large-sized geese sent you, as I have reason to believe from the
great number of wings, feet, and feathers I found. These wolves I found to be
very short-winded. They do not run even short distances with great speed; and
my sailors would often outrun them, when they would all at once turn short
round, and give up, blowing heavily with the tongue hanging far out of the
mouth, and then make the same noise as above stated. But they would never
make at us or show fight, but stand still and show their teeth.

288 [April,

"The large sized-goose is called by the inhabitants of the Island whom we
found six weeks afterwards, the upland goose ; the white one is the male ; these
birds are there in great numbers, but are seldom seen in large flocks ; I never saw
more than from twelve to twenty, but even in these flocks they will pair off and go
two by two at short distances from each other. They are oftener found in pairs en-
tirely separated from other geese. I found them away from salt water, and near
fresh water ponds. They live principally on a moss that grows there. In sum-
mer they lose all their feathers, and then as a matter of course cannot fly ; they
therefore keep constantly afloat in these ponds until their feathers grow out; I
watched these birds very closely during my stay. I found their habits very much
like other tame geese. Their meat is excellent eating, and not so dark as our
wild goose. In Patagonia and along the S. E. coast of Soutb America, th^y are
also found ; but there they are shy, and difficult to approach within gunshot.
Strange to say 1 have never met them on the west coast of South America in the
same latitude.

" The next goose in size is the Kelp goose. The black breasted one is the
female ; the pure w^hite, the male. These birds I never saw but in pairs, and
never away from the salt water. Their meat is hardly eatable. They are very
tame, and live principally among rocks and kelp. The young all look like the
female, but the young males afterwards change their feaihersand become white

" Of the small-sized goose, or the third kind, I shall make but few remarks,
as thfir habits are precisely like those of the upland goose. The inhabitants
call them the Poran goose. The male and female are alike. They are not
near so plenty as the upland goose. They, as well as the kelp goose, are found
around Cape Horn, and on the Island of Terra del Fuego.

" Another bird sent you, of a white color, is, both while flying and walking
on the rocks, so like the common domestic pigeon, that it is difficult to tell them
apart. Although not w7eb-footed, they fly at times great distances from the
shore; I never saw more than six or eight together, and generally single. They
feed on worms and insects which they pick from the cracks in the rocks, after
the tide has fallen. They are called Rock pigeons.

" Another bird, of which I saw plenty, a kind of Oyster-catcher, is black, with
a white breast, a long compressed bill, and long red legs. These birds gene-
rally go along the beach in pairs ; and give warning of danger by a long shrill
whistle.

" Another specimen is a bird precisely like the last in habits, but wholly
black. I did not find many of them on the Falkland Islands.

" I found a great many rats and mice on these Islands. Whether they are
different from our own or not I am unable to say ; their general habits are the
same. The mice, however, I think are smaller than ours ; and the legs of the
rats are of a red-flesh color, and almost hairless above the knee joint."

[Note. — The wolf, whose habits are well sketched in the above letter, is Canis
antarcticus, Shaw; the upland goose, Bernicla antarctica, Mellon ; the kelp goose,
Bernicla magellanica, Mellon ; the small-sized goose, Bernicla inornata, King;
rock pigeon, Chionis alba, Foi ster ; the oyster-catcher with white breast, Haema-
topus pailiatus, Terara.; the black oyster catcher, Haematopus ater, Vieill.J

Dr. Genth presented a paper for publication in the Proceedings, en-
titled, " Analysis of the Meteoric Iron, from Tucson, Province of So-
nora, Mexico." Referred to Dr. Le Conte, Dr. Bridges, and Dr. Wethe-
rill.

Dr. Le Conte desired to call the attention of the members of the
Academy to some very grievous misrepresentations contained in the
'Catalogue des Larves des Coleopteres', by MM. Chapuis and Candeze,
published in the eighth volume of the Memoirs of the Societe Hoyale
des Sciences de Liege. The portion he complained of was the article
-on the larva of Eurypalpus, (pp. 155-157), which purported to be, and

1855.] 289

was in reality, a literal translation of the account printed by him in the
work on Like Superior by Professor Agassiz, with the single exception,
that in every place where Dr. Le C<>ntu had taken occasion to mention
and criticise the erroneous views of Dr. De Kay regarding this curious
larva, the Belgian naturalists had substituted the name of Dr. Harris
for that of Dr. De Kay. This error was the more unaccountable, since in
Dr. Le Conte's original description, he had mentioned the name of Dr.
Harris but once, and then for the purpose of publicly expressing his ac-
knowledgements for some hints kindly given towards the true nature of
the larva in question, as well as for other valuable information, which
the well known accuracy of observation of Dr. Harris had enabled him
to give on various occasions, and which his liberal disposition prompts
him ahvays to offer for the use of his scientific colleagues. Dr.
LeConte concluded by expressing ardent wishes that foreign natu-
ralists, who seem but lately to have become familiar with works of science
published in America, would do our authors the justice, when they
quote, to quote correctly.

Mr. Cassin called attention to the specimens of Cards Antarcticus,
and of the several species of Geese and other Birds, from the Falkland
Islands, alluded to in the letter of Capt. Bernsee, read this evening.

On leave granted, Dr. Wistar offered a Resolution, which was unani-
mously adopted, inviting the members of the American Medical Asso-
ciation to visit the Museum of the Academy, during the session of that
body in this city, in May next.

The following species are not included in the above list, as I have not had
specimens for examination :

From Atlantic America; 81, H. aulicus Aube; 82, H. nigro-lineatus Steph.
(fide Kirby, Fauna Bor. Am. 66);

\ 1. Synonyms and Doubtful Species.

H. laevis Kirby, is possibly a variety of H. 12-lineatus Lee, and according to
Mr. White, (Cat. British Museum,) is H. alpinus Paykull.

H. ruficeps Aube seems not sufficiently distinct from H. modestus Aube.

H. limbalis Mels. is probably the female of No. 53, H. oblitus Aube, with which,
according to a typical specimen, H. luridipennis Mels. is identical.

H. discicollis Say, according to Dr. Harris, is H. dichrous Mels., but the des-
cription is very unsatisfactory, and I have been compelled to regard it as inde-
terminate.

H. interruptus and H. parallelus Say, are not different from H. catascopium.

H. hirtellus Lee, is smaller and more pubescent than H. subpubescens Lee.
but is probably only the female of that species.

H. fasciatus Harris (S. Engl. Farmer, ^ec, 1828) is H. undulatus Say ; the
male is H. pubipennis, and the female H. velutinus Aube ; for a typical specimen
I am indebted to Dr. Harris.

H. proximus Aube is probably H. oppositus Say, (vide infra No. 27.)

H. punctatissimus Aube is H. niger Say.

H. pulicarius Aube is H. lacustris Say.

H. nanus Aube is H. affinis Say ; for a type I return my thanks to Dr. Harris.

Hygrotus pustulatus Mels. is H. cuspidatus.

H. humeralis|| Lee. is now H. axillaris Zee.

E. luridipennis|| Le". Agassiz' Lake Superior, 216, is now H. lutulentus Lee.
(No. 501.) Farther investigation, aided by more extensive series of specimens,
may show the necessity of uniting with it H. tenebrosus, from which it differs
principally in color.

One specimen from Massachusetts was presented to me by Dr. C. Zimmermann.
A little less globose than H. cuspidatus, and readily distinguished by the
finer and denser punctuation, and by the epistoma being without a margin.

6. H. a car o ides, breviter ovalis, postice acutus, parum convexus, ferru-
gineus dense suhtilius punctatus, thorace margine basali nigricaate, elytris cos-
tula laterali parum elevata ad medium abbreviata, alteraque externa fere obsoleta;

Illinois., Mr. Willcox ; Kentucky, Mr. Wild. The elevated lines of the elytra are
very slight, but may be distinctly traced ; behind them, but apparently in con-
tinuation, is a linear brownish cloud which continues to the apex, outside of the
three discoidal spots, which surround the large subquadrate common spot at the
middle of the elytra. The spots are sometimes extended and become more or
less confluent. In H. latissimus the elevated line is very short, so that it appears
rather like a fold, limited externally by a moderately deep oblong fovea.

8. H. granum, breviter ovalis utrinque attenuatus, subconvexus, piceo-tes-
taceus nitidus glaber, capite subtiliter marginato, thorace parce punctulato,
lateribus rectis subtiliter marginatis, elytris subtiliter parce punctulatis. Long.
•05.

One specimen from Louisiana given me by Mr. Guex. Smaller and more con-
vex than H. convexus, which it very closely resembles ; the sides of the thorax
are, however, not broadly rounded as in that species, and the punctures of the
elytra are much smaller and more distant.

Desmopacbria ni ti d a Babington (Trans. Ent. Soc. Lond. 3, 17, tab. 1, fig. 5)
does not appear by its specific characters to be different from H. convexus Aube.
The generic characters agree accurately, except, that the posterior tarsi are not
four-jointed. This, if true, would be so anomalous, that the correctness of the
observer may well be doubted ; nevertheless, in H. convexus the posterior tarsi
are more flattened and more gradually attenuated than in the other species of
the genus, and therefore the terminal joints are more closely connected ; should
the specimen have been mounted in the clumsy manner in which small species
are frequently preserved, the articulation might be readily obscured by gum, in
such manner as to be overlooked. The claws of the hind feet of the species
under consideration are more slender and more bristle-like than in H. cuspi-
datus and allies.

81. H. exiguus Aube. Unknown to me. Said by Erichson (Bericht &c in
Wiegm. Arch. 1842, 2, 209) to have as a synonym Anodocheilns maculatus
Babington (loc. cit.) from South America. The genus Anodocheilus is described
as differing from Hydroporus, in having no tooth at the middle of the emargina-
tion of the mentum.

12. H. pull us, oblongus, po3tice vix acutus, flavo-testaceus nitidus glaber,

Louisiana; discovered by Dr. Schaum, to whom I am indebted for specimens.
The vittac of the elytra are quite narrow, the second one is confluent with the
dark colored suture at the base : all thevittas extend nearly to the tip; the under
surface is of a uniform honey yellow color. The faint impressed discoidal line
of punctures of the elytra, which may be traced in all the species, is here more
distinct than usual and runs along the second vitta.

17. H. inconspicuus, oblongus, postice subacutus, flavo-testaceus, sub-

Louisiana; for this very interesting species I am indebted to my friend Dr.
Schaum. The pubescence will distinguish it from the other species, having a
basal stria common to the thorax and elytra. The sides of the thorax are slightly
rounded, and form with the elytra a scarcely perceptible angle.

Ne.w York? given me by Mr. Willcox. The sides of the thorax are rounded,
and form a moderately distinct, but very obtuse angle, with the elytra; the an-
terior fascia of the latter is one-third from the base, and consists of a marginal
spot and a smaller discoidal one ; the second band is at one-third from the tip,
and is straight and regular, extending nearly to the suture ; the elytra in the
only two specimens seen are moderately shining, finely and very densely punc-
tured, but probably vary according to sex.

20. H. 12-1 i n e a t u s, appears allied to H. alpinus and other European species.
The female resembles closely the figure of H. bidentatus (Aube, Col. Eur. 5, pi.
28.) H. laevis Kirby appears to be the same, but he states that no punctures are
visible on the upper surface of the body. In comparison with H. alpinus, our
species is a little narrower, and the sides of the thorax are less curved anteriorly.

21. H. scitulus, oblongus, postice subacutus parum convexus, niger subni-
tidus glaber, capite thoraceque testaceis, punctulatis, punctis maioribus sparsis
intermixtis, hoc versus latera utrinque impresso ad basin transversim subdepresso,
margine apicali et basali nigricante, disco fasciis duabus subinterruptis extror-
sum connexis ornato, elytris margine basali ad humeros dilatata, laterali
lineolisque pluribus flavo-testaceis ornatis, parce punctatis, utrinque fortius bi-
seriatim punctatis, pedibus piceo-testaceis. Long. -13.

One specimen, Eagle Harbor, Lake Superior. Allied to H. septentrionalis of
Europe, but more acute posteriorly, much darker colored above, more coarsely
punctured, and with the two punctured lines of the elytra distinct. The thorax
is broadly rounded on the sides, and forms a distinct angle with the elytra.

22 H. st ri a t el lus, varies in color from the black type, with indistinct
testaceous elytral markings to dull muddy testaceous, with short lines on the
elytra, two discoidal thoracic spots, and the sides of the head fuscous. The under
suiface is black, and the feet dull testaceous, with the posterior tbighs dark.
The impressed striae of the elytra are four on each, and are usually deep, but are
sometimes shallow, though always distinct. It is found at San Francisco and
San Diego, in California, and at Sinta Fe in New Mexico.

23. H. venustus, ovalis convexus, postice attenuatus, confertim subtiliter
punctatus, pubescens, ferrugineus, clypeo ad apicem late truncato, lateribus ob-
liquis, thorace versus angulos postico3 vage impresso, elytris atris, ad medium
paulo latioribus ad apicem oblique subtruncatis, margine fasciis duabus undu-
latls, maculaque versus apicem testaceis. Long. -17.

One specimen from North Carolina given me by Mr. Zimmermann. Very dis-
tinct from all others by the hemi-hexagonal form of the clypeus, which is oblique
each side, and truncate at the apex, with the angles well marked, and the edge
very slightly reflexed. Head and thorax densely finely punctured ; the latter
slightly rounded and distinctly margined on the sides; posterior angles rectan-
gular, broadly vaguely impressed ; the sides make a very obtuse, not very per-
ceptible angle with the elytra. These are black, densely punctured, finely pubes-
cent, moderately convex, broadest about the middle, then narrowed to the apex,
which is obliquely truncate ; the whole margin, two undulated fasciae not

296 [April,

reaching to the suture, and an angulated spot at the apex (as in H. undulatus)
yellow. Body beneath rufo-testaceous, coarsely densely punctured.

27. H. o p p o s i t us Say ; III. prozimus Aube. The length given by Aube is
rather less than that of any specimen seen by me ; the species is very similar to
the preceding, and seems distinguished principally by the margin of the thorax
being a little broader, with the anterior angles not porrected ; the general form
is more obtuse anteriorly, and the color is usually darker, so much so that the
fascia? of the elytra are at times hardly visible. The punctures of the eljtra of
the female are more distinct than in H. undulatus.

29. H. spurius, ovalis, postice magis attenuatus, ferrugineus, pubescens,
capite suhtiliter punctulato haud marginato, thorace confertim punctulato, mar-
gine bisali nigricante, lateribus raarginatis cum elytris angulum haud forman-
tibus, his (maris) confertim subtiliua punctatis striis versus suturam2 vel 3 punc-
tatis parum impressis ; nigris, margine fasciis duabus undulatis, apiceque testaceis.
Long. -18.

One male, from Vermont, was kindly given me by Dr. Harris. This species
closely resembles in form, sculpture and color, H. oppositus, but the
epistoma is not margined. From H. sericeus it is distinguished by its less
elliptical and less convex form, and by the large lateral spot behind the humerus
not being produced so as nearly to unite the two yellow bands which are also
in that species broken up into a series of linear spots hardly connected together.
The male is also less finely punctured than the male of H. sericeus.

30. H. m i x t u s, longior ovalis, postice magis attenuatus, ferrugineus subtiliter
pcrce pubescens, capite subtiliter punctulato, vix obsoletissime late marginato,
thorace minus dense subtilius punctato, apice et basi vix nigricante, lateribus
fortius marginatis, elytris parcius minus s&btiliter punctatis stria suturali punc-
tata, nigris margine fasciis undulatis duabus interrupiis apiceque testaceis.
Long. -17.

One male from Nebraska. Longer and more pointed posteriorly than H. un-
dulatus, with only a very faint transverse line representing the margin which in
that species is quite distinct. The anterior angles of the thorax are not por-
rected, and the punctures of the elytra are larger and more distant.

32. H. s e m i r u f u s, rufo-testaceus parum convexus ovalis postice at'enuatus,
confertissime subtiliter punctulatus, breviter pubescens, capite punctulato, tho-
race latius marginato, cum elytris angulum vix formante, his lineolis quatuor
sutura margine basali macula postica alterisque duabus submarginalibus con-
fluentibus nigris. Long. -16.

Fort Laramie, Nebraska. The first of the lateral spots is placed about the
middle, and is frequently not connected with the others ; the second spot is about
one-fourth from the apex, and internally is usually connected with the common
sutural black spot near the apex. The four discoidal lines are more or less con-
fluent, and are gradually shorter externally ; the outer ones are connected with
a short black basal margin.

33. H. 1 i n eo 1 a tu s, longior ovalis, postice attenuatus, rufo-testaceus sub-
tiliter pubescens, capite subtilissime, thorace subtiliter parce punctulato, hoc
lateribus tenuiter marginatis, cum elytris angulum haud formantibus, margine
basali nigricante, elytris subtiliter punctulatis, sutura vittisque angustis utrinque
quatuor plus minusve confluentibus, maculisque externis duabus angustis nigris.
Long. -08.

Illinois ; Mr. Willcox. The second and fourth black lines of the elytra reach
the base ; the first and third are abbreviated anteriorly ; the two outer spots are
narrow, as if formed by the interruption of a fifth line, of which a trace is some-
times seen on the humerus in the form of a dusky dot. Between the suture and
first line is sometimes seen a very slender black line.

34. H. v i 1 1 a t u s, ovalis, subconvexus, postice suba'tenuatus, rufo-testaceus
parce pubescens, capite postice punctulato, thorace punctulato, apice et basi

punctulatis nigris, vittis duabus margine apiceque flavo-testaceis, vitta externa
ad humerum cum margine confluente. Long. -16.

Fort Laramie, Nebraska. The form of body is exactly that of H. undulatus,
and the epistoma is very obsoletely transversely impressed, as in H. mixtus
above mentioned, but cannot be said to be margined. The inner vitta of the
elytra does not reach the base, but be ids a little outwards at its extremity; to-
wards the tip it is nearly confluent with the apical spot ; the outer vitta com-
mences at the humerus, where it is confluent with the margin, and ends at nearly
one-fourth from the tip ; in or e specimen it is also confluent with the margin at
its posterior extremity. The punctuation is a'ike in all the specimens seen, but
it is quite likely that the females are more finely punctured, less shining and
more pubescent.

35. H. vi ti o su s, ovalis, longior parum convexus, subtilissime punctulatus
postice subattenuatus, subtiliter pubescens, niger, capite thoracisque lateribus
obscure ferrugineis, hoc lateribus marginato, cum elytri3 angulum haud formante,
his nigris margine angusto basali, fasciis undatis duabus interrupts (pnsteriore
indistincta) margine laterali apiceque testaceis, pedibus runs. Long. -15.

One specimen from Illinois ; Mr. Willcox. Of the same form as H. mixtus,
from which it is distinguished by its black under surface. The bands of the
elytra are placed a3 in H. undulatus and its allies, but are much inrerrupted,
and of the posterior one only the lateral spot and a very small discoidal dot are
visible ; the basal margin is testaceous towards the scutellura. The dark red of
the thorax fades imperceptibly into black, in such manner as to induce me tr>
believe, that specimens will be found having a red thorax, with only the basal
margin blackish. The males are probably more distinctly punctured.

41. H. n i g e r. What I consider as Say's species resembles extremely in form,
sculpture and color, H. punctatissimus, but is a little more obtuse anteriorly,
and equally attenuated behind ; it may be distinguished by the lateral margin of
the thorax being hardly conspicuous, while in H. punctatissimus it is
broad and thickened. The head is more finely punctulate, and the epistoma is
not margined.

47. H. subtonsus, longior ovalis, parum convexus, parce pubescens, niger,
ore rufescente, thorace lateribus vix marginatis rufescentibua cum elytris an-
gulum obtusum formantibus, angulis posticis rectis, disco parce subtilius, ad basin

pedibus rufo-testaceis. Long. -125.

Lake Superior and Vermont. Resembles in appearance H. varians and H.
puberulus, and likely to be confounded with them. H. varians is narrower and
more oblong, the sides being almost parallel at the middle, and is entirely gla-
brous. H. puberulus has the posterior angles of the thorax obtuse and very
distinctly impressed. The elytra of the female are less shining and le^s deeply
punctured than those of the female.

Two specimens; Lake Superior. The usual discoidal row of punctures on the
elytra is more distinct than usual towards the base of the elytra; the apical row
of punctures on the thorax is likewise well marked.

298 [April,

Fort Laramie, Nebraska. The first fascia proceeds from the middle of the
humeral spot, runs obliquely inwards, and is dilated into a quadrilateral spot
with elongated angles ; the second fascia is just behind the middle, and is deeply
emarginate anteriorly; neither attain the suture. The anterior black band of the
thorax covers nearly half the surface. In one specimen nearly the whole abdo-
men is ferruginous.

56. H. p u 1 c h e r, ovalis postice magis attenuatus, parum convexus, subtilis-

One specimen from Alabama, collected by Mr. Hentz, was given me by Prof.
Haldeman. The color and markings are almost as in the preceding ; the body,
however, is broader and more obtuse in front and more acute behind ; the sutu-
ral stria is not visible, and the color beneath is ferruginous, though darker than
the red of the feet, head and thorax.

58. H. difformis, longior, obconicus, glaber, ferrugineus, thorace ob-
scuriore, disco subconvexo parce punctulato, distinctius ad latera et basin, late-

tatis, fuscescentibus ad basin pallidioribus. Long. -25.

Mas antennarum articulis 4to late, 3io et 5to anguste dilatatis.

One immature specimen from Georgia. Resembles H. conoideus, but is larger,
and the thorax would never become black. The punctures of the elytra are equal
in size, while in H. conoideus two sizes are intermixed; the dilated third joint
of the antennas is also narrower than the fourth, while in the other species men-
tioned they are of equal breadth.

59. H. sira ilis Kirby. This may be identical with the European H. picipes,
but I have not been able to compare them. I must consider, however, that there
are reasons why the following species should not be considered as H. lineellus of
Europe, which is admitted to be a female variety of H. picipes.

60. H. pi cat u s Kirby. Of this species I found both sexes at Mackinaw,
and on the north shore of Lake Superior. The dull and finely punctured female
hardly differs from the preceding, but the coarsely punctured male has no dis-
tinct elytral striae. Otherwise there is no special difference.

62. H. turbidus, ovalis convexus, piceus, nitidus, capite pedibus thorace-
que fere testaceis, hoc margine apicali et basali infuscato, elytris parum angus-
uore, lateribus obliquis rectis marginatis cum elytris angulum hand formantibus,
antice parce punctulato, postice punctata, elytris modice punctatis, versus latera
rufescentibus. Long. -11.

One specimen from Massachusetts was given me by Mr. Zimmerman. Resem-
bles in characters H. suturalis, but is broader and more convex, and the elytra
are less densely punctured The color is more reddish, there is no diseoidal
spot on the thorax, and the suture of the elytra is not paler.

67. H. patruelis, longior ovalis parum convexus, nitidus subtus niger, an-
tennis pedibus corporeque supra testaceus, fere aequaliter confertim punctatus,

Fort Laramie, Nebraska Similar in form to the Californian H. lutescens, but
less convex, lighter colored, and with the sides of the thorax a little longer and
almost entirely straight, and the elytra more coarsely punctured.

69. II. n u b il u s, longior ovalis, parum convexus, nitidus, subtus niger, an-

truelis, and more finely and densely punctured. The head and thorax are never
clouded ; the vittae of the elytra are sometimes reduced to merely a confused
cloud behind the middle; at other times they are visible nearly to the base; in
the latter case the first and third are a little shorter anteriorly, and the third
and fourth are interrupted befofe the middle. In some there is a slight remnant
of an interrupted submarginal stripe. The thorax is formed as in H. patruelL-.
and is sometimes marked with a central fuscous dot.

70. H. discoideus, latior ovalis fere depressu3 (minus nitidu?) subtus

confertissime punctulatis disco maximo communi infuscatis, sutura lineolisque
anticis paucis pallidioribus, margine late testaceo relicto. Long. *15.

One female found at Fort Laramie. Broader and flatter than the allied
species, and (in case the male should be more shining and more coarsely punc-
tured) distinguished by the large basal spot of the thorax. The head and thorax
are moderately punctured; the dark portion of the elytra is very well defined,
and does not fade at all into the broad pale margin.

73. H. m e 1 1 i t u s , subovatus convexus postice attenuate, flavo-testaceus

ad basiu maculis lateralibus duabus alteraque subapicali pallidis. Long. -09.

One specimen from Vermont, collected by the late Prof. U. B. Adams. By the
form of the epistoma it resembles H. hybridus, but is much smaller and more
ovate in form, while the spots of the elytra do not form transverse fascia?, though
those that remain are referable to that style of marking.

Lake Superior, two specimens: very similar in all its characters to the next,
and only distinguished by the narrower elytra, and wider and less convex
thorax: the latter is somewhat less densely punctured, but the basal fovea is
obsoletely prolonged each side. As in the four next species the stria? of the
elytra are hardly impressed, their punctures are very distinct anteriorly, but grow
small towards the tip, till they are hardly larger than the intervening rows of
small points. The head just behiud the eye is armtd each side with an obtuse
not very distinct tubercle.

One specimen found at San Jose, California, Related to the two preceding
species, bnt the punctures of the elytra are larger and somewhat connected by
transverse r, gae. The lateral teeth of the thorax are more conspicuous, and the
basal fovea is faint: the head is about equal in width to the thorax, and has
behind each eye a scarcely distinct obtuse tooth.

Lake Superior: the sides of the thorax are smooth anteriorly, but have a few
email teeth near the posterior angles, which though obtuse are quite distinct.
It is distinguished from the next principally by the thorax being very little
broader than its length: the thorax varies in color becoming sometimes almost
rufous.

Lake Superior, very abundaut: the serrations of the thorax are less conspicu-
ous towards the anterior angles. I do not feel certain that the former species
should be separated from this: I can find no difference except the relative pro-
portions of the thorax, and as both are found in one locality and mingled to-
gether, it is quite possible that they are really different sexes of one species; in
which case the name appended to the present description must for obvious
reasons be retained.

One specimen, Lake Superior; fiom the next two species this is distinguished
by the form and coarser punctuation of the thorax. As in C. compta, and in the
next two, the beautifully regular arrangement of the hairs on the elytra causes
the interstices between the strice of quadrate punctures to appear in some lights
very finely carinated.

Middle and Southern States : rare. Varies in having the elytra piceous, with
two large testaceous rounded spots on each, one behind the base and the other
behind the middle. The 9th joint of the antennae is hardly larger than the 8th,
which, together with the absence of pubescence, gives to the insect a peculiar
appearance, and suggests even the establishment of a separate genus for its re-
ception.

In the next species, however, the external appearance of the ordinary species
of Corticaria is resumed, though the antennas are as in the present one.

One specimen found at the Colorado River in California. The hairs of the
elytra are precisely as in the many species of the division A, but the punctures
of the normal striae are very small, hardly larger, in fact, than those of the in-

quite distinct; the two dorsal carinas are parallel anteriorly, and between them
is eeen an oval fovea : towards the base they converge, and are continued
through the transverse impression.

The posterior impression of the thorax is deeper at the sides and in the middle,
so that it appears like three foveas transversely connected.

Notes derived from observations made on the Birds of New Mexico during the

years 1853 and 1854.

By T. Charlton Henry, M.D., U. S. Army.

The following observations were made by the writer, on the Ornithology of
that portion of New Mexico lying south and north-west of the Jornada del Muerto,
a portion of country differing very essentially from that situated in the vicinity
of Santa Fe. In special, or nearly special, reference to the Ornithology of the
latter, it will be recollected that Col. McCall, late Inspector General, U. S.
Army, published, somewhat more than two years ago, in the Proceedings of the
Philadelphia Academy of Natural Sciences, an interesting and able article. It
will be observed that the writer in the present case, having devoted his entire
leisure to his favorite pursuit for a period of more than two years, while stationed
at Forts Fillmore, Webster and Thorn, each in turn, has succeeded in adding
largely to the list published by Col. McCall, as above referred to.

A word relative to the topography of the several locations where the observa-
tions were made.

Fort Fillmore is situated on the eastern bank of the Rio Grande, south of
Santa Fe two hundred and seventy-five miles, its level above the sea being several
thousand feet less than the latter place. Small mesquit and cotton-wood, with
more or less " tornilla," is the principal wood to be met with in its locality.
The soil is sandy, except in the bottom land, where alluvial deposit exists to a cer-
tain extent, of argillaceous character, and black loam. Fifteen miles north-east of
the Fort are the Organ Mountains, but no investigations was the writer able to
make there during the four months he was stationed at Fort Fillmore ; the size
of the garrison, to which he was Post Surgeon, precluding the practicability of
his absenting himself therefrom for any length of time. August, September,
October, November and part of December, were passed at Fort F. The writer
was then ordered to Fort Webster, near the Sierra de los Mimbres and near the
copper mines, the post being built on the banks of ihe Rio de los Mimbres (River
of Willows) a small, rocky and beautifully clear stream.

This location was in the very heart of the mountain ; the ground very elevated,
and the soil along the stream exceedingly rich, being much of it black muck, with
scarce a particle of clay in its composition. On the upland, where grew in pro-
fusion the nutritious " gamma grass," a limestone base was covered lightly with
vegetable deposit. The face of the country was plains, narrow valleys and high
mountains, alternately.

The timber consisted of white cedar, (Juniperus albus,) pinon, (Pinus mono-
phyllus,) white pine, (P. altissimus,) scrub oak, (Q. olivaeformis,) and black wal-
nut, among the mountains ; along the brook, cotton wood, white water ash and
box alder, the latter rather sparse. The geological character of the mountains
is principally limestone, associated with traces of iron and lead, and silver not
unfrequently found in combination. Spar, unlike the composition of the Organ
Mountain range near Fort Fillmore, very little or none. Copper also, in the
form of carbonate, abounds in the vicinity ; also, as usual, associated with a cre-
taceous base; black volcanic rock, to a small extent, is to be met with.

At Fort Webster the writer passed more than a year, when he was removed
to Fort Thorn, situated on the Rio Grande, some fifty miles above Fort Fillmore.
Soil, timber, &c, are all similar to that found about Fort Fillmore, with a slight
difference only in temperature.

With these few preliminaries, which the writer deems of some service, as
bearing in a measure upon the character of the haunts frequented by certain
birds, many species of which, in this region, although found in great abundance
in one locality, yet in another, a few miles only distant, are never met with,
he will proceed to note every bird actually met with, during nearly three years
sojourn in New Mexico, of which he has, in most every instance, procured
specimens.

CATHARTES.

I. C. aura. Common during the summer months, especially along the Rio
Grande; among the mountains fewer. In winter rarely seen. Most abundant
in the spring and fall.

BUTEO.

2- B. borealis. Breeds rather abundantly; common everywhere. Numerous
specimens obtained.

3. B. Pennsylvanictjs. Rarely met with. One near Fort Fillmore shot in Sep-
tember.

4. B. lagopts. Not rare. Several specimens obtained. Feed much upon mal-
lards and other ducks. Observed only once on the Rio Mimbres ; not unfrequently
shot while duck hunting along the Del Norte.

HALI^TUS.

5. H. leucocephalus. But t wo or three pair seen at Forts Fillmore and Thorn,
during the winter only. One young male in brown plumage obtained at Fort
Webster ; the only one seen there.

PANDION.

6. P. hali,etus. Two or three seen at each station ; one shot. Apparently not
numerous. The maddiness of the Rio Grande, and the small size of the few
clear streams found in the country, will probably account for it ; in the first case
their prey bein^ not readily seen from above ; in the second, the few fish found
being very small.

FALCO.

7. F. columbarius. Occasionally seen only ; numerous nowhere. One obtained
at Fort Webster.

8. F. sparverius. Common everywhere. Resident.

ASTUR.

9. A. Cooperi. One shot near Fort Webster; no other observed.

10. A. fuscus. Common among the mountains; very rarely seen elsewhere.
Several obtained.

CIRCUS.

II. C. cyaneus. Extremely common everywhere. Prey much upon the par-
tridges (L. Gambelli) and also ducks.

SURNIA.

12. S. hypogcea. A few observed upon portions of the Jornada del Muerto.

OTUS.

13. O. vulgaris. Quite common in the fall along the Del Norte. Observed
among the mountains but twice.

BUBO.

14. B. Virginianus. Common in both localities. One shot very nearly white.

CHORDEILES.

15 C. Virginianus. Very common everywhere from April to July ; makes its
first appearance in the latter part of March.

CAPRIMULGUS.

16. C. Nuttallii. Found both along the Rio Grande and Mimbres; much more
common at the latter place. Arrives and migrates in the latter part of October.

308

[April,

HIRUNDO.

17. H. purpurea. Not very common. Observed only at Fort Webster. Ar-
rives about the middle of April and remains about two months only.

18. H. bicolor. Very common throughout New Mexico. Arrives about the
10th of April, and migrates about-the last of August.

19. H. thalassina. Common, more particularly along the Mimbres. Arrives
early in April, and leaves by the 5th of August.

20. H. rufa. Quite common along the Rio Grande. Time of arrival a few
days later than H. fulva; migrates about August 15th. A few only seen on the
Mimbres.

21. H fulva. Observed only at the Mimbres. Not numerous. Arrives the
last of March and migrates the last of July.

22. H. riparia. Common botb in the Valley of the Del Norte and among the
mountains. Arrives soon after H. thalassina, and migrates somewhat later.

MUSCICAPA.

23. M. verticalis. Found in abundance among the mountains. Arrives at
Fort Webster March 25th, and leaves about the 20th of August. Never seen
along the Valley of the Rio Grande.

24. M Saya. Seems to take the place of the Verticalis along the Rio Grande.
Common at Forts Fillmore and Thorn. Arrives the 1st of February, and is not
seen after the 25th of July, unless very rarely ; one seen in January.

25. M. nigricans. Rather common among the mountains. Occasionally seen
along the Del Norte. Always affects the neighborhood of streams. Arrives
31st of March ; not observed after the 20th of July.

26. M. pusilla. Not rare along the mountain streams ; often observed at Fort
Webster. Arrives late in May, and migrates the last of July.

PYROCEPHALUS.

27. P. rubineus. One shot in May at Fort Webster ; the only specimen met
with ; a male in full plumage.

PTILOGONYS.

28. P. Townsendii. Very abundant during the winter months only, about
Fort Webster, where they always frequent the neighborhood of cedar trees and
feed on their berries. Arrive in October in considerable flocks, and soon sepa-
rate into pairs or threes ; migrate the last of March. They appear to possess no
power of song, although in March they frequently utter a peculiar note, very
short and interrupted. Their call note may well be compared to the slight creak-
ing of an ungreased carriage wheel. Their call note differs from their attempts
at singing in spring. Seem very retiring, and are usually met with in shady
glens near a stream where cedars abound.

They do not nest in the neighborhood of the Mimbres, nor do they migrate in
the spring in flocks, as far as 1 can ascertain. Never met with along the valley
of the Rio Grande.

29. P. nitens. Three or four pair observed about Fort Webster, and shot in
June, 1853. First observed May 25th; none seen after July. Not seen on the
Rio Grande. Nest on the Mimbres.

TOXOSTOMA.

30. T. rediviva. Found rather abundantly about Fort Fillmore. Frequents
the mesquit exclusively. More observed during the months of October and
November than during the summer. A few seen during the month of August.
Am unable to say whether it breeds here. Rarely seen after December. Two
or three seen at Fort Thorn during December 1853. Never observed on the
Rio de los Mimbres.

1855.] 309

CULICIVORA.

31. C. ccerulea. Rare throughout the country. A few seen at the Mimbres
during the month of April ; first observed on the 12th of that month. Probably
does not breed here.

SYLVICOLA.

32. S. coronata. Very abundant everywhere '"ring the months of April and
October. First observed at the Mimbres, April 2d.

33. S. striata. One or two only observed in April at the Mimbres.

34. S. ccerulea. One observed at the Mimbres during the latter part of April.

35. S. jestiva. Common throughout the country in summer. Arrives in the
early part of April, and migrates southward the latter part of July.

36. S. nigricans. One shot May lOthon the Mimbres, the only one observed
at any tump.

37. S. Canadensis. A few observed on the Mi nbres, and one along the Rio

less numbers along the valley of the Rio Grande. Arrives about the 1st of April
and disappears the latter part of July.

HELINAIA.

40. H. chrysopteua. One only seen near Fort Thorn in April, 1854.

CERTHIA.

41. C. FAiiiLiARTs. Vury common among the mountains in summer, where it
probably breeds. Never seen, except in winter, along the valley of the Rio
Grande.

TROGLODYTES.

42. T. obsoletus. Very common among the mountains in summer, where it
breeds. Not seen on the Rio Grande. Arrives at Fort Webster by the 15th of
March, and disappears the last of July.

43. T. Americanus. Occasionally seen only in winter and late in fall. Two
or three obtained at the Mimbres and Fort Fillmore.

44. T. palustris. Very common in summer everywhere, but most abundant
along the small mountain streams where there are marshy shores. Breeds in
the territory. Many winter along the Rio Grande.

PARUS.

45. P. minimus. Common among the mountains. Resident. Not met with
along the river.

46. P. bicolor. Common in winter among the mountains. Not on the Rio
Grande.

47. P. Wollweberi. One only seen ; shot on the 10th of May, at Fort Webster.

REGULUS.

48. R. satrapa. Common along the Sierra de los Mimbres. Resident. Some-
times seen in winter along the Rio Grande.

49. R. calendula. One or two met with among the mountains.

310 [April,

SIALIA.

^ 50. S. occidentals. From October 20th to March 10th abundant, both among
the mountains, where they feed on the cedar berries, and along the river, where
they make the berries of the miseltoe their food.

51. S. arctica. Much rarer along the Rio Grande than among the mountains,
where they breed. Arrive about the ]0th of February, and remain in the river
valley but a fortnight or three weeks; among the mountains some two months,
or until one brood is reared, after which they take their departure. Once seen
as early as January 29th.

CINCLUS.

52. C. Americanus. Very abundant on the Rio Mimbres during the whole
winter, from the 10th of October until the 1st of April. Never seen along the
Rio Grande, nor any where in the summer.

55. T. migratoritjs. Abundant on the Mimbres during the fall and winter.
Very few seen after May, till October. Very f w ever seen on the Rio Grande,
and when seen, only in winter. Their range confined to those parts of the country
only where cedars abound.

56. T. solitarius. A few resident throughout the country.

57. T. nanus. Very common in April on the Rio Grande, both at Forts Thorn
and Fillmore. Probably migrates farther northward.

ANTHUS.

58. A. ludovicianus. A few straggling flocks observed every spring and
fall, both in high and low ground.

ALAUDA.

59. A. occidentals. Found during the spring and winter, chiefly on open
plains and elevated ground. Not resident.

PLECTROPHANES.

60. P. McCownii, (Lawrence). Very large flocks everywhere, especially
about the margins of the Rio Grande from the 10th of October to the last of
April. Their habits much resemble those of P. nivalis. Never saw any in full
summer plumage, as they do not breed here.

[Description by George N. Lawrence, Esq. Head before the New York Lyceum of
Natural History, 8th Sept., 1851, and published in Proceedings of that Society.

remain about two months. Found only among the mountains.

62. E. graminea. Only one met with on the Mimbres, on the 8th of January,
during a thaw.

63. E. passerina. A few seen on the Rio Grande during the latter part of
February. Two obtained.

64. E. socialis. Arrives in small numbers March 4th, and remains in the
country till the last of July. Not abundant.

NIPHEA.

65. N. Oregona. Among the mountains. A few seen during the summer,
where during the winter they are extremely common. It is fownd also in con-
siderable number along the river valley during the winter months.

LINARIA.

66. L. fines. Common everywhere, except in Summer, through the
country.

CARPODACUS.

67. C. familiaris. Rather common during the months of April and May,
both in high and low grounds, feeding on the buds of the cotton wood, (P. Can-
adensis.) Breeds, (as observed by Col. McCall,) about Santa Fe and the vi-
cinity.

C. obscures, (McCall.) Three shot near Fort Webster ; found in winter,
among the pines upon a mountain. Male and female of similar plumage.

CARDUELIS.

68. C. Magellamcus. Principally observed along the Rio Grande in the
month of September. Its sojourn is very short. A very few seen in May at
Fort Webster. Probably breeds among the mountains.

FRINGILLA.

69. F. melodia. Common during the winter and early spring, but not very
numerous.

70. F. i.eucophrys. The most abundant species of sparrow in New Mexico
during the whole year, but most numerous in winter. Never have met with
nest or eggs.

PIPILO.

71. P. arctica. Throughout the summer remains among the mountains.
Common along the Rio Grande in the winter months.

72. P. fusca. Like its congener, a constant resident in the territory, but
unlike in never frequenting the river valley. Affects the locality of cedar
bushes and mountain canons ; hence termed the Canon Finch. (See Cassin's Il-
lustrations.) Found at Fort Webster ; equally common with P. Arctica ; very
shy and retiring in his habits; never found in flocks.

CORYDALINA.

73. C. bicolor. During the Spring of 1853 I observed a few specimens of
this species. They appeared as if migrating, and I never since met with others,
either in high or low land. Those seen were near Fort Webster.

COCCOBORUS.

74. C co3ruleus. Quite common in Summer along the river valley. A
few seen on the Rio Mimbres. They no doubt breed in the territory.

75. C. melanoleucus. A few seen and obtained along the Sierra de los
Mimbres in the latter part of May, 1S53, when they were in full song. Never
seen in winter ; rare.

312 [April,

COCCOTHRAUSTES.

70. C. VESPERiiNA. A few seen among the mountains in March, 1853, and
two specimens obtained.

PYRANGA.

77. P. aestiva. Rather common in summer along the Rio Grande. One
or two met with in the mountains, where they are rather rare.

MOLOTHRUS.

78. M. pecoris. Rather common everywhere from April to November.
Not seen in winter.

AGELAIUS.

79. A. phcenicetts. Common throughout the year. Breeds in the terri-
tory.

80. A.xanthocephalus. Verycommon during the greater part of the year.
Not seen in winter.

QUISCALUS.

81. Q. Breweri. Very common during the early spring and fall months.

STURNELLA.

82. S. neglecta. Common throughout the year. Most numerous in the
valley of the Del Norte.

CORVUS.

83. C. corax. Exceedingly abundant, especially in winter. Breeds among
the mountains, chiefly, but not exclusively.

84. C. Americanus. Very rare, according to my observation ; but two met
with, and at Fort Webster.

GARRULUS.

85. G. stelleri. A common jay among the mountains.

86. G. ui.tramarinus. The most abundant species ; found in fall, not unfre-
quenily along the Valley of the Rio Grande, but exceedingly numerous among
the mountains.

87. G. CRrsTATrjs. Found about the woods bordering the northernmost por-
tion of the Rio Grande. This I state not upon my own, but upon the authority
of a person perfectly familiar with the blue jay of North America.

GYMNOK1TTA, (Prince de Wied.)

88. G. cyan rppiiALA. This extremely graceful and beautiful shaped jay
I have met with along: the Sierra del los Mimbres range, some five or six times.
It is invariably found in flocks of forty or more individuals; very shy and diffi-
cult of approach. This is the Cyanocorax Cassini of Col. McCall. I never
met this bird along the valley of the del Norte. The peculiar taper bill of this
species is quite characteristic ; very unlike that of the general family Corvinae
of Wilson. Its wings are also far wider in proportion than it is common to see in
the jay family ; and the tout ensemble of the bird, except its bill, would seem
to my mind to ally it nearly to the Nucifragre.

NUCIFRAGA.

89. N. CoLTJMBrANA. Quite common near Fort Webster, during the months
of November and December. Found mostly among the pinons, (Pinus mono-
phyllus.)

LANIUS.

90. L. LiiDovicrANis. Common and resident in the territory, but most abun-
dant in the winter months.

1855.] 313

VIREO.

91. V. gilvus. Common ; the only one of this family ever obtained by me
in New Mexico. From March 25th to August 15th.

ICTERIA.

92. I. viridis. A few seen during the spring and summer of 1853 on the
Rio Mimbres, where they appeared to breed. Perhaps this species may be the
longlcauda of Lawrence.

BOMBICILLA.

93. B. Carolinensis. One flock observed frequenting the wild currant
bushes near Fort Webster, in June, 1853. I obtained two specimens in order to
prove their identity. Never seen elsewhere in the territory.

SITTA.

94. S. Carolinensis. A few only met with ; mostly about Fort Fillmore.

95. S. Canadensis. Not rare among the mountains; much more common
than the former.

96. S. pygmea. Several seen, and two shot near Fort Fillmore in 1853 ;
none since seen.

TROCH1LUS.

97. T. anna. Very abundant among the mountains in August and Septem-
ber; their haunts being flowery canons, in the neighborhood of rocky streams.
Rarely met with in the valley of Del Norte.

ALCEUO.

98. A. alcyon. Not very common ; seen principally along the Rio de los
Mimbres ; the Rio Grande, in lat. below 30° being too murky a stream to suit
his tasre.

PICUS.

99. P. THYROiDETjs. Found only occasionally in fall and winter, among the
mountains. Three specimens obtained. Seem quite gentle, and are readily ap-
proachable. Never seen, except in the vicinity of or among pine trees.

100. P. varius This bird, rarely found elsewhere than in the mountains, is
rather common in the localities which it affects.

101. P. formicivorus. Quite rare; met with among the highest pine-clad
mountains only. But the specimens were very shy and difficult of approach,
even when perched on the highest trees.

102. P. villosus. Quite common everywhere.

103. P. torqtjatus. Not very rare in the mountains. Generally found
among pine trees. Their shyness is very marked.

104. P. scalaris. Not rare along the Rio Grande. Affects principally the
mesquit, (P. glandulosa,) as a resort. Not common in the mountains. Seems
to take the place of P. pubescens.

105. P. Mexicanus, or collaris. A very common species throughout the ter-
ritory ; the most so of any oth£r.

COCCYZUS.

106. S. Americanus. A few seen in summer, along the Rio Grande del
Norte.

314 [April,

COLUMBA.

107. C. fasciata. Common in the mountains during the months of Septem-
ber and October, when they feed upon acorns ; very shy ; a few breed near the
old copper mines near Fort Webster. The writer has met this species on the
Mimbres in June, feeding on the berries of the wild currant.

ECTOPISTES.

10S. E. Carolinensis. Extremely abundant everywhere, especially during
the summer months. Large numbers resident.

MELEAGRIS.

109. M. gallipavo. Common through all the more unsettled parts of the
territory, both in high and low land. The species found here has the upper
tail coverts broadly tipped with white.

CYRTONYX.

110. C. massena. Not rare in the mountains; occasionally seen along the
Rio Grande- Lie well to the dog, and afford much sport in shooting them.
Their favorite resorts are along mountain sides, where they procure various
kinds of insects, by grubbing them out with their bills, at the roots of the grass.
Never detected vegetable matter in the stomachs of any. This species often
hides behind stones and in hollows after being flushed.

LOPHORTYX.

111. L. Gambei.il The common quail of this country; found both in the
high and low land. They are said not to lie well to a dog, but I have proved
that this is the case only in bright weather ; for often in cloudy days 1 have seen
them lie well to a well-broken pointer. Their food, unlike the Massena par-
tridge, is exclusively, almost, vegetable. The berries of the miseltoe in win-
ter seem to furnish their principal food.

CALLIPEPLA.

112. C squamata. Found only in high ground, elevated plains or mountain
sides. They appear to be far the shyest of their species. Their flesh I prefer
to that of either of the other. Capt. J. P. McCown, U. S. A., in his notes upon
this bird, as observed in Texas, published by Geo. N. Lawrence, Esq., says he
"thinks they never affect open plains." But as far as my observation goe3,
(which is quite extended in regard to this species) although generally found in
ihe neighborhood of bushes, particularly mesquit and wild sage, I have of-
ten seen them feeding on perfectly open rocky hills.

GEOCOCCYX.

113. G. viaticcs. Quite common among the mesquit bushes everywhere along
the Del Norte. Rarer in the mountainous parts of the country.

TETRAO.

114. T. obscurus. One flock, only seen near the summit of the Sierra de
los Mimbres. 1 state this fact on good authority, as I did not see the birds
myself. All, however, agree they are not rare in the northern portions of the
territory.

FQL1CA.

115. F. Americana. Exceedingly common in every slough and pond.
Resident.

ORTYGOMETRA.'

116. O. Carolinus. A few seen passing through the country in the Spring
and Fall — not abundant. A few winter on the Rio Mimbres.

118. G. America ntjs. Quite common during March and October, on their
northward and southward flight — principally the young. The adults in full
plumage only occasionally seen, and never in large flocks.

CHARADRIUS.

119- C. vocifert's. Very abundant during the year, with the exception of
the months of November, December, and January. High as well as low

grounds.

TR1NGA.

120. T. Bartramii. Not very common — a few only seen alomr the grassy
shores of the Rio Grande in Autumn and Spring. Probably do not breed here.

121. T. Schintzii. Two shot near Fort Fillmore, in October, '52. None
else seen.

122. T. prsiLLA. Rather common — but in small flocks during the summer
months — along the Rio Grande, and a few seen on the Mimbres.

123. T. arenaria. A few o( this species seen in September, upon marshy
grounds, near Fort Thorn.

Forts Webster and Thorn.

125. T. solitarius. About as numerous as the last named variety.

12G. T. flavipes. Quite abundant in the months of August and September
in marshes bordering the Rio Grande.

127. T. vociferus. Found along the Rio Grande in small numbers during the
spring and autumn months. Not seen in flocks as the former, but in parties of
two or three, and more frequently singly.

SCOLOPAX.

128. S. Wilsonii. Winters on the Rio Mimbres, in small numbers. Not
abundant anywhere, but more or less met with along the Del Norte in fall and
spring.

129. S. DRUMMONDit ? Found in pairs, occasionally, along the marshes and
sloughs bordering the Rio Grande,*in September and October. Some eight oi ten
specimens shot by the writer.

RECURV1ROSTRA.

130. R. Americana. Every spring and fall, a few found on the Del Norte
and its vicinity.

HIMANTOPUS.

131. H. nigrxollis. During fall and spring occasionally seen, but by no
means a common species. Never seen on the Rio Mimbres.

NUMENIUS.

132. N. i.oNGiRosTRis. Not uncommon during the months of September and
April, particularly on the Laguna del Muerto.

133. N. Hudsomcus. One only seen and shot on the Rio Grande, near Fort
Thorn, in the spring of '54.

IBIS.

134. I. FALciNELLrs. Two shot at Fort Fillmore in May, in full spring

TANTALUS.

135. T. loculator. A few seen along the Rio Grande, during the months of
September and October. More common on the sloughs near El Paso del Norte,
where I saw a moderately large flock in August '54.

ARDEA.

136. A. nycticorax. Quite common in summer.

137. A. lkntiginosa. Not very common. A few seen every summer, but
only on the Del Norte.

138. A. exilis. Four or five seen during the summer of 1854, near Fort
Thorn. Two specimens obtained.

139. A. virescens. Not very rare in summer.

140. A. herodias. Quite common throughout the year. Resident.

141. A. candidissima. Common along the Rio Grande in summer only.

ANSER.

142. A. Canadensis. Resident. Breeds on the Rio Grande. Found in tolerable
abundance throughout the winter. Not so common in summer. A few breed
along the river.

143. A. albifrons. I have never seen but three of this species, of which I
shot two at Fort Thorn in the fall of 1854. Said to be quite common a hundred
and fifty miles higher up the Rio Grande del Norte.

144. A. hvperboreus. About as common as the albifrons. Few seen below
Albuquerque.

ANAS.

145. A. boschas. Extremely common everywhere in winter. Many resident
throughout the year. Breed in greater or less number.

146. A. obscura. Rare. A few seen on the Rio Grande every spring, on
their passage north.

147. A. strepera. This beautiful duck is even more common than the Mal-
lard in ponds adjoining the Rio del Norte, but only during the spring and winter
months. Never observed after April till the last of October. Rare on the Rio
Mimbres.

148. A. Americana. Not rare, both along the Del Norte and Mimbres in fall
and winter.

149. A. acuta. Much rarer than the last. A few seen every spring and fall
on the Del Norte.

150. A. sponsa. But two or three ever met with, and only on the Rio Mimbres.

151. A. Carolinensis. Quite common during the spring and fall along the
Del Norte. Many winter on the Munbres. Not met with in the summer.

152. A. discors. Not as common as the last.

153. A. Rafflesii. This beautilul duck is the most common summer duck
found between latitudes 31° and 33°. Rarely seen in winter. Probably breeds
in the section where it abounds in summer. Very common on the Mimbres and
Del N Tte. it is usua ly lound among the sedge that borders sloughs near a water-
course, where its plumage, so closely resembling the reddish brown of the withered
sedge of last year's growth, renders it observed vvith difficulty, thus carrying out
that admirable rule in nature's handiwork that so generally prevails, viz., as-
similation of the plumage of birds to the color of the haunts they affect.

154. A. clypeata. Rather rare. Occasionally seen in fall and spring on the
Del Norte and Mimbres.

1855.] 317

FULIGULA.

155. F. yamsneriana. Found not unfrequently in fall and u inter about the
brackish sloughs near the Del Norte. Are the least shy of any species, and
almost invariably found in excellent condition for the table. Never seen on the
Mimbres.

156. F. feei.va. But three or four ever obtained.

157. F. MAR! la. Rather common alonsr the Rio Grande in winter. Also fre-
quents to a considerable extent brackish sloughs.

months.

COLYMBUS.

169. C. glaciat.is. A female obtained near Fort Thorn in the month of Oc-

The muddiness of the waters of the Del Norte below latitude 31° prevents, no
doubt, its being found at all common.

Analyses of the Meteoric Iron from Tuczon, Province of Sonora, Mexico.

By In. F. A. Gexth.

The masses of Meteoric Iron of Taczon, first brought to notice by Dr. J L
Le Come, (SHI. Journ. II. Ser. XIII. 289,) and afterwards more fully described
bv Prof. C. U. Shepard, (Sill. Journ. II. Ser. XVIII, 369,) were also mentioned by

318

[April,

Dr. J. L. Smith in his Memoir on Meteorites, published in the last number of the
same Journal, March 1855, in which he gives the analysis of a piece cut from
one of the huge masses by Lieut. Jno. G. Parke, of the IT. S. Topographical
Engineers. Several months ago I had finished the following analyses of the
same meteorite, (which will be found to agree very well with those of Dr. Smith,)
but various circumstances have heretofore prevented my presenting to the
Academy the results of my examinations, which were made with pieces taken
from the specimen presented to the collection of the Academy of Natural Sciences,
by Dr. Heermann.

To the descriptions of this meteorite given by D. C. U. Shepard and Dr. J. L.
Smith, I have to add only a few words.

The pieces which I have examined were not passive, as Prof. Shepard remarks,
but dissolved readily in nitric acid, and also immediately precipitated metallic
copper from the solution of the sulphate. On dissolving it in chlorohydric acid,
only a slight odor of carburetted hydrogen was perceptible, and no gas evolved,
which precipitated an ammoniacal solution of chloride of copper ; a very small
quantity of Schreibersite separated in form of a brownish powder.

On evaporation of the solution by nitric acid in a waterbath and subsequent
moistening of the dry mass by chlorohydric acid, all the substances were taken
up, excepting a small residue of siliceous matter. This dissolved partly on boil-
ing with carbonate of soda, leaving a residue, which I took for a feldspathic
mineral ; the quantity obtained, however, was too small for further examination ;
the small quantities of alkalies, lime and alumina speak in favor of this view,
and indicate that the residue insoluble in carbonate of soda is labradorite, a
mineral which is partly decomposed by acids. The silica, soluble in carbonate
of soda, results undoubtedly from the decomposition of olivine. I was particu-
larly cartful to obtain the whole quantity of cobalt and nickel, and have, there-
fore, not separated the sesquioxide of iron br carbonate of baryta, which method
is not quite correct; but have precipitated the boiling solution, containing sesqui-
oxide of iron, oxide of cobalt and nickel, magnesia, etc., and a sufficient quan-
tity of chloride of am -nonium by ammonia, and immediately afterwards acidulated
by acetic acid, boiled and filtered. All the other determinations were made as
usually.

The following results were obtained.

Notice upon the viviparous Fishes inhabiting the Pacific coast of North America, with

an enumeration of the species observed.

By Charles Girard.

The observations which we have traced upon the genital apparatus of the
female, have satisfied us that there exists an ovarian sheath or sack, which,
during the early period of pregnancy, is an elongated and subcylindrical tube,
containing the ovaries proper, two in number, each of which consisting of two,
three, or more vascular membranes, attached by their upper edge to the upper

1855.] 319

floor or roof of the sheath, forming either one, two, or more pouches (according
to the number of these membranes) of the same length as the sheath itself, widely
open beneath, though not in a direct communication with one another, since the
membranes hang loosely down, resting on the lower floor of the sheath.

The eggs are formed within the texture of the ovarian membranes themselves.
We have examined the ovaries of Ennichthys heermanni, when the sheath, within
which they were contained, was not larger than an ordinary quill. Numerous
eggs could be observed in a very immature state, appearing to the naked eye
like minute dots. Under the microscope, they exhibited evident traces of the
germinal vesicle, surrounded as yet with a very scanty supply of vittiline sub-
stance.

The sheath and the ovaries are gradually increasing in bulk, as the eggs them-
selves first increase in size and the embryos afterwards. The sheath is a mus-
cular membrane chiefly, whilst the ovarian membranes, we have stated, are
altogether vascular.

When miture, the eggs either fall into the space between the membranes or
ovarian pouches, or else remain attached to the ovaries until the embryos issue
out of them. We are inclined to think that they drop into the pouches as eggs.
At any rate, we found very young embryos loosely contained in the ovarian
pouches, when no trace of the egg membrane could be seen within the tissues of
the ovaries in the shape of corpora lutei or graffian vesicles. Whatever be the
case, numerous eggs or embryos may be observed within one pouch. The young
thus remain together until grown to a considerable size, when, filling up the
space in a more compact manner, the ovarian membranes, in their nature very
expansive, will extend a fold between each embryo. In this manner every indi-
vidual young, when removed sideways from the ovary, appears to the operator
as if enclosed in a separate cavity, pouch, or follicle, of the ovary, whilst, in
reality, the membranes maybe stretched out or extended, and the entire progeny
loosened from all adherence or connection with them.

The male organs of generation consist of two spermaries, a right and a left,
perfectly independent from one another, having each its separate duct, dis-
charging their contents into an elongated cloaca, into which the bladder, like-
wise, empties its contents. This cloaca communicates with the exterior by a
subcircular opening, the edge of which being rather protruding. Such is that
apparatus — the same in its general structure as in the other osseous fishes.
There is no sheath enclosing the two spermaries, and this fact throws a con-
siderable light upon the morphology of the ovaries : the latter being in fact two
in number, but so closely connected together as to simulate a single organ. Thus
the general disposition, not the plan of structure, of these organs, is adapted to
the mode of reproduction — a single sheath being a more simple adaptation than
two, one for each ovary.

How the mechanical act of fecundation takes place we are not prepared to say
from direct observations ; the eggs themselves must be fecundated within the
ovarian sheath ; a copulation of some sort is therefore required, and it is not
improbable that at this period the eggs have dropped from the ovarian mem-
branes into the pouches, or spaces between these membranes, in which they are-
freely floating.

The hatching of the embryos takes place at an early period. After leaving
the egg shell, they have an abdominal bag containing the remaining yelk, which
is to be gradually absorbed during a period when neither the mouth nor the
esophagus are formed ; the fins have not yet appeared. The visual organs begin
with a deposition of an external layer of black pimentum, in every respect similar
to the same organs in invertebrata. The head is anteriorly rounded, and the
cleft of the mouth not yet apparent at the period when the fins begin to develop,
The caudal has the start over all other fins ; its posterior margin is first lanceo-
lated, then rounded, with a convexity gradually diminishing until it is perfectly
straight, when a gradual emargination commences, and from a slight crescent
reaches the forked shape which it assumes in the adult. The soft and articulated
portion of the dorsal and anal fins, next assume a development reaching extra-

320 [April,

ordinary proportions, which they again gradually lose so soon as free from
parental sheltering. The posterior portion of these fins is especially to be no-
ticed, as longer or deeper than the anterior portion (the reverse of what we ob-
serve in the adult,) and extending generally beyond the base of the caudal fin,
a character, therefore, not exclusively proper to the genus Rhacocheilus. The
spinous portion of these same fins, on the other hand, develop but slowly and
gradually, reaching their full growth at a late period. The ventrals and pec-
torals are likewise tardy in their appearance. The scales are fully developed
before the young leave the ovary.

Descriptions of New Species of Birds from Western Jfrica, in the collection of the
Academy of Natural Sciences of Philadelphia.

By John Cassin.

1. Bareatula Duchaillui, nolis.

Form. — About the size of Bucco philippensis, Briss. Wing with the first quill
spurious, fourth longest, but slightly longer than the fifth, tail somewhat rigid,
legs moderate, tarsi rather long, toes long.

Dimensions. — Total length (of skin) male 5| inches, wing 3}, tail If inches.

Colors. — Throat, neck before and breast glossy blue-black, which color bifur-
cates and is continued on each side of the abdomen. Head above scarlet, aline
from above the eye running downwards, on the side of the neck, light sulphur
yellow. Upper parts black, with a steel blue lustre, the lesser wing coverts and
many feathers of the back with small cordate and oval spots of sulphur yellow,
greater wing coverts edged and feathers of the rump tipped with the same. Quills
brownish black, edged on their inner webs wTith yellowish white, and on their
outer webs with sulphur yellow. Middle of the abdomen and ventral region
pale yellow, sides (from the breast to the flanks) and under tail coverts greenish
yellow, all the feathers of which are widely tipped with that color and black at
base. Tail brownish black, bill and feet dark. Female similar to the male, but
with the colors less vivid. Another specimen (female) has many of the^pots on
the upper parts changed to chestnut color, and a trace of the same on the sides.

Hob, — Moonda river, Western Africa, discovered by Mr. P. Belloni Du Chaillu.

Obs.— This handsome species, though apparently properly belonging to this
group of the Bucconince is unusually large. It does not closely resemble any
other with which I am acquainted in any considerable degree, though of the
general appearance of the smaller African species.

This bird is named in honor of its discoverer, Mr. P. Belloni Du Chaillu, an
enterprizing young traveller, who has explored extensive and almost unknown
regions of Western Africa, near the Equator, and whose discoveries in zoological
and geographical science are in a high degree important and interesting. Mr.
Du Chaillu ascertained the existence of three ranges of mountains at a distance
of 150 miles from the coast, in which he traced the river Moonda to its source.
The birds described in the present paper were collected during his journey along
the course of this river. In his collection there are also numerous species hitherto
little known, of which, and of those now described, his ample and interesting notes
have been most kindly placed at my disposal, and will be published at my earliest
leisure.

2. Barbatula fuliginosa, nobis.

Form. — About the size of the preceding. Bill short, straight, wide, first quill
spurious, fifth slightly longest, tail short, legs moderate, toes long. Belong ap-
parently to the genus Gymnobucco, Bonap., and much resembles Gymnobucco calvus
in form and color, but is smaller and has the head covered with feathers, and the
toes much longer.

Dimensions. — Total length (of skin) male, 5f inches, wing3i, tail 2 inches.

Colors. — Head above dull yellow, throat cinereous, all other parts of the plumage
above and below fuliginous brown, some feathers on the abdomen, flanks and
rump obscurely edged with greenish yellow. Quills brown, paler on the inner
webs, tail dark brown, with a tinge of greenish yellow. Bill horn color, legs
dark.

Ilab. — Moonda river, Western Africa. Discovered by Mr. P. Belloni Du Chaillu.

Qbs. — This species, of which Mr. Du Chaillu assures me that his specimens are
adult birds, and of which male, female, and young are in his collection, is very
similar to Gymnobucco calvus, Bonap., which is also in the collection of the
Academy. The head above, however, is not bare as in that species, but fully feather-
ed, and this bird is smaller, though the legs and toes are stronger, and the latter
much longer. The bill is very nearly of the same form as in that species, being
wider vertically and shorter than in other African birds of this group. This

1855.] 325

species and G. calvus probably form a distinct subgenus, but tbe name given to it
by the Prince of Canino is not appropriate so far as relates to our present bird.

3. Diceum Rushi.e, nobis. Mrs. Rush's Warbler.

Form. — Very small, bill slender, curved, first quill spurious, fourth and fifth
longest and nearly equal, tail short, legs and feet rather stout. Plumage of entire
head and breast scule-like and rough to the touch.

Dvmtnsions. — Total length (of skin) male, 3 inches, wing If, tail 1 inch. Female
slightlv smaller.

Colors. — Every feather of the head above, neck, back, throat and breast with
a central line of brown (sienna) and edged with ashy white, tbe brown darkest
and predominating on the head, and palest but much predominating and giving
the prevailing color on the back ; the ashy white predominating on the throat
and breast. Abdomen, rump, and tail coverts above and below pale yellow,
tinged with greenish. Quills brown, edged with white on their inner webs, tail
dark brown, nearly black. Bill with the upper mandible black, under mandible
white at base and tipped with black, tarsi and toes light colored. Inferior coverts
of the wirgs white.

Bab. — Moonda river, Western Africa. Discovered bvMr. P. B. Du Chaillu.

Obs. — This is the most remarkable species in the present collection, and of its
generic relations I am by no means certain, though it appears to be most nearly
allied te the group in which it is at present placed. In its colors, however, it is
quite different from any other known species of this genus, and the scale-like
feathers of the head and breast are quite peculiar.

This bird is dedicated to the lady of James Rush, M.D., of Philadelphia, who,
most ably seconding her distinguished husband in an enlightened encouragement
of men devoted to the sciences and to the arts, has exerted an influence in the
highest degree beneficial to their progress, and promotive of the true interests of
society.

4. ^Egithalus flayifro.ns, nobis.

Form. — Bill straight, pointed, rather long, first quill spurious, third and fourth
longest and very nearly equal, tail rather short, legs long, rather robust.

Dimensions. — Male, total length (of skin) 3J inches, wing 2^, tail l\ inches.

Colors. — Forehead bright yellow, entire plumage of the upper parts olive green
tinged with yellow, lightest on the rump, quills and tail dark brown, the feathers
of both edged with yellowish green on their outer webs. Entire under parts
pale yellow, tinged with green. Inferior wing coverts white, bill and feet light
horn color.

Hub. — Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu.

Obs. — Of the same form and about the size of JE. Smithi, but entirely different
in color, nor does it apparently intimately resemble any known species.

5. Syncopta tincta, nobis.

Form. — Bill rather long, first quill spurious, fourth and fifth longest and very
nearly equal, tail moderate or rather short, legs long. Feathers of the back long
and hair-like.

Dimensions. — Male, (of skin) total length 4 inches, wing 2J, tail If inches.

Colors. — Head above, back and rump light cinereous, scapulars, wing coverts,
and outer edges of quills (especially the secondaries) yellowish green. Quills
and tail light hair brown. Throat, breast and sides light ashy, abdomen white,
tibiae ochre yellow, tinged with green. Edge of wings at the shoulders yellow,
inferior coverts white. Bill dark, tarsi and toes light colored.

Bab.— Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu.

Obs. — The affinities of this genus are to the TimalincB. The present species is
rather smaller than Syncopta brevicaudata, but there is no considerable specific
similarity. It is in both the collections of Mr. Du Chaillu and Dr. MacDowell,
obtained by the latter on St. Paul's river.

6. Sylvia prasixa, nobis. (Genus Chloropeta ?)

Form. — Bill rather strong, upper mandible somewhat curved, wing rather long,

326 [April,

first quill spurious, fourth longest, tail moderate, legs and toes rather long and
robust.

Dimensions. — Male, (of skin) total length 4£ inches, wing 1\, tail If ioches.

Colors. — A line over and behind the eye pale yellowish white, another imme-
diately below it (through and behind the eye) and head above unifoim very dark
olive green. Back, rump, wings and tail dark olive green tinged with yellow,
especially on the rump and outer edges of the secondary quills. Entire under
parts very pale yellowish white, with a tinge of greenish ashy. Edge of the
wing at the shoulder pale yellow, axillaries and under coverts yellowish white,
bill dark, feet lighter.

Hab. — Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu.

Obs. — Remarkable for its uniform dark green color and white superciliary line.
Of the generic relations of this bird I am not confident, but regard it as probably
a Chloropeta.

7. Butalis inpuscatus, nobis.

Form. — Bill wide at base, rather short, wing long, first quill spurious, third
longest, tail moderate, slightly emarginate.

Dimensions. — Total length (of skin) male, 4| inches, wing 3}, tail 2 inches.

Colors. — Entire plumage above fuscous, rather darker on the head, and paler
on the edges of the leathers of the back. Beneath fuscous, the edges of the
feathers paler and slightly tinged with pale rufous on the breast, abdomen and
under tail coverts, and on the throat (the edges of the feathers) with white.
Quills and tail dark fuscous. Bill and feet dark. Female similar to the male
but paler.

Hab. — Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu.

Obs. — This bird appears to be allied to Muscicapa Fraseri, Strickland, but is
much smaller, and is in other respects quite distinct.

8. Butalis epulatus, nobis.

Form.— Small, but very robust, bill moderate, wide at base, with several pairs
of bristles, wit>g rather long, first quill spurious, third and fourth longest and
very nearly equal, tail moderate.

Colors. — Throat and middle of abdomen white, breast and flanks light cinereous.
Entire plumage above cinereous, lighter on the rump and darkest on the head,
quills brownish black, secondaries edged on their outer webs with light ash}7,
tail uniform brownish black, bill and feet dark, under mandible white at its base,
under wing coverts and axillary feathers white.

Hab. — Moonda river, Western Africa. Di- covered by Mr. P. B. Du Chaillu.

Obs. — A small but robust species apparently not nearly related to any other.
Its general form is much as though it had been accustomed to good cheer on the
banks of the river Moonda, or wherever else it may have found sufficient enter-
tainment.

9. Pycnosphrys McCallii, nobis. (Genus Pi/znosphn/s, Strickland in Jard .

Contr. 1849.)

Form. — Small, bill moderate, upper mandible curved, and with numerous pairs
of rather strong bristles at base, which are nearly as long as the bill. Wing
moderate, first quill spurious, fourth and fifth longest and very nearly equal, tail
rather long, legs moderate or rather long. Feathers on the head above some-
what elongated and probably erectile, feathers of the back lengthened.

Dimensions. — Total length, sex unknown, (of skin) 4 inches, wing If, tail If
inches.

Colors. — Head above and tail fine rufous, every feather of the former with a
central line of white, back, rump and wing coverts light cinereous, tinged with
rufous on the rump and darkest on the wing coverts, upper tail coverts rufous.
Throat and breast very pale reddish yellow, abdomen and under tail coverts
white, underwing coverts pale reddish yellow (uniform with the throat). Bill
and foet light colored.

1855.] 327

Hob. — Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu.

Obs. — Another bird, the generic position of which is to us uncertain. After
careful examination, however, it appears most properly belonging as we have
placed it. This species is strongly characterized by the bright rufous of its
head above and tail.

This bird is named in honor of Col. Geo. A. McCall, late Inspector General in
the Army of the United States, in token of respect for hib extensive and varied
acquirements as a naturalist, and of personal friendship.

10. Drymoica Bairdii, nobis.

Form. — Bill rather long, wing short, rounded, first quill short, fifth longest,
tail long, graduated, legs long, rather slender.

Dimensions. — Male, total length (of skin) 5f inches, wing 2£, tail 3 inches.

Colors. — Middle of the abdomen white, entire under parts with regular trans-
verse narrow bands of dark brown, (nearly black) and white. Head above
asby brown, other upper parts dark brownish olive, coverts of the wings and
some of the shorter secondaries tipped with white. Quills hair brown, lighter
on the edges of both webs, tail hair brown, tipped with white, and a rather
obscure subterminal band of dark brown. Under wing coverts, white. Bill
and tarsi dark (nearly black, in skin). Female similar, but slightly smaller,
white space on the middle of the abdomen larger, tarsi lighter colored.

Dab. — Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu.

Obs. — This species differs in colors from any other known to me, and the
transverse bands of the inferior surface of the body are, so far as I know, pecu-
liar to the present bird only of this genu^.

This remarkable bird is dedicated to Professor Spencer F. Baird, of the Smith-
sonian Institution, one of the most eminent American naturalists, as a remem-
brancer of our long continued and pleasant friendship.

11. Laniarius lepidus, nobis.

Form — Bill rather long, wide at base, much compressed towards the end,
which is hooked and conspicuously toothed, first quill nearly spurious, fifth
longest, tail rather long, feathers of the rump long and soft. Tarsi rather long.

Dimensions. — Total length, male (of skin), 9 inches, wing 4J, tail A\ inches.

Colors. — A spot before the eye white, the feathers of which are narrowly
tipped with black. Entire upper parts olive tinged with yellow, especially on
the rump, superior coverts of the wings greenish brown, every feather and the
exposed ends of the secondaries having a terminal spot of greenish yellow and
on their inner webs with pale yellow. Entire under parts of the body ashy
white, darker on the breast. Tibiae, flanks and under tail coverts yellow, the
former tinged with greenish. Tail yellowish olive tinged with yellow, and all
the feathers, except the two in the middle, tipped with pale yellow. Under wiug
coverts yellow. Bill and tarsi dark.

Hub. — Liberia. Rev. Wesley Johnson; St. Paul's river, Dr, MacDowall;
Moonda river, Mr. Du Chaillu.

Obs. — Though this singular species has long been in the possession of the
Academy, I have not found it described. It appears to be somewhat similar to
Laniarius peli, Bonap. (Consp. Av. p.* 360), but not identical, so far as can be
ascertained from the short description as cited. This bird can be easily recog-
nized by the white spots in front of the eye, the feathers of which are erect and
tipped witli black, and by the yellow spots at the tips of the wing coverts and
secondaries.

12. Criniger xaxtiiogaster, nobis.

Form. — Bill rather long, slightly curved, wing with the first quill spurious,
fourth longest, tail rather long. Feathers of the rump somewhat lengthened
and soft.

Dimensions. — Total length (of skin), male, 11 inches, wing 3f. tail 3} inches.

Colors. — Entire upper parts yellowish olive, the yellow more distinct on the
rump. Quills dark brown, edged on their outer webs with olive, and on their

328 [April,

inner webs with greenish yellow. Entire under parts light yellow, tinged with
olive green on the breast and sides, throat slightly mixed with white, and the
shafts of some of the feathers on the neck before white. Tail above dark olive,
beneath greenish yellow. Bill and feet light colored.

Hab. — Moonda river, Western Africa. Discovered by M. P. B. Du Chaillu.

Obs. — Apparently a Criniger, Temminck, and almost exactly resembles in color
Criniger ictericus, Strickland, of India, but is smaller, and otherwise different.
The only specimens that I have ever seen are in the present collection.

13. Tricophorus leuccrus, nobis.

Form.— Bill wide at base, wing with the first quill subspurious, fifth quill
longest, tail moderate, with the feathers broad, tarsus and toes rather short.
Feathers of the rump lengthened and soft.

Dimensions.— Total length (of skin), sex unknown, 7 inches, wing 4, tail 3
inches.

Colors. — Four middle feathers of the tail brownish black, other tail feathers,
(four on each side) white, tinged with yellow on their outer webs and tipped
with brown. Entire upper parts yellowish olive, darker on the head. Quills
dark brown, edged with yellowish green on their outer webs and with pale
ashy white on their inner webs. Entire under parts dark cinereous tinged with
yellowish green, under coverts of the tail yellowish white. Bill and feet dark.

Bab. — St. Paul's river. Discovered by Robert MacDowall, M.D.

Obs. — This is another bird which I have found some difficulty in assigning to
a genus. It can easily be recognised by its white tail feathers, as described
above.

14. Phyllostrophus leucopleurus, nobis.

Form.— Bill moderate first quill short, fourth slightly longest, tail rather long,
tarsi and feet rather long, feathers of the head above somewhat scale-like.

Dimensions.— Total length (of skin) sex unknown, 9} inches, wing 4J, tail 4|-
inches.

Colors. — Entire upper parts brown, with a slight tinge of yellowish on the
back and of ashy on the head. Quills brownish black edged with brown on
their outer webs and with ashy white on their inner webs. Throat and breast
ashy white tinged with brownish green on the breast, where many of the
feathers have central stripes of ashy white. Sides (under the wing) with a
large white space, abdomen and under coverts of the tail white, with a very
pale tinge of yellow. Tail brown, four outer feathers (on each side) widely
tipped with white. Bill and feet dark.

Ilab.— Moonda river, Western Africa. Discovered by M. P. B. Du Chaillu.

Obs. — One specimen only of this fine species is in the collection. It is
strongly characterised by the large white spaces on the sides, which are readily
observed on raising the wing. This bird may be related to Phyllastrephus capen-
.sis or P. senegalensis, of both of which indifferent figures and descriptions have
been given, but of which I have not seen specimens.

Notice of Remarkable Strata containing the remains of Infusoria and Polytha-
lamia in the Tertiary Formation of Monterey , California *

By William P. Blake,

Geologist of the United States Pacific Railroad Survey in California.

When in San Francisco, in June, 1854, 1 received a fragment of a white, porous
earth, resembling chalk ; but which, from its lightness and general characters,

*This notice has been deferred in consequence of the expectation of receiving
from California a full suite of specimens collected at the locality, which
should have arrived by this time. The principal facts concerning the position
and geology of the deposits are now presented, and will be followed by more
important details regarding the chemical composition and organisms of the speci-
mens after they have been received.

1855.] 329

was considered to be infusorial.* A small piece, on being subjected to examina-
tion by the microscope, was found to contain innumerable discs and long cylin-
drical spicule and ring-like organic remains. A portion was then forwarded
to Prof. J. W. Bailey, of West Point, who, in his letter of acknowledgement,
thus remarks : lt The specimen from Monterey is rich in marine diatoms ; the
seive-like discs belong to the genus Cascinodiscus, but there are many other
very beautiful forms present. It is singulai that the deposit contains some species
which have only recently been detected as living species in the Pacific. It has
quite a modern look, and contains many species which could only have grown
in shallow water."

I soon afterwards visited Monterey and examined the deposit. It is about two
miles distant in a south-east direction from the centre of the town, and forms a
portion of a hill which fronts the bay and rises on the east side of the stage-road
to San Francisco. This hill is between 500 and 600 feet high, and it is separated
from the bay by a broad, sandy plain, and a belt of sand-hills along the beach.
Groves of oak trees are found around the base of the hill, but towards its top it
is covered with a dense growth of chamisal,f throughjwhich the outcrop of the
white earth can be seen as a white spot on the hillside from all parts of the
town and the anchorage. On arriving at the locality, however, the white spot
which appeared so limited when viewed from the town, is found to have a length
of about one hundred feet, and a width of from 15 to 40. lt is also seen to ex-
tend in all directions under the vegetation by wrhich it is partly obscured. The
glossy green leaves of the shrubs which grow up about its borders, contrasted
strangely with the white, chalk-like earth, which seemed as little fitted for vege-
tation as a lime-heap. The weathering of the formation has loosened small
blocks and fragments, which lie upon the surface and hide the stratification from
view, so that it at first appears as a homogeneous mass of vast extent ; but on
breaking out some large blocks from a favorable exposure, the lines of stratifica-
tion became evident, and on a closer inspection they were seen to be as numerous
and thin as the leaves of a book.

This out-crop appears to be the principal stratum, and it is near the top of the
hill ; but lower down a succession of strata are found alternating with siliceous
beds, which are peculiarly compact and very finely stratified. Some of these
are excessively hard, and break with a conchoidal fracture like flint or semi-opal.
The whole form a series of parallel strata which are not horizontal, but dip south
of east, or nearly south-easterly, at an inclination of from twenty to thirty de-
grees. The following is the succession of the strata from the upper stratum
downwards to the lowest point examined.

The thicknesses stated are approximations.

thickness, and this is believed to be much less than it in reality is. The under-
lying strata, which are similar in their appearance, are probably equally fossili-
ferous, but this has not been demonstrated by examination. Their thicknesses
were respectively, 1, 12, 2 and 10 feet, which, added to the thickness of the
upper stratum, make a total of seventy-five feet. This is exclusive of the com-
pact siliceous strata, which are presumed to be also fossiliferous. These siliceous
layers are very extraordinary, some of them being like semi-opal in density, and
in the character of their fracture, the surfaces being curved and vitreous, and
the edges sometimes as sharp as glass. Their color varies from white to drab,
or fawn-color, and is sometimes pink ; some specimens resemble ivory or horn
in color and translucency. Silica appears to be the constituent, and it must have
been deposited in an impalpable form. The mineral characters of some of these
strata are like those of specimens of surf-worn boulders that I picked up on
the beach at San Pedro. These consist of silica charged with bitumen, and when
broken present a conchoidal fracture and a resinous appearance. It is expected
that these siliceous specimens will not only be interesting chemical^, but that
they will furnish beautiful objects for the microscope.

On the top of this formation there is a rudely stratified or assorted mass of
boulders and gravel, like the accumulation along a beach. It is, in fact, a layer
of beach-shingle, and it includes, among pebbles of granite and other rocks,
water- worn masses of the compact siliceous rock, probably derived from the sub-
jacent beds. One of these siliceous masses that was dark colored and probably
bituminous, was found to be perforated by boring testacea. This was an unex-
pected and interesting discovery; for, here were masses of rocks of tertiary age
that had been exposed and perforated by marine shells before being broken off,
rounded and worn by the surf among other and harder rocks, and thrown on a
beach by the retiring waters. The beach still remains, and rests exposed on the
very summit of the hill, covering the edges of the strata — a remnant of a for-
mer shore now five hundred feet above the ocean.

This interesting formation, teeming with the skeletons of microscopic organ-
isms appears to overlie and to be conformable with the tertiary strata that
underlie a part of the town of Monterey and extend to and beyond the Mission
of San Carlos. These strata rest upon a porphyritic granite, which forms
the projection of the coast called Point Pinos, and is the bulwark of the bay.

Several quarries have been opened in the sedimentary formation near the
town, and it is seen to consist of regular strata of light-colored argillaceous and
arenaceous material ; the particles being very fine and firmly impacted, so that,
in some places, the strata break with smooth, curved surfaces, and have a semi-
vitreous lustre. A large quantity oi stone has been removed from these quar-
ries and used in the construction of the buildings and walls of the town. The
large Court House built by Walter Colton, and the church erected in 1794, are
constructed of this stone, and the sharp edges and angles which are retained by
the blocks in the walls of the latter show that the material has great durability
and resists decomposition exceedingly well.

When the blocks are freshly broken out from the quarry they are easily hewn
into shape by an axe ; being extremely light and free from coarse sand or
gravel. They harden slightly on exposure, but may be cut away with a knife.
The color is a light buff or yellow, of various shades, passing into fawn color
and drab ; some of the beds are quite dark, being greenish black, or a dark olive
brown. The prevailing color is, however, a light drab or yellow, very similar
to the color of bath brick or lithographic stone. It is not unlike the former in
density, being porous, and, when dry, ic absorbs water with rapidity ; in this
respect and in density, it also resembles biscuit-ware, or the material of the
porous cells of Grove's batteries.

These strata are fossiliferous, and many of the compact layers when split up
into slabs parallel with the fine lines of stratification are found to be covered
with impressions of small bivalve shells, lying thickly together, sometimes one
within the other, as if they had fallen upon the bottom of a quiet sea. The
most abundant shell is a small Td-lina, which Mr. T. A. Conrad has described
for me and named T. coi/gesta. It is also found in similar strata at San Carlos,

1855.] 331

and is there associated with Lutraria Traslii, Conrad, also a new species. Im-
pressions of very small crabs have been fonnd in this rock, and I have also
seen wh^t appeared to be the marks of fucoides on the surfaces of ihe layers.

A stratum of the Monterey formation similar in texture to the stone which is
used for building, but different in color, also contains casts of Tellina congesta
in great numbers. The color of this rock is a dark olive green or brown, but
when it has been weathered the surface is white. When it is dry it is very
light and adheres to the tongue, being very absorbent. Though soft and easily
cut with a knife it is very tough, and gives a ringing sound when struck by a
hammer, like a well baked tile.

In addition to the Tellina and other fossil shells which this rock contains, it
is charged with innumerable and beautiful Polythalamia, (Foraminifera, D'Or-
bigny.) lying in thin layers through the mass and becoming visible in white
lines on the edges of the slabs. They may be seen with the naked eye, but the
assistance of the microscope is required to trace the forms of those that happen
to be exposed. They are very wrhite and perfectly preserved, and are exceed-
ingly beautiful objects for the microscope. It is, however, to be regretted that
the material in which they are preserved is so indurated and resisting that it is
impossible to get them out for study. Every cross fracture of the rock pre-
sents innumerable sections, and occasionally the full form of a shell is visible
on the surface.

The rock has another interesting peculiarity, which must be mentioned — it is
bituminous, and gives off an empyreumatic odor when it is heated before the
blowpipe flame. The specimens which I have are perforated by Petricola cylin-
dracea and other boring shells.

The upper stratum of the formation at the quarries, which is overlaid by the
beach shingle before mentioned, is worn smooth and uneven, as if it had been
subjected to the action of the surf. It has been perforated by Tholadidce., and
their cells still remain. They are large and numerous, but no shell could be
found in them. They are tilled up with fine sea-sand, which indicate that the
shells must have been removed before the surface emerged from the tide. The
cells are in all respects similar to those now being formed and occupied in the
rocks of the beach.

This locality is now at an elevation of about sixty feet above the beach and
one quarter of a mile from it. It presents convincing evidence of the compara-
tively recent elevation of the coast.

The connection between the strata of siliceous infusoria and the strata con-
taining the Polythalamia has not been traced, but it is probable that the two
deposits are conformable, and parts of one great series. If this is so, we may
conclude that the intervening strata are also charged with fossils. The forma-
tion, so far as already known, is a wonderful record of life, and a rich mine of
results for the geologist and palaeontologist.

*Dr. Gambel described a Dipodomys under this name from Los Angeles,
but unfortunately omitted to mention any specific characters. Having re-
ceived specimens from this same locality, clearly referrible to D. philltpsii, I
was forced to consider Dr. Gambel's name as a synonym, his description apply-
ing as well to one as the other. I accordingly, in my notes, gave to the present
species the name of D. gambeli. As Dr. LeConte, in his masterly monograph
of the genus, ha? defined the same species with much precision under Dr. Gam-
bel's name, and is besides satisfied that it is really found at Los Angeles, with
the other, 1 have finally concluded it best to adopt the name of D. agilis, which,
however, is rather that of LeConte than Gambel.

Dr. Leidy stated that he had received from Dr. Nott the bones of the
so-called fossil man, exhibited in New Orleans several years since. The
skeleton was 18 feet in length. There were two molar teeth, each
weighing two pounds, and the fragment of a canine. The bones are
those of the Mastodon. Dr. Leidy described the mode in which the
skeleton was made up.

Dr. Leidy also announced to the Society that the fine skeleton of the
Narwhal, (Monodon monoceros) which had been presented by Dr. Kane
in 1851, had been mounted, and was now in the Museum.

Vice President Bridges in the Chair.

The Committee to which was referred the following paper, by Mr.
Isaac Lea, reported in favor of publication in the Proceedings :

Description of a new Mollusk from the Red Sandstone near Pottsville, Pa.

By Isaac Lea.

A few weeks since Dr. Leidy had the kindness to place in my hands an in-
teresting specimen, consisting of a cast of a bimusculose mollusk which that
gentleman had found last summer at Tumbling Run dam, about a mile south-
east of Pottsville.

The discovery of this small specimen in these Red Sandstones (Formation No.
11 of the Pennsylvania Survey, by Prof. Rogers) is of great importance, as it is
believed to be the first mollusk which has been observed in these Red Sandstones,
underlaying the conglomerate of the coal measures of Schuylkill County, known
as the southern coal field of Pennsylvania, and consequently congenerie with
the Sauropus primcevus , Lea, and Plumites, Rogers.*

The extreme paucity of organic life yet observed in these Red Sandstones ex-
cites the more interest, as the fact of such deficiency of types renders the position
of this formation in the series a matter of doubt in the minds of some geologists.

It is hoped that by patient' research other mollusks may be discovered, and
that, by the palaeontology of this portion of the Palaeozoic rocks, its true position
may be determined.

The specimen is simply a cast of the exterior of the two valves, entirely
flattened out. In its facies it approaches the Cypricardia rhombea, Phill., (Geology
of Yorkshire, pi. 5, f. 10,) from the Mountain Limestone of Northumberland,
England. It is, however, rather more quadrate, and is a much smaller shell. It
has strong affinities to Posidonia, particularly in the strice, and may possibly

coal measures, near Panama, Chatauque County. It is quite oblong, and of much
greater breadth and of a larger size than the species described herein.

belong to that genus which seems to exist first in the Upper Silurian, and to rise
to the superior portion of the Jurassic Formation. It also resembles the Microdcn
ballastriata, Con., (Hamilton Group,) described in the New York Reports, part 4,
page 196, Geology, by James Hall.

As the exterior form only is visible, the diagnosis must necessarily be very
curt. It may be thus characterized until better specimens shall be obtained. I
name it after Dr. Leidy, who first discovered it.

Cypricardia Leidyi.
(Plate IV. The lower figure is magnified ten diameters.)

Shell oblong, round before and truncate behind, very inequilateral, striate;
dorsal and basal margin parallel ; umbonial slope sharply carinate ; anterior
slope with an elevated line from the beak to the basal margin ; striae about
twelve, very regular, and nearly equidistant.

Length 2-20ths, breadth nearly 4-20ths of an inch.

Observations. — This species is remarkable for its outline and striae. The dorsal
and basal margins being parallel, and the posterior margin perpendicularly
truncate, the angk=90D. The striae cover the whole surface of the exterior, and
are bent at an angle of 90° at the umbonial slope. The shell is accompanied
on the specimen with some obscure impressed linear marks of a plant.

Dr. Hallowell read a letter from Mr. Charles J. Gilman, dated

Brunswick, Maine, 1855, inclosing the following communication

from Mr. James E. Powell, a hunter in that State :

" In regard to the moose, I speak of it only as I am acquainted with it in
this State (Maine), other latitudes causing some slight variation in its habits.

When the snows have left the ground entirely bare, which, in the favorite
haunts of the moose, happens about the middle of May, they leave their winter
haunts and approach the marshes, ponds and rivers, where they come to search
for their summer food, consisting of all the various aquatic plants which flourish
in this region. Their favorite food, however, is the water lily and rush, in all
their varieties, and at this season they crop them as soon as they appear, close
to the bottom, frequently holding their heads under water a minute or eighty
seconds, and often wading in water so deep that when they put their heads down
under the surface, to obtain the small lily leaves or to dig up the root of the
plant (which they often eat at this season), before the leaves are plentiful, only
a portion of the back is visible. About this time the females go apart, seeking
the most impenetrable thickets that border on or are near water, and there bring
forth their young ; those of three years old and upwards almost invariably
producing two. Still I have occasionally, but very rarely, seen and known
three at a birth. Those of two years old never produce more thaa one. They
shed their coats of long, rough hair, too, at this period, and are soon covered
with short, smooth, fine hair, of a dark brown color, which, however, soon
becomes a jetty, glossy black on the sides and back and grey on the legs (with
the exception of one variety of the animal, which is of a grey color, and which
is now very scarce here.) As the season advances, the moose frequent the water
still more, and remain in it longer at a time. In May, or early in June, they
seldom stay in it more than half an hour at once, but in July and August they
sometimes remain in the water several hours, and also frequent the waters very
much during the night, especially in hot, dry, sultry weather, or thunder
storms, which they seem particularly to delight in, swimming back and forth,
apparently in a high state of enjoyment. During these visits to the water, the
female, or cow, secretes her young with great care, to protect them from the
ferocity of the old bulls that would destroy them. For this purpose they com-
monly select a very dense clump of large bushes, or a spruce or fir thicket, which,
by its density, prevents the bull from reaching them, on account of his horns,
which generally sprout in April. They grow rapidly, and are very tender and
easily hurt at this time. By September the horns are out of the velvet, and
have acquired hardness, and towards the close of this month the rutting season
commences, and the moose leave the water for two or three weeks and resort to
the mountains. At this period the bulls are frequently very fat (I have killed
them with nearly three inches in thickness of fat on the rump), and are often
very fierce and savage, sometimes even attacking the hunter, but in the course
of a few weeks they become thin and poor, in consequence of their continual
roaming and their many combats, the effects of jealousy. They also neglect
food at this time. At this period the loud bellow of the bull, or the sonorous
'call' of the cow is frequently heard and distinguished by the watchful hunter
at the distance of two or three miles, in the stillness of night. The bulls also
make another noise, which, from its peculiar sound, the hunters call chopping;
it i3 produced by forcibly bringing together and separating the jaws in a pecu-
liar and singular monner, and (as its name implies) resembles the sound of an
axe, used at a great distance. They also emit a variety of strange sounds and
cries. When they return to the water they spend a great deal of time in it for
a week or two, but afterwards they gradually shorten their visits, until the
sharp frosts set in. Still, they occasionally come into it, till ice forms an inch

1855.] 343

thick during the night. Then tbey leave and return to the mountains, where
they select their fall and winter haunts, roaming about and subsisting on the
bark of small trees, which tbey peel or gnaw off, and the twigs of the fir tree
and other woods. When the deep snows fall, they select a spot well adapted to
their wants, and commence to browse and peel more closely. This is called
1 yarding,' and as the snow deepens and crusts form on its surface, they peel and
break down bushes and browse closely, in preference to wallowing through the
snow in search of choicer food. A ' moose yard ' frequently occupies about one
hundred acres, more or less, but the latter few weeks of the season is frequently
spent on an area of ten acres, or less. The old males and females never 'yard '
together, but sometimes young bulls and cows are found occupying the same
1 yard.' Still they are seldom found in close company. Cows and tbeir calves
frequently yard together, the calves remaining with the mother one year. The
oldest buils invariably yard alone, choosing some lonely knoll or mountain
peak, where they reside in utter solitude. Indeed, as age increases, the moose
become more solitary in their habits, avoiding the common resorts of other
moose, and frequenting some lone little pond or stream. The moose of two and
three years old, also, often yard alone, but the males between the ages of three
and ten years are very gregarious. I have known as many as nine in one yard.
When hunted at this time (deep snow) they go off in Indian file, each moose
stepping accurately in the footprints of its predecessor, so that any but an ex-
perienced hunter would scarcely suppose that more than one moose had passed,
when perhaps six or seven had gone in reality. Still, when they are closely
pursued, and the one that is first becomes tired, (in consequence of having to
break the way through the snow,) that one turns out a very little, and (the rest
having passed him) brings up the rear. So they change in rotation, the males
showing the most chivalrous spirit in aiding the females or the weaker ones.
Sometimes, too, they break their order of going in awkwardly passing a tree,
when hard pressed, some going on each side, but instantly falling into line
again when the obstacle is passed. At this season the ' spikehorn,' or two-year-
old bull, is noted as affording the longest and most difficult chase, and the
oldest bulls for making the most gallant fight. In fact, they often refuse to run
at all.

A ' moose-yard ' presents a strange sight to those not familiar with it, with
its broken bushes and peeled trees ; for sometimes, when the snow is very deep
and difficult for them to get through, they break down and browse closely the
tops of young fir trees five or six feet from the ground, and where they are two
or three inches in diameter. They also reach up and peel and browse ten or
twelve feet high above the ground, raising the fore legs and allowing the weight
of the body to rest on the hind ones. Although so fond of browsing the fir,
they never eat the bark of it, yet they seldom kill any other tree, as they gene-
rally peel only one side of those they use for food ; tbey also break down the
bushes in one direction, pulling them towards them ; so that the direction the
moose has taken is known to the hunter by this sign, when he first approaches
a ' yard.' The young fir-trees are killed by the bulls rubbing their heads against
them, instinct teaching them in that manner to apply the balsam of fir (which
possesses great healing: powers) to the sore and tender places caused by the
loosening and falling off of the horns.

The favorite winter food of the moose is the twigs of the fir tree and the bark
of the mountain ash, and of a species of dwarf maple, and the young twigs of
the ' moosewood.'

During the summer the females are often seen accompanied by their two
calves, but in the winter there is seldom more than one calf found with each
cow. From this I infer that the young of the moose are subject to many dan-
gers. The cow gives an abundance of milk, and the growth of the moose is
very rapid for the first three years It possesses immense strength and is capable
of enduring long continued exertion and very great fatigue. It consumes very
little food in proportion to its size, and, during the winter, seldom drinks,
quenching its thirst with snow. Yet it very often chooses its yarding place near

344 [June,

or on some little streamlet, perhaps on account of its favorite maple being most
abundant in such places.

The age of the moose is not great. I have never known but one to at-
tain the age of twenty years ; in fact, it is a rare and uncommon thing to
find one tbat has attained the age of fifteen years. It possesses a quick
ear and very strong, keen scent, and differs from most other wild animals
in regard to its desire to attack a person bearing a torch, or rather the
torch itself. For instance, in bunting on a dark night, in a canoe, on the water,
when in pursuit of deer, &c, a flambeau, or torch, or candle, can be used to
great advantage, the animals being apparently bewildered or fascinated by the
bright, steady light which approaches them so noiselessly and still; but the
moose, as soon as he perceives it, approaches it, quickening his pace as he comes
nearer, till (unless utterly disabled by the deadly rifle shot) he charges full upon
it, destroying the canoe, and frequently injuring its occupant. However, with
the extinction of the torch his fury ceases. The moose is easily tamed, and when
domesticated, exhibits much sagacity, and, if well treated, a very affectionate
disposition. I kept a young one (one year old) a short time, which mani-
fested as much docility and affection as a pet lamb. But when insulted or injured
they are very revengeful and unforgiving. In reference to which I will relate
an anecdote.

The moose above alluded to was a great favorite with a young girl, who used
to visit him several times a day, playing with him and giving him such delicacies
as were most grateful to his epicurean palate (by the way, he acquired a strong
predilection for boiled, mashed potatoes), and the moose alwavs showed the
greatest pleasure when she was present. But one day, in a frolicksome mood,
she bound some gaily colored ribbons in her hair, leaving the ends loose and
fluttering, surmounting the whole by a tall and flaunting plume. Thus attired
she slowly approached the moose, while we stood watching and wondering how
he would recognize her. At length, gently and in perfect silence, she stood
beside the moose, and he slowly and haughtily turned his head, surveying her
strange appearance with the most ineffable contempt. At last, utterly unable
to repress her mirth at the ridiculous scene, she gave way to a fit of loud joyous
merriment. The wonted sound seemed to affect the moose, and he partially
turned his head away, then took another survey of her strange appearance and
his eyes suddenly lit up with a red, savage, fiery light, and he struck her forcibly
with his fore foot, and, had it not been for instant assistance, would probably
have killed her. He never afterwards would permit her to approach him,
showing signs of discontent and anger if she came within ten or twelve rods
of him, and if (when at liberty in the field) he ever saw her he would instantly
rush to attack her. Two or three times, when escaping into the house, she
had not time time to shut the door, and the revengeful beast followed her
into the rooms, to the great detriment of the furniture. We have often heard
of a bull in a crockery shop, but fancy a moose in a parlor. And if I was not
present, no other person could eject him, but he would instantly come at my call
and be obedient and submissive ; and if at any time this strange creature fancied
itself not sufficiently noticed or petted by me, it would utter most piteous cries
until it attracted attention.

The animal in a wild state is very lithe and supple, turning itself about and
bending its form as easily as an ordinary dog, frequently standing in the most
singular postures. It also frequently crawls on its knees, to pass under logs,
&c, and drinks, in very shoal water, in the same position.

I am afraid I have wearied you with my tediousness, but vouch for the facts
above stated, every one of which I know from actual observation and experience."

Notes on the Amar^e of the United States.
By John L. Le Conte, M. D.

Although most of the Amarae found in our country have already been made
known, the labor of determining species from the scattered descriptions of vari-
ous authors is very great. I have therefore thought that it might give some aid
to the final arrangement of the .synonymy of this genus, to bring; together the
diagnoses of those known to me by specimens, as a definite basis would thus be
established for comparison of types of the species in other collections, not ac-
cessible to me ; and even where the names and synonyms adopted by me would
be found faulty, a method of eliminating the errors resulting from differences in
style of descriptions would be avoided.

In the arrangement of the species, nothing can be better than the divisions
proposed by Dr. Zimmermann, although they cannot be admitted as of generic
value. The only alteration I have made is the suppression of Percosia as not
sufficiently distinct from Celia. They are as follows :

1. Thorax ante basin latior.

a. Tibiae posteriores sexus utrinsque intus simplices (Liocnemis Zim.) Sp. 1.

b. Tibiae intermedial maris intus bidentatae (Lirus Zim.) Sp. 2 — 11.

One female found on the north shore of Lake Superior, I formerly considered
this as Curtonotus convexiusculus Steph. (Kiiby, Fauna Bor. Am. 35), but on com-
parison with English specimens it proves entirely different. From that, as from
our other species, it differs by its narrower form, longer elytra, less rounded, but
more sinuate sides of the thorax, and more prominent posterior angles.

One male found at San Diego, California. Narrower than the following
species, and with the thorax more narrowed at the base, and more strongly

by the posterior angles being somewhat less prominent, by the elytra being less
parallel, comparatively shorter and more obtusely rounded at the extremity.

Sitkha ; a specimen received from Baron Chaudoir. Very similar to the pre-
ceding, but with narrower, more parallel, and more convex elytra ; the thorax
is broader and more rounded on the sides, and the basal impressions are less
distinctly bistriate ; the antennae are broken in my specimen, only two points
remaining ; these are rufous, but the others are described as being dark colored :
the feet are entirely black, and the postpectus is punctured.

I have omitted the reference to Mannerheim's description, because he states
that the sides of the thorax are rounded to the base, while in the specimen before
me they are as much sinuated as in A. melanogastrica, and because I have re-
ceived from Mr. Motschulsky, under the same name, a specimen in which the
sides of the thorax are not at all sinuous, and the feet are rufous, as described
by Mannerheim.

Isopleurus hyperborerts\ Lee. Ann. Lye. Nat. Hist. 4, 357.

Lake Superior, Illinois, Wisconsin, Nebraska. The reference of this insect
to Amara hyperborea Dej. (Sp. Gen. 5, 800) is not warranted by the context ;
since that species is compared with A. fodi?i<z, it must be inferred that it
belongs to the preceding division of the genus, in the neighborhood of A. obtusa .
Curtonotus latior Kirby may possibly be identical with the present species, but
tbe bifid tooth of the mentum is insisted on so strongly, as proving that it
belongs to the division with A. co?ivexiusculay &c, that without reference to
the type the synonym cannot be prudently adopted; under these circumstances
I am compelled to propose a new specific name.

Tricena depresses, Lee. Ann. Lye Nat. Hist. 4, 3G5.

Lake Superior and Northern New York. Sufficiently distinct from the pre-
ceding by the thorax being less gradually narrowed in front, by the elytra being
slightly dilated, wider than the thorax and more obtusely rounded at the tip,
with the striae not deeper behind, and finally by the antennae being darker, with
only three joints pale.

The synonym belongs to a dark colored variety, with greenish reflexions.

San Francisco, California, not rare. This species varies somewhat in the punc-
tuation of the striae of the elytra, and the sides of the abdomen ; sometimes the
punctures are quite distinct, while at others they can hardly be seen : the para-
pleurae are, however, always marked with a few punctures.

A single specimen (male) is much narrower than the others, having the pro-
portions of A. angustata, and the thorax is less narrowed anteriorly ; it possibly
indicates a nearly allied species, but in the absence of other specimens, it would
be unsafe to separate it.

minute granulations, as in many species of Harpalus, while those of the male
are shining; in neither sex are any punctures visible.

legs, and base of antennae will distinguish this species. Nevertheless, it seems
to vary in form ; one specimen from Massachusetts, given me by Dr. Harris,
is so much more corpulent than the others and so much more rounded on the
sides of the thorax that I am tempted to consider it as a distinct species.

Middle and Western Siates to the Rocky Mountains; also in Russian Ame-

described, but the third joint of the antennae is not at all carinated : the flatten-
ing of the sides of the thorax is a deceptive c'.iaiacter, and is sometimes hardly
visible. From the following four species it differs by the t'lorax being more

The following European species have been mentioned, probably erroneously,
by Dejean as having been found in the United States : A communis, familiaris,
and similata.

Amara ? grossa Say, Trans. Am. Phil. Soc. 4 430, does not belong to
the genus, but is probably a Nothopus.

Feronia impunctata Say, quoted by Dejean, (Sp. Gen. 3, 469) as synony-

incorrectly named specimen received from Say.

Synopsis of the Hydrophilid;e of the United States.
By John L. Le Conte, M.D.

The species of th;s family seem to have been treated with undeserved neglect,
and in fact there is in their general appearance a sameness, and in the parts of
the body where, specific characters are usually to be seen, a uniformity of structure
which does indeed tend to render the study of them very monotonous : yet on
comparing portions of the body not usually seen, the sternum and adjoining
parts, differences will be found in many cases, which if not associated with the
closest resemblance in form and manner of life would determine the formation
of a large number of genera. Nevertheless the genera, as evidenced by external
character, appear separated by characters of still greater magnitude, as may be
seen from the following scheme of our native genera which is partly arranged
from the excellent labors of Lacordaire (Genres des Coleopteres, 1, 448 and sq.)
I have merely replaced some of the characters by those given by Erichson, and
have suppressed Volvulus and Tropisternus ai being founded on insufficient
characters, and inverted the order of some of the primary divisions.

Abundant in the Middle States, at Lake Superior, and in Nebraska. The under
surface as usual is black, the oral organs, the feet and inflexed margin of the
prothorax are testaceous. Of the markings of the elytra, the most obvious are
an inverted V at the suture, and two small rounded spots each side, all behind
the middle. Sometimes the thorax is almost entirely brassy green, but the in-
flexed pan always retains a testaceous tint. The very small specimens are found
at Lake Superior, and are accompanied by others of the usual size.

Russian America, Baron Chaudoir; one specimen, from Eagle Harbor, Lake
Superior. Easily known by the deeper and more coarsely puuctured striae, and
the unequal elevation of the intermediate spaces of the elytra: the elevation of
the 7th interstice is greater towards the base.

The specimen sent to me as H. consimilis only differs from the type in being
less dark. It may be doubted whether this is different from H. auricollis
Esch. (Entomographien, 43: Mannb. Bull. Mosc. 1843, 260) described from

Le Conte, Agassiz' Lake Superior, 217.

Very abundant at Lake Superior. The third interstice has four elevations, one
of which is at the base, the fifth has three, and the seventh has two besides the
humeral carina : there is also on the ninth interstice a small tubercle near the
tip. These tubercles are arranged so as to form oblique series, which are parallel
with the oblique impression behind the base of the elytra. This species is cer-
tainly allied to, if not identical with H. tuberculatus of Northern Europe, but I
have not had the opportunity of comparing specimens, nor can I find any de-
scription sufficiently precise to warrant their union.

H. angustulus Mannerh. (Bull. Mosc. 1853) from Russian America, is
unknown to me. It seems allied to H. linearis Lee, but the anterior angles of
the thorax aie described as being very much produced and acuminate.

Middle States, not common. This species is the largest I have seen, and is
readily distinguished. The two posterior foveae of the thorax are the basal im-

they are hardly wider than the rows of punctures.

One specimen from Louisiana, Mr. Wapler. Of the same size and form as

elytra.

Head and thorax coarsely and moderately densely punctured, the latter a little
longer than wide, gradually narrowed to the ba3e, sides subsinuate, distinctly
crenulated : disc with three anterior and two posterior foveae, which are large
and moderately deep : at the posterior angles, which are obtuse, are other small
but deep foveae. The elytra are elongate, wider than the thorax, strongly crenato-
striate, with the interstices narrow ; the suture, the 5th, 7th and 9th are elevated,
the three latter interrupted behind the middle, giving the appearance of a lateral
transverse impression ; the fourth is elevated adjacent to the interruption of the
third : on the 3d and 4th interstices near the middle is seen a broad fovea tinged
with purple, and a slight impression is also seen behind the humerus, and yet

One specimen from Louisiana was given me by Dr. Schaum. This species is
closely related to the preceding, but tbe color is darker, and the inequalities of
the elytra are much less apparent, the fifth interstice is elevated about the middle

elevated : the 8th insterstice is slightly foveate at the middle, and there is a faint
impression behind the humerus. /

Middle and Southern States. Closely related to the preceding, but distinguished
by the thorax being less narrowed behind, and the interstices of the elytra being
distinctly wider than the stria?. Dr. Melsheiraer's description reads, " elytra
strongly crenate striate, interstices fine, elevated, second, third and fourth lines
with interruptions at the middle." In comparison with other species these
characters are liable to produce error, and I therefore subjoin a new description.

Elytra wider than the thorax, strongly crenate striate, with the interstices
convex but distinctly wider than the striae ; the suture is slightly elevated, the
fifth elevated posteriorly and interrupted, adjacent to the interruption the fourth
is elevated, the outer ones are also slightly undulated and elevated about the
middle: on the third interstice are three small purple spots, and the interrupted
portion of the sixth is also purple.

Haldeman, Stansbury's Exped. to Great Salt Lake, 375.

Fort Gates, Texas; for the typical specimen collected by Lieut. Haldeman, I am
indebted to his brother, Prof. S. S. Haldeman. The dorsal foveas of the thorax
are larger and the external basal fovea? much smaller than in the next species
to which this related, and the elevations of the elytra are much more distinct.
They are slightly mottled with dark gray; the punctures are very large, and not
closely placed ; the interstices are scarcely wider than the stria? : the suture,
3d, 5th, 7th and 9th interstices are more elevated, the 3d and 5th are interrupted
behind the middle; the posterior part of the 3d is similar in elevation to the
anterior part and extends to the tip, but the fifth rises into a somewhat abrupt
callus ; the fourth interstice adjacent to the interruption is slightly elevated.

Mr. Haldeman has incaatiously stated that this species is allied to H.
scabratns, but its form is quite different, and an attentive examination shows
but little affinity between them.

One specimen found at Eagle Harbor, Lake Superior. The description given
by me is imperfect, on account of the thin margins of the thorax having been
partly destroyed in the only specimen obtained : thus I have stated that the
thorax was sinuous on the sides, while in reality the outline of the disc only is
sinuous ; the lateral margins of the thorax being continuous and regular in their
outline. The discovery of the next specimen, which is precisely similar in

posteriorly; the thorax is destitute of the dorsal lines seen in that species. The
medial channel is wanting in my specimen, but according to the description
given by Maklin, is sometimes visible, though faint.

of the specific name is not obvious. The punctures of the elytra, although
described by him as round, appear to me quadrate, and the intervals are quite
distinctly elevated.

is not mentioned by him, although he states that the longitudinal lateral impres-
sions are almost wanting. Notwithstanding these discrepancies, I must regard
my specimens as authentic, one of them having been received by me from Dr,
Schaum as a type.

San Diego, California, abundant : found also at Sacramento by Messrs. Child
and Wittick. The tip of each elytron is slightlyemarginate, with a smallbut acute
spine at the outer angle of the emargination. The medial vitta of the thorax is
composed of two confluent or closely approximated vittae : at times the vittae
are so dilated that they all become confluent, and the disc of the thorax presents
a large brassy green irregular spot, and the margins are yellow : at other times
the lateral vittae are attenuated anteriorly, so as to appear like subbasal spots
with narrow anterior prolongations. The species is readily known from all
others here described by the very dense and rugous punctuation of the elytra.

One specimen fo».nd by Lieut. Haldeman, at Ringgold Barracks, Texas. A re-
markably beautiful species, in which the elytral striae are not very deep : the
basal one is between the 1st and 2d, nearly one third the length of the elytra :
the interstices are flat, sparsely punctured, with an irregular series of larger
punctures between the 2d and 3d. The spots are scattered ; several are conflu-
ent before the middle near the suture, while those behind the middle form two
angulated lines confluent externally about the Gth interval, with an opposite spot
on the 8th, 9th and 10th: the humeral callus and a neighboring spot are also
black : the spine at the suture is as long as the outer one.

364 [June,

North Carolina, Dr. Zimmermann. The elongate oval body, and deep elytral
striae will distinguish this species, which seems to be variable in character. The
head of the male in my possession is entirely bronzed ; the thorax without any
distinct spots, and the elytra each with four spots, viz : one humeral, one on the
2d and 3d intervals before the middle, one on the same intervals behind the
middle, and the fourth on the 9th interval about the middle : the elytra are
separately prolonged into a very short point at the tip. In the female the head
like the rest of the upper surface is grayish testaceous, with only the occiput
bronzed : the thorax anteriorly has two dark discoidal spots ; the elytra besides
the spots above mentioned have a dark spot on the fifth and sixth intervals about
the middle, and their tips are prolonged conjointly into a moderately long and
acute spine.

Fort G ites and Fredericksburg, Texas ; Lieut. Haldeman. The spots are ar-
ranged as in the second specimen of the preceding species, and the W-shaped
mark is formed by the confluence of the posterior ones ; the humeral dot and
the one on the 9th interval are 'sometimes visible, but are frequently wanting.
It is scarcely necessary to mention that the scutellum. as in other species, is
brassy.

Middle and Southern States, not rare. Varies very much in color, the spots
of the thorax being sometimes reduced to two small points, while at others they
are expanded and confluent, so as to leave only the sides and apical margin tes-
taceous. The elytra are spotted as in B. aculeatus, above described ; the spots
are, however, at times nearly obliterated. What especially distinguishes the
species is the deeper longitudinal impression of the vertex, which gives the ap-
pearance of two very flattened interocular tubercles, as described by Herbst.
Dr. Melsheimer's species is known to me by his kindness in furnishing me with
a typical specimen.

Middle States, abundant; for a typical specimen I owe my acknowledgments
to Dr. Melsheirner. This species is nearly related to several others. From the
preceding it may be known, as already stated, by the small punctures of the
elytra being almost placed in series, by the large punctures of the 3d, 5th and
7th intervals being less conspicuous, by the punctures of the stria? being larger,
and finally by the thorax being less densely punctured.

From B. infuscatus it differs by the stria? of the elytra being strongly impressed,
especially towards the tip:

Middle and Southern States, not rare; specimens from New Orleans were given
me by Dr. Schaum and Col. Motschulsky. This species is a little narrower than
B. s t r i a t u s, but the most reliable difference is found in the elytral striae,
which are fine, and sometimes almost obsolete towards the base.

One specimen, New York. Resembles B. fraternus in having the thorax some-
what densely punctured, but differs by the larger size and more regular arrange-
ment of the punctures of the intervals of the elytra ; the striae are deep, becoming
still deeper towards the tip, and their punctures are smaller and more closely
placed than in B. striatus.

Le Conte, Annals of the Lyceum, Nat. Hist. New York, 5, 211.

Colorado River, California; also found by Dr. i'hos. H. Webb at the Copper-
Mines of the Gila. Also resembles the four preceding; the striae of the eljtra
are fine and well impressed, growing a little deeper behind ; they arc finely punc-
tured, as in B. ordinatus and fraternus, but the interstitial punctuies are much
smaller. The thorax is less narrowed anteriorly, so that the body is less attenu-
ated in front. The spots of the elytra are arranged in three oblique series ; they
are placefl as follows : two on the 2d : three on the 3d ; one on the 4th ; three on
the 5th; one (humeral) on the 6th ; and one on the 9th and 10th. According
to a specimen sent by Mr. Motschulsky, this is B. californicusl of bis catalogue
of Russian ITydrocanthares. The specimen is more shining, and its thorax is
more densely punctured, but is hardly sufficiently different to indicate another
species ; it was found in the valley of the Sacramento.

New Orleans; this interesting discovery we owe to Mr. Wapler. The strie of
the elytra are obliterated at the base, and the inner ones are more so than the
outer ones ; by this means the short basal stria seen between the first and second
in the species above described here becomes wanting. The thorax is broadly
rounded at base, and emarginate at tip ; these curves converge rapidly towards
the sides, which are thereby very much shortened, and the form becomes lunate
with rounded angles ; the punctures are small, but more distinct at the sides
than on the disr*. This species belongs to Volvulus (Brulle,) but the reasons
given by Erichson (Kafer Mark Brand. 204) fur uniting Volvulus with Berosus
are so just, that I have adopted his conclusions.

B. maculo sus Mannerh. Bull. Mosc. 1853, from Russian America, is un-
known to me. It must be allied to B. punctatissimus, but differs in being only
finely and not densely punctured.

Hydrophilus Geoffroy.

In this genus I reunite all those specie3 in which the prosternum is small and
sulcate ; the metasternum produced into a long sharp posterior spine, and the
posterior tarsi compressed and ciliate.

Our species are tolerably numerous, and may be naturally divided as follows :

Stethoxus mbsulcatus Lee. Proc. Acad. Nat. Sc. 7, 221.

New York, Georgia, Texas, Nebraska, California. The anterior tarsi of the
male are more compressed than in the female, the last joint is dilated into a
sharp edged somewhat warped surface, and the claws are very unequal and not
toothed. In the female the claws are equal and* armed beneath with a large
acute tooth. The Californian specimens are scarcely perceptibly less attenuated
at each end, but do not seem sufficiently distioct to be considered a different
species. Col. Motschulsky, to whom I gave specimens for comparison, informs
me that it really is his H. lugubris, but that the short description given by him
is erroneous, having been drawn partly from another very different species from
the Philippine Islands.

The last mentioned synonym was founded on two specimens from the Gila,
brought by Dr. Webb; at first sight they appeared to constitute a separate spe-
cies, the elytra being marked by several shallow but broad grooves; on examin-
ing them again, I am convinced that, although they agree in this character, it
must be regarded as a malformation ; as I find on the sternum and other parts
of the body corrugations which are the result of injury or disease ; and as in
form and in the pubescence of the abdomen they agree with the present species,
it would be proper to place them under it.

New York, Georgia, Nebraska, Texas. Fabricius describes it from South
America, and the identity of his species with ours is therefore doubtful. The
legs vary in color; sometimes they are piceous with yellow margins ; sometimes
they are yellow with only the base of the thighs blackish. The prosternum is
sometimes yellow and sometimes black. The abdomen is entirely pubescent, and
usually appears black ; sometimes a range of small yellow spots is seen each
side near the margin.

California, at San Diego and the Colorado. Differs from the preceding by it3
more regularly elliptical form, acd by the broader yellow margin; that of the
elytra is wider at the base, and there appears triple ; at the mi' die it becomes
narrower, and immediately before the apex is frequently dilated by the addition
of several small linear spots. The prosternum is yellow, and the base of the
thighs black ; the abdomen each side is marked with an indistinct series of yel-
low spots.

Varieties occur in which the sides of the elytra have three or four additional
indistinct yellow lines running from the broader anterior portion of the yellow
margin to the iip.

Hydrocharis Latr.

Although Erichson has placed this genus, which corresponds to Hydrophilus
Leach, and Hydrous Bridle, Mulsant, as a section of the preceding, it appears to
me that the greater size of the prosternum, aad the absence of the metasternal
spine ought to be con&idered with the differences in the mandibles as of generic
value. With regard to the name to be applied to the genus, if admitted, there
is more difficulty. Yet, as the name Hydrophilus, as established by Geoffroy,
plainly belongs to the previous genus, and as Leach, in his anxiety to preserve
traditions even when superseded by actual publication, applied the name Hy-
drous! Linn, to the previous genus, it is obvious that Mr. Brulle acted at least
imprudently, in taking the name last mentioned for a genus so closely allied to
the original Hydrous, as the one now under consideration.

It appears, however, from Agassiz' Xomenclator Zoologicus, that the name
here ad pled was proposed by Latreille in -1825, (Fam. Nat.), while Mr.
Brulle appears to have limited the name Hydrous to this genus in 1834, the date
of his "Histoire Nat. des Insectes," and thus to have been anticipated by La-
treille.

Middle and Southern States. The male is longer and less obtuse in form,
and has the club of the antennae irregular.

Philhydrus Solier.

This genus is not adopted by Ericbson, who considers it as merely a section of
Hydrobius : the very great differrnce however in the length and structure of the
maxillary palpi, as well as the general appearance of the insects, induce me to
believe tbat the separation is natural.

It is otherwise with the genus Helochares (formerly Helophilus) of Mr. Mulsant :
it was separated from Philhydrus by the mesosternum being only very slightly
caiinate, and not furnished with the anterior compressed lamina seen in most
species. Yet in examining the species of both Hydrobius and Philhydrus, I find
such want of uniformity in the sternum, as to convince me tbat characters drawn
from tbat portion of the body must be regarded as specific, or at most sectional
in their value. On. these principles the native species may be thus arranged.

Illinois Mr. Willcox ; Louisiana, Mr. Salle. The prosternum is distinctly
though not strongly carinate : the mesosternum is very faintly elevated in the
middle. The 10th stria of the elytra is distant from the margin, but the interval
is very faintly longitudinally impressed : the margin is narrow and reflexed.

The variety in general appearance resembles Phaleria testacea Say.

New York, Georgia, Lake Superior, Nebraska. The crest of the prosternum,
as in the next two species of this division is acute, and gradually more elevated
towards the tip. Tbis species bears a strong resemblance to P. ochraceus, but
the punctures are finer and less deep ; the prosternal carina will however at once
distinguish it.

San Francisco and San Jose, California. This species has nearly the appear-
ance of P. diffusus of the next division, but besides the differences in the
sternum the sides of the elytra are uniformly declivous, with a very narrow re-
flexed margin, while in all the species of division d. they are slightly concave
with a wider reflexed margin. In one specimen may be seen traces of very in-
distinct striae on the posterior part of the elytra, but in the others no such are
visible.

Nebraska and California : the body is a little narrower in front, and less convex
than in the preceding. The prosteruum is not at all carinate, and the keel of the
mesosternum is horizontal in its iufjrior outline, as in the other specieB < f this
division. The Californian specimens are smaller, a little broader posteriorly, and
a little more convex tban tbose from Nebraska, but I cannot observe any suf-
ficiently definite difference to cause them to be regarded as another species. In
pale specimens the head is blackish with anterior pale spots.

New York, Illinois, Lake Superior, Nebraska. Very closely allied to the pre-
ceding but distinguished by the narrower and regularly elliptical form of body. In
one specimen the anterior spots of the head, and the whole margin of the thorax
are testaceous, the pale border of the elytra is fimbriated posteriorly : the abdomen
is yellowish, with the middle brownish, and the feet are almost entirelv yellowish.
Color, however, is so variable in this genus, that it cannot be taken as character-
istic, and recourse must be had to form and sculpture, which are sufficiently
distinct, in all the species herein noted, to render their recognition a matter of
very small difficulty.

Middle and Southern Stttes and Nebraska: for a type I am indebted to Dr.
Melsheimer. Almost as convex, but not so broad as P. rotuodatus, and readily
kuown by the mesosternum being dilated into a large quadrilateral venic.il plate
in front of the middle coxae.

In answer to some questions regarding the difference between P. cinctus and
limbialis Dr. Melsheimer writes as follows : " the latter is larger, more oval and
less convex than the first ; the colored margins are aLo broader and all ill- other
characters more distinct, but notwithstanding these differences, i now consider
them as different sexes." Say in his description does not mendon the sutural
stria, but I learn from Dr. Melsheimer that it is quite distinct.

372 [June,

Middle and Southern States : the four internal striae of the elytra are gradually
shorter anteriorly: the sutural one is bifid by the confluence of a small scutellar
stria, but with the second is almost entirely obliterated on the anterior fifth of
the elytra. The anterior dilated plate of the mesosternum is not quadrilateral
as in the preceding, but triangular and acute as in Hydrobius, to some species of
which it bears considerable resemblance, but may be distinguished by the long
slender palpi.

In Fauna Bor. Am. (p. 120) Mr. Kirby cites the European P. marginellus and
melanocephalus as occurring in North America : the descriptions however are
not sufficiently characteristic to enable them to be referred with certainty to any
of the species above described to whice they may belong.

New York and Pennsylvania, rare. Not so globose as H. globosus, but
equally convex : the different form of the mesosternal protuberance will at once
distinguish it ; but in addition to that character, the prosternum at tip is armed
with a small acute tubercle.

California, at San Francisco and at the Colorado river. The large punctures

1855.] 373

of the elytra are placed upon the striae, and not scattered on the interstices as
on the two preceding species.

The European H. fuscipes is said by Kirby (Fauna Bor. Am. 119) and by
Mannerheim (Bull. Mosc. 1853) to be found in the northern part of the conti-
nent. The descriptions will apply equally well to the three striate species above
described, yet, on comparison with European specimens, they all seem to me to
be sufficiently distinct. H. insculptus approaches them most nearly, but the
thorax is not so short and is narrowed more obliquely towards the tip.

Lake Superior and Niagara. Though the punctuation of the elytra is as in
Laccobius, and the tibiae appear to have no scattered spines, as in the other
species of this genus, it would scarcely appear natural to separate this as a
distinct genus. The antennae and palpi appear entirely as in the other species.

Hydrophilus subcupreus Say, Journ. Acad. Nat. Sc. 5, 189.

Lyclonotum subcupreum Lee. Agassiz' Lake Superior.

Middle States, Nebraska, Lake Superior, and Colorado River, California; com-
mon. Although in general appearance and sculpture this species resembles
Hydrobius, the antenae have but 8 joints, and are formed as in Laccobiu3 agilis.
The posterior tarsi appear to possess an indistinct row of ciliae on their upper
margin but are comparatively shorter and more slender. The middle and pos-
terior tibiae are furnished with some irregularly scattered spiDes. It is at first
doubtful whether this species should be joined with Laccobius, or with Hydro-
bius (from which it seems to differ only by the number of joints in the antennae),
or whether a separate genus should be established for its reception. From Lac-
cobius however, it differs in the sculpture of the ventral segments of the abdo-
men, and the form of the posterior trochanter, while in these characters it
agrees entirely with Hydrobius.

In the smaller specimens the punctures of the elytra are sometimes less dis-
tinct towards the base. Specimens also occur in which the lateral margin of
the thorax and the tips of the elytra are yellowish.

Cyclonotum Erichson.

San Diego, California, in putrid Opuntia. The antennae are reddish, with the
club dark-colored ; the first joint, as in the next species, is long, being in fact
nearly one-half the length of the entire antenna: Erichson has erroneously de-
scribed (Kafer Mark. 213) it as being short, but the description given by Mul-
sant, (Coleopt. de France, Palpicornes, 148) is correct. The striae of the elytra
are very faint, and merely formed by rows of punctures which are scarcely
larger than the fine punctures which cover the whole upper surface, and they
vanish entirely towards the base of the elytra. The prosternum, though pointed
posteriorly, reaches almost to the mesosternum : the carina is more prominent
anteriorly.

2. C. es tri at u m , rotundato-ovale, convexum, atrum nitidum, punctula-
tum, elytris stria suturali nulla ; prosterno brevissimo baud carinato: palpis an-

Cercyon Leach.

On account of the difference in form of the pro- and mesosternum, Mr. Mul-
sant has separated from this genus three which he names Pelosoma, Megaster-
num (properly Megalosternum) and Cryptopleurum. Erichson has expressed
as his opinion that the characters upon which they were separated are insuffi-
cient, while Lacordaire, in the second volume of his most excellent work on
Genera of Coleoptera, has recombined Pelosoma with Cercyon, but leaves Me-
gasternum and Cryptopleurum distinct.

Having found in America representatives of all these groups, I am inclined to
agree with the views expressed by Lacordaire.

My series of the common species of Cercyon is not sufficiently large to enable
me to investigate the genus in a satisfactory manner ; I will therefore postpone
the description of new species, and the synonymy of those previously described ;
merely making known two species which are remarkable and easily recognized.

I may add as a contribution to future synonymy, that C. mundum Mels. is
C. centrimaculatum, and that C. maculatum Mels. is C. a n a 1 e , both
European species mentioned by Erichson (Kafer Mark Brand.) as found in
America. C. fimbriatum Maniih. described from Sitka, was found by me in
California.

1. C. pubescens, rufo-testaceum, ovale, postice subattenuatum, punctu-

San Diego, in putrid cactus, and also in the valley of the Gila. The lines of
of punctures of the elytra can hardly be seen, but near the margin and behind
the middle are more or less faint traces of striae. The mesosternum is not
wider than long, and the anterior angle is quite sharp. This species belongs to
Pelosoma Muls.

Megalosternum Muls.

One specimen found in York county, Pennsylvania, was given me by Dr.
Melsh^imer. The palpi are precisely as in Cercyon ; the sternum exactly
like the figure given by Mulsant of M. boletophagum : the naked deflexed py-
gidium is an anomaly which 1 have not seen in any species of this family, and
with the pectdiar sculpture seems to indicate an approach to Histeroid genera
like Ontbophilus. Other specimens, when procured, will enable a more full
examination to be made, and will perhaps render necessary the establishment
of a new jienus. The anterior tibiae (as far as I can examine them) do not
appear to be emarginate, as in M. boletophagum. The elevated lines of the
thorax are quite indistinct, except the one nearest the margin, which is entire
and quite obvious.

An allied but much smaller species, without elevated lines on the thorax and

1855.] 375

with the furrows of the elytra less deep and less crenate was found by me
at Panama: in the only specimen left, the pygidium is entirely covered by
the elytra, as in other Cercyons.

between the arms, are soft and covered with short spines ; the interbrachial
plates subrhombic, but not very distinct. The mouth-fissures have each two
large suckers, but no papillae on their sides. Arms suddenly tapering at the
middle ; their superior plates trapezoidal and minutely granulated ; lateral
spines five in each row, the middle ones largest, compressed, with blunt extremi-
ties, longitudinally striated, and denticulated on their edges. Disk dark green-
ish ; arms colored with red and light brown alternately : below white. Taken
in fifteen fathoms among dead corals, on " Groper Shoal," in S. Lat., 20° E. Lon.

Indications of Twelve Species of Fossil Fishes.
By Joseph Leidy, M. D.

1. Myliobates serratus. Based upon a specimen consisting of four median
dental plates, with parts of two others and the first row on each side of lateral
dental plates. The triturating surface of the specimen is quite level, except that
it is slightly depressed along the median line, and slopes off in a concave manner.
The median dental plates are united by sutures slightly convex forward, and
distinctly serrated at their outer part. The first row of lateral dental plates are
nearly hexagons, and they are connected with each other and with the median
plates by distinctly serrated suture.

The attaching surface of the specimens forms two planes inclining to a median,
convex angle.

Breadth of median plates 10 J lines, width antero-posteriorly If lines.

Locality. Discovered by Dr. C. H. Budd, in the Green Sand of Burlington Co.,
New Jersey.

Remarks. The specimen closely resembles a corresponding one characterized
by Agassiz, as Myliobates suturalis.

2. Myliobates rugosus. Based upon a specimen, consisting of four median
dental plates, indicating a large species of the genus, though not so large as the
Myliobates Holmesii, Gibbes, which, however, appears rather to be an Aetobatis,
judging from Dr. Gibbes' figures,* of the same type as the A. eximius. The two
latter might be considered as the representatives of a new genus, in which there
exists a median row of dental plates, and a single row laterally of small tri-
lateral plates. It would be intermediate to Aetob-itis and the true Myliobates, and
might be called Mesobatis. The triturating surface of the specimen of Myliobates

* Journ. Acad. Nat. Sc. 2d s. i. pi. 42, fig. 1.

396 [August,

rugosus is prominently convex and longitudinally wrinkled, especially at the ex-
tremities of the median dental plates. The latter are united by convex suture
directed forward. The attaching surface of the specimen is flat.

Diameter of the median plates transversely 2 inches and 4 lines, antero-pos-
teriorly 4^ to b} lines.

Locali'g. Discovered by Mr. Horner in the Marl of New Egypt, New Jersey.
T. A. Conrad.

3. Myliobates obesus. Based upon a pair of median dental plates of a species
smaller than M. rugosus, and comparatively more convex in its sutures and its
triturating surface.

The estimated transverse diameter of the median plates was about 16 lines,
the antero-posterior diameter is 3^ lines.

Locality. Discovered by Dr. Charles H. Budd, in the Green sand of Burlington
Co., New Jersey.

4. Zygobates ddbids. Based upon numerous specimens of isolated dental
plates. The median dental plates are comparatively wide compared with their
transverse breadth, their triturating surface is convex, and the attaching surface
concave and parallel with the former. The lateral dental plates of the first row
present a corresponding width and breadth to the median plates. Their tritu-
rating surface is convex and slopes off laterally, and their attaching surface is
straight.

Transverse diameter of median plates 6 to 16 lines, antero-posterior 2 to 4J
lines, thickness 1|- to 3 lines. Transverse diameter of lateral plates of the first
row up to 13 lines, antero-posterior up to 4£ lines.

Locality. Discovered by Capt. Bowman, U. S. A., in the sands of Ashley
river, South Carolina. Probably washed from eocene beds.

5. Aetobatis perspicuds. Based upon a specimen consisting of one half of
an isolated dental plate of the upper jaw. Although the fragment is a very small
one, it is very characteristic. The triturating surface is smooth, excepting, how-
ever, the accidental scratches ; and it is perfectly level antero-posteriorly, and
is slightly convex transversely ; and the attaching surface is parallel with the
former. The anterior and posterior margins form the segment of a circle bent
at a very obtuse angle. The outer extremity of the dental plate is abruptly
truncated, and the enamel turns down laterally to the extent of a line. The
antero-external angle forms a projecting heel, and the corresponding posterior
angle presents a concave fossa for the reception of the contiguous heel of the
posterior dental plate.

Estimated breadth of the upper dental series 21 inches, antero-posterior width
cf the dental plate at its middle 4 lines, thickness 4 lines.

Locality. Discovered by Dr. J. L. Burtt in the Green Sand of New Jersey.

6. Aetobatis bximius. Based upon a specimen consisting of one half of four
median dental plates, with a corresponding row of lateral plates. The median
plates are perfectly level on the triturating surface, except at their outer ex-
tremity, where they are abruptly rounded off. The sutures are slightly bow
formed, and of the two sides of the outer extremities that anterior is the longest.
The species has but a single row of lateral plates, which are convex at their
outer border, and are angular within to join two contiguous median plates.

Estimated transverse diameter of the dental series, including the small lateral
plates 23 lines, antero-posterior diameter of the median plates Z\ lines.

Locality. Discovered by Capt. Bowman, U. S. A., in the sands of Ashley
river, S. C. Probably washed from Eocene beds.

7. Odax carolinensis. Based upon numerous specimens, consisting of por-
tions of the jaws and pharyngeal bones, with teeth. External extremities of the
maxillary denticles very distinct from one another, convex, six in number in a
vertical row of 5-£ lines. Pharyngeal bones triangular, with two short equal
sides, and the long side measuring from 6 to 8 lines, densely furnished with teeth
resembling in form the corresponding ones of Pogomas.

Locality. Discovered by Capt. Bowman, U. S. A., in the sands of Ashley
river, South Carolina.

8. Pogonias. Numerous isolated teeth of this genus, of the same form and
size as those of the recent Pogonias chromis, were discovered by Capt. Bowman
with the preceding in the sands of Ashley river.

9. Sphyr^na major. Based upon numerous specimens (more than a hundred)
of isolated crowns of teeth, the smallest of which measures 3 | lines long and 2.]
lines wide at the base, and the longest 8h lines long by 4| lines wide at the base.

Locality. Discovered by Capt. Bowman in the sands of Ashley river, South
Carolina.

16. Enchodus ferox. Sphy/csna, Morton : Syn. Org. Rem. Cret. Group of the
U. S., PI. xii. fig. i. Based upon specimens in the Cabinet of the Academy,
consisting of fragments of the jaws with teeth, which have usually been referred
to the genus Sphyrcena, but to this they do not belong, as the teeth are not in-
serted in sockets, but are implanted by expanding roots co-ossified with the
surface of the jaws, 'lhe specimens consist of an isolated anterior tooth (repre-
sented in Morton's PI. xii. fig. 1), of a portion of the left intermaxillary bone with
the anterior tooth, which measures If inches in length from its base of attachment:
a fragment of the right intermaxillary bone, with the roots of two large leeto.
and a row of small, uncompressed, conical teeth at the outer margiu ; and a
fragment of a palatal bone, with one large conical tooth having trenchant borders.
and the roots of two other teeth.

Locality. Discovered in the Green Sand near Mount Holly, New Jersey. The
teeth of this species are relatively narrower compared with their length, than in
Enchodus Favjasii, Ag., from the Mtestricht beds.

11. Xiphias astiquus. Based upon a specimen consisting of ten and a half
inches of the extremity of the prolonged maxillary bones.

The posterior broken extremity of the specimen is transversely oval in section,
and measures 2 inches in its long diameter and 1 inch in it3 short diameter.
Anteriorly the specimen becomes more cylindrical, and at the anterior broken
end it measures 5 lines in diameter.

Locality. Discovered by Dr. Chas. H. Buc'd, in the Green Sand of Burlingto.i
Co., New Jersey.

12. Diodon vetus. Based upon numerous specimens consisting of water-
rolled jaws with the alveolar and oral teeth.

The internal or oral teeth consist of a conjoined pair of piles, of from 6 to 10
trilateral laminae, measuring from 3}- to 4J lines wide. The outer or alveolar
teeth are composed of small lamellar denticles, of which the margin of 4 or 5
may be counted anteriorly in the space of a line.

Locality. Discovered by Capt. Bowman, U. S. A , in the sands of Ashley river,
S. C.

Descriptions of new species of Astacus from Georgia.

By John Le Conte.

A few years ago there were but three or four species of this genus known to
inhabit the United States ; lately Mr. Girard, in the proceedings of this Society
vol. vi. page 86. has increased the number to eighteen or nineteen ; but one
however is from the South, A. Blandingii. I now add to this number eight more :
two of them from the upper part of the State of Georgia, the rest from the low
country. There are two more species which I have seen, but have not been able
to obtain. What number of species are found in the rivers of the South is not
yet ascertained. All those which I have seen were inhabitants of ditches, ponds
and rivulets of clear water, or formed burrows in the mud of wet ground. Their
extreme similarity renders it difficult to distinguish the species from each other,
and this difficulty will undoubtedly increase as the number of species is multi-
plied. To what extent this number may reach cannot be guessed at ; it appears
however that when these animals come to be more closely studied, this number
will be very great, and the passage of one species into another become almost
imperceptible; so that among Crustaceans we shall have an analogous difficulty
to that which exists among Uniones. Their color is generally lost with their
life, so that it is of little value in the description. All that I have ever seen
were much of the same color, a reddish-brown, inclining to a dark olive. The
shape of the rostrum and of the chelae and the size of the Areola vertebralis, afford
the best characteristic marks. I have never known this last character to vary in
any degree. In the two others there may occur slight differences of develope-
ment, not however so great as to be of any moment. I do not find that any
marks can be definitely pointed out, by which we can distinguish those which
are subterranean from those which are aquatic.

In all the species of this genus which have come under my observation, I have
observed that the following characters are found. The lamina antennalis is
dolabriform, inwardly fringed, outwardly thickened, straight and ending in a
small spine. The dorsum is smooth with transverse rows of punctures. The
carpus has a deep longitudinal impression. The males also have on the second
and third of the small legs a tooth directed inwards, in some species only on the
second.

In drawing up these descriptions it will be observed that I have preserved the
old name of Astacus in preference to the new appellation of Cambarus. The
very slight and not very apparent differences which have been adopted to dis-
tinguish these two genera appear to me of little moment.

On a new species of Gelasimus.

By John Le Conte.

One species only of Gelasimus ha9 long been known as an inhabitant of our
salt marshes. I now offer to the Society, the description of a second species,
found on the sea coast of New Jersey. It seems hitherto to have escaped the no-

1855.] 403

tice of naturalists. Last summer our associate Mr. Ashmead brought some
from Beesley's Point, N. J., and I cannot find any description agreeing with it. All
the other species in the books except one, appear to have been brought from
tropical countries. I have added a detailed description of the G. pugilator or
common species which is said to be found along our whole line of coast, in order
that a comparison may be made between the two. This I have of course placed
first.

Gelasimus pugilator, Bgsc. Carapace smooth, shining, in front sinuous and
three-lobed, the middle lobe tbe largest, bent down, the lateral lobes but slightly
prominent likewise bent down ; margined, the lateral margins ciliate; anterior
exterior angles right. Back impressed as it were with the letter H, a small de-
pressed spot generally paler colored about one fourth of the distance from the
outer edge of the fore part on each side. Lower eye-lid finely serrate, cheeks
and feet except the chelae hairy. Tail strongly ciliate. Tarsi sharp, slightly
curved. Color dark brownish olive, all the feet lighter colored, chelae nearly
white.

Male. — With either the right or left chela very large, inflated, margined, the
inner margin of the palm bifurcate near the extremity. Palm and carpus granu-
late ; brachium with short irregular rows of granules, the immoveable finger
straight deeply grooved from the point to near the centre, with a triple row of
small teeth, and one large one near the middle, the moveable finger curved,
toothed like the moveable one, with sometimes three larger teeth, and slightly
costate : small chela smooth the fingers nearly straight.

Length -65; breadth anteriorly 1 iuch, posteriorly '4. Large chela 1*7,
small 4.

This species which is found on the salt marshes and the edges of creeks of the
sea shore in innumerable quantities, was first described by Bosc in his Histoire
Naturelle des Crustacee3, vol. vi. page 96, and afterwards by Say, in the Jour-
nal of our Society vol. i. page 71. From its being so common and so well
known I omit saying anything on its manners. It was formerly considered
the same as the G. vocans of Brazil or Amboyna. Whether it is so or not,
remains yet to be determined, the descriptions of the South American or Indian
animal which are to be found in the books being so impeifect, that it is impos-
sible to decide the question.

G. 3iim\x. Carapace very finely granulate with a number of small tuber-
cles near the anterior exterior angles, front as in the former species only the
lateral lobes are much wider and more bent down ; margined, the margin very
finely serrate and ciliate on the sides : anterior exterior angle rounded. Back
impressed with the letter H, with an oblique stria running from the lateral lobe
of the front of the carapace on each side to the upright arms of the impressed
letter. Both the eye-lids are bluntly serrate. Cheeks and feet as in G. pugi-
lator, except the latter are paler colored, as is the tail likewise.

Male'. With the right or left chela very large, inflated, outwardly scarcely
margined, inwardly margined as in the former species, but the bifurcation com-
mences lower down. Palm and carpus covered with tubercles, those on the in-
terior edge of the latter forming a kind of crest. Immoveable finger straight
with a double row of blunt teeth, which near the point are separated by an ex-
cavation for the reception of the point of the moveable finger, the middle is fur-
nished with a single larger tooth. The moveable finger is very much curved
with a triple row of blunt teeth, three of which behind the middle and two be-
fore it are larger; at each of the joints there are one or two red spots, brachium
with short irregular rows of small tubercles: tail ciliate speckled with black ;
small chela, and feet like those of G. pugilator.

Female chelae like the small one of the male.

Length 1 inch ; breadth anteriorly 1-5; posteriorly -65. Large chela 2 8 ;
small, -6.

Reddvius pungens. Black, shining, wings opaque. Head a little hairy, antennae
yellowish brown, slightly hairy, first joint shorter than the head, second, fourth
and fifth much longer, subequal, third very small. Thorax slightly margined,
strongly constricted in the middle, the anterior portion rounded and longitudi-
nally sulcate, the posterior portion transverse. First pair of legs hairy on the
under side, as are the thighs also of the second pair, but the tibiae and tarsi of
the hinder legs all over.

Length .8 of an inch. Inhabits Georgia.

This species is remarkable for the intense pain caused by its bite. I do not
know whether it ever willingly plunges its rostrum into any person ; but when,
caught or unskilfully handled, it always stings. In this case the pain is almost
equal to that of the bite of a snake, and the swelling and irritation which result
from it will sometimes last for a week. In very weak and irritable constitutions
it may even prove fatal.

This R pungens too nearly resembles the R. personatus of Europe to be
authoritatively pronounced different. As however I can find no very detailed
description of the European animal, and as it is difficult to suppose that it
would be imported from its native country, and yet be found in the Southern
States, I have concluded to give it provisionally the name v< hich it bears at
the head of this article. Its food consists of flies and other soft insects, which
it catches very adroitly and soon deprives of all their juices.

Conorhinus sanguisuga. Black, head and thorax granulate, neck rather long
projecting. Antennae slender, first joint much shorter than the head, second,
fourth and fifth subequal about the length of the head, tip of the rostrum
brown. Thorax triangular, with a tubercle in front on each side, slightly con-
stricted before the middle, in front with two raised lines diverging backwards,
and most raised in front, margined with red ; scutellura with two raised diverging
lines directed forwards and joined at the base. Wings granulate at the base,
with two triangular red spots on each, one at the base, the other near the middle
on the outside. Abdomen with six red spots on each side, both above and be-
neath.

Length 1 inch. Inhabits Georgia.

This insect, equally with the former, inflicts a most painful wound. It is re-
markable also for sucking the blood of mammals, particularly of children. I
have known its bite followed by very serious consequences, the patient not re-
covering from its effects for nearly a year.

The many relations which we have of spider bites frequently proving fatal,
have no doubt arisen from the stings of these insects or others of the same genera.
When the disease called spider bite is not an anthrax or carbuncle, iUis un-
doubtedly occasioned by the bite of an insect, by no means however of a spider.
Among the many species of Araneidaa which we have in the United States, I
have never seen one capable of inflicting the slightest wound. Ignorant persons
may easily mistake a Cimex for a spider. I have known a physician who sent
to me the fragments of a large ant, which he supposed was a spider, that came
out of his grandchild's head.

On artificially formed Skulls from the Ancient World.

By Prof. A. Retzius, (Stockholm, Sweden).
[Communicated by Prof. Charles D. Meigs.]

Several years ago the eminent anatomist, Professor Joseph Hyrtl, of Vienna,
had the kindness to send me a cast of an artificially formed skull of great interest.
The original, found at Grafenegg, in Austria, has, by its owner, Count August
von Brauner, been considered as having belonged to an individual of the Avari-
an Huns, who lived in the neighborhood from the end of the seventh to the be-
ginning of the eighth century. Of this skull I have given in 1844 a description
in the Proceedings of the Royal Academy of Sciences of Stockholm, which was
:he following year inserted both in HornschucKs Archiv Skandinavischer Bei-
trilge zur Naturgeschichte, and in Muller's Archiv fur Physiologic I showed
there that this skull, which had been considered remarkable for its length,
certainly was extremely high, but on the contrary short, or of the brachiocephalic
form, to which the skulls of the Avarians, as related with those of the Finlanders,
must belong. This opinion gained at the time very little approbation, because
Dr. Tschudi, renowned for his travels and researches in South America, shortly
after with so much certainty declared that the skull in question was of Peruvian
origin, and supposed that it had been brought over from Peru to Austria with
other collections. Tschudi's opinion gained many adherents, and the question
about the custom in the ancient world of forming the head artificially sank for
some time in oblivion. Through a very excellent treatise by Doctor Fiizinger,
in the Transactions of the Imperial Academy in Vienna, it has been shown that
the skull found at Grafenegg must undoubtedly have belonged to an individual
of the ancient inhabitants of the country. He has not only wholly explained al)
important circumstances concerning this skull, but has also got a quite similar
one from Atzgerrsdorf, in south Austria 1\ mile from Vienna. This had been
dug out of the earth in presence of the physician of the place, Milller. This skull,
as well as the original of the one first mentioned, are now at the Imperial anato-
mical museum at Vienna. The author shows the resemblance between these
skulls and tho=e which have been found at Krim and described by Messrs. Rathe
and Charles Meyer. He mentions the account of Hippocrates (de aere aquis et
locis Lib. 1,) about the macrocephali or Scythians in the neighborhood of the
Moetian moor, who had artificially formed skulls. Further he quotes Pcmponius
Mela (de situ orbis Lib. 1. chap. 19), who says that the custom of changing the
form of the head reigned also among the inhabitants of the Bosphorus ; Pliny
the older, who accounts for the macrocephali in the neighborhood of Ceresus in Na-
tolia on the coast of the Black Sea, the Keresum of the present day ; also Sup h anus
Byzantinus (Geographica,) who tells us of macrocephalic Scythians among the
inhabitants of Colchis, now Mingrelia, on the east coast of the Black Sea. He
quotes from Strabo (Lib. II, Chap. 16), the Derbikks on the Caucasus, towards
the Caspian sea, and the Sigyns, Median colonists, who are said to have lived in
the valley of the Danube at the river Taler, as nations who have used to change
the form of the head, so that the forehead was thus put forward. Doctor Fitz-
inger mentions also another circumstance of importance in connexion with the
description of these skulls, namely, a medal of unknown origin, representing the
destruction of the town of Aquileja by Aitila, with Attilas head in profile, with
the same form as the skulls of Avarians before mentioned. The same medal in
gold is preserved in the royal medal cabinet at Stockholm, where the Rep. ha3
had the opportunity to see it, and to agree with Dr. Fiizinger. Beside these
important informations respecting the singularly formed heads of the Avarians,
this excellent treatise contains al o a close examination of the human skulls
found in the forest of Vienna in the Calvarian mountain, which were described in
1830 by Count Rasumowsky in Oken's Isis, as having an extraordinary form,
and which the Rep. in his former treatise did unjustly believe to be of the
same form as the Avarian skulls. Dr. Fiizinger has examined these heads and
has found that they are of the Slavic form. This learned treatise is furnished

406

[September,

with four extremely good illustrations, two of which represent skulls of Avarians
and the other Slavic ones from the mount of Calvaria. A perfect harmony with
the before mentioned skulls of Avarians is shown in a head found in Switzerland,
of which M. Troyon has sent drawings to the Rep.; copies of them are here repre-
sented reduced to a quarter's size.

The original is preserved in M. Troy oris archeologic collections at Bel-air in
the Canton Vaud near Lausanne. The skull was found at the bottom of a tomb
of very high age, no ornaments or tools were in the neighborhood. Of more
than 200 tombs which have been examined by M. Troyon, this was the only
one of that kind.

M. Troyon has on the same occasion given
several informations concerning discoveries
of other skulls of the same singular form at
the village St. Romain in Savoy, in similar
tombs, likewise without ornaments and tools.
These skulls were so fragile that they fell in
pieces shortly after they had been dug out of
theearth. Nevertheless, Dr. Gosse, at Geneva,
has succeeded in preserving the upper part
of one. The Rep. has through the kindness
of Mr. Troyon got the opportunity here to
show a drawing in quarter size.

There is no doubt that these skulls have
belonged to the same nations as the above

1855.] 407

mentioned skulls from Austria that is, from Avarians, who probably accom-
panied Attila's army. In connexion with this it deserves also to be mentioned,
that Professor Duvernoy at Paris has sent to the Rep. a drawing and description
of a high brachycephalic skull of very remote age, which was found in 1849, not
far from the surface of the earth during the digging of a road in the valley of the
Doubs, not far from Mandeuse. Professor Duvernoy is himself of the opinion
that it must have belonged to one of Attila's warriors, because in this neighbor-
hood the ruins of an old Roman town destroyed by Attilais situated. It has ex-
actly the form of a Finlandian skull not pressed. What a consternation did the
deformed skulls of Huanches Indians, which Pentland brought from Titicaca in
Peru, not excite? What a surprise to see the various skulls which were so
changed in form, and were first made known by Morton's work, Crania Ameri-
cana! This absurd and barbarous custom was considered to belong only to the
savage heathens of America. Through the skull found at Grafenegg, attention
has been turned to the question, how far this same barbarous custom has reigned
also in the ancient world ; more and more evidences affirming this opinion have
been found. As is above seen, we have had the proofs of this fact in the ancient
authors from the old and middle ages, without taking notice of them. To the
important dates quoted by Dr. Fitzinger and M. Troy on, the Rep. takes the op-
portunity to add some more. In the excellent historical work byAmedee Thierry,
Altilij of which the Rep. only knows Dr. Edward Burckhardt's translation,' (Attila
Schilderungen aus der Geschichte des fiinften Jahrhunderts, Leipzig, 1852,) is
mentioned, where the author has shown, that the proper Huns were Finlanders
from the Ural and the valley of the Wolga, but that with them were under the
same government, Turks, and probably Mongols, beside later Slaves, etc., and that
Attila himself, and part of his people have been delineated as belonging to the
Kalmuck type. In a note, page 15, about the custom of changing the form of
the head, he has the following : " The image of Attila is more like that of a
Mongol than of a Finlander from the Ural. Besides we know that the Huns
useJ artificial means for giving Mongolian physiognomy to their children ; they
made, namely, the nose flat, with firmly strained linen ribbons, and pressed the
head to make the cheek bones projecting. What could be the reasonable cause
of this barbarous custom, if not the effort to approach a form, which, among the
Huns, was held in greater regard, in a word, the aristocratic race ? The purpose
quoted by the Roman authors, to get the helmet better fixed on the head, is
scarcely credible. It seems more probable, that when the Mongols were masters
of the Huns, the Mongolian physiognomy was the prize attached to aristocratic
distinctions ; they consequently tried to approach this form, and considered it an
honor thus to deform themselves, in order to resemble the reigning nation. This
is most likely the cause of those unnatural deformations which historical writers
so particularly describe." This opinion agrees fully with that which the Rep.
has supposed in his treatise " Phrenology judged from an anatomical point of view,"
and also with Prof. Eschricht " Angaaende Betydningen of Hjerneskallens og hele
Hovedeis Formforskjellighed (Skand. Naturf. SaJlsk. Forhandl.") respecting the same
custom among the American savages. Thus we see more and more traces show-
ing that this absurd custom formerly has been considerably common in the
ancient world, and, after the authority of Thierry, we may suppose, that it
principally and perhaps originally belonged to the Mongols, among whom the-
Rep. believes it hasnow^ceased. Many who are interested in the study of skulls
will s irely be greatly astonished to hear, that this barbarous custom still exists
in one of the most civilized countries of Europe, namely, in France. About this
we have very interesting information in Dr. Foville's "Traite complet de l'anato-
raie, de la physiologie et de la palhologie du systeme nerveux cerebrospinal, le
partie, Ana":omie, Paris, 1844, page 632, art. " Deformation artificielle du crane"
etc. ; et Atlas, PI. 23, figs. 1, 2."

Dr. Foville says namely: "Dans plusieurs parties da la France, on coiffe Ies
nouveaunes de bonnets fixes sur la circonference du crane lui-meme. Tantot
on commence par l'entourer d'un etroit et long triangle de toile, qui decrit
plusieurs tours avant d'etre arrete, et par dessus ce serre-tete ou bandeau on
place un bonnet rond a coulisses, dont les cordons sont serres suivant la _me

408 [September,

circonference que ce serre-tete lui-meme. Cette pratique est tres commune eu
Normandie. Dans d'autres provinces on ne commence pas par entourer la tete
d'un bandeau ; on la couvre d'un bonnet rond, et ce bonnet se trouve ensuite
assujetti par un nombre variable de tours de bande methodiquenient jetes depuis
les bosses frontales jusqu'aux bosses parietales. C'est ainsi qu'on agit a Toulouse
et dans une grande etendue des pays voisins Une constriction circu-
late, suffisante pour fixer la coiffure ne peut manquer de faire ceder la tete si
tendre a cet age. Ce qu'elle perde alors en largeur, elle le gagne en exces de
longueur; et c'est ainsi que se trouvent produits ces cranes allonges et eylin-
droi'des, (voy. pi. 22 et 23, fig. 1), quelquefois meme etrangles dans le milieu
de leur longueur, qu'on rencontre en proportions variables dans presque toutes
les maisons d'alienes de France, mais surtout dans celles des departements ou
la methode adoptee pour la coiffure des enfants implique une constriction circu-
late. On trouve des personnes du Limousin, de Bretagne, du Nord et du Nord-
Est de la France avec une deformation evidente du crane dont la cause ne peut
etre douteuse. ... A Paris, ou se trouvent rassembles des habitants de toutes
les parties de la France, toutes les habitudes de nos provinces se trouvent
importees, et les deformations du crane produites par les coiffures vicieuses ne
sont nullement rares.''

The 23d engraving in Dr. Foville's work shows three side-faces of women whose
skulls are formed very like the Hunish. Dr. Foville has, in quality of chief-
physician at the great asylums for insane in the Department Seine-inferieure and
Oharenton, had occasion to examine the skulls of a great number of country
people. Here he has found several individuals with thus artificially formed
heads. Though he expresses the opinion that the deformity does not disturb the
functions of the brain, he believes that it does not seldom promote disorders
which finally cause mental derangement. This does not agree with Morton's
opinion about this circumstance among the American Indians. It is more
probable that the worthy author here has taken post hoc for propter hoc. He
mentions two different manners of constricting the head. It seems not probable
that this custom is intended for changing the form of the head ; it rather seems
as if it remained unconsciously from the time of Paganism, and will as many
other prejudices, first cease by some particular accident. The inhabitants of
Normandy were Norwegians ; the race which before inhabited the country is
probably not yet extinct. On the contrary we believe that here, as in many other
countries, the ancient population lives beside the more aristocratic conquering
nation. This latter, the Rep. has himself had occasion to observe, keeps still the
true Norman type. Doctor Foville himself, of Normannic family, is a beautiful
proof of this. The Rep. does not believe that the pressing of the head does
derive from the Norwegians. The skulls of fig. 1, 2, tab. 23 of his work, do
not show the least resemblance with the Norwegian dolichocephalic ones ; but
rather seem to be brachycephalic. The skull, tab. 22, is, according to the opinion
of the Rep., of genuine gaulic type, low, long, dolichocephalic, not artificially
formed. It was taken in a churchyard at Paris, and we know nothing about the
person it has belonged to. It is worthy of attention that this custom is common
in Bretagne, the old county Toulouse, and in several places where the Celtic
race is the predominant one, these countries have before been inhabited by Celts
and first by Iberians. In Beam, where the Iberian race is the most numerous, the
constriction of the head is, according to Dr. Foville1 s account, not used. After all
thesp facts have been mentioned, the question naturally arises : Has this
custom arisen by itself separately in the Old and New World, or does it not bear
witness of a communication between the New and Old World ? The Rep. hopes
on some other occasion to return to the question.

titled " Indications of five species, with two new genera of extinct
Fishes." Referred to Mr. Cassin, Dr. Le Conte and Dr. Henderson.

Mr. Cassin announced that M. Duchaillu was about to return to
Western Africa, for the purpose exclusively of geographical explora-
tion, and the collection of objects of Natural History. Arrangements
have been made to secure, for the cabinet of this Society, the collections
of Birds especially, and also of some other objects. Mr. Cassin ex-
plained the general design of the Expedition, which was to pass from
Cape Lopez, 1° S. latitude, towards the supposed source of the Congo
river, with the intention of attempting to reach its source.

M. Duchaillu has already penetrated farther into the interior of this
part of Africa than any other white man. The coast is unknown farther
inland than from twenty to twenty-five miles, except to slavers, there
having been no exploration of that part of Africa. M. Duchaillu had
been on the Rivers Moonda and Mouni, had traced the latter to its
source, and had ascertained the existence of high mountains, probably
a continuation or spur of the Atlas range, and much further south than
is to be found in any published maps.

Another fact ascertained by him, is the existence of a very populous
nation, of marked negro character, known as the Powein Nation, which
he estimates at from five to seven millions. Their country extends
across from the sources of the Moonda, probably to the sources of the
Nile, and the nation is probably that mentioned by Bruce, as occasional-
ly descending the Nile. It is a warlike and cannibal nation, engaged
in agriculture, not wandering, resembling in this respect the Ashantees
and Dahomeys. It displays the highest degree of civilization yet ob-
served among the true negroes, presenting an analogy to the Feejees,
among the Oceanic nations. M. Duchaillu possesses peculiar advantages
as an explorer. He has lived long in the country, is entirely acclimated,
speaks well two of the languages, and understands thoroughly the negro
character. He proposes to proceed merely with convoys of natives
from each tribe successively to the next.

Catalogue of Marine Alg^e, discovered at Beesley's Point during the past summer,

with some remarks thereon.

By Samuel Ashmead.

Beesley's Point is situated in Cape May County, N. J., on the southern side of
the Great Egg-Harbor Bay, about three miles from the ocean. The bay is about
four miles in length, with an average breadth of two miles, when it connects
with the inlet at the Beach. The water (with the exception of the channels) is

1855.] 411

shoal, interspersed with sedge islands, sand-bars, oyster and clam beds. The
main channel, is deep, narrow, and crooked ; and to a person unacquainted
with the course, difficult to navigate.

Connected with the bay, on the south, is a flat called "Bond's-bar," contain-
ing some hundreds of acres, which, on the recess of the tide, is left nearly bare.

A vigorous growth of Zostera marina occupies a large portion of this bar.

A narrow channel half a mile in length, and leading into " Little Bay " on
the south, separates this bar from the main land, which is Beesley's Point.
" Little Bay," when viewed from the main land at high water, presents the
appearance of a lake, a mile in length, and nearly the same in width. The
water is shoal, and when the tide is out, a mud-flat of considerable extent is left
bare.

At the head of Little Bay, is a thoroughfare extending south, parallel with
the coast line, and navigable for boats to Cape Island. This thoroughfare is
frequently branched, forming islands, and sometimes extends into wide bays.
It connects with the sea by various inlets, the most important of which is
Corson's, Townsend's and Hereford, forming narrow islands known as " Beaches/'
and called respectively "Peck's Beach," " Ludlum's Beach" and "Learning's
Beach."

The sea along the sandy coast is shallow, and the action of the breakers vio-
lent, which, together with frequent heavy gales from the north east, render it
peculiarly unfavorable for the growth of marine vegetation. Yet when we explore
the inlets, the thoroughfares, and the land-locked bays with their coves, secure
from the violence of winds and waves, we find them far from being so unprolific
as they might seem. The sandy-mud bottoms of these shallow waters will be
found carpeted with the beautiful membranous expansions of the Viva latisssi?na,
mingling with the elongated fronds of Enteromorpha intestinalis, whilst a luxurious
growth of Zostera marina affords a resting-place for the floating spores of the
gaudy Rhodosperms.

The total absence of rocks, or stones of any kind, (save a few small pebbles
on the southern shore of the Great Egg-Harbor Bay) produces an unceasing de-
mand for a favorable place for the future growth and propagation of species.

Hence, every submerged substance suited to their condition, is immediately
invested not only with Alga, but with Sertularice and various other Zoophytes.

The limited number of the species of marine Algcc at Beesley's Point must be
attributed to the want of a suitable place, or foot-hold for development, as the
climate and the water, it would seem, supply all the other conditions favorable
to their growth.

The following catalogue, embracing five Melanosperms, nineteen Rhodo-
sperms, and six Chlorosperms, are all that I have as yet been able to detect. A
more careful search may probably supply a few more species.

In the classification, and names of the species, I have followed that emi-
nent Algologist, Hon. Win. H. Harvey, in his "Nereis Boreali- Americana,'' pub-
lished by the Smithsonian Institute at Washington.

Series I. MELANOSPERMELE.

Fucus vesiculosus, Linn. Very common between tide marks, on the shores
of the Bays, and the thoroughfares ; not unfrequently attached to sods by a root
penetrating several inches into the soil, throwing off numerous lateral slioots
having the appearance of undeveloped fronds, forming a strong hold-fast, and
affording an interesting illustration of the modification of a discoid root, where
local circumstances are unfavorable to such expansions. It is, however, more
frequently found adhering by a conical disc to mussels, {Modiola plicatula)
which, at high water, unable to resist the buoyancy of the full grown planl with
its inflated vesicles, are, by degrees, wrested from their place of growth and cast
upon the shore to perish, when the Fucus together with other marine plaots are-
carried away by the inhabitants for manure.

Stilophori rhizodes, J. Ag. Rather rare ; on old shells, &c , near low- water
mark. The few specimens which I obtained are fertile, of vigorous growth,
and densely covered with wart-like fructification.

412 [October,

Ectocarpus littoralis, Lyngb. Very abundant in the Bays, on various sub-
merged substances. Also fringing the steep banks of the thoroughfares be-
tween tide marks. Disappearing in July.

Ectocarpus siliculosus, Lyngb. Occurs sparingly on the shores of Little
Bay, on Fucas vesiculosus.

Ectocarpus viridis, Harv. Common in the Bays, on Zostera marina, &c. Dis-
appearing in July.

Series II. RHODOSPERME^E.
Chondria dasyphylla, Ag. Plentiful in Little Bay, and on " Bond's Bar/'
growing in large tufts on the sandy mud, to which it is attached by a fibrous
root.

Chondria Baileyana, Mont. Common with the above.

Polysiphonia Olneyi, Harv. Rare, on Zostera marina in "Little Bay."

Polysiphonia Harveyi, Bailey. Very abundant in the Bays, and on Bond's
Bar ; on Zostera marina.

Polysiphonia variegata, Ag. Very common, on Zostera marina, also at-
tached to the mud by a fibrous root.

Polysiphonia nigrescens, Grev. I collected fine specimens of this most va-
riable plant, in fruit, in the month of May. It occurs in great abundance in Lit-
tle Bay, attached to the bottom by a fibrous root.

Champia parvula, Harv. Plentiful in Little Bay, on Zostera marina. <
Grinnellia Americana, Harv. Of this beautiful plant I only found a soli-
tary perfect specimen. It was growing in the Great Egg-Harbor Bay near the
shore, attached to the bottom by a somewhat fibrous root. The frond consists
of a leaf-like expansion, four inches long, and two inches wide. Several leaf-
lets, in as many stages of development, spring from the base of the midrib,
giving evidence of vitality.

I had previously discovered fragments of this interesting plant, cast ashore
near the inlet, and also in the Great Egg-Harbor Bay, one of which I sent to
Professor Bailey of West Point, who suggested that it was a drift specimen,
probably from the narrows of New York Bay, where it occurs abundantly.
Notwithstanding that these fragments may have been stragglers, I have had suf-
ficient evidence that this species is an inhabitant of Beesley's Point, and there-
fore give it a place in my catalogue.

Gracilaria multipartita, J. Ag. Plentiful, particularly fine on planted
oysters in Little Bay.

Solieria chordalis, J. Ag. Very common on all the shores. There can be
no doubt, but this bushy plant will grow and flourish in the coves of Little
Bay, and other sheltered situations, without a foothold, for I have rarely found
it attached to the bottom.

Chylocladia Baileyana, Harv. Frequent on Zostera marina, Ulva latissima, &c

Spyridia filamentosa, Hnrv. Particularly abundant and vigorous in the
Bays ; where, sheltered from the winds and waves, like the Solieria chordalis, it
will luxuriate without the slightest attachment to the bottom.

Ceramium rubrum, Ag. This plant, in all its perplexing varieties, is found on
Zostera marina, rather abundantly.

Ceramium diaphanum, Roth. Occurs sparingly associated with the above.

Ceramium fastigiatum, Harv. In dense tufts, on Zostera marina, rather rare.

Callithamnion byssoideum, Am. Frequent on Zostera marina, also attached
to old shells in Great Egg-Harbor Bay.

Callithamnion polyspermum, Ag. Rare, on old shells in Great Egg-Harbor
Bay.

Gklidium corneum, var. y. pinnatum, Grev. I obtained two or three speci-
mens of this plant in Little Bay, on old shells, near low-water mark.

id

T close the list of Rhodosperms with some remarks on an interesting plant, for
which, as yet, I have no name. I obtained upwards of twenty specimens of this
Alga during July and August. They were cast ashore near the inlet of Great
Egg Harbor Bay, parasitical on TJlva latissima, Zoster a marina, and Gracilaria
multipartita, associated with Chylocladia Baileyana. I sought diligently for fertile
specimens, but without success.

This plant, in the articulations of the frond, shows a tendency towards Grif-
fithsia setacea, from which, however, it differs greatly in some of its other
characters.

The branching of G. setacea is on the dichotomous model, and the axils are
acute, whilst in this plant the branching is irregular, showing a tendency to
secund ramification, and the axils are obtuse, particularly in the ramuli, where
they are found to be almost horizontally patent, which is sufficient to distinguish
it from G. setacea.

Perhaps one of the most remarkable characters of this Alga is that the ramuli
generally issue from the middle of the internodes, which, according to Harvey,
would exclude it even from the Order Ceramiacece, to which ihe genus Griffithsia
belongs.

Under the natural character of the Order Ceramiacece, Harvey remarks as fol-
lows : "In the simpler species, the frond consists of an articulated filament,
formed of a number of cylindrical cells or articulations, placed end to end. This
filament is either dichotomously or pinnately branched, the branches being similar
to the main stem, and always springing from the upper part of each internode (or
articulation) either from its shoulder, or from a short distance below that point.1'
See Nereis Boreali- Americana, page 206.

These different characters have been made available by Algologists for the
purpose of classification, and if they are to be regarded as of primary conse-
quence, this plant is certainly new to our coast, if not to science.

The following are some of its principal characters, which may serve to dis-
tinguish it, until fertile specimens shall be obtained. Frond terete; tubular;
monosiphonous ; rosy-red ; two to four inches long ; not much thicker than a
human hair; soft but not gelatinous ; does not readily decompose in fresh water,
nor adhere strongly to paper in drying. Conspicuously articulated throughout ;
the lower articulations many times longer than their diameter; internodes more
or less swollen ; nodes consist of narrow pellucid bands, on either side of which
is a ring of deep crimson, gradually fading towards the central region of the
internode.

The branching irregular ; sometimes showing a tendency to secund ramifica-
tion ; branchlets beset at unequal intervals with secund, spindle-shaped ramuli,
half a lioe to four or five lines in length, frequently horizontally patent, generally
issuing from the middle of the internodes, and sometimes much attenuated at the
point of insertion.

Apices furnished with several whorls of exceedingly minute dichotomous hairs,
oaly visible under the microscope.

Series III. CHLOROSPERME.E.

Bryopsis plumosa, Ag. Not common ; attached to old shells and other sub-
merged substances on the shore of Great Egg Harbor Bay.

Cladophora palcata, Harv. Occurs plentiful in Little Bay.

Enteromorpiia compressa, Grev. Very common everywhere ; infesting the
small pebbles on Great Egg Harbor Bay.

Enteromorpiia intestinalis, Link. Abundant in Little Bay, and on Bond's
Bar. Frequently found floating in large quantities in the Bays.

Indications of five sp ties, with two neio genera, of extinct Fishes.

By Joseph Leidy, M. D.

1. Sicarius extinctus, Leidy. — A species of a new genus, most probably of
fishes, but it may be of reptiles. It is founded upon the specimen of a tooth, or
it may be a scale or a spine ; and it consists of two portions. The body has
much the form of the scales of the Manis, but is surrounded at base with a thick
collar marked with close parallel ridges. The breadth of the body in its perfect
condition has been 15 lines ; its depth on the convex side 9 lines, and on the
vertical slightly concave side 11 lines. The root is 10J lines in breadth and
narrow towards the extremity, which is broken off, and it measures on one side
6 lines and on the other 4} lines in length.

The specimen was obtained from a black stratum, belonging to the coal series,
in number 13 of Rogers, at the head of inclined plane No. 3, of the old portage
portion of the Pennsylvania Railroad. It was presented by Townsend Ward,
E3q., to Charles A. Poulson, Esq., from whom Mr. Conrad borrowed it for my
inspection.

2. Edestus vorax, Leidy. — A species of a new genus of fishes, founded on
the fragment of a jaw with portions of four teeth. The fragment of jaw is 3
inches in breadth by 10 lines in thickness at the dental border, and nearly double
that thickness at the opposed border, which is convex. It is composed of four
wedge-like segments excavated at base, so that those posteriorly are inserted into
those anteriorly, and each has a tooth coossified at the narrower border in^the
same plane as the broad surfaces of the specimen. The teeth resemble those of
Charcharodon, and in their perfect condition have been about 2 inches long, and
have had nearly the same breadth at base. They have strongly and coarsely
dentated borders, and are thinly coated with enamel.

In relation to the affinities of the singular fish to which the fragment belonged
and its exact position in the skullf T suspect it to have been a portion of the upper
jaw of a genus allied to Lepidosteus, from the circumstance that the latter, in like
manner, has the upper jaw composed of a number of distinct segments.

The specimen is most probably from the carboniferous series, and it was ob-
tained by "William S. Vaux, Esq., from an itinerant showman, who found it at
Frozen Rock, Arkansas River, 20 miles below Fort Gibson, in the Indian Terri-
tory.

3. Oracanthus vetustus, Leidy. — This species is founded on an ichthyodorulite,
the body of which in its perfect condition has been about 6 inches in length, and
it measures 1\ inches in breadth at base. The broad surfaces and slightly con-
cave border are thickly covered with mamillary tubercles arranged in very
irregular, transverse rows, and unsymmetrically on the two broad sides.

The specimen is from Missouri Territory, and formerly belonged to Mr. Conrad's
collection now in possession of this Academy. Adhering to its base there is a
portion of black shale with a partially imbedded segment of an encrenite stem,
which Mr. Conrad considers as fixing the specimen in the carboniferous series.

4. Pristis curvidens, Leidy. — This species is based on a single tooth 5 inches
long by 8 lines wide at the point of exsertion. The posterior border at its
thickest part is 4J lines, is straight throughout, and only at its outer two-fifths
is slightly depressed. The anterior border is convex ; and the tooth is con-
siderably curved downward.

The specimen was discovered by W. Taylor, Esq., in the Green Sand, near
Pemberton, New Jersey.

5. Pristis ensidens, Leidy. — This species is founded on numerous specimens
of teeth, of which the largest in their perfect condition have been about 1^
inches long by 7 \ lines broad at base. They are straight and have both borders
equally acute and convex.

The specimens were discovered by Capt. Bowman, U. S. A., in the sands of
Ashley River, South Carolina.

Mr. Ilene La Roche Jr., and Dr. Samuel Lewis, of Philadelphia, were
elected Members.

" Notices of some Tape-worms." Referred to Drs. Bridges, J. A.
Meigs and Hallowell.

Dr. J. Aitken Meigs presented for publication, a revised edition of the
Catalogue of Human Crania in the collection of the late Dr. Samuel
George Morton :

Since the death of Dr. Morton, his magnificent collection of Human Crania,
recently increased by the receipt of 40 skulls from various sources, has been
permanently deposited in the Museum of the Academy. Prior to his decease,
Dr. M. had received about 100 crania, in addition to those mentioned in the third
edition of this catalogue. Since 1849, therefore, the collection has been aug-
mented by the addition of 140 skulls.

To complete the catalogue in a uniform manner, these have been carefully
numbered and measured in accordance with the methods recorded in the Crania
Americana, &c. In a portion of these measurements, I was kindly assisted by
our fellow-member, Dr. Thomas J. Turner, of the United States Navy.

The entire collection, numbering 1007 crania, was purchased by 42 gentle-
men, from the executors of Dr. Morton, for the sum of $4000, and by them
generously presented to the Academy.*

The collection occupies 16 cases on the first gallery, on the south side of the
lower room of the Museum. For convenience of study and examination, I
have grouped it according to Race, Family, Tribe, &c, strictly adhering, however,
to the classification of Dr. Morton. It will be seen, also, that the same arrange-
ment has been adopted in this edition of the catalogue, so that it is an exact re-
presentation of the collection as it stands upon the shelves. While the old
numbering has been carefully preserved for the sake of reference to the various
published descriptions of Dr. Morton, new numbers have been added to desig-
nate the position of any skuli in the natural division or sub-division to which it
belongs.

The crania are distributed as follows :

Extensive and unique as is this collection, it is, nevertheless, still too limited
to justify any positive and comprehensive conclusions concerning the great
fundamental problems of Ethnology. That it will be capable, wheu sufficiently
extended, of throwing much lght upon these obscure and unsettled questions, is
amply attested by the scientific publications of Dr. Morton. It is earnestly hoped,
therefore, that this magnificent nucleus, the result of much pecuniary sacrifice
and many years of enthusiastic labor on the part of its late illustrious owner
aad founder, will not be Deglected ; but that its efficiency will be increased, and
the objects for which it was gathered together attained by contributions from
all who may be interested in the advancement of this youngest, most intricate
and most important of the sciences.

The Norwegians and Danes of the Scandinavian race ; the Bas-Bretons ; the
Celtic Scotch, Welsh, French, Spanish and Portuguese; the Ancient and Modern
Greeks: the Magyar people ; the Great Tartar and" Scythic hordes; the entire
Basque Family, and many other races, are without a single representative in the
collection. Of the Polar and Tchudic Families it contains but 4, and £ skulls
respectively; while the ancient Romans and their descendants, the modern
Transteverini beyond the Tibeu< the great Sclavic race and the Berber tribes
are each renresented by but one skull.

These deficiencies — and many others could be particularized — are recorded in
the hope that the attention of the scientific community being directed to them,
they will sooner or later, be supplied.

On motion of Mr. Lea, it was ordered that a set of the Proceedings,
as far as published, be presented to Prince Charles Bonaparte.

On motion of Mr. Hanson, it was resolved that an invitation be ex-
tended to the Educational Convention about to meet in this city, to
visit the Museum of the Academy.

Descriptive Catalogue of the Ranina of the United Slates.
By John Le Conte.

On account of the numerous errors which have been introduced into that pait
of the Heruetology of our country, which treats of the froes and allied animals,
1 have been induced in this short memoir, to reduce sach as I ba\e been able to
obtain, to some better order. I offer but a descriptive catalogue. To this are
joined all the synonyms which I have been able to collect from works which
could be consulted in this city.

Before I begin, it is necessary to observe that all the Ranina which I have ever
seen, have more or less the power of changing color at will. The character of
color therefore, of so much moment in the description of many other animals, is
here of very little value; for none of the marks dependant on it are constant.
In consequence, it requires numerous specimens, living subjects and locg study
to produce any description that approaches perfection.

How far I have succeeded in my attempt remains to be seen. I have been
long and sedulously engaged in my researches. Every description has been
made from living specimens. The many strange errors and misnomeis pointed
out will perhaps appear at first sight extraordinary and not worthy of belief;
but it is to be hoped that the reasoning which has led me to differ so much from
others, will produce the same effect upon the minds of my readers as it has upon
mine.

Add to the descriptions already given, a short raised line runs from the back
of the orbit, to the tympanum and is curved down behind it. Body above finely
granulate, more distinctly at the base of the jaws. Color above olive green and
olive brown of every shade, irregularly spotted and blotched with dusky, or
uniform brownish dusky without any visible variegation except on the fore part
of the head, where there iS in all an inclination to green ; in some few the whole
body above is green. A deep depression under the nostrils. Beneath white or
yellowish white, sometimes without spots or spotted with dusky only on the
chin, sometimes spotted or blotched all over, or again dusky or black spotted and
varied with white.

Length from nose to the tip of the toes 20 inches.

Inhabits from oce end of the country to the other.

R. nigrescexs Agassiz. Agas. Lake Superior p. 879.

Above very rough with numerous warts, dusky, blackish brown or dark brown,
more or less distincly spotted with darker, the spots frequently angular ; a
longitudinal cutaneous fold runs on each side of the back from the orbits to the
vent. Bo<3y beneath punctate, whitish, very much varied on the chin with black,
sides slightly spotted with white : the under and hind part of the thighs spotted
or sometimes varied with black, the under side of the tibia? and feet are likewise
yellowish with some few spots of black.

Length 2.5 in., arm 1.9 in., leg 3.9.

Inhabits Lake Superior, particularly on the north side.

This species has by some been considered as a variety of the R. fontinalis, to

424 [December,

which species it bears only a remote resemblance. The illustrious naturalist to
whom we owe the first description of this animal was not so ignorant as to con-
found the two together.

A glandulous raised line always extends from the orbit to the sacral promi-
nence. The color varies, being ashy grey, greyish or blackish brown, olive,
yellowish green, rarely brown with a bronze reflection, sometimes without spots,
most frequently spotted with dark brown or dusky, particularly on the sides,
which are always lighter colored than the back. Beneath white or white spotted
or varied with dusky or brown.

Inhabits the Northern States in springs or rivulets of cold water. In the
southern parts of our country the water is doubtless too warm for its existence.

Above smooth, with, some scattered warts or small tubercles either round or
oblong, sometimes uniting so as to form four raised lines the anterior abbreviated
both before and behind, the^posterior only before, but both tubercles and lines
depending for their appearance on the will of the animal. Behind the eyes are
sometimes observed some large punctures. Color green, brownish green, brown
of various degrees of intensity, reddish and dusky, varying to all these at the
will of the animal ; when brown they have frequently a metallic gloss. The
upper lip and tympanum are often golden. When found in a state of torpidity
they are frequently almost black. There is a raised whitish line extending from
under the eye to the insertion of the fore leg, and we never fail to find a raised
cutaneous fold or line of white or yellowish extending from the orbit to the hind
part of the body ; this together with the spots on the sides and back, form the
proper characteristics of this species, yet I have one before me that has but five
spots on the back, three on one side and two on the other with none on the sides.
The lower part of the sides of this near the groin are bluish. This species has
a vocal vesicle on the side of each jaw like the R. esculenta.

I have restored to this speeies its original name of pipiens. Kalm has some
how or other the credit of giving to it the name of halecina, upon what authority
I cannot find, neither can I see how the name fits. The word halec in Latin
signified a kind of sauce apparently like that we now call anchovy sauce.
Afterwards it came to mean any kind of small and cheap fish, by no means how-
ever either herring or shad, both of which must have been unknown to the
Romans before the conquest of Gaul. How the name was taken from this species
and given to the bull frog it would be difficult to discover. No one who knew
any thing of the two animals, would confound the soft peeping sound of a
chicken with the loud roaring of a bull.

The hind part of the thighs is always yellow spotted with black. It is re-
markable for its strong and disagreeable odor. Much resembles the preceding,
but is distinguished at once by the two raised lines on the back being wanting;
these never fail in the R. pipiens. It sometimes has the black spots on the top
of the back connected into two longitudinal bands.

R. clamator. R clamata Daudin 1. c. p. 54. R. clamitans Merrem. p. 176.

Above smooth, with a few scattered warts, dark olive, cinereous or dark green,
with a few irregular black spots, and frequently with a darker line extending
from the orbits to the insertion of the hind legs. Beneath smooth white, more
or less varied with du3ky. Upper eyelid smooth, tympan brown, vomerian teeth
small, the two clusters nearly joined together. Arms and legs barred with dusky,
fingers a little dilated at the tips, the first equal to or longer than the second ana

perfectly free, that is to say without any web ; between the second and third and
third and fourth, there is a slight appearance of palrnation or a webbed membrane.
The webs of the toes do not reach to their points : the second toe is one third
longer than any of the others, and is naked for a greater length.

Length 1.8 in., arms 1.1 in., legs 2.65 in.

This is the true H. clamator of Bosc, (not clamata which is a misreading of
Mr. Bosc'a name); this name has been given by Dr. Holbrook to a species which
I have never seen.

R. cokspersa.

Head punctured and wrinkled in a daedal manner. Body above smooth or
warty at the will of the animal, sometimes these warts being so arranged as to
resemble a cutaneous, fold on the sides of the back. Beneath white, sha-
greened or very finely granulate. Color above green or greenish cinereous,
or cinereous sometimes varied on the greener jaws and on the sides with white.
Top of the back with an infinity of small dots of paler, and marked with nume-
rous small, round, irregularly scattered spots of dusky, which are however some-
times nearly evanescent. Chin and throat frequently tesselate with dusky.
Arms brownish spotted with dusky. Legs above brownish, varied with darker ;
hind part of the thighs warty, dirty white varied with dark brown, or pale brown
varied with darker, beneath spotted with brown, tibia above a little warty, almost
always with a few transverse bars of darker, beneath pale brown, third and
fourth toes much longer in proportion than in other species, toes not dilated at
the tips.

Length 1.8 in., arm and hand 1 in., leg 3 in., thigh 1.6 in., tibia and foot .94,
tympanum .15.

Inhabits Pennsylvania in ponds and ditches.

Individuals are found which at times have the warts on the back arranged in
such a manner as to simulate a cutaneous fold ; beneath this there is sometimes
likewise a short line of the same kind.

A young one of this species which I kept for a long time in a glass jar along
with many others, was able to climb up the vessel in which he was imprisoned
and to support himself there as well as a Hyla would have been able to do.

It has been thought by some that this was nothing more than a young bull-
frog. But I have them not an inch in length, when the larva of the bull-frog
before it loses its tail is frequently three inches long in the body.

This species has sometimes the dark baron the head scarcely distinguishable,
in others it is entirely wanting ; it resembles the Rana temporaria of Europe
very much, and requires a rigid examination to determine that it is not the
same. It does not inhabit the Southern States at least in the lower country.

R. CAPITO.

Above very rough, dark grey or slate-color speckled with black with six
rows of roundish spots on the back ; sides speckled and irregularly marked
with spots of the same form and color ; from the orbits to beyond the middle
of the body runs a broad raised line or cutaneous fold ; and another from
the corner of the mouth to the insertion of the arm. Beneath smooth, yellowish
white, speckled, spotted and varied with dusky ; top of the head coarsely punc-
tured, back and side3 tuberculous. Head very large, broad and blunt, a deep
concavity between the nostrils and the eyes. Irids golden mixed with black.
Tympanum of the color of the body. Lower jaw with a small protuberance or
point resembling a tooth. Arms and legs above grey, speckled and barred with
black ; beneath yellowish spotted and varied with dusky, the yellowish color
more decided at the axillae and groins. Hind part of the thighs granulate. Fingera
slightly palmate at the base, the first longer than the second. The second toe
twice a3 long as the first.

Length 4-2 in., width of the head at the corners of the mouth 1-5 in., arm 1-87,
leg 4-,75, thigh 1-1 in., tibia 1-45, foot 2 2.

Inhabits Georgia in the ditches of the rice-fields. (Plate V.)

TELMATOBIUS Wiegmann.

T. lentiginosds. Bufo lentiginosus, Shaw's Zool. iii. p. 173 pi. 3. Catesbj
ii pi. 69.

Above more or less granulate with small scattered warts, cinereous or dark
slate color, speckled all over with whitish or pale brownish grey, and with
brown or dusky ; beneath whitish, spotted and varied with dusky, particularly
on the throat and under side of the legs. Head small, vertex plane ; irids gold-
en ; tympanum small, scarcely visible from its color. Arms of the color of
of the body, spotted more especially behind, fingers slightly webbed, the first
much shorter than the second. Legs obscurely barred with darker, feet fully
palmate.

Length 2-25, width of head -7, length of the same arm 1-5, leg 3-44, thigh -9,
tibia 1-04, foot 1-5.

Inhabits Georgia.

This animal, with considerable resemblance to a toad, is nevertheless a perfect
frog. It wants the vomerine teeth which are always found in the genus Rana.
Whether the fact of its wanting the small and imperfect vomerine teeth should
make us consider the Telmatobius as distinct from Rana, is a Question 1 shall
not take upon me here to decide ; it is enough to say, that the present eagerness
for the erection of new genera is fast degrading Natural Science into a system
of empirical uncertainty. Of its mode of life I know nothing; it was found on a
road bordered on each side by a deep ditch. Mr. Cate^by, who has an excellent
figure of it, calls it the land frog.

Body above more or less papillous, some of the papillae joined together so as
to form narrow oblong abbreviated lines. Chin and throat smooth, abdomen
and inner and hind part of the thighs, cancellately reticulate. The color above
is dark brown, brownish dusky, reddish brown, cinereous or dull green with
sometimes some very indistict spots of darker or of dusky. The triangular spot
on the vertex is often evanescent as is likewise the vertebral line of paler, or
green or reddish. The white line bounding the black spot from the orbits is
frequently wanting as is also the spot itself, as well as the one from the arm
along the side. Upper lip with sometimes three white perpendicular bars.
Throat and breast often varied with dusky. Tympanum rather indistinct. In
one specimen the color was brown with a golden gloss.

Length 1-4, head "45, arm J8, leg 2'8 in., thigh *75, tibia -85, foot 1*2 in.

Found in immense numbers in every piece of water in the Southern States,
and teas a few years ago commonly known by the name of Savannah Cricket.

Body above with small warts of different forms and irregular disposition,
which are frequently of a yellowish brown color. Color above obscure green or
olivaceous, dotted all over with extremely minute points of black, a short oblong
and oblique dark brown or black spot, often with a white line below it, proceeds
from the orbit to the insertion of the arm, another of the same oblong form and
oblique direction formed from the juxtaposition of very small specks of black,
runs from near the axilla half way down the side, and a third one farther behind
reaches almost to the groin, all these however vary in form, and the third one is
frequently evanescent. Lips generally whitish spotted with black, chin and
throat granulate sometimes yellow, most frequently white and often speckled with
dusky, top of the nose with transverse wrinkles, tympanum small and indistinct,
of the color of the body. Body beneath white, with a fold on the breast betv< een
the arms. Abdomen rugoso-granulate, punctate. Legs beneath grey, thighs
on the under and hinder parts granulate with white, one of the granules on each
side of the anus larger and very conspicuous, above these is an angular darker

1855.] 427

spot. Arms and legs barred or spotted with darker or dusky, thighs with one
or two darker spots, tibia a little varied in the same manner. Very much resem-
bles the preceding but the head is shorter and blunter, the body likewise is not as
slender or as graceful in form as in A. gryllus, having a considerable resem-
blance to a toad. Varies extremely in color and in other marks. The only un-
varying marks which I have been able to discover are the warts on the back, the
dusky line from the axilla on the side (which sometimes almost vanishes) the
darker angular spot above the anus (which at times is scarcely perceptible) and
the while granules on the hinder and under parts of the thighs. They are found
of a green color with a reddish line along the middle of the back, and olivaceous
with a red or green vertebral line, in the majority of specimens however this
line is entirely wanting. In some the warts on the back are few in number, and
the lower ones on each side coalesce into a line resembling a cutaneous fold. In
others a few dark spots of greater or less size are seen on the back, and there is
on the head a large triangular spot of dusky, the base of which is placed be-
tween the orbits, the apex pointing backwards often to be only traced by three
narrow lines forming a triangle frequently reduced to one transverse bar, and
again being sometimes entirely wanting. Theie are likewise in some a few
large oblong spots of cinereous dusky ou the back, which are so placed as to
form a recurved vitta on each side of the vertebral column, they are however
sometimes not joined together and then may be said to be scattered irregularly.
The upper lip is sometimes white varied with black, sometimes entirely white,
of which c dor is also the lower lip, almost always dotted with black. The black
spot from the orbit to the arm is often wanting and its place occupied by the
enlarged inferior white line. In many individuals the spot from the axilla is the
only one visible on the side. The fingers in all are slightly bullated at the ex-
tremity, which gives it the faculty of supporting itself on smooth perpendicular
surfaces.

Whether all the variations above mentioned are permanent in the individuals
where they have been observed, or depend upon the will of the animal, I have
not been able to determine precisely. In many instances however, they are the
voluntary changes which for some unknown reasons this creature chooses to
make in its appearance.

Length 1-2 in., head -3, arm -6, leg 1-7, thigh -4, tibia -5, foot -6.

Inhabits the Northern and Middle States.

Body elongated rather narrow, above with numerous small warts. Color
above dark slate, with more or less of oblong, oval or round sometimes very
numerous black spots, which often form stripes. Upper lip white, which color
often extends to the insertion of the arm. Irids golden. Tympanum distinct,
black or of the color of the body. A broad black band extends from the nose
through the eyes and along the sides to beyond the middle of the body. Beneath
whitish, sometimes tinged with yellow with a few black spots irregularly assem-
bled in groups, cancellately reticulate (in dead specimens appearing granulate)
arms and legs spotted and barred with black ; thighs and tibiae granulated, more
or less covered with small warts. A very slight scarcely perceptible web between
the second and third and between the third and fourth toes, the fourth and fifih
are closely united at the base. Fingers and toes with small dilations at then
tips. Chin often dusky.

Inhabits Georgia and S. Carolina in ditches and ponds.

This species has been placed by Dr. Holbrook in the genus Cystignathus, to
which it cannot possi ly be referred, as it has the vocal vesicle under' the chin
and not at the corners of the mouth. M. Dumeril has called it an Acris. Thai
genus has the toes properly and strongly webbed.

C. ornatus. Cystignathus ornatus Holbrook 1. c. pi. 25.

Body short and broad. Above smooth, pale brown or dove or slate color,
with numerous specks of black. Lips whitish, yellowish or flesh color. Irids
golden. Tympanum small, black, distinct. Top of the head with a large, ir-
regular, triangular, dusky spot, the base of which lies between the eyes, and the
apex points backward, this with a long stripe of the same color on each side of
the vertebral column is sometimes very distinct, at others not visible. A black
vitta extends from the point of the nose through the eye and tympanum to near
the insertion of the arm, ana is sometimes continued on until it joins another
which runs along the sides to the middle of the body ; there are one or two
spots of the same color towards the hind part of the body, frequently however
wanting ; when present all these black maiks are bordered by yellow or white.
Beneath except on the throat cancellately reticulate, white or yellowish with
numerous black specks assembled in irregular groups. Legs above with trans-
verse bands of darker or dusky, thighs behind granulate and often spotted with
yellow ; there is generally a black spot on the outer part of the shoulder. The
tongue in this species is much rounder than in the preceding, it is also more
slightly emarginate and less narrowed at the base.

Length 1.3 in., leg 1.8, tibia and foot 1.2.

Inhabits Georgia, very common in the pine barren ponds.

Body very broad and blunt, above covered with small warts ; beneath every
where granulate, the granules on the throat and chin are so Email, that these
parts appear almost smooth, tibia beneath reticulate. The color above varies at
will from pale brown to different shades of ash and to green, with a few irre-
gular spots or blotches, variable both in color and in form, which at times are
so arranged as to assume the appearance of an oblique angled cross ; there are
also numerous specks of black on different parts of the body. Beneath the
color is white, the inner and hinder sides of the thighs are of a deep yellow or
orange color, the under side with that of the tibia deep flesh color, both of them
reticulate with black.

Inhabits from New York to the lower and warmer parts of Georgia, where
however it is very rare.

This animal is the analogue of the Hyla arborea of Europe.

Body rather narrow and elongated. Varies in being above of various shades
of green sometimes nearly black, the green color however being by far the most
common, the other marks are constant. The line on the sides is either yellow
or silvery. In the spring it is found in rice-fields in astonishing quantities. Is
commonly known by the name of the bell-frog, its notes resembling the sound
of small bells. It is frequently called the fried bacon frog, as its voice seems to
some ears to repeat those words. Laurenti considers it as a variety of Hyla arborea
which he calls viridis, although it had borne the former name for many years
before he wrote his synopsis. Our American animal has but little resemblance
to the European, especially in form.

The darker marks on the head and back are sometimes evanescent, but the
yellow spots on the hind part of the thighs are always more or less distinctly
visible. The chin is cancellately reticulate, sometimes speckled with dusky
sometimes altogether of that color. The color of the body above varies at the
will of the animal.

1855.] 429

It is wrong in Dumeril and Bibron to say that this species is a variety of H.
squirella. In shape and size the difference is most considerable. The latter
animal during the warm season is always to be met with about houses, the H.
femoralis never. Besides, their notes are entirely different.

H. squirella. H. squirella Daudin, 1. c. p. 18. Calamita squirella Merrem.

Color varying at the will of the animal from green to brown of different
degrees of intensity, spotted and speckled irregularly with darker or dusky and
sometimes with paler, often however of a uniform color. A darker line extends
from the nostrils to the eyes and through them to the insertion of the arm (this
is sometimes evanescent) ; beneath this darker line extends a white one which
reaches nearly to the groin ; sometimes interrupted or broken into three or four
parts. The dark line on the vertex between the eyes never fails entirely, al-
though it is sometimes reduced to a rather large spot on each eyelid. Toes not
so much palmate as in the preceding species.

H. delitescens. H. delitescens L. C. I. c. p. 181. Holbrook, 1. c. pi. 32.

Variable at will from cinereous to brown, more or less distinctly spotted with
darker. Differs especially from the former in having a larger and blunter head.
The exterior portion of the thighs and the whole of the under side of the arms
and legs i3 yellow, the legs also are not barred, but varied and speckled with
darker, chin and throat smooth. Toes as in the preceding species.

Inhabits Georgia. In the spring it is found very numerous under the bark of
dead trees.

H. pickeringii. Hylodes Pickeringi Holbrook, 1. c. pi. 34.

Above smooth, light-brown or fawn-color with lines and spots or specks of
dusky, the first of these most frequently arranged so as to form an oblique angled
cross, a line of the same color on the top of the head forming an angle pointing
backwards, and another extending from the nose to the insertion of the arm,
this last sometimes not apparent, indeed all the dusky marks are frequently so
indistinct as to be scarcely observable, beneath whitish granulate, arms and legs
marked with transverse bars of darker or dusky.

This is a true Hyla and wot an Hylodes : it is never found in the water, but on
the leaves of plants and under the bark of dead trees.

H. ocularis. H. ocularis Daudin, 1. c. p. 32. Hylodes ocularis Holbrook,
pi. 35.

Above brown or bronzed or silvery grey, very finely speckled with dusky or
darker, a tolerably wide band of black proceeds from the tip of the nose to the
middle or beyond the middle of the sides, this is bordered beneath with white.
Chin and under side of the thighs speckled with black. Legs speckled like the
back and more or less spotted and barred with dusky, fingers and toes all fur-
nished with small disks.

Length .6.
^Inhabits Georgia. The smallest of all known Ranina. From the small size
of this and the preceding species, the web between the third and fourth toes is
not very perceptible.

SCAPHIOPUS Holbrook.

S. solitarius Holbrook, iv. pi. 27.

Above olive brown, dusky, of various shades, with blotches of darker or black,
and two lines of pale yellow or whitish from the orbits to the vent, and some-
times another of the same color on the sides ; tympanum small, pale olive. Back
warty, the warts of different sizes and colors, some of them dark brown or
dusky, others orange colored or red.

This curious animal so much resembling a frog in its maxillary and palatine
teeth, and a toad in its pnrotids, the form of its body and its subterranean life,
gives a fair example of some of our systematic arrangements. It has been
placed by M. Dumeril among the frogs, when to all intents and purposes it is

430 [December,

as much a toad as any of the genus Bufo. The flat spur, as it has been
called, at the root of the first toe on the internal margin of the metatarsus, is
nothing more than a much developed form of a scale or disk occupying the same
situation in most animals of this family.

Although very seldom seen except when accidentally turned up by the spade
or the plough, yet the Scaphiopus is a very common animal in Georgia. When-
ever the South East storms occur at the Autumnal Equinox, the surface of the
earth is covered with them, and their dismal croakings add to the horror of the
howling winds and the deluges of water which pour down from the heavens.

They have also been found in Connecticut and Massachusetts. When placed
upon the ground they dig with remarkable celerity, and soon entirely bury
themselves in the earth.

BUFO.

B. musicus Daudin 1. c. p. 92, pi 32. B. lentiginosis Holbrook v. pi. i.

This species like all its congeners varies very much in color and in the form
and disposition of the spots. This variation depends entirely on the will of the
animal. It is generally however of a very dark dusky, sometimes light grey
and even reddish. I cannot conceive how it has ever received the name oilen-
tiginosus, which as I have shown before under Telmatobius is as unlike this
animal as any species can be. The Rana lentiginosa of Shaw, of which he
gives in his general Zoology a tolerably good figure, although copied from Cates-
by, is perfectly smooth, more resembling a frog than a toad, and therefore well
called by him the land frog ; whereas the B. musicus is very rough and makes
no approach to a frog in its form and habits. It walks rather than hops. Bar-
tram's red toad of Florida was a mere variation of this species, the difference
being nothing more than an accidental or voluntary change of color.

The species figured under the name of Bufo cognatus of Say, in the explora-
tion of the Red River of Louisiana by R. B. Marcy, Capt. U. S. A. appears
to be this animal.

B. americanus L. C 1. c. Holbrook 1. c. pi. 4.

This species like the preceding varies very much in [color; it rather hops
than walks.

B. erythronotus Holbrook, I. c v. pi. 2.

Not having been able for years to obtain a living specimen of this animal I
shall say nothing more of it than that it bears not the sliuhtest resemblance to the
Bufo lentiginosus (B. musicus) as stated by Mr. Girard in Proceed. A. N. S. vol.
p. 86.

B. qtjercicus Holbrook, 1. c. v. pi. 3.

Above thickly covered with small warts,, dusky with a few irregular black
spots, many of the warts particularly those on the sides whitish or reddish; a
very distinct line of one of these colors runs from the point of the nose along the
vertebral column to the vent. Beneath the body is granulate, white, more or
less varied particularly on the fore part with black. There is a supraorbital
ridge straight and very distinct ; upper jaw slightly emarginate. Thumb equal
in length to the first finger, feet with two calli, the interior one exactly resem-
bling a toe and equal in length to the first toe.

Length 1. 1, arm *6, leg I inch.

Very common in Georgia in wet places, under logs and pieces of wood.

ENGYSTOMA Fitzinger.

E. cyrolinense. Microps Wagler, Stenocephalus Tschudi.

Varying at will very much in color, from dusky to brown, olive-cinereous or
yellow cinereous, more or less varied, spotted or speckled with black, beneath
pale brownish white, punctate so as to appear spotted.

Very common in the low country of Georgia under logs. In De Terville's
Natural History, Bosc confounds this animal with Daudin's Bufo gibbosus. He

1855.] 431

says he found it in South Carolina, but brought none thence to France, as the skin
was so thin and tender, that he was unable to preserve or even describe it : to
me the skin appears as strong as that of any other species of Ranina of the same
size.

These are all the species of this family of reptiles which I have been able to
see in a living state. I hold it to be impossible for any one to make a correct
description of an animal which has the power of changing its color at will, un-
less he has it alive ; and this power they all possess in a greater or less degree ;
when preserved in alcohol they always fade. The difficulty of procuring de-
scriptions made on the spot where the objects are found, has rendered this part
of natural history as confused and unsatisfactory, as the researches of bota-
nists who draw up their accounts of plants from dried specimens.

There are a few species with which I was formerly acquainted but which I
have not met with or been able to obtain. Among these are a frog which seemed
intermediate between R. pipiens and R. palustiis, two Hylae inhabiting Georgia,
and another probably an Acris which I formerly described in the Annals of the
Lyceum of New York under the name R. pumila. Mr. Baird describes some
in the Proceedings of our Society, which have been sent to him from Texas,
Mexico, and other remote parts of our country. These I do not here treat of,
being certain that I shall never see them in a living state. There is in the
waters of ponds and ditches a small frog whose note exactly resembles the bleat-
ing of a lamb, so truly as to deceive any one. This animal I have seen, but
never succeeded in catching it. It is very common in Georgia and I have
heard it as far north as Norfolk in Virginia. It is left to the inhabitants of those
parts of our country to determine what it is.

Observations on the North American species of Bats.

By John Le Conte.

Notwithstanding all that has been written by Rafinesque, F. Cuvier and Dr.
Bachman on the bats of North America, a diligent study has shown me consid-
erable errors in the accounts of all. Before proceeding to a description of these
animals, it is necessary to remark, that every bat which I have seen, has an uncer-
tain numberof transverse wrinkles or plaits on the outer portion of the ear, and has
the toes furnished with rather long and fine hairs, as it were fimbriated, wherefore
these two marks are omitted as furnishing no good specific characters. All our bats
except the Molossus belong to the same genus ; the trifling difference in the
number of the teeth does not afford a sufficient reason for considering them as
different. M. F. Cuvier in the first volume of the Nouv. Annales du Museum,
divides the genus into three sections, the Serotinoids, the Noctuloids and the
Murinoid?. The form of the cranium seems to be the chief mark in distin-
guishing them from each other. The Serotinoids may be described as having
the cranium somewhat inflated and rounded, the jaws short, widened and ele-
vated at the extremity, the facial angle 43°. The European species as far as I
can collect, have four upper incisors. In this country we have but two belong-
ing to this section, the Noveboracensis and the cinereus, both of which have but
two upper fore teeth. The Noctuloids have the skull rather straight and flat on
the top, and the jaws more extended, the facial angle is 30°. They all have
four upper incisors except the crepuscularis which has like those of the first di-
vision but two. The Murinoids are known by having the cranium inflated and
rounded, the jaw3 elongated a little raised in front with a considerable depres-
sion separating them from the cranium, the facial angle is 22°. The V. pallidus
which has buc two upper fore teeth appears to me to be a Murinoid ; all the
rest have four upper fore teeth. As for what has been called a Plecotus (even
by myself) it certainly belongs to this division : it differs considerably from
the Plecotus auritus of Europe, in the form and position of the ears. I am not
writing about the animals of a foreign country, and therefore I say no more on

u

432 [December,

this head, than that the P. aurilu3 as far as regards the skull appears to be a Seroti-
noid. My remarks on the Molossus will appear when I come to describe that
species.

vol. i. p. 184. V. rubellus Palisot de Beauvois, Catalogue of Peale's Museum.
V. monachus and tessellatus Rafinesque. Nycticeius Atalapha and Atalapha
americana ejusd. Taphyzous rufus Lesson. It likewise belongs according to
Leach to his genus Scotophilus, Taphizous rufus. Harlan's description is made
from an infamous figure in Wilson's Ornithology.

Dentition. Upper Jaw, incisors l-l simple, distant. Canines 1-1, hollowed
out behind with a perpendicular septum dividing the concavity for its whole
length False molars 1-1, concave on the outer and inner surfaces, the calca-
neum produced behind into a lobe. Molars 3-3, the first and second with six
cusps, three exterior, small apparently formed from the basal ridge which sur-
rounds the teeth ; two intermediate and one exterior ; the third with three cusps
ranged transversely and one posterior.

Lower Jaw. Incisors six, biemarginate. Canines 1-1. False molars 2-2, the
anterior one very small. Molars 3-3, with five cusps, two exterior and three
interior, the basal ridge wanting interiorly.

A young one taken from the mother's breast, had in the upper jaw, the inci-
sors, the canines, and the false molars; in the lower jaw, the canines and
one false molar on each side, all of them hooked like the claws of the toes.

Face black, hairy ; nose blunt, emarginate. Ears brown, short, round, almost
concealed in the fur, a little hairy, orillon cultriform, blunt, one half the length of
the ear, and sparely hairy. Membrane dusky, generally reddish brown along
the antibrachium, and more or less so along the great part of the length
of the fingers ; a portion of the base on each side is hairy, so as to form a straight
line from the shoulder to the foot ; spot at the base of the thumb white, a few
hairs of the same color or of rufous extend down the fourth finger: beneath
from the body to the end of the os humeri it is thickly covered with rather long
hair, along the fore arm more sparsely so, for nearly one half the wridth
of ihe wing. The interfemoral membrane includes the whole of the tail,
on the upper surface it is densely hairy, the hair being of the general color
of the body, sometimes tipped with white, never cinereous at the base ; on the
under surface it is naked except at the base, where there is an oblong patch of
hair extending along the tail, for one third of its length. Feet black, thickly
covered with hair.

Color extremely various, scarcely any two being found exactly alike. A very
common variety has the hair above four-colored, that is to say, black or dark
cinereous at the base, then yellowish brown or fawn-colored, afterwards dark ru-
fous or reddish brown, or orange-tawny or purplish brown, finally very slightly
tipped with white, very often with a distinct ring of a darker shade around the
neck. Beneath, the hair is three colored, the base dark or light cinereous, then
one of the other colors, and tipped with white, so that the pelage is varied
with cinereous and the other colors, and powdered over with white : this last
color forms a conspicuous spot at the axilla. The pelage is however above
sometimes only three-colored, being as before dark cinereous at the base, then
pale yellowish, and afterwards bright light rufous or orange without any white
tips or very few of them, so as to appear uniformly rufous or orange, be-
neath rather paler. The lighter the color above, the more does the membrane
incline to reddish brown. They have been found of a uniform cream color, and
even white, the base of the hair being always cinereous, but are most com-
monly of different shades of rufous or tawny. The darker the ground the
more apt are the hairs to have white tips, although some of dark shades have
been found without any of these.

Length 2 in. Tail 1.6. Extent 11.3. Head -7. Ears -25. Orillon -1.

This, the commonest species in the United States, is found everywhere from
Canada to Florida, from one end of the country to the other equally numerous.
It may even extend into South America, as the description by Lesson of the V. bo-

1855.]

nariensis in the Zoology of the voyage of the Coquille agree? very well ; but the
figure of the animal which accompanies it is so wretchedly executed, as to be
of no use in determining the point.

V. cinereus. Palisot de B(;auvois, 1. c. V. pruinosus Say, Long's Expe-
dition vol. i. p. 168.

Dentition the same in every respect as in V. noveboracensis. Hair above
four-colored, that is to say, black at the base, then reddish-brown, afterwards
black, and tipped with white: beneath two-colored, the lower half dark cine-
reous, the upper yellowish or grey, so that the pelage of the animal appears on
the upper side, variegated with reddish brown and black, and powdered over
with white, this latter color so disposed as to form transverse curved and wa-
ving lines, on the under side, yellowish grey on the sides and cinereous mixed
with grey on the other parts. Head above and throat yellowish grey; face
hairy ; chin very dark brown : nose flat, blunt, emarginate. Ears black, sim-
ple round, densely covered both within and without on the anterior portion, with
short yellowish grey hair, leaving a distinct narrow, naked margin. Orillon
cultriform, blunt and sparsely hairy, half the length of the ear. Membrane
dusky, for one third its breadth along the arm brown ; sometimes beyond this
spotted with brown, very much so near the body. A portion next the body in
a straight line from the shoulder to the feet is hairy. There is generally a
small white hairy spot at the anterior joint of the humerus (sometimes how-
ever the hairs are pale brown, not white), and another at the base of the thumb.
The membrane beneath is hairy as far as the third finger for nearly half its
breadth, this hairy space joins another of the same width along the sides, and
there is generally a large white spot at the axilla or insertion of the humerus. In-
terfemoral including the whole of the tail, above densely hairy, beneath only
at the base, forming a roundish deeply emarginate patch, feet black, sparingly
hairy.

Length 3 inches. Tail 2-1. Extent 16-8. Head -94. Ear -48. Orillor, .25.

I have given to this species the name imposed upon it by Palisot de Beauvois,
ann. 1796 in the catalogue of Peale's Museum, although I am not certain that
it differs from the V. lasiurus of Linnaeus. This last is said by Temminck to
inhabit Cayenne and North America. The description of Temminck suits our
animal very well, but whether the two are the same, remains yet to be deter-
mined. The figure in Schreber is undoubtedly taken from a V. noveboracensis
The V. bonarien3is described and figured by Lesson in the Zoology of the voy-
age of the Coquille vol. i. p. 137 tab. 62, may be either the one or the other,
the figure is so excessively bad that nothing can be made of it. This is the
largest of all the bats found in the United States, it is not common, and is seen
more frequently in the middle than in the northern or southern states.

I have never had it in my power to examine more than six or seven individ-
uals of this species, and therefore cannot say how far the colors may vary.

V CREPCSCULARIS.

Dentition the same as in the two former species.

Hair black, above tipped with chestnut brown, beneath with paler or cinereous
brown more or less distinctly varied by the black of the lower part of the hair.
Head rather depressed, face flat, black, naked, with a few scattered, long, coarse
hairs, and a small wart over each eye ; nose broad, flat, blunt, emarginate ; chin
with a small double wart on the lower part. Ears shorter than the head, tri-
angularly ovate, rounded at the point, slightly emarginate on the hinder edge,
dusky, naked. Orillon short, dolabriform, blunt. Membrane very thin, dusky,
naked except a narrow space next the body. Interfemoral including the tail
except the two last joints naked, except a small portion of the base which both
above and beneath is slightly bjairy.

Length 2-2. Tail 1-4, naked part -15. Extent 10-5. Head *7. Ears -3. Oril-
lon -19.

Inhabits Georgia.

This is the V. creeks of F. Cuvier, this name however being unmeaning and

434 [December

indeed ridiculous, I have substituted for it the name given to it by me many
years ago and mentioned in Dr. McMurtrie's translatioa of the Regne Anunale.

All the species of American Bats described by the illustrious French Natural-
ist in Xouv. Annales du Museum vol. i. p. 1 were given by me to his brother the
Baron, aud I distinctly remember this species as having been among them.

V. fuscus. Palisot de Beauvoisl. c, V. arcuatus Say, Long's expedition 1. c,

with paler or greyish or yellowish cinereous. Face black, naked with a few coarse
hairs. Nose flat, blunt, emarginate, rugou3. Ears short, black, naked except
for about one fourth their length from the base on the outer side, emarginate be-

Length 3-8. Tail 1-5, naked part -1. Extent 11-7. Head -75. Ears -45. Orillon -2.

Inhabits from New York to Florida.

This with the four preceding are very nearly related to each other, so much
so as to be easily taken the one for the other ; we therefore find thtm all called
V. arcuatusof Say or V. caroliniensis of Geoff. St Hilaire, these two being con-
sidered identical. They however differ in the shape of the ear and in the oril-
lon. These two parts alone I have found in all species of Vespertilionidae to
afford unvarying characteristics.

The fuscas has the ear somewhat triangular, very concave on the outer edge
and emarginate near the tip, the orillon acinaciform.

The carolinensis has the ear hairy for oue half its length, ovate and emarginate
on the hinder edge, the orillon is lanceolate and blunt.

The ursinus, ear oval, eutire ; that is to say not at all emarginate, the orillon
acinaciform and obtuse.

The phaiops, ear somewhat triangular, sinuous or bi-emarginate on the outer
edge, orillon oblong, blunt.

The caroli has the ears ovate, emarginate behind almost from the tip to the
base, and the orillon lanceolate, blunt, rounded at the point; a little curved on
posterior edge.

V. pulverulentus Tern. ii. p. 235. V. Audubonii Harlan, Med. & Phys. Re-
searches, p. 90. V. noctevagans L. C. olim.

Dentition the same as in the five preceding species, except that the false molars
in the upper jaw are 2-2. the anterior one frequently pressed inward by the pos-
terior one ; and in the lower jaw the false molars are 3-3.

Hair black or very dark brown, generally tipped with white or pale brown, or
brownish grey in rather a scattering maDner. Face somewhat hairy, nose blunt
emarginate; fore part of the throat with a large wart. Ears moderate, ovate,
blunt, the lower half covered with hair, granulate within the outer edge which
is somewhat revolute and entire, anterior part of the helix highly developed,
prominent and straight, forming a winged appendage near the head. Orillon
short, cubiform, blunt, membrane naked black or dusky, interfemoral including
the tail, except the last and one half of the penultimate joint, thinly covered for
one half its length with long fine hairs like those of the body tipped very slightly
with greyish, the under side is furnished with distant hairs disposed in lines.

Inhabits from New York to Georgia.

This species has the head of a Noctuloid and the teeth differing from all the
others. Is sometimes found entirely black.

V. subulatus Say. Long's Expedition, vol. ii. p. 65.

Dentition. Upper jaw, incisors 2-2 distant by pairs, the anterior larger and
emarginate, false molars 3-3 anterior one small, intermediate one minute and

lower jaw are also the same except that there are 3 false molars on each side,
the two anterior of which are not half the length of the posterior.

Inhabits everywhere. Varies much in color from the darkest chesnut to light
fawn. With this species, commences the family of Murinoid bats.

V. lucifugus L. C. in Dr. McMurtrie's translation of the Regne Animal.

Dentition the same as in V. subulatus.

Hair dark plumbeous, above tipt with dark chestnut brown, beneath with pale
brown. Face black, hairy, nose flat, blunt, rugose, emarginate. Ears black,
naked, except about one fourth their length outwardly from the base, so much
emarginate outwardly as to appear hooked. Orillon lanceolate, blunt, a little
convex on the outer edge, straight on the inner. Membrane black, naked except

Much resembles the preceding but has the ears of a different form as well as
the orillon.

V. georgianus Cuvier 1. c. p. 16.

Dentition the same as in subulatus except that the posterior false molar of the
upper jaw has an interior, basal, bi-emarginate cusp formed from a prolongation
of the calcaneum of the tooth, and the canine of the lower jaw has an interior,
blunt, basal lobe.

Hair dark plumbeous, above tipped with bright rufous, the hair so arranged
that the pelage appears varied with black particularly on the upper part of the
back, beneath the hair is tipped with fawn color or rufous. Face black, very
hairy, nose flat, blunt, rugose, emarginate. Ears perfectly naked, short, ovate,
blunt, slightly emarginate on the outer edge, orillon oblong," blunt, straight.

Said by Dr. Bachman to be same with the V. subulatus which it very slightly
resembles.

V. macrotis. Plecotus macrotis L. C. McMurtrie's translation of Cuvier's
Regne Animal, Appendix.

Dentition. Upper jaw incisors 2-2, the anterior bilobed, the posterior smaller.
False molars 2-2, the anterior one very small, the base of the posterior one pro-
jecting backwards into a fiat, sharp surface. Molars and canines as before.
Lower jaw, incisors 6, crenate. False molars 3-3, the two anterior small. Molars
and canines as in other species.

Hair black above slightly tipped with dark chesnut brown, beneath with
whitish, sometimes entirely black both above and beneath, except a small cinere-
ous space near the arms. Face black nakedish, with a prominent tubercle on
each side behind the nostrils, these tubercles converge towards each other,
leaving a considerable hollow space on the top of the head, which is flat,
the nose not bilobed. Ears ovate broad, naked, dusky, much longer than the
head, bending forwards, the hinder margin somewhat involute, the inner margin

Inhabits Georgia.

This species though at first sight very much resembling the so called Plecotus
auritus of Europe, differs from it particularly, in having the ears perfectly
separated at the base, and wants the small lobe or blunt tooth on their inner
edge. The cranium is entirely that of a Murinoid bat, and the teeth of the two
species agree.

V. PALLIDUS.

Dentition. Incisors 1-1, large simple. Canines 1-1, a little concave on the
outer side, with an internal, basal, rather blunt cusp. False molars 1-1. Molars
first and second as in all the others, the third with fout cusps, three of them
transverse, the interior one smaller, and one posterior.

Lower jaw incisors .4. False molars 2-2, the anterior one smaller, rather
interior. First and second molars as in others, the third with three cusps, not
transverse, the interior one larger and transversely deeply emarginate.

Hair light fawn-colored, tipped with darker, beneath paler. Face hairy dark
brown. Nose rounded, emarginate. Ears longer than the head, oval, entire,
very pale dusky brown. Orillon nearly one half the length of the ear, linear,
blunt. Membrane thin naked brown. Interfemoral including the tail except
the two last joints.

Length 3. Tail 1.5. Naked part .1. Extent 12.1. Head .9. Ears .95. Orillon .4.

Inhabits California.

Differs from all the other species in having but 4 lower incisors ; I hesitate
therefore to arrange it with the Serinoid or Murinoid Bats and place it at ihe
end of these two families.

Dentition. Upper jaw, incisors 1-1, simple, distant, convergent at the points so
as almost to meet. Canines 1-1 curved outwards, so deeply grooved in front ai
to appear almost double. False molars 2-2 the anterior one very small, the
posterior one with a sharp basal cusp. Molars 3-3, the first and second with
seven cusps 3 exterior, 2 intermediate and 2 interior, the third with five cusps 2
exterior, 2 intermediate and 1 interior. Lower jaw incisors 6, approximate,
emarginate. Canines 1-1, simple slightly curved inwardly. False molars 2-2,
the anterior one smaller. Molars 3—3 each with 2 exterior and 3 interior cusps.

Hair fine and soft, cinereous tipped with brownish dusky, beneath rather paler.
Face naked, nose turned up, broad, blunt, channeled on the top, crenately serrate
on the front margin, upper lip very large, tumid, pendulous, with eight perpen-
dicular grooves. Ears projected forwards, broad, rounded, not united on the
top of the head, but running down the sides of the forehead to the root of the
nose, outwardly produced downwards and forwards to the corner of the mouth,
and very obtusely emarginate about one third of the distance from the top, the
upper part has inwardly from eight to ten small rather pointed tubercles near its
margin. The ears have likewise an internal fold and a small thick round fleshy
lobe opposite the orillon and concealing it from view. Orillon small oblong
and rectangular; the lower part of the outer edge of the ear is double as in
many other animals, for instance in cats and dogs. Membrane rather thicker
than common, naked, dusky, the interfemoral above more or less thinly covered
with short and soft hair, including the tail, one third part of which projects be-

438 [December,

It ia very remarkable what confusion exists in authors with regard to the
genus of this animal. It was called by Geof. St. Hilaire in 1805 Molossus,
afterwards in 1814 Nyctonomus, again was described by him as Rhinopoma
caroliniense ; it likewise belongs to the genus Dysopes of llliger and the Diuops
of Sari, yet none of their descriptions either of the genus or the species appear
to be correct ; they all seem to have confounded this North American bat with
the Melossus velox certainly an inhabitant of South America, and plainly be-
longing to a different genus. Mr. Cooper in the Annals of the Lyceum of New
York has made two species of it, Molossus cynocephalus and M. Lecontii.
founding the difference in the plaitings of the ears in the latter. As I have before
observed this is a character common to all bats : in dried specimens these strife
frequently are evanescent.

M. Temminck's remark on the fore teeth of his Molossus that they vary in
number and are pushed out of place by the canines is a mere supposition. Age
of course causes the teeth to fall out, when the base of the canines will advance
somewhat, and cover the open alveoli, but in most cases, these always remain
open, or at most one or two of them may close as is observable in other animals
that have the misfortune to lose one or more of their teeth. In the M. velox
which has but four incisives in the lower jaw, placed in front at the base of the
canines, he supposes them to have been once situated in a space between the
canines, and afterwards to be pushed out in front (without any presumable
function) of their almost united bases ; an impossibility. This position of the
lower fore teeth is to be seen in every age of the animal.

I have observed fifteen individuals of this species : one had no incisors in
the lower jaw; two had five ; three had four, and the rest six.

This Bat is so numerous in the cities of the South as sometimes to render
houses uninhabitable, by their disagreeable smell, and the noise which they
make in moving about. It appears to be equally common in the island of
Cuba.

Of Bats described by others, the following with but one exception I have never
Been, Dr. Bachman in the viii. volume of the Journal of this Society, mentions
four species : V. monticola he says resembles Say's bat; what species he calls by
that name I cannot discover. V. virginianus seems to be the V. humeralis of
Rafinesque. I have not seen this last for many years, and therefore cannot pro-
nounce definitely concerning it. The V. Leibii and Californicus are equally
unknown. Of Mr. Rafinesque's species, it is impossible to determine the follow-
ing ; there is a good reason however to doubt, whether they are distinct from
others which are well known ; V. cyanopterus, V. melanotis, V. calcaratus,
V. phaiops afterwards described in his Annals of Nature No. 1 as Eptisecus
melanops, V. megalotis, V. mystax afterwards called in the Journal de Physique
vol. lxxxviii. p. 417, Hypexodon mystax and Eptisecus melas, M. Cuvier's V. Sal-
arii may be the fuscus, and his subflavus the Caroliniensis ; his crassus like-
wise I cannot determine. M. Temminck's V. erythrodactylus, Temm. vol. ii.
page 235, remains among those unknown by me.

Notices of some new and little known Birds in the collection of the JJ. S. Exploring
Expedition in the Vincennes and Peacock, and in the collection of the Academy of
Natural Sciences of Philadelphia.

By John Cassin.

1. Muscipbta cyaniceps, nobis.

Form. Bill rather long, wide at base, abruptly compressed towards the end
and furnished with about six pairs of strong rigid bristles at the base, some of
which are as long as the bill. Feathers of the head above somewhat elongated
and probably erectile, wings rather long, fourth primary longest, tail long, wide,
central feathers but slightly exceeding others next to them, tarsi rather long,
slender, tees short, feeble.

Dimensions. Total length (of skin) about 6^ inches, wing 3, tail 3$ inches.

1855.] 439

Colors. Entire head and breast dull blue, every feather having a longitudinal
central line of a paler shade or light blue. Upper parts of the body, the abdomen
and several of the outer feathers of the tail fine rufous, palest on the abdomen,
quills dark brown, secondaries edged with rufous. Central feathers of the tail
dark brown, which is the color also of the inner webs of the feathers next to
them. Bill dark, tarsi lighter.

Hab. Philippine Islands. Spec, in Coll. Ex. Exp. in Nut. Mus. Washington.

Obs. This is a very handsome small species of this genus, and bears a re-
semblance to Muscicapa borbonica, Gm. Buff. PI. Enl. 573, fig. 1, which is an
inhabitant of the islands of Madagascar and Mauritius. From that species the
present birds may easily be distinguished by the pale longitudinal lines on the
blue parts of the plumage, in addition to which it is larger and has the tail dis-
proportionately longer.

The only specimen that I have ever seen of this species is in the collection of
the Exploring Expedition, and is labelled as having been obtained at the Philip-
pine Islands. It belongs strictly to the same subgeneric group as M. borbonica,
and shows a general relationship to several other African species. It will be
figured in the forthcoming Atlas to my volume on the Birds of the Exploring
Expedition.

2. Laniarius multicolor. G. R. Gray, Genera of Birds, i. p. 299, pi. 72.
Hab. Western Africa. Spec, in Mus. Acad. Philad.

Obs. A single specimen of this handsome species is in the collection of the
Academy, and was obtained by Dr. MacDowell, on St. Paul's river, Western
Africa.

3. Hyphantornis flayigula, Hartlaub, Rev. Zool. 1845, p. 406.
Hyphantornis Grayi. Verreaux, Rev. et Mag. de Zool. 1851, p. 514.
Hab. Gaboon country, River Moonda. Spec, in Mus. Acad. Philada.
According to Mr. DuChaillu, in whose collection are numerous specimens, the

1 irds described as above are the two sexes of the same species. H. flavigula is
the female.

In Mr. DuChaillu's notes now in my possession I find the following in relation
to this species :

" This bird frequents the borders of the woods, or more frequently the tufted
bushes which are not found far from habitations. It is always in these thickets,
and if it were not for its cry, which indicates the place where it may be found,
it would be very difficult to procure it. It is always in company with its female,
and does not live in troops. Sometimes two pairs may be seen on the same tree.
This bird generally makes its nest in these very thick bushes and in the midst
of the leaves ; the two nests in my collection, I found within ten yards of a
house, and both contained eggs of a rose color."

"This bird is found in the dry season and at the commencement of the rainy
season, when it disappears."

4. Sycobius nigerrimus, (Yieill.)
Ploceus nigerrimus, Vieill.

Hab. Gaboon country and River Moonda. Western Africa.

Several specimens of this rare species, remarkable for the uniform deep black
of its plumage, are in the collection of the Academy. Some of them were col-
lected by Mr. DuChaillu on the River Moonda, and others have recently been
obtained in a collection from the Gaboon country, obtained in New York by Mr.
John G. Bell.

5. Symplectes princeps. Bonap. Consp. Av. p. 107.
Hab. Lagos, Western Africa.

A specimen of this bird is in an interesting collection made by John L. Burt,
M. D., of the U. S. Navy, at Lagos, and recently presented to the Academy.

6. Hyphantornis castaneofusca, (Less.)
Ploceus castaneofuscus, Lesson.

This bird is in Dr. MacDowell's collection from St. Paul'6 river, Western Af-
rica.

Merops fasciculatus. Lath. Ind. Orn. i. p. 275 (1790.)
Hab. Sandwich Islands. Spec, in Mus. Acad. Philada. and Nat. Mus. "Wash-
ington.

The specimens in the collection of the Academy were brought by Dr. Town-
send from the Sandwish Islands, and in the collection of the Expedition in the
Vincennes and Peacock are numerous specimens which appear to represent both
sexes. The female much resembles the male, but is smaller and with the co-
lors duller, with tinges of brown on the throat and occasionally on the upper
parts of the body. Both sexes have the tail long.

At present, I regard the bird figured by Reichenbach in " Die Volstandigste
Naturgeschichte " Birds, pi. 604, fig. 4099, and described in " Handbuch der
speciellen Ornithologie," Scansorias p. 333, as a distinct species, though given
by that distinguished naturalist as the female of " Mohoa fasciculatus " (fig.
4098). It is as follows :

9. Mohoa braccata, nobis.

Smaller than the preceding, bill less curved, tail moderate, central feathers
longest.

Tibiae yellow. Head above black, throat and breast with every feather having
a small terminal spot of ashy white, back, frump, and under parts dark chocolate
brown, with a few longitudinal lines of white on the back. Wings and tail
brownish black, the former edged with white at the shoulder. Bill and feet dark.

Dimensions. — Total length 8J inches, wing 3£, tail 3J inches.

Hab. Sandwich Islands. Spec, in Mus. Acad. Philada.

The only specimen that I have ever seen of this species was brought by Dr.
Townsend from the Sandwich Islands and is marked as a male. It has heretofore
in the collection of the Academy been mistaken for Certhia pacifica Gmelin,
but is clearly not that bird and but little resembles it as far as can be de-
termined from the plate in Audebert, or from the descriptions by Gmelin and
Latham. In addition to these two there is a third species of this genus.

10. Mohoa angustipluma, (Peale.)

Entomiza angustipluma. Peale Zool. Exp. Vincennes, Birds p. 147 (1848.)

Plumage of the head, neck and breast, with the webs of the feathers com-
posed of few filaments and presenting an open or skeleton like texture, many
feathers of the throat terminated with bristles. Bill curved, wings rather long,
tail long wedge shaped, legs and feet strong. Larger than either of the two pre-
ceding.

Head and neck above dark brown, every feather having a longitudinal central
stripe of dull white, tinged with greenish yellow on the latter. Other upper
parts including wings and tail, brown, on the back with longitudinal stripes of
white, quills and tail feathers edged with olive green on their outer webs, rump
tinged with olive. Wide stripe from the base of the bill under the eye, ending
in a large spot on the cheek, black.

Throat dull white tinged- with yellow, breast and aVdomen dull white, every
feather margined with dull brown, flanks and under tail coverts dark rufous,
bill and legs dark.

Dimensions. Total length 13^ inches, wing 6, tail 6 J inches.

Hab. Hawaii. Spec, in Nat. Mus. Washington.

One of the most remarkable of the ornithological acquisitions of the Expedi-
tion in the Vincennes and Peacock, and clearly of this genus. The feathers of
the head and breast in this bird present a singular character on account of the
filaments composing the webs being unusually few, and at such a distance from
ei ch other as not to touch, nor become adherent. The specimen described may

1855.] 441

not be adult and its sex is not stated. It does not appear to be related to Stri-
giceps, Lesson.

This species will be carefully figured in the Atlas to my volume on the Quad-
rupeds and Birds of the Exploring Expedition now nearly ready.

Note on the Miocene and Post-Pliocene deposits of California, with descriptions of

two new Fossil Corals.

By T. A. Conrad.

Post-Pliocene deposits of shells occur at various places on the coast of Cali-
fornia, as Santa Barbara, San Pedro, <fcc, but I have seen specimens of Miocene
fossils from no other locality on the coast than near the former town, where they
were obtained by Dr. Heermann, who informs me that they are very little elevated
above the sea, and that the Post-Pliocene fossils rest immediately upon them.
This Miocene deposit consists chiefly of fine loose brown sand and small corals,
the most of which are a species herein described as Idmonea Californica. The
shells have been described in the Proceedings for February, 1855, p. 267, and
consist of Mercenaria perlaminosa, Pecten Heermanni, Diadora crucibuliformis,
Pandora bilirata and Cardita occidentalis.

The Mercenaria and Pecten are closely related to species of the "Virginia
Miocene, and indeed there is an extraordinary analogy in all the above mentioned
shells to species of the Atlantic Miocene deposits ; and what is equally remark-
able, they have no resemblance to the existing California species, many of which
are imbedded in sand above them; affording perhaps a stronger contrast between
the two groups than occurs in any other part of the world. The Atlantic
Miocene and Post-Pliocene on the contrary contain a few species in common and
others which are analogous.

'O'

IDMOXEA, Lamourouz.

Idmonea Californica. Branches compressed, slender, bifurcated ; tubular open-
ings projecting, irregularly grouped, but disposed to form in transverse series ;
longitudinal line between the openings or cells, microscopic or obsolete ; reverse
surface plano-convex, tranversely wrinkled and slightly furrowed ; section exhi-
biting 15 to 20 angular pores.

The branches of this species are about £ of an inch wide. I havo not seen
any among them anastomosed. It belongs to the genus Crisisina, D'Orbigny.

Among these corallines, is a species of Tubulipora, a Retepora and a Lichenopora
which may be named

Lichmopora Californica. Adhering ; tubular openings numerous, arranged in
irregular branching rays ; central depression rather deep and with numerous
unequal pores. Diameter about £ of an inch.

Post-Pliocene.

Near Santa Barbara and San Pedro, Dr. Heermann collected a number of fossil
shells of the same species which inhabit the adjacent coast, among which are
Platyodon cancellatum, Conrad, Schizothcerus JVuttallii, Con., Vinus Nuttallii, Con.,
Tellina nasuta and Tapes diversa, Sowerby, among the bivalves, and a number of
univalves.

.Description of a new species of Pentamerus.
By T. A. Conrad.

Pentamerus laqueatus. Ovate ; larger valve inflated, with about 28 angular ribs ;
mesial ridge but little prominent, with 5—6 ribs rather larger than the others ;
smaller valve slightly ventricose with a wide but shallow depression on each
side ; basal margin sinuou3.

Locality. Delphi, Indiana. Mr. Hill. This species resembles P. Aylesfordii,
but is quite distinct.

Description of two new species of Ilesperomys.

By John Le Conte.

Dr. Bachmao, ia Audubon's Quadrupeds of North America, states that the
Hesperoinys leucopus inhabits the southern regions of our country. Although
I have resided in the lower part of Georgia for a great portion of my life, I never
saw it there. There are however two species which he seems to consider the
same, and which he has confounded with the northern animal. An accurate
and detailed description of these will show very distinctly how much they differ.
These two species are the gossypinus and the cognatus. The first was described
by me in the Proceedings of the Academy, vol. vi. p. 411, and is very easily
distinguished from the other by its larger size. The second, which I was led by
the assertion in the Quadrupeds of North America to consider as the Hesper-
omys leucopus, a more careful examination and comparison have shown to be
entirely distinct. It appears in some degree allied to the H. gossypinus, but its
manners are very different.

H. COGNATUS.

Hair dark plumbeous, above tipt with dusky and rufous-brown, with the
latter more particularly on the sides, beneath with white, but in such a manner
that the dark color of the lower portion of the hair shines through tbe
white. Head large rather blunt, upper half of the cheeks inclining to rufous,
ears large, open, naked except the lower part of the outer edge, feet flesh-color,
tail slightly hairy, beneath whitish.

Length 3.4 in. Tail 2.2 in. Head 1.2. Fore leg 1.1. Hind leg 1.6.

This animal is easily distinguished from the H. leucopus by the under parts
never being of the pure and snowy whiteness that gives so much beauty to the
northern animal; they are however very nearly related. The relative difference
of the fore and hind legs is not so great as to cause it to leap and not to run
when endeavoring to escape pursuit. In size its dissimilarity to the H. gossy-
pinus is most remarkable. This last also has tbe under side of the tail pale
brown. The other likewise wants tbe narrow whitish border to the ears.

Inhabits Georgia and South Carolina; in the winter it frequents houses like
its analogue in the north.

I have the pleasure to add to our daily increasing Fauna another species of this
genus which I have received from Michigan. It likewise appears somewhat
allied to H. leucopus but has very distinctive characters in its colors.

H. GRACILIS.

Hair dark slate-color above, a little tipped with brown, cheeks, line above
the mouth, chin, throat and body beneath white, allowing the dark color of
ihe lower part of the hair to shine through in such a manner as to cause
these parts to appear grey. Outer side of fore legs brownish, thighs slate-
< olored both above and beneath, feet pale grey, nearly white. Head narrow, nose
somewhat pointed, ears large, open, narrowly edged with whitish. Tail longer
than the head and body.

Length 3.8 in. Tail 4 in. Head 1.2. Ears .6. Fore leg .1. Hind leg 1.5.

Inhabits Michigan ; Prof. Baird.

We have in this genus three species which resemble each other. I have added
below, short diagnostic marks by which they may be easily distinguished.

H. leucopus, supra laete badius, interdum prope aurantiacus, subtus niveus,
coloribus a se abrupte disjunctis, pedibus posticis anticis plus duplo longioribus.

H. cognatus, supra nigro-fuscescente, et fusco variegatus, subtus albidus
tanquam cinereo-mixtus, pedibus nontam imparibus.

H. gossypinus, supra fuscescente-badius, lateribus dilutioribus, subtus
cinerascente-albidus. Corporis magnitudine valde a duobus precedentibus differt.

Mr. Vaux, on behalf of a Committee appointed In 1852, to collect
funds for enlarging and improving the Hall, read the following Report : —

The Committee, as constituted by the Academy, September 2S, 1852, to solicit
subscriptions for the purpose of enlarging and altering the Hall, beg leave to
present the following Report : —

The amount originally esiimated as requisite for the contemplated improve-
ments was $6,500, which the Committee were soon enabled to announce to the
Society had been obtained. But before a contract had been closed for the
work, a great advance took place in the price of labor and materials. Other im-
portant alterations and additions also were proposed. A new estimate was then

44-8

[December,

made, greatly exceeding the first. The Committee continued their labors, and
they have now the pleasure to state in this, their final report, that their efforts
were crowned with success, and that the whole amount required for carrying
out the plan of the Building Committee, including the alterations referred to,
and others also which became necessary during the progress of the work, has
been subscribed, collected and paid over to the Treasurer.

y Committee.

1855.] 449

Mr. Vaux, on behalf of the Committee appointed January '25th, 1853,
to superintend the enlargement of the Hall of the Academy, presented a
final report, exhibiting the cost of the improvement, and its satisfactory
completion.

The original estimated cost of the work, $6,500, was increased to
$10,500, in consequence of an extension of the plan, and a great ad-
vance in the price of labor and materials. During the progress of the
work, other alterations and additions, which could not be foreseen
or provided for beforehand, were also determined on, at a cost of
$1,763 above the contract, making the whole expense $12,263, all
which had been received. A final settlement had been made with the
contractor during the present month.

The Librarian read the following Heport : —

REPORT OF THE LIBRARIAN FOR 1855.

Since the last Annual Meeting, in December, 1854, the additions to the Library
consist of 233 volumes, 561 periodicals and serials, 70 pamphlets, and 9 maps,
on the following subjects :

Natural Sciences, -
Anatomy and Physiology, -

Journals, Trans., Memoirs, and Proceed, of Societies "I
and Cyclopaedias, - - f

Physical Science and Chemistry, -
Voyages and Travels, -
History and Biography, -
Antiquities and the Fine Arts, -
Miscellaneous, -
Maps, 9

Making a total of 857 additions for 1855.

These have been derived from the following sources ;
Societies, Corporations and Governments 313 ; Members and Correspondents 46 ;
Dr. Wilson 410.

The inconveniences arising from insufficient accommodations for the books,
which have been alluded to in previous reports, happily no longer exist. The col-
lections which formerly occupied the room on the right of the George street en-
trance, have been removed to more appropriate places provided for them in the
upper Hall, and this fine apartment has been tastefully fitted up during the past
summer, and now forms part of the Library. It communicates directly with the
adjoining rooms, comprises an area of about 1400 square feet, has a gallery ex-
tending round it, and is furnished with cases which occupy the walls, and which,
it is estimated, will accommodate about 10,000 volumes.

There are now three distinct apartments occupied as a Library, all on the
basement floor, well lighted, and comprising togetheran area of upwards of 2400
square feet. A new arrangement of the Books has been made, which, it is
hoped, will afford increased facilities to those consulting them. The accommo-
dations for them are now ample for any ordinary increase for many years.

A favorable opportunity ha3 been afforded by this re-arrangement, for making
another enumeration of volumes possessed by the Society. These have been
found to number at this date over 15,000, distributed as follows :

There is also a very large collection of tracts, periodicals, serials, &c, which,
when bound into volumes, will doubtless swell the aggregate to 15500. The
first enumeration was made in December 1850. At that date the number in
the Library was 11,557, exclusive of 500 estimated volumes of tracts, &c. The
increase therefore in five years, has been about 3500, or an average annual in-
crease of nearly 700 volumes. By comparing the corresponding items in the two
statements for 1850 and 1855, it will be found that a very large proportion of the
whole increase is made up of works in the various departments of Natural
Science, in Anatomy and Physiology, and in the Journals or Periodicals, viz.,
1554 volumes on the Natural Sciences, 319 on Anatomy and Physiology, and
1029 Journals, or a total increase of upwards of 2900 volumes in these three
most valued and most frequently consulted departments of the Library.

In conclusion, we may add, that during the present year, as in many others,
the Library owes all that it has received to the relations the Academy has formed
with other scientific bodies, or to the generosity and liberality of its friends and
supporters. Respectfully submitted by

Wm. S. Zantzinger, Librarian.
December 25, 1855.

The Report of the Treasurer for 1855 was read and referred to the
Auditors.

Dr. Leidy read the following Report : —

REPORT OF THE CURATORS FOR 1855.

Since the last annual Report of the Curators was presented to the Academy,
the alterations and enlargement of the building, commenced in 1853, have been
completed. The character of the alterations it is unnecessary to give in this
place, as it is done in an especial report of the committee, which was appointed
to superintend the changes, and it is proposed here, merely to give a general
view of the present arrangement of the museum, now contained in two saloons ;
the one above the other.

The upper saloon of the museum is 110 feet long, 35 feet wide, and 34 feet
high; and it has three ranges of galleries extending completely round. Two
stairways communicate with this saloon, one on each side of the back or western
third, and they ascend in the same position to the upper gallery. On the floor
the side cases are brought out upon a line with the edge of the first galleiy, leav-
ing behind the cases, in advance and back of the stairways, four rooms, of which
the two longer are appropriated to the entomological and oological cabinets, and
the herbarium, and the others are appropriated to the services of the conchologi-
cal and mineralogical committees.

All the upright or wall cases of the upper museum saloon, with the exception
of four at the east end of the first gallery, numbering 169, are appropriated to
the ornithological collection, now in process of arrangement by Dr; Wilson.

The middle of the floor is occupied with 48 large, horizontal cases, arranged

1855.] 451

in twelve double rows, and accommodating the conchological collection, now
under arrangement.

The edge of the first and second galleries supports 62 horizontal cases, which
with four upright ones at the east end of the first gallery, contain the collection
of minerals, newly arranged by Messrs. Vaux and Ashmead.

The edge of the third gallery supports 27 horizontal cases, containing Crusta-
cea, and 13 cases of the same kind, containing echinodermata.

The lower museum saloon is of the same length and breadth as the upper one,
but is 11 feet less in height ; and it has two galleries extending entirely round,
except at the east end of the first range. A stair case for the admission of the
public, communicates with the hall in the south east corner, and in the same
position ascends to the second gallery. At the back third of the same gallery,
a stairway communicates with the saloon above ; and on the opposite side a
stairway ascends from the floor to the hall above, and communicates with the
library rooms below.

The north-east corner of the lower museum saloon, on the floor and at the
termination of the first gallery, is occupied by two small rooms, appropriated to
the service of the mammalogical and herpetological committees.

At the back third of the saloon, on the third floor, the side wall cases are
brought out on a line with the edge of the gallery, leaving behind the cases two
small room3, appropriated to the use of the committees on palaeontology and
ornithology.

In advance of the two rooms just mentioned, large glass cases extend nearly
two-thirds the length of the saloon, for the accommodation of the larger mam-
malia and skeletons. The floor in the interspace of these cases, is occupied
by three longitudinal double rows of partly horizontal and upright cases, 66 in
number, appropriated to the collection of extinct invertebrata, and of geological
specimens of rocks, yet unarranged.

In the east end of the saloon, there is one large, horizontal, transverse case,
and three upright wall cases, containing large specimens of extinct vertebrate
remains, the bulk of which collection, however, is now contained in three trans-
verse double rows, of partly horizontal and upright cases, 18 in number, and i^:
four wall cases to the north side of the latter, in the back third of the saloon.
The four upright cases opposite to those just indicated, together with four others
in the west end are appropriated to skeletons.

The wall cases on the northern side of the first gallery, 19 in number, ac-
commodate the collection of reptiles, and the corresponding cases on the oppo-
site side, 20 in number, contain the collection of human crania.

The edge of the first galiery supports 44 horizontal cases, containing the col-
lection of extinct vegetable remains, arranged by Mr. W. F. Rogers.

In the upper gallery, in advance of the stairways, there are 30 wall cases and
12 long foot cases at the edge of the galleries, appropriated to the mammalogical
collection ; and back of the stairways there are 14 wall cases and 6 foot cases,
to be appropriated to the collection of fishes.

On the two galleries at the west end, there are 8 vertical cases, and three
others at the side of the first landing of the stairway, in the south east corner,
to be used for the collection of sponges and corals.

The furnishing of the upper museum saloon and committee rooms, important
alterations in the lower museum saloon, and the construction of new cases in the
front basement room of the building, now appropriated to the use of the library,
have been effected without cost to the Academy ; the expense, amounting to
$10,850, having been defrayed by our liberal fellow member, Dr. T. B. Wilson.
In the alterations the old material was used wherever it could be done with ad-
vantage, so that they appear to be of greater magnitude than the expense
would allow.

During the year just about closing, the donations to the different departments
of the museum and the labors therein have been as follows : —

Mammals. — Of these animals there were presented 26 specimens of 18 species,
among which were a reindeer from Greenland, presented by Col. G. A. McCall ;

452 [December,

a second specimen of the same animal and two species of Phoca, presented by
Dr. Wilson ; and a third species of Phoca presented by Mr. Vaux.

Birds. — Mr. Guex presented 190 bird skins from Italy; and 24 specimens were
presented by J. D. Sergeant, Dr. Heermann, Mr. Krider and others.

The oological collection has been removed from the position it formerly oc-
cupied, and has been rearranged by Dr. Heermann, in cabinets of drawers, con-
structed for the purpose, and now located together with the entomological collec-
tion in the north east room of the upper museum hall.

Reptiles. — Of these animals, several hundred specimens of about 40 species,
have been presented by various members and others.

The collection of reptiles of the Academy, has recently been arranged by Dr.
Hallowell, who has devoted much time to its study.

of 26 species of fishes, from South America; Mr. Ashmead has presented 40
specimens of 24 species, from our coast ; and Dr. Burtt, U. S. N., has presented
a small collection from Madeira. Resides these, 28 specimens of 21 species have
been presented by various members, and 41 specimens of 22 species have been
received in exchange.

Mollusks. — Dr. Burtt, U. S. N., has contributed to the collection of the Acade-
my 98 specimens of 34 species of shells, from various parts of the world ; F. A.
Sauvalle, Esq., has presented 50 specimens of 16 genera of terrestrial and fiuvi-
atile shells of Cuba; and various members have presented numerous specimens
of 38 species, besides several small collections, in which the specimens were not
enumerated.

Insects. — Mr. Guex has enriched our entomological collection by a contribu-
tion of 2300 specimens of about 1800 species of coleoptera from Italy, Russia,
Siberia, Caucasus, Sitka, East Indies, and Australia. Mr. Andrew Murray of
Edinboro presented 50 specimens of African coleoptera; and several members
have contributed others in the various orders.

Crustaceans, arachnides, myriapods, annelides and zoophytes. — Of Crustacea 34
species have been presented, chiefly by Mr. Ashmead. Of arachnides 3 have
been presented ; of myriapods 6 ; of annelides 20, among which is one of Eunice
gigantea, from India, presented by Mr. Guillou ; of ecbinoderm3 12 ; of corals
4, among which is a fine specimen of Dendrophyllea ramea presented by Dr.,
Burtt, U. S. N., and one of the curious Hyalonema sieboldi, or glass-coral of
Japan, presented by Capt. H. A. Adams, U. S. N. ; aud of sponges 4 species.

The collection of Crustacea has been recently arranged to a considerable
extent, by Dr. Bridges.

Comparative Anatomy. Of skulls of different animals 27 have been presented,
of which 18 are from Dr. Heermann, and among the others is an ancient Mexican
skull, presented by Dr. E. H. Barton of New Orleans, and the skull of a Japa-
nese, presented by Dr. Liner, U. S. N. Of skeletons 4 small ones were presented,
and of miscellaneous specimens 12.

The collection of human crania, now numbering 1006, has lately been com-
pletely arranged, classified, and catalogued by Dr. J. A. Meigs.

Botany. A collection of plants from Japan, consisting of several hundred
specimens, was presented by Dr. Jos. Wilson, U. S. N. ; a collection of ferri3
from Africa by Dr. Burtt; and a collection of 29 species marine algae by Mr.
Ashmead. There were also 24 other specimens, generally consisting of seeds
and fruits presented by different members and others.

The herbarium of phanerogamous plants is now undergoing careful re-arrange-
ment by Mr. E. Durand ; and several of the members intend shortly to re-ar-
range the collection of cryptogamia.

Pal&ontology. A collection of fossils, consisting of 656 specimens of 280
species, from the coal measures, carboniferous limestone, devonian and Silurian
series of Great Britain and Ireland, was presented by Dr. T. B. Wilson ; Prof.
B. L. C. Wailes presented 38 species of shells and corals from the tertiary beds
of Mississippi, being the original specimens described by Mr. Conrad; and small
collections from different systems were presented by Dr. W. H. Hammond, U.

1855.]

453

S. A. ; Mr. Moore of Te xa3 ; J. Sampson of Indiana; and Dr. R. W. Gibbes
of South Carolina. Neatly 200 specimens of fossils were presented from var ici B
localities, by different members and others. Among them is a fragment of
wood weighing over 100 pounds from the drift of New Jersey, presented by Dr.
Camac.

Mineralogy. Chas. M. Wheailey, Esq. preeented 41 fine specimens of mine-
rals, principally from Chester Co. ; Dr. T. B. Wilson presented 218 specimens of
European rocks ; and Mr. W. S. Wilson presented a tablet containing 60 polished
specimens of marbles of the Pyrenees. Besides the foregoing, 71 specimens of
minerals were presented by various members and other persons.

The Museum of the Academy was re-opened to the public on the 1st of June,
as usual on Tuesday and Friday afternoons, from one o'clock uniil sundown ;
and since its re-opening the number of visitors has exceeded 7000, or an ave-
rage of over 1000 a month.
