OF PHILADELPHTA.

Art. I.—Notice of Producti found i the Western States and Territories, with descriptions
of twelve New Species. By J. C. Norwoop and Henry Prarten, of the Illinois

Geological Survey.

The genus Productus, established by Mr. Sowerby, in 1814, being found so abun-
dantly in the “mountain limestone,” of Europe, it was natural to suppose, that
when this formation, which is so extensively developed in our Western and Southern
States, came to be explored, it would yield many more species than it was known to
furnish when M. de Koninck published his admirable monograph on the Producti, in
1847. This expectation has, in some degree, been realized; twelve new species being
now added to the published catalogues of American and European paleontologists.

The wide distribution of this formation in North America, occupying, as it does,
extensive districts in the States of Kentucky, Indiana, Illinois, Missouri, Iowa, Ten-
nessee, Alabama, and Arkansas, together with Nebraska territory, as well as on the
Humboldt river, in Utah, we may reasonably expect that the present list will be
ereatly extended, especially when the State collections of Missouri, Ilinois and Ken-
tucky come to be examined and collated.

It is not, however, in the “mountain limestone” alone that the Producti are so
widely distributed. ‘The marine limestones and calcareous clays of the coal measures
are equally, if not still more, prolific in species of this genus. Many of the species
in the following list are found, exclusively, in that formation; and, with a few species
of other genera, are the most reliable indicators in the exploration of our Western
coal fields.

6 NORWOOD AND PRATTEN ON PRODUCTI.

In the Devonian limestones we have met with only two species, both of which are
also found in Europe. One of them, the P. Murchisonianus, it is certain, also belongs
to the upper Silurian rocks of Indiana. Several of the species described were found
by Mr. Pratten in the Western part of Missouri, and on the Nemahaw river, in Ne-
braska, in a limestone, the age of which has not been yet determined.

In the “Report on the Geology of Wisconsin, Iowa, and Minnesota,” Dr. D. D.
Owen mentions having found the P. marginalis. As we have not met with that
species, it is not included in the present catalogue. He also indicates several new
species from North-western localities, of which it is to be hoped he will before a
publish descriptions.

At the time M. de Koninck’s work was published, the whole number of species
known was sixty-two. Dr. D. D. Owen added one from the U. 8. Survey. We have
now added twelve, which makes the number of the species known, in all countries, up
to the present time, seventy-five. It may also be seen, by consulting M. de Koninck’s
work, that, at the time of publication (1847), the whole number of species known to
occur in the United States and Territories amounted only to seven.. They now num-
ber thirty, and the probability is, that future investigations will greatly extend the
catalogue.

For the beautiful and accurate drawings of the species now published, we are
entirely indebted to Mr. H. A. Ulffers, of the Illinois State Survey.

Kentucky. This beautiful Productus is very widely distributed in the Western
States. ;

P. ALTONENSIS, nob.—PI. I., fig. 1, a, 0. ¢.

Shell of a medium size, dorsal valve regularly vaulted and strongly curved on itself,
very much inflated, geniculated, anterior part flattened. Beak swollen, and passing
beyond the cardinal border. Surface covered with a great number of slender, filiform
ribs, which frequently bifurcate, while occasional new ones are implanted between
the old ones. This shell appears to have been rather irregular in its growth, for,
while some specimens are slightly transverse, others are a little longer than broad.
The sides are flattened, so as to fall almost perpendicularly on the ears, which are
small, and crossed by several undulating folds, as in the P. cora; they are, however,
sharper and more numerous than in that species. Two or three ranges of small
tubercles are placed on these folds. Some of the specimens show that there have
been ranges of tubes across the anterior portion of the shell, somewhat similar to
those on occasional specimens of the P. Flemingii. In addition to these, a few tubes
are scattered over the remainder of the surface.

The ventral valve is very regularly concave on the visceral portion, but becomes
more abruptly bent as it approaches the other valve, so as to follow it in its anterior
prolongment, which is, however, short. Its ribs are like those of the dorsal valve ;
the ears have a few folds, with slender tubercles, like those of the dorsal valve. The
visceral part is also crossed by several folds, which become very indistinct as they
approach the centre of the shell.

Dimensions.—Length, 25 millimetres; thickness, 9 millimetres. At the distance
of 20 millimetres from the beak, the ribs number 18 in the space of 10 millimetres.

Comparisons and Differences—This shell approaches more nearly to the P. cora,
in its general appearance, than any other species of the genus we have met with. It
may, however, be easily distinguished from that species by the greater regularity of
its ribs, which are not bent and contorted, as they are in the P. cora; by the size of
the ribs, which are larger in the P. Altonensis ; and by the greater number of small
tubercles with which its surface, especially the anterior part, is furnished. It is still
more distinctly marked by the lines of increment which cross the ribs on their ante-
rior prolongment, and give to that portion of the shell a reticulated appearance, par-
ticularly when seen through a lens. This characteristic is never met with in the P.
cora. From the P. Flemingii it may be easily distinguished by the absence of
a sinus, and by the non-reticulation of the visceral portion. It cannot be con-
founded with any other known species than those above mentioned.

Locality and Geological Position—Alton, Illinois, in the upper portion of the moun-
tain limestone series.

P. Paiturpsi, nob. PI. I., fig. 2, a, 8, ¢.

Shell rather small, nearly as long as broad, dorsal valve slightly gibbous, its ante-
rior part flattened, with a wide shallow sinus on old specimens, while young ones do
not show it. The beak, although slightly enrolled on itself, does not pass the cardinal
border. The ears are small, flattened and smooth, showing no trace of either folds
or tubes. The surface is covered with coarse, irregularly sized ribs, which are gene-
rally broader than the furrows separating them. Many of the ribs are bifurcated.
The cardinal line measures four-fifths of the greatest breadth of the shell. The sides
fall perpendicularly on the ears. The only traces of tubes are a few indistinct ones
on the flanks.

Ventral valve concave, with a very slight varix. The visceral disk has ribs similar
to those on the other valve; beyond the disk they are obliterated, the surface being
covered with nine or ten broad lamella, the edges of which are turned sharply
upward, presenting acute wavy ridges, which are continued on to the cardinal border
on each side.

Dimensions.—Length, 19 millimetres. Proportions—Length 100, breadth 100,
thickness .047.

Ribs.—Near the anterior border there are from eight to ten in the space of ten mil-
limetres, and number, altogether, about twenty-eight.

Comparisons and Differences—By the coarse irregular ribs of the dorsal valve, by
the visceral portion of the ventral valve possessing ribs, together with the broad,
ridged lamellee around it, this species may be easily distinguished from any other. It
does not appear to have possessed an anterior prolongment, as its present front is
without one, and is bounded by a sharp margin.

Geological Position and Locality— Mr. Pratten found this in Utah Territory, at the
“ Big Caiion” of Humboldt river. It occurs in the mountain limestone, associated
with P. semireticulatus of Martin, and the Spirifer tricornis of de Koninck. +

PRODUCTI UNDATI.

P. unpirEeRvs, de Koninck.—“ Fossils of Belgium.” PI. V., fig. 4, and Pl. XL, fig. 5.

Geological Position and Localities—In Belgium this shell belongs to the mountain
limestone series, while in this country we have found it only in the coal measures,
and as yet at only three localities, Caseyville, Illinois, and two places in Posey county,
Indiana. At Caseyville it occurs in a thick bed of limestone, overlying the five foot
seam of coal. [Illinois State Collection.

P. Rocrrsi.—nob. Pl. L., fig. 3, a, 0, c.

Shell of medium size; slightly transverse; dorsal valve very high and strongly
enrolled on itself; cardinal border equal to about four fifths of its greatest transverse
diameter; beak rather large, and passing beyond the cardinal border; ears but little
distinct from the dorsal vault. ‘The anterior part is flattened, and possesses a slight
sinus. The surface is covered with ribs, of which twelve may be counted in the space
of ten millimetres, at the distance of ten millimetres from the beak. It is also
covered in its whole extent with transverse folds. Those nearest the beak are rather
small, but, after passing the visceral disk they rapidly increase in size to near the middle
of the shell, after which they again decrease in size to the margin. The whole anterior
portion of the shell seems to have been pretty thickly covered with tubercles, especially
between the transverse bands, while a few were distributed over the remainder of the
surface. On the middle part of the shell there are only — transverse bands in the
space of ten millimetres.

Dimensions.—Length, 21 millimetres; breadth, 24 millimetres.

Comparisons and Differences.— Although we have only one specimen of this species,
and from this one the shell is abraded over the greater portion of its surface, still its
form and characteristics are so distinct that it cannot be confounded with any other.
The P. undatus comes nearest to it, but our species differs from the undatus in having
larger ribs, and flattened transverse bands, while the bands of the wndatus are sharp.
The P. Rogersii is further distinguished by having its anterior prolongment covered with
tubercles, some of which, judging from a few remaining fragments, must have been
of considerable length. Ventral valve unknown.

Geological Position and Locality—This specimen was found by Mr. Pratten in the
coal measures, near Huntsville, Missouri. It occurs in a bed of ferruginous limestone
overlying a stratum of bituminous shale.

Section III.
PRODUCTI PROBOSCIDEI.

Propuctus cLAvuS, nob.—PIl. I., fig. 4, a, 6, ¢.

This very singular shell is the only one of the class we have met with, and it is in
so imperfect a state of preservation that for some time we hesitated about including
it in the present notice. Like its Kuropean congeners, however, it is so rare, and so
remarkable in form, that we have concluded to figure it, and give such a description
as the mutilated specimen before us will admit of, in the hope of being able to furnish
a more complete one when we shall be so fortunate as to secure more perfect speci-
mens.

This species is small, longer than broad, the dorsal valve is divided into two very
distinctly marked parts, distinguished especially by the direction of the bands and
ribs. The visceral portion is slightly arched, and covered with well defined trans-
verse bands, separated by somewhat deep furrows, the furrows being ornamented by
delicate strize, having the same direction as the bands. The bands are about twenty
in number, and appear to reach, all of them, up to the cardinal border on both sides.
They are narrower towards the beak, and increase in width, although not regularly,
as they approach the front, some of them being more prominent than others. The
beak is small; pointed; shows no evidence of a median sinus; and appears to pass
little, if any, beyond the cardinal border.

The prolongment is cylindrical, and slightly contracted at its junction with the
visceral portion ; straight, and in the direction of the axis of the shell. It is covered
with broad, regular ribs, numbering about twenty in the space of ten millimetres.
The ribs of the prolongment can be traced on to the last fold of the visceral part,
giving it a reticulated appearance. Whether the prolongment was closed all round,
as in the P. proboscideus, or open on the ventral side, as in the P. genuinus, cannot
be decided from the imperfect specimen before us.

Dimensions.—Length of the visceral part, 11 millimetres; breadth the same.
Diameter of the prolongment, 7 millimetres; length of the part preserved equal to
that of the visceral portion.

Comparisons and Differences.—It differs from the P. proboscideus of Mr. de Verneuil
with which alone it can be confounded, in the longitudinal ribs not extending over
the visceral portion, and in the prolongment not showing the numerous and well-
marked transverse folds of that species. The longitudinal ribs of the proboscideus
are also much finer, numbering about fifty in the space of ten millimetres at the
anterior border of the visceral part. Our species shows no trace of a sinus.

Shell small, transverse, the cardinal edge being the widest part ; somewhat inflated ;
but with its visceral and anterior parts rather flattened. Ears very much extended,
each bearing, generally, two thick tubes, and are a little enrolled. The surface is

12 NORWOOD AND PRATTEN ON PRODUCTI. —

furnished with about thirty tolerably thick ribs. It is difficult to count them, how-
ever, in consequence of the shell, which is very thick, being formed of several layers,
which exfoliate easily. The beak is small, hardly passing the cardinal border. The
visceral part is reticulated by wide, shallow, concentric folds. The dorsal valve is
divided by a deep sinus. There are, generally, from six to eight thick tubes seattered
over the surface, three or four of which range across the shell in a tolerably straight
line, about half way between the visceral portion and the front line of the ventral
valve.

Ventral valve concave; ribs like those of the other valve, broad and but little
raised, while the shallowness of the furrows which separate them rendersit as difficult
to number them as those of the opposite valve. The visceral part is crossed by
irregular concentric lines. Although the ventral valve is concave over most of its
extent, yet, a little before it reaches the opposite one, it suddenly flattens, presenting
the appearance of a flat band, which passes around its anterior and lateral borders,
This band is a little over one millimetre in width, and is divided from the concavity
of the shell by a slightly raised ridge on its interior border. On the visceral portion
of the interior of the dorsal valve there is a strong middle projection, on each side of
which are the hepatic apophyses, deeply hollowed out in the substance of the shell ;
they are triangular, with their anterior part very much ramified. The remainder of
the fossil is covered with granular points, which leave corresponding hollows on the
internal mould when the shell is taken off.

Dimensions.—Length, 18 millimetres; width, measured along the cardinal border,
26 millimetres. The angle formed between the lateral and cardinal borders is 62°.
The whole number of ribs is thirty-two.

Comparisons and Differences—This species approaches, in many respects, to the
P. expansus of De Koninck. It may be easily distinguished from that species, how-
ever, by the following characters: the ears of the splendens are rounded, while,
according to de Koninck, those of the ezpansus are flattened,—it has several thick
tubes on the anterior prolongment, the ezpansus has none,—it has a very thick shell,
while that of the ezpansus is thin. When a detached ventral valve can be obtained,
the flat border around it will at once distinguish the splendens.

Geological Position and Locahties—This beautiful species occurs at Galatia, Illinois,
in the coal measures; six miles West of Richmond, Missouri, and near Big Creek,
Posey county, Indiana, in a black limestone belonging to the coal measures.

‘P. WABASHENSIS, 70b.—PI. L., fig. 6, a, 0, ¢, d.

Shell small, transverse ; dorsal valve gibbous, enrolled on itself; beak small, pointed,
and not passing the cardinal border. This valve is divided in its middle by a wide,
‘deep sinus. The surface is covered by about forty ribs, some of which, however, after
leaving the visceral part, unite, so as to form by their junction one thicker rib; but
this character is not constant, as some specimens possess it while others do not. The
ears are thin and enrolled; no tubes have yet been discovered on them. The car-
dinal border is of about the same breadth as the greatest transverse diameter of the
shell. On the surface of the shell itself there are, generally, from six to eight tubes,
very thick and long for the size of the shell, one, still attached, being over seven
millimetres long. The transverse folds on the visceral disk are wide and shallow, so
as to be hardly apparent.

The ventral valve is very concave, following nearly the movement of the opposite
valve; ribs like those of the dorsal, but it has neither tubes nor hollows. It is
furnished with a very decided varix, corresponding to the sinus of the dorsal valve.

Dimensions.—Length, 13 millimetres; breadth, 16 mm.; thickness, 6 mm.

Ribs.—Forty on the entire surface.

Comparisons and Differences—When this shell is entirely disengaged from the
rock, it cannot be mistaken for any other species; but when the dorsal valve only is
exposed, it may be confounded with the P. splendens ; but even then it may be easily
recognized by its much shorter cardinal border. If the specimen has lost its shell, the
ribs are still shown on the mould in this species, with a series of rounded hollows
along each furrow, between the ribs, while in the splendens the hollows are irregularly
distributed over the entire surface of the mould, without any appearance of ribs being
shown. The nacre of the shell is still very brilliant.

Geological Position and Locality—As yet this species has only been found near
New Harmony, Indiana, in the middle part of the Coal Measures.

P. ELEGANS, nob. PI. L., fig. 7, a, 0, ¢.

greatest breadth of the shell. ars small, and covered with a great number of small,
slender tubercles. ‘The surface of the shell is covered with rather large rounded ribs,
which regularly increase in size from the beak to the front in most specimens, while

4

on others they are found bifurcating, or with new ribs implanted between the old ores.
On the flanks of the shell the ribs are nearly obliterated, but a great number of small
spines are seen. A few small spines are, also, scattered over the remainder of the
surface. The visceral part is crossed by irregular folds, not so decided as the ribs,
but sufficiently well marked to give it a reticulated appearance. The remainder of
the surface is covered with fine undulating lines of growth. When the shell is
removed, a broad irregular furrow is seen passing round from the front to the ears on
each side, and separating the upper portion of the dorsal valve from its anterior pro-
longment.

Ventral valve very concave ; ribs like those on the dorsal valve, and crossed on the
visceral part by shallow concentric folds, a little better marked than those on the
opposite valve. ‘The visceral portion is distinctly limited by a large imbricated fold.
The ears and flanks are covered with tubercles, similar to those of the other valve.

Dimensions.—Length, 20 millimetres. Proportions.—Length, 1.00; breadth, 0.75;
thickness, 0.30.

Ribs.—On the margin of the transverse furrow, twelve may be counted in the space
of ten millimetres.

Comparisons and Differences.—This species resembles somewhat the P. fleaistria,
but may be distinguished from it by the visceral disk being reticulated, and by the
great number of small tubercles with which the surface, especially the flanks, are
garnished.

Geological Position and Localities. This species occurs abundantly in the Mountain
limestone at Chester, and at Kaskaskia, Illinois, and in Missouri, near Hat Island.

P. muRICATUS, (not of de Koninck or Phillips), nob. PI. I., fig. 8, a, b, c. d, e.

Shell small; transverse; dorsal valve tolerably regularly vaulted; surface covered
with ribs which are rather thick in comparison with the size of the shell. Cardinal
border nearly as long as the greatest width of the shell. ars thin and flattened,
with six tubes on each. Beak small; not passing the cardinal border. ‘The whole
surface is irregularly covered with spines, which project at right angles from the
surface of the shell. Visceral disk somewhat flattened and reticulated, the transverse
folds being more decided than the ribs themselves, which gives to that portion of the
fossil a rugose appearance.

Ventral valve concave; its ribs are mostly obliterated by the concentric folds on
the visceral portion, beyond which, however, they appear like those on the dorsal
valve. On the interior it has a bifid tooth, supported by a median ridge, which

NORWOOD AND PRATTEN ON PRODUCTI. 15

extends inwards to the centre of the valve. On each side of this are the hepatic
apophyses, small and triangular; by the sides of these are two depressions, and pro-
jecting forwards and laterally from these are two large callosities, bounded, anteriorly,
by a prominent ridge. On the anterior portion of the visceral disk are several long,
obtuse points, inclining forwards, posterior to which the surface is covered by other
shorter ones. In front, and along the sides of the visceral disk, are a great number
of points imbedded in the shell and looking forwards, but few of which rise above its
surface. From near the extremity of the tooth, at a short distance from the cardinal
border, proceeds, on each side, a strong and rather sharp ridge, running towards the
lateral angles of the shell, but increasing its distance from it as it recedes from the
tooth. Just before reaching the lateral edges it changes its direction, bends around
with them, and becomes lost, being absorbed by the shell. This ridge, with the front
of the shell, presents an oval outline.

Dimensions.—Length, 14 millimetres; breadth, 19 mil. Proportions.—Length,
100; breadth, 135; thickness, 0.42.

Ribs.—The whole number is from 22 to 24.

Comparisons and Differences—By the small number of ribs, the rugose appearance
of the visceral disk, and the great number of slender spines, with which its entire
surface is garnished, this Productus may be easily distinguished from any other known
species.

Geological Position and Locahties.—This fossil belongs to the coal measures, and is
found in the calcareous clays of that formation. It occurs at Fish-hook creek, Pike
county, Illinois, and six miles north-west of Richmond, Missouri.

P. PortLocK1anus, nob.—Pl. I., fig. 9, a, b, c.

Shell of a medium size; transverse; dorsal valve gibbous, much enrolled on itself,
and divided by a wide deep sinus, originating at a short distance from the beak, and
extending to the anterior border. Beak thick and short, not passing the cardinal
border. Cardinal border longer than the transverse diameter of the shell. Ears
rather long, rounded; follow, in a great degree, the vaulting of the dorsal valve;
covered with thick transverse folds; two or three tubes on each. Visceral disk large ;
a little flattened; crossed by very decided transverse folds, twice as large as the ribs

16 NORWOOD AND PRATTEN ON PRODUCTI.

which they decussate. Surface covered with large ribs, some of which bifurcate near
the visceral part; on the anterior portion they unite, two, three, and sometimes four,
uniting to form a broad flat surface; but after proceeding in this manner for a short
distance, they again separate. On these flat surfaces the striee of growth are well
marked. A few thick tubercles are scattered over the surface. Ventral valve un-
known.

Dimensions.—Length, 24 millimetres. Proportions.—Length, 1.00; breadth, 1.25.

Ribs.—On the anterior part, where the ribs are joined together, there are only five
in the space of ten millimetres; after they divide again there are ten in the same
space. On the visceral disk there are twelve in the same interval, crossed by six of
the transverse folds.

Comparisons and Differences.—This species approaches very nearly to the P.
costatus, but differs from it in several important particulars. The ears of the costatus
are sharply detached from the sides of the shell, while in the P. Portlockianus the
sides slope gradually down to the cardinal border, and follow in their contour the
vault of the dorsal valve. The cardinal border is also longer in our species; and the
angle formed by that portion of the shell and the lateral edges is only 85°, while in
the costatus it is 100°. It also differs in its ribs, none of which project beyond the
others, as they do in that species, but are all flattened alike on the anterior portion.
The transverse folds on the visceral portion are also broader than they are in the
costatus. Again, the sinus of the Portlockianus is much deeper and narrower than
that of the costatus. There is only one other species with which it could be con-
founded, the P. Boliviensts ; but it may be at once distinguished from that fossil by
the shape of its ears, which are, in the Boliviensis, more abruptly separated from the
sides than in any other known species of the genus; and by its beak passing far over
the cardinal border, while in the Portlockianus it scarcely overlooks it.

Geological Position and Localities.—We have only met with two specimens of this
species; one at Grayville, White county, Illinois, and the other at Charboniere, St.
Louis county, Missouri. They both occur in the coal measures.

Explanation of the Figures.—PIl. I1., fig. 9, a. View of the dorsal valve.

We ‘dedicate this species to Col. J. E. Portlock, of the Geological branch of the

Ordnance Survey of Ireland, who has done so much to elucidate the geology and
paleontology of that country.

P. PRaTTENIANUS, nob.—PI. L., fig. 10, a, 6, ¢, d.

Shell of medium size, transverse. When placed on its ventral valve, presents a
rectangular form. Cardinal line equal to the greatest breadth of the shell. The ears
are much extended, and garnished with a double row of tubes, very large in propor-
tion to the size of the shell; those nearest the cardinal border being directed back-
wards, and projecting far beyond the edge, while those in the second rank point 1m-
mediately upwards. The ears are covered with large folds. On the visceral portion
a few irregular undulations occur, none of which traverse it entirely. Dorsal valve
tolerably regularly arched; its anterior part flattened, sometimes depressed in the
middle, and then showing a wide, shallow sinus. The sides slope very gradually
down to the ears. The beak is small, rather pointed, and passes the cardinal border.
The surface is covered with a great number of longitudinal ribs, regular in form, and
increasing by the implantation of new ones. From twenty to thirty tubes are
scattered over the surface; the remains of which show them to have been very long
in proportion to the size of the shell. They all project from the shell at nearly right
. angles to their attachment, but, after proceeding a short distance, bend downwards.
The anterior prolongment is broken off on every specimen in our possession, with the
exception of a small fragment on the flank of one. This fragment passes about ten
millimetres beyond the visceral disk of the ventral valve.

Ventral valve concave, the visceral disk being divided from the ears by a very
large fold, with a deep hollow between this fold and the cardinal border. On this
valve there are neither tubercles nor hollows; its ribs are like those of the dorsal
valve. Outside of the visceral disk the shell is traversed by three or four wide
imbricated folds. On the interior of the ventral valve there is a small bifid tooth,
with a rounded hollow at its base, from which projects a very slender ridge, which
crosses about one third of the valve.

Dimensions.—Length, 20 millimetres. Comparison.—Length, 100; breadth, 130;

thickness, 0.35.
5

18 NORWOOD AND PRATTEN ON PRODUCTI.

Ribs.—At the distance of ten millimetres from the beak there are eighteen in -the
space of ten millimetres.

Relations and Differences.—This shell may be readily distinguished from the P.
Villiersi, to which it bears resemblance, by its visceral part being less enrolled ; in
having a more depressed form; in the great extent of its ears; in its beak being
smaller and more pointed; and in its tubes projecting more directly out from the
shell, instead of proceeding downwards in their attachment, as they do in the P.
Villierst.

Geological Position and Locality—This species is supposed to belong to the coal
measures; it is not, however, absolutely determined. It was obtained by Mr. H.
Pratten at the crossing of the Big Nemahaw river, about 85 miles a little North of
West from St. Joseph, Missouri.

Note.—It affords me great pleasure to be able to dedicate this new and beautiful
species to my friend and fellow laborer, Mr. H. Pratten; to whose quiet but fruitful
labors, for many years, several branches of science, besides geology, are largely
indebted. J.G.N.

P. HILpRETHIANUS, nob.—PI. L., fig. 11, a, 6, e.

Shell of medium size; depressed; transverse; subtriangular. Surface covered
with moderately-sized, rounded ribs, the furrows between which are wider than the
ribs themselves. The ribs are increased both by bifurcation and the implantation of
new ones. The front is flattened, with a very wide but shallow sinus. Beak small, -
pointed, passing beyond the cardinal border, which appears to have been short; in
the only specimen found, however, the cardinal border is unfortunately broken off, on
both sides, at about six millimetres from the beak, so that we have little of the ears
remaining. The sides fall almost perpendicularly on to the ears. The ears and
flanks are covered with a great number of small, slender tubercles. The whole sur-
face of the shell appears to have been covered with tubercles, which have fallen off,
in the specimen before us, leaving scarcely a mark of their place of attachment. We
infer, from this, that they fell off during the life of the animal, as it is difficult to see
the cicatrices without the aid of a good lens. There are no concentric folds; but the
entire surface is covered with fine undulating strize of growth. Anterior prolongment,
if any, unknown.

NORWOOD AND PRATTEN ON PRODUCTI. 19

On the ventral valve, the ribs appear to radiate from the beak. In the first part
of their course they frequently bifurcate ; afterwards few of them do so. ‘They go
on, however, regularly increasing in size, down to the margin; and are covered with
a great number of elongated tubes, lying closely down on the shell. This valve is a
little concave, with a slightly raised varix opposite the sinus of the dorsal valve.

Dimensions.—Length, 28 millimetres. Comparison.—Length, 100; breadth, 111;
thickness, 0.40.

Ribs.—At twenty millimetres from the beak there are ten in the space of ten mil-
limetres.

Comparison and Differences—We know of no Productus that can be confounded
with this species. Its flattened and triangular form, the greatest breadth being near
the front margin, from which it regularly decreases to the beak, as well as the great
number of spines on the ventral valve, will at once distinguish it from all others.

Geological Position and Locality.—It occurs in nodules of black limestone, imbedded
in a coal seam, at Charboniere, Missouri.

P. ALTERNATUS, nob. P). IL, fig. 1, a, 6, ¢, d, e.

Shell of medium size; length and breadth about the same. In young specimens
the dorsal valve is tolerably regularly arched, but is flattened on its anterior part,
without showing, however, any anterior prolongment; when old, it has a decided
anterior prolongment, proceeding at right angles from the visceral portion. The old
specimens have, also, a wide but shallow sinus. The surface is covered with wide,
flattened, transverse bands, placed one above the other, like tiles on a roof. These
bands are covered with spines, of which every eighth one reaches from the lower
edge of the band above to the lower edge of its own band. Midway between these
are other spines, which only reach half way up the band; and, between these again,
are others, which are only half the length of those last mentioned ; and, finally,
between the latter come out small tubes or. points, which are planted immediately on
the lower edge of the band. Some of these tubes are from five to eight millimetres
in length, and project downwards close tothe shell, forming a fringe around the lower
edge of each band. Beak small and passing beyond the cardinal border. Lars small
and a little enrolled.

Ventral valve almost unknown. We have only one specimen which shows any
portion of it, and that exhibits only a fraction of the internal surface. It is never-
theless, sufficient to show that this valve possessed bands like those of the dorsal
valve, that it followed all its movements, and that its visceral disk approached very
near to that of the other valve, there not being a distance of four millimetres between
them. Its internal surface is pitted with small hollows, corresponding to the tubes
of the dorsal valve.

Dimensions.—Length, 28 millimetres. Comparison.—lLength, 100; breadth, 100;
thickness, 0.14.

Bands.—On an old specimen the whole number of bands are fifteen. At ten mil-
limetres from the beak there are three bands in the space of ten millimetres.

Comparisons and Differences—This shell differs from the P. punctatus in being
smaller : in its broader and more regular bands; in the arrangement of the spines on
the bands; in its flattened anterior prolongment; and, especially, by the close
approximation of the two valves.

Geological Position and Locality.—Found in the mountain limestone, at Rocky run,
Hancock county, Illinois. Rare.

Art. Il.—WNotice of the genus CHONETES, as found in the Western States and Territories
with descriptions of eleven new species. By JoserpH G. Norwoop and Henry PRATTEN,
of the Hlinois Geological Survey.

This genus was established by FiscuEr in 1837, to separate from the genus Lepteena
such shells, having the same general form with those of DALMAN’S genus, as possess
a row of spines of the margin of the dorsal valve along the cardinal area. At that
time there were six species known. Up to the year 1843, other species were added
by European Geologists; and, in that year, our most distinguished paleontologist,
Professor HAut, described two from this country, C. cornuta and C. setigera, which he
united to the genus Strophomena of RArinEsquE. In 1847 M. pe Konincx published
his excellent Monograph on the genus, in which he not only enumerated, but described
every known species, amounting, in all, to twenty-three, including all those known in
this country. Since then, in 1852, Dr. D. D. Owen described a new species from
Missouri, making all the known published species, up to the present time, amount to
twenty-four. The two species already mentioned as described by Prof. Haut, belong
to New York; the third one, described by M. pe Konincx, the C. Shumardiana, is
from Kentucky, and named by him in honor of the zealous geologist and paleeontologist
who discovered it.

We now make known eleven new species from our Western States and Territories,
and announce the discovery of two others of the known species of Hurope in our western
formations, viz: C. armata, of M. BoucHarp, and C. Sarcinulata, of ScunorHEnt.

Six of these species were found at a single locality, the “Devils Backbone,” in
Tllinois, in limestone belonging to the Devonian period; one, two miles west of Jones-
boro, Illinois, in limestone of the same age; two, in the Mountain limestone of
Burlington, lowa; four are from the coal measures; and one, the Flemingii, is from a
formation, the age of which has not yet been determined, but which, probably, belongs
to the Coal period. It was found by Mr. Pratten ten miles northwest of Richmond,
Missouri.

The whole number of species known to M. pr Konincx, in 1847, 23

our country, four of which are common to the United States and Europe; and fifteen,
as at present known, peculiar to this continent. We must say, however, that there is
still another species, brought from the Humboldt river, in Utah, the markings of which
are too much obliterated to admit of its being described. It belongs to the Mountain
limestone, and is, from its form, evidently distinct from any other one of our species.
It was found by Mr. Pratten.

C. Surrut, nob.—PI. IL., fig. 2, a, 3, ¢.

Shell of medium size; transverse, having its greatest breadth on the cardinal border,
which is produced into points. Dorsal valve covered with numerous fine ribs, amounting
to about 160 on the margin. It is crossed by broad imbricated folds, marking the
successive periods of growth, and showing that its form was the same in all stages.
The entire surface is covered with small pits or hollows, as if from the falling off of
tubes or spines; these pits are tolerably regularly disposed in quincunx; they are
always on the summit of the ribs, and are larger and altogether different in shape
from the hollows at the bottom of the furrows between the ribs; these latter being
merely fine lines as if drawn by the most delicate graver. It has a wide shallow sinus,
which originates at the beak, and goes on increasing in breadth to the front. The
area is very large and formed by both valves ; the portion belonging to the dorsal valve
being hollowed, while that of the ventral valve is flattened. The deltoid aperture is
wide but nearly filled by the tooth of the ventral valve. Lars distinctly separated
from the dorsal vault by a wide depression. The cardinal edge has ten tubes on each
side of the beak. The ornaments of the ventral valve are like those of the opposite
one. On the internal surface of the ventral valve there is a bifid median tooth resting
in a socket, and supported by five ridges projecting into the shell, the two largest of
which are nearly parallel to the cardinal border; at a small distance from it, the cen-
tral ridge projects about two fifths across the valve; on each side of this are two others
supporting a series of points. All the interior surface, but particularly towards the
front, is covered with small points.

C. Fiscnert.—nob.—Pl. IL., fig. 3.

Shell of medium size; transverse, having its greatest breadth at about one third the
distance between the cardinal border and the front margin. Dorsal valve slightly but
regularly convex. ars not separated by a depression from the dorsal vault. It has
no ribs, properly so called, but in place of them the surface is covered with an innu-
merable quantity of extremely fine strie, which radiate from the beak. These striz
are crossed by concentric ones equally fine, giving it the appearance of fine net work.
There are five long thick tubes on each side of the beak, which project in nearly
straight lines backwards from the shell.

Area and ventral valve unknown.

Dimensions.—Length, 20 millimetres; breadth, 30.

Geological Position and Locality —This shell occurs at Burlington, Iowa, in beds
which are considered to be at the base of the mountain limestone. It is named in
honor of the founder of the genus. Illinois State Collection.

Explanation of the Figure.—P1. IL. fig. 3. View of the dorsal valve.

C. Lirron1, nob.—PI. II., fig. 4, a, 0, ¢.

Shell small; slightly transverse, having its greatest breadth near one third of the
distance from the cardinal border to the front margin. Dorsal valve very convex and
furnished with remarkably fine ribs, which number about 120 on the margin. Area
contracted and hollowed out of both valves; deltoid aperture very narrow. On the
cardinal edge we can see the traces of tubes without being able to count them. Ven-
tral valve very concave, leaving but a small space for the lodgment of the animal.
Ribs like those of the other valve.

Dimenstons.—Length, 15 millimetres; breadth, 20.

Geological Position and Locality—This species occurs at the Devil’s Backbone,
Illinois, in Devonian limestone. Dedicated to Prof. A. Litton, of St. Louis, Missouri.

C. Fiemineu, ob.—PIl. IL., fig. 5, a, b, c, d, e.

Shell rather small; depressed; transverse, having its greatest breadth on the car-
dinal border. Dorsal valve covered with a great number of slender, filiform ribs,
which frequently bifurcate and amount, when they reach the free borders of the shell,
to about 150. It is provided with a tolerably deep and wide sinus. The area is
formed at the expense of both valves. Deltoid aperture rather wide. LHars some-
what flattened, and separated from the dorsal vault by a very decided depression.
Cardinal edge ornamented by seven tubes on each side of the beak, which are directed
obliquely. In the furrows between the ribs are numerous shallow depressions, as
represented in the magnified view of a portion of the shell, Pl. IL, fig. 6,¢. The
ventral valve is furnished with a varix, corresponding to the sinus of the opposite
one. Its ribs are like those of the other valve, but become obliterated on the ears.

Internal part of the dorsal valve—There is a strong ridge projecting from the
beak towards the middle of the shell; on each side of which there is a large and
deep depression. Most of the remaining surface is covered with large granulations,
which, however, stop short of the free margin of the shell. Around this may be
seen a series of ribs corresponding to the furrows between the exterior ribs, and
showing a series of fine granulations, which answer to the small depressions of the
exterior. ,

Dimensions.—Length, 10 millimetres ; breadth, 17.

Geological Position and Locality—It is found in beds of shale, ten miles North
West of Richmond, Missouri. The age of the beds has not yet been determined.

C. VERNEUILIANA, nob.—PI. II., fig. 6, a, 6, ¢.

This is one of the most singular species of the genus. It is small, transverse,
having its greatest breadth on the cardinal border. Its beak is much larger and
higher than that of any of our other Chonetes. An extremely deep sinus extends
from the beak, bordered on each side by a high ridge; outside of which there is
another sinus separating the ridges from the ears, which are a little rounded and
much extended. Its surface is covered with about 100 ribs, very fine and dichoto-
mous. Area tolerably large, and formed at the expense of both valves. Deltoid
aperture very wide. Cardinal edge with four tubes on each ear, directed obliquely.
The ventral valve is furnished with a very decided varix, corresponding to the sinus
of the opposite valve. Its ribs are like those of the dorsal valve. .

Dimensions.—Length, 7 millimetres; breadth, 12.

NORWOOD AND PRATTEN ON CHONETES.

Comparisons and Differences—The depth of the sinus and the height of the ridges
alongside of it, will at once distinguish it from all other species. It is true that,
while young, it may be mistaken for the C. Flemingii; but even then its sinus is
deeper than in that species, and it has only four spines on the cardinal edge on each
side of the beak, while the Flemingti has seven.

Geological Position and Locality—This species occurs at Charboniere, Missouri, in
the calcareous clays of the coal measures. We dedicate this species to M. de Verneuil.
It will at once recall to every one the Productus, which bears his name, as they are
both possessed of a remarkably deep sinus. Illinois State Collection.

C. MESOLOBA, nob.—PI. II., fig. 7, a, 6, ¢.

Shell small; transverse, sub-rectangular. Dorsal valve covered with extremely
fine ribs, which, on the margin, number 150. They are everywhere crossed by
equally fine concentric stris. This valve is furnished with a very wide median sinus, ~
originating near the beak, from which it goes on increasing in width to the front
margin. From the bottom of this sinus rises a rounded fold of the same shape as
the sinus itself; that is, it is pomted towards the beak, widening from thence to the
front, so that its outline is triangular, the base being at the front of the shell. ars
small, and separated from the dorsal vault by a well marked depression, giving to the
front of the shell the appearance of being formed of three lobes, separated from one
another by the median sinus. Area rather large, and formed from both valves.
Deltoid aperture nearly closed by the tooth of the ventral valve. The cardinal edge
bears seven oblique spines on each side of the beak.

Ventral Valve——Its ribs are like those of the other valve. It has a well defined
middle sinus corresponding to the raised fold of the dorsal valve. On each side of
this sinus it has a sharp fold opposite to the bottom of the sinus of that valve.

Dimensions.—Length, 8 millimetres ; breadth, 11.

Comparisons and Differences.—At present there is no species of Chonetes known,
with which this one can be confounded ; no other one having a medial fold rising from
the bottom of the sinus of the dorsal valve. .

Geological Position and Locality.—This species occurs in the limestones and shales
of the coal measures; at Belleville, Illinois; and at Charboniere, Missouri. Llinois

C. Macturza, nob.—PI. II., fig. 8, a, 6, c.

Shell somewhat large ; depressed; transverse, having its greatest breadth near its
middle. At five millimetres from the beak the ribs number about thirty ; at one third
of the distance from the beak to the margin, most of them bifurcate. Between this
and the margin several of them divide again, and when they reach it, they number
about one hundred. The furrows between the ribs are of the same size as the ribs
themselves. On the internal mould of the dorsal valve, the central furrow is larger
than those on the right and left of it, evidently caused by a median tooth, which,
commencing at the cardinal edge, traverses more than two-thirds of the length of the
shell. On each side of the beak there are eight spines, directed obliquely. The ven-
tral valve is slightly concave. Its surface is similar to that of the opposite one.

Dimensions.—Length, 22 millimetres; breadth, 32. ;

Geological Position and Locality.—This species was found at the “ Devil’s Backbone,”
Illinois, in limestones of the Devonian period. Illinois State Collection.

We have great satisfaction in being able to dedicate this beautiful species to the
memory of William Maclure, the munificent patron of science, and the father of
American geology.

ture small, open; the tooth of the ventral valve fitting into it and partially filling
the aperture. The dorsal valve is but slightly convex ; the ventral valve is still more

slightly concave, leaving but a very small space for the lodgment of the animal. The
cardinal edge has six tubes on each side of the beak. Its surface is covered with rather
large ribs, which become nearly obliterated on the ears. The ears are small and
somewhat flattened. At the distance of five millimetres from the beak there are 12
ribs in the space of five millimetres, and the same number in the same space on the
margin ; they are fourteen in number when they leave the beak, but increase by bi-
furcation, so that when they arrive at the margin there are nearly sixty.

Ventral valve.—lts ribs are in all respects like those of the dorsal valve.

C. Martini, nob.—PI. IL, fig. 10, a, 0, ©.

Shell of medium size; depressed ; transverse ; sub-quadrangular ; the cardinal border
being, in a slight degree, the broadest portion of the shell. Dorsal valve somewhat
convex, and covered with tolerably large ribs, which bifurcate two or three times
before attaining the margin, where the whole number amounts to eighty. It has a
wide but shallow sinus, which originates near the beak, and gradually widens as it
proceeds towards the front. Lars flattened. Areaunknown. The cardinal edge has
eight thick blunt tubes on each side of the beak.

The ribs of the ventral valve are like those of the opposite one. On its internal
surface it has a cardinal tooth supported on four plates, which project inwardly, and
appear to be formed by the union of several ribs. The two plates nearest the cardinal
edge are much the largest. The internal ribs, which correspond to the external fur-
rows, show a series of granulations, but they are farther apart than in most of the
species of the genus.

Dimensions.—Length, 22 millimetres; breadth, 25.

Ftibs.—There are, on the margin, eleven in the space of five millimetres.

Comparisons and Differences.—This species differs from the C. Maclurea in its more
quadrangular shape, in the smaller number of its ribs, and in the possession of a sinus,
(that species having none.) From the Zuomyi it differs in its sinus, in the greater
number of its ribs, and in having eight tubes on each side of the beak, while the
Tuomyt has but six.

Geological Position and Locality.—This species occurs in the Devonian limestones of
the Devil’s Backbone, Illinois. TIlinois State Collection.

C. Kowincxtana, nob.—PI. IL, fig. 11, a, 6.

Shell small; depressed; transverse, having its greatest breadth on the cardinal line.
Dorsal valve slightly convex ; no sinus; covered, with the exception of its ears, with
fine dichotomous ribs, numbering twenty-two near the beak, and fifty on the margin.
The furrows between the ribs are of about the same size as the ribs themselves. Ears
flattened; and without ribs. Area unknown. The cardinal edge has two spines on
each side of the beak, placed near the extremities, which project slightly from the
edge and then turn downwards, and run nearly parallel with it. The lower ones,
which appear like a continuation of the edge, project three-tenths of an inch beyond
it.. Ventral valve concave, leaving a very small space for the lodgment of the animal.
Its ribs are like those of the dorsal valve.

Dimensions.—Length, 11 millimetres; breadth 17.

Ribs.—At the margin there are sixteen in the space of five millimetres.

Comparisons and Differences.—T his species can, on account of the length and peculiar
direction of its spines, not be confounded with any other.

Geological Position and Locality.—It occurs in Devonian limestone, two miles west
of Jonesboro’, Union county, Illinois. Llinois State Collection.

This very curious species is named in honor of M. de Koninck, whose admirable
“‘ Monograph” on the genus is known and appreciated by every geologist.

C. Logant, nob.—PI. IL., fig. 12, a, 6, ¢.

Shell small; transverse; having its greatest breadth near the cardinal border.
Dorsal valve inflated ; without a sinus; covered with about thirty rugose ribs. Ears
small, and scarcely separated from the dorsal vault. Beak rather large and recurved.
Ribs flattened, and crossed by fine lines. Many of them are dichotomous. Area and
ventral valve unknown. ‘Traces of tubes can be seen on the cardinal edge, but the
number cannot be ascertained.

Dimensions.—Length, 6 millimetres; breadth, 9.

Comparisons and Difjerences.—This species differs from the C. minuta of Goldfuss
(sp.,) in the number of its ribs, that species having but twenty-two while ours has
thirty. In other respects it resembles it.

Geological Position and Locality.—This fossil is found at Burlington, Iowa, in the
middle portion of the mountain limestone series. TIlinois State Collection.

Gen. Remarks.—This serpent has the general characters of coronella, but the nos-
trils open between the anterior frontal and nasal plates, instead of the nasal and in-
ternasal, the two being fused into one plate. We have, therefore proposed 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.*

Sp. char.—Head depressed, of moderate size; snout rounded; nostrils between two
nasals ; a frenal, more or less quadrilateral; one antocular; two posterior oculars, the
superior the larger; nine superior labials, the inferior margin of the eye resting on the
fifth and sixth; neck contracted ; body slender, thicker in the middle, with seventeen
rows of scales, the four or five inferior rows for the most part smooth, the rest very
slightly carinated; tail of moderate length.

Coloration—This serpent is very remarkable for its beauty; the ground color of
each scale is a deep slate color, with a yellow longitudinal line in the middle, not
extending the whole length of the scale; the anterior and posterior borders of each
scale bordered with light blue; under surface straw color. Abdom. scut. 148; 1 pre-
abdom. scut., bifid; 75 subcaudal.

Dimensions.—Length of head, 1 inch; greatest breadth, + inch; length of body, 18
inches; circumference at middle, 2 inches; length of tail, 82 inches.

Habitat.—Honduras, Central America. This specimen was recently brought from
Honduras by my friend Dr. Samuel Woodhouse. One is at once struck with the
beauty of this serpent. In its general appearance it resembles somewhat the Zamenis
viridi-flavus, of which we have a very fine specimen in the Academy, found by me
in the Pyrenees,—but their great dissimilarity is readily observed on placing the
animals in juxtaposition. The markings of the head and sides are altogether
different ; in viridi-flavus the eye rests upon the fourth and fifth labials, and not upon
the fifth and sixth, but the number of plates about the head is nearly the same, and
there is no great variation in the form.

vertical scute very broad, rhombic, the posterior frontals extended as far as the eyes;
supraciliaries small; loral plate oblong, taking the place of the anterior orbitar; trunk
cylindrical; tail acute. (Boie.)

ELAPOIDIs FASCIATUS, nob. PI. IV. |

Char—Two rows of teeth in the upper jaw, one in the lower; two anterior and
two posterior frontals, the former very much smaller than the posterior; a vertical,
pentagonal broad and short; two small supra-oculars; two occipitals ; nostrils between

Dimensions.—Length of head, $ inch; of body, 7 inches; of tail, 2% inches; total
length, 9% inches.

Habitat—Honduras. Two specimens, presented by Amory Edwards, Esq.

Gen. Remarks.—But one species of Elapoidis has heretofore been described, viz. :
Hlapoidis fuscus, Boie, a native of Java.

ELAPS, Schneider.

ELAPS ZONATUS, nob.

Char.—Anterior frontals much smaller than posterior; vertical short and broad ;
nostrils between two plates; a small loral; one ant-orbitar; two post-orbitars; five
superior labials, the eyes resting on the third and fourth; eyes latero-superior; pupil

a white band posteriorly; thirty-eight black rings and thirty-seven white, the black
rings measuring upon the sides 2 inch, the white +; upon the back and abdomen the
dimensions of the white rings are somewhat greater; the white rings upon the sides
each dotted with small black spots; seven black bands upon the tail; fifteen rows of
smooth quadrangular scales. Abdom. scut. 189; pre and post-abdom. scut. one of

Sciences, by Dr. Woodhouse.

ELAPS DIVARICATUS, 700.

Char.—Nothing remarkable about the plates of the head, except that the vertical
is somewhat prolonged ; a loral reaching to the orbit ; two post-orbitars; seven superior
labials, the eye resting on the third and fourth; nostrils between two plates ; head
narrow, depressed about half an inch in length; fifteen rows of smooth rhomboidal

band; thirteen crimson rings, from five-eighths to six-eighths of an inch in length,
and as many black ones about three-eighths of an inch, the latter bordered each with
a narrow ring of white; the red rings occupy about eight and a half rows of scales,
the black three and two half rows, and the white one and a half rows of scales; the
dark-colored white margined rings are therefore much. less, and the intermediate
crimson ones much more extended than in EH. fulvius, and hence the name divaricatus —
which I have given it; four black and three white rings upon the tail, the yellow
about half the length of the black, intermediate red spaces without dots.

Dimensions.—Length of head, 4 inch; breadth, 3’, inch ; length of body, 16 inches ;
of tail, 28 inches; circumference, .1 inch.

Habitat—Honduras. A single specimen, presented to the Museum of the Acad.
Nat. Sciences, by Amory Edwards, Esq.

Corytheolus vittatus 9, Kaup; Iguana tuberculata, Laurenti; and Cyclura denticulata,
Wieg., from Nicaragua, and a young undetermined species of Crotalus, from Mr.
Edwards.

ARGEMONE wmunita, nova species. Caulis erectus ramosus, 22-pedalis. Tota
planta glaucissima tenera et, maxime in ramis foliorumque marginibus, aculeis albis
retrorsis horrens. Folia subamplexicaulia, elongato-cordata, valde repando-sinuata
undulata. Flores in apicibus 3-4 conferti, breviter divaricateque pedunculati.
Calyx 3-sepalus caducus setosus, quoque sepalo cornuto, cornu in aculeum validum
desinente. Corolla 6-petala maxima, 5-4’ diametro; petalis cuneato-obovatis, mar-
gine denticulatis, albis recte venosis. Germen lanceolato-cylindricum, aculeis rectis
dense obtectum. Capsula adhuc ignota.

Stem branching, about 22 feet high. The whole plant very glaucous and, chiefly
on the stems and margins of the leaves, densely covered with strong and slightly
retrorse prickles. Leaves subclasping, elongate-cordate, deeply repando-sinuate and
undulate. Flowers in clusters of 3-4 on short divaricate peduncles. Calyx 3-sepa-
lous, prickly, each sepal bearing a horn terminating in a strong prickle. Corolla 3—4’’
in diameter ; petals six, white, veined, with slightly denticulate margins. Germ lan-
ceolate, cylindrical, densely covered with erect prickles. Capsule unknown.

The specimens submitted to our examination are incomplete and not sufficiently
advanced to determine the shape of the mature capsule and seeds. We have com-
pared it with various forms of A. mexicana and with the figure of Lindley’s A. gran-
diflora in Bot. Reg. T. 1264. If the latter and our plant are but varieties of A. meai-
cana, as Prof. Asa Gray thinks, they are two extreme forms of this very variable
species, the one being almost unarmed and the other densely prickly. Both Lindley’s
and our plant bear large and beautiful white flowers; but-in ours the texture
is more delicate than in the mexicana, and the habitus of the leaves and branches is
less acute, more rounded and undulating; the peduncles are shorter, stouter and
more divaricate. It grows in large patches at Williamson’s Pass and was in full bloom
in August and September.

COMPOSIT i.

CORETHROGYNE tomentetia, Torr. & Gray’s Fl., Vol. ii., p. 99. In some of
our specimens with inflorescence much developed, a very striking appearance is pro-
duced by the very dense and white tomentum being abruptly replaced by a green
glandular and viscous pubescence on the whole inflorescence. Leaves on the lower
part of the branches linear-oblong, appressed and closely sessile; those of the top of
the stem broadly obovate obtuse; those of the branches small and _bract-like.

GUTTIERREZIA micropuyiia, Gray. Pl. Fendl. p. 74, adn. Brachyris microce-
phala, D. C. Prodr. vol. v., p. 313. The inflorescence of our specimens being much
advanced, we were long deceived by the almost cylindrical and loosely turbinate
character of the heads of flowers which, in the genus Guttierrezia, are always more or
less ovoid. Tejon Valley, September.

Europe and presenting a corymbose summit densely set with filiform, erect, obtuse
leaves, 1-14” long, and crowded yellow heads of flowers. ‘The lower branches are
almost naked, rugose with a cracked epidermis; the upper branches, as well as the
leaves, with an aphthose-glandular resinous surface, emitting a strong smell of
fir balsam. The internodes are navicularly depressed below each axil and cos-

pendix. The sub-opercle is iong and nearly of the same breadth throughout. The inter-
opercle is large ; the cheeks are protected by small scales, and the opercular bones by
large, but the top of the head is smooth. The mouth is small; the posterior extremity
of the upper jaw not reaching to the orbit. The lower jaw, and intermaxillary bones are
armed, with two or three series of teeth, small, pointed, and closely set, with an outer
row of larger teeth; these teeth are all similar in form to those of the last described
animal, but are more minute; the vomer is furnished with a broad, and arrow-headed
eroup of very fine teeth, and the pharyngeal bones with paved teeth, with a border
of closely set, sharp pointed teeth below ; and the upper pharyngeal with similar teeth
in front.

The dorsal fin is long, elevated, and begins on a line with the posterior part of the
origin of the pectoral, and has ten spines, the two anterior short, the others long: it has
ten branched rays, more elevated than the spines. The pectoral is very long and
somewhat falciform in shape; it begins on a line with the posterior margin of the
bony opercle and extends beyond the root of the third anal spine, and has fourteen
soft rays. The ventral begins back of the origin of the pectoral and ends behind the
vent, near the anterior anal spine. The anal fin arises opposite the root of the tenth
dorsal spine, or slightly behind it, and terminates with the dorsal fin behind; it has
three spines, the anterior short, the others long and stout, with nine long branched
rays. The caudal is large, full, lunate behind and has seventeen rays.

The scales are small, somewhat unguiform, straight before, rounded and ciliated
behind, and longest in the horizontal direction. The lateral line corresponds to the
arch of the back, and runs parallel with it.

Description. This small Pomotis is so very convex, both at the dorsal and ventral
outline, as to have a sub-round form; it is compressed, though thicker below than
above. ‘The head is large, the snout is full, rounded, and is as broad as the occiput,
or the space between the eyes. ‘The eye is of a moderate size, and is placed at less
than one diameter of its orbit from the snout, and at one diameter and a half from
the bony opercle, with its lower margin near the middle plane of the head. The
posterior nostril is very near the orbit, and is above the median plane of the eye; the
anterior is very small.

The pre-opercle is rounded and slightly serrated at its angle. The opercle is large,
broad in front, and with a truncated angle behind, furnished with a broad, fleshy
appendix. The sub-opercle is large, and broadest in front; the inter-opercle is
also broad, and rounded below. The cheeks and opercular bones are covered with
large scales, but the top of the head is smoooth. The mouth is very small, the pos-
terior extremity of the upper jaw extending only to the orbit. The lower jaw and
the intermaxillary bones are armed with several series of delicate, pointed, recurved,
card-like teeth ; those of the outer row are the largest; there is a small, arrow-headed
patch of minute teeth in the vomer. The pharyngeal bones are furnished with
small, pointed straight, closely set teeth, and with a few of a larger size near their
internal margin.

The dorsal fin is long and elevated ; it begins at the opercle and extends nearly to
the root of the caudal, and has nine delicate spines and twelve branched rays. The
pectoral arises under the apex of the opercle, terminates at the vent, and has twelve
rays. ‘The ventral begins on a line with the anterior fourth of the pectoral, extends
to the first anal spine, and has one spine, and five soft rays; the anterior slightly
prolonged. The anal fin extends from the third dorsal soft ray, to the root of the
caudal ; it has three stout spines, the first short, the third longest, and ten branched
rays. The caudal is large, slightly lunate behind, and has seventeen rays.

The scales are large, most extensive vertically, nearly straight before, rounded and
ciliated behind. The lateral line runs near the upper fourth of the body and parallel
to the arch of the back, as far as the end of the dorsal fin, and then descends to the
median plane.

Description. This beautiful little fish is nearly elliptical in form, with both its
ventral and dorsal outlines strongly arched. The head is flat, broad between the
orbits, with the snout round and broad for the size of the head, and having several pores.
The eye is very large, and is placed one diameter of its orbit from the snout, one
diameter and a half from the extremity of the opercle, with its lower margin about
the median plane of the head, and its upper near the facial outline, though it does not
encroach upon it. The nostrils are large ; the posterior and larger, is very near the
orbit.

The pre-opercle is short and scarcely rounded at its angle. The opercle is large,
with its broad base in front and its apex behind truncated and furnished with a fleshy
appendix. The sub-opercle is:very narrow, but the inter-opercle is broad. These
bones, as well as the cheeks, are covered with scales, but the head above smooth. The
mouth is very small, the posterior extremity of the upper jaw not reaching to the
orbit. The lower jaw and intermaxillary bones are armed with a row of slender,
conical, sharp-pointed, recurved teeth, and within this, is a small patch of minute,
villiform teeth. ‘The vomer and palate bones are also furnished with small groups
of similar minute teeth. The pharyngeal bones are covered with paved teeth of
different sizes.

The dorsal fin is long and very much elevated ; it begins just behind the opercle,
terminates at the caudal fin, and has nine spines, with twelve long branched rays.
The pectoral is long and has ten rays. The ventral arises nearly with the pec-
toral, and ends with it behind; it is much elevated and has three spines and eleven
soft rays. The caudal is full, slightly rounded, and has seventeen rays.

The scales are small, unguiform, though very convex behind and broadest in the
vertical direction. The lateral line runs about the superior fourth of the body,
and is concurrent with the dorsal arch, to the end of the root of the dorsal fin, when
it descends to the median plane.

Description. This beautiful little fish is like the last described animal, elliptical
in form, arched both at the dorsal and ventral outline, although rather less so at the
latter. The head is small, short, with the snout narrow, though rounded, the occiput
broad, and there is no contraction between the orbits. The eye is large; it is placed
one diameter of its orbit from the snout, two diameters from the angle of the opercle,
with its lower margin at the median plane of the head, and its upper nearly half a
diameter of the orbit from the facial outline. The nostrils are on a line within the
orbit ; the posterior and larger is very near the orbit, and the anterior midway between
it and the snout.

The pre-opercle is short,rand scarcely, if at all rounded at its angle. The opercle
is small, subtriangular, its apex behind and furnished with a slight fold of skin. The
sub-opercle is large and nearly of the same breadth throughout. The inter-opercle is
also large, and all are covered with scales, though the top of the head is smooth. The
mouth is very small; the lower jaw, and intermaxillary bones are armed with numerous,
‘minute, villiform teeth ; the vomer, and palate bones have similar teeth, but smaller.

The dorsal fin is long and much elevated, especially in its soft portion; it begins
about the anterior fourth of the pectoral, or rather before it, and ends at the root of
the caudal; it has nine spines, and eleven branched rays. The pectoral arises ina line
vertical with the end of the opercle, and extends to the anal fin ; it has fourteen rays.
The ventral begins nearly in a line with the pectoral, and extends as far back ; it has
one spine, and five branched rays. The anal fin begins opposite the root of the second
soft dorsal ray, extends to the caudal, and is full and rounded like the dorsal fin ; it
has three spines and ten branched rays. The caudal is large and rounded slightly; —
it has seventeen rays.

The scales are large, rounded and ciliated behind, and nearly straight before. The

Descrietion. This fish approaches in its general form the Pomotis vulgaris, though
it is longer and less elevated, and is thicker, especially in front of the dorsal fin.
The head is large, and though narrow between the eyes has asnout full and rounded.
The eye is large and is placed one diameter of its orbit from the snout, and rather
more than two diameters from the extremity of the opercle, with its superior margin
at the facial line, and its inferior rather above the middle plane of the head. The
posterior nostril is oval, near the eye and about its median plane; the anterior is
smaller, round and midway between the eye and the snout.

The pre-opercle is rounded at the angle, with its ascending border nearly vertical.
The opercle is triangular, with its basis in front, its apex behind, rounded and furnished
with a very short fleshy appendix.

The sub-opercle is of nearly the same breadth throughout; the inter-opercle is
broad, and both are covered with large scales, but the cheeks and opercles have small

scales, and the top of the head is smooth. The mouth is large; the posterior ex-

tremity of the upper jaw reaching to the middle of the orbit; the lower jaw is the
the larger, and makes part of the facial outline when the mouth is closed. The lower
jaw and the intermaxillary bones are armed with small, pointed, closely set teeth, re-
curved and placed in a broad group with an outer row of larger, conical, and pointed
teeth. The vomer is furnished with a small, arrow-headed patch of very minute
teeth, and the palate bones with a narrow band of similar teeth. The tongue is broad,
and armed with a patch of similar teeth or asperities.

The dorsal fin is long, but not much elevated; it has ten spines, the anterior short,
the sixth and seventh longest, and ten branched rays longer than the spines. The
pectoral is rather broad ; it begins just at the back of the opercle and terminates at
the root of the second anal spine, and has fourteen rays. ‘The ventral arises nearly
with the pectoral, and ends rather behind the vent; it has one stout spine and five
soft rays. The anal arises opposite the root of the ninth dorsal fin and terminates in
a rounded extremity with it behind; it has three spines, the anterior short, the others
long and stout, and ten branched rays. The caudal is large, broad, slightly notched
behind, and has seventeen rays.

The scales are large, quadrilateral, straight and broadest before, rounded and ciliated
behind. ‘The lateral line runs parallel with the dorsal arch to the extremity of the
dorsal fin, whence it descends to the median plane.

HOLBROOK, FISHES OF FLORIDA, GEORGIA, &e. BY

Description.—The head is large, broad, rather convex above, compressed at the
sides, with the snout very full and rounded. The eye is small; it is placed twice its
diameter from the snout, 52 diameters from the extremity of the opercle, with its
lower margins near the median plane of the head. The anterior nostril is tubular,
and very near the snout; the posterior is a fissure in the root of the nasal barbel.

The pre-opercle is large, strong, and semicircular. The opercle is long, narrow
with its angle somewhat prolonged. The opening of the mouth is very large trans-
versely ; the lower jaw and intermaxillary bone are each armed with a semicircular
patch of card-like, conical, and pointed teeth, arranged in several series; the tongue
is stout, thick, broad and covered with papillee near the tip and at the sides. The
superior pharyngeal bones are covered with numerous pointed, villiform teeth, and a
few teeth of rather larger size in front, with recurved points; the inferior pharyngeal
has an oblong patch of minute, card-lke, pointed, and nearly straight teeth. There
are eight barbels, all black and rather slender. ‘The maxillary is long, extending to
the middle of the pectoral fin, and is flattened at its root. The nasal is delicate; it
extends midway between the snout and the angle of the opercle; there are four
mental barbels equidistant from each other, but the two external are one fourth
longest.

The dorsal fin is elevated; it arises on a line with the posterior fourth of the
pectoral, and has one spine, which is serrated on its anterior margin, and six branched
rays; the soft dorsal is rather large, and is placed opposite the posterior half of the
‘anal fin. The pectoral is large; it arises rather in front of the termination of the
opercle, and ends with the root of the last dorsal soft ray; it has one spine, somewhat
flattened, and serrated at its anterior margin; there are seven soft rays. ‘The ven-
tral is short and placed far back, and extends to the root of the second anal ray; it
has eight branched rays. The anal is large, elevated and long, though it ends before
the root of the caudal; it has twenty-two rays. The caudal fin is large, broad, and
nearly square at its tip, and has eighteen rays.

SpLANCHNOLUGY.—Tie liver is very large, thick, and entire in front, but terminating in two lobes behind;
from each side of the anterior central portion projects a lobule, into the corresponding hypochondrium,
which are here represented by cavities lined with peritoneum, and as these cavities are contracted at
their orifice, they seem at first view to be exterior to the common cayity of the abdomen. The gall
bladder is large, subpyriform, and is concealed by the right Jobe of the liver. The stomach is broad
before, narrower, but thicker in its walls behind; it extends to about the middle of the abdominal
cavity, and is then reflected forward to form the pyloric portion ; it has numerous folds of mucous
membrane, and the pyloric valve is well marked. The small intestine is twice as long as the animal
itself, and has numerous convolutions. The rectum is broader than the small intestine, shorter, and

without a fold or valve. The kidneys are large and consist of two portions; one flat, ribbon-like, and

placed along the spine, the other large, triangular, with its base lunate, and partly beneath the air
bladder, though the greater portion is bebind it. There is no urinary bladder. ‘The air bladder is very
large, sub-cordiform, though it is rounded behind, and not very deeply notched before. Its outer wall
is thick, firm, shining, silvery; its cavity is not entire, but is partially divided.

Dimensions. The distance between the angle of the opercle and the tip of the tail
is equal to three heads and one eighth; the greatest elevation without the dorsal fin
is equal to three fourths of a head; total length nine inches. )

CHARACTERS.—Head small, but in some elongated, in others rounded or truncated;
mouth variable in size; teeth very minute; only one suborbital bone, the anterior ;
no pseudobranchie ; no air bladder ; scales proportionally large.

RemArKS.—This is a sub-family of Cottoids and includes only small or medium-
sized fishes, which are somewhat related to the Gobide. It embraces, as it now
stands, four genera, Etheostoma, Rafinesque; Pileoma and Boleosoma, De Kay; and
Peecilostoma, Agassiz.

BOLEOSOMA, De Kay.

CHARACTERS.—Head short, compressed, round in section of a circle; mouth small,
horizontal, slightly protractile ; opercular apparatus covered with scales ; opercle with
a small spine; branchial rays six.

RemArks.—Although De Kay placed this genus among the Percide, yet he was
aware that it did not properly belong to that family. As he says. it “contains no
genus combining the characters of two dorsal fins and six branchial rays ;’+ and he
further observes that Boleosoma approaches in the form of its head, etc., to Htheos-

Description.—The body is elongated, slender, compressed, and thicker below than
above. ‘The head is small, short, compressed, narrow between the eyes, with the
snout rounded and full, though not so broad as the occiput; it is smooth above, though
covered with scales on the sides. The eye is very large, and is placed half the
diameter of its orbit from the snout, and two diameters from the angle of the opercle,
with its inferior margin below the median plane of the head, and its superior at the
facial outline. The posterior nostril is very near the eye, at the end of the superciliary
ridge. The mouth is small, hardly reaching to the eye; the lower jaw is nearly as
long as the upper, though its teeth are received within it when the mouth is shut ;
both are armed, as well as the vomer and pharyngeal bones, with numerous, minute,
closely set, pointed, recurved teeth.

The preopercle is so rounded as to present no angle ; the opercle is small, triangular
with its base before and its apex behind, and is armed with a slender, delicate spine ;
the subopercle and interopercle are large.

The anterior dorsal fin begins in a line vertical with the anterior third of the pec-
toral, extends to the vent, and has ten spines; the posterior is more elevated, and has
eleven rays. The pectoral arises a little behind the opercle, and extends to the root
of the ninth dorsal spine ; it is slender, and has twelve rays. The ventral begins at
some distance behind the origin of the pectoral fin, but extends beyond it; it is
long, slender, has one delicate spine and five soft rays. ‘The anal begins slightly
behind the origin of the posterior dorsal fin, and terminates with it behind; it has ten
soft rays. The caudal is long, narrow, rounded behind, and has fourteen rays.

The lateral line runs along the superior fourth of the body to the end of the
anterior dorsal fin, whence it gradually descends to the median plane of the tail.

Dimensions. The length from the opercle to the tip of the tail is equal to four
heads; the greatest elevation without the dorsal fin, to three-fourths of a head; total
length three inches.

Arr. VI.—Researches on the Cryptogamic Flora of the State of Georgia.
By Pror. JuLien DeEsy.

Notice I.—On THE ORGANIZATION AND Morpronoay or CHLAMIDOCOCCUS PLUVIALIS.—Plate VII.

The study of cryptogamic botany has had but few votaries, and may yet be consi-
dered as in its infancy. During later years only has the microscope been applied to
the examination of these often minute but highly interesting productions, and although
some very able men have thrown considerable light on this difficult branch of natural
history, much remains yet to be done by future observers.

I have paid considerable attention to this subject while in Kurope and during my
travels in Central America, and have acquired a certain knowledge of the Fungi and
Algze which emboldens me to furnish to those interested in such subjects, a few notes
illustrative of such species as I have observed since my short residence in the United
States. Every fact stated I have seen myself, but being here in the “up country,”
without the necessary literary help, I may, perhaps, in some cases, be led to describe
as new, things already known to the public. I have to beg indulgence in behalf
of my isolated position. If any of my observations be thought interesting or in-
structive I shall be sufficiently rewarded for my labors. ‘

It may he well here to state that the microscope I make use of is a good instru-
ment, (of large size,) of Oberhauser’s, in Paris. It was made five years ago, has very
clear glasses, and three amplifying powers.

I shall, in this first notice, give a short account of a plant I have before met with
in Belgium,* and which I have lately discovered in this country also, namely, Chla-
midococecus pluvialis, one of the most interesting of fresh water algee, although one
of the minutest.

I have found Chlamidococcus in the counties of Cass and Rabun, in the hollows of
rocks exposed to the influence of all the atmospheric changes, and which were liable,
during rainy weather, to be filled with water and to dry up completely during seasons
of drought.

The Chlamidococcus pluvialis is synonymous with the Hzematococcus pluvialis of
Flotow, and Protococcus pluvialis of Kiitzing. This genus is very nearly allied to Chla-

the roof of my father’s house.

midomonas and to Gleococcus, and, if I mistake not, one of its forms is identical with
the Diselmis viridis, described by Dujardin in his Natural History of Infusoria, as an
animal. Kiitzing mentions this species in his work entitled “ Ueber die Verwandlung
der Infusorien in neideren Algenformen (Nordhausen, 1844),” and gives it as an
example of the impossibility that exists of separating distinctly the animal from the
vegetable kingdoms. Von Flotow (in Nova Acta Academ. Nature curiosus, Vol.
xx., p. 11, 1844,) has given a long account of it, but his work contains many errors
of observation and of induction. Alex. Braun (Betrachtungen tiber die Erscheinung
der Verjiingung in der Natur. Leipzig, 1851,) has, in divers portions of his book,
given, in a fragmentary form, by far the most elaborate treatise on Chlamidococcus
with which we are acquainted. His observations are most accurate and interesting.*

I have been happy enough to fill up some gaps in the history of this minute am-
phibolical plant, and shall give as complete an account of this species of Alga as it is
in my power.

Chlamidococcus is found, in dry weather, forming a dirty, brownish or reddish tena-
ceous crust, spread in the small hollows of rocks; itmay be scraped off with a knife.
If put into water it very soon softens, and we find it to be formed of a number of
simple round cells. These cells are all of one kind; their diameter varies from 1-10th
to 1-36th of a millimetre, their outer membrane is thick, their contents finely granular,
and of a reddish color, nearly opaque. Inside we find from two to six grains of
amylon (fecula) whose diameter does not exceed the 1-120th of a millimetre, as a max-
imum, and which were first recognised as such by Alex. Braun, who says that he has
discerned in their centre a speck (nucleolus) which turns reddish by the application
of the tincture of iodine, whereas the remainder of the amylon grain takes the charac-
teristic tint of fecula. This would indicate a proteine substance in a thick coating of
amylon.

In the middle of the cell, (but very difficult of observation, on account of its opa-
city) is found a large, delicate cytoblast. Fig. 1.

All the round cells above described are, by the ordinary tests, found to be formed,
like nearly all other cells, by two coatings : an exterior one of gelin} and an interior

[* I regret not having been able to consult Prof. Morren’s Physiological Researches on the Belgian Iydro-
phytes, namely, his fifth memoir on the History of the Genus Heaematococcus of Agardh, not having been able
to procure this work.

+ Several kinds of cellular membrane are usually confounded under the name of cellulose: I recognise as
these principle forms: Ist. The amyl cell membrane, which turns blue by the simple applicaticn of tincture of
iodine. 2nd, The gelin cell membrane, which only turns blue by the combined action of sulphuric acid and the
tincture of iodine. 3d. The bassorin cell membrane, which takes a brown or yellow coloring by the preceding
tests. 4th. ‘lhe protein cell membrane, which takes a rich orange tint by the tincture of iodine, but can he
distinguished from the bassorin cell membrane by its behaviour when treated with hot nitric acid. The three

one (Primordialschlauch) firmly adhering to the inner surface of the exterior one, and
which remains visible after the first has become entirely destroyed by a prolonged
immersion in sulphuric acid.

The outer membrane will often slip off during the experiment, as seen in fig. 2.
Besides the larger grains of amylon already mentioned a considerable number of very
minute ones are seen as small specks adhering to the coating of protoplasma, which
constitutes the primordialschlauch.

Following with care the successive changes in these reddish cells, we observe, first,
that the red color retires from the outer part of the cell, so as to concentrate, as it
were, around the central cytoblast, leaving a zone of a paler color around the peri-
phery, as seen in fig. 3. Soon after this a separation of the cell contents takes place,
and two new cells (secondary cells) are seen to have been formed in the interior of
the parent cell. These are fixed, round, and have a nucleus. Fig. 4. This takes
place during the first, second, or third night after the immersion. Very shortly after-
wards these two younger cells again divide into two others (tertiary cells), so that
one primitive cell now contains four smaller ones. Fig. 5.

The four newly formed tertiary cells are very different from the primary one which
produced them ; they do not exceed the quarter of the latter one in size; their shape
is oval; they are red, with a paler yellow ring, Fig 6. But the most interesting
fact is the existence, at the narrower extremity, of two hyaline, flagelliform appen-
dages, which, by their continual motions, give to the plant a rapid rotatory, slightly
undulating, progressive motion through the water, Fig. 7. These processes are
analogous or identical with what has been observed in Cidogonium, Vaucheria, Vol-
vox, Gleococcus, Chlamidococcus, Botryocystis, Gonium, Pandorina and other alge.
Their length exceeds the diameter of the cell that bears them; they are transparent,
very slender and only distinctly visible when their motion is stopped. The flagelli-
form appendages seem to be formed by an exsudation or prolongation of the primor-
dialschlauch, through the outer cell-membrane, being to all appearance wanting in the
young cells. The Chlamidococcus have generally a rotatory motion from right to
left, but they occasionally turn in the opposite direction, as I have distinctly noticed.

These ovate flagel-bearing tertiary cells are endowed with motion for a period which

does not exceed three days, and is dependent on the state of the atmosphere. They
gradually grow to four times the primitive size, and as they grow, the narrower ex-
tremity lengthens into a kind of beak, or rostrum, which bears the two flagels. This
rostrum is always transparent, empty, and is incapable of any kind of motion. Fig. 7.
The whole cell has a pyriform appearance. It has, from the first period of its
existence, secreted an external transparent delicate membrane, which widens and
expands every hour, Fig 8. This outer covering seems to be of a gelatinous or
semifluid amorphous nature (probably gelatinous gelin). As this outer membrane
developes itself it gradually encloses the flagelliform appendages, and proportionately
slackens their motions, so as at last to stop these altogether, Fig. 9. These cells are
the gonidia of some botanists, the macrogonidia of Braun.

By degrees the red matter in these gonidia concentrates around their central
nucleus, and the outer paler zone acquires a green color. In this green portion (gela- |
tinous chlorophyll) may be seen, 2, 3, 4, 5, or 6, larger amylon grains, besides smaller
specks of the same substance mixed with minute drops of oil, and still minuter par-
ticles of globulinar chlorophyll. Fig. 10.

These cells, if submitted to the ordinary tests, (iodine and sulphuric acid) show
that the outer wide membrane is composed of gelin, the quite interior one which is
closely applied to the inner surface of the latter being protoplasma (protein substance).
The internal green chloryphyll remain unaltered by the tests, but the red portion
seems to divide into a number of separate globules, which acquire a deeper and more
intense coloring, indicating the presence of protein substance, probably mixed with
some oily or waxy compound and some peculiar coloring substance. The coloring
matter is soluble in rectified oil of turpentine and in ether, and is, perhaps, a mixture
of Erythrophyll and Xanthophyll. These two substances have been proved by Mulder
and by Kiitzing to be formed by the disoxygenation of the chlorophyll under the
influence of strong light, of cold, and of other causes. The coloring matter of the
Chlamidococcus differs from all other red coloring matters in plants (known to me) by
its not being turned blue by the action of alkalies.

The chemical structure of the outer coverings of these adult gonidia show that
these cells of Chlamidococcus differ considerably from the swimming spores of many
other algee, which I believe to be (as asserted by Kiitzing, Grundziige der philosophi-
schen Botanik, p. 295) in nearly all cases, formed externally by an unprotected pro-
tein membrane, which it is easy to distinguish from the bassorin cell membrane of the
parenchym cells of many cryptogamia by boiling with nitric acid and adding ammonia.

Hach of the first gonidia (cells of the first swimming generation, or cells of tertiary
formation) finally becomes stationary, the outer gelin covering hindering all further
motions of its flagels. These now disappear, being seemingly re-absorbed into the
general coating of protoplasma. The wide outer covering remains unaltered. The

larger amylon grains which, until now, had been distinct, disappear. Fig. 11. Between
midnight and morning a longitudinal division of the cell takes place, which divides
it into two fixed, immovable cells (cells of quaternary formation.) Fig. 12,a. Very
shortly after this (one or two hours after) these last formed cells are each in their
turn seen to subdivide into two active gonidia furnished with flagelliform appendages.
Fig. 12, 6. These last (cells of quinary formation) move actively even before leaving
the envelop of the mother cell, but before dawn finally break through it. They then —
live the same independent lives that the first swimming gonidia had led, and go on
moving actively for two or three days.

This,second generation of flagel-bearing gonidia differs from the first only in being
green from the onset, each cell having at its birth and ever afterwards a small, red,
central mass; whereas, be it remembered, the first generation of active gonidia were
red at first, and only acquired a green color some time after their liberation from the
mother cell. Figs. 13, 14.

After a period of from 48 to 72 hours (and always during the hours of darkness,)
the second generation of motive gonidia each separate into two immovable cells, (6th
formation, Fig. 16,) each of which in their turn divide into two new motive gonidia,
(gonidia of third generation, 7th cell formation. Fig. 17.) This takes place in exactly
the same manner as in the preceding generation, and this multiplication goes on iden-
tically and uninterruptedly for a period of about six weeks, producing in that space
of time from twelve to nineteen successive generations of motive gonidia.

The latter formed generations often differ somewhat from the first in having the
central red spot nearly obsolete or altogether wanting; (fig. 18,) and in some cases as
first seen by Von Flotow, in containing large internal hollow spaces, which displace
the green lining of gelatinous chlorophyll, giving a lacunose appearance to the cell.
Fig. 19. These internal vacuoles sometimes displace the central red mass, and render
it parietal, so as to make it resemble an eye, and give to Chlamidococcus the appear-
ance of a Chlamidomonas. Fig. 20. The green gonidia are very sensible to light,
they collect in greater numbers in that part of the vase they are held in, which receives
the sun’s rays. Their respiration is identical with that of other green plants, i. e.,
they disengage oxygen during the day and carbonic acid during the night. This fact
was noticed by Ehrenberg with respect to Chlamidomonas, without his suspecting,
however, its vegetable nature, as he describes it as having eggs, an eye and a testicle,
which are nothing else than the grains of amylon, the red mass, and the cytoblast
we have spoken of above, and which exist as well in Chlamidomonas as in Chlamido-
coccus. Hach of the gonidia of the 19th or last of the motive generations, gives birth
to two immovable green cells, each of which shortly after is in its turn divided into
two other cells, but which, differently from what has been taking place in all the pre-
ceding generations, are unproductive of a new generation of cells.

64 DEBY’S RESEARCHES ON THE CRYPTOGAMIC FLORA

These last cells soon take a rounded form, become immovable, attain gradually their
full size, absorb their flagelliform appendages, lose their wide outer membrane, cover
themselves with a tenaceous and thick cell membrane, turn gradually to yellowish,
then to red, or to a brownish-red hue, and now all organic functions seem to lie dormant
in them for awhile. Fig. 21.

If these red cells be submitted to the action of iodine and sulphuric acid, they again
take a green color. I attribute this to the fact that the gelin coating is turned blue
and the protein coating yellow by these tests, the combination of which two colors
forms green, but this is only hypothetical.

In some accidental cases the last generations of gonidia, instead of following the
above mentioned order of phenomena, divide rapidly into 2, 4, 8, 16, 32 smaller gonidia,
which are at first aggregate inside the mother cell which has produced them. (Fig.
22.) They, however, ultimately break loose and swim about freely for some time,
without seeming either to grow larger or to produce new cells. These are the Micro-
gonidia of Alex. Braun; they vary from ;;; to 5; of a millimetre in diameter, have
two flagelliform appendages, are of a yellowish or yellowish-green color, and have the
rostrum slightly reddish. Fig. 23.

The larger fixed red cells formed by the last (19th) generation of gonidia remain
dormant for an indefinite period if left in water. They even seem to die and decompose
if left there for a great length of time. But if the water they are contained in be
slowly evaporated to dryness in the sun, be it only for a few hours, and fresh water be
poured over them, new life is soon manifested, and generally by the next morning
fresh gonidia (of primary generation) will be found fully developed and swimming
actively about. These will go through the whole series of vegetative phenomena we
have above described, and prepare a future generation of fixed cells, destined in their
turn to perpetuate indefinitely the existence of this species of plant.

If, instead of immersing the immovable, dormant red cells in water, we simply keep
them in a state of dampness for some hours, they will generally divide into two fixed
cells (of secondary formation), these in turn will divide into four (of tertiary formation
and corresponding with the first generation of appendiculated gonidia) fixed, globular,
unappendaged cells; then again into two (quaternary), then, last, into two (quinary)
others, and so on for a considerable period of time, which I have not followed out, but
which is, most hkely dependant upon temperature and the quantity of water furnished.
These cells rarely attain above half the size of the primitive mother cell, they are
generally globular, of a reddish-brown color, and always destitute of flagelliform ap-
pendages.

In the same way that the last swimming gonidia return to the form and nature of
the parent cell—so do the last generations of this abnormal form of Chlamidococcus
also produce larger cells of a thicker and darker color, which cannot be distinguished

OF THE STATE OF GEORGIA. 65

from the primitive mother cell, and which, after desiccation, are also capable of repro-
ducing all the above described series of phenomena; on which account they must be
considered as identical in functions and nature.

In the last named form of Chlamidococcus, in which none of the cells are motive,
the wide, outer membrane, which in the normal type envelopes each gonidia, is
also secreted, but the divers cells being very close to one another, the consequence is
that this gelatinous matter finally forms an apparently continuous amorphous crust
of a pale yellowish color, in which the successive generations of cells are immersed.
Chlamidococcus is now indistinguishable, by a cursory examination, from the genus
Pleurococcus, Fig. 24. Braun, who has noticed these two modes of growth, noticed
also that in the last described form, the production of 4, 8, 16, 32, &c., microgonidia
took place occasionally just as described in the more perfect form of Chlamidococcus,
but these microgonidia are globular and unappendaged, Fig. 29. I believe that in
both cases the production of microgonidia must be attributed to quite accidental
causes, such as a diseased state of the producing cell, a peculiar tenacity of its outer
membranes, or an over-excited formative power brought on by unknown causes. If
this were not the case these microgonidia would not die away without producing fur-
ther generations or acquiring the ultimate dimensions of macrogonidia, which they
are never known to do.

CONCLUSIONS.

The curious vegetation of Chlamidococcus above described may be understood in
two different ways :

1. We may imagine every cell, (be it primitive mother cell or motive gonidia) as a
spore, or complete individual plant, and admit that as in the lower classes of animals
we have here “ alternations of generations.” By changing the word animal into the
word plant, Steenstrup’s description of this singular fact would read as follows:

“ Alternation of generations, or the remarkable phenomenon of a plant producing
offspring, which at no time resembles its parent, but which, on the other hand, brings
forth a progeny, which returns in itsform and nature to the parent, so that the maternal
plant does not meet with its resemblance in its own brood, but in the descendants of the
second, third, fourth or(. . . nth) degree of generation; and this always takes
place in the different plants which exhibit the phenomenon, in a determinate genera-
tion, or with the intervention of a determinate number of generations, &c.” (See J.
J. Steenstrup, Altern. of Gener., translated by George Busk, 1845, Ray Society.)

Now, in Chlamidococcus, we may suppose we have a primitive plant (first red, fixed
cell) producing an offspring (motive gonidia) which at no time resembles the parent, but
brings forth a progeny which returns (after several generations) im its form and nature,
to the parent cell, so that the maternal Chlamidococcus does not meet its resemblance in

17

66 DEBY’S RESEARCHES ON THE CRYPTOGAMIC FLORA.

its own brood, but in its descendants of the 14th or 15th compound generation. We
might carry on this comparison much further, but as we believe it to be a simple
analogy with the facts stated by Steenstrup as existing in the Meduse, Polypes,
Corallines, &c., and no identity, we prefer not prolonging here what we consider to be
useless and sterile discussion, and we shall at once pass to the second manner of in-
vestigating the matter, which seems more consistent with philosophical induction as
applied to Algology.

2. All plants are produced by the multiplication of a simple cell, which in the
cryptogamia is called a spore. If we follow out the subsequent development of such a
spore, we observe it generally to produce a succession of vegetative cells (not spores),
until having at last attained maturity, (having produced a determined number of
such cells) it forms one or several peculiar cells of a different nature from the antece-
dent one. These last are the real spores destined to produce a new succession of
vegetative cells, and after these a second generation of spores. The cells formed ante-
riorly to the spores are generally connected together by cohesive or intercellular sub-
stance, so as to form a parenchymatous mass, or thallus. The formation and deposi-
tion of cells may take place according to three dimensions of space. It may take
place in length (in a linear direction), and we have a filamentous (articulated) thallus,
as in Conferva, Zygnema, &c. It may take place in length and in breadth simulta-
neously, and we have a foliaceous thallus, as in the Ulvace, &c.; or, lastly, it may
take place in length, breadth, and height (thickness) at the same time, and we obtain
a massive parenchymatous thallus, which may be regular or irregular.

In the development of Chlamidococcus in a damp place, or when kept humid, as
above described, we have an exemplification of an alga produced by an ordinary
spore, and consisting in an irregular foliaceous thallus, which, after growing for a
determined time (by production of new vegetative cells) dies away, all but the last
formed spores, which remain dormant until called into life by external circumstances.
May we not consider also the development of the Chlamidococcus, immersed in
water, as a growing plant, in which the ordinary vegetative cells are free (instead of
being united into a so-called compact thallus) andin which the terminal or last formed
cells, just as in other algze, end by giving birth to spores? I think analogy and mor-
phological considerations lead to the adoption of this manner of viewing the subject.
In fixed alge the cells are immovable, and united to one another in the thallus; in
the form under consideration they differ only in being free and being furnished with
prolongations of the inner cell membrane, which give them for a short period limited
locomotive powers. In the crustaceous form of Chlamidococcus, where these flagel-
liform organs would be useless, we find them to be wanting, and yet the plant is
fertile that is, bears at last well-formed spores at the surface of its thallus, so that we
may consider these curious appendages of very secondary importance in the organic

OF THE STATE OF GEORGIA. 67

economy of this plant. According to the above expressed views I would define

,Chlamidococcus as a plant formed by a successiwely deliquescent and evanescent thallus,
each vegetative cell of which is free, 1s endowed with an independent motion (produced by
two lengthened flagelliform appendages) and has an independent life. Kach new gene-
ration of four cells being accompanied by the destruction of the precedingly formed
part of the thallus which has produced it. The terminal (or last formed) cells of
this vague thallus produce globular, fixed, unappendaged red spores. These spores con-
tain from two to six large grains of amylon and acentral cytoblast. The fully
developed evanescent parenchym ? cells of the thallus? are green, with a red central -
(not parietal) mass, in the middle of which is situated the cell nucleus.

In an aberrant form this alga constitutes a continuous, non-evanescent thallus, in
which the cells are globular, unappendiculated, and united by an amorphous inter-
cellular substance. This discoid thallus produces at its periphery (surface), spores
identical with those generated by the typical form.

I believe the above definition to be consistent with the strictest laws of analogy, as
applied to the morphology of the lower plants ; if I have erred, I shall be sufficiently
rewarded for my labors if I should have attracted the attention of other naturalists,
and induced them to take up the study of this interesting branch of natural history.

Linnzus has said, “ Nullus character infallibilis est ;” but however little encouraging
this maxim may seem, it must not dishearten nature’s votary, who can only describe
things to the best of his abilities, in a way concordant with the present state of
science, and who must ever remember that perfection is the attribute of the Creator,
not of the creature, and that human science is only a very small, fragmentary, shape-
less particle of Omniscience, which last is beyond his reach.

By Joun Cassin.

1. SPERMESTES NiGRIcEPS. Cassin. Proc. Acad. Philada., VI., p. 185 (1852). Plate
VIIL, fig. 1, male; 2, female.

Form.—Small, bill large and strong, wing with the second primary slightly longest,
tail short, but wide, and with the feathers broad.

Dimensions.—Total length (of skin) about 32 inches, wing 1%, tail 12 inches.

Colors.—Male : head black, which color is extended to the breast aud sides of the
body ; on the last (the sides) the black feathers are tipped with white. Middle of
the abdomen and under coverts of the tail white. Back and wing coverts bright
reddish chesnut, primaries black with minute spots of white on their outer webs,
exposed portions of secondaries reddish chesnut, ramp black with minute white spots,
tail black. Bill and feet (in skin) light colored.

Female: entire plumage above brown, tinged with chesnut on the back, below pale
brownish white, with a tinge of yellow, and with a few traces of black on the throat,
primaries black edged with white, tail brownish black.

Hab.—Zanzibar.

Obs.—Of this handsome little species three specimens are in the museum of the
Academy, and belonged to the Rivoli collection. All of them are marked as from
Zanzibar. It is not in any considerable degree similar to any other species of this
genus with which I am acquainted, but is spotted with white on the wings like

70 CASSIN ON THE GENUS SPERMESTES.

Obs.—Though several specimens of this bird in the museum of the Academy have
been labelled in Europe “ F. nigerrima,” and “ F. aterrima”’, I have not succeeded in
finding it described. It does not intimately resemble any other within my know-
ledge, and may be easily recognized by its plain and uniform plumage. All the
specimens are labelled as natives of Borneo.

ART. VIII.—WNotice of Fossils from the Carboniferous Series of the Western States,
belonging to the genera SPiRIrER, BELLEROPHON, PLEUROTOMARIA, MACROCHEILUS,
Narica, and Loxonema, with descriptions of eight new characteristic species. By
Josepu G. Norwoop and Henry Prarren, of the Illinois Geological Survey.

SPIRIFER,

S. sprnosus, nob.—Plate IX. fig. 1, a, 6, 6 d.

Shell rather small. Both valves very convex. The dorsal valve bears five or six
rounded ribs on each side of the sinus. The ventral valve has four, and sometimes
five, similar ribs on each side the central lobe. The lobe itself vesembles a large rib,
being only-about double the size of those next to it on each side. The other ribs
eradually diminish in size as they approach the cardinal border. They are covered
with large and deep but irregular striz: of growth, which are most numerous near the
margin. Besides these large imbricated striae some of the most perfect specimens are
beautifully marked with finer concentric striz, visible only by the aid of a lens.
The surface of the shell is irregularly covered with short, hollow spines, projecting at
nearly right angles from their bases. On all the specimens yet met with the spines
are broken, the longest fragments measuring about one-sixteenth of an inch. In
addition to these spines, the whole shell, including the cardinal area, is covered with
minute granules. Where these are rubbed off there is the appearance of small open-
ings into the shell, giving it the aspect, somewhat, of being covered with a minute
coral. Cardinal area, triangular; high ; a little shorter than the greatest breadth of
the shell, and having sharp edges on the ventral valve only. The median slit is large
and open, and occupies about one third of the space left free from the encroachment
of the ribs of the dorsal valve.

Dimensions.—Length, six tenths of an inch ; breadth, eight tenths.

Comparisons and Differences.—This shell has nearly the form of the S. octoplicatus,
of Sowerby, but differs in having fewer ribs; in the sinus of the dorsal valve being
wide and rounded at its bottom; and also in all its ribs being rounded. When the
epidermis is well preserved, the spines with which it is covered will readily distinguish
it from all other species. .

Geological Position and Localities.—This species occurs near the top of the mountain
limestone, associated with Pentremites sulcatus, pyriformis, and florealis, Prodwctus

S. Lerpy1, nob.—Plate IX. fig. 2, a, 6, ¢.

Shell of medium size; extremely variable in form, some specimens being globose,
while others are rather flattened. In young specimens the cardinal border is equal
to the greatest breadth of the shell; in old ones the greatest breadth is towards the
middle. The dorsal valve is furnished with a sinus, having sharp borders. It reaches
to the beak, and opens under an angle of 16°. ‘There is one tolerably large rib at the
bottom of the sinus, and on each side of it we find another, which is rather flattened,
and placed like a step about midway from the middle rib to the top of rib bordering
the sinus. On either side of this the ribs number from six to eight. Sometimes there
are six or eight on one side and seven on the other. The varix of the ventral valve
is strongly projected above the rest of the shell, although its height is diminished by
a furrow which corresponds to the rib found at the bottom of the sinus of the other
valve. On the sides of the varix there are step-like projections, similar to those found
on the sides of the sinus. On a few specimens, however, these ribs are wanting on
one side, but are never altogether absent. On each side of the varix there are from
six to eight rounded ribs, similar to those on the dorsal valve. The ribs on both
valves project strongly. Some of the specimens are beautifully marked, especially
toward the front margin of the shell, by imbricating lines of increment. These are
disposed in such a manner as to show that the shell increased faster in length than it
did in breadth. Other individuals are entirely destitute of these markings. On all
well preserved specimens the surface is covered with fine strize, only to be discovered
un‘ler the lens.

Some of these striz are parallel to the ribs, and others to the free borders of
the shell, so that they cross each other, forming a kind of net-work. Those
radiating from the beak are rather more prominent than the others. The cardinal
area is of moderate height and triangular, the angle being 152°. It is covered with
perpendicular and transverse strize. Deltoid aperture open, and of medium size.

Dimensions.—Length, eight tenths of an inch; breadth, one inch.

Comparisons and Differences——This species comes nearest to the 8. acuticostatus of
De Koninck, but differs in its ribs, which are rounded, while those of the acuticostatus
are sharp. The supplementary ribs on the sinus and varix will, however, at once
distinguish it from that species. It is also a larger shell.

Geological Position and Localities.—This fossil is common at Chester, Illinois, in the
upper part of the Mountain Limestone, where it is associated with the S. spinosus.
Although frequently met with at that locality, well preserved specimens are very
rare.

S. Forsesit, nob.—Plate IX. fig. 3, a, 6, ¢.

Shell of medium size; its greatest breadth being along the cardinal line. Dorsal
valve rather more gibbous than the ventral, and furnished with a very shallow sinus,
hardly amounting to a depression, but which is well defined by a large rib on each
side. The sinus is formed of five ribs, the central one being large, with a smaller
one on each side, which last spring, a short distance below the beak, from the large
ones, which limit the sinus. On either side of the sinus there are from sixteen to
twenty-two simple ribs, marked by undulating lines of growth. On the ventral valve
the varix is not raised, but is limited by two furrows, wider and deeper than any
others on the valve, except the central one of the varix, which corresponds to the
large rib in the centre of the sinus of the opposite valve. The varix is formed by
two ribs, which originate at the beak and bifurcate after proceeding a short distance,
so that it is made up of two pairs of ribs, divided by the large central furrow. The
remainder of the ribs on this valve are like those on the opposite one. Cardinal area
unknown.

Dimensions.—Length, nine tenths of an inch; breadth, two inches.

Comparisons and Dijerences.—This species differs from the S. attenuatus of Sowerby,
which it most nearly resembles, in having fewer ribs on the sinus, and a much less
number on the whole extent of the shell; and also in the ribs being simple, while in
the attenuatus they are dichotomous. It cannot be confounded with any other species
known to us.

Geological Position and Locality.—It occurs in the middle of the Mountain Lime-
stone series, at Burlington, Iowa. We have not been able, so far, to obtain specimens
from any other locality, nor have we found the two valves united. It is rare.

BELLEROPHON.

B. percArtnatus, Conrad. Plate IX. fig. 4, a, 4, ¢.

This very beautiful shell, which was figured and described by Mr. Conrad in 1842,
in the Journal of the Academy of Natural Sciences, old series, is figured here on
account of its position in the coal measures of the west, as well as the greater size to
which it attains in western localities.

Geological Position and Localities—Found at Graysville, Illinois, and in Posey
county, Indiana, five miles below New Harmony, in clay shales belonging to the coal
measures.

Illinois State Collection.

B. MontrortrAnus, nob.—Plate IX. fig. 4, a, 8, c.

This species belongs to the same section as the B. Urii of Fleming, being sulcated
and not umbilicated. It is rather small, with the exception of the last whorl, the
mouth part of which is enormously expanded, both in length and breadth. The
shell is crossed from side to side by a series of large, wavy ridges, which are cut
through in their centre by a deep longitudinal furrow. The ridges and furrow become
obsolete on the expansion of the mouth. The entire surface is covered with fine
longitudinal ribs, so numerous that it is almost impossible to number them. The
mouth is, apparently, without a notch; exterior lip semicircular ; inner lip very much
thickened, and, with the central parts, projects so far forwards as to form with the
sides of the shell two semicircles.

Geological Position and Localities—This is another most beautiful species belonging
to the coal measures, and is found associated with the B. percarinatus and B. Uri at
Galatia, Illinois, and five miles from New Harmony, Indiana. |

On account of the extreme thinness and great expansion of the mouth, no entire
specimen has been met with. The dotted outline has been given from an internal
mould of the mouth which we were so fortunate as to obtain.

PLEUROTOMARIA.

P. GRAYVILLENSIS, nob.—PI. IX. fig. 7, a, b.

Shell small, being about half an inch in breadth and the same in length. Whorls
five, flattened above; the body whorl rounded ,below. Spiral angle 102°. Shell
covered with longitudinal lines, crossed by lines of growth, giving it the appearance
of being garnished with small tubercles. The upper line of tubercles on each whorl,
near the suture, is much more prominent than the others, forming a raised ornamental
band. The band of the sinus is large, and separated from the inferior part by a fur-
row. Mouth sub-quadrangular; exterior lip sharp; columella lip thickened, the
columella terminating below in a point.

Geological Position and Localities.—This species occurs in the coal measures, and is
quite common in the shales near the mouth of Rush creek, Posey county, Indiana,
and Grayville, Illinois. It is also found near Shawneetown, and in the neighborhood
of Galatia, Saline county, Illinois.

P. CARBONARIA, 70b.—PI. IX. fig. 8.

Shell of medium size. Length, 1 inch; breadth, 1 1-20th inch. Whorls five,
rounded, covered with strongly raised, sharp, longitudinal ribs, the grooves or furrows
between which are rounded, and much broader than the ribs themselves. The sinus
consists merely of a broader groove, in which there are two or three raised ribs similar
to those on the remainder of the shell, but much smaller. On the inferior half of
each whorl, below the sinus, both the ribs and furrows are much smaller than those

on the upper portion. Mouth nearly semicircular; lip sharp.

Fusus(?) inHaBitis, Morton.“ American Journal of Science and Art,” Ist Series,
Vol. xxix., p. 150, fig. 14, plate 3.

This species, which was found in 1834, by Dr. S. P. Hitpreru, of Marietta, Ohio,
occupying the same position it does further west, was referred by Dr. 8S. G. Morton to
the genus “ Fusus?” and published without any adequate description. Its occurrence
in the same geological horizon over so large a district of country, gives it an impor-
tance which renders it desirable to supply the deficiency.

Shell nearly globular; spire short, forming an angle of 105°. Whorls five; the
body whorl very large and inflated, while the remainder are comparatively small, and
occupy only one seventh of the total length of the shell. Aperture semi-elliptical ;
much longer than wide. Columella rather long, and furnished with a distinct fold.
The length of a large specimen is 1 8-10th inches. This species resembles somewhat
the M. Michotianus of De Koninck, but differs from it in its greater size, and in having
but five whorls; that species having six.

Geological Position and Locality.—This species is found in the middle of the coal
measures at Grayville and Galatia, Illinois, and rather more abundantly, but of
smaller size, in the shales of the same formation in Posey county, Indiana. It also
occurs, according to Dr. Hitpret# in the same part of the coal series of Ohio.

shell. The upper portion of each whorl is ornamented by a series of lines radiating
from the axis of the shell, which proceed outwards from the suture and then slightly

circular. Length, seven tenths of an inch; breadth, nearly the same.

Geological Position and Locality.—This species was found by Major T. C. Downey,
in the coal measures, one mile south of New.Harmony, Indiana, the only locality in
which it has yet been discovered.

only swelling out at the upper part, producing a deep suture between them ; they are
covered with slightly raised transverse ridges. Mouth long and narrow, three times
as long as broad, and terminating below in a shallow groove or notch, not prominently
marked except in well-preserved specimens.

Geological Position and Localities—This species has only been found in the coal
measures. It is very abundant on the Wabash, five miles below New Harmony,
Indiana, in the clay shales of that formation. It also occurs at Galatia, Saline county,
Illinois, in equivalent beds.

ART. 1X.—Plante Pratteniane Californice: An enumeration of a collection of Cali-
fornia Plants, made in the vicinity of Nevada, by Henry Pratten, Esq., of New Har-
mony ; with eritical notices and descriptions of such of them as are new, or yet unpub-
lished in America.

By Exias Duranp.

This collection, which was placed in my hands by the Philadelphia Academy of
Natural Sciences in the latter part of last year, is composed of about two hundred
specimens, many of which, unfortunately, are in a very incomplete state. It was
made during the spring and summer of 1851, in the vicinity of Nevada, a place
situated on Deer Creek, one of the affluents of the Sacramento river, and occupying
an intermediate position between the mountains of the Sacramento and those of
Calaveras county. Nevada stands at an elevation of about three thousand feet above
the level of the Pacific Ocean, near the junction of the granitic and schistose rocks.
To the soil of the former, as well as to that of the porphyritic lavas, are confined the
large pines, firs and arbor-vitee, while the nut pines and acacias thrive only on the
schistose rocks. I am informed by Mr. Pratten that many of his plants belong, ex-
clusively, either to the granitic or to the schistose formations, whilst others grow indif-
ferently on both.

Before entering upon a serious investigation of these specimens, I put aside all
those that were new to me, with the view of submitting them to my friends, Profs.
Torrey and Gray, who have had under examination several large collections of Cali-
fornia plants. To the great experience and friendly assistance of these léarned
botanists Iam highly indebted. They have been good enough to point out the species
which they had already described in manuscript, and to procure for me Bentham’s
Plante Hartwegiane, or descriptions of new plants collected by Hartweg in the moun-
tains of the Sacramento river—a publication extremely rare in this country, and in
which I found descriptions of many of the plants I had before me.

All the new species of Mr. Pratten’s collection, described either by Profs. Torrey,
Gray, Mr. Bentham, or by myself, amounting together to about forty, have been
united in this essay, and may be considered as new matter, not having been published
as yet in any American work. Whenever I have failed to obtain Professors Torrey
and Gray’s notes, (their manuscript being in the hands of the printer,) I have
endeavored to supply this want by giving my own diagnosis.

Smaller than C. pratensis, but same habit and inflorescence. Radical leaves long-
petiolate, sometimes entire, limb 12.15” broad, truncate at base, margin obscurely
sinuate ; but oftener, above the middle of the petiole, with 2, or more seldom, 3—4

sider as a form of C. paucisecta, although somewhat differing from Hartweg and Pratten’s plant. ‘ As is

frequently the case with California specimens, the radical leaves are wanting ; but towards the middle of the
stem the first cauline leaves begin to appear. These are 5=-7 pinnately divided, and answering pretty well to

colored flowers. In my opinion Z. asperum, D.C., Arkansanwm and elatum, Nutt., might
be considered as different forms of one species. £. asperum is somewhat canescent, but
they are all more or less scabrous, with appressed medio-fixed hairs; the lower leaves
are runcinate-dentate, those of the stem dentate or entire; the flowers are large,
varying from light yellow to orange, the petals have very long claws and obovate
limbs ; style short and thick, with a bilobed stigma. . elatwm (Nuttall’s specimen)
is a lank and elongated form about 3 feet high. Hilly sides of Deer Creek. August.

POLYGALACE A.

POLYGALA cucutiatra, Benth., Pl. Hartw. p. 299. “ Diffusa, puberula, foliis
ovalibus vel oblongo-ellipticis, obtusis retusisve ; racemis brevibus plurifloris, sepalo
infimo basi gibbo, alis oblongis, carina imberbi apice in cucullum oblongum producta.

Stems branching, prostrate, the lowest part perennial and almost woody ; branches
herbaceous, slender, 4—6” high, pubescent; leaves with very short petioles, the
lowest small ovate, the upper 6—8” long, rounded at tip or often emarginate, cuneate
at base, with margins slightly recurved, green on both sides and not punctate, pube-
rulent above, almost glabrous underneath. Flower (rose colored?) 4” long. The
exterior sepal concave at base, saccate, oblong ; the two superior a little smaller and
one-half narrower. They are all membranaceous and colored, the two lateral
(wings) twice longer and more slender, obliquely subovate-oblong, equalling the
wings of the corolla, and a little shorter than the keel. Lateral petals, or wings,
lanceolate and slightly adhering to the base of the keel. Keel split in front, dilated
above the base and contracted towards the middle, then abruptly dilated, subrhom-
boid and terminating in an erect obovate-oblong and obtuse hood. The stamens do
not reach the base of the hood ; the filaments are fixed to the keel as far as the rent,
where they become free. The style is flexuose, tubular, dilated at top and truncate,
the stigma resting on the margin. Ovary stipitate, capsule subsessile, orbicular,
emarginate. There are also, at the base of the leafy branches, short fructiferous
branchlets, bearing capsules rather smaller than those of the upper branches, and
perhaps produced by apetalous flowers.”

The few small specimens I find in Mr. Pratten’s collection differ only from the
above description in having the hood conspicuously mucronate; but Dr. Torrey
informs me that, in the specimens of Col. Fremont, some have the mucro, whilst
others have it not.

Bentham’s description of the radical leaves of C. yaucisecta, The upper leaves are ternate, and the leaflets of all
the leaves are rhombic-ovate, petiolulate and repand-dentate; each axil is furnished with a few-flowered stipitate
raceme, provided with a leaf-like 3-parted or dentate bract. The terminal raceme is 12—15 flowered; the sepals

are ovate, with a whitish margin, 4 the length of the petals, which are white slightly tinged with pink. The root
appears to be tuberous, and the stem and petioles are succulent.

82 PLANTA PRATTENIANA CALIFORNICA.

VIOLACE A.

VIOLA Becxwiruu, Torr.’s MSS. for Beckwith’s report, “subcaulescens, ad-
scendens, caule abbreviato; foliis caulinaribus biternatis vel palmati-sectis, decur-
rentibus, lobis vel segmentis oblonge-linearibus, hirsutis, pubescentibus; stipulis
minutis, scariosis, integris; sepalis linearibus obtusis, ciliolatis, petalo infimo ad basim
remisse saccato, purpureo, ad unguiculum luteo, 2 superioribus brevioribus dense
violaceis.”

Pratten’s plant, although evidently the same as V. Beckwithii, differs slightly from
the above description. It has but a few pentagonal reniform leaves on long margined
petioles; these leaves are 3-divided, or pedately parted with cuneiform 2—3 cleft
elliptico-linear segments ; stipules small, membranaceous, fimbriate ; two very minute
bracts about the middle of the peduncle; flowers rather small, on peduncles shorter

“Rhizoma short, ascending. Stems half a foot high. Inferior stipules two lines

more wide than long, on long petioles, with lobes ovate or oblong, obtuse or acute, and
mostly divided above the middle of the lamina; the upper leaves are generally trifid,
with the middle lobe larger than the others, on peduncles about two inches long, pro-
vided, above the middle, with two small approximate or distant bracteoles. Flowers
yellow? petals beardless. The appendices of the anthers very unequal; the superior
a little shorter than the anther itself, the inferior very short. Style clavate, incurved,
with an oblique stigma, and ciliate with retrorse hairs under the stigmatose part.”

In my specimens the stems are striate, branching, eight inches long. The leaves
are strongly veined, the inferior glabrous, cordate, palmately divided from about the
middle, with lanceolate lobes; the upper are pubescent-scabrous, ovate-rhomboid,
with lateral dentiform lobes. The stipules are foliaceous, broadly-oblong, mucronate-
dentate, or entire and lobed, attaining towards the middle of the stem twice the
length of the petioles. The flowers are numerous, on rather short peduncles, each
having two small bracts, distant or approximate, above the middle. Petals apparently

what bearded at the claw; spur wide and saccate; style incurved, ciliate with retrorse
hairs under the oblique stigma. Capsule ovate. Shady woods. May.

S. CALIFORNICA, spec. nov.? Caulis subramosus, debilis, pubescens, foliis caulinaribus
oblongo-lanceolatis, integris, ciliatis, fere semiamplexicaulibus ; cymis trifloris; calyce
ample elliptice-cylindrico, obscure striato, pubescente, dentibus late ovatis, margine

This plant, of which I have several other specimens collected at Calaveras by Dr.
Heermann, may be the 8. Virginica of Benth. Pl. Hartw.; but its characters are so
constant that I feel justified in separating it from that species, which it resembles at
first sight. It is more pubescent, the stem and calyx less striate than in the latter,
and I have not seen more than three flowers in each cyme, whilst S. Virginica has
generally more, and SS. rotundifolia, with which it has likewise some affinity, has
them solitary or in twos. Its habits are also very different from those of S. regia and
S. Greggti, which are robust and erect plants, with thickish oval or obovate leaves. In
S. regia the petals are entire, in 8. Greggit they are 4-fid with linear lobes, in

22

84 PLANTA PRATTENIANA CALIFORNICA.

S. Californica the middle lobes are considerably larger than the lateral. Internodes
2—4 inches long. The calyx is not clavate, but uniformly expanded and perfectly
. cylindrical, with delicate strize. The lamine of the petals are always four-lobed, two
large obtuse lobes in the centre and two smaller and acute on the sides. Flowers
deep scarlet. Hills of Deer Creek. May.

S. CALIFORNICA, var. miniata, var. nov. Caulis erectus, simplex, 6—8 pollicaris,
foliis ovato-lanceolatis acutis, basi attenuatis, sessilibus; internodiis 1—13 pollicaribus;
cymis 3-floris; calyce omnino conformi S. Californice ; petalis miniatis, bilobatis
cum dentibus lateralibus duobus.

The most striking characters of 8. Californica are the tubular form of the calyx
and the four-lobed petals; in the variety miniata the petals are not exactly four-lobed,
the lateral teeth are too small to be accounted lobes, but the calyx and the claws of
the petals are exactly the same. The latter might, however, prove to be a new
species, if the minium color of its flowers is constant. Its leaves differ in being oval-
lanceolate and more attenuate at base than S. Californica; it is also a smaller plant,
with comparatively short internodes. Dr. Heermann brought it from Calaveras,
mixed with specimens of S. Californica.

Banks of Deer Creek. August. I have under my eyes three very distinct forms
of Zauschneria; one, (var. «.) pubescent, narrow-leaved, with bright red calyces and
corollas. The second, (var. s.) Mr. Pratten’s plant, is villous-canescent, with broad-oval
leaves; calyces of a fulvous color, longitudinally veined, and tips of petals brightly red.
The third form, which might prove a distinct species, is also villous-canescent,
with ovate-lanceolate acute leaves, repandly denticulate, and very much like the
floral leaves of Cinothera biennis ; calyx and corolla of a uniform bright scarlet
color; flowers large, bracteate, on a long terminal spike. The latter was collected

by Dr. Heermann at Posa Creek, South California.

fruit, also in the minute stylopodium; leaves also different, the general involucre
wanting or about one-leaved. (Dr. Torr. in litt.)” The whole plant is but slightly
pubescent and not hairy as is O. brevistylis; the configuration of the leaflets is some-
what trapezoid, shorter than in the other species, and petiolulate, with a few rounded
lobes or teeth. The fruit is rather truncate below the stylopodium, the styles very
short and parallel as far as the uncinate top. Near the banks of Deer Creek. July.

This remarkable species belongs to the section of Cornus with yellow umbellate
flowers, which includes the Cornus mas of Europe and our Cornus florida. So far,
specimens collected by Dr. Bigelow and in Whipple’s expedition, had proved insuff-
cient for the complete description of this new species, on account of their being too
far advanced in florescence ; but two small specimens, just in bloom, collected by Mr.
Pratten on the banks of Deer Creek, have permitted Dr. Torrey to finish his descrip-
tion. The latter specimens, which were only the tip of flowering branches, might
have been taken, at first sight, for Dirca palustris.

PLANTH PRATTENIAN® CALIFORNICA. 95

Mr. Pratten’s plant, as well as other specimens collected at Calaveras by Dr. Heer-
mann, are all in the first stage of florescence and dwarfish ; the scape is 5—8-flowered,
3—5" high; the leaves are round-spathulate,‘1—12" long including the petiole; they
are entire, with a conspicuous subscarious margin; the filaments are completely
connate in a tube of a deep violet color, shorter than that of the yellow anthers and
contiguous with it; the anthers, therefore, appear quite sessile, and are broader than
in D. meadia and its varieties, and rather obtuse. Specimens collected by Mr.
Nuttall, on the plains of the Columbia river, labelled by him D. ellipticum, and, I
believe, as yet unpublished, are perfectly identical with Pratten and Heermann’s
plants, although in a more advanced stage of florescence and greater development
of scapes and leaves; the latter, however, do not exceed 22" in length including
the petiole. I suspect that Beechey’s California specimens, from which Decandolle
has, in part, evidently, described his D. integrifolium, belong also to the same

species.

+So far, four or five species of Dodecatheons have been described ; but there is such a discrepancy in their
descriptions, and their forms are so variable, that I felt inclined to follow my highly esteemed friend Prof. Asa
Grey, in uniting them all together into a single species. However, on examining attentively and comparing the
numerous specimens I have before me, I can not but find at least two very distinct species and several varieties,
which I divide as follows :

* Filamentis liberis in tubum approximatis.

DODECATHEON meanra, Linn. o. Foliis ovato-oblongis, integris vel repando-dentatis ; umbellis multifloris ;
floribus nutantibus; involucri foliolis ovato-spathulatis lanceolatisve ; filamentis flavis glandula purpurea ad
apicem instructis; antheris elongatis acuminatis. In regionibus orientalibus usque ad flumen Missouri.

3. Var. pauciflora.—D. integrifolium, Mich. non D. C. Foliis oblongo-ovalibus integerrimis (nonnunquam
repando-dentatis) ; umbellis paucifloris, 3—5; floribus suberectis, dense purpureis; antheris atro-violaceis ;
bracteolis linearibus. Ad orientem et occidentem fluminis Missouri usque ad Montes Scopulosos.

y. Var. integrifolia,—D. integrifolium, Nutt. non Mich. neque D.C. D. frigidum? Cham. Foliis numerosis,
congestis, oblongo-ovatis, et una cum petiolis vix 3-pollicaribus. Scapo 5—10-floro, 6—10” alto; involucri foliolis
lineari-lanceolatis acutis, nonnunquam longissimis; floribus breve pedicellatis, suberectis, albis, vel purpureis-
Vidi specimen e regione arctica, D. frigidum inscriptaum, omnino consimile. Habitus a pracedentibus dis-
similis atque minor; forte species distincta? In regionibus Oceani Pacifici.

** Filamentis in tubum connatis.

D. exirpticum, Nutt. Partim D. integrifolium, D. C.; partim D. frigidum, Cham. in D. C. Prodr. In California
et Oregon. Nuttall, Beechey, Heermann, Pratten.

I have examined, in Mr. Kilvington’s garden, an abundance of seedlings of Dodecatheon in flower, obtained
from different sources ; but all from the species D. meadia, var. o and 8. In the former the flowers are hanging, and
vary in color from white to lilac and different shades of purple ; the anthers and filaments are yellow, the glands
deep purple. The leaves are from 4—8" long. In the latter the flowers are generally erect, of a deep purple
color, with violet anthers and yellow filaments ; the leaves are oval, oblong, entire, but sometimes coarsely den-
tate and not marginate. In both the anthers are very acuminate, and the filaments free, remote, or somewhat
approximated, but never connate as in D. ellipticum. I have not seen D. dentatwm of Hooker, but I suspect it
to be the var. g, with dentate leayes, as I have seen some, remarkably so, in Mr. Kilvington’s garden. Some
seeds were ol)tained from the far west, and I have no doubt that var. 8, came from that region; the rest were
from Harper’s Ferry, Virginia, and the Southern States.

I see very little cause for separating this from F. albicaulis. It seems to differ only
in being perfectly glabrous.

More rigid than the eastern species, with smaller and narrower leaves, somewhat
fasciculate in the axils; segments of the calyx shorter; limb of the corolla rather
larger and more deeply bilobed.

I have very little doubt that Mr. Pratten’s plant is the above described, although
the branches are perfectly smooth and the leaves so rigid as to be almost spinescent.
There are no good flowers to judge from.

Orthocarpus lacerus has a great affinity with O. lithospermoides ; but the leaves
are more incised, the spikes less dense, the bracts almost palmately 5—7-partite, not
turning yellow by drying, and pubescence more green. In the latter the corolla is
yellow, and rose colored in the other. It is easily distinguished from O. hispidus by
its much larger corolla and conspicuously saccate lip.

The whole plant canescent-tomentose; stem quadrangular, rigid, 15—18, high;
leaves sessile, cordate, oval-lanceolate, entire or with a few small teeth, veined and
sprinkled over with small pellucid glands. Capitula axillary and terminal, very
crowded; exterior bracts foliaceous; interior setaceous and very villous. Flowers pale
yellow, with a few small purple dots. Calyx tubular, striate, tomentose, as long as
the tube of the corolla. Stamens exserted, with purple anthers. A very aromatic

This species is easily distinguished from the others by its more exserted corollas,
villous tubes, and very long linear lobes protruding about half an inch above the
teeth of the calyx.

ART. X.—felation of Atomic Heat to Crystalline Form.
By J. Airxen Meas, M. D.

Very probably in the atomic constitution of matter we are to seek the true material
basis of the whole Science of Nature. The unity of Natural Science—as displayed
in the mutual relations and connections of its different parts—here finds a positive
expression. Therefore, Natural Science, as a unit, becomes philosophically intelligible
in proportion to the clearness and accuracy of our views concerning the aggregation
of passive atoms or ultimate particles into Forms,—whether organic or inorganic,
whether specifically or generically impressed. But the comprehensive study of such
ageregations, requires the contemporary investigation of the physical agent which
brings together inert atoms and retains them in contact,—which preserves as well as
produces the form.

Under the influence of the attractive principle, matter everywhere tends deter-
minedly to assume a definite shape. Hence crystallization is perceived to be as
common a characteristic of the inorganic, as vitality is of the organic world. Yet if
we may judge from the standard works of the day, upon these subjects, the cause of
the one is involved in as much obscurity as that of the other.

A crystal is inanimate matter individualized, or endowed with a form, in virtue of
which it approximates the unorganized to the organized kingdom. The difference
between the most complex crystal and the simplest plant is of course extreme; but
while on the one hand physiologists have carefully detailed these differences; on
the other, they seem to have lost sight of the striking analogies which exist between
the seriate results produced alike in the crystalline and the animal and vegetable
worlds, by a methodical intermittency of action, on the part of their respective
developing agents. Thus the concentric layers of wood in the trunk of a tree, between
which lines of demarcation are more or less evident,—as is especially the case between
the duramen and alburnum of the lignum vite and the coco-wood,—indicate the
successive periods of activity and repose of the formative principle. So the lines of
cleavage in a crystal silently assure us that the attractive power is intermittent in
action, and that along these weak planes it had ceased its exertions for a while, or,
at least, had acted very feebly.* Among the numerous and beautiful forms assumed

106 MEIGS ON THE RELATION OF

by snow-crystals, we find specimens from whose primitive rays are given off lateral
spines or branchlets in pairs, directly opposite to, and separated the same distance
from each other. One basal ray with its secondary spines is the fac-simile of all the
rest. Now this tendency to the repetition of precisely similar parts is seen not in the
formation of a crystal only, but also in the development of the highest plants, in
zoophytes and in the lower mollusca and articulata where it embraces entire groups
of organs. Thus in the highest forms of the Echinodermata, five precisely similar
rays are developed around a common centre. ‘The same tendency is seen in the eight
or ten tentaculee which surround the mouths of the dibranchiate Cephalopoda. Similar
examples are presented by the Annelida. In all these instances it is evident that the
developing force has acted methodically from a common centre, towards the accom-
plishment of a definite end or object—the production of a special form. In elassifi-
cation, form is of the highest value to the practical naturalist. But form is not
fundamental, it is merely secondary; it is the effect of the action of the developing
cause upon ponderable matter. Aided by a severe and cautious logic, the careful and
elaborate study of comparative morphology, it is reasonable to hope, will enable us
to advance from the known to the unknown, from the multitudinous forms of natural
objects to their physical cause. Moreover, it will probably lead to the discovery of
profound analogies between the organic and the inorganic worlds,—analogies mani-
fested through similarity in the modes of action of the formative or developing prin-
ciple. .

Crystallization naturally constitutes the first chapter in the history of comparative
morphology. A knowledge of crystallization is of prime importance to the chemist
and mineralogist in assisting them to arrange bodies in their natural groups; to the
natural philosopher in elucidating the laws of cohesive attraction; to the physiologist,
since it promises to throw considerable light upon the function of a fundamental
physical agent, the analogy of whose method of action with that of the developing
principle in the organic world, will lead, if not to their identification, at least to more
definite knowledge of the phenomena of growth; to the physician, as it affords some
clue to the pathology of symmetrical diseases; and lastly to the philosophic naturalist,
from its relation to organic morphology, through which, perhaps, will be attained
that much desired result, the demonstrative proof of a great general or archetypal
plan of organization.

A diligent and attentive inquiry into the rationale of the phenomena of isomorphism
and dimorphism would dissipate much of the mystery that hovers about the cause of
crystallization in general; and even, perhaps, illuminate many obscure parts of organic
science.

Towards the accomplishment of so desirable a result, an important step was made

ATOMIC HEAT TO CRYSTALLINE FORM. 107

by Mitscherlich, who from his elaborate researches deduced the well-known law, that
the same number of atoms combined in the same way produce the same crystalline
form, and that crystalline form is independent of the chemical nature of the atoms,
and determined by their number and relative position only. Carefully considered,
however, this law is seen to reveal merely the secondary or proximate cause of any
special crystalline form. It does not distinctly explain the phenomenon of iso-
morphism. Obviously in the power which aggregates the atoms, we are to look for
the prime cause of crystallization in general. Mlitscherlich’s law does not clearly
explain why different acids having different atomic weights and volumes, should,
when combined with the same base, present the same geometrical figure. According
to the atomic theory, the ultimate atoms composing the various chemical elements
differ in weight and volume. The numbers expressive of atomic weight are in some
measure indicative of atomic magnitude, otherwise the present great diversity in the
atomic numbers of the elements and their compounds could scarcely exist. And this
supposition receives very strong support from the well-known, but not duly appre-
ciated fact, that the atomic weight of a body may be very great, while its atomic
number is very small. Keeping in view this difference in atomic magnitude, it is
difficult to conceive, as indeed has been objected to Mitscherlich’s law, why arsenic
and phosphoric acids, whose respective atomic weights are 115 and 71, should, when
combined with soda, produce isomorphous compounds; why the seleniate and sulphate
of soda should be identical in form, when the atomic weight of selenic acid is 64, and
that of sulphuric acid 40, &c.

Again, it is a well-known fact that the same body may assume two or more
distinct and unrelated forms. Thus, carbon presents us with regular octohedrons in
the diamond, and six-sided plates in graphite, or plumbago. Sulphur is also dimor-
phous, assuming two incompatible crystalline forms. The minerals rutile, brookite
and anatase are distinct erystals of titanic acid. Carbonate of lime, too, expresses
itself dimorphously. Such facts as these show that as far as ponderable elements are
concerned, crystalline form is by no means the consequence of an invariable atomic
constitution. Moreover, isomorphism is compatible with a considerable difference in
the number of atoms. Thus, according to Mitscherlich, sulphur in one of its forms
is isomorphous with the bisulphate of potassa. The nitrite and the nitrate of lead
have the same octohedral figure, yet the latter compound has two atoms more of
oxygen than the former. Gmelin instances a number of similar examples.

Here, then, it remains to be explained why two or more acids having different
atomic weights, upon uniting with the same base, assume the same crystalline form;
why the same body presents us with examples of dimorphism, trimorphism, or even,
as in the case of water, of polymorphism; why some substances are isomorphous both

in the separate state and in combination; and lastly, why some substances replace
28

108 MEIGS ON THE RELATION OF

each other in compounds according to equal, and others according to unequal numbers
of atoms.

In 1809, from his own experiments, and those performed in company with Hum-
boldt, Gay Lussac clearly demonstrated that gases combine with each other by definite
volumes as well as by definite weights, and that the volume of a gaseous compound
is distinctly related to that of one or both of its constituents. Prout, Thompson and
others, by their researches, afterwards showed that this law embraced vapors, and
also the vapors of certain bodies which possess the elastic form only when combined
with permanent gases.

Recently Dr. Hermann Kopp of Giessen has attempted to extend the volume-theory
in another direction. He endeavors to show,—and with remarkable success,—that
all bodies in forming chemical compounds, unite by definite volumes in addition to
equivalent weights; that every body, whether elementary or compound, has a specific
atomic volume; that as atomic weights are proportional, so are atomic volumes; that
whilst atomic weight gives us the idea of mass, a crystal is the representative of a
regular and definite volume. From considerations of this nature he enunciates the
following law: “The specific weight of isomorphous bodies is proportional to their
atomic weights; or, isomorphous bodies possess the same atomic volume.’*

From the numerous examples adduced by Kopp, of the validity of this law, we
may legitimately infer that the phenomenon of isomorphism may be expressed by
saying, that many elementary and compound bodies tend strongly to assume the same,
or, at least, but a slightly differing volume. Furthermore, all crystallization is the
assumption of a form or regularly defined volume, the specifically regular outline or
contour of which is dependent upon the power and freedom of the aggregating force.
In the study of the volume of a body, then, is in all probability involved the study of
the cause of cohesive attraction, isomorphism, dimorphism, trimorphism, polymeric-
isomorphism, and all the interesting though obscure phenomena of crystallization.
Evidence of a very high character exists for supposing that identity in the arrange-
ment of atoms is the immediate predisposing cause of identity in form or volume.
Sameness in number does not appear necessary, for examples exist of isomorphous
bodies having unequal numbers of atoms. Reasoning in this channel, we are con-
strained to seek for the cause not only of isomorphism, but of all crystallization, in
that force, whatever it may be, which is capable of arranging an equal or unequal
number of atoms into the same volume. Now, many crystals, when once formed,
will maintain themselves unchanged under very varying external conditions. Hence
it may be inferred that the force which gave form to a portion of matter, which
created the crystal, so to speak, must exist with and in it, otherwise that form could
not be preserved. Just as in the organic world, the parent imparts its vital powers

ATOMIC HEAT TO CRYSTALLINE FORM. 109

to the ovum, which, through the processes of development, growth and nutrition, is
seen to act as a preservative power; when it departs, the mass of organized particles
which it vivified or animated is left a prey to surrounding destructive influences.

A crystal is composed of ponderable and imponderable elements;—the former
visible, gross and inert; the latter invisible, subtle, expansive and self-repellant. This
imponderable is caloric, and in one of its relations it constitutes the specific heat of a
body. Through all ponderable bodies it diffuses itself without exception, and accu-
mulates in quantities varying with the peculiar nature of the ponderable substance
with which it is combined. Here the question naturally presents itself to the
inquiring mind, as to the cuz bono of this caloric, its uses and relations. Its continued
presence, and well-known power and activity, as compared with ponderable matter,
authorize us to conclude that it is not without use, otherwise we accuse nature of
superfluity, of supererogation, which is manifestly unphilosophical. The combined

‘heat of a body, we know, is intimately connected with the existing condition or state
of aggregation of that body. Variation in the one is attended with alteration in the
other. Ice, water and steam are three very different forms of one and the same
gaseous compound. In all, the ponderable atomic constitution is the same, but the
amount of heat contained in each is very different. Diminish the heat of steam, and
you convert it into water; diminish it still further, and you convert the water into
ice. In this simple instance, then, and others could easily be furnished, we have
beautifully manifested the extraordinary influence of caloric upon the aggregation of
atoms. And yet with so simple and forcible an example before them—an example
embracing the three known conditions in which it is possible for ponderable matter to
exist—chemists still express themselves doubtfully as to the propriety of admitting
heat as an active constituent of bodies equally essential as their ponderable elements:

In his interesting paper above referred to, Kopp has given us numerous examples
which tend strongly to substantiate the relation which he contends for between iso-
morphism and sameness of atomic volume. Crystalline form and volume of atoms
are thus closely assimilated, if not, indeed, identified. Thus far concerning the pon-
derable matter. Philosophical confidence in the intelligential character and immuta-
bility of nature’s laws, and in the unerring exactitude of the results of those laws,—
in other words, implicit faith in the fundamental and truly scientific doctrine that
“nothing was made in vain,” here encourages us to advance at least one step further
in the cautious investigation of this intricate subject, by attempting to ascertain the
relation between the atomic volume and the imponderable element caloric surrounding
the atoms of a crystal.

In the following tables, where a number of elementary and compound bodies have
been grouped together isomorphously, it will be seen that for each group the numbers
expressive of the atomic volumes of the different substances of that group are either

110 MEIGS ON THE RELATION OF

almost identical, or related to each other in a simple, multiple proportion. A still
more evident similarity prevails throughout the numbers indicating the atomic heats
of the same bodies. Furthermore, a remarkable relation, in some instances more
-manifest than in others, is observed to exist between the atomic heat of a body and
its atomic volume.

The first column of the table contains the names of the substances, or, when these
are compound, their formule only; the second, their atomic weights upon the hydro-
gen scale; the third, their specific gravities; the fourth, the observed specific heats,
with the initials of the Experimenters attached; the fifth, the mean specific heats;
the sixth, the atomic heats obtained, after the manner of Dulong and Petit, by multi-
plying together the atomic weight and the specific heat; the seventh, the atomic
volumes, calculated according to the method of Schroéder and Kopp, by dividing the
atomic weight by the specific gravity.

To the first group belong sulphur, selenium and tellurium, substances closely con-
nected, not only by their own similarity in chemical properties, but also by that of

their analogous compounds.

nevertheless, in both atomic heat and volume.

Sulphur and selenium, although their atomic weights,
and therefore the magnitude of their atoms, differ so much, correspond very closely,

Hence, probably, the isomorphism of

the sulphates and seleniates, sulphurets and seleniurets—a point which I have not

been able to verify satisfactorily, in consequence of not being able to find upon record
any reliable specific heats for the seleniates and seleniurets, by which they might be
compared with the corresponding sulphur salts. The atomic volume of Pb S is 16.592;

that of Pb Se, 16.541.

The experiments of Mitscherlich show that the sulphates and

seleniates crystallize in right, rhombohedral prisms, at a very low temperature; in
octohedrons with a square base, at a mean temperature; and in oblique prisms, at a

very elevated temperature. Tellurium associates itself with this class by heat and
volume, as well as by chemical properties. Reasons exist for ranking oxygen with
these three elements. The probability of such a connection finds some support in the
fact that the combining measure of aqueous vapor and sulphuretted hydrogen is two
volumes, and that of the’oxide, sulphuret and telluret of ethyl, four volumes. An
atom of each of the two former substances, probably possesses a heat-sphere of the
same size. ‘The calorific envelopes of the atoms of the last three are also equal to
each other in extent, but twice as great as those of the former. ‘The relation of the
oxides and sulphurets is seen in the subjoined table.

Sulphuric and manganic acids are isomorphous. From this is inferred the iso-
morphism of the elements sulphur and manganese. Hence manganese is regarded as
the connecting link between the first three elements in the table, called the sulphur
class by Graham, and the next seven, named the magnesian class. Manganese is
regarded, therefore, as a sort of transition element, by which one group runs into or
is blended with the other,—a good exampie of the artificiality or unreality of scientific
classification in general. For the great plan of nature is, in the main, so uniform,
that the gaps which apparently dissociate the different parts are being constantly
filled up as new discoveries are made. Now, manganese has an atomic heat of 4.0059,
and an atomic volume of 3.466. ‘The first connects it, therefore, with both groups,
and the last with the magnesian series. The mean atomic volume of most of the
bodies in the second class, is a multiple by three of that of the first; the others bear
an equally simple relation. The correspondence of their elements in heat and volume,
is of itself sufficient to bring these two classes into one category. Moreover, their
more perfectly isomorphous protoxides evince a similar relationship in heat and
volume, as shown in the second table. It may be interesting to observe in this con-
nection that ice (HO) and protoxide of zinc, (ZnO) which differ not much in atomic
heat, have been seen to assume the same regular, six-sided form. Their complete
isomorphism, however, has not yet been established by exact measurement.

rank with sulphur, so the resemblance in their chemical relations between HO and
CuO is supposed to connect hydrogen with the group in question. It is curious to
observe that the atomic heat and volume of HO tend to confirm the notion of its
connection with the magnesian class.

Lime (CaO) probably occupies an intermediate position between this and the barium
series, blending them gradually together. This is very well shown in the table of
isomorphous salts, in the two groups of carbonates, where carbonate of lime as calc-
spar, assimilates, on the one hand, with the corresponding carbonates of magnesia,
iron, the mineral dolomite, &c., and on the other, as arragonite, identifies itself with
the carbonates of strontia, baryta and lead. The protoxides of barium, strontium,
calcium and lead, are nearly related in heat and volume. But the similarity of the
barium class to the magnesian is shown through their chlorides, where the corres-
pondence in atomic heat and volume is quite remarkable.

In the next two groups the numbers for atomic heat are the same throughout; as,
with one exception, are those for atomic volume. This is an exception in appearance
only, and not in reality, for its volume-number is just about double that of the others,
preserving, therefore, a simple multiple relation. This view finds confirmation in the
isomorphism of the oxides of tin and titanium, which compounds, as the table shows,
are sufficiently identified in heat and volume. Indeed the coincidence is still more
positive than at first sight appears. It will be seen that the specific heat obtained
by Avogadro for SnO, differs so much from the other three observations, that it may
very properly be omitted in calculating the mean specific heat of this body. This
procedure will give 6.9075 for the atomic heat of the oxide of tin. So the number
furnished by Hermann for the specific heat of TiO, may, with equal propriety, be
rejected in ascertaining the mean specific heat of titanic acid. We thus obtain 6.9417
for the atomic heat of this latter substance. These two numbers may be considered
as identical. I may here remark that a similar analysis of the whole table would
lead to results still more striking than those indicated. I have preferred, however,
to give all the recorded specific heats, with the mean for each elementary and com-
pound substance, from which to calculate the atomic heat, because in this manner is
avoided the confusion of so many analogous numbers for any body, and still more
because I regard the results obtained in the table as approximations merely to a great
general truth or law in nature, which yet remains to be demonstrated by a logical

ATOMIC HEAT TO CRYSTALLINE FORM. 117

synthesis of scientific facts. In these investigations it must, for the present, be kept
constantly in view, that the numbers obtained by experiment for the specific heat of
different bodies, do not accurately express the amount of caloric combined with the
ponderable matter of those bodies. The specific heat is only a portion of the whole
quantity of combined heat; and, as Regnault has shown in his second memoir,* the
obstacles to be overcome in obtaining the specific heat of any substance, with perfect
accuracy, are exceedingly great, if not, indeed, insurmountable with our present
appliances.

From the isomorphism of their double chlorides, Dr. Clark is inclined to associate
the. tin and platinum classes. The relation of these two series in heat and volume
lends considerable support to their presumed affinity. According to Breithaupt, CdS
is isomorphous with the alloy IrOs. The atomic volume of either iridium or osmium
is to that of CdS as 1:14. Palladium, although not generally arranged in this series,
appears here to find its natural place.

Tungsten and molybdenum correspond in heat and volume. The tungstates and
molybdates are isomorphous, as their agreement in atomic volume sufficiently indicates.
I have not been able to find upon record the atomic heat of these salts. Their sup-
posed isomorphism is confirmed by the following comparison :—

The bisulphurets of tin and molybdenum, which present some resemblance in their
_ physical constitution, have atomic heats but little different. The bisulphuret of iron
differs very much from these in its characteristics, and we find that its atomic heat
is also very different. (Regnault.)

In the metallic state gold and silver are isomorphous. Their relationship in heat
and volume is very obvious. I have followed Gmelin in adopting 199 as the atomic
weight of gold. If we assign it 99.6, as do some of the chemists, and halve the atomic
weight of silver, for the cogent reasons advanced by Regnault, the above relation
still holds good. Or, if we reject the suggestion of Regnault, it will be found that in
heat and volume silver is the exact multiple by two of gold; so that in either case,
the simplicity of relation (which in the present state of our knowledge of these
subjects is all that we can contend for) is still preserved. Sodium allies itself with
silver, as shown by the resemblance in atomic volume of their carbonates, sulphates,
nitrates and chlorides. In all this series, as far as the specific heats have been
obtained, the same correspondence in heat and volume is evident.

The atomic volume of sodium, as given in the table, is about one-half that of potas-
sium. These volumes would be equalized by doubling the atomic weight of sodium ;
and it is interesting here to observe that this alteration has been proposed by Dr.
Clarke from theoretical considerations of a different character. The simplicity of
relation is therefore evident.

It is well known that the potassa and ammonia salts exhibit very complete iso-
morphism. This, indeed, might be inferred from the comparison of the nitrates of
these bases, as shown in the table. Hence it is probable that potassium and ammo-
nium, as has been suspected, are themselves isomorphous, notwithstanding that one
atom of nitrogen and four atoms of hydrogen replace one of potassium in combination.
I have not the data to compare them, either by heat or volume.

Phosphorus, arsenic, antimony and bismuth, constitute a natural group to which
nitrogen is thought to belong. For the first three the atomic heat is about the same;
the number for bismuth is about one-half that of the others. The relation between
the atomic volumes is not so evident. If we follow the example of many of the
Kuropean chemists, and halve the atomic weights of phosphorus, arsenic and antimony,
a tendency to multiple relations between the atomic volumes will become more
evident. This tendency is developed in their isomorphous compounds.

ATOMIC HEAT TO CRYSTALLINE FORM. 119

The isomorphous and calorific correspondences between the different bodies com-
posing each of the several groups of compounds, are sufficiently obvious to require no
comment.

In most of the standard chemical works, the elements have been classified isomor-
phously, not so much from any proof that they individually present, as from the iso-
morphism of their compounds. The law promulgated by Mitscherlich naturally leads
to such supposition and consequent classification. It must not be forgotten, however,
that comparatively few of the elementary bodies are crystallizable, and that, therefore,
we are in great measure deprived of the positive and demonstrative proof of the
isomorphism of all the elements. Nevertheless, two-thirds of the crystallizable
elements belong to the regular system, and are hence isomorphous the one with the
other. Of these, however, some crystallize in other forms, under which they are
isomorphous with elements belonging to other groups, as the Rhombohedral and Right
Prismatic. Hence, from their arrangement into various isomorphous classes, and the
resemblance between and apparent correlation of these classes, we fairly, though
indirectly, infer, as highly probable, that the chemical elements, under certain favor-
able conditions, are capable of assuming the same form. Now, the approximation of
many of these elements, in atomic heat and volume, certainly seems to confirm the
reality of this isomorphism. It will thus be seen that the capacity for heat of ele-
; mentary atoms is related through isomorphism only. Moreover, it will be observed
among compound atoms, that although similarity in chemical constitution is, in
general, accompanied by sameness in capacity for heat, yet examples: exist of differ-
ently constituted bodies also presenting this similarity. This is an important fact
and one worthy of close consideration, since it probably explains why one atom in a
compound body will replace two or more atoms in another with which it is isomor-
phous. Thus Cu,S and AgS are isomorphous. Here two atoms of copper replace
one of silver, and yet retain the same form. Now the atomic heat of copper is about
half that of silver. The atomic heats of the two sulphurets are as follows :—

At. Heat. - At. Volume.
Cu,S : ‘ : 9.647 : ; 3 13.528
AgS : 5 4 : 9.258 ; ; “ 18.116

Even if we adopt Regnault’s suggestion, before alluded to, and write both substances
according to the formula R,S, the numbers for atomic heat will still be nearly the
same.

Bisulphuret of iron Fe,S, is dimorphous. In the mineral Spirkise it is isomorphous
with arsenide of iron Fe,AsS,. In the pentagonal dodecahedron of the regular system
it is isomorphous with cobalt glance, CO,AsS,. Again, Cd,S, and Ni,S, are each
isomorphous with Ni,As. Thus it would appear that one equivalent of arsenic is

isomorphous with two of sulphur. Now the table shows us that the atomic heat of
31

120 MEIGS ON THE RELATION OF

arsenic is about twice that of sulphur. The atomic heat of Fe.8, is 15.60384, of
Fe,As8,, 16.35392. The cyanides replace the chlorides, three atoms occupying the
space and performing the function of one. The atomic heat of cyanogen is 14.4222,
that of chlorine, 14.4627.

We come now to inquire why the atomic heat and volume in many of the isomor-
phous groups are not absolutely identical. Many bodies called isomorphous are
not strictly so. Their corresponding angles sometimes vary several degrees. A
variation of 59’ has been observed by Mitscherlich in the analogous angles of
different specimens of the same salt. In the sulphates of barytes and strontia the
angles of the rhombs differ by 2° 48'; in the carbonates of lime and magnesia by
2° 36'; and in the sulphates of zinc and magnesia by 38’. Inequalities also exist
between the axes of such plesimorphic bodies. Now the interdependence of crystalline
condition and atomic volume has been well and beautifully shown by Kopp, as the
result of an attentive study of the various classes of plesimorphic and strictly isomor-
phic compounds. That careful physicist found that variations in the individual
angles of a crystal were accompanied by corresponding variations in its atomic volume.
But the angular value of a crystal depends upon the proportions between its axes, and
these cannot suffer alteration without changing the density, and, consequently, its
specific gravity—alterations necessarily preceding variation in atomic volume.
Elongation of the principal axis increases the atomic volume; thus, step by step, we
are led to the conviction that crystalline form is inseparably connected with, and
dependent upon, peculiar axial proportions. Whatever modifies these proportions in
a definite manner, must be considered as the ultimate cause of the plesimorphic
differences referred to above. In this connection, the observations of Mitscherlich,
Fresnel and others, upon the application of heat to crystals, may be studied with much
advantage, as they are well calculated to lead to results as positive as they are impor-
tant. According to these gentlemen, when crystals not belonging to the regular
system are heated, their axes expand unequally and change the magnitude of their
angles. Crystals of the right prismatic system have their three axes expanded differ-
ently. In arragonite, on raising the temperature from 32° to 212°, the inclination
of the lateral faces increases by 2' 46”, and that of the terminal faces diminishes by
5' 29"; gypsum is more expanded by heat in the direction of the principal axis than
in that of the lateral axes. In bitter spar, the obtuse angle of the primitive rhombo-
hedron diminishes when the temperature is raised from 32° to 212° by 4' 6”; in
ferruginous bitter spar, by 3’ 29”; in iron spar, containing a considerable quantity of
manganese, by 3’ 31”; and in pure iron spar, by 2’ 22”. In crystals of the rhombo-
hedral system, the expansion is the same in the directions of the three secondary
axes, but different in that of the principal axis.* But the positive and methodical
influence of heat in changing the density, axes and angles, and, therefore, the form

*Gmelin. Hand-Book of Chemistry, Cavendish Society edition, vol. i. p. 233.

ATOMIC HEAT TO CRYSTALLINE FORM. 121

of a crystal, is beautifully and conclusively shown in the following example: Calca-
reous spar, heated to 180° F., has its specific gravity decreased in the proportion of
1: mm; its principal axis expanded by 0.001961; and each horizontal axis contracted
by 0.00056 ; in consequence of which the obtuse angles of the primitive rhombohedron
diminish, and the acute angles increase by 8’ 34". Now, according to Kopp, when
its principal axis = 0.85440, and its obtuse angle = 105°.5’, the specific gravity
of calc spar is 2.7220. When heated, its specific gravity becomes 2.71675, and its
atomic volume passes from 232.36 to 232.80; or, in other words, a modification of
form ensues. ;

The phenomenon of dimorphism presents us with many examples strongly confirma-
tory of the significant connection, here indicated, between form and capacity for heat.
Still more do they conduct us to some positive notions concerning the active agency
of caloric in producing crystalline form. “Crystals formed at one particular tempe-
rature,” says Gmelin, “and then exposed to that temperature at which crystals of a
different kind are produced, often lose their transparency, and, without alteration of
external form, become changed into an aggregate of small crystals of the latter kind.
We may therefore imagine that the atoms of the solid crystal displace one another in
such a manner as to bring about the particular arrangement which they are disposed
to assume at the altered temperature, the new arrangement belonging to a different
crystalline system.”* Carbon, as found in the diamond, which belongs to the regular
system, has a different atomic heat from carbon as found in rhombohedral graphite.
Tn fact, all the varieties of carbon differ in the same respect, as shown in the following

calorific capacity of a body and its degree of aggregation.

If sulphur be melted and allowed to solidify at 230° F., it assumes the form of an
oblique rhombic prism; if it be made to crystallize from its solution in bisulphuret of
carbon or oil of turpentine, at a temperature under 100°, it appears in the shape of
octohedrons with rhombic bases. According to Graham, the crystals of sulphur
produced at the higher of two temperatures, become opaque when kept for some days
in the air, and pass spontaneously into the other form, in consequence of a new
arrangement of atoms; at the same time their transparency is destroyed, because a
mass of crystalline particles takes the place of one crystal, thus causing the light to
be refracted in various directions. The crystals produced at the lower temperature
are disintegrated and changed into the other form by a moderate heat.

As in the case of carbon, the varieties of sulphur differ in atomic heat.*

If chloride of calcium and carbonate of ammonia be mixed together, and the solution
brought to a temperature of 50° F., the precipitating carbonate of lime will take the
form of rhombohedric crystals, as in calc-spar; if the solution be kept at 150°, the
crystals appear as cubes, as in arragonite. If these cubic crystals are allowed to
remain in the liquid, while the latter is gradually cooling, they are slowly but com-
pletely converted into calc spar.t

According to Fownes, green sulphate of iron crystallizes in two different forms, and
with two different proportions of water, according to the temperature at which the
salt separates from the solution.{

A prism of arragonite, exposed to the flame of a spirit-lamp, decrepitates at a low
red heat, and breaks up into numerous minute rhombic grains of calc spar. Melted
chalk, on cooling into marble, exhibits a rhombohedral structure. From these facts
it appears, that while a low temperature gives to CaO, CO, the form of calc-spar, a
higher temperature is necessary to produce arragonite,—which latter is indeed formed
only between very narrow thermometric limits. Below are the atomic heats of
different varieties of carbonate of lime.

Carbonate of strontia precipitates in an indeterminate form, when chloride of stron-
tium is decomposed by carbonate of ammonia in the cold. When heated, it takes the
form of arragonite. But the chlorides of barium and lead, when mixed with carbo-
nate of ammonia in the cold, respectively precipitate PbO, CO, and BaQ, CO, in the

form of arragonite. Now the latter carbonates have a somewhat higher atomic heat
than SrO, CO,.

If hot, concentrated caustic potash be saturated with protoxide of lead, the latter
separates in the shape of rhombic octohedrons having a yellow color; as the .
solution cools, however, red, crystalline scales are deposited on the first. If the red
crystals be heated, they take the first form and also the yellow color.*

Anatase and rutile, two forms of oxide of titanium, though both belonging to the
square prismatic system, have incompatible angles, which assign to each a different
primitive form. They differ in atomic heat and volume.

Bisulphuret of iron, as common iron-pyrites, belongs to the regular system; as
white iron-pyrites, to the right prismatic system,—the latter being of a paler yellow
color and much softer. Breithaupt thinks that the former has been formed at a
higher temperature than the latter. The atomic heat of the common variety is
7.5480; of the white variety, 7.8854.

Sulphate of nickel (NiO, SO;7Aq.) is trimorphous. It crystallizes below 59° F. in
right rhombic prisms; between 59° and 68° F. in acute octohedrons with square bases ;
and above 86°F. in oblique rhombic prisms; also in forms belonging to the right,
square and oblique prismatic systems. The right rhombic prisms, after exposure to
sunlight for a few days, are found to be composed of square-based octohedrons, often
several lines in length. The sulphates of zinc and magnesia exhibit similar pheno-
mena. They assume different forms, according as they are made to crystallize at a
high or a low temperature,—manifesting, as Mitscherlich has shown, very peculiar
and interesting changes with variation of temperature.+

According to Frankenheim, sal ammoniac, which generally crystallizes in regular
octohedrons, appears at higher temperatures to assume forms belonging to the right
prismatic system.]

When the rhombohedrons of KO, NO; are heated considerably above 100° C., they
change into prismatic crystals. A hot solution of KO, NO, deposits prismatic crystals
when slightly cooled; at a temperature of 14° F., however, rhombic crystals begin to
appear. (Frankenheim.)

Protiodide (red iodide) of mercury sublimes at a low heat, and also separates from
solution in square, prismatic tables of a scarlet hue; at a higher temperature, rhombic
tables of a sulphur-yellow color are formed. As often as they are heated, the red
crystals turn yellow, and again become red as they cool. (Gmelin.)

Examples of this kind attest the strong, controlling influence of temperature upon
isomorphism. We see that whether a body shall be isomorphous with a second or 9
third, is mainly determined by temperature. “Les isomorphismes chimiques d’un

méme corps peuvent done changer completement avec la température.”* Changes in
the form of a body correspond to variations in its combined heat.

Many crystallizable bodies assume a peculiar state of aggregation known as the
vitreous condition, which may be considered as a variety or modification of dimorphism.
The binarseniate and biphosphate of soda resemble each other strongly in physical
and chemical properties. When exposed to the same heat, the first solidifies, on
cooling, into a white opaque mass composed of interlaced crystalline fibres, while tie
second is converted into a transparent, colorless glass. While undergoing these
changes, the arseniate discharges sensibly more heat than the phosphate; hence,
probably, the glassy condition of the latter salt is due to the retention around its
particles of a portion of the heat of fluidity.+

Ordinarily sugar has a granular or crystalline structure. When melted and allowed
to cool slowly, it assumes a glassy condition and manifests very different physical
properties. If, while still soft and viscid, (as at the temperature of 100°,) it be rapidly
drawn out into threads, a large quantity of heat is liberated, and the sugar separates
into minute granules of a pearly lustre.

That the vitreous condition isin some manner connected with the amount of heat
accumulated around the ultimate particles, is shown by the fact that glass kept soft
for a long time, gradually loses its heat and is converted into a substance known as
Reaumur’s porcelain, in which it assumes different characters. The crystalline and
amorphous states of the same body differ to a certain extent in their properties; the
former being in general harder, specifically heavier and less soluble than the latter,
in which the atoms are placed farther apart than in the first. Graham also affirms
that the amorphous condition is accompanied by a larger quantity of combined heat
than the crystalline.

Arsenious acid sublimes as a transparent glass with a light, yellow tint. By
exposure, the vitreous mass gradually changes into a congeries of small octohedral
erystals, and becomes opake, milk-white, and slightly altered in solubility and density.
According to H. Rose, if the vitreous mass be dissolved in hydrochloric acid, each
crystal as it separates emits a flash of light. Regnault, in his second memoir, says,
“‘Vacide vitreux (arsenious) devient promptement opaque a la température de 100°.”
The vitreous acid has an atomic heat of 15.0796; the opaque, 15.2064. Now,
Guibourt has shown that the specific gravity of the vitreous acid diminishes during
the change to the opaque form, from 3.785 to 3.695; and that the latter dissolves
rather more abundantly both in hot and cold water than the transparent. This is an
exception to the ordinary cases, for the change from the amorphous to the crystalline
form is accompanied generally with increased density and diminished solubility. It
is interesting here to observe that the difference in atomic heat, though very small, is

in favor of the opaque variety—another departure from the usual rule, the opaque
form, having commonly less than the transparent or vitreous.

The limits to which I have assigned this paper, prevent me from here introducing
in detail many facts similar to the above. I would, however, especially refer the
reader to the first volume of Gmelin’s Chemical Hand-Book, where, in the article on
Amorphism, have been collected from the writings of Rose, Fuchs, Regnault, Frank-
enheim, Marchand, Scherer and others, many valuable and instructive examples of
the modifying influence of caloric upon the state of aggregation, form and properties
of bodies. These constitute but a few of the many examples which a progressive
science is daily placing upon record, to be used hereafter for the loftiest purposes of
philosophical generalization. They are worthy of, and will amply repay, the closest
investigation, since they conduct us to the very threshold of Nature’s secret laboratory,
promising to lay bare that for which the human mind, through all ages, has so fondly
and unceasingly longed—a knowledge of the primary physical cause of all natural
phenomena.

Nature annually performs for us, on a grand scale, an experiment at once simple,
beautiful and instructive. I allude to the formation of snow crystals. In this process
the crystallizing material is the same throughout all the varieties of form, but the
accompanying temperature varies. In his excellent work on the Arctic Regions,
Scoresby has classified the many forms of snow-flakes observed by him in his voyages
to the North, and given a table showing the different temperatures at which different
crystals were seen to fall. He refers the varieties of snow crystals, for their cause,
to variations in atmospheric temperature. My own observations made during the
past winter, lead to the same conclusion. When, after variable weather in the winter
season, the cold has set in steadily for several days, gradually condensing the aqueous
vapor and obscuring the heavens, the wind constantly blowing from the same point,
and the upper atmospheric currents, as shown by the course of the clouds, having the
same direction as the lower, I have very generally found that while the thermometer
indicates nearly the same reading, the crystals of snow that fall under such circum-
stances have the same or but slightly differing forms. Any marked change in the
height of the mercurial column is very commonly followed by some manifest change
in the snow-figures. It is true that very different and unrelated forms are often
observed to fall simultaneously ; but reasons well known to the climatologist, render
it very probable that they have been generated in atmospheric currents or strata
differing in temperature. Indeed I suspect that a snow-crystal, by passing through
variously heated currents of air, may have its form considerably altered as it descends
towards the earth. By holding the partly-closed hand over a crystal, so as to increase
the warmth of the surrounding air, I have, on several occasions, noticed very remark-
able modifications of form. Mr. James Glaisher also speaks of this phenomenon, in

126 MEIGS ON THE RELATION OF

a communication directed to the Editor of the Illustrated London News, (Feb. 24th,
1855.) He says, “In conclusion, I may be forgiven if I remark, for the benefit of
the inexperienced, that the crystal subjected to the warm influence of the proximity
of the observer, not unfrequently alters in form before it sensibly begins to melt. I
have myself more than once drawn a specimen on its first descent, verified it to my
satisfaction, and passed on to others; after the lapse of perhaps a quarter of an hour
or more, I have been surprised by witnessing, as I imagined, a new specimen occu-
pying the precise spot of the former. In each case, however, careful observation
proved to me that it was no other than the crystal I had already drawn, and that the
dissimilarity arose from a general simplification of the figure caused by the subsidence
of the groups of prisms surmounting the apex of the rays, the rounding of the edges
of those prisms which remained, the subsiding of two or more prisms into one, and
the elongation of spiculze which formerly served as the axes of prisms.”

Very peculiar changes may be witnessed by studying the gradual wasting of a snow ~
crystal in consequence of an increasing warmth of the air. Thus I have seen a
hexagonal lamella similar to fig. 87 of Scoresby’s plates, change into one like fig. 28,
then resemble a star, (fig. 13,) and ultimately leave only its three axes as the skeleton
or fundamental portion upon which the body of the crystal was erected. ‘These axes
finally disappeared, the destruction beginning at their apices and ending at their
common centre or j unction, thus following an order the reverse of their formation.
An exact statement of the amount of heat combined with each variety of snow-crystal
would constitute a valuable addition to our present stock of knowledge.

Thus, then, we learn that the particular system or genus in which a body crystal-
lizes, is mainly determined by the temperature at which solidification takes place.

Dimorphism is intimately associated with isomerism. Both phenomena furnish us
with instances of the positive and active relation which atomic heat bears to both the
form and properties of bodies. Some isomeric substances, though agreeing in ultimate
ponderable compositions, differ completely in atemic weight, and every other respect ;
in others, both the atomic weight and elementary compositions are the same ; in others
the atomic weights are the same and their molecular arrangement different; but, in
all, as far as I can ascertain, their atomic heats are different. Phosphoric and pyro-
phosphoric acids are alike in composition but dissimilar in properties: the second acid
is simply the first in a state of fusion. Racemic and tartaric acids are very similar in
properties and chemical relations, and, according to Mitscherlich, isomorphous. When
heated, they each form three classes of salts, but are so modified that each, upon unit-
ing with the same base, in the same proportion, produces a different compound. When
destructively distilled, both give rise to the same pyr-acid. It is well known, that
every organic acid has its corresponding pyr or fire acid.

“When the group of chemical molecules are differently arranged,” says Kane, “the

ATOMIC HEAT TO CRYSTALLINE FORM. |. 127

various differences in color, density, solubility and figure which belong to dimorphous
bodies are produced; but when the difference of arrangement extends to the chemical
constituents of these molecular groups, independent but isomeric bodies are produced.”*
It would thus appear that isomorphism, dimorphism, polymorphism and isomerism
are immediately dependent upon a peculiar arrangement of atoms, and of molecules
composed of two or more atoms. From the inherent tendency to such arrangement,
probably results the binary method of combination in both the organic and inorganic
worlds. Now, from all the foregoing facts, we have seen that when bodies agree in
fourm and properties, they also approximate in atomic heat. When bodies assume two
or more forms, their chemical properties differ, as do also their atomic heat. Bodies
having the same composition, but differing in structure (as in all probability isomeric
bodies do), and consequently in properties, differ aiso in atomic heat.

Throughout this series, a remarkable parallelism is evident, between atomic heat on
the one hand, and arrangement of atoms, and forms and properties of bodies on the
other.- It is very generally true, that bodies having the same form, have also the
same properties; and that difference of form is accompanied by corresponding differ-
ence in properties. Very probable is it, therefore, that not only form, but also color,
specific gravity, solubility, hardness, &c., are all dependent upon certain arrangement
of atoms. But the arrangement of particles, necessarily pre-supposes an arranging or
motor agent, which constitutes the ultimate physical cause of crystallization. As the
attractive force, so grandly displayed in the solar system, must ever be present and in
action among the planetary bodies of that system, that they may be retained in their
accustomed orbits; so the atoms of a crystal require the continued presence and equal
action of the arranging power, to maintain them in that relative position necessary to
the preservation of the general form. Hence we infer, that the arranging cause must
be a motor power, and always present. Furthermore, if it can be shown that such an
agent exists in a crystal, a strictly logical method should prevent us from seeking else-
where for the cause of peculiar atomic arrangement, and all the physical phenomena
manifestly dependent upon it.

Now we have seen that caloric is always associated with the ponderable matter of a
crystal, and that it is positively related to crystalline form, and hence, to arrangement
of atoms upon which form depends. It only remains to adduce some proof of its
efficient activity. The experiments of Fresnel,t Baden Powell,{ Addams§ and others
show conclusively that heat is self-repellant. Moreover, a careful analysis of the en-
tire series of phenomena, which, in the aggregate, constitute the natural history of
caloric, tends strongly to establish the fact that heat is a most powerful motor agent.
Indeed, the ancients, with very few exceptions, contended (vaguely, however, and un-

supported by experimental proof,) that caloric was the prime mover and cause of all
natural phenomena. A forcible writer of our own time and place, maintains this doc-
trine with an imposing and comprehensive array of argument.”

The following brief resume of facts, connects itself with the question under con-
sideration :—

Cohesion varies inversely with the temperature, generally increasing as the latter
diminishes, and vice versa. Heat expands bodies, rendering those that were hard,
soft and even liquid and gaseous. This change in bulk and condition, corresponds to
an increased separation of atoms. A sufficient reduction of temperature solidifies all
bodies. Liquids and gases may be regarded as solid matter, plus a certain amount
of caloric, the amount varying with the species of matter. Otherwise, the particular
temperatures at which bodies undergo these changes would not be so very different,
nor would they always be constant for the same body. Heat is certainly the cause
of fluidity, gasefaction and evaporation. The most permanent gases—those which
manifest the greatest resistance to being deprived of the gaseous form, by external
pressure and cooling—are those in which the most intimate union exists between the
ponderable matter and heat. Gases contain more heat than liquids, are more elastic,
therefore, and manifest a tendency to expand without limit, if not opposed by ex-
ternal obstacles; liquids contain more heat and are more mobile than solids, which
contain least of all the forms of aggregation. Gases by their refinement, superior
activity and expansive power, pass through openings impervious to liquids; so liquids
escape through openings impassable to solids. Ponderable matter is made to occupy
a larger or smaller space, according as it is combined with more or less of the repellant
material—caloric.

Dr. Black, whose researches may be considered as constituting the foundation of
the science of thermotics, showed, quite clearly, that the structure and properties of
solids varied according as their combined heat was increased or diminished. Accord-
ing to this observer, the malleability and ductility of metals depend upon the quantity
of latent heat they contain. When hammered, they become red hot in consequence
of the disengagement of heat; at the same time, while their density, and consequent-
ly specific gravity increase, their malleability diminishes and they become brittle.
Malleability is restored by heating. In the first volume of his valuable Hand Book
of Chemistry, Gmelin has given numerous and very striking instances, showing that
heat imparts to many ponderable bodies particular colors, which vary according to
the quantity of heat contained in the bodies. Those metals which increase most in
specific heat, when exposed to an elevated temperature, are found to have their rate
of expansion also most rapidly increased. According to Dulong and Petit, when the

increased capacity for heat is about one-tenth, the increase in expasion amounts to
one-hundredth. But we cannot conceive of this expansion taking place without the
atoms being moved farther apart, thus increasing the volume. Coincidently with this
change, and as a proof of its reality, we find the specific gravity of the metal diminish-
ed. Hence it is, that the capacity for heat of any body increases with the temperature ;
- for the arrangement of the atoms at greater distances from each other must necessarily
afford more space for the accumulation of caloric around the particles. Thus the
specific heat of copper is reduced, by violent hammering, from 0-095 to 0-935; but
raised again by ignition, to 0.0949. Lead and tin, on the contrary, which do not in-
crease in specific gravity under the die, likewise suffer no diminution of specific heat
by pressure. The specific heat of soft bell-metal, (Cus) Sn) which has a density
of 86843 is 0:0862, while the same metal hardened, in which state its density is
8:5797, has a specific heat of 00858. (Regnault.) The more dense a body is, the
ereater is its specific gravity and the less its specific heat. A beautiful example is
given by Regnault in the case of precipitated silver. The specific heat of this sub-
stance varies with the degree of condensation, as shown by the following results de-

termined by the method of cooling :—

Peroxide of iron and peroxide of nickel when strongly ignited, increase in density
and diminish in specific heat. The varieties of carbon present the same result. The
interesting experiments of Messrs. Hopkins, Fairbairn and Joule, upon the effects of
extreme pressure, demonstrate that the temperature of fusion increases in proportion
to the pressure to which the fused mass is subjected. In employing a pressure of
about 13,000 lbs. to the square inch, on bleached wax, they found that increase in
the temperature of fusion was not less than 30° F., about one-fifth of the whole
temperature at which it melts, under the pressure of the atmosphere.* Such facts, I
may say in passing, militate strongly against the generally received, though probably
erroneous theory of the exalted calorific condition of the centre of our planet.

But the active agency of caloric in affecting specific gravity, is seen by comparing
compound bodies with the elements of which they are composed. Thus hydrogen
and chlorine unite, without condensation, to form hydrochloric acid gas. The specific
gravity of one volume of hydrogen is 69:26; of one volume of chlorine, 2421-6; and
of one volume of hydrochloric acid gas, 1247-4 ; the mean of the two former numbers.
The specific gravity of hydrogen is about 36 times less than that of chlorine; its

130 M#IGS ON THE RELATION OF

elastic force, on the contrary, is exceedingly great; while cold alone, or a pressure of
but four atmospheres is sufficient to condense chlorine. The expansive power of
hydrochloric acid gas, is equal to the pressure of 40 atmospheres, at the temperature
of 50°. Now the atomic heat of H is 21:2064; of Cl, 14-4627; and of HCl, 28-9263.
Four volumes of HCl must contain as many atoms as two volumes of H, or of Cl;
or, two volumes of HCl contain as many atoms as one volume of H or Cl. But one
volume of H contains half an atom, hence one volume of HCl must contain one-fourth
of an atom, which must therefore be surrounded by twice as large a heat-sphere as
the half-atom of H. Such facts authorize us to conclude, that chlorine in combining
with hydrogen has its specific gravity reduced, in consequence of abstracting from the
latter gas an additional quantity of caloric, by which its particles are separated further
from each other and made to occupy a larger bulk. This supposition will also account
for the change in elasticity. The union of iodine, bromine, cyanogen, &c., with hydro-
gen is accompanied by a similar reduction in specific gravity, and alteration in physi-
cal and chemical properties. When hydrogen unites with sulphur, phosphorus, and
arsenic-vapors, and with carbon, in different proportions to form, respectively, sul-
phuretted, phosphuretted, arseniuretted, and light and heavy carburetted hydrogen
gases; with oxygen to form aqueous vapor, and with nitrogen to produce ammonia,
the resulting specific gravities of these respective compounds is very much less than
the sum of those of their constituent elements, The volume and elastic force of these
gases are also altered in a remarkable manner.

According to Graham, the more nearly bodies agree in composition, they are the
more likely to act as solvents of each other, or to be miscible in the liquid form.* But
we have seen that in both compound and elementary bodies of the same atomic con-
stitution and of like chemical constitution, the specific heats are in the inverse pro-
portion to the atomic weights. In this connection, I may refer to those numerous
and interesting examples of change in the solubility of bodies after being heated,
although their composition remains the same. Alumina, binoxide of tin, sesquloxide
of chromium, and other metallic peroxides, and certain salts, such as silicates, tung-
states, phosphates, antimoniates, &c., after exposure to a temperature just below red-
ness, lose their solubility in acids. In its cubic form, the bisulphuret of iron resists
the action of both air and water; but in its right rhombic form, when exposed to
moist air, it absorbs oxygen with great avidity, and is converted into a crystalline
mass of copperas.; Spontaneous ignition often accompanies those changes in solubility,
and generally just as the body is passing from the soluble to the insoluble state. “Je

In the Annales de Chimie et de Physique, (ler ser. t. 70, p. 407,) Gay-Lussac has
published some observations upon certain bodies whose solubility he shows to be deter-
mined by temperature alone. These observations lead, moreover, to the supposition
that all spontaneous precipitations are due to differences in temperature.

Many elementary bodies in uniting to form compounds, suffer a contraction in
volume. Now, M. Filhol has shown, that in those compounds whose chemical
properties are very analogous, the co-efficients of contraction are sensibly the same.+
Analogous properties seem to be associated with analogies in calorific condition.

It would be superfluous to adduce other examples of the active character of caloric.

From the laborious and carefully conducted experiments of many eminent physi-
cists, we may infer that in the most, if not all bodies, the combined heat varies to a
greater or less extent in different specimens. Examples of this we find in carbon,
sulphur, &c. Accompanying this variation, and in all probability caused by it, we
find a change in form, condition, physical and chemical properties and the like.
Indeed it is difficult to conceive how any change, even the slightest, in the heat of a
body, could be unaccompanied by some alteration in the ponderable matter. The
extreme sensitiveness of heat or caloric is evinced in every chapter of its endless
history. It is very rational to suppose, therefore, that the influence of caloric in
moulding ponderable matter into definite forms, must in a certain measure vary with
the degree of aggregation of the body, which state of aggregation is indeed in great
measure contingent upon the amount of caloric itself. Increased aggregation is gene-
rally an indication of diminished calorific capacity. In colcothar and the diamond
we have beautiful examples of this fact. In condensing very strongly, a body often
completely loses its most characteristic chemical properties. Heat acting upon two
dissimilar pieces of metal soldered together, gives rise to electrical phenomena; acting
upon water, produces motor effects. From such conspicuous examples we are forced

to conclude that any variation in the ponderable substratum or medium upon which
a definite amount of caloric is made to act, or im the attending circumstances by
which the body is surrounded, must necessarily produce a variation in calorific effects.
Hence the want of absolute identity in the crystalline form of many bodies which
are really isomorphous. Hence, too, the discrepancies occasionally met with between
the atomic volume of a body and that of the other members of the group to which it
belongs. For atomic volume is calculated from relative weight and specific gravity ;
as the latter two vary, so must the former. Now the specific gravity of a body may
vary according as it is adulterated or not with matters lighter or heavier than itself,
and having naturally different quantities of heat; or the body itself may, in different
states, possess different quantities of combined heat. This view will explain the
fortuitous coincidences in form accompanying dissimilarity of properties and compo-
sition; and, also, why certain elements manifest isomorphism in their analogous
compounds, and yet cannot be shown to be isomorphous in their elementary state.
For the mathematico-chemical investigations of Kopp lead us to suppose that the
primitive atomic volume of an element suffers a considerable change in its different
combinations,—the combining volume bearing in most instances a simple or multiple
relation to the primitive. Hence a body may have two or more atomic volumes as
well as crystalline forms, which, indeed, we should infer a priori. _

We know very well that a certain elevation of temperature may so affect the
molecular structure of a body as to destroy its identity or individuality,—changing
its form, color, properties, &. This molecular change is nearly always accompanied
by a simple multiple change in the equivalent of a body, and of course in the atomic
volume. It seems very probable, therefore, that the different forms which certain
elementary bodies are known to assume, are intimately connected with diversity of
equivalent volume. We may suppose that sulphur has a larger and more intricate
volume when it takes the complex form of bisulphate of potassa, than in its ordinary
simple form. So, likewise, we may suppose that when one equivalent of chlorine
replaces one of cyanogen, or two of manganese in combination, it must have a
varying volume, and consequently a varying form, in compound bodies. According
to Graham, the tendency of discovery is to bring all the elements into one class,
either as isomorphous, atom to atom, or with the relation to the others which sodium,
chlorine and arsenic exhibit. In this connection, the sameness of atomic heat of the
elements, the similarity of many of the atomic volumes, and the simple relationship
of the others, as shown in the table, are significant facts.

If we ignore the materiality of heat, and deny that it is as essential to the compo-
sition of bodies as ponderable matter itself, the changes in form, properties, &., which
these bodies undergo, are without explanation. If, on the contrary, we follow the
evidence of our senses, and acknowledge the substantiality of caloric and the extent

and dignity of its influence upon the self-inert bases with which it is combined, we
open a channel for the hopeful investigation of cause and effect. Changes in the
properties of things must be preceded by compositional and structural changes, either
of their ponderable or imponderable element, or of both, just as in the animate world
organic derangement is the invariable antecedent to functional disturbance. If caloric
be merely a property or quality of matter, it cannot possess that self-active and
causative power which a careful analysis of its history warrants us in assigning to it.
If it be a substantive entity, we can readily understand the remarkable constancy and
mathematical precision of its effects; and we can understand, furthermore, how its
presence or absence in certain quantities can produce those structural or molecular
alterations which manifest themselves externally in variations of form, specific gravity,
color, solubility, &. The estimation of the absolute amount of heat combined with
bodies in their different states of aggregation, is one of the most difficult problems in
physical science ;—and one of the most important, since upon its solution depends the
explanation of many unexplained and apparently inexplicable phenomena. However,
if we bring together the few reliable observations that have been made in this channel,
(especially those concerning the relation between the calorific condition and refractive
power of substances,) and the numerous collateral facts which are scattered throughout
the literature of physics, we will have material sufficient to begin already the work of
cautious and satisfactory generalization.

The following conclusions, as being more or less probable, seem to flow naturally
from the foregoing facts and arguments :—

1. That no invariable connection exists between the form and ponderable atomic
constitution of a body.

2. That form is immediately dependent upon peculiar axial proportions, which are
themselves the results of a certain molecular arrangement.

3. That the arrangement and disarrangement of atoms implies a motor agent;
while the definite and constant relation between changes in aggregation and variations
in form, implies the materiality of this agent and its continued presence, whether in
the same or varying quantities.

4, That this agent has periods of action and periods of rest.

5. That caloric is a positive material entity—an essential element in all bodies,
always present in different proportions.

6. That caloric is selfrepellant and endowed with great physical power.

7. That crystalline form is the visible representative of atomic volume.

8. That isomorphous bodies have sensibly the same atomic heat and the same
atomic volume.

9. That in elementary and compound isomorphous groups, the numbers indicating
atomic heat and volume are simply related.

134 RELATION OF ATOMIC HEAT TO CRYSTALLINE FORM.

10. That two or more atoms of one element may replace one of another, and retain
the same figure; and vice versa; hence, equal numbers of atoms are not essential to
isomorphism.

11. That similarity of constitution is- generally, though not always, accompanied
by sameness of combined heat.

12. That at certain temperatures, the elements may all be made to assume the
same form.

13. That variation in the atomic heat of a body is accompanied by variation in its
form.

14. That atomic heat is the cause of isomorphism and polymorphism,—consequently
of crystalline form in general.

Is caloric, through its affinity for, and active influence upon ponderable matter, the
primary physical cause of all crystallization ?

ART. XI.— Contributions towards a knowledge of the Marine InverTesrate Fauna,
of the coasts of Rhode Island and New Jersey.

By Josern Leipy, M. D.

The present communication consists of notices and descriptions of invertebrate
animals observed during a visit of two weeks, the last August, to Joseph P. Hazard,
Esq., on Point Judith, at the entrance of Naragansette Bay, Rhode Island; and of
other invertebrate animals collected by Samuel Ashmead, Hsq., or myself, in short
visits to Absecom Beach, in the vicinity of Atlantic City, New Jersey, and to Beesley’s
Point, at the mouth of Great Egg Harbor, New Jersey.

PORIFERA.

1. GRANTIA crLiTIA, Flemming. Sponge elliptical, with a single terminal orifice
surrounded with a crown of spiculs. Color yellowish white; length from two lines
to three-fourths of an inch. Point Judith ; attached to corallines, mytili, &c.

2. GRANTIA BOTRYOIDES, Flemming. Sponge branching irregularly ; branches ovate
or cylindroid, tubular, with a single terminal aperture. Structural spicule trident.
Point Judith ; with the preceding species.

POLYPI.

3. CLAVA MULTICORNIS, Johnston. (Pl. XI. figs. 33, 34.) Polypidom a very short,
thin tube of attachment. Polype clavate, with the dilated portion roseate, the re-
maining portions translucent whitish. Tentacule up to twenty. Ova attached in
clusters by means of a pedicle below the tentacule. Length of polypes up to two
lines. Point Judith ; in shaded pools between tides, attached to barnacles, the rocks, &c.

Although I found numerous individuals of this polype, I saw none greater than
the measurement above given; whereas, the european Clava multicornis is stated to
exceed half an inch in length. If this is a constant difference, most probably others
will be found on comparison sufficient to characterise the american Clava as a dis-
tinct species. In all the specimens examined I observed a polypidom in the form of
a small cup enclosing the basis of attachment, as seen in figures 33, 34.

4. HYDRACTINIA ECHINATA, Johnston. (PI. XI. fig. 35.) Polypidom crustaceous ;
brown, furnished with simple and compound spines. Polypes long clavate, trans-
lucent white ; with the head obtuse and furnished with an alternating circle of from
six to eighteen cylindrical tentacule, Ovigerous polypes smaller than the others, sur-

rounded with a many-lobed head, and having attached to the sides numerous ovigerous
capsules, of various sizes, containing from one to five ova. Length of polypes up to
one-fourth of an inch. Abundant at Point Judith and at Beesley’s Point, investing ©
the shells occupied by the hermit crabs.

EUCORYNE, Leidy. Polypidom, a rooted, branching, corneous tube with a soft
axis. Polypes terminating the branches of the polypidom, non-retractile, clavate,
furnished with a circle of long, cylindrical tentacule, and one or more circles of short
tentaculz: with globular tips.

5. Eucoryne ELEGANS, Leidy. (Pl. X. figs. 1-5.) Polypidom alternately branch-
ing, adhering by a coarse reticular root, and growing in profuse branches three or four
inches in length; trunk and branches shining black, and annulated at their origin;
branchlets yellow, and annulated at their origin and termination. Polypes up to
three-fourths of a line long, clavate, translucent white, with the dilated portion encircled
with two red bands. ‘Tentacule colorless, in two or three circles: first or basal
circle twelve in number, filiform, as long or longer than the body; second and third
circles of six in each, cylindrical and ending in globular extremities. Quite abundant
at Point Judith, adhering to corallines, and other fuci, mytili, &c., below low tide,

Gertner,* Van Beneden,t+ Hassal,{ and Johnston§ represent Coryne as haying the
tentacule terminating in globular extremities and irregularly distributed, while
Eudendrium is represented as possessing only a circle of filiform tentacule. Such
being the case, the polype, above described, would characterise a genus intermediate
to Coryne and Eudendrium. Gosse|| has, however, represented two polypes, which
he calls Coryne cerberus and Coryne stauridiai, each having a circle of simply filiform
tentacule, and a second of those with globular tips. As an examination of Hucoryne
elegans shows the two kinds of tentaculz to have a different arrangement in structure,
the two species just named either do not belong to the genus Coryne, or all the species
of the latter possess filiform tentaculz, and others with globular tips, which I suspect
actually to be the case, when the genus Hucoryne would cease to exist.

Eucoryne elegans is an exceedingly beautiful object, on account of the profuseness
of its developement, its graceful branching, and varied coloring. lI observed many
bunches four inches in length, but the main branches do not measure more than three
inches; the addition of length in the branches, being due to the successive origin of
the latter from stems of corallines, or other elevated objects of attachment.

The root of the polypidom is a coarse, tortuous, black fibre, reticulated upon the ob-
ject of attachment. Sometimes an ascidia is imprisoned by the net-work, but more
frequently it embraces the stems of corallines, or entangles masses of minute mytili.

The principle trunks of the polypidom are nearly straight, and they give off alternat-
ing branches, provided with from one to half a dozen branchlets. The trunks are
black, and are annulated at their commencement, for a short distance after giving off
the branches, and at their termination. The branches have the same color and
character of annulation as the parent trunks. The branchlets are ochre-yellow, and
annulated at their commencement and termination, or occasionally throughout ; and
frequently they give off secondary branchlets.

The polypes have the familiar form of the nine-pin, and are translucent white,
with two purplish red bands encircling the body at the base of the first two circles
of tentacule. The stomach of the animal is pink, and is visible through the trans-
lucent parietes of the body, between the red bands. ‘The head of the polypes is
conical, but in the expansion of the mouth is frequently observed to assume a cup
shape.

At the base of the polypes there is situated a radiating circle of twelve narrow,
cylindrical tentacule, about one line in length, and capable of retraction, inflection,
or complete reflection. The neck of the polypes is surrounded by two circles, each
of six, comparatively short, cylindrical tentacule, with large globular tips.

The long tentaculee of Hucoryne elegans are composed of an axis of large, nucleated
cells, surrounded with a delicate muscular sheath, and enveloped in a thin, ciliated
epithelium. Beneath these tentacule, extending their entire length, and enveloping
the tips, there is a stratum of nettling cells. The short tentacule have the same
structure as the others, except that the nettling cells are accumulated entirely at their
extremities, and thus give to these their characteristic globular form.

The nettling cells of Hucoryne vary in size, and present the same structure as the
principal ones of the fresh water Hydra. When the cells are entire they appear as
oval capsules containing at their fundus a hemispherical. mass of matter, which in
some instances has appeared to me to consist of a coiled thread, as represented in
figure 6, plate X. Above this mass or coil is a narrow oval capsule, within which is
a style, the point of which slightly projects from the summit of the nettling cell.
When the latter has emitted its thread, it appears partially collapsed, and from its
summit projects an irregular cone with four barb-like processes at the sides, and the
thread protruded from the apex, as represented in figures 5, 7.

As in other compound polypes the soft structure of the animals is continued as an
axis throughout the polypidom. This axis contains numerous nettling cells, as large
and as well developed as those of the tentacule. What can be their office in this
position ?

Hucoryne elegans produces medusa-like buds, in numbers of one to four, situated
just above the position of the first circle of tentacule. Very frequently a pair of these
buds become fully developed at the same time, and then appear larger than the parent.

138 LEIDY ON THE MARINE INVERTEBRATE FAUNA OF

They are attached by a narrow pedicle, are oval in form, and white in color, with
four longitudinal bands of purplish red. They have four short, conical tentaculz
and measure about half a line in length by one-third of a line in breadth.

In one instance, I found a small bunch of Hucoryne elegans, in which the polypes
had only two circles of tentaculz: the long cylindrical ones and a circle of the short
ones.

Since writing the foregoing, Mr. Ashmead has given to me several dried specimens
of Eucoryne elegans, from Great Egg Harbor. The bunches are not so profuse as
those of Point Judith, but one of them has a branch six inches in length.

6. LAOMEDEA GELATINOSA, Lamouroux. Small polypidoms attached to Mytilus
edulis, Laminaria saccharina, the rocks, &. Point Judith.

7. LAoMEDEA DicHoToMA, Lamouroux. (Pl. XI. fig. 36.) Polypidom very much
branched; branches alternate, annulated at their commencement, the larger ones
brown, the smaller ones light-yellow; branchlets annulated throughout, or at their
commencement and termination, from one to three times the length of the polype
cells ; the latter campanulate, with an even margin. Ovarian cells axillary, pedicled,
two or three times the length of the polype cells, urn-shaped, with the pedicles an-
nulated. Found abundantly, growing in profuse bunches, three inches in length,
attached to a submerged wreck on Absecom Beach. Specimens obtained by Mr.
Ashmead.

The nettling cells of the tentacule of Laomedea are numerous, and are arranged in
circles. They are elliptical in form, often curved, and minute; measuring from -0067
mm. to ‘0089 mm. long by :0022 mm. broad; and they contain a central style ex-
tending from one pole of the cell half through its length. These cells, of which two
are represented in figure 8, plate X, I saw at no time emitting threads.

8. CAMPANULARIA VOLUBILIS, Lamarck. Point Judith.

9. CAMPANULARIA DUMOSA, Flemming. Point Judith. I found small specimens of
what I suspect to be this and the preceding species, but had not the opportunity of
carefully examining their characters.

10. SertuLaria. Polypidoms, with opposite, tubular cells, the mouth divergent,
growing to about three-fourths of an inch in length, are very abundant at Point
Judith, attached to the roots of Fucus vesiculosus and I. nodosus, to the surface of
the rocks beneath these fuci, and to mytili, but I did not ascertain the species to
which they belong.

11. SerTULARIA cUPRESSINA,“ Lin. Found abundantly, thrown up on Absecom
‘Beach. Some of the bunches measure six inches in length.

12. AsTrANGIA AstRarormis, M. Ed. et Haime, An. des Sc. Nat. 1849, 181;
Astrangia Dane, Agassiz, (non M. Ed. et Haime), Proc. Amer. Assoc. 1850, 69.
Polypidom encrusting, flat or lobed, or pedicled and lobed. Polype cells short, ap-
proximate, fused together at their bases, cylindrical when free, subpolygonal when
crowded, externally slightly costate. Calices infundibular. Columella slightly de-
veloped. Partitions up to thirty-five in number, slightly exserted, narrow, with their
margin oblique and serrated and their sides denticulated. Polypes cylindrical, pro-
jecting up to half an inch in length, translucent white, brown, red, or green ; tentaculee
colorless, twenty-four in number, elongated conical, with rounded tips, situated in an
alternating circle ; mouth oval, situated at the summit of a conical proboscis. Coral
masses up to two inches in diameter. Point Judith. Found attached to rocks just
below low tide. /

The polypidom of Astrangia ustreformis was first described by Milne Edwards and
Haime, in the Annales des Sciences Naturelles for 1849. The living coral was first
discovered by Agassiz who dredged it from a depth of nine fathoms off Gay Head in
Martha’s Vineyard Sound.* At Point Judith I observed it in position attached to the
rocks a little distance below the lowest tide mark. It is especially interesting from
the fact that it is the only coral which has been discovered on the eastern shore of
the United States. Dead specimens have long been known, and the cabinet of our
Academy contains a number of them, among which is one attached to a fragment of
a Fulgur, from ihe coast of South Carolina.

Finding the living A. astreeformis afforded me an opportunity of examining its fili-
ferous capsules. These are especially abundant in the tentacule, and in certain white
cords of the interior of the body. The function of the cords just mentioned is yet
unknown. I frequently observed them extruded from wounds of the body of A.
astreformis. Wien detached they will spontaneously roll into a close coil; and are
composed of filiferous capsules arranged in a radiant manner around a central cellular
axis, enveloped in a delicate, actively vibrating ciliated epithelium.

The filiferous capsules of A. astreformis are of two principal varieties. The first
variety consists of oval, or ovoidal cells, about .05 mm. long by .0155 mm. broad,
containing a spirally wound thread, as represented in figures 11, 12, plate X. The
second variety consists of smaller cells; those of the tentacule measuring about .045
min. by .0067 mm., and those of the white cords .03 mm. by ‘0112 mm.; and they
contain besides a spirally wound thread, a style extending from one pole to about the
centre of the cells, as represented in figures 9, 10.

Both kinds of filiferous capsules, under certain circumstances not readily explained,
eject their contained threads with an astonishing degree of rapidity, and in so doing
the threads are absolutely turned inside out, as was first noticed by Agassiz,; and sub-

sequently by Gosse,* and remain attached to the emptied cells as long extended tubes,
From the smaller cells the style is also extruded, and then appears as a more expanded
portion of the thread, with which it is continuous at one end and with the capsule at
the other, as seen in figures 15, 16. An attentive examination of the extruded thread
exhibits a more complicated structure than would have been suspected, and as remarked
by Agassiz, who first detected the peculiar arrangement, its exact character is exceed-
ingly difficult to ascertain and requires the utmost power of the microscope to analyze.
In the case of the larger capsules a spiral arrangement is readily distinguishable, ex-
tending the entire length of the extruded thread. This arrangement in some instances
appeared to me to depend upon minute cilise, which project at right angles from the
thread, and apparently pursue a spiral course, as described by Agassiz, and as repre-
sented in figure 15; but in other instances, it appeared to me as if the thread during
its eversion from the capsule, assumed a spiral course within the portion preceding it,
and that the thread externally was encircled at regular intervals with non-vibrating
cilia, as represented in figure 14.

In the ease of the smaller capsules the extruded style appears as a tube much dilated
beyond its original calibre, narrowed at the extremities, and longer than the cell which
contained it, so that it appears to have been folded within itself. From the distal
extremity of the stylous tube projects the everted thread, which at times appeared
simple, but at other times appeared to possess a spiral arrangement, like the coarser
thread of the larger capsules. The tube derived from the style also presents a spiral
arrangement, apparently dependent upon long cilize pursuing a spiral course as repre-
sented in figure 16, or upon a twisting in the tube as represented in figure 15.

13. AcrrniA MARGINATA, Lesueur. Body when contracted, in the form of the segment
of a large sphere; when expanded, cylindrical; brown in color with longitudinal
bands of brighter brown. Tentacular disk deeply folded, translucent brown. Ten-
tacles very numerous, short, elongated conical, from one-sixth to half an inch in
leneth, brown tipped with white, sometimes with a median ring of white, and not
unfrequently the white altogether absent. Mouth nearly circular, surrounded with
an irregularly lobate, bright orange or reddish brown lip.

This species is abundant at Point Judith. In one position, beneath an overhanging
rock, a short distance from Mr. Hazard’s residence, I observed a group in the highest
state of development. Some of the individuals measured four inches across the ten-
tacular disk.

Var. ambrea. Attached to fuci I frequently observed small specimens of an Actinia,
two or three lines in diameter, and of a translucent ambreous appearance, which I
suspected to be the young of A. marginata.

* The Devonshire Coast.

Var. salmonea. I found two specimens of an anemone of the same form as that of
Actinia marginata, about an inch in diameter, and of a bright salmon color, which I
suppose to be only a variety of the latter species. It was attached to large mytili,
appeared to be more active than the undoubted A. marginata, and when irritated
ejected jets of water from large pores of the body, a phenomenon I did not observe in
the more ordinary variety. .

The filiferous capsules of Actinia marginata are numerous in the tentacule, but
especially so in the white cords of the interior of the body. (PI. X, figs. 17, 18).
They are elliptical in form, and measure about the .06 mm. in length by the .004
mm. in breadth; and they contain a spirally coiled thread and a style extending from
one pole about two-thirds through the centre. The ejected contents of the capsules
present two different forms. In the one case the style assumes the appearance of a
spindle-shaped tube, several times its original length, apparently having the extrud-
ed thread of the capsule coiled within it and having on its exterior long ciliary ap-
pendages, as represented in figure 21. In the other case the extruded style assumes
the appearance of a long narrow tube, apparently with the projected thread partly
coiled within it and partly everted from its distal extremity as represented in figures
19, 20.

14. Acrinia NEGLECTA, Leidy. Body when closed, obpyriform, or shortly cylin-
drical; when expanded, cylindrical, about an inch in length by one fourth of an inch
in breadth, smooth, translucent olive green. Mouth: elliptical, with the lip composed
of six greenish white lobes. Tentacles numerous, up to half an inch in length, brighter
olive green than the body. A single specimen was found in the mud of a sound, in

the vicinity of Atlantic City.
POLYZOA.

15. MemBranirora pitosa, Johnston. The stellate variety is very abundant at
Point Judith, encrusting the ruffled borders of Laminaria saccharina. It is also found
encrusting Chondrus crispus, the shells of Mytilus edulis, etc. Tn all the specimens I
observed, the cells possessed four lateral spines and a posterior spine, and this in no
case was developed to the dimensions which would give it the name of a bristle.

16. EscHARINA LINEATA, Leidy ; Flustra lineata, Lin. (PI. X. fig. 22.) Polypidom
crustaceous, circular. Polype cells oblong oval ; mouths large, with about ten inclined
spines on each side. Found by Mr. Ashmead, on pieces of anthracite coal from a
wreck, at Beesley’s Point.

17. Escrarra pepriostoma, Leidy ; Lepratia pediostoma, Hassal. (PI. X. fig. 23.)
Polype cells, six-sided oval, closely punctured; mouth subterminal, quadrate with
rounded angles, and slightly constricted at the sides. On shells. Beesley’s Point.
Obtained by Mr. Ashmead.

142 LEIDY ON THE MARINE INVERTEBRATA FAUNA OF

18. Escnarina VARIABILIS, Leidy. (Pl. XI. fig. 37.) Polypidom encrusting, spreading
in circles ; simple or lobate. Polype-cells exceedingly variable: square, oblong square,
tubular, oval, ovoid, or flask-formed; arranged alternately, semi-alternately, in ad-
vancing series, or opposite; more or less convex, or flat, or with a large spheroidal
dilatation in advance of the mouth; usually procumbent, occasionally semi-imbricated,
and rarely vertical ; when young glistening white, thin, and covered with perforated
mamillee; when old dull white, thick, and reticulated. Mouth terminally lateral or
median, usually to the left, circular, with an elevated border, emarginated inferiorly
or laterally, with or without a short tubercle below the emargination. Anal aperture
triangular, oblique, elevated, protected by a triangular corneous valve, usually situated
to the right of the mouth, occasionally to the left, more rarely beneath, sometimes
conjoined with tle mouth, and not unfrequently entirely absent. Polypes brownish
orange color. Found at Point Judith encrusting rocks and shells; obtained by Mr.
S. Ashmead at Great Ege Harbor, N. J., encrusting oyster shells, serpule, &c.

This species of Escharina may have been already described under half a dozen
names, but I found it no easy task to determine which they are. The Célleporide
are subject to great variety of form, and require much study before the true species
can be ascertained.

19. CrLnuLaria FASTIGIATA, Blumenb. Polypidom branching dichotomously.
Polype cells in alternating pairs, elongated conoidal, with a short spine supero-exter-
nally; mouth large, elliptical, with an entire margin. Found in small bunches attached
to fuci. Obtained by Mr. Ashmead, in Great Egg Harbor.

20. ALcYonIpIuM? PELLUCIDUM, Leidy. (Pl. X. fig. 24.) Polypidom translucent
white, attached by narrow fasciculated bases, which are extended in a procumbent
manner and then expand into wedge-shaped masses, upon the free, flat surfaces of
which the polypes are clustered. Polypes with bright orange colored tentacule.
Attached to rocks, mytili, sponges, &c., at Point Judith; abundant.

The masses of A. pellucidum from the white, fasciculated points of attachment to
the broad free surfaces are up to an inch in thickness. Although I preserved a
number of specimens in fresh sea-water for some days, I could not induce the polypes,
if they were such, to protrude from their cells, and I only had the opportunity of ex-
anining them in their retracted condition as represented in figure 24, plate X.

21. BowERBANKIA GRACILIS, Leidy. (Pl. XI. fig. 38.) Polypidom delicate, creeping,
branching, white. Cells cylindrical, erect, about one-third of a line in length, without
appendages at their orifice, the margin of which is retractile with the inhabitant of the
cell. Polype provided with eight ciliated arms. Intestine with a strong gizzard.
Point Judith.

THE COASTS OF RHODE ISLAND AND NEW JERSEY. 1435

This species differs from Bowerbankia densa in having a less number of tentacule
and in having no spines to the cells. From Fwrella our polype differs in possessing a
strong gizzard. The animal corresponds in its form very closely with the figure
given by Hassal in the seventh volume of the An. and Mag. of Nat. History for 1841,
Pl. vii. fig. 4.

22. PEDICELLINA AMERICANA, Leidy. (PI. X. fig.25.) Polypidom delicate, creeping,
white, with erect branches about one-third of a line in length, smooth and without
abrupt dilatations. Polype campanulate, white, with a wide, crenated border marked
with fine concentric lines. Tentaculze cylindrical, twelve or more in number. Found
attached to the roots of Laminaria saccharina, at Point Judith.

23. VALKERIA PUSTULOSA, Johnston. Polypidom growing in profuse, wide spreading
bunches up to two or more inches from the root of attachment. Stems flexuose ;
alternately branching at the flexures. Cells oval, arranged in semi-spiral clusters up
to a half a line in length and situated about the same distance apart. Found by Mr.
Samuel Ashmead, in Great Ege Harbor, N. J.

DENDROCGLA.

24. Monocenis Aciiis, Leidy. Body elongated elliptical, anteriorly and posteriorly
subacute, black or fuliginous. Hye brown. Length one line, breadth one-eighth of
a line. Found actively creeping on Mytilus edulis. Point Judith.

narrowed ; head auriculate. Hyes two, reniform, distant. Color above black, beneath
grey. Length one to two lines, by one-sixth to two-fifths of a line in breadth. A
small, quite active, and remarkably abundant species, found beneath stones, near
high tide mark. Point Judith.

26. Nemmrres socials, Leidy. Body long, linear, flattened, anteriorly subacute,
posteriorly obtuse or subacute; usually black above, and brownish ash'colored beneath,
oceasionally brownish ash colored with the anterior extremity tipped with black.
Head not constricted from the body. Eyes two to four pairs, arranged longitudinally
on each side. Length up to six inclies, by one-third of a line in breadth. Very
abundant, often in masses, about the roots of corallines between tides. Point Judith.

27. MECKELIA INGENS, Leidy. Body long, tape-like, narrowed posteriorly, cream
colored. Head obtusely angular, depressed ; lateral fissures deep. Generative aper-
ture a longitudinal fissure. Described from a specimen preserved in alcohol, and
measuring in its present condition, fifteen inches in length, eight lines in breadth and
three and a half lines in thickness. It was obtained by Mr. Chas. C. Ashmead,
from an oyster bed, at Beesley’s Point, New Jersey, and when alive measured more

than a yard in length.

breadth -072 mm. From the intestine of Nereis denticulata.

31. Leucopurys cLAVATA, Leidy, (Journ. Acad. Nat. Sc. ii. 50.) In. the visceral
cavity of Lwmbriculus tenws.

32. LEUCOPHRYS COCHLEARIFORMIS, Leidy. (Pl. XI. figs. 62,63.) Body curved cochle-
ariform. Length 135 to:18 mm. From the intestinal canal of Lambriculus tenuis.

I found four individuals of this remarkable species in a dozen of the Lumbriculus.
While within the intestine it appeared quiescent, but when set free it moved about
actively, by means of its long vibrating cilia, with the bowl-end forward.

ANNULATA.

NaraGANseta, Leidy. Body cylindrical, narrowed posteriorly ; no lateral pinne ;
segments numerous ; those anteriorly furnished with a few, simple, cylindrical, lateral
tentaculz ; anterior segments with four rows of simple sete in fascicles; succeeding
few segments with two rows of simple seta, and two rows of cochleariform podal
spines ; posterior segments with four rows of cochleariform spines. Upper lip distinct,

conical, eyes none.

33. NARAGANSETA CORAL, Leidy. (PI. XI. figs. 46—48.) Body black, brownish
or yellowish black, ninety segments in an individual, one inch anda quarter in length.
Hight comparatively short tentaculze on each side of the anterior six segments; three
to the first segment ; first two the shortest, the third the most robust; orange in color,
and except the most robust one, tipped with black. Anterior ten segments with four
rows of simple sete: in fasciculi of five; the succeeding four segments with two rows

of simple sete, and two rows of cochleariform podal spines; and the following seg-
ments with four rows of cochleariform podal spines in fasciculi of four to six. Point
Judith.

This curious worm lives in tubes within the dead portions of Astrangea astreformis.
It protrudes the anterior portion of its body with the orange colored antennz. The
latter are contractile, from one to four lines long, and with the exception of the third
or most robust one on each side, are tipped with black, as if to be subservient to the
impressions of light. Its setee are quite simple, as represented in figure 47, and are
about the fifth of a line in length. The podal spines consist of a long style ending in
a bowl, like that of a spoon, as represented in figure 48.

For the new genus, of which the worm just described is the type, I have adopted
the Indian name Narragansett, being that of the bay, on the shores of which the

animal was first discovered.

34. SABELLA OCULIFERA, Leidy. (Pl. XI. figs. 55—61.) Body demicylindroidal, pos-
teriorly narrowed, one hundred and thirty-eight setigerous segments to an individual
one and a half inches in length. Tentaculs: twenty-four in number, arranged in the
four-fifths of a circle, decreasing in length towards the extremities of the latter, re-
flected, supplied with about forty-eight secondary tentaculee, arranged in pairs; two
or three black eye spots on the back of the longer tentacule. Two rows of setz in
fascicles of about six, and two rows of podal hooks, in transverse series of ten. Setee
in the third to the ninth segment inclusive, in major part spade-shaped with a short
subulate point; of the following segments all like the latter. Podal hooks in
the first to the tenth segments inclusive, bird-like in form, associated with opposing
spade-like podal spines. Podal hooks of the following segments smaller than those
anteriorly. Worm living in tough tubes composed of mud, and found in a horizontal posi-
tion partially concealed beneath masses of Astrangia astreformis. Point Judith.

The plumose tentaculee with the dark eye specks on their back render this worm
a beautiful object. The surface of the tentacule is everywhere covered with vibrat-
ing cilia. By transmitted light the blood appears of a bright green color.

39. CLYMENE URCEOLATUS, Leidy. Body cylindrical, composed of segments of various
lengths, twenty-six in number including the head and caudal appendage. The anterior
eight segments the shortest; the seven preceding the last ten the longest; those in
advance of the third, and intervening to this and the sixth and the ninth, without
sete. Head obliquely truncated, concave, with a thin acute margin. Mouth inferior
triangular. Caudal appendage large, urceolate, with the margin entire. Color
reddish brown. Length five inches; breadth one and a half lines. Raked from the
mud in a sound about six feet deep, near Atlantic City, N. J.

146 LEIDY ON THE MARINE INVERTEBRATE FAUNA OF

36. CLYMENE ToRQUATUS, Leidy. Body cylindrical, with a membranaccous collar at
the fifth segment. Head abruptly truncated, concave, with a thin membranous border
emarginate below and on each side. Mouth inferior, at the sumimit of a double
ringed papilla. Length? (the posterior portion of the only specimen found, is either
wanting or the body terminates very abruptly.) The anterior fourteen segments
measure one inch and a half in length by one line in breadth. Found with the pre-
ceding species. |

37. PrectINARIA AURICOMA, Grube. (P. Belgica, Grube, Gould; P. Grenlandica,
Grube, Stimpson)? Body composed of nineteen segments including the head and
tail. Palese eight to sixteen in a fasciculus, according to age. Twenty-eight denticula-
tions to the frontal border. Length up toaninch anda half. PoimtJudith and Great

Ege Harbor.

38. 'TEREBELLA ORNATA, Leidy. (Pl. XI. figs. 44, 45.) Body with about one hun-
dred segments, of which forty-five are setigerous. The anterior teu ventral plates trans-
versely oblong square, those succeeding abruptly diminished in size. Tentaculee: nume-
rous ; branchiz in three pairs. Color brownish red. Length to four inches. Lives
in tubes of mud. Found at Point Judith, Atlantic City, and Beesley’s Point.

I found the young of this species at Point Judith. It had the appearance of that
of Terebella nebulosa, Mont., represented in fig. 24, pl. 3, of M. Edward’s Rech. Anat.
et Phys. etc. The single specimen obtained was three lines long. There were twelve
tentaculee, twenty-five eyes around the head, and twenty-eight segments to the body,
of which sixteen were setigerous.

39. SPIRORBIS SPIRILLUM, Lamarck. On Chondrus crispus. Point Judith.

Torquza, Leidy. Body cylindrical, narrowed at the extremities. Tentaculex
numerous, attached laterally to the head, capable of very great extension and con-
traction by the passage to and fro of blood corpuscles from the cavity of the body.
Hyes none. Sete in two rows, three to twelve in a fasciculus, extremities lanceolate.
Podal hooks in two rows, short, from twelve to forty in each transverse series, sup-
ported at the edge of a laminar process stiffened with fine, simple sete.

40. Torquea EximiA, Leidy. (PI. XI. figs. 51, 52.) Body soft, blood red. Ten-
taculee very numerous, capable of very great extension by the propulsion into them
of the bright red corpuscles, with which the cavity of the body is filled. Sets: anteriorly
in fasciculi of twelve, posteriorly from three to six. Podal hooks commencing at
the eighth segment, from twelve to forty in each series. Worm half an inch to an
inch in length, with from forty to sixty segments. Obtained from mud and sand
below low tide mark. Point Judith.

This worm is remarkable for its softness, its blood red color, its numerous extensi-

THE COASTS OF RHODE ISLAND AND NEW JERSEY. 147

ble tentaculee, and its numerous podal hooks. It is capable of slowly progressing, by
means of its tentacule. In the process, these are extended by having forced into
them the bright red corpuscles which fill the visceral cavity of the body, they then
attach themselves by their extremities to the surface upon which the animal is lying,
and by subsequent contraction the body is dragged after them.

41. CIRRHATULUS FRAGILIS, Leidy. (Pl. XI. figs. 8943.) Body cylindrical, narrowed
towards the extremities, reddish orange color, posteriorly greenish. Mouth inferior,
circular; upper lip conical. Eyes two. Cirri numerous, orange colored ; the first
pair, commencing at the second setigerous segment and the most robust. Sete in two
rows, simple, in fasciculi of three to five. Podal hooks in two rows, five to eight in
each fasciculus, sigmoid, bifid at the free extremity. Intestine cylindrical, constricted.
Ovaries on each side of the intestine, extending four-fifths the length of the body.
Worm three lines long, by one-fourth of a line broad, and composed of forty annula-
tions. - Found under stones, on the shores of Point Judith.

42. LUMBRICONEREIS SPLENDIDA, Blainville. Body cylindrical, copper-red and strongly
iridescent. Upper lip conical; mouth round, with a short proboscis armed with an
inferior pair of dental plates, as well as a complex dental apparatus above and within.
Hyes four. Caudal segment furnished witha pair of minute cirri. Lateral tubercles
with from six to ten sete in two fasciculi. Setse simple, distally curved and grooved
and ending in a subulate point. Length up to eighteen inches, with as many as 420
segments. Raked from oyster beds, in Great Eee Harbor, N. J., where it is abundant.
The animal corresponds closely with De Biainville’s description of a specimen, the
country of which, he remarks, he did not know.

43. Eunice SANGUINEA, Montagu. Body compressed, cylindroid, brownish red,
iridescent. Head with two oval dorsal lobes. The five antenne nearly equal. An
eye situated between the outer two antenne. Branchie blood red, commencing at the
sixteenth segment and continuing until within about forty segments of the posterior
extremity. Setigerous tubercles of the anterior sixteen segments containing two spines,
the remainder containing four. Seta in two fasciculi to each tubercle, simple and
compound, the latter consisting of a scalpel like blade received into a forked handle.

Length to five inches, with two hundred, and twenty segments. Found with the pre-
ceding.

44, GLYCERA AMERICANA, Leidy. (Pl. XI. figs. 49, 50.) Body cylindrical, brownish
red. Upper lip short, with hardly perceptible antennew. No branchial appendages
except three minute dorsal papille upon the pinne. The latter five-lobed, armed
with two spines and four fasciculi of simple and compound sete, thirty to forty in

number to each pinna. Simple setae linear, awned; compound seta composed of a

furcate handle and a long linear lanceolate blade. Length up to five inches, with a
breadth of one and a half lines, and about 240 setigerous segments, between each of
which is a secondary ring. Found at Point Judith, Atlantic City, and Great Kgg
Harbor. It is most like the Glycera capitata Oersted, but nevertheless is a different
species.

45. NEREIS DENTICULATA, Stimpson. Abundant at Point Judith, R. I, and on the
shores of Great Eee Harbor, N. J.

46. SIPHONOSTOMUM AFFINE, Leidy. Body cylindro-fusifurm, minutely papillated,
with four rows of fasciculi of sete ; those of the anterior three segments directed for-
ward ; those of the first segment one-third of an inch long; those of the third segment
one line long. Length to three inches, by two lines broad, with 80 segments. Ob-
tained by Mr. Ashmead, from Beesley’s Point, N. J.

47, LEPIDONOTE ARMADILLO, Leidy. (Aphrodita armadillo, Bosc., Lepidonote punctata,
Oersted, Stimpson; Polynoe squamata, M. Ed., Gould)? (Pl. XI. fig. 54.) Body of
twenty-four segments, with twelve pairs of elytrae completely covering the back.
Elytree fringed externally, spotted with variously colored papilla. Head round, with
two pair of eyes, three anterior tentacule and three lateral tentacule ; the middle of
the anterior and the first of the lateral tentaculse the longest, the former with two eye-
like black spots, the latter with none; all the others with a single black eye-like
dilatation or spot. Dorsal and anal cirri with black eye-like dilated spots. Length
an inch and a quarter, by three lines wide. Point Judith and Great Ege Harbor.
The Lepidonote squamata is described as having five tentaculee; in L. armadillo I in no
case could find less than nine, as represented by figure 54.

48. SigaAnion Maruirpm, Aud.et Edw. (PI. XI. fig. 53.) Body composed of over
200 segments, with over 150 pairs of elytra completely covering the back. Head

concealed by the bases of the second antenne. Sets of the dorsal pinne simple;
those of the ventral pinnz compound. Length over five inches, by two and a half
lines in breadth. Described from a specimen, with the posterior extremity lost, ob-
tained by Mr. Ashmead, at Beesley’s Point, N. J.

49. OPHELIA SIMPLEX, Leidy. Body fusiform, above convex, below flattened, an-
teriorly and posteriorly acute, reddish brown. Mouth inferior, round. Cirri com-
mencing at the third and ceasing about the twentieth segment. Setse in two lateral
approximated fasciculi, simple, linear. Length two-thirds of an inch, with about 30
setigerous segments. Taken from below low tide at Point Judith.

The genus Cepon was first described by Duvernoy, in the fifteenth volume of the
An. des Sciences Naturelles, but the individual he indicates as being the male of
Cepon typus is evidently the female of another species. Cepon distortus is not a very
abundant parasite, for after having accidentally found a specimen, in searching for
others, I destroyed fifty fidler crabs without obtaining a second. The parasite produces
no deformity, visible externally, of the animal it infests. The male was found in
the embrace of the female, as commonly observed in the isopodous crustacea.

In making out the foregoing list of crustacea, I have availed myself of the aid of
Dr. Bridges’ knowledge of this class of animals.

PLATE XII. Adult.

Form.—Rather smaller than Ara severa, (Linn.) Bill abruptly curved, culmen
flattened, bare space commencing at the nostril, including the eye and completely
inclosing the under mandible. Wing rather long, second and third quills longest and
nearly equal; tail graduated, containing twelve feathers.

Dimensions.—Total length (of skin) from tip of bill to end of tail about 15 inches,
wing 84, tail 82 inches.

Colors.—A large spot of yellow on the back of the neck, somewhat rectangular in
shape, and extending slightly on to the sides of the neck at its lower edge.

Head above, from the base of the bill to the crown, black, which is also the color
of the cheeks immediately next to the bare space. Occiput and all other parts of the
plumage, except the wings and tail, green, tinged with yellowish on the back and
wing coverts, and very slightly with bluish on the occiput. Primaries and secondaries
light blue; tertiaries same yellowish green as other plumage. Taii with the two cen-
tral feathers on their upper surface reddish chestnut or maroon for the greater part of
their length, yellowish green at base, and towards the end subterminally light blue
and narrowly tipped with yellow! Other feathers of the tail much the same, but
with the light blue predominating on their outer webs, and yellowish green on their
inner webs. Under surfaces of wings and tail pale silky yellow.

Hab.—South America; Bolivia.

Obs.—Peculiarly characterized by the large yellow patch on the neck behind, and
bearing no very near relationship to any species known to me. Three specimens, very
similar in plumage, are in the collection of the Academy, two of which have been
labelled in Europe as natives of Bolivia, the other is without label.

and nearly equal; quills broad, tail of twelve feathers, moderate, rather broad; tarsi
short, robust; small space around the eye, bare.

Dimensions.—Total length (of skin) from tip of bill to end of tail about 12 inches
wing 8, tail 42 inches.

Color.—Top of the head from the base of the bill, fine crimson, varying in extent
in different specimens; other plumage of the head above, green at the base of the
feathers, many of them having subterminal transverse bands of bluish cinerous, and
all narrowly tipped with black. Cheeks fine pale green, (with no yellow nor red.)

Entire plumage above and below, green; dark on the back and tinged with yellow
on the under parts ; every feather of the back, rump, neck, breast and abdomen nar-
rowly tipped or edged with black. First primary black, others green for the greater
part of their length, but bluish black at their tips. A large spot of fine crimson
occupying about the middle third of the first five or six secondaries, which are tipped
with fine blue. Tail above and below dark green at its base, terminal portion greenish
yellow, central feathers darkest, some of the outer feathers edged with reddish chest-
nut at their bases. Under tail coverts yellowish green, shafts of the feathers black.
Bill (in skin) pale yellowish.

Hab.—South America. Brazil?

Obs.—Several specimens of this bird are in the collection of the Academy, variously
labelled, but mostly “ Psittacus vernans?” and “ Amazona lilacina. Less.” It is not
the latter, and I do not know the former, if there is such a species.

This species considerably resembles C. awtwmnalis, (Linn.) but is invariably smaller
and has no yellow markings on the face. The bill is clear yellowish white, with no
tinge of brown or horn color, as in that species. The extent of the space on the
head occupied by both the crimson and bluish ash colors, varies much in different
specimens, and in one the latter color is nearly invisible.

under tail coverts, most obvious on the latter. Every feather of the entire plumage,
except the quills and tail narrowly tipped with black, nearly obsolete on the middle
of the breast and abdomen, but very conspicuous on the head, neck, back rump

coverts of the wings and tail, sides and flanks, and assuming the form of circular ter-
minal spots on the upper and under coverts of the tail.

Quills green on their outer webs, brownish black on their inner webs, tinged with
green and paler on their inner margins. Tail feathers green, the two central feathers
with a line of brownish black along their shafts and tipped with the same color, other
tail feathers also brownish black along the shafts and on their inner margins. Bill,
tarsi and toes light colored.

Hab.—Mexico, National Bridge.

Obs.—This handsome little parrot does not appear to be nearly related to any other,
but in general appearance bears a greater resemblance to some of the small Australian
species, than to any that are American. Two specimens are in the collection: one
brought by Mr. Pease from the vicinity of the National Bridge, and the other is in a
collection made by M. Bruzin, also from Mexico.

4. BRoTOGERIS AURIFRONS, nobis. Nov., 1855.

Form.—Similar to that of B. chrysoptera, (Linn.,) but larger. Bill rather com-
pressed, upper mandible lengthened; wing long, first and second quills longest and
very nearly equal; tail short, somewhat rounded; feathers narrow at the tips; tarsi
and toes robust.

Dimensions.—Total length (of skin) about 63 inches; wing 44; tail 2% inches.

Colors.—Narrow band in front (at the base of the upper mandible) and small spot
on the throat dark reddish orange. Inner of the greater coverts of the wings reddish
orange, fading into paler yellow at the ends, and forming a conspicuous spot on the
wing.

General color green, slightly tinged with brown on the back and with yellow on
the under parts of the body. Quills bluish-black, edged outwardly with green. Tail
green, with all the feathers yellowish on their inner edges, and on its under surface
silky greenish yellow. Under surface of the wings pale blue. Bill and feet pale dull
yellow.

Hab.—South America,

Obs.—This bird is related to B. chrysoptera, but is larger, and may be immediately
distinguished by its frontal band and spot on the throat of dark reddish orange.
Several specimens are in the collection of the Academy.

at its base.

Hab.-—Celebes.

Obs.—The only specimen of this bird in the collection, is one of the many valuable
contributions to our collections made by Mr. Edward Wilson, and is labelled as a
native of the island of Celebes. It is quite different from either P. platurus or P.
discurus, both of which are in the collection of the Academy, and is peculiarly cha-
racterized by its yellow breast and wide cervical collar of the same color.

ART. XIII.—Descriptions of some remains of fishes from the Carboniferous and
Devonian Formations of the United States.

By Josern Lerpy, M. D.

EDESTUS, Leidy.

Generic Characters.—Maxillary bones segmented ; segments beveled anteriorly and
excavated posteriorly for coadaption. Teeth in general form resembling those of
Charchavodon ; one coossified with each maxillary segment.

‘Epestus vorax, Leidy.

Proc. Acad. Nat. Sci., vii, 414. The subject of the present description is a fossil
fragment of the jaw of a remarkable and gigantic fish, which was presented to the
Academy by William S. Vaux, Esq., who obtained it from an itinerant showman. The
latter informed Mr. Vaux, that the specimen was discovered at Frozen Rock, Arkansas
river, twenty miles below Fort Gibson, in the Indian Territory.

The specimen is dense, heavy, and jet-black ; and when it was first received the
crevices about its surfaces were filled with carbonaceous matter. It was probably
derived from a coal bed; but the geological features of the locality from which it was
obtained I have been unable to learn.

The fragment of jaw is six inches in length ; and it measures three inches in depth
from the dental border. ‘The sides are symmetrical, and slope divergently from the
latter position towards the base, which is convex and moderately keeled in the median
line. At the dental border the jaw is about seven eighths of an inch in thickness, and
and at the thickest part cf its base measures one inch and four-fifths. Longitudinally
the base of the jaw is slightly concave and furrowed. The surface of the bone is
covered with fine vermicular, reticulating, broken ridges, assuming a striking resem-
blance to arabic writing.

The most remarkable peculiarity of the jaw is its segmented character; and of the
segments the fossil retains two very nearly perfect ones with portions of two others.
Each segment in outline forms an irregular pentahedron ; and each: possesses a single
coossified tooth, whose broad surfaces abruptly increase the acclivity of the sides of
the jaw.

From its general form the fossil might readily be taken for a portion of the lower
jaw, but from the fact that no vertebrated animal, neither living nor extinct, has jet
been discovered in which the dental branches of the inferior maxilla are segmented,
while several genera are known, as he Peele among living fishes, and the

160 LEIDY’S DESCRIPTIONS OF REMAINS OF FISHES FROM

Dendrodus of the Old Red Sandstone,* in which the superior maxille@ are segmented,
therefore it is a fair inference that the fossil in question is a portion of an upper jaw.

The maxillary segments of the fossil are beveled off on each side anteriorly to a
nearly acute edge, and are excavated posteriorly, so that the succeeding segments shall
fit into those in advance. Lach segment contributes to the sides of the jaw a band-
like surface curving from the dental border as far back as the position of the second
succeeding tooth, and then turning forward at a nearly right angle to the base of the
jaw, so that when the segments are conjoined they appear separated on each side
by > like grooves.

Near the middle of the anterior margin of the beveled portion of the segments, on
both sides there exists an oval foramen, the apparent continuation of a dental canal.

The teeth of the fossil are so closely set upon the jaw that the anterior basal angle
of those behind passes the contiguous angle of those in advance. Of the portions of
four teeth retained in the fossil, two are sufficiently well preserved to obtain some idea
of their form when perfect, as represented in the outlines of figure 1, plate 15. In general
form they appear to be like those of Charcharodon, but differ in a number of impor-
tant characters. They are compressed, conical, with coarsely dentated, trenchant
edges. Their two broad sides are symmetrical ; and they curve forward, so that in
the restored condition their anterior margin appears to be convex and the posterior
margin concave. Their base presents on each side a lobe-like expansion which ex-
tends upon the sides of the jaw, so that they look asif they were excavated and fitted
upon the dental border of the maxillary segments.

The width of the teeth at base is one inch and nine tenths, the thickness in the
same position four fifths of an inch, and the probable length is about two inches.
The denticles are slightly compressed conical, with trenchant edges, and are nearly
two lines long and over one line broad. In structure the teeth are solid and consist
of hard dentine. which is however of looser texture toward the centre; and they
are invested with smooth, shining enamel, about the one sixth of a line in thickness.

The teeth are firmly coossified with the maxillary segments, and indeed their
dentinal structure is absolutely continuous with, and undistinguishable by the naked
eye from the nearly equally dense ossific structure of the jaw.

A careless inspection of the fossil, at its posterior broken border would mislead one
to suppose the teeth were inserted by long fangs into the jaw, an appearance which
arises from the narrow portion of one fragment, continuous with its tooth, being
received into the excavation of the segment in advance.

THE CARBONIFEROUS AND DEVONIAN FORMATIONS. — 161

ORACANTHUS, Agassiz.

Generic Characters. Dorsal rays very large, compressed conical, with a large interior
cavity ; the external surface furnished with oblique and longitudinal rows of tubercles
or tuberculated ridges; without posterior rows of denticles.

ORACANTHUS veTUSTUS, Leidy.

Proc. Acad. Nat. Sci., vii. 414. This species is proposed upon an ichthyodorulite
or dorsal ray, from the collection of Mr. Timothy Conrad, now forming part of the
cabinet of the Academy. The specimen is from Missouri Territory, but the exact
locality from which it was obtained is unknown. It is dense, jet black, and heavy;
and it has its apex and base broken away. On one side towards the base it is crushed
inwardly, and in this position there is a portion of adherent iron gray limestone, with
a partially imbedded segment of a crinoidal stem, which Mr. Conrad views as an evi-
dence that the dorsal ray was derived from the carboniferous limestone. In several
places the ray is fissured ; but the parts appear to have retained their original relation-
ship, and the form of the ray is nearly perfect.

In its present condition the specimen is five inches long and two and two-thirds of
an inch wide at the base ; and its thickest portion is about eight lines. Its form is
flattened pyramidal and is curved a little backward and slightly also to one side. The
broad sides and posterior margin are thickly covered with mammillary tubercles but
the anterior margin is smooth. Between the tubercles the surface is slightly striated.
On the right side the tubercles are arranged in rows, irregularly longitudinal, and
irregularly oblique in the transverse direction. On the left side they are arranged
more regularly in longitudinal rows, and they evince a tendency to become confluent
in short transverse rows, which pursue an irregular waving course across the ray.
On the posterior margin, which is obtuse, there are several longitudinal rows. The
anterior margin of the ray is more obtuse than the posterior; and it narrows
towards the base. The thickness of the walls of this ichthyodorulite is not easy
to ascertain. The apex of the specimen exhibits a solid bony structure, but the base
appears to present thin lateral walls and a thick wall to the anterior border.

Plate 16, figs. 1, 2, 3.—Different views of the ichthyodorulite of Oracanthus vetustus.

PETALODUS, Owen.

Generic Characters. Teeth with fangs. Crown demi-compressed-pyramidal, broader
than long, with trenchant margins, surrounded by a basal cingulum composed of
narrow imbricating folds, and descending lower on one side than the other. Fang
large, undivided, laminar.

PETALODUS ALLEGHANIENSIS, Leidy.

Sicarius extinctus, Leidy, Proc. Acad. Nat. Sci., vii, 414.

This species of Petalodus is established upon the specimen of a tooth, which Mr.

162 LEIDY’S DESCRIPTIONS OF REMAINS OF FISHES FROM

Timothy Conrad borrowed from the cabinet of Charles A. Poulson, Esq., for mv in-
spection. It was presented to the latter gentleman by Townsend Ward, Esq., who, in
a note, observes, it was given to him “ by the engineer of the stationary engine at the
head of inclined plane number 3 of the old portage railroad,’ which crossed the
Alleghany Mountains from Hollidaysburg, in Blair County, Pennsylvania. Mr. Ward
further states, “it was obtained from a stratum about one foot thick, black, carboni-
ferous, and calcareous, which was exposed by the excavation for the buildings to
accommodate the stationary engine.” He then adds, “I obtained quite a number of
other fossils there, and from the same stratum near Freeport, above Pittsburg, and I
think on the Conemaugh, seventeen miles west of Johnston. I found the stratum
distinctly marked at these different localities, and have understood it is alsoto be seen
in Ohio, where it is as distinctly marked by its appearance and fossils. It is in the
bituminous coal series, and has a coal seam beneath it.”

The tooth is of an iron gray color, hard, well preserved, and perfect, except that the
basal angles of the crown and the end of the fang are broken away.

The crown has the form of one half of a broad, compressed cone. Its outer side
is smooth, and transversely convex, but slopes in a nearly even plane from the tren-
chant margins. The inner side is also smooth, and forms a vertical plane from the
latter position, and is transversely concave. The trenchant edges, except at the basal
angles, are nearly straight, and are minutely serrulated, or rather simply striated.

The basal cingulum surrounding the crown is bow-shaped on each of the broad
sides; and it is composed of about nine imbricating, parallel folds. Externally it
slopes inwardly beneath the crown; and internally it forms a thick convex ridge de-
scending much below its position externally.

The fang is an osseous plate, thick at the middle and towards the broken end, but
thinning towards the lateral borders, which are slightly bent, scroll-like, from within
outwardly. The inner surface is transversely concave ; thé outer one is convex, and
presents a wide groove following the course of the basal cingulum.

The mvasurements of the specimen are as follows: Breadth of the crown (not en-
tire) 14 lines; height, including the basal cingulum, internally 112 lines, externally
9 lines. Breadth of the fang 10% lines; length (not entire) internally 42 lines, ex-
ternally 7 lines.

HOLOPTYCHIUS, Agassiz.

Generic Characters.—Body broad, short, compressed. ‘Tail heterocercal, short.
Head flat; the bones rough, or irregularly granulated. A few large conical teeth
folded at the base, and numerous small conical, intermediate ones. Scales large,
more or less rounded, rhomboidal; the covered portion smooth ; the exposed surface

furnished with coarse, longitudinal, flexuose, anastomosing ridges or tubereles. Ven-
tral fins on each side, posterior to the middle; dorsal fin opposite the anal fin, which

is close to the caudal fin ; pectorals small.

HoLorrycaivus AMERICANUS, Leidy.

Holoptychius nobilissimus, Ag., Hall, Geol. of New York, pt. IV, 281, fig. 130.

By this name I propose to distinguish the remains of the genus which have been
discovered to the present time in Pennsylvania, although it may possibly include two
species. Remains of Holoptychius are stated to be quite abundant in certain localities
of the Old Red Sandstone Formation of Tioga county; but such as they are, consist-
ing of isolated scales, cranial bones, and teeth, they are so exceedingly friable and
the matrix so hard, or so soft and brittle that it is difficult to obtain specimens suf-
ficiently perfect to be characterized. Among numerous specimens, for the most part
consisting only of impressions left by the disintegration of the remains, presented to
the Academy, by Timothy Conrad, Hsq. and Charles E. Smith, Esq., there are a few
which I have ventured to describe, and which are represented in figures 9, 10 of plate
16, and figures 1-4 of plate 17.:

One of the specimens, represented in figure 9, plate 16, is a portion of a large scale,
with an impression of a portion of the remainder. It measures nearly 23 inches in
length, and apparently has been ovally rhomboidal in its perfect condition. The
covered portion of the scale constitutes nearly one half, and is smooth. The exposed
surface of the scales, as indicated by the impress of the matrix, was furnished with
coarse, longitudinal, flexuose, and somewhat ramifying ridges.

A smaller scale, represented in figure 10, plate 16, of which specimens are more
frequent than of the preceding, is 14 lines long and 12 lines broad, and is a rounded
square. A little more than half its surface has been covered by the scale in advance ;

‘and the exposed portion of the surface is covered with coarse longitudinal ridges.

This scale resembles an isolated specimen of one from Holoptychius nobilissimus, repre-
sented in figure 26, plate 31 a, of Agassiz’ Poissons Fossiles, but is not at all like those
represented in plate 23 of the same work.

The impression of a tooth, left in a portion of matrix by the destruction of the original,
from which a clay cast was taken, gives the form characteristic of the large teeth of
Holoptychius, as represented in figure 1, plate 17. The tooth has been ten lines long
and four lines in diameter at the base. It is conical, circular in transverse section, as
represented in figure 2, plate 17, and is folded two thirds of its length from the base.

A very imperfect fragment of a maxillary bone, consisting indeed of little more than
the thin internal surface adhering to a portion of matrix, represented in figure 3, plate.
17, exhibits at the anterior extremity the remains of a large tooth, partially consisting
only of its impression ; and further back at the margin of the bone it presents two

conical denticles about one line long.

canus, represented in figure 4, plate 17, appears to be one of the branchiostegal plates.

Its surface exhibits numerous short flexuose ridges, and tubercles, characteristic of the
cranial bones of the genus.

STENACANTHUS, Leidy.

Generic Characters. Dorsal spine long, narrow, straight, compressed conical, hollow,
longitudinally striated, furnished posteriorly with marginal rows of oblique denticles.

STENACANTHUS NiTIDUS, Leidy.

Proc. Acad. Nat. Sci., viii, 11. This genus and species are indicated by the specimen
of an ichthyodorulite, imbedded in a fragment of rock of the Old Red Sandstone For-
mation of Tioga County, Pennsylvania, and discovered by Charles E. Smith, Esq., who
presented it to the Academy of Natural Sciences. In the same fragment of rock with
the spine, there are also small portions of bones, and the impression of a tooth,
apparently of Holoptychius.

The specimen has its apex broken off, and also a portion of its left wall, exposing a
large interior cavity, filled with the sandstone matrix. _ It appears to have been per-
fectly straight in its length, and is long, narrow, compressed conical. The anterior
border is convex ; the sides are longitudinally striated or grooved; and the posterior
border is denticulated. There appears to be a pair of close rows of denticles, though
the specimen only exhibits one. The denticles are triangular, directed obliquely down-
ward and backward, and seven of them are equal to the space of half an inch.

About half an inch below the broken summit of the specimen, a zigzag fissure or
perhaps a suture crosses the spine, as represented in figure 7 of plate 16. From the
two lower angles of the fissure, two others proceed longitudinally downward to the
broken margin of the specimen. ‘These appear like real sutures, though they are most
probably mere cracks, the result of fracture.

The length of the ichthyodorulite in its present condition is two inches and two
thirds, and its width at base about half an inch.

outline.

APEDODUS, Leidy.

Generic Characters. Opercular bones, thick, covered with hard and finely granulated
enamel. Teeth large, compressed conical, with trenchant margins and a grooved base.

THE CARBONIFEROUS AND DEVONIAN FORMATIONS. 165

APEDODUS pPRISCUS, Leidy.

This species is founded upon specimens of a tooth and a fragment of bone, from the
Old Red Sandstone Formation of Columbia County, Pennsylvania, which were sent
for my inspection by Prof. Baird, from the cabinet of the Smithsonian Institution.

The tooth is seven lines in length, compressed conical, with trenchant edges, and is
slightly curved. The two broad sides are very nearly symmetrical; the transverse
section being elliptical and rather abruptly narrowed towards the acute poles. The
trenchant margins are entire, and the surfaces are smooth, except at their lower half,
where the tooth is grooved as in Lepidosteus and Holoptychius. 'The base of the tooth
is four lines and a quarter in breadth, and two lines and a half in thickness. The
tooth appears to be solid, and is invested with thin enamel.

The fragment of bone mentioned, which I have considered as having belonged to
the same fish as the tooth, for no other reason than that they were found in association,
appears to be a portion of an opercular, or perhaps a sub-opercular bone. It is thick
and dense, and on the exposed surface is invested with thin, shining, and minutely
eranulated enamel. Viewing the specimen as an opercular bone, it has been over two
inches in length, and about an inch anda half at its widest part. Its anterior margin
is thin, and beveled off for the fourth of an inch for adaptation to the preopercular
bone. ‘The posterior margin is convex; the lower extremity is a little prolonged ;
and the upper broken margin of the specimen reaches one line in thickness.

ART. XIV.—Deseription of some remains of extinct Mammalia.

By Josepu Leipy, M. D.

CamELops Kansanus, Leidy. Proc. Acad. Nat. Sci., vii, 172.

This genus and species are established upon a fragment of the anterior extremity of
an upper jaw of an animal of the camel family, discovered by Mr. Henry Pratten, of
New Harmony, Indiana, in the gravel drift of Kansas Territory. :

The specimen consists of portions of the left maxillary and intermaxillary bones, —
the latter of which contains the fang of a transformed incisor or functional canine.
tooth, as in the lama.

The intermaxillary bone is of very much more robust proportions than in the lama
or camel. Its upper part and outer surface form the segment of a slightly flattened.
cylinder, and from the nasal side to the outer side of the aperture of its alveolus it
is an inch in breadth, while in the lama in the same position it measures only the
third of an inch, and in the camel about half an inch. The inclination of its nasal
border approaches more the horizon than in the lama or camel, apparently indicating
the animal to have possessed a lower and perhaps a longer face than in either of the
latter genera. The gingeval border is rugged as in its congeners, and it presents two
irregular pits, apparently the alveoli of incisive germs.

The fang of the functional canine contained in the intermaxillary bone is laterally
compressed conical, and is an inch and a half in length. From the orifice of its
alveolus it is strongly curved upward and backward, nearly on a line parallel with
the curved palatal margin of the bone. The crown of the tooth was directed
downward and outward; and at the base it is ovate in section, with the narrow end
posteriorly ; and it measures six lines and three fourths wide, and three lines and
three fourths transversely. A small portion of remaining enamel indicates this to
have been thin and smooth.

The small remaining fragment of the maxillary bone attached in the fossil exhibits
at its broken margin the portion of an alveolus, situated an inch and three fourths
behind the tooth contained in the intermaxillary bone. It has been about four lines
in transverse diameter, apparently had a direction curving downward, forward, and
outward from its bottom, and probably accommodated a true canine tooth, although
the position is unusually far back, a necessary condition however in the Oumelops,
from the distance to which the fang of the functional canine tooth extended backward.

The margin of the hiatus between the alveoli indicated is subacute and concave ;
and it measures one and three fourths of an inch in length. It is divided about the

middle of its course by the maxillo-intermaxillary suture, which descends at the side
of the jaw parallel with the nasal border, and on the palate curves inward and
advanees as far as the position of the posterior third of the orifice of the intermax-
illary alveolus.

Canis primavus, Leidy. Proc. Acad. Nat. Sci., vii, 200.

This name is proposed for an extinct species of wolf supposed to be indicated by a
fragment of a skuil, discovered by Mr. Francis A. Lincke, in association with remains
of Megalonyx Jeffersonii, Bison americanus, Cervus virginianus, Equus americanus, and
Tapirus Hays, in the banks of the Ohio River, near the mouth of Pigeon Creek, a
short distance below Evansville, Indiana. The specimen, which with others were
kindly borrowed for my inspection by Dr. J. G. Norwood, of New Harmony, consists
of the left upper maxillary bone containing the back five molar teeth, which are
nearly entire except the penultimate. tooth.

The fragment on comparison with the corresponding portion of the skull of the common
wolf of HKurope, and its american congeners, differs only in being larger and in present-
ing slight variations in the teeth, not however. greater than those found among
different varieties, or perhaps even individuals of recent wolves.

Certain naturalists may regard the fossil as indicative of a variety only of the
Canis lupus, and of the correctness of such a view, an attempt will not be made here
to decide. Naturalists have not yet systematized that knowledge through which they
practically estimate the value of characters determining a species. What may be
viewed as distinct subgenera by one will be considered as only distinct species by
another, and a third may view both as varieties or races. In the use of these words,
or rather in the attempt to define them, we go too far when we associate them with
the nature of the origin of the beings in question. We know nothing whatever in
relation to the origin of living beings, and even we cannot positively deny that life
connected with some form was not co-eternal with time, space, and matter, and that
all living beings have not successively and divergingly ascended from the lowest
types.

To return to a consideration of the fossil: the maxilla has the same form as the
corresponding bone of recent wolves with which I have had the opportunity of cor-
paring it. The infra orbital foramen, is vertically oval, directed forward, and is on a
line vertical to the interval of the third and fourth molar teeth.

The crown of the penultimate molar tooth is rather less concave posteriorly than
in any recent specimens under inspection; and its antero-posterior diameter internally
is greater in relation with the same diameter externally; or in other words the tcoth

43

168 LEIDY’S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA.

internally is less narrowed than in recent wolves. It is also broader in the antero-
posterior diameter when compared with its transverse diameter; and its basal ridge
externally is a little more abrupt and is slightly crenated at the border. |

The second and third molar teeth have their basal ridge internally a little better
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 corres-
ponding part in recent wolves, are given in the following table.

Ursus AMPLIDENS, Leidy. Proc. Acad. Nat. Sci., vi, 303.

This species is founded upon a fragment of lower jaw and an upper molar tooth,
which were discovered in association with remains of Megalonyx, Mylodon, Ereptodon,
Equus americanus, Cervus virginianus fossilis, and Mastodon, ina ravine in the neigh-
borhood of Natchez, Mississippi.

The fragment of the jaw is of the left side; and it contains the last molar tooth,
It has about the same size as the corresponding portion of the jaw of the common
black bear (Ursus americanus), or of that of the grizzly bear (Ursus ferow) at an age
when the permanent teeth have all protruded but are not yet worn by attrition. Its
form also does not vary from what itis in the latter animals, except that it is more
convex externally.

The last molar tooth is intermediate in size to that of the black and the grizzly
bear, but the form of the crown is more like that of the former than that of the latter.

The specimen of an upper molar is the penultimate one of the left side. It has
very nearly the same form as in the grizzly bear, except that the small cone in front
of the outer pair of principal cones is almost as well developed as that behind them.

LEIDY’S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA. 169

The slight variations indicated in the fossils might be considered as insufficient to
characterise them as having belonged to a distinct species from the grizzly bear, but
when we reflect upon the equally slight variations which exist in the homologous
parts to the fossils in certain recent species of the genus, and recollect that the fossils
in question were found in association with remains of the Megalonyx, &c., im a country
never known to have been inhabited by the grizzly bear, we cannot help inclining to
the belief that they belonged to a species distinct from the recent ones.

URSUS AMERICANUS FOSSILIS.

Remains of the common black bear ( Ursus americanus) have on several occasions
been discovered in association with those of extinct animals. Dr. Harlan* mentions
an inferior maxilla, which was found in Big-bone Cave, Tennessee, in association with
remains of the Megalonyx. The specimen, which is preserved in the collection of the
Academy, contains none of the teeth, and it is unchanged from the original texture,
except that it has lost a small portion of its gelatin. It is not improbable that the
specimen may be of much later date than the Megalonyx remains with which it was
found.

Another specimen preserved in the cabinet of the Academy, consists of the left
half of the lower jaw containing the canine and anterior two molar teeth of a species
of bear, discovered in a ravine in the vicinity of Natchez, Mississippi, in association
with remains of Megalonyx, Mylodon, Ursus amplidens, Equus americanus, Bison lati-
frons, Cervus, &e. The specimen corresponds closely in its anatomical characters
with its homologue of the common black bear. The bone is exceedingly friable, and
is enveloped in a thick layer of compact peroxide of iron, in the same manner as the
specimen upon which was established the Felis atrox,; and which was found in the
same locality.

the peccary tribe, Platygonus compressus, Protocherus prismaticus, &c., in the lead
region of the vicinity of Galena, Illinois.

Besides several phalanges, the fossil specimens alluded to consist of several fragments
of jaws and teeth. }

A small fragment of the upper jaw (figure 17, plate 17) of the left side contains
the fourth and fifth molars, which have the same form as the corresponding teeth of
Procyon lotor, but are about one sixth larger.

A specimen of a right upper canine tooth has the same size as in the recent raccoon,
but is rather less compressed towards the subacute borders of the crown. (Figure 24,
plate 17.) ia

A small fragment of the right side of a lower jaw, (fig. 19,) rather larger than the
corresponding portion of the same bone in the recent raccoon, contains the canine and
the fourth molar tooth. The former has the same form, as in the recent raccoon, and is
only a little larger. The latter‘tooth is not only larger than its representative in the
recent raccoon ; but it has the inner posterior ridge of the crown continuous with the
principal cusp and not terminating in a small cusp, and the tubercle at the outer
posterior part of the base of the principal cusp is hardly developed in comparison with
its condition in the recent raccoon. (Figs..19, 20, 21.)

An apparent, isolated, inferior, third molar tooth (figs. 22, 23) of the left side has
more nearly the form of the fourth one than of its homologue in the recent raccoon, and.
it is also relatively larger in comparison with its associated succeeding tooth than:in the
latter species. ‘The principal cusp and that developed from its base postero-externally
are more distinctly separated than in the corresponding points of the fourth molar of the
recent raccoon. The anterior heel also is less developed and that posteriorly is less
exeavated than in the succeeding tooth of the recent raccoon, with which it is com-
pared in preference to the corresponding one of the latter species. The size and form
of the two fangs of the fossil tooth correspond with the same characters of the two
alveoli for the third molar in the fragment of a lower jaw above indicated. In con-
clusion it must be admitted that had this last, described tooth been found alone it
would without hesitation have been viewed as a third inferior molar of Procyon lotor.

LEIDY’S DESCRIPTION OF REMAINS OF EXTINCT MAMMALIA. 171

Awomopon Snypert, Le Conte. Am. Journ. of Science and Arts, 2d ser. v, 106.

In association with the remains of Procyon priscus, just described, there was found
a curious tooth, which Dr. Le Conte has supposed to be the left superior canine of a
large ‘insectivorous animal. It is quite peculiar in form; and its affinities I am at
present unable to determine.

The tooth is compressed to a remarkable degree, and on the inner side for the greater
part of its length is depressed, so that a transverse section except near the apex of
the crown would be reniform. The crown is curved conical, and is most convex ex-
ternally. Posteriorly its outer and inner surfaces are separated by a feeble ridge; and
internally about half way towards the base it is furnished with an anterior and a
posterior tubercle, of which the former is lower than the other.

The fang at the broken border of the specimen is nearly half an inch broad and is
less than two lines thick. In consequence of the deyeeysion of its inner wall, the
pulp cavity has a curved linear form, thus c

In its perfect condition the tooth has apparently been in theneighborhood of an inch
and a half long, and the base of the crown measures five lines broad and one and
three quarter lines thick.

ART. XV.—On the Sandstone Fossils of Connecticut River.

By JAmes Deane, M. D.

Prior to the year 1839, the indications of organic life, co-existing with the sandstone
deposition of Connecticut River, were exclusively confined to a few genera of hetero-
cercal fishes. This rock was formerly supposed to be so destitute of animal remains,
that when in this year I opened a new chapter of its organic history, my discoveries
were treated with incredulity and neglect. But, after the investigations of twenty
years that have resulted, itis known to be exceedingly rich in the imperishable
materials of geological history. Very few indeed have any conception of the
marvellous perfection of these fossil inscriptions, or of the multitudes of once living
creatures whose existence they commemorate. During the vast sandstone deposition,
it is presumed that animals whose instincts and organizations attracted them to littoral
margins, were as numerous as their living representatives. The immense groups of
birds embraced countless individuals who have inscribed upon the shores whereon
they congregated their unmistakeable and instructive history. Most of the finest im-
pressions have never been described, and the rich discoveries of late years, render a
thorough revision of these fossils indispensable to a clear comprehension of the sublime
truths they teach.

Other inferior creatures existed in astonishing profusion during the sandstone
period, and like the birds, have left the imprints of their feet vivid as upon the day
they were made. The presumption is that they embraced as a class, animals no
higher in the scale of organization than vertebrated reptiles. They were quadrupedal,
and were grouped into several orders; Saurians, Batrachians and Chelonians. Of the
saurian and batrachian orders I am acquainted with twenty species at least, and shall
present herewith a notice of ten of that number. In one essential feature all these
impressions concur, and that is, in the difference in magnitude between the anterior
and posterior feet, the latter being about four times greater than the former. This
distinctive character, and the diminutive size of the animals they indicate, appear to
distinguish them into species, having their affinities in existing salamandrian or tailed
Batrachians.

The indications of Tortoises prove them to have been very numerous, but it is
nearly impossible to detect specific differences. Their movements over soft mud re-
sulted in ploughing up a trace or furrow by the solid armor of their bodies. In some

instances the swinging movements of their feet are well preserved, and in rare cases
the pedal imprints are also visible. |

174 DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER.

Descending in the scale of organization, this rock has retained the foot-print of in-
sects and crustacea with surprizing fidelity. Nothing in the strange history of the
sandstone fossils, is more astonishing than the unrivalled perfection of the vestiges of
these frail creatures.

In this brief memoir I shall endeavor to portray some of these interesting hiero-
elyphics of extinct existences. Fig. c, pl. 18,is an unimpeachable footprint of a bird, no
other animal could impress it. Its analogies are unmistakeable. It is a left foot, the
inner toe has two, the middle three, and outer four phalanges, exclusive of the nail,
which is in exact correspondence with the feet of existing trydactylous birds. The
triple-headed, or distal extremity of the tarso-metatarsal bone, is also unequivocally
impressed. Naturalists may, if they prefer it, explain the origin of these impressions
upon the hypothetical existence of such monsters as biped reptiles, but by the unerring
laws of comparison, I have never hesitated for a moment to ascribe these footprints
to birds. In this opinion I am sustained by a distinguished comparative anatomist,
who, in relation to fig. c, remarks, “that some naturalists would call it reptilian, be-
cause, according to their idea of cosgomony, birds did not exist in the new red sand-
stone period, and there are some very distinguished naturalists who maintain this
doctrine, but I call it the footprint of a bird, cosmogony or no cosmogony.”

Fig. @ is quadrupedal, and is Batrachian. Each foot has four toes radiating forward,
and the anterior foot is considerably more advanced than is usual. This is a very
beautiful specimen of these delicate footprints.

Fig. d has four toes, two diverging outward and two inward. They are thick and
somewhat massive, and blunt at their extremity. Both the anterior and posterior
feet are analogous as to form.

Fig. e is an elegant and interesting example of the quadrupedal impressions, and
the most diminutive ever seen. It is very perfect, yet it is difficult to comprehend
the place to which the amimal who made them should be assigned. All the other
quadrupeds move by alternate steps, but in this example both right and left feet fall
simultaneously. There is no impression of a fore foot, but this is a common defect
in delicate quadrupedal impressions, the impression of the fore foot not always being
retained. It may be that the imprint of the anterior foot is obliterated by that of the
posterior foot. The dragging of the foot from one step to another is distinctly pre-
served. There were probably four toes. The surface upon which the creature moved
is smooth as if polished, and no other would retain the imprints with such extraordinary
fidelity.

Fig. b is probably Saurian. It is exceedingly perfect. It is a hind foot with five
heavy toes, if the appendage upon the left be considered asa toe. It has a Chirotherian
aspect, but as it is a solitary example, and is separated from the fore foot, its true
relations cannot be exactly determined. The fine preservation of its massive heel and
toes renders it a very beautiful example of foot prints.

DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER. 175

Fig. a, diagram A, pl. 20, isan undescribed species of quadrupedal imprints. The foot-
prints are defective, being impressed when the mud was too soft to retain forms, but
this condition was favorable to receive the trail of the animal’s tail, which is exquisitely
preserved. This is a raré feature.

Fig. 6, diagram A, pl. 20, is likewise new and undescribed, and is remarkable for the
disparity of the anterior and posterior feet. The fore feet are very perfect, four thick
but pointed toes radiate outward and somewhat backward. The posterior feet are
comprised of four long, slender toes, lying nearly parallel, and the feet are divergent.
Right and left feet widely separated.

The foregoing species of quadrupedal imprints have never been figured or described.
Those which follow are copied from drawings made by myself and published in the
Journal of the American Academy of Arts and Sciences a few years since. They are
inserted here for comparison, although a simple outline of a foot can convey no
adequate idea of its organization.

Fig. a, diagram B, pl. 20, is remarkable for its peculiar symmetry. Four thick,
tapering toes radiate forward, and in the hind foot the impression of the heel is pro-
longed backward to a considerable distance, and is broad and flattened. The fore foot -
is planted a little in advance and a little outward of the hind foot.

Fig. }, diagram B, pl. 20. The hind foot consists of three thick, pointed toes, widely
spread, and a short toe pointing inward. The heel is projected backward, and termi-
nates in a rounded extremity. The anterior foot is not conformable to the posterior.
Four toes, two pointing forward and outward, and two outward and backward. In
birds the foot points inward without exception ; in quadrupedal impressions it diverges
outward in every instance I have ever seen except this. The hind foot inclines
slightly inward. Both examples upon diagram B are exquisitely beautiful and perfect.

Fig. a, diagram C, pl. 20, is a series of very delicate foot-prints. Toes four, long and
slender, and drag from one step to another. Impression of anterior feet not retained.

Fig. 6, diagram C, pl. 20,is probably Saurian. Toes have a chirotherian look, thick
and massive. Feet divergent. The fore foot planted near the hind, sometimes partially
obliterated by it. Stride very great. Fig. d, diagram C, is probably analogous, and
both, with the exception of the appendage upon the side opposite the thumb, have a
striking resemblance to fig. 0, pl. 18.

The remaining fig. c, diagram C, pl. 20, is probably Batrachian ; toes four, feet
divergent, impressions of anterior feet not retained.

The impressions upon pl. 19 are of recent discovery, and the obscurity of their
origin is in proportion to their beauty and extraordinary preservation. Nothing of
the kind has hitherto been described or even discovered.

Fig. a of this plate is remarkable for the geometrical symmetry and perfection of the
dotted impressions, which are arranged in ON each a reproduction of the other.

~

176 DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER.

I think in the present state of science it is impossible to explain the origin of this elegant
fossil. If the accuminated bodies that constitute the various lines of impressions be
not due to the deciduous fronds of plants, they must be taken for the dermoid pro-
tuberances of some animal. ‘There is not the slightest evidence of a compressed stem
of a coniferous or other plant, which should certainly be the case in so perfect a
specimen; and moreover, upon the superior or superincumbent stratum, the imprint
is reversed ; it is a cast, and this, it appears to me, is conclusive evidence against a
vegetable origin. Ihave drawn this beautiful fossil with excessive care, for it is the
most difficult puzzle I have ever encountered, and I must leave it to others more com-
petent than myself 10 determine its origin. The reader who will take the trouble to
analyze the various line of impressions, wili find a corresponding number in each repe-
tition. Thus in the unbroken row running obliquely upward from left to right, there
are invariably fourteen of the protuberant points, and in each other line, when re-
peated, is consistent, both as to number and arrangement of the geometrical lines of
elevations.

The remaining figures upon this plate are probably foot-prints of a class of creatures
not higher in the scale of organization than the articalated division of animals, and a
few observations perhaps may assist in deciding upon their origin. I rely more upon
the fidelity of the drawing than upon any descriptions to convey exact ideas. :

Fig. 7, pl. 19, is the simplest form of these linear imprints. It is a single set of
straight, slender, parallel feet, planted in regular succession.

Fig. f. The set is also single, feet slightly divergent, and terminate in an enlarge-
ment or depression, caused apparently by the momentum by whicli the creature moved.

Fig. c. The two rows upon the left are identical with those of fig. f but there is
also an additional row of impressions upon the right, the terminations of which are
not excavated.

In fig. 6 the impressions are identical with fig. c¢, except that the order is reversed.

In fig. h two sets of feet are exquisitely preserved. The irregular or odd number
of feet may perhaps be explained upon the hypotheis that the creature was moving
upon the bottom of the water, and by floating used a part only of its organs of
locomotion. This conjecture is sustained by the fact that the rows of impressions
sometimes appear and disappear abruptly upon the surface, and are both preceded and
succeeded by delicate prolonged lines, caused by dragging of the feet.

Fig. g displays two rows of linear feet, and are very fine indeed. The entire length
of the original impressions is fifteen inches.

Fig. & shows a row of parallel linear feet, and corresponding rows of lateral bulbous
impressions.

Fig. d also shows the central or parallel rows, and two corresponding lateral rows
of curved feet.

Fig. ¢ exhibits the trail of the body, with lateral feet.

These extraordinary fossils occur upon surfaces as smooth as polished marble; no
other would receive, much less retain such delicate impressions with such fidelity.
To explain their obscure meaning I have sought the assistance of several gentlemen
distinguished for their scientific attainments, and it gives me pleasure to subjoin their
opinions to these meagre descriptions of my own.

Prof. Leidy considers the impressions &;, d, 7, /, c, and 6, to be the tracks of insects
and crustacea; g and e those of worms; and a, from its remarkable uniformity, to be
rather a vegetable than an animal impression.

Prof. Gray is of opinion that fig. a represents leaf scars of some plant like a tree
fern.

Prof. Wyman is of opinion that fig. a is a vegetable impression, and that the other
impressions upon this plate are due to articulate animals, insects or Crustaceans.

Prof. W. B. Rogers is of a similar opinion as regards fig. a, yet he remarks that this
is but conjecture, and that we are without any guide as to MD might be esteemed
a probable interpretation of this mysterious inscription.

Prof. Dana can refer fig. @ to nothing but a plant, the prominence being the traces
of leaves, probably coniferous; still it is not like any known coniferous plant, ancient
or modern. Upon the remaining figures of pl. 19 he offers the following valuable re-
marks: “The delicate linear tracks must be made by an articulate animal. They
can hardly have been made by annelids (excepting e and g of which there is doubt),
and may have been made by Crustaceans or insects, perhaps water insects. I should
incline to say Crustaceans. Among the tribe of this class they may have been either
Entomostracans, Isopods, Macrourans, or small species of Anomourans. Isopods have
too small legs and pointed claws to make so large a track as 4, and they would not
make the two distinct series of this figure, or a track with three impressions as in ¢,
The legs spread from the longitudinal axis, and do not point forward asin 7. Still
it is possible that d and & might have been made by an Isopod, the bent form of the
track in this case being due to the fact that three joints of the leg, pressed on the mud
in the progress of the animal. There is a small tribe of Crustaceans near the Isopods,
which I have called Anisopods, in which the two anterior feet often have large claws,
and are projected forward in front of the head, and such an animal might make marks
with these claws like J, but I should think they would be likely to be less regularly,
or even continuous lines.”

“The Entomostracans may have been tracking the mud ; but so small species of that
group have usually very thin or slender feet, commonly more or less foliaceous for
swimming.”

“T should therefore be inclined to refer the triple and quadruple track to small
Anomourans. The two more central tracks, where there are four, being made by the

178 DEANE ON THE SANDSTONE FOSSILS OF CONNECTICUT RIVER.

anterior claws; and the one where there are three to the claw of one side, for it is
very common for one claw to be larger than the other, and sometimes the difference
of size is exceedingly great.”

“T cannot say that g and e are Crustaceans, as some large Isopods have legs that
would make as strong impressions. But in Isopods the three anterior of the seven
pairs of legs are directed obliquely forward, and the four posterior pairs obliquely
backward, so that there would hardly be with such animals the exact uniformity of
direction these tracks present.”

In bringing this paper to a conclusion, I must here express my acknowledgements
to the gentlemen who have so politely responded to my request for information. I
am also under peculiar obligations to Roswell Field, Ksq., who is the discoverer of all
the original specimens of the two plates and those of the diagram A, and who kindly
loaned the specimen. The estate of Mr. Field is situated at Turner’s Falls, and by
his sagacity and activity he has been very successful in developing the history of these
sandstone fossils. He has made many very splendid discoveries. ‘The fossils that

constitute the originals of the plates and diagrams are exclusively from Turner's Falls.

ART. XVI.—Pianta KANEANE GRENLANDICA. Hnumeration of Plants collected by
Dr. B. K. Kane, U.SN., in his first and second expeditions to the Polar Regions, with

descriptions and remarks.
By Eras Duranp.

I have brought together in the following enumeration all the plants collected by Dr-
Kane at the stations of his two voyages, the whole belonging to the western coast of
Greenland, and nearly to the same geographical zone.

These stations were, for the first voyage, (1850 and 1851,) Sukkertoppen, Holstein-
' borg, Egedesminde, Disko, Upernavik, and Wolstenholm, between the 64th and 76th
north parallels; and for the second, Fiske Fiord, Sukkertoppen, N. Proven, Uper-
navik and the different stations of Smith’s Sound as far as 81° N. latitude.

The first collection was in pretty good order, but the second had suffered much from
the peculiar hardships attending the last period of this eventful expedition, in which
Dr. Kane’s fortitude and devotion to science were so signally manifested. Surrounded
with difficulties of every sort, and threatened by the impending danger of starvation
and death, amid the drifts, disruptions and other impediments of a hyperborean cli-
mate, he did not hesitate sacrificing the useful articles of comfort and self-preservation,
to make room in his luggage boxes for as many of his scientific collections as he could
pack in them.

Thus was the best portion of his botanical specimens preserved to science, after suf-
fering much, as it may be imagined, from the inclemency of the weather, and the
hardships of a long and perilous voyage back to the United States. But for the zeal
and self-denial of his comrades, and especially of his surgeon, Dr. I. I. Hayes, his co-
laborer in the scientific field, Dr. Kane is pleased to acknowledge that he could never
have undertaken their transportation.

Under these circumstances I have experienced great difficulty in determining seve-
ral specimens,—difficulty arising not only from their damaged state, but also from
their occasional incompleteness, some being just blooming, others in a fruiting condi-
tion, others again wanting some of the essential characters. To these disadvantages
I must add the want, in several instances, of books of reference, and of authentic spe-
cimens for comparison. .

When I attempted the task of determining these collections, I relied much, I con-
fess, on the assistance of a learned and more experienced friend, Professor Asa Gray ;
but, owing to the pressure of his occupations, I have not been able to secure his val-
uable services to the extent of my anticipations. I am, however, greatly indebted to
him for hints and remarks that have been very useful to me. I am under peculiar

180 PLANTA KANEANZ GRONLANDICA.

obligations to Professor Torrey for the determination of the Gramineae, and hisassist-
ance in some of the most perplexing genera; and also to my friend Thomas P. James,
Hsq., for the entire enumeration of mosses, Hepaticee and Lichens. Iam most happy
to take this opportunity to render to these three gentlemen my sincere acknowledg-
ments for their great kindness.

Laying aside the consideration of the lost packages, Dr. Kane’s collections are yet
among the richest and most interesting ever brought by Arctic and Polar explorers.
They not only afford a considerable accession to our previous knowledge of the vegeta-
tion of Northern Greenland, but they develop facts of some importance in a physico-
geographical point of view :—

First—By exhibiting, throughout the range of coasts between the Arctic and Polar
circles, no perceptible change in the number and identity of the species therein col-
lected ; thus establishing, as far at least as Greenland is concerned, that the third or
Polar zone of Sir John Richardson* might as well begin at the 67th as at the 73d N.
latitude.

Secondly.—By the reappearance, beyond the limits of Smith’s Sound, of Hesperis
Pallasti and Vesicaria arctica, in a perfect fruiting state—two plants belonging rather
to the milder regions of the Arctic zone, and which have never been found yet, I be-
lieve, in the higher intervening points. Both these plants belonged to a scanty collec-
tion of eight or ten species, made late in the season, on the newly discovered lands of
Washington and Humboldt, on the very verge of that mysterious Polar sea which Dr.
Kane’s expedition had the good fortune to espy and see free of ice as far as the eye
could reach. Such a fact indeed, although limited to two species, seems to indicate
peculiar isothermal influences, depending either on warm currents, greater depth of
water, or actual depression of our globe at its poles.

Another remarkable feature of Dr. Kane’s collections is, that, dividing into two
equal parts the whole extent of coasts visited by him, and each section presenting
about the same number of stations at which herborizations were made, the northern
section, from Upernavik to Washington Land, has yielded more dicotyledonous plants
than the southern, from Fiske Fiord to 73°; and Smith’s Sound alone, only three de-
grees in length, has proved nearly as rich. (See Table No. 1.) ;

These unexpected results show that the Polar zone cannot properly be compared
with the Alpine regions of the more temperate climates. The uninterrupted action —
of light and heat, during the whole period between the rising and setting of the sun
which marks the day or summer season of the poles,—a purer and damper atmosphere,
aided, perhaps, by a greater accumulation of electric fluid, &c.—must necessarily and

more promptly (in the lowest levels) actuate and perfect the vegetation, not only of

“See Appendix to Searching Expedition, London, 1851, p, 319 and following,

PLANTA KANEANA GRGENLANDIC. 181

plants inured to those climates, but also of those the seeds of which have been trans-
ported hither from milder regions by currents, migration of birds, or other causes.
Unlike the snow-capped and barren summits of the Alpine regions, at all times des-
titute of verdure, itis probable that vegetation is permitted toextend to the very pole
itself, wherever it meets with proper soil, favorable solar exposure, and protection from
the blasts of winds. |

The southern extremity of Greenland, from Cape Farewell to Sukkertoppen, has
been well explored, and found to possess nearly the same climate as Labrador, with
an almost identical vegetation. E. Meyer, in his Plante Labradorice, (1830,) enume-
rates 224 phzenogamous species, the greater part of which are indigenous both to Lab-
rador and to Greenland. Professor Giesecke, who resided several years in Greenland,
for the express purpose of studying its Natural History, published in Brewster's Ed-
inburgh Encyclopedia (1832) an enumeration of 171 phzenogamous species, with a
long list of Cryptogams, amounting to no less than 231 species, all indigenous to that
island. From the two above works, and from all the other sources to which I have
had access,—De Candolle, Torrey and Gray, Hooker, Brown, Richardson, Hornemann,
Steudel,—for Cyperaceze and Graminez, &c., I have compiled the following Table No.
2, which presents an amount of 264 phzenogamous species, belonging to 109 genera
and 36 families.

This apparent richness of the Greenland flora is, however, confined to the extreme
southern point of the island; for, from Sukkertoppen to a few degrees higher, it is
found to have lost already eight or ten families; and from Upernavik, 73°, to the out-
let of Smith’s Sound, it is reduced to twenty families, by the entire disappearance of
Violacee, Oxalidacee, Holoragee, Umbelliferee, Cornacee, Lentibulacee, Primulacee,
Gentianacee, Boraginacee, Labiate, Plumbaginacee, Plantaginacee, Betulacee, Coni-
Sere, Orchidacee, and Melanthacee.

Notwithstanding this prodigious decrease, the column headed North Greenland from
73°, in Sir John Richardson’s Statistical Tables, will be found, by the accession of 27
other species from Dr. Kane’s collections, now to be raised—from 49 phzenogamous
species allotted to that region by the eminent English botanist—to 76; which is a
gain of fifty per cent. .

The following species are to be added to Richardson’s column of North Greenland
from 73° :—

Ranunculus Sabinii? | Dryas octopetala. Hieracium vulgatum. 1 Salix.
Hesperis Pallasii. Alchemilla vulgaris. Vaccinium uliginosum 2 Eriophorum.
Vesicaria arctica. Potentilla frigida. Pyrola chlorantha. Agrostis canina.
3 Draba. Sedum rhodiola. Diapensia Lapponica. Festuca ovina,
Arenaria arctica. 2 Saxifraga. 2 Pedicularis. 27
Cerastium, N. Sp. ? Gnaphalium sylvaticum. | Empetrum nigrum.

Only two new species, Pedicularis Kauei and Bryum lucidum, have been found in
the whole collections.

ENUMERATION.—DICOTYLEDONOUS PLANTS.
RANUNCULACE.

1. RANUNCULUS AQUATILIS, var. arcticus. Foliis omnibus emersis, consimilibus,
profunde tripartitis ; partitionibus cuneatis, ad marginem dilatatis, crenatis ; flore albo ;
sepalis ovalibus, concavis, petala fere zequantibus.

This form, of which I have only two specimens, has a great affinity with De Can-
dolle’s R. aquatilis, var. hederaceus, R. hederaceus, Lam., not of Linn. (vide Fl. Frane.
vol. 4, p.894.) The stems are fistulous repent, with small fascicles of radical fibres at
each node below the scape. No capillaceo-multifid leaves; they are all suborbicular
tripartite, on long vaginant petioles, 3—4 at the base of each peduncle ; leaflets cu-
neate, with dilated crenate margins, each crenature having a blunt mucro. Scape
thick, naked, one-flowered, 3—3% inches high. Flower white, middle size, with five
oval and concave sepals about the length of the petals.

spicuous divergent veins. Cauline leaves sessile, palmate. Flowers rather large, deep
yellow; petals oval-rounded, about twice the length of the calyx which, as well as
the peduncle, is covered with a thick, brown toment. Root perpendicular, with nu-
merous white and thick fibres, indicating a plant Heeply, rooted in mossy beds,

PAPAVERACE A.

5. PAPAVER NUDICAULE, Linn., spec. pl. p. 725. Fl. Dan. T. 41. Pursh’s FI., p. 364,
&c. The most hardy plant of the polar regions, resisting the first frosts and remaining
the last in flower. The leaves and especially the seeds, which are very oleaginous,
are a great resort in scorbutic affections and agreeable to the taste. Dr. Kane.

This plant was found at all the stations of the two voyages, and extends probably
to the farthest limits of vegetation.

subterranean stems, simple or dichotomous, with short internodes, each provided with
a pair of small scarious leaves; the external stems are furnished with a rosula of
ovate and softly lanuginous leaves, and each stem has a solitary erect peduncle, with
2-3 pairs of remote and appressed hoary leaves, and a single erect flower, nodding in
the fruiting stage. Stems very numerous.

This species varies very much in its forms: I have stems scarcely one inch high,
densely cespitose, with, leaves all imbricated in four rows and flowers almost sessile;
‘others with numerous branches thiekly set and spreading on the ground, leaves im-
bricated in the inferior part and opposite towards the top; others again with long
sterile branches and leaves all opposite and remote. I have also the form WS. Esch-
scholtzit of Sternb., with silvery gray foliage, which cannot be separated from this
species. rom the large and beautiful purple flowers, apparently monopetalous, which
are peculiar to this species, I have no doubt it is the plant mistaken for a gentian by
Dr. Kane, in the narrative of his first expedition.

Pedicularis Kanei is easily distinguished from P. arctica by the delicacy of its pin-
nules, which are all remote on a rachis scarcely dilated ; by its bracts, perhaps more
lanuginous, but almost entire; by its rose colored flowers, its edentate helmet, and
the thin texture of its corolla and calyx. The middle lobe of the inferior lip and
stigma are not emarginate as in P. arctica, and the germ is of a more globose form.
It is, moreover, a larger plant, with many more stems and a more fleshy root.

P. lanata, Willd. A larger plant than the two preceding, with erect, leafy and lanu-
ginous stems. Leaves linear-lanceolate, pinnatifid with the rachis remarkably dilated ;
the lower pinnules very small, the other larger and dentate. Spike leafy and crowded;
calyx half the length of the corolla, which is much smaller than in the two preceding
species, and of a yellow color. An old stem in fruit, seven inches high and quite
glabrous, with mucronate pods at least half an inch long, has the leaves bipinnate.
Other imperfect specimens from N. Proven are not half the size of those from Smith’s
Sound, with very small flowers,seem to belong to the same species—perhaps a varity ?

This variety is probably the same as that collected by Vahl on the eastern coast of
Greenland, and described by Prof. Hornemann as var. decumbens. The stems are
quite prostrate, as almost all the forms of serpyllwm ; the leaves are of a pale green
color, with pellucid dots, ciliate at base,and with veins remarkably prominent and
symmetrical. Flowers capitate among the upper leaves, which, as well as the calyces,
are tinged with bright purple. Calycinal teeth and lobes of the corolla ciliate.

I have been somewhat perplexed with specimens collected by Dr. Kane at the
Smith’s Sound Stations. They are comparatively smaller in all their parts, and have
dried yellow, probably from some atmospheric causes, or the more advanced season.
Some of these specimens, with leaves quite lanceolate and acute at both ends, and
small ovoid catkins, resemble the figure of S. Lapponum, in Fl. Dan. T. 1050, except
that their leaves are petiolate. They are, however, subject to all the same variations
in leaves and catkins as S. arctica of the lower latitudes, and Dr. Torrey says they
agree well with the Hookerian specimens of his herbarium.

ART. XVIL—A Commentary on the Synopsis Fungorum in America Boreali media
degentium, by L. D. de Schweinitz.

Bythe Rev. M. J. Berxerry, M. A., F.L.S., and the Rev. M. A. Curtis, F. A. A. A. S.

With a view to place the Mycology of the United States on a firm and stable
foundation, a careful examination of most of the species which still exist in the
Herbarium of Schweinitz has been instituted by the authors of the present Memoir.
Free access has been also had to the numerous authentic specimens in the Herbarium
of Sir Wm. Hooker, and Prof. Torrey has kindly presented us the collection given
him by Schweinitz. About a fourth of the species have passed under review, and as
the examination of the remainder must necessarily be a work of time, we think it
best to publish the present by way of instalment. When the whole has been
reviewed, we hope to be in a position to give a complete Mycology of the United
States, for which we have immense materials. As Schweinitz did not possess types
of the greater part of the Kuropean species, it was impossible that he should not have
made many mistakes in the determination of species; but though we have been
compelled to differ frequently from him in his diagnoses, the species which he has
published as new, with few exceptions, still hold their place in science, and present
numberless points of interest as regards structure and affinity. He was, however,
very far from exhausting the treasures of the American forests. We have in our
possession a host of new species, equal in interest to those which first gave so high a
character to American Fungi; and a review of these authentic specimens has, in only
a very few instances, compelled us to change our nomenclature. There will be no
longer delay in the publication of the remainder of our commentary, than unavoidable

circumstances may necessitate.

** When our paper upon the Exotic Fungi of the Schweinitzian Herbarium (see
Journ. Acad. 11. p. 277) was written, we had not ascertained from whom the Surinam
species were procured, there being no recognition of the collector upon the tickets.
We have since learned that the collection was made by Dr. Hering, now a distin-
guished Homoeopathic Physician of Philadelphia. Dr. Schweinitz had evidently
intended to commemorate this gentleman’s services in Natural History by naming
for him the genus since published by Berkeley under the name of Hyporyssus. (See
_Kxot. Fung. No. 15.) Herrera is now devoted by Agardh to a genus of Algz.

206 BERKELEY AND CURTIS'S COMMENTARY

100. AGaricus siccus, Schwein.! This resembles very closely Marasmiws hama-
tocephalus, Mont., but the upper half of the stem has a transparent appearance, and
there is a cottony tuft at the base. The appearance of the stem is very much like
that of A. coherens. Schweinitz’ description of it does not accord very well with the
specimens.

147. A. peTALorES, Bull. Certainly not the plant of Bulliard, though similar in
habit. It is Punus angustatus, Berk. in Hook. Lond. Journ. vi. 518.

152. A. stypticus, Bull.= Panus stupticus, Fr.

154. A. Ateipus, Fr.= <A. atroceeruleus, Fr.

159. “A. AppLicAtuS, Batsch. epiqge@us.” Probably a distinct species.

162. A. NigER, Schweim.! A larger species than A. applicatus, very dark and
with somewhat of the habit of Xerotus.

229. A, DEPLUENS, Batsch.

230. A. VIOLACEO-FULVUS, Schwein. Apparently A. pimsitus, Fr. Certainly not a
Creprdotus.

267. FAVOLUS ALVEOLARIUS, Fr.= Polyporus Boucheanus, Fr.

268. F. aBNorMIs, Schwein., marked “ Favus membranaceus” in the Herbarium,
has the hymenium of Gl@oporus, of which it may be a resupinate form.

269. LENTINUS SCHWEINITZII, Fr.

278. CANTHARELLUS AURANTIACUS, Fr. In the fragments we possess of what
Schweinitz assigned to this species, the gills or folds are far broader than in any
Kuropean specimens. We consider the name, therefore, as very doubtful. The
species has not yet occurred in 8. Carolina.

281. C. LUTESCENS, Fr.
282. C. CINEREUS, Fr.
284. C. oporAtus, Schwein. != Craterellus odoratus, Fr.
286. C. CINNABARINUS, Schwein. != Hygrophorus cumnabarinus, Fr.
_ 287. C. rLoccosus, Schwein.! C. Canadensis, KI. is apparently the same species.

289. C. crispus, Fr. This seems to be a common species in the Northern States,
but has not yet been detected in the Southern.

290. C. INCARNATUS, Schwein.! More properly a Merulius, and evidently allied
to M. tremellosus. Authentic specimens exist in the Herbarium of Sir Wm. Hooker.

Not an uncommon species in the Carolinas.

of Taxodium. It appears to be a common production in the United States.

298. C. curpuLaris, Fr. Our specimens of this are imperfect.

299. C. rascicuLatus, Schwein.! This is properly a Cyphella. There is a species
in our collections to which we gave the name of Cyphella fasciculata before we knew
that the plant of Schweinitz belonged to that genus, exactly agreeing in habit, but of
a paler and more washy tint, perhaps from being exposed to the weather.

— 300. C. oLtvacrus, Schwein.! There is but a single specimen of this in the
Herbarium, and it is arranged there under Meruliuws. At the time of our examination
we referred this to Puwxillus panwoides, Fr., but it may perhaps be P. Curtis, Berk.

not P. rufescens, but a state of his own P. connatus, of which he considered P. cinna-

momeus, P., a synonym.

329. P. Scuweinitzu, Fr. P. tabule@formis, Berk., is confounded with this. .

330. P. connatus, Schwein.! A fine authentic specimen remains in the collection
at Kew, and others exactly agreeing with it were sent by the late Mr. Lea from
Ohio. These, however, run so gradually into P. perennis, that there is some doubt
about the stability of the species, notwithstanding the enormous difference in the size
of the pores. Fries informs us that this is P. parvulus, Klotsch. P. connatus, Fr.
and Weinman is a totally different species.

331. P. Rapicatus, Schwein. Specimens of this very distinct species, with the
pileus varying from 13 inch to 5 inches across, and the stem from 12 to 9 inches long
and % to 12 inch thick, were sent from Ohio by Mr. Lea. Allied certainly, as
Schweinitz himself hints, to such species as P. ciliatus, Fr., though immensely larger.

not black as far as the pores, but only half way up. Such specimens occur in great
beauty in Ohio.

334. P. Lucipus, Fr.=P. Curtsu, Berk.

341. P. GRAVEOLENS, Schwein! This is the same thing with P. conglobatus, Berk.,
and a most extraordinary and magnificent species. It is, however, by no means
“durissimus,” though it forms a compact close mass, but the texture is as soft ‘and
velvety as that of P. fomentarius. This circumstance, and the very different smell of
the Schweinitzian and Ohio specimens, led to the notion that the latter was a distinct
species. The odor of the former is described as oppressive and nauseous, whereas the
specimens of Mr. Lea, though clearly identical, had a most attractive smell like that
of strawberries. This grateful odor is found also at times in the Southern specimens,
which we have heard compared to that of the flowers of Calycanthus, and that of the
Water Beetle.

343. P. Lagyrintuicus, Schwein! A very fine species, remarkable for its coarse,
tow-like texture.

344, P. spumgus, Fr. According to Fries (Nov. Symb. p. 39) this is P. fusco-albus.
The specimens in Herb. Schwein. are nearly destroyed.

345, P. BETULINUS, Fr.
346. P. cutongus, Fr.
347. P. pesrructor, Fr. The specimens are marked with a note of interrogation,

and we think them somewhat doubtful, though clearly belonging to the same section.
The stbstance is yellowish, and it may possibly belong to some undescribed species.

348. P. Lactgus, Fr. The specimens are too much worm eaten for allowing any
satisfactory decision, but they do not seem to belong to P. lacteus.

349. P. stypticus, Fr. Nearly destroyed and unfit for comparison with our au-

thentic speciniens.

360. P. NIGROPURPURASCENS, Schwein! This highly curious species belongs to the

ON SCHWEINITZ’S SYNOPSIS FUNGORUM. 209

genus Gleoporus, Mont. It seems identical with what Dr. Montagne has sent from the
south of France under the name of P. dichrous, P.; but specimens from Fries under
that name are more like P. adustus, so that there is some doubt about the species. It
should be observed that Fries considers this to be merely a state of P. tsabellinus,
Schwein., which we did not find in the Herbarium.

361. P. AMorpHuS, Fr.

362. P. apustus, Fr.

363. P. crispus, Fr.

364. P. utmArius, Fr.=P. scruposus, Fr.

366. P. popuLinuS, Fr. The Schweinitzian specimens were found on an apple tree, |
and are undoubtedly distinct. They may be characterized as follows :

TRAMETES MALICOLA, Berk. et Curt., imbricatus, ligneus; pileis dimidiatis posticé
decurrentibus subvillosis subzonatis, ligneo-umbrinis ; porismediis dissepimentis crassis
subtomentosis.

It differs clearly in the far larger pores, darker pileus, &c.

370. P. Pitora, Schwein.! This is apparently the same thing with P. hypococcinus
Berk., the differences arising rather from age, or from the greater perfection of the
Ohio specimens. No mention of bright showy colors is made by Schweinitz, except

2

in the qualified phrase “ intus subrutilans.”

374. P. vELUTINUS, Fr.=P. hirsutus, Fr.

375. P. NIGROMARGINATUS, Schwein.! Merely a state of P. hirsutus.

378. P. srereoipes, Fr. We are not acquainted with the species of Fries, but the
Schweinitzian specimens are the same with P. pergameneus, Fr.!=P. Menandianus,
Mont.

379, P. rapratus, Fr. var. curpineus. Certainly the same with P. seruposus, Fr.!

380. P. PALLESCENS, Fr. Of this we have only fragments. One with a hirsute

pileus is P. hirsutus, another may be the true plant.

381. P. apreinus, Fr. The same with 378. The true species of this name occurs
in the Herbarium with the ticket marked “ P. poroides—pinicola, L. v. 8.” and is very
common in the U. States.

382. P. vircingus, Schwein.! The specimens are totally different from the original
species, being densely villous. They are the same with a slight variety of P. Sulli-
vant, Mont., which occurs in S. Carolina. The species, however, which we have
from more than one source is very distinct.

210 BERKELEY AND CURTIS'S COMMENTARY

383. P. concuireR, Schwein.! The true species exists in Hook. Herb., and is most
beautiful and distinct, differing in character and habit from every thing else. Very
fine specimens were gathered by Mr. Lea in Ohio. The Schweinitzian specimens be-
fore us seem to be a discolored state of P. virgineus, of which however we have seen
no authentic specimens.

385. P. pEcIPIENS, Schwein.! (marked P. affinis.) This has larger pores than P.
versicolor, and is of a yellowish tinge, but still is not a very well marked species.

386. P. pARVULUS, Schwein. There is no species of this name in the Herbarium,
but the plant mentioned above under 381 (“ P. poroides—pinicola”) is probably the
one intended under the present number.

387. P. SCUTELLATUS, Schwein.! A very curious species, extremely well described,
but not closely allied to any published species except P. compressus, Berk., a Swan
River Fungus.

388. P. sSANGUINEUS, Fr.
389. P. CINNABARINUS, Fr.

393. P. BEnzomnus, Fr. Authentic specimens from Fries are totally different from
this, which has the colors of such species as P. 7adiatus, scruposus, &c. It is indeed
very closely allied to the former, from which it differs in its larger size and less yellow
substance. It can therefore retain the name of P. fusco-gilvus, originally given to it
by Schweinitz, and by which it is ticketed in the Herbarium. But our specimens are
not sufficiently good to allow of our drawing up a specific character, and possibly it
may be identical with P. cuticularis, Fr.

395. P. NIDULANS, Fr.

396. P. curicuLaris, Fr. Not the true plant of Fries. It is clearly a form of his
P. conchatus.

397. P. RuTILANS, Fr.=P. scruposus, Fr. Schweinitz himself says, “an carpi-
neus,” and it is certainly the same with No. 379.

398. P. gitvus, Schwein.! (Hook. Herb.) Sir W. J. Hooker's specimens are P.
scruposus, Fr., but Fries must have received something very different under this name.

399. P. mareinatus, Fr.

401. P. annosus, Fr. Certainly not the plant of Fries, but more like P. igniarwus,
which perhaps it may be, though our notes and recollection of the specimen are
imperfect. .

402. P. pryaprus, Fr. Not the European species, from which it differs evidently

ON SCHWEINITZ’S SYNOPSIS FUNGORUM. 211

in its rhubarb-colored substance and minute pores; and in the latter character it
differs also from P. dryophilus, Berk. The Schweinitzian plant is, as we believe,
only a form of P. scruposus. Specimens exactly similar were gathered by Mr. Lea

in Ohio.

409. P. ropatus, Schwein. This is one of the specimens missing from the Herba-
rium. It must be very different from the Friesian homonym.

410. P. Pint Canapensis, Schwein.! Certainly the same with P. hypococcinus,
Berk. See above, No. 570.

411. P. sponetosus, Fr. The plant of Fries is a resupinate form of P. nidulans,
such as occurs in Scotland, which this certainly is not. The pores are too large to
allow of its being a state of P. igniarius, but our materials are scarcely sufficient for
arriving at any distinct opinion. P. spongiosus, Klotsch, Herb. viv. Mye. No. 2, is

the same production.
414. P. rerrugrnosus, Fr.
416. P. sanicinus, Fr.
417. P. susspApicEus, Fr. We are unacquainted with the Friesian species.

418. P. sprssus, Schwein. This species, of which there are authentic specimens
in Hook. Herb., is totally different from the Friesian plant, which we believe that
we have from 8. Carolina. The pores have the same resinous appearance as in P.
Pilote, Schwein. In the Schweinitzian Herbarium it is marked P. rufus.

419. P. unpatus, P. This differs from the plant of Persoon, of which we have an
authentic fragment, in the far larger pores. In-color it agrees with it.

420. P. NiEskyensis, P.

421. P. umprinus, P. Certainly not the same with P. obliquas. We cannot
distinguish it from P. ferruginosus.

422. PB. JueLanpinus, Schwein.! Certainly different from P. spissus of Hook. Herb.

423. P. vittcoLaA, Schwein.! Resembles P. contiguws, and perhaps not really
different, though totally distinct from P. superficialis.

424. P. xantuus, Fr. Totally different from authentic specimens of the Friesian
species, but exactly agreeing with a specimen under the same name from Desmaziéres,
except that it is not at present stratose. It somewhat resembles resupinate forms of
P. annosus, except that the pores are smaller. We have the true P. wanthus from
S. Carolina.

212 BERKELEY AND CURTIS'S COMMENTARY

425. P. nrripus, Fr. We have two species under this name,—one from Schweinitz’
earlier collections, which appears to be a state of his P. migro-purpurascens, and the
other with long pores, very different from an authentic specimen now before us.
This was formerly called P. croceus by Schweinitz, but that name is preoccupied.
We beg to substitute

P. CROCIPORUS, n. sp.;—totus resupinatus; poris minutis longis tenuibus, extus
intusque croceo-fulvis, mycelio pallido molli oriundis.

The pores are just the color of dried saffron, and have somewhat the same appear-
ance as those of P. spissws. The mycelium is pale, thin, of a rather soft texture and
confluent with the matrix.

426. P. puLcHELLUS, Schwein. The same with P. xanthus, Schwein.! Herb. As
P. pulchellus was formerly called P. xanthus by Schweinitz, it is possible that we
have not got what he ultimately intended by that name, and which may therefore
be the true plant. ;

428. P. incARNATUS, Fr. The young state of some Gleoporus.

430. P. RuopELLUS, Fr. Not the true plant of Fries, as appears from an authentic
specimen. It looks like an early stage of P. spissus, Schwein.! in Hook. Herb.

431. P. unirus, Fr. The Schweinitzian specimens are precisely the same with
No. 418. ;

4§2. P. viTELLinus, Fr.
434. P. sinuvosus, Fr. We have no authentic specimens of this species.
435. P. XANTHOLOMA, Schwein.! Very distinct.

436. P. rHopopENDRI, Schwein. ! Very like P. Stephensu, Berk., which has been
found on Taxodium by Mr. Ravenel. This differs in its thinner dissepiments and
obscure tint.

437. P. SASSAFRAS, Schwein.! Schweinitz describes this in his Herbarium as
having “pori majusculi,” which agrees with the specimen; whereas the printed
character says “poris minutis.” It is probably a distinct species.

438. P. SUPERFICIALIS, Schwein.! An authentic specimen from Prof. Torrey’s
Herbarium has nothing like “poris latiusculis,’ and we believe is identical with
No. 439.

439, P. NIGRO-PURPUREUS, Schwein, !

440. P. cingErEuUS, Schwein.! The specimens of this, as of some others among the
omitted numbers, are destroyed.

ON SCHWEINITZ’S SYNOPSIS FUNGORUM. 213

441. P. CARy&, Schwein.! Resembling somewhat P. xantholoma, but with rather
larger pores.

442, P. papyracrus, Schwein.! Pores rather large; resembles P. Stephensii, Berk. .
444, P! MEDULLA PANIS, Fr.

445. P. tupercuLosus, Fr. Apparently a Radulw.

446. P. virreus, Fr. The specimens belong to P. vulgaris.

447. P. vutearts, Fr. Not the true species, but closely allied to P. pulchellus,
Schwein., only with smaller pores. We can see no other difference. The same
Fungus occurs in Ohio and N. Carolina.

448. P. cancrus, Fr. 8. A curious production, resembling somewhat a Porothelium,
but scarcely in a normal condition.

449. P. cautosus, Fr. The specimens are hardly distinguishable from P. pulchellus,
Schwein., and do not answer to the description of Fries. - We have, however, the
Friesian species from S. Carolina.

451. P. couticutosus, P. We are not acquainted with this species.

452. P. oppucens, P. This is not in the least degree stratose. The pores are a
line long. It appears to us to be very near to P. xantholoma.

453. P. pentirporus, P. Very much after the fashion of P. vaporarius, and indeed
scarcely to be distinguished.

455. P. rerrestris, Fr. This is scarcely the plant of Fries, and perhaps is unde-
scribed.

456. P. tenuis, Schwein.! Resembling P. vaporarius, but more uniform. What
was referred to this species in the account of Mr. Lea’s Ohio Fungi is something with
much broader and shallower pores, and is scarcely developed fully.

457. P. mucipus, Fr.
458. P. RADULA, Fr. Certainly P. vaporarius.

459. P. micans, Fr. Another form of P. vaporarwus.

461. P. SANGUINOLENTUS, Fr. There are two things under this number. One is
the same with 430; the other answers exactly to P. reticulatus, Fr.

462. P. motuuscus, Fr. The sulphur-colored variety of which Schweinitz speaks
is much in the fashion of P. reticulatus, and is probably undescribed.

463. P. FARINELLUS, Fr. Our specimens of this are nearly destroyed by insects.

464. P. annirinus, Fr. The specimens are not quite certain, but the species
occurs in a highly developed state in S. Carolina.

465. P. xytostromeus, P. Two things are in the Herbarium under this name:
the one appears to be merely a state of P. vaporarius; the other is a species of
Merulius. See below under No. 500.

469. P. InTERNUS, Schwein. !

471. P. reticuLatus, Fr. This appears to be certainly P. farimellus, of which we
have fine specimens from S. Carolina. It has not a byssoid margin, nor are the pores
distant.

*P. BRUNNEUS, Schwein.! New York. This appears to be the same with P.
crocatus, Fr., which is very near to, if not identical with, P. cupreus, Berk.

473. POROTHELEUM SUBTILE, Fr.

475. P. PrzizowwEs, Schwein.! This species differs from P. fimbriatum only in the
absence of the marginal threadlike processes. There is a species in Hook. Herb.
from Schweinitz marked Boletus obliteratus.

476. DA&DALEA BIENNIS, Fr.= Polyporus rufescens, Fr.
480. DADALEA ABIETINA,= Lenzites abietina, Fr.
481. D. TRABEA,= Lenzites trabea, Fr.

483. D. Pint, Fr. The specimens belong to Lenzites sepiaria, perhaps from an
accidental change of the label.

A490. D. aneustata, Fr.
491. D. AUREA, 2. FERRUGINEA—Lenzites sepiaria, var.

492. D. zonata, Schwein.! This is considered by Fries to be D. variegata. Our
specimens are too imperfect to allow us to form any judgment on the point.

494. D. MERULIOIDES, Schwein. This is a Paxillus, but our notes upon the speci-
men are too meager to enable us now to recal the species.

495. MERULIUS TREMELLosUS, Fr. The plant in Hook. Herb. from Schweinitz,
under the name of MM. tremelloides, seems nearer to M. fugax, of which we have very
fine specimens from 8. Carolina. It is accompanied by Sclerotium rugulosum, (No.
2436,) and therefore must be what Schweinitz intended. See that number.

496. M. srricoso-zonatus, Schwein.! This is Phlebia zonata, B. & C., a very
distinct species.

499. M. crispatus,Fr. Thisisclearly a form of MZ coriwm. M. crispatus resembles
Cantharellus crispatus.

506. M. Himantiores, Fr. The specimens belong to IZ. Brassicefolius, Schwein.,
a name not preserved in the Herbarium.

507. M. Portnores, Fr. We have fine specimens of this species from Ohio. It
occurs also in S. Carolina. Schweinitz specimens are all but barren, and the slight
trace of incipient folds indicates rather a state of I Coriwm or M. serpens.

524. H. connatum, Schultz. The Schweinitzian specimens have not a shining
stem, and do not seem to differ from H. zonatum, Batsch.

526. H. CORIACHO-MEMBRANACEUM, Schwein.! A very singular and distinct species.

540. H. otrvAcrum, Schwein.! The specimens belong to Lrpex cimnamomeus.

541. H. macropon, P. The species of Persoon is but little known. The Schwein-
itzian specimens closely resemble A. mucidum.

542. H. mMemBrANAceum, Fr. The Schweinitzian specimens are altogether different
from the Friesian. In fact we do not find the species which they represent described,
and therefore characterize it as follows: J. Schwemitzn, B. et C., papyraceum,
album, a matrice omnino solubile; aculeis sparsis subulatis, basi abrupte dilatatis.

543. H. rusco-atrum, Fr.

544. H. rERRUGINOSUM, Fr.

545. H. micropon, P. The original plant is a subterranean species, altogether
omitted in the Epicrisis. ‘The fragments of the Schweinitzian plant before us seem to
agree fully with H. membranacewm, Bull.

546. H. atutaceum, Fr. This is very different from the plant of Fries, of which
we have authentic specimens. It seems to be a young state of H. udwm.

548. H. mucipum, P. Extremely different from authentic specimens. It appears
to be the true H. alutacewn.

564. H. rivpriatum, P.= Odontia fimbriata, Fr.

565. H. spatauLatum, Fr. Quite different from Schweinitz’ specimens under this
name in Hook. Herb. It appears to be some Polyporus with lacerated dissepiments.

566. H. quzrcinum, Fr. This is perhaps Jrpex obliquus, Fr., certainly not Radulum
quercinum. Some states of J obliquus are, however, very difficult to distinguish from
Pol. vaporarius.

569. H. strpatum, Fr.

570. H. cInNABARINUM, Schwein.! This is the same with Odontia albo-miniata,
B. and C., and is only a peculiar condition of Pol. cinnabarimus.

positive about them. :

We have collected specimens precisely similar extending from stumps over fallen

583. I. Curasi, Fr.—J paradoxus, Fr. The pores, however, are more developed
than in our authentic specimen, and the dissepiments thinner.

584. I. spATHULATUS, Fr. We have no doubt that the specimens belong to Pol.
vaporarius. Fries says of I spathulatus, “nunquam porosus,” which does not at all
apply to the plant before us. Indeed there is no resemblance between it and a Swiss
specimen from Trog.

whether the reference is right. The species, however, in the Schweinitzian Herba-

Corticvum.

696. T. seticeRA, Fr. The plant of Fries now forms the genus Kneifia. The
plant of Schweinitz is either a blanched state of Corticiwm velutinum or distinct.
The only difference, however, is one of color.

Cort. sulphureum and is marked by Schweinitz Contophora sulphurea.

698. T. pAPiILLosA, Fr. This is not a Grandinia, for there is not the slightest ap-
pearance of granules. It is perhaps only a form of Cort. leve.

699. T. GigANTEA, Fr. Very doubtful. It is in fact the same with 7. viscosa from
Mauch Chunk, which is so marked by Schwein. in Herb.

The following should be added to No. 374 :—

There is in the Hookerian Herbarium a species from Schweinitz marked Sistotrema
velutinum, and we have the same from Prof. Torrey’s collection of Schweinitzian Fungi
marked Polyporus velutinus, which is probably the plant intended under No. 374. . It
does not, however, accord with numerous authentic specimens from Fries, and we pro-
pose for it the name of Pol. Richardsonii, as it occurs in his collections from the higher
northern regions of America.

ART. XVIII.—Synopsis of the MELotontuips of the United States.
By Joun L. Lz Contes, M. D.

The Melolonthide form a group of the family Scarabzeide less distinctly defined
than any other in that extensive family; connecting with several others, it seems to
be the great central group, and embraces genera of such diverse form and structure,
as to render the attempts at classification not altogether satisfactory. Hrichson was
the first to attempt a general arrangement of the tribe, and Lacordaire, while following
nearly in his path, has introduced some important changes. It would ill become me,
having studied only a fauna limited in genera of this type, to pronounce upon the
value of the affinities thus displayed between genera which I have never seen; but I
have found great difficulty in placing in the schemes of those authors a new genus,
which should evidently have place within the limits embraced by them.

The classification of Burmeister is founded upon entirely different characters, and
seems at first to give much more natural groups than those formed by Erichson and
Lacordaire, though the characters used seem by no means distinct or easy of applica-
tion. The great stumbling point in both systems is however the curious mixture of
characters found in the allied group Anthobia of Burmeister, part of which forms
Hrichson’s family Glaphyrid, enrolled in the great series of Scarabzi laparosticti.
Burmeister having examined (Lamell. 2, 2d, 467) the position of the abdominal stig-
mata in the genera of Hrichson’s Glaphyride, found great variations between the
individual genera, some having them as in Melolonthid, while in none had they
exactly the situation in which they are found in the other groups of Laparosticti.
From these facts he draws the inference that the family Anthobia as established by
him is a natural one, osculant between the Phyllophaga (Melolonthide and Rutelide
of Erichson) and Melitophila (Cetoniade of Erichson), entirely denying the relation-
ship with the Laparosticti.

While admitting the probable justice of the latter result, although Erichson notes
the transition from Pheenognatha to Hybosorus, I must say that the facts seem to me
_to bear a very different interpretation. Looking for example at the four primary
groups into which Hrichson divides the, Scarabs pleurosticti, the reader will see that
the Melolonthidx have the posterior stigmata diverging but feebly, while the three
others have them diverging strongly. We will afterwards see that the position of

08

SES a One

226 LE CONTE.—SYNOPSIS OF THE

the posterior pair in the groups of genuine Melolonthide varies. Why, then, may
not all these cases of variation, great or small, in the position of the stigmata be
brought together in one large group, which may be placed between the pleurosticti
and laparosticti, connected more closely with the former than with the latter. The
essential character of this large group seems to be the negation of the characters of
the other two; and we would thus have the following expression of relations :

Stigmata abdominis in segmentis ventralibus sita postice fortiter divergentia, ultima
conspicua . : : 5 ; 6 ; é : : : ; 5 6 . Laparosticti.
Stigmata abdominis parum divergentia, variabiles, at in membrano non sita, ultima saepe
conspicua . ; 2 ; : ; : A i ; : ‘ ; F - Melolonthidee.
Stigmata abdominis in membrano inter segmenta ventralia et dorsalia sita, ultima obtecta Pleurosticti.

Besides this difficulty in determining the limits and characters of the entire family,
some difference in observation appears to result from the nature of the characters
used in its division. Thus, for example, the ventral segments of the Sericide are
described as free by Erichson and Lacordaire, and as connate by Burmeister; the
sutures are in reality distinct, though probably immovable. Nevertheless, although
so deceptive, this character cannot in the present condition of the study be abandoned,
though perhaps something may be done to render it more reliable.

Modifying the tables of Erichson and Lacordaire to suit the introduction of the new
views enunciated above, and omitting the groups not found in our territory, the
following table may be formed :

1. MACROPHYLLA.

A group having the epimera and parapleurse of the metathorax broad as in Melo-
lonthe, but differing by the ventral segments not being connate, although the sixth
is less closely articulated. Besides this character, the long slender tarsi, and the
very long hair of the head, thorax and sides, enable them to be readily recognized.
The group has heretofore had no representative on the American continent, but I am
now enabled to make known a new genus found within our territories.

Characters derived from the abdomen, and not mentioned by Burmeister or Lacor-
daire are the very distinct and straight fissure-like suture between the fifth ventral
seement and the propygidium; the stigma is situated on the ventral segment, near
the anterior margin, but remote from the suture just mentioned.

The group in its present form was established by Lacordaire. It consists of the
eroup Tanyproctini of Hrichson, less the genus Tanyproctus.

Burmeister combines with it Krichson and Lacordaire’s group Pachypodii, which
differ not only by the variable characters derived from the less development of the
oral organs, but by the epimera of the metathorax being narrow.

Seems to be allied to Tryssus Hr. and Trichiodera Burm., but the latter has 10-
jointed antenne; the former has, it is true, 9-jointed antennz, but is very insuf-
ficiently described, and being from southern Africa can hardly be the same as the

present genus.

apex, and a faint fovea near the side at the middle; the anterior angles are acute.
The oral organs, sides of the head, and base of the antenne are also provided with
long hairs.

2. MELOLONTH A.

This group differs from the others by the combination of the following characters :
five ventral segments of the abdomen are connate, with nearly effaced sutures, the
6th is distinct and rounded ; the parapleure of the metathorax are broad and their
epimera are large.

The latter important character was first observed by Lacordaire, (Gen. Col. 3, 292),
but has been overlooked by Burmeister, who distributes the contents into two groups,
Leucopholidez having the third joint of the antenne short, and Polyphyllide having
the same joint elongated. The new genus Thyce, while important as being the
second generic representative of the group on this continent, is still more important,
as showing the greater correctness of the view taken by Lacordaire, since with the
habit and structure of head and feet of Polyphylla, it combines the antenne of Leu-
copholis.

Additional characters common to our two genera, but which, though apparently
of importance, are not mentioned in the generic descriptions of Burmeister, are, that
the middle tibize, instead of being surrounded externally by two more or less developed
crowns of spines, (as in all Rhizotrogide), are acutely bidentate; the posterior tibize
of Polyphylla are similar to the middle ones; in Thyce the inferior prominence is
transverse; the suture between the fifth ventral segment and the propygidium is dis-
tinct, angulated at the middle, with the stigma placed exactly upon the angle; the
thorax is not margined anteriorly, and is ciliate with short bristles.

Our two genera are very distinct, and may be thus known :

Kansas, Nebraska and New Mexico; shores of Tlamath Lake, Oregon, Dr. New-
berry ; a specimen of very large size was found by Mr. Joshua Child in the Sierra
Nevada of California. The head behind is clothed with moderately long hair, but
hardly any is seen on the thorax ; the yellow scales on the latter near the margin are
elongate, but on the disc they are lanceolate, and about twice as long as their width ;
the sides are obtusely angulated at the middle, with the posterior angles very obtuse.
The yellow scales of the elytra are acute, and a little more than twice as long as their
width. The under surface is clothed with pale scales with snowy bands across the
abdomen ; the pectus is very hairy, the posterior tibize are internally clothed with
long hair. The feet vary from ferruginous to blackish.

A male found in Kansas is remarkable for the right antenna bifurcating at the end
of the second joint; the inner third joint is thick and short, the outer normal; the
outer club is normal, but smaller than the one of the opposite side; the inner club is
deformed, being composed of two which are fused together at the middle, forming a
concave mass, of which the upper laminze are much longer than the under ones. The
anterior tibize are almost without teeth.

Oregon, Washington Territory and California. So similar to the preceding that the
females might be readily confounded ; on comparison, however, I find the following
differences independent of sex. The yellow scale-like hairs are lanceolate, and narrow,
being on the elytra about four times as long as their width; on the disc of the thorax
especially in the vittee they are broader, but towards the margins they are elongated,
and are gradually converted into long hairs, which towards the apex are as long as
those on the back of the head: the sides of the thorax from a dorsal view appear
rounded, and not angulated.

The base of the thorax of the male is densely fringed with long yellowish hair, about
three-fourths as long as the scutellum, but in the female the hair is not longer than
in both sexes of P. 10-lineata. The under surface is as in the preceding; the legs —
are however ferruginous in every specimen before me: the margin of the elytra, the
pygidium and last ventral segment are also usually ferruginous.

The study of the genus Lachnosterna indicates that in this tribe species may be
really distinct, although almost without differences in form and sculpture, otherwise

T should not venture to distinguish the present by a specific name, but should rather
class it as a race of P. 10-lineata.

founded by Erichson and Burmeister with the following, to which it bears but little
resemblance ; or at least the name has been quoted as a synonym, without any know-
ledge of the object or figure to which it referred. Apart from the want of regular
vittze on the elytra, the pubescence is much less dense, the occiput clothed with long
hair, the thorax is shorter, and more narrowed anteriorly and more rounded on the
sides, the body is less elongated, and much less cylindrical than in the next species.
The abdomen is sometimes fuscous, sometimes reddish brown, with bands of whitish
pubescence.

scales. Pectus densely clothed with long yellowish hair. Femora and inner margin
of the posterior tibiz fringed with long hair.

3. RHIZOTROGI.

These are distinguished among the other Melolonthide with transverse not promi-
nent anterior cox, by the deeply emarginate labrum, the anteriorly margined thorax
without apical membrane, the narrow parapleure, and the connate ventral segments.
Specimens, and perhaps even species occur in which this last character is not very
obvious. |

Additional characters, not previously noticed are: the 5th ventral segment is joined
with the propygidium by an angulated suture, which is sometimes partly obliterated,
the stigma is paced upon the suture at the angle, and nearer the posterior than the
anterior margin.

The last joint of the maxillary palpi is frequently impressed and sometimes deeply
excavated, the ungues and mandibles seem to vary in form within the same genus.
In the native genera the posterior coxse are entirely corneous, without any posterior
membranous margin: the posterior external angle is sometimes produced ; the antennze
are 9 or 10-jointed, with the club three-jointed.

Our genera may be thus arranged :

Unguiculi haud serrati, prope medium dentati ;

Ligula profunde emarginata ;
Antenne 10-articulate : ° : : : : : : Eugastra Lec.
Antennz 9-articulatee : ; ; : : : : ; : Endrosa Lec.

impresso.

This genus represents on this continent the apterous Rhizotrogi of the group Geo-
trogus, but differs from that genus by many characters. The deep emargination of
the ligula is bisinuous but almost square at base, and will readily distinguish this

from all the other genera of the tribe.

LACHNOSTERNA Hope.

This genus commonly appears under the name Ancylonycha, and in the Catalogue
of the Described Coleoptera of the United States is called Phyllophaga. After care-
fully examining the history of each of these names, I am convinced that aregayd for
the purity of nomenclature requires that they should be rejected, and the name pro-
posed by Hope in 1837, (Coleopterist’s Manual, 1, 99) should be restored.

The name Ancylonycha, the one best known, is used for the first time by Dejean,
in the Catalogue of his Collection printed in 1833, but the characters were first pub-
lished by Blanchard, in 1845, and the name was subsequently adopted by Erichson,
Lacordaire, Burmeister, and all the leading entomologists of Kurope.

Misled by a note in the first edition of Harris’ Insects of Massachusetts Injurious to
Vegetation, (p. 30,) the name Phyllophaga was adopted by Mr. Haldeman and my-
self in the Melsheimer Catalogue, as above stated, but by the kindness ofa friend I
have recently procured a transcript from the Massachusetts Agricultural repository
cited by Harris, and find that the name, although proposed as early as 1826, is not
accompanied by any description.*

* For the convenience of future students, I reprint the passage in which the name is proposed. Vide Mass.
Agricult. Repository, vol. x. p. 6, (note.)

«The genus Melolontha as constituted by Fabricius contains a vast number of species, differing greatly in ex-
ternal appearance, and somewhat in modes of life. Fabricius describes 149 species, and Schénherr, after separat-
ing those which constitute the modern genera Anisonyx, Glaphyrus, Amphicoma, Rutela, and Hoplia, enumerates
226 species of Melolontha, to which additions are constantly making from the discovery of new species. Hence
the genus requires further subdivision. The bases of these subgenera have been pointed out by Latreille, Knoch,
and Schéunherr, and some have already been established. I would restrict the name of Melolontha to those
species which have more than three lamellz to the club of the antenne, like the vulgaris of Europe, and of which
we have an indigenous example in the M. decimlineata, of Say, (M: occidentalis Herbst?). Our common species

quercina, hirsuta, hirticula, balia, and some others might receive the generic name, Phyllophaga. M. vespertina

236 LE CONTH.—SYNOPSIS OF THE

From this it is clear that the name Ancylonycha is the one entitled to least regard,
since it the more recent, among the uncharacterized as well as among the char-
acterized names.

The species are very numerous, and many of those recently discovered in the South
Western territories of the United States present some very curious characters in the
spurs of the posterior tibize, which render the establishment of several groups easy.
The form of the ungues, and the prominence of the mandibles in a state of repose are
characters subject to much variation. Following the example of Lacordaire I have
suppressed the genus Tostegoptera Blanch. founded on Mel. lanceolata Say, and
Trichesthes Hr. as being distinguished by insufficient characters.

The species naturally divide themselves into four principal groups; of these the
most numerous is distinguished by the inner spur of the posterior tibiee being in the
male connate with the tibiz, and by the comparatively large sixth ventral segment
being somewhat rounded in front so as to invade the fifth. These would seem to be
characters of some importance, and a careful study of the species from Asia and South
America may shew the necessity of regarding them as generic, in which case Trichesthes
must be retained for division D; division A. will keep the name Tostegoptera, and C. if
differing from the Asiatic species called H olotrichia by Hope must receive a new
name. In that event, however, as at present the following grouping exhibits the
relations of our native species.

sericea and tricolor would form another sub-genus which might be called Stilbolemma, unless they are included
in Serica MacLeay, or Omaloplia of Megerle ; the characters of their genera I have not seen. M. pilosicollis,
longitarsa, and moesta of Knoch and Say should each constitute a subgenus. The latter (with M. sordida and
frondicola Say ?) belongs to Kirby’s genus Apogonia. From the singular manner in which the nails are divided
at tip, I would call the linearis of Schénherr Dichelonyx.’

Ibid, vol. x. p. 8. (Note.) |

‘ Stenothorax would be an appropriate name for the subgenus having the svbspinosa for its type.

Scarabeeus lanigerus, Linnzeus Melolontha lanigera, Fabr. has been referred to the genus Rutela ; but Schoaherr
says it is not a Rutela, and arranges it between M. fastwosaand M. aurata F., belonging to the genus Anomala?
it may therefore be considered as the type of a new subgenus. See Schonherr’s Synonymia Insectorum, HT. p.
504. Scarabzeus punctatus, Lin., Melolontha punctata Fabr., or Rutela punctata, Latreille, belongs to Mr. Mae-
Leay’s genus Pelidnota.
Melolontha varians Fabr. is congeneric with the Anomala vitis of Megerle and Koppe.’

Male with the club of the antennz as long as the stem, the abdomen with a broad
longitudinal impression not extending upon the last segment, posterior tibize with the
spurs free, very broad, flat and obtuse: tarsi longer than the tibie.

Female with the abdomen not impressed ; the posterior spurs as in the male, and
the tarsi hardly longer than the tibia.

Group III.

This group is established upon a single species, having most of the characters of
the preceding, but the form is oblong and the spurs of the posterior tibise are con-
torted (at least in the male) and not flattened. The antenne are 10-jointed, the
mandibles and palpi as in the preceding, the clypeus is strongly margined, hardly
emarginate. The thorax is rounded on the sides and serrate, but only very slightly
narrowed at the base. The breast is moderately hairy, and the claws are toothed
near the base : the spurs of the posterior tibie of the male are free, the inner (lower)
one is curved, almost in a semi-circle, and inserted on the edge of the tibia, the upper
one is straight and prismatic, inserted upon the end.

Two males collected in Texas by Messrs. H. Haldeman, and Lindheimer. The
propygidium is opake, sparsely punctured, the pygidium is shining, more strongly
punctured and subtruncate at tip: the abdomen is tolerably strongly punctured.

The club of the antennz of the male is hardly as long as the stem; the abdomen
is longitudinally flattened, and the penultimate segment is roughened and slightly
elevated transversely at the middle near the posterior margin; the inner spur of the
posterior tibize is laterally inserted and curved in a semicircle, the outer one is shorter,
pointed, thick and three sided: the tarsi are longer than the tibie.

Group IV.

This group consists of small cylindrical species, glabrous above. The head is large,
the clypeus is entire in one species, and deeply emarginate in the others: the mandi-
bles project beyond the labrum: the last joint of the maxillary palpi is oval, nearly
pointed, not impressed externally in all but volyula, where it is cylindrical and
slightly impressed. The antenne are 9-jointed, with the joints 3—5 connate, the
6th slightly produced inwards. The last joint of the abdomen is tolerably large,
merely flattened and not impressed in the males. The inner spur of the posterior
tibis of the male is fixed, and straight in the species here described. The tarsi
especially of the males are very long, and the claws are armed with a small tooth in-
side of the middle.

In the male the club of the antenne is as long as the stem, the abdomen is slightly
flattened longitudinally, and the penultimate segment has a small posterior lunate

impression at the middle ; the inner spur of the posterior tibiz is very small and fixed,

but the outer one is long and flattened.

Southern States. More robust than the preceding, and approaching in form those
of the next group. Burmeister describes the male as fuscous on the upper surface ;
the only two specimens in my collection are males, but are of a reddish yellow color
both above and beneath ; only the head is dark.

The club of the male is longer than the stem of the antennz; the three anterior
segments of the abdomen are longitudinally impressed and the last segment is slightly
swollen: the pygidium is slightly transverse and strongly punctured ; the inner spur
of the posterior tibise is fixed, one-half the length of the outer, which is slender.

Group V.

Containing cylindrical species having the body glabrous above, and beneath only
slightly pubescent, even on the breast. ‘The head is large, being scarcely one fourth
narrower than the thorax; the clypeus is strongly margined, sometimes entire, some-
times emarginate. ‘The mandibles project beyond the labrum when closed. The last
joint of the maxillary palpi is variable in form, but is always more or less oval, and
flattened or impressed along the outer part. The antenne are 10-jointed, with the
joints 8—5 connate and indistinct, the sixth and seventh are slightly produced inwards.
The thorax is remarkably broad, not narrowed behind, nor serrate on the sides. The
last joint of the abdomen is relatively smaller than in the other groups having the
inner posterior spur of the male fixed, but in the male is impressed and emarginate.

Georgia. This species has precisely the form of the preceding, but the head is
more coarsely and less densely punctured.

The male has the club of the antenne longer than the stem; the abdomen faintly
channeled, the penultimate segment faintly impressed and roughened at the middle,
with the posterior margin not emarginate as in the two preceding, with a very
slight oblique discoidal elevation each side towards the middle; last segment with a
very deep round fovea, bounded each side by an elevated ridge, which, however,
hardly rises into a cusp, as in L.cerasina. Posterior tibiz: with the terminal
fringe of spines longer than usual, with the inner spur distinct, but not larger than
one of the spines ; outer one long, slender.

A female which I refer to this species has the head much smaller, being only two-
thirds the breadth of the thorax, the eyes small and distant, and the spurs of the
posterior tibize long and nearly equal.

One female, New York, Mr. Guex. Much smaller than the preceding, but similar
to it in characters; nevertheless, the clypeus and thorax and elytra are more punc-
tured, the scutellum is strongly punctured, and the elytra are not costate, even near
the margin. The pygidium is subtriangular, shining and sparsely punctured. The
breast is very slightly pubescent, and the claws are armed with a small tooth at the

middle. The penultimate ventral segment is faintly impressed transversely, and the
last joint is slightly emarginate at tip.
Group VI.

In this group we havé a species of oblong form, glabrous upper surface, and 10-jointed
antennz; the clypeus is slightly emarginate, the mandibles are but little prominent,
the last joint of the maxillary palpi is distinctly oval, but has no lateral impression.
The thorax is not narrowed at the base, and is hardly serrate on the sides: the upper
spur of the posterior tibize of the male is fixed, laterally inserted and is oblique, thus
causing the apical portion of the tibiz to be emarginate beneath: the upper spur is
flattened and acute: the claws are armed with a short acute tooth at the middle.

New York, Georgia, and Texas. The pygidium is sparsely but strongly punctured.
Only males are known to me, and in them the club of the antenne is longer than the
stem, the last three segments of the abdomen are broadly and deeply channeled, the
penultimate has a deep posterior longitudinal line, and the last a triangular space
limited each side by a sharply defined edge; the outline of the apex is sinuous, and
has two small lobes at the middle. The inner posterior spur is straight, not shorter
than the outer, but oblique and connate, inserted upon the side, so as to produce a
deep inferior emargination.

Group VII.

Contains a single oblong convex species, which, although glabrous above, is fringed
on the margin with long erect hairs. The head is moderate, the clypeus narrowly
margined, slightly emarginate; the antennz are 10-jointed, the last joint of the
maxillary palpi slender, not. impressed. The thorax is not narrowed behind; the
breast is clothed with long dense hair; the inner spur of the posterior tibize of the
male is very long and irregularly bent, the outer one is equally long, but straight
and slender ; the tarsi are long, and the claws armed with a long tooth a little beyond
the middle, so as almost to appear cleft.

Lake Superior, New York, Kansas; only males seen. Body oblong, convex ; head

rounded, serrate and fimbriate, dorsal line smooth but not very distinct. Scutellum
sparsely punctured. Elytra strongly rugous and punctured, with a faint trace of the
inner dorsal costa, but no outer ones: margin fringed with long erect hairs. Pygidium
convex, sparsely strongly punctured. Breast densely clothed with long yellow hair.

The male has the club of the antenne longer than the stem, the abdomen longi-
tudinally impressed, the penultimate segment with a faint transverse elevation, and
the last segment with a large fovea bounded posteriorly each side by an acute edge
extending to the apex; inner spur of the posterior tibie very long, slightly sigmoid,
dilated into an oblique narrow disc at tip.

As frequently happens, when isolated species are described before the group to
which they belong has been studied, the original description given by me makes no
mention of the most remarkable characters of this species.

Group VIII.

This is the central group of the genus, and contains a large number of species,
which seem in some cases to be so closely allied as to be undistinguishable, thus pre-
senting the phenomenon of races, of which the examples are already so numerous in
this as in every other department of Natural History. The body is glabrous above,
and sometimes pruinose ; the head is small, or moderate in size; the clypeus is more

or less emarginate, though in L. serricornis it is entirely rounded. The thorax is
usually gradually broader from tip to base, but sometimes its widest part is at the
middle. The fifth ventral segment is broadly emarginate, and in the male is
variously impressed, while the last of the same sex is widely but not deeply exca-
vated. The ungues are variable in form, even between closely allied species. The
inner spur of the posterior tibize of the male is straight and connate, while in the
female both are free, and not very unequal.
According to the form of the clypeus and the sides of the thorax, the following
division may facilitate the determination of the species:
* Thorax not or hardly serrate, clypeus strongly margined é - ; : Sp. 16—21.
** Thorax not or hardly serrate, clypeus finely margined, but more deeply emarginate Sp. 22—30.
Thorax angulated on the sides, strongly serrate, clypeus as in ** 5 : Sp. 31—34.

villoso, antennis pedibusque ferrugineis. Long. ‘78 —-97.

MELOLONTHIDA OF THE UNITED STATES. 245

A very common and through Atlantic America widely extended species, em-
bracing several races, to which, however, no definite characters can be given. 'The
color varies according to the maturity of the specimen, but usually the whole under
surface is ferruginous ; the last ventral segment of the male hasa broad round impres-
sion, and the penultimate is transversely impressed and elevated. The tooth of the
claws of the tarsi in the male of the normal race is one-half shorter than the apical
part ; the club of the antennz is as long as thestem. In the female the clubis small,
and the tooth of the claw is as long as the apical portion. The elytra are sometimes
very finely rugous without punctures, sometimes very finely and sometimes quite dis-
tinctly punctured ; the costz are usually obvious. The sides of the thorax are some-
times slightly, sometimes very strongly rounded; the punctures are distinct but not
large nor dense, sometimes a smooth dorsal line is left. The clypeus is usually dis-
tinctly, though slightly emarginate, but in some specimens the undulation is hardly
perceptible.

The principal races are as follows:

a. Body nearly cylindrical, thorax much rounded on the sides; elytra finely and densely punctulate ;
male with long tooth on the ungues. J. consimilis Lec. Agassiz’ Lake Sup. 226.

8. Body slightly ovate, thorax with the sides oblique and rounded, narrower than the elytra; male with
ungual tooth short.

y. Body ovate, thorax strongly punctured with the sides oblique and rounded, shorter than’ usual, nar-
rower than the elytra, which are strongly punctured. JL. unxia Lec. Agass. Lake Sup. 226. A. brevicollis
Blanch. Cat. Col. Mus. Paris, 132.

§. Thorax narrower than the elytra, almost angulated on the sides, finely sparsely punctured, elytra
moderately punctured ; claws of the male with long tooth. A. brevicollis Burm. Lamell. 2, 2d, 322.

z. Body hardly ovate, thorax slightly narrower than the elytra, much rounded on the sides, elytra dis-
tinctly and sometimes strongly punctured; claws of male witha long tooth. Ancylonycha puncticollis
Blanch. Cat. Col. Mus. Par. 133.

n. Larger, body subcylindrical, thorax very much rounded on the sides, elytra finely and densely rugu-
lose and slightly punctulate. Male with along tooth on the claws. Mhizotrogus Drakii Kirby, Fauna

Ancyl. profunda and uniformis Blanch. Cat. Col. Mus. Paris 132, 133,
which are considered by Burmeister to be varieties of this species, appear by descrip-
tion so different that I am not warranted in so placing them, though the characters
given are not such as to enable them to be distinctly recognized. The first mentioned
is perhaps allied to L. Knochii.

A male specimen from Wisconsin, belonging by form and sculpture to 7, shows a
remarkable sexual peculiarity in the penultimate abdominal segment, the elevation on
which is very sharply defined and quite curved; in all the other males I have seen
the elevation is straight, although sometimes very slightly emarginate.

One specimen found at Fort Riley by Mr. de Vésey. ‘This species has nearly the
form of the common varieties of the preceding, but the punctures of the head, espe-
cially towards the side, support short erect hairs; the punctures of the thorax are
stronger than usual in that species, and those of the elytra are not dense but strongly
marked.

The antennz are yellow, and the club of the male is a little longer than the stem ;
the abdomen is broadly impressed longitudinally, and the penultimate segment has an
obtuse transverse elevation at the middle; the moveable spur of the posterior tibie is
more slender than in L. fusca; the tooth of the claws is one-half the length of the
apical portion.

New York, Mr. Guex. This species and the preceding are nearly related, but the
present is more cylindrical in form, with the thorax more rounded on the sides, fringed
with long hairs, and narrowed only before the middle: the clypeus is also longer, not
emarginate, and more closely punctured ; and the elytra are finely and densely punc-
tured. The hairs of the head are sometimes rubbed off, in which case the specimen
assumes the appearance very nearly of L. sororia, but may be known by the long hairs
of the sides of the thorax and elytra; the sexual characters are precisely as in the
preceding.

Middle and Southern States, rare: of somewhat the same form as L. fraterna
and L. cognata, but more cylindrical, differing by the less emarginate but more
strongly margined clypeus, and by the sparse punctuation of the head. Care must
be taken not to confound it with a species (L. rufiola) having 9-jointed antennx,
which although resembling it entirely in form and sculpture, differs by the outer spur
of the posterior tibiz being less slender, and by the pygidium (of the female) being
somewhat conoidal. Body above dark reddish brown, very slightly pruinose, cylin-
drical, a little dilated behind. Head moderately punctured, front densely punctured,
clypeus with reflexed margin, very slightly emarginate. Thorax not twice as wide
as the head, about twice as wide as long, sides not serrate, converging slightly from
the base, but only broadly rounded, especially before the middle, surface equably but

Common in the Middle and Southern States. The only satisfactory difference I
find between this and the next species is in the form of the thorax, which is here
much more rounded on the sides, and slightly narrowed at the base. The other dif-
ferences noted by Burmeister, such as the greater concavity of the clypeus, the longer
hair of the pectus, and the finer punctures of the pygidium I do not find constant;
but fearing not to possess his species I have placed a query to the reference,

MELOLONTHIDA OF THE UNITED STATES. 249

The punctures of the thorax are variable, being sometimes strong and scattered, at
others finer and more numerous, but there is never any distinct smooth dorsal line.
The punctures of the elytra support very small hairs; the sides of the abdomen are
punctured, more distinctly on the last two segments; in the male the last one is
foveate, and the penultimate impressed in the middle, and the anterior segments are
slightly flattened; the club of the antenne is not longer than the stem.

Middle, Eastern and Southern States, abundant, as far west as Kansas. The sexual

_ characters are precisely as in the preceding, except that the penultimate ventral seg-

ment is more deeply impressed; the punctures of the elytra also support very small

One male from Georgia. Related by sculpture to the two preceding, but apart
from color, it differs by the head being not confluently punctured, and by the thorax being
more convex. The club of the antennz of the male is as long as the stem; the penul-
timate ventral segment is impressed with a slight oblique elevation each side of the
impression, the last segment is deeply foveate, and the anterior ones longitudinally

impressed, the last two segments are punctured, but the pygidium is only very finely
punctured, and the propygidium is smooth.

One maie, Texas, Mr. H. Haldeman. Remarkable for the characters of the poste-
rior tibize and tarsi, though otherwise allied to the preceding. Body oblong, slightly
narrowed in front, dark reddish brown. Head very densely punctured, clypeus emar-
ginate, with the margin narrowly reflexed. Thorax more than one-half wider than
the head, short, coarsely and subconfluently punctured, with various small spaces
smooth ; punctures smaller and more dense towards the apex, which is broadly foveate
each side; dorsal line smooth entire; sides hardly serrate, obtusely angulated, slightly
fimbriate. Scutellum with two groups of punctures. LElytra not shining, rugosely
punctured, with moderately distinct costs, margin slightly fringed ; pygidium sparsely
punctured, slightly flattened at the middle. Breast clothed with rather short but
dense yellow hair. Abdomen punctured; claws armed with an acute moderate sized
tooth at the middle.

The male has the club of the antenne as long as the stem; the abdomen broadly
concave, the penultimate with a deep posterior medial line, and two rough transverse
elevations near the anterior margin; the last segment is very broadly excavated ; the
inner spur of the posterior tibize 1s very short, broad, flat, obtuse and concave, the
outer one is long, flattened, and somewhat acute; the first joint of the posterior tarsi
is very much thickened and produced externally.

From the peculiar sexual characters I am inclined to believe that this should be
separated as a group, but not knowing the female, I cannot indicate any distinctive
characters applicable to both sexes.

sparsely covered with large punctures so placed as leave a large smooth space each
side of the middle. Elytra gradually widened behind, rugose and punctured, with
the usual faint coste, and a strongly marked submarginal one, extending nearly to
the base. Propygidium sparsely, towards the tip strongly punctured; pygidium
strongly punctured; abdomen punctured, more faintly in the middle; pectus clothed
with moderately long yellow hair.

The male has the club of the antennz longer than the stem; the abdomen flattened
in the middle; the penultimate segment with a semicircular curved elevation, and
middle fovea, and the last segment with a longitudinal broad furrow. The abdomen
of the female is almost uniformly punctured, the punctures of the last two segments
being stronger; the pygidium is triangular, and slightly conical at tip, while in the
male it is broader and convex.

This species is remarkable for the length of the submarginal elytral costa, which
in most species is seen only near the apex.

sides are somewhat serrate, and behind the middle are nearly parallel; the pygidium
is coarsely punctured, the propygidium is nearly smooth, with a few punctures as
usual at the margin. ‘The abdomen (of the female) is convex, punctured and pubes-
cent at the sides, more deeply on the last two segments ; the last one has a triangular
flattened impression at the middle; the pectus is thinly clothed with fine short
yellowish hair; the tibiee are dark brown, and the tarsi paler. Burmeister, not having

Two specimens from Platte River. According to the authors quoted, it is found in
Virginia and Pennsylvania. The propygidium is finely and sparsely punctured; the
sides of the abdomen are finely punctured, with the punctures larger on the penulti-
mate segment.

In the male the club of the antenne is as long as the stem; the abdomen is
flattened in the middle; the penultimate segment has a deep transverse impression,
and each side of it an oblique elevation ; the last segment has a broad reniform im-
pression, and the pygidium is broad and obtusely rounded.

In the female the abdomen is convex, the last segment is sparsely punctured, and

deeply squarely emarginate; the penultimate segment has a posterior deep tranverse
impression ; and the pygidium is triangular.

One male, upper Missouri, Dr. F. V. Hayden. Closely related to the preceding,
but the thorax is shorter, more narrowed in front, and strongly serrate on the sides :
the elytra are smoother, not rugose, with finer punctures.

Middle and Southern States, rare. The pygidium of the female is subtriangular
but not conoidal; the punctures are more sparse towards the apex; the sides of the
abdomen are punctured, and the penultimate segment has a strongly transverse im-
pression at the middle. The male is unknown to me, but the penultimate ventral
segment is described by Burmeister as having no transverse elevation, but a deep
impression.

Group IX.

The group contains a number of large oblong species having the upper surface
pubescent. The head is moderate in size, with the clypeus emarginate, not broadly
margined ; the thorax is broadest at the middle, and more or less narrowed towards
the base. The antenne are 10-jointed; the breast is clothed with hair. The ungues
are toothed at the middle, but the tooth is as long as the apical portion, so that the
form appears almost cleft. The spurs of the posterior tibie are straight, and the
inner one is fixed in the male; the penultimate ventral segment of the male is trans-
versely impressed, while the last joint is broadly foveate.

Ancylonycha fimbriata Burm. ibid.

Common in the Middle and Southern States; according to the maturity of the
specimen the color varies from blackish fuscous to reddish brown, but the glaucous
lustre is always distinct in well preserved specimens, and the legs are ferruginous. In
the male the club of the antennz is as long as the remaining portion; the hair above
is finer and less dense, but the hair on the breast is a little longer than in the female ;
the penultimate ventral segment is deeply transversely impressed, and the last joint
marked with a broad round impression.

The present species agrees with the figure and description of Knoch, and is also found
as the type in Dr. Melsheimer’s collection. That described by Burmeister is some-
thing different, and has not yet fallen under my notice: it differs by the finer and
more depressed pubescence ; by the hair on the breast being scarcely longer (even in the
male) than that on the abdomen, and by the pygidium being coarsely punctured with
a smooth middle space; in the present species the punctures are scattered, gradually
less numerous towards the tip.

One female from Georgia and another Missouri. Of the same size, form and sculp-
ture as the preceding, but differing not only by the color of the pubscence, but by its
texture ; the hair is short erect and brownish yellow; it is uniform on the thorax, but
on the elytra many longer hairs are intermixed, which on looking obliquely back-
wards, are seen to be arranged chiefly in three vitte, although there are some scattered
ones especially externally: the margin is fringed as in the preceding with long hair.
The sides of the abdomen under the elytra are slightly pruinose; the punctures
of the pygidium are larger and more distant than in L. ilicis. The legs are ferru-
ginous.

One male found at New York, and kindly given me by Mr. Guex. This species
has the form and sculpture of the preceding, but the pubescence is entirely uniform,
and the margin of the elytra is not fringed with long hair. The pygidium is moder-

the suture, three discoidal ones, and a marginal fringe. The pygidium is glabrous and
sparsely punctured. ‘The club of the antennze of the male is as long as the stem, the
middle of the abdomen is flattened, and the inner posterior spur is fixed.

GROUP X.

This group contains species having the characters of those of the two last, except
that the antenne have only nine joints (the seventh being obliterated;) the third,
fourth and fifth are equal in length, and connate ; the sixth is slightly produced inter-
nally. The tooth of the ungues varies according to the species.

One species is sparsely pilose, others have a few hairs on the front, while the
rest are glabrous: the thorax is never narrowed at the base.

One female, Georgia. Allied by characters to L. villifrons, but the form is more
convex, the punctures of the thorax are more distant, and those of the elytra less fine.
Body oblong ovate convex, bright yellowish brown inclining to reddish, darker on the
head and thorax. Head strongly and thickly punctured, sparsely pilose, with a slight
fovea at the middle of the front; clypeus emarginate finely margined. ‘Thorax one-
half wider than the head, convex, rounded on the sides, which are almost entire and
but sparsely ciliate; disc covered unequally with tolerably large sparse punctures,
leaving an indistinct smooth anterior space each side. Elytra slightly dilated behind,
convex, tolerably strongly punctured, with the sutural costa narrow elevated, and the
others completely wanting. Propygidium distinctly, not densely punctured ; pygidium

One female from Georgia. Of the size and proportions of L. fusca but more oblong
and convex, dark brown, very shining. Head strongly punctured, with a medial
abbreviated furrow; clypeus densely punctured, emarginate, with the margin reflexed.
Thorax nearly twice as wide as the head, more than twice as wide as long,

tured, punctures somewhat sparse. Elytra tolerably strongly punctured, slightly

rugous, with the sutural costa narrow and elevated; the discoidal ones may be traced,

and the submarginal one is very distinct, and somewhat elevated behind the middle.

Pygidium of the female conical, not very prominent at tip, smooth, with a few large

punctures at base. Pectus clothed thinly with short hair. Abdomen sparsely strongly

punctured at the sides and apex; penultimate segment slightly impressed transversely
each side; last segment deeply emarginate and ciliate at tip.

Care must be taken not to confound this species with L. glaberrima above described ;
the female of the latter has almost precisely the same form, color and sculpture, itis how-
ever not so convex ; the punctures of the clypeus are as distant as those of the head,
and the pygidium is closely punctured and not conical; the antennze are 10-jointed,
though by the consolidation of the articulations this fact is to be recognized by there
being two nodiform joints next the club; and finally the last point of the maxillary
palpi are externally impressed.

Texas, at New Braunfels, collected by Mr. Lindheimer. Body oblong, slightly
ovate, convex; above of a brownish red, with a grayish lustre on the elytra. Head
densely, thorax finely punctured, clothed not very densely with long soft erect yellow
hair; the thorax is short, and is not narrower at the base than at the middle. The
elytra are finely punctured, not costate, but with the sutural ridge broader and _ less
elevated than in the others; the surface is thinly clothed with short yellowish hair,
with longer hairs intermixed especially towards the base ; the margin is fringed: the
pygidium is moderately punctured: the breast is covered with tolerably long dense
hair.

In the male the club of the antenne is as long as the stem and the abdomen has a
scarcely perceptible anal impression: the spurs of the posterior tibiee are free in both
Sexes.

a. In one male specimen of a more cylindrical form there is a bifurcating oblique
elevated line each side of the penultimate ventral segment, but in the other specimens
I cannot perceive any vestige of such ornament. Subsequent collections may show
the propriety of regarding it as a separate species, for the sutural ridge is more strong-
ly marked, and somewhat narrower. I would hesitate at present to give it as distinct,
as no other difference in sculpture can be perceived.

Group XIII.

Consists of pruinose species, glabrous above, having 10-jointed antennz, and not
emarginate penultimate ventral segment. The head is comparatively large and the
clypeus is strongly margined, hardly sinuate in front. The mandibles project strongly ;
the last joint of the maxillary palpi is slightly oval, not impressed. The thorax is
rounded on the sides, not narrowed at the base. The breast is tolerably densely
clothed with long hairs; the tarsi are long and the ungues are toothed near the base.

In the males the club of the antenne is nearly as long as the stem; the penultimate

Kansas, near the Rocky Mountains. Agrees with the preceding in sculpture, but
is smaller and somewhat more robust, the surface is less pruinose, the punctures of
the elytra support hairs so much smaller that they are hardly visible, and the sub-
marginal costa can hardly be seen. The sexual characters are precisely as in the
preceding.

More full series may show the propriety of regarding this as a race of the preceding
species, but at present it seems sufficiently distinct to.entitle it to a separate name.

Group XIV..

I have placed in this group a single species having the appearance of those of the
next group, but differing by the more robust form, and by the mandibles being visible at
the tip. The head is small and hairy, the clypeus deeply concave and rounded ; the
last joint of the maxillary palpi is hardly oval, and not impressed; the mandibles
are visible and tolerably prominent. The antennz are 10-jointed. The thorax is
hairy and not narrowed at the base. The last ventral segment is very short, as in
the two preceding groups, and the penultimate of the male is not impressed. The

Mexican Boundary survey. The club of the antennz is nearly twice as long as the
stem; the abdomen is without impression ; the spurs of the posterior tibic are free,
long, flattened and obtuse.

Group XV. (D).

Contains some of the smallest species of the genus; they are of an oblong elongate
form, with the upper surface, at least of the thorax and base of the elytra, pilose with
long hairs. The head is small, the clypeus concave, broadly margined, and rounded.
The tips of the mandibles are not visible in a state of repose; the last joint of the
maxillary palpi is slightly oval and has an impression on the outer face. The thorax
is slightly narrowed at the base. The last segment of the abdomen is short, though
not so very short as in the groups XII, XIII, and XIV. The spurs of the posterior
tibie of both sexes are free, long flattened and obtuse, though slender. On account
of the small size of the mandibles the first species of the group was considered as a
distinct genus Trichesthes by Erichson,. but Lacordaire, considering it as established
upon insufficient grounds, has properly as I think, suppressed it. Burmeister retains
it in his work on Lamellicornia, but with an addition of species which renders it
unrecognizable.

GYNNIS Lec. ©

In this genus I have placed a single small elongate species, differing from species
of Group IV of Lachnosterna by the obliquity of the inner posterior spur of the male
and by the impression of the last joint of the maxillary palpi. The head is moder-
ate in size, with strong frontal suture, the clypeus is deep, rounded and strongly mar-
gined: the antennee are 9-jointed, with the third and fourth joints longer than the
following: the last joint of the maxillary palpi is oval and has a slight lateral im-
pression externally: the mandibles are moderately prominent, the labrum is very
short and broad, directed backwards and very slightly concave, not by any means
bilobed as in the other genera of Rhizotrogi known to me. The ligula is almost
truncate in front, and the mentum is broadly concave; the last joint of the labial
palpi is oval. The legs are slender, the middle tibize with two, the posterior tibize
with one transverse crest of spines: the tarsi are elongate, and the claws are hardly
perceptibly toothed near the middle. The inner spur of the posterior tibise of the
male is fixed, and slightly oblique, so as to form an inferior emargination, the outer
one is free, slender and acute. The last ventral segment of the abdomen is moderately
large, slightly impressed.

One specimen found at Philadelphia was given me by Mr. Schafhirt.

The club of the antennae of the male is longer than the stem; the abdomen is
longitudinally slightly impressed, and the last joint is faintly but broadly foveate, and
the fovea does not attain the anterior margin; the tibize are described above.

By the discovery of new species I have been compelled to modify the description
of this genus, until at last nothing distinct remains to separate it from Lachnosterna.
In one species the serration of the ungues disappears almost entirely, only a slight
trace near the base being left. There is however a peculiar appearance which renders
the genus easy of recognition, and notwithstanding the remarkable specific and sexual
characters, would make any further subdivision of the species here placed under it
eminently unnatural.

separate genus, but the preceding species is intermediate in the last mentioned
peculiarity, and the former is altogether a sexual mark. ‘The sixth ventral segment
is large, and projects downwards; it is smooth and flat on its anterior surface, strong-
ly punctured and hairy on the posterior surface, which is convex, and nearly hori-
zontal; the line where the two surfaces meet is armed at the middle with two large
sharp teeth.

4. DIPLOTAXES.

This group established by Kirby, but first defined as a sub-group by Lacordaire,
contains species of small size, forming the transition from the groups with transverse
not prominent anterior costz, to those with the cox conical. The thorax is almost
always furnished with an apical membranous margin, a character not known to me
in any other group except Dichelonyche, which differ by the chelate ungues. Bur-
meister’s group of Schizonyche should probably enter here, as they differ only by the
ereater depth of the emargination of the labrum, and the less breadth of the ligula:
the former is indeed not free from variation in our species of Diplotaxis. It has not
escaped the attentive eye of Lacordaire that the ventral sutures are distinct in this
group, not effaced at the middle as in Rhizotrogi; but he mentions that exceptions in
this respect are found in Empecta: as that genus has no apical margin of membrane
on the thorax, I am in doubt whether it might not be more naturally placed in
Rhizotrogi.

A character not noted by previous authors, which seems to distinguish this group,
is the entire coalescence, without perceptible suture between the 5th ventral segment
and the propygidium ; I know of no other group in which this takes place, and taken
in conjunction with the small pygidium, the disappearance of the sixth ventral segment,
the distinctness of the ventral sutures, and the prominence of the anterior coxe, it
would seem to render this as distinctly limited as the other groups here recognized.

Our genera may be thus distinguished :—

One specimen found with the preceding. This species is by its sculpture related to
D. punctata, but the thorax is more coarsely punctured, and the costz of the
elytra are marked with a very strong row of punctures, which with the punctures
between the geminate rows are furnished with short but stout suberect hairs: the
punctures of the thorax and those near the frontal suture also emit hairs. The la-
brum is more deeply emarginate than in the other species, but the under part of the
claws is as long as the upper, the thorax has a narrow apical membrane, and all the

other characters are of this genus.

Georgia, two specimens. Differs from all others known to me by the ovate body,
the sparsely punctured head, and bidentate tibiz. The punctures between the suture
and the first dorsal costze are confused, those between the other two costz and the
first are less so, but still somewhat confused. ‘The punctures of the under surface
are larger and more abundant than usual: the propygidium is more prominent than
in the other species and is marked near the apex with a tolerably strong transverse

raised line.

The following species cannot be refered to its proper division, from the loss of the
head.

A dead specimen found at Vallecitas, San Diego County, California. Resembles
in its proportions D. angularis, and probably belongs to Div. IV., but differs greatly
in the sculpture of the elytra; the punctures of the first interstice are confused, those
of the other intervals between the coste, are represented by rows of punctures equal
in size to those of the regular rows but more distant; the coste are without punc-
tures. The terminal tooth of the anterior tibize as usual is long, the others are
almost obsolete : the lower part of the ungues is acute, and hardly shorter than the
upper; the posterior tibiz have more long hairs than in D. angularis.

One specimen, Fort. Yuma, Colorado River, California. This insect has the appear-
ance of a large Aphodius. The spaces of the elytra which represent the cost are
marked each with a row of small punctures. The under surface is very coarsely
punctured, and the punctures have short yellowish hairs. The pygidium is very
coarsely and the propygidium densely punctured, the latter is transversely elevated,
or rather broadly sulcate near the apex. The posterior tibie at the outer apical
angle are armed with three longer spines.

One specimen found by Dr. Thos. H. Webb in the valley of the Gila. This species
repeats the form of the fifth division, as the next does the second of the genuine
Diplotaxes. The mandibles are more prominent than usual, and bent downwards,
so that the ligula is covered by them. The pygidium and propygidium are very
coarsely punctured, and the latter has the usual transverse impression near the apex.
The apical fovese of the thorax are half way between the middle line and the angles,

the others are near the side, and at the greatest breadth.

from a ventral view hardly converge towards the base. The punctures between the
smooth lines of the elytra are confused, and somewhat rugous. The pygidium is
coarsely punctured and sparsely hairy; the propygidium is more densely punctured,
with the usual transverse impression.

One specimen, Kansas. Closely allied to the preceding, and precisely similar to it
in sculpture: the body is, however, not at all ovate, and the sides of the thorax are
more regularly and less suddenly rounded. These two species by the strong apical
marginal line of the thorax form a passage to the Rhizotrogi ; many of which they re-
semble in the form of the claws.

The head is hardly one-fourth narrower than the thorax, which differs remarkably
in form from that of any other species in the group, in not being conspicuously
narrowed in front. The under surface is coarsely punctured, more sparsely at the
middle of the metosternum ; the punctures support very short hairs.

5. SERIC A.

This group is readily known from all the others by the labrum being connate with
the clypeus, and very frequently indistinct ; in addition, the anterior coxe are conical
and prominent ; the abdominal segments are hardly connate, the penultimate dorsal and
ventral are separated by a straight suture, and the stigma is concealed in the anterior
angle. ;

The genus Serica M’Leay, the only one found in our territory, belongs to the divi-
sion of genuine Serice, having the posterior coxe dilated, and the ligula corneous and
connate with the mentum ; it may be thus separated into two groups: |

Southern States, Kansas, and as far south-west as Chihuahua. This species is more
slender in its form and is readily known from the others by the longer thorax and
total absence of erect hairs. Herbst in the description insists so strongly on the
“ flachliegenden Harchen,” that I have considered the species as known to him. The
characters given by Burmeister are relative, except that he states the anus to be tes-
taceous. It is so in all the specimens before me, but sometimes too the whole abdo-
men is of the same color. The abdomen of the female is large and- convex, with a
few bristles at the middle of the four anterior joints; that of the male is more com-
pressed, with numerous spine-like bristles arranged in rows each side of the middle.

7. DICHELONYCH &.

A small group, confined to the American continent, and of which the well known
genus from which it derives its name is the sole representative within our territory.
As a group, it is distinguished from foreign groups among the Melolonthide with
prominent conical anterior coxe, free labrum and abdominal segments, by the ligula
being connate with the mentum, the labrum large, vertical and deeply emarginate,
and by the sternum not being protuberant. ‘The thorax as in Diplotaxes has a nar-
row apical membranous margin. With regard to the position of the group, Lacordaire
forms with it the passage from the Sericoides to the Macrodactylides ; from the latter
of which it differs according to his classification by the fifth ventral segment not being
larger than the others. I find, however, in Macrodactylus that the difference in size
of the segments is byno means obvious, and I am inclined, therefore, with Burmeister
to rank the present as a sub-group of Macrodactylide, verging indeed by the freely
moving and prehensile claws to the Hoplide.

the club of the antenne being as long as the funiculus.

Pennsylvania, New York, Massachusetts, Michigan and Lake Superior. Very
abundant whenever found. Varies in color, the head and thorax being sometimes
almost rufous ; the elytra are uniformly bronzed, the suture and a narrow margin only
being pale. The lateral angles of the thorax are rounded, and the scutel is pubescent.
The legs are yellow; the tarsi and posterior tibiz are more or less tinged with black-
ish. I have placed a query to the synonym of Kirby, as his var. C. (which he sup-
poses may be different from the type) evidently belongs to the next species, which
from want of attention to the form of the thorax (a character that has been omitted

by previous authors) may be readily confounded with the present.

Eagle Harbor, Lake Superior, only two females were found. Differs from the pre-

Middle States and Lake Superior. When the hair of the thorax has been removed,
as is sometimes the case, this species may be known by the very dense, but not fine
punctures of the thorax, the base of which is wider than the apex, and the-sides angu-
lated at the middle. There appears to be a variation in the form of the basal angles,
sometimes they are subacute and moderately prominent, sometimes rectangular, and
sometimes obtuse ; they are never very acute and prominent as in D. elongata. It is
possible that by comparing specimens from different localities several closely allied
species here confounded together may be separated.

One female from Maryland has the posterior angles more prominent, and the elytra
of a dull brownish bronze color. The thorax appears more coarsely punctured, but
it is unsafe to propose a new species upon this single specimen.

Steilacoom, Washington Territory, Dr. Suckley. Allied closely to the preceding,
but the thorax is less densely and more strongly punctured, less suddenly angulated
on the sides, and less narrowed behind, and the reflexed margin of the clypeus is very

narrow.

North side of Lake Superior. Burmeister places this as synonymous with D. linearis ;
my specimens are however clearly different, not only by the dark colored antenne,
but by the more strongly margined clypeus, and by the more coarsely and less densely
punctured thorax; on each side of the disc anteriorly, near the lateral fovea is an
indistinct space which is less punctured; the sides are less angulated, and not at all
sinuate behind. The specimens were found floating in the lake, and had lost nearly
all the pubescence; from the appearance of what remains on the side of the thorax,
I believe that the hair was coarse and probably dense as in D. linearis. Kirby does
not mention this character, but it may have been lost in the alcohol in which the
specimens were preserved; the hair of the under surface, being better protected, has

been preserved in both his specimens and mine.

clypeus truncate, but the angles though rectangular are less marked.

8. LASIOPODES.

In this group I have comprised two genera, containing species of small size, living
upon flowers. Although differing remarkably in appearance and characters, not less
from each other than from all other genera of the tribe known to me, I have been
induced to associate them together on account of the following characters, which they
have in common.

The anterior coxse are large, conical and protuberant ; the abdomen is very small,
-and the sutures between the anterior segments are nearly effaced; the last segment
is conical, free, and larger than usual. The parapleurse are narrow. ‘The claws are
diverging, with a very short bisetose onychium; the posterior tibia: are armed with
two spurs, but the anterior tibiz have no spur.

Lastopus Lec.

Clypeus rotundatus, valde concavus, ad apicem subemarginatus ; mentum parvum lineare; pedes postici
incrassati ; ungues simplices elongati.

Body oval, elongate convex, fringed at the sides and beneath, and on the legs with
very long hairs. Head small, eyes large, hardly emarginate, clypeus rounded, deeply
concave, slightly emarginate at tip, separated from the head by a deep transverse
concave line. Mouth small, labrum and mandibles invisible ; mentum small, narrow,
not larger than the base of the maxilla. Palpi slender. Antennz 9-jointed ; first
and second joints thick, hairy ; four following small ; club three jointed, small. Thorax
rounded on the sides, convex, narrower in front. EHlytra elongate, convex, partly
covering the pygidium. Legs strong, hairy; anterior tibize subtridentate; middle
tibize conical, with a crown of spines externally at the middle, and two terminal

spurs; posterior thighs very large, posterior tibie like the middle ones, but much
thicker. Tarsi twice as long as the tibia, slender, with verticillate hairs at the articu-
lations ; last joint with two long terminal hairs above; ungues long, slender, diverging
onychium hardly visible, bisetose.

I have given to this genus an unpublished name proposed by Dejean for Aclopus
Erichson, to which genus this seems to bear a remarkable resemblance in form. The
labrum and mandibles are however entirely invisible. I regret that I cannot give
the position of the abdominal stigmata, but conclude that they must be very much as
in the next genus.

Ringgold Barracks, Texas. We owe this most interesting addition to our fauna to
the scientific industry of Mr. H. Haldeman. The genus will be readily recognized
by the narrow oval body, fringed with long hairs, and by the long hairs of the legs,
and the thickness of the posterior femora and tibize.

Oncervus Lec.

Clypeus duplex ; mentum trapezoideum barbatum ; pedes postici incrassati ; ungues fissi.

The only species of this genus known to me is the smallest of the tribe that I have
seen, and presents such a curious assemblage of characters that I am at a loss which
to select. The form might be compared to a Hoplia, oblong and more narrowed in
front ; the. body is shining, sparsely hairy, especially beneath. The head is narrow
with convex prominent eyes, the clypeus prolonged, flattened, parallel on the sides,
rounded slightly at the apex and incised each side, with a deep transverse concave
suture between the incisions; the frontal suture is straight and deep, running between
the antenne. which are short; the first and second joints are thick and hairy; then
follow four small joints, and then a small three-jointed club concave outwards; the
mentum is large, flat, trapezoidal, wider in front, with long scattered hairs; the bases
of the maxille are long, slender and prominent each side of the mentum ; the maxil-
lary palpi are slender, penultimate joint small, last joint elongate, slightly oval; labial
with the last joint longer than the preceding, slightly oval. Thorax wider than the

_ head, rounded on the sides, and gradually narrowed in front, Llytra a little wider

than the base of the thorax, oblong, slightly flattened on the disc, with the sutural
stria fine. Pygidium slightly exposed. Legs strong, hairy, anterior tibize subbiden-
tate; middle tibize conical, moderately thick, with a crown of short spines at the

_middle externally, and two apical spurs. Posterior thighs very large, tibie thick

conical, with a crown of spines externally about one-third from the tip, and two apical

spurs. ‘Tarsi slender, longer than the tibize, with verticellate hairs; ungues diverging,
armed with a tooth so long that they appear cleft; onychium short bisetose. |

Found at Vallecitas, San Diego Co., California in April, on flowers of a composite
plant. I can find no sexual characters in the specimens collected. By examination
I find the abdominal stigmata situated in the dorsal inflexed portion of the ventral
segments; the last pair I cannot detect, since the margins of the ventral segments are
thin and reflexed above the dorsal surface, so as to produce a concave surface, in which
the posterior pairs are concealed.

9. HOPLLAL.

©

This division is known among those having prominent conical anterior cox by
the ventral segments being connate, the sixth indistinct or even invisible; by the
large parapleure ; the tibize without terminal spurs or at most with a single very small
one, and by the ungues being chelate (7. e. capable of being folded against the last
joint of the tarsi,) not divergent, unequal and without any onychium.

In this division, though not in any American form, is found a modification of ligula
not seen or only exceptionally in any of the preceding tribes; the ligula is membra-
nous, and not connate with the mentum : by this character, found in Pachycnemis
and allied genera, the passage to the following group is most naturally made.

The only genus found in our country, and in fact the only one found outside of
Southern Africa, is

One specimen found in Pennsylvania was kindly sent me by Dr. Melsheimer. Of
the size and appearance of H. convexula, but more elongate, with the sides of the
thorax less rounded. The thorax is hardly distinctly narrowed in front, except in
consequence of the gradual curvature of the sides, which thus do not appear oblique,
nor at all angulated. The elytra are at base wider than the base of the thorax, and
somewhat retuse near the apex. The middle claws are wanting, the outer one of the
anterior tarsi is one third shorter than the inner one.

uniformly clothed with them. Such a specimen would appear to be described by
Burmeister, and such a one is now before me; the upper tooth of the anterior tibiz is

Melolontha mucorea Germ. Ins. Nov. 129.

Southern States. Readily known by the more elongate and parallel form. The
posterior tarsi are broken, so that I do not know whether the claw is simple or bifid.
I have excluded H. helvola, as asynonym, since the description mentions linear
scales on the elytra; it seems to me rather to be the variety of H. trifasciatawith

almost uniformly colored elytra, and this view accords with the measurements given.

H. monticola, Mels. Proc. Acad. Nat. Se. Phila. 2, 141, I have failed to identify. The dimen-
sions given are 32 lines by 13, which are the proportions of H. mucorea. From notes sent me by Dr.
Melsheimer, it would seem to differ from both that species and H. modesta. The color is brownish testa-
ceous, the head and thorax are darker, the latter clothed with short rufous hairs and sprinkled towards the
sides with whitish scales, ‘the sides are somewhat dilated beyond the middle, slightly incurved posteriorly, sub-
rectilinear from its widest portion to the tip; elytra hardly wider at the base than the base of thorax’, more
than twice as long as the thorax, clothed with short rufous hairs, two obsolete longitudinal raised lines near
the middle, pygidium clothed like the elytra, venter covered with small whitish scaly hairs. ‘ Anterior
tibie bidentate ; inner middle claw less than one half the size of the outer one: posterior claw entire.’
Pennsylvania, in Adams County.

Should the last character be erroneous, it might be referred to the light colored
specimens mentioned under H. modesta.

10. GLAPHYRI.

A group placed by Erichson among the laparostict Scarabaeidae, but in which, as
Burmeister has shewn, the position of the abdominal stigmata ceases to be of value
as a primary character. As a group of Melolonthidex, this may be readily recognized
by the labrum being at the end of the clypeus, and in the same plane ; by the projecting
mandibles, the wide parapleurze, and the not connate six-jointed abdomen. The
ungues are slender, equal and diverging. . The only genus found in the United States
is Lichnanthe, which differs from Amphicoma chiefly by the deeply emarginate
labrum.

Remarks.—There are two specimens only of this fine species among the shells from
Mr. Haines, procured through Dr. House from Siam. I dedicate it to Mr. Haines
with great pleasure. In outline it is close to U. superbus, (nobis,) but is more rotund.
It is more shallow in the cavity, much thicker in the anterior portion, and in the
teeth they differ much. The cardinal teeth of U. swperbus are long and lamellar,
while in Hainesianus they are short, thick and conical. The nacre is not so pearly in
the latter. In outline and form of the teeth it approaches Unio Paranensis, (nobis,)
also, but the lateral teeth are not so he and the upper section of the double tooth

falls much shorter than the lower section. The beaks of both specimens are eroded,
but there are marks observable along the anterior slope, which display a single row
of an unusual form, but too indistinct to describe clearly.

fluent; dorsal cicatrices deeply marked in the centre of the cavity of the beak; pal-
leal cicatrix deeply impressed ; cavity of the shell somewhat deep: cavity of the beaks

Remarks.—There is a very close resemblance between this and Housei, herein
described, and they may possibly prove to be merely strong varieties when complete
suites are obtained. There are some sixteen specimens of the two before me, and they
can be separated by the crenulated cardinal teeth of Myersianus, which species is also
larger and more ponderous. The oldest specimens have the teeth flatter and more
crenulate. In some of the specimens the cicatrix of the superior anterior tractor
muscle is separate from the other anterior cicatrix, and deeply impressed. Unfor-
tunately not one of the specimens has a perfect wing before or behind, but there re-
mains evidence of their being somewhat elevated. ‘This is one of the fine shells
procured by Mr. Haines from Bangkok, through the kindness of Mr. John K. Myers,
of New York, after whom I name it. :

Shell with two wings, connate before and behind, smooth, triangular, compressed,

rather long and concealed; epidermis greenish brown with two lines in the posterior

of growth distant and indistinct; cardinal teeth long, lamellar, oblique and double in
both valves, but more defined in the right; lateral teeth long, very lamellar, slightly
curved and joined to the cardinal tooth; anterior cicatrices distinct, the larger one
having a deep sinus on the superior part ; posterior cicatrices very indistinctly marked,
confluent; dorsal cicatrices well marked in the cavity of the beaks; cavity of the
shell very shallow; cavity of the beaks very shallow and obtusely angular; nacre
delicately salmon colored and iridescent.

Remarks.—This belongs to a natural group of symphynote species of which U.
delphinus may be considered the type. It is, however, not so wide, nor has it so high
a wing posteriorly. It differs also in the teeth, the cardinal teeth being more lamel-
lar and divided into two or more parts, while those in the delphinus are flattened and
erenulate or granose. The lamellar teeth of delphinus are nearly straight, or entirely
so, while those of Howsei are more or less curved. The specimens were all more or
less injured, and particularly in the wings.

I owe this, with many other species from Siam, to the kindness of Mr. W. A.
Haines, who obtained them from Dr. House, now a resident of the city of Bangkok,
and to the latter gentleman I dedicate this fine species with pleasure.

yellow and not so much inflated towards the beaks. It also resembles U. corrugatus,
Retz., but is not corrugate, nor is it quite so transverse. It differs also in color.
The tips of the beaks being eroded in this specimen, I am unable to say if there be
any undulations there in perfect individuais.

femarks.—This species has a close resemblance to U. superbus (nobis) from New
Holland. It may be distinguished from it by the gravidus being more inflated, by its
yellow epidermis and bluish white nacre. The swperbus is a thicker shell, and the
teeth are less lamellar and the cardinal teeth are rather shorter. All I have seen are
delicately salmon colored, while the ten or twelve specimens of gravidus before me
are allwhite. The greater transverse diameter is much nearer the centre of the shell,
and the outline approaches more to the rotund. The three rays on the posterior slope
are very distinct and beautiful in the young specimens. The lunule is in several of
the specimens remarkably large. The cardinal teeth in right valve are disposed to
curve upwards.

Mr. Haines received this species, with many interesting ones, from Dr. House, of
Bangkok, Siam.

specimens of this species. It is not remarkable for any peculiar characters. In outline
it closely approaches H. ce@ruleus, (nobis,) but it differs in not having a bluish epider-
mis, in being more transverse, and in not possessing the fine undulations of the beaks
and the posterior slope. Neither of the specimens are entirely perfect at the tips of

Remarks.—There were about a dozen of this species submitted to my examination
by Mr. Haines, differing very much from each other. Some of them are tuberculate
nearly over the whole surface, while others are almost entirely without tubercles. In
this it agrees with U. corrugatus, Retz, and U. Tavoyensis, Gould. In outline it closely
approaches U. Javanus, (nobis,) but is a rougher shell and the folds on the posterior
slope are coarser. In some specimens the tubercles about the beaks resemble those
of U. Murchisonianus, (nobis.)

Remarks.—In outline and general appearance this interesting species resembles the
young of Unio alatus, Say. It may at once be recognised to be different by the numerous
small folds—which are visible in the interior as well as the exterior—as well also by
the peculiar number and place of the lateral and cardinal teeth. It would naturally
follow, as a plicate shell, U. Micklinianus, (nobis.) The most remarkable feature
in this species is the possession of three lateral teeth in the left valve. In the eight
specimens before me the three teeth are recognised. In all of them the upper division
is smaller than the two lower ones, and the upper one of the two of the right valve is
also always smaller. The cardinal teeth are remarkable for being double in the right
_and single in the left valve. Some of the specimeus are enlarged over the umbonial
slope, immediately behind which there is a slight emargination at base. The enlarge-
ment is owing probably to sexual difference.

from Bagdad. But it is a larger species, not of so fine a polish, and the cardinal teeth
are longer and more lamellar. In outline it also has some affinity to U. rusticus,
herein described, but it differs in being more oblique and being without tubercles.

folds. In the crispatus the folds cover the whole surface. In our shell they are
smaller and extend over the upper part only of the valve, and down the posterior
slope. In the teeth they are quite different; those of the crispatus being thicker and
the cardinal teeth being shorter and double in both valves. The folds are small and
numerous, and may be seen on the inside of the valves in the region of the beaks and
the posterior slope. ‘The size of hwmilis is about that of U. acutissimus, (nobis,) but is
not so angular on the posterior margin, and the folds are smaller and more numerous.
It differs also in color, the acutissimus being more yellow.

ftemarks.—This species belongs to a group in which may be included gratiosus,
Phili., erispatus, Gould, humilis and nucleus herein described. In outline it very much
assimilates to crispatus, but it differs very much in having few folds, in being highly
polished, less angular at the posterior margin, and more rounded and inflated on the
posterior slope. ‘The younger specimens have a strong resemblance to humilis, but

general form and emargination of the base, give it very much the appearance of a

Remarks.—There were two specimens and an odd valve only of this species among
the Siamese shells brought by Dr. House. In general form and characteristics, it is
exceedingly like U. Cailliauduw, Fer., from Kgypt, and might at first sight be taken for
that species. It is, however, entirely different in the cardinal teeth as to form, size
and condition. Our shell has lamellar teeth, double in the right and single in the
left valve, while the Cailliaudu has short, thick teeth, double in both valves. Both
my specimens of Cailliaudiw have minute rays over the whole disk, while sagittarius
seems to be entirely without them. It must be remarked, however, that the speci-
mens are by no means perfect. Neither of them have the beaks perfect enough to
ascertain if they have been plicate. In outline this species has also some affinity to
U. Ingallsianus, (nobis,) but it is much more transverse and more cylindrical.

Shell folded, transverse, compressed in the middle, very inequilateral, angular be-

acutely angular over the middle, on the umbonial slope enlarging from the beaks to
the posterior margin, where they are nearly parallel; ligament short and thin ; epider-
mis yellow, the raised folds being always green, transversely and minutely striate ;

Reemarks.—This very beautiful Siamese little species was first sent to me by Dr. Ingalls,
of Greenwich, N. Y. Several specimens of different sizes have since been put into my
possession by Mr. Haines, to whom I am indebted for so many new species from this
part of Asia. On receipt of Dr. Ingalls’ specimens I had some doubts of their being a
variety only of Dr. Gould’s crispatus, but this doubt was dispelled on receipt of Mr.
Haines’ specimens. It belongs to that group of which gratiosus, Phili., may be con-
sidered the type. It certainly is nearest allied to crispatus, but may be distinguished
by its being smaller, more transverse, having larger folds, and these thickly covering
the whole disk, except on the last growth of old individuals ; also in being compressed
over the middle, and emarginate at base and in the duplex form of the lateral teeth.
The crispatus is disposed to be yellowish in the cavity of the beaks, while scobinatus
is pearly white. In outline scobinatus approaches phaselus herein described, which is
rather smaller, and is a polished shell with few folds. They both have the duplex

lateral tooth in both valves. Like nwclews herein described the transverse close strize
are very remarkable, and in both, the folds are beautifully developed on the inside
In some specimens the strize are nearly obliterated.

Remarks.—Two opposed valves of nearly the same size were all which Mr. Haines
received among his Siamese shells. In form and general character this species is
nearly allied to U. imornatus herein described. It differs in being a little more
transverse, and in being thicker and smaller. It resembles in outline U. c@ruleus,
(nobis,) but has no bluish tint in the epidermis, and is entirely without rays, and is
smaller. It is a very small species, not larger than a middle sized U. parvus, Barnes.
It might be mistaken fora young U. Ingallsianus, (nobis,) but that shell is more oblique
and smoother, and differs in the color of the posterior slope.

Remarks.—This species was procured by Mr. HE. Verreaux while in South Africa,
and given to me while in Paris, in 1853. Subsequently Mr. Haines submitted
specimens to me from the same habitat. The anterior muscular cicatrices present an
unusual character in the three, being remarkably distinct. The undulations of the
beaks are beautifully distinct, numerous and regular, and are delicately arranged also
on the posterior slope as well as over a large portion of the beaks. In outline and
general! character it is allied to U. Batavus, Lam., and more particularly to that variety
named U. Carynthiacus by Ziegler. In outline and general form Africanus approaches
Verreawianus, herein described, but it differs entirely in size and in the surface, being
smooth and polished, while Verreawianus belongs to the sulcate division, and is
usually twice the size; they therefore cannot be confounded. It approaches also to
U. Caffer, Krauss, but differs much from the figure given by him, (Sudafrik Moll.,
p- 18.) It much more resembles a specimen given to me by the late Prof. E. Forbes,
from South Africa under that name.

Femarks.—I owe the possession of several specimens of this interesting species to
Mr. Verreaux, naturalist, of Paris, whose researches for many years in South Africa,
&c., has added so much to various branches of natural history. It belongs to that
group which I have called swlcate, from the transverse furrows which exist in the
substance of the exterior of the shell. It is not so sulcate as Scamnatus, Morelet,
nor is it so much compressed. In outline and general form, it is nearly allied to U.
confertus, (nobis,) but is not so ventricose as that species, nor is it so angular behind.
It cannot be confounded with U. Caffer, Krauss, as that species is much smaller, more
compressed, the form more elliptical, the teeth more tuberculose and the nacre purple.

I dedicate the species to that persevering traveller, Mr. Edward Verreaux.

very delicate small undulations, and furnished with two indistinct lines from the beak
to posterior margin ; ligament rather short and thin; epidermis greenish yellow, with
obscure green rays; umbonial slope rounded; cardinal teeth rather long, compressed

dorsal cicatrices placed within the cavity of the beaks and on the under side of the
posterior portion of the cardinal tooth ; cavity of the shell rather deep; cavity of the
beaks shallow and subangular; nacre slightly salmon colored and iridescent.

Remarks.—Several specimens of this shell are before me. Two of them are odd,
young valves. The specimen figured has been in my possession some years, but being
very closely allied to U. gratiosus, Phili., I feared it might prove a variety only of
that species. The young specimens and other adults since received, satisfy me that
they are distinct. The specimens of gratiosus which I have in my cabinent are
much less transverse and much smaller. They are precisely the same in outline and
folds with Dr. Philippi’s figure, (Conchylien, v. 1, t. 1, f. 5.) The Shurilefianus is
more cylindrical and the basal margin is disposed to be emarginate. The folds are
beautifully disposed over the upper part of the disk up to the tip of the beaks. They
are remarkably minute, and so divergent and re-entering, as to make zigzag lines. In
outline and size the Shurtlefianus is very near to cceruleus, (nobis,) also from India,
but it may easily be distinguished from that species by being devoid of that bluish
color, by the posterior margin being less angular, by the beaks being more medial and
the nacre being salmon colored. The teeth are also less lamellar and the folds more
numerous. It differs from crispatus, Gould, in having coarser folds, in color of nacre,
as well as in having the teeth more lamellar, and the posterior margin being less acute.

I have dedicated this species to Dr. Shurtieff, to whose kindness I owe specimens of
several ages.

Remarks.—A single specimen of this species only was submitted to me by Dr. Budd,
but it differs so much from any described shell I am acquainted with that I have not
hesitated to giveit a name. In general aspect it resembles U. ellipticus, (Diplodon
ellipticum, Spix), but it is not transverse, seems to be without folds and has more
marked transverse strie; the lateral teeth are more curved and the epidermis is more
highly polished. The beaks of the specimen above described are eroded, and more
perfect ones may be found to have undulations at the tips.

dorsal cicatrices consist of a long row from the smaller anterior cicatrix across the
interior cavity to the under part of the lateral tooth; cavity of the shell rather shal-
low ; cavity of the beaks small, subangular ; nacre purple and iridescent.
Remarks.—But a single specimen of this shell is before me; interesting from the
fact, as an Australian species, it should so closely resemble an American one, as, at
first sight, it might be considered to be merely a variety. It has very nearly the
exact outline of Hopetonensis, (nobis,) from Georgia, and is nearly of the same color
in the epidermis. It differs in having transverse furrows nearly over the whole disk,
which in the Georgian are but slightly developed. It has smaller teeth, and in the
left valve the cardinal tooth is single, in the right scarcely bifid. The color of the
nacre of the specimen before me is of a darker purple than any of the Georgian species
which I have seen. ‘The color of the nacre may differ in other specimens, as it does
in the Hopetonensis, which is sometimes white and sometimes slightly salmon colored.
The beaks of the specimen of Shuttleworthw before me are eroded, and therefore it is
impossible to say if they be undulate; but I suspect that in perfect specimens they
will be found to be so, as on the posterior slope very indistinct undulations may be
perceived, decussating an obscure furrow running from the beaks to the posterior
margin. If in other specimens these folds are found more numerous and more pro-
nounced, then we ought to remove the species from the furrowed to the plicate group.
The carina is so much elevated that it might almost be considered to belong to the

alate division.

Remarks.—I1 owe the possession of this beautiful species to my friend Prof. Dtinker,
of Cassel, to whom I dedicate it. Subsequently I procured a specimen from Mr.
Verreaux, of Paris. When Prof. Diinker presented me with the specimen, he was
under the impression that it was D’Orbigny’s rhuocoica, but that is quite a distinct
species, being less transverse, of a lighter brown and with smaller and shorter coste at
the beaks. The costee of Diinkerianus extend, in the two specimens before me, somuch
longer over the disk, and particularly near the umbonial slope, that it must be entitled
to be placed among the folded species.

Remarks.—This species is very remarkable for its diminutive size. There were only
two specimens submitted to me by Mr. Haines, and I believe they are all he received.
They are nearly of the same size ; and if they be of normal dimensions, the species is
certainly the smallest I am acquainted with. It is nearest to U. crispatus, Gould, in
general appearance, being covered over with nearly the same kind of folds, which are
green like crispatus. In outline, however, it differs very much as well as in size, not
being more than one-third the breadth. The umbonial slope is also much more angular.
It might be suspected that it had been mistaken for a young crispatus, but on
comparison with a young crispatus before me, I find it flatter, less robust, with
smaller folds and more yellow. The minute strie over the disk are close and
lamellate, and are of a brownish color. The folds over the whole disk are strongly
marked, are green and disposed to run into angles, while the intermediate spaces are
yellowish. On the inside the folds are distinctly visible.

Remarks.—The specimen above described is probably quite a young one, and I have
great doubt of its really being a native of Arabia. Among many fine shells brought
by Captain Brown, from nearly all parts of the world where he carried on his
commercial affairs, were many rare and fine specimens from the rivers of South
America. This specimen was marked in one valve “ Mocha ;” in the other, “ Red
Sea ;”
brought there by trading vessels from South America, having some of the characters

so that he most probably purchased it in Arabia; and still it may have been

of that habitat, particularly the diverging costz on the beaks; which character so
peculiarly belongs to most of the species of that quarter of the globe. It seems to
be more nearly allied to U. Paranensis, (nobis,) than to any species Iam acquainted
with, but it is not so rotund, nor is it so much inflated along the umbonial slope. The
coste of the beaks are smaller, and the epidermis is green and not brown as in
Paranensis. It is also somewhat like U. Burroughianus, (nobis,) from South
America, but is not so transverse as that species, and is not so high on the umbonial
slope. On the posterior slope there are two distinct rays from the beak to the margin,
one being yellow and the other dark green. 1 name this in honor of the late Captain
Brown, of Beverly, Mass., to whose kindness I owe the possession of the specimen.

Remarks.—A. young shell, apparently not one-fourth grown, was sent tome some time
since by Mr. C. M. Wheatley, who procured it from the Rio Negro, at the distance of
1200 miles from the mouth of the Amazon. After comparing this young individual
carefully with all my South American specimens, and with the descriptions of Spix
and Von Martius, as well as those of D’Orbigny, I am satisfied that it can only be as-
similated to a specimen which that distinguished traveller and zoologist, Mr. D’Orbigny,
sent to me with several other specimens as U. lacteolus, (nobis,) (delodontus, Lam.) I
have always doubted that specimen being the same species with those which it' accom-
panied, and now connect it with this young specimen under the name of my friend
Mr. Wheatley. Iam not prepared to say, when we shall find mature specimens from the
Rio Negro, that it may not prove distinct from the shell from Monte Video. The form
of the former is more triangular, and it varies in being flesh colored. The species above
described may be distinguished from delodontus, Lam., by being less transverse, and
having longer and larger diverging ribs at the beaks, which in both specimens before
me converge a short distance below the tip of the beak so as to form re-entering
angles. It differs from Burroughianus, (nobis,) and Paranensis, (nobis,) in being less
transverse than the former, and being less rotund than the latter. It is also less
rotund than membranaceus, Maton.

Remarks—Among a number of interesting land and fresh water shells which I
procured from Mr. E. Verreaux, in Paris, was a single small specimen of this
species, evidently quite young. I should suppose about one-fourth grown. ‘The above
diagnosis therefore may be found to be, in many respects incorrect, when mature
individuals shall be examined. ‘The oblong outline of this shell is remarkably regular.
The costz of the beaks are smaller on the posterior and anterior slopes and several of
them form re-entering angles on the posterior slope and on thesides. This species has
some affinity to Charruanus, D’Orb., but differs in being more oblong, in having
smaller costee on the beaks, and in having the posterior slope more elevated.

Remarks.—I owe to the kindness of Prof. Nuttall, two specimens of this pretty
little species, which he gave me on my last visit to England, in 1853. In outline it
approaches U. olivaceus, (nobis,) from Calcutta, but is a little more angular on the
posterior margin. It is by no means so thin in the substance of the shell, and differs
in the teeth, they being in the Nuttal/ianus thicker and less lamellar. The color is
very different, the olwaceus being pale blue, while both the specimens before me of
‘Nuttallianus are salmon colored within and olive without, and with transverse bands.
There is a group of Uniones in India, which are disposed to be bluish, and the ceruleus,
(nobis,) may be considered decidedly the type. The Nuttallianus has an epidermis
of rather a bluish green olive, and the nacreous matter deposited in the interior of the
beaks of both specimens is decidedly blue. The tips of the beaks being eroded in both
specimens, it is impossible to say if there be undulations, but the blue hue of the
nacre in the beaks is very observable there. The outline of U. Keraudreni, Hydoux, is
nearly the same with this species; but they are evidently distinct. I dedicate
this pretty little species to my old friend Prof. Nuttall, who has done so much to
elucidate the natural history and botany of the United States.

Remarks.—W hen I described Unio Tampicoensis, m 1835, (Trans. Am. Phil. Soc.
Vol. 6, p. 24,) I was in possession of the above described shell also by the kindness
of the late Dr. Burrough. In the remarks, I then mentioned that in the younger
specimens the epidermis was of a yellow brown, and that indistinct rays might be
observed. Having had access to other specimens all of the same size, and particularly
a fine one from Mr. Anthony, of Cincinnati, who also obtained it from Dr. Burrough’s
collection, I am satisfied that, although nearly allied to Yampicoensis, it must be
considered to be distinct. It differs in being not quite so oblique, in the beaks not
being so prominent, the epidermis not being blackish but of a fine dark brown. It
also has obsolete rays, while the other seems to have none, and the nacre is disposed
to be more rose color and purple. All the specimens before me are more or less thus
colored, while Zampicoensis, is usually white with pinkish lateral teeth.

There is rather a remarkable feature in the three specimens before me, about the
centre of the cavity of the interior of the disk, all of which are granulose with small
irregular pearls.

Remarks.—Among the Uniones of Lake Nicaragua, this species, taken by Dr. New-
comb, has not, I believe, heretofore been observed. It is a very remarkable species, as
well from its outline, as from its singular corrugate and furrowed disk. It differs from
all the species which I know, in this character. We have some species of Naiades
with wrinkled epidermis,* but not so much so as this, nor are they accompanied by
furrows like this. It differs from U. aratus, (nobis,) also from Lake Nicaragua, in
being round and in having wrinkles as well as furrows. ‘T'wo of the three specimens
before me are adult, and in these there is apparently, in the left valve, a disposition
to form a third division of tooth. The largest of the three specimens is probably a
female, as there is an enlargement at the posterior basal margin, which indicates that
sex. It causes the outline to present a subtriangular form, which is not the case with
the other two.

T owe to Dr. Newcomb the possession of this beautiful little species, as well as many
other fresh water and land shells, and with pleasure dedicate it to him, who has proved
so industrious and successful an investigator in this branch of Zoology.

Remarks.—Among the shells from Takrong River, was a single small Unio which

cardinal teeth, being single and double on the reversed sides, so common with the
species from the East of Asia. The tips of the beaks being eroded, the character of the
undulations cannot be given, but it is evident from those which may be yet seen on
the posterior slope of this specimen, that they must be numerous, regular and close.
In outline and in color it is near to U. crocatus, (nobis,) from Georgia ; but is a much
smaller species and rather more transverse.

than the first, and more inflated than the latter, and the posterior slope is nearly
raised into a wing. It is not obovate like purpuratus. Young and perfect specimens
will probably be found to be quite alate. The purple color of the specimen before me
is not quite so dark as the alatus and purpuratus. In my specimen there is in
each valve an imperfect cicatrix, situated nearly in the centre of the interior of the
disk, and such may be the case with Dr. Budd’s. If this should be found to be
developed in the species, it will resemble in this character the trapezoides, (nobis,) the
only Unio I know to possess the additional muscle (ventral muscle). The beaks of
the specimen before me are too much eroded to give the character of the tips, but
they are evidently slightly undulate.

It differs from Yampicoensis, (nobis,) to which it is allied, by being a larger species,
being higher in the carina of the posterior slope, in having a brown radiated epidermis
instead of a blackish rayless one, and in the purple color of the nacre.

316 LEA’S DECRIPTIONS OF EXOTIC GENERA

that of Unio cylindricus, Say, but it is a much thinner shell and entirely without
tubercles, which are so remarkable on the umbonial slope of that species. It is closely
allied to U. Fopew, (nobis,) but is not so much compressed, is different in color, more
cyclindrical as well being furnished with granules. The epidermis of Poeyanusis very
remarkable. It is very thin and firmly attached to the calcareous matter, and
when examined witha good lens very minute granules may be seen over the surface ;
at the anterior part the strie are imbricate. The two specimens differ in color.

or outlet, and not surrounded by marshy ground, the distance from the Cauca River
being 5 miles. This pond is within half a mile of Cartago.”

AND SPECIES OF THE FAMILY UNIONIDA. of

The above described species is more like Anodon radiatus, Spix, (Test. Fluv. Bras.
pl. 23, fig. 1,) than any other South American species. It is about the same size,
but in outline it differs by being more oblong and less elliptical. It differs also in
not being rayed. It is very nearly of the same outline with Anodonta fluviatilis of
our rivers, but it cannot be confounded with that species, as it has the peculiarly formed
fosset at the posterior end of the ligament, which is so remarkable in the South
‘American Anodontg. The singular crimpled rays in the epidermis are very remarkable,
but it may not be a permanent character of the species. It is to be regretted that a
single specimen only has come under my view. I owe this one to the kindness of the
Rey. Mr. Holton, who mentions in his travels that they were in abundance near
Cartago, and to him I dedicate it.

Subgenus PLAGIODON.*

Testa zquivalvis, inzequilatera, obliqué trigona, valdé inflata ; dentibus cardinalibus crenulatis, compressis,

Proc. Acad. Nat. Sci. Vol. 8, p. 79.

Shell equivalve, inequilateral, obliquely trigonal, very much inflated; cardinal
teeth crenulate, compressed, transverse, short, double in each valve ; no lateral teeth ;
muscular impression composite before.

This subgenus is proposed for a fluviatile shell, which is nearer to Monocondylea,
DOrbigny, than to Margaritana, Schumacher, and may be considered properly, as so
interposed as a link to connect them. It has the epidermis of Monocondylea, being
of a dull cloth-like texture, and not polished and smooth, like the Unio generally is.
The point in which it chiefly differs is the peculiar structure of the teeth. As in
Monocondylea there is no lateral tooth, the part of the dorsal margin where that
exists in the Unio forming a plate, is here simply a line, forming a margin over a deep
cavity, on which line is placed a thin delicate ligament. The cardinal tooth is large,
but unlike the Margaritana it is transversely compressed, and the upper division is
longer and begins immediately over the lower one, between it and the beak. In
Monocondyleca the cardinal teeth consist of one smooth rather large lobe or callus, in
each valve, passing each other, and fitting into a corresponding depression in the
opposed valve. If we may judge from a single specimen of Playiodon I should
conclude that the substance of the valves was never so thick as that of Monocondylea.
It is much more inflated, the three diameters being nearly the same, that through
the axis being rather smaller. Being a very light shell, and having so peculiar a
form, it cannot be very locomotive. From its rotundity, and having the beaks nearly

* maaypios, transversus and édsc, dens.

318 LEA’S DESCRIPTIONS OF EXOTIC GENERA

terminal, incurved and recurved, it at once reminds one of Jsocardia cor, Lam., or
rather of Jsocardia Moltkiana, Lam., having a notable angle on the umbonial slope
and presenting a perfectly cordate form on the anterior view. The posterior cicatrices
are confluent like Monocondyleea, and but slightly impressed. ‘The inferior anterior
cicatrices are deeply impressed, and so closely united as scarcely to be distinguishable.
The superior anterior cicatrix is placed on the inner side of the cardinal tooth, and
higher up than on that of the Monocondylea. The dorsal cicatrices are placed so far
into the deep cavity of beaks, as to be but partly and faintly visible.

The absence of the soft parts of this shell is greatly to be regretted. From the
clobular form, the epidermis and the teeth, we would be led to expect to find some-
thing different in the structure of some of its organs, as it is very likely to be in its
habits, from Monocondylea or Unio.

Judging from avery imperfect left valve of Monocondylea Guarayana, D’Orb., all
that I have seen, I should not be surprised if it would prove to belong properly to
this genus. Certainly the form of tooth is different from that of the other Monocondylea.
It is, however, very much compressed, and is much thicker in the substance of the
shell. /

The epidermis of Plagiodon is of that texture and color, which reminds one of
some of the estuary genera, Cyrena, Clathrodon, &., but its pearly nacre and form
of teeth place it among the Naiades without doubt.

angular ; posterior slope very broad and flattened, with two obscure impressed lines ;
anterior slope widely cordate and flattened, with a large, slightly impressed furrow ;
anterior lunule broad with several transverse, impressed parallel lines ; cardinal teeth
crenulate, compressed, transverse, short, the upper division longer, double in each
valve; the two anterior inferior cicatrices deeply impressed and confluent, the superior
one placed on the inner side of the tooth; posterior cicatrices confluent; dorsal
ceicatrices placed within the cavity of the beaks, and but partly visible; pallial cicatrix
very slightly impressed; cavity of the shell very deep and rounded; cavity of the
beak very deep and subangular; nacre white and very iridescent.

Remarks.—I procured this very remarkable shell in Paris, from Mr, HE. Verreaux,
whose researches and collections in South America, Africa, &c., have been so extensive.
It has the general aspect of a very much inflated Monocondylea Paraguayana, D’Orb.,
but the form of the teeth is totally different, and the shell thinner and more vesicular.
The anterior slope is almost as cordate as kocardia Moltkiana, Lam., the beaks
presenting an incurved form somewhat like that shell. The angle on the umbonial
slope is also somewhat similar and it has a like flattened side. The anterior lanule
is very wide, and immediately under the point of the beaks there are three transverse
impressed lines, very unusual in the Naiades, which may not be constant even in this

species.

without rays; lines of growth numerous and distinct ; ligament very long and slender ;
umbonial slope slightly angular; cardinal teeth rather large, erect, crenulate and
double in both valves; lateral teeth very long, rather compressed, curved and
enlarged at the posterior end; anterior cicatrices deeply impressed and all three
distinct ; the posterior cicatrices distinct, the inferior one being large and inflected,
the superior one being small and very much removed from the great one; dorsal
cicatrices forming a long row across the cavity of the beaks; pallial cicatrix rather
deeply impressed ; cavity of the shell deep in the left valve and shallow in the right ;
cavity of the beaks very shallow ; nacre silvery white.

Remarks.—This very remarkable species of the TZriquetra, of Klein, (Hyria, of
Lamarck,) was first placed in my hand by Tho. R. Ingalls, M. D., to whose kindness
I am indebted for many new species from rare and distant habitats. This specimen
consists only of the right valve, and was among shells received by Mr. Asa Fitch,
of Salem, New York, in a box from China, with Anodonta magnifica, Dipsas plicatus,
and other well known Chinese species.

This is certainly the most remarkable form of any of the genus TJriquetra yet
observed. Its remarkable transverseness at once removes it from subviridis, Klein,
(avicularis, Lam.) In outline it approaches Spatha celestis, (nobis.) It is the
first time that this genus has been observed out’ of South America, where it has
heretofore been considered to be peculiar. The great posterior cicatrix is of an
unusual form, being irregularly elongate and but slightly oblique to the tooth above
it. The minor superior cicatrix is unusually distant from the posterior terminal point
of the lateral tooth, where it is usually placed in all the family Naiades. In this
shell itis removed quite half an inch from the point, and placed rather below the
tooth itself and nearly perpendicular to the end of the great cicatrix, which here is
obliquely directed towards the anterior instead of the posterior margin. The three
anterior cicatrices are remarkably distinct, the superior one being placed on the end
of the cardinal tooth. There is an appearance of a row of cicatrices under the dorsal
line, anterior to the great cicatriz, which is situated anteriorly to the cardinal tooth.
The whole interior of the valve is covered with beautiful minute papille. The beak
is so much eroded that it is impossible to say if the tips in a perfect state be undu-
late or not.

In the short diagnosis which I made of this new species of Triquetra, (Proceedings,
vol. vill. p. 79,) I had but a single valve, which had the appearance of being twisted
like Arca tortuosa, Lin. This extraordinary form, which had never been suspected
to exist in any member of the family Naiades, excited great interest with the
Zoologists who saw it; but it was still a matter of doubt whether the curve, although
exceedingly regular and presenting no appearance of constraint or injury, might not
be abnormal, This doubt has now, however, been put entirely at rest, for the curve

AND SPECIES OF THE FAMILY UNIONIDA. 321

of the two specimens now before me, are so precisely the same, that when the odd
right valve is placed against the left of the other, they fit perfectly, proving that the
curve is a mathematical law belonging to the species. The specimen now figured
belongs to H. Cuming, Esq., of London, and is nearly perfect. My single valve was
recognized by Mr. Cuming at once, on his recent visit to this country, to be the same
as that in his cabinet, and he promptly and liberally offered to place this unique
specimen in my hands, for a more perfect description and figure than could be given
of the single immature valve I already had. Mr. Cuming’s specimen is nearly six
inches along the dorsal line to the angle of the posterior margin, and this line deflects
quite two inches in the course of the six inches from a straight line, and it is so
twisted that the basal margin at the posterior end turns up to be on a plane with the
dorsal line at the beaks. ‘This remarkable curve causes the long lateral teeth to have
a curve of double curvature. The greatest distance from the dorsal to the basal
margin is one inch and three-tenths. The greatest diameter is nine-tenths of an inch,
which gives it a sub-cylindrical form, and it is not unlike a twisted banana, (Musa
sapientum.) This perfect specimen presents the superior portion of the valves covered
with small, regular tubercles, which was not suspected in the original, somewhat
imperfect single valve, there being on it only a few irregular undulate markings. Mr.
Cuming’s specimen settles the doubt as to habitat. He received his from Shanghai,
and therefore Mr. Fitch and Dr. Ingalls, to whom I owe the possession of the single
valve, were right in assigning it to China. Doubts arose of this from the fact that,
heretofore, Zriquetra has been considered to be confined to South America. I propose
the name should be changed from that I originally gave it, (7. lanceolata,) as
inappropriate to the complete mature shell, to that of contorta, which is very descriptive,
and can never be mistaken. .

ART. XX.— Observations on a yroup of Cretaceous Fossil Shells, found in Vippah
County, Miss., with descriptions of fifty-six new species.

By T. A. Conran.

The Cretaceous strata of Mississippi have long since been observed and partially
noticed by geologists, and the lamented Professor Tuomey has described a number of
their fossil contents. I now introduce quite a distinct group of shells, which are
imbedded in a different matrix compared with the prevalent cretaceous marls, green
sand and limestones. The discovery of these beautiful organic remains is due to the
indefatigable exertions of Dr. W. Spillman, of Columbus, who has forwarded a
collection of specimens more or less perfect, consisting of nearly sixty species, all of
which appear to be unpublished except Scaphites Conradi. The appearance of these
shells is like that of eocene species which have merely lost their animal matter, and
in this respect are very unlike the condition of similar genera in the contiguous rocks
of the same era. The fossils are imbedded in a sandy marl of a dark gray color, the
principal constituents of which are fine scales of mica and grains of quartz mixed with
fragments of small shells; and though some of the very thin species are distorted, the
stronger retain their original shapes and are generally very perfect. Species of
CRASSATELLA, NucuLA and Muretrix have the valves united as in life, as well as a
few of the extremely thin InoczrAmt, though the latter have been more or less distorted
by pressure. The numerical proportion of species of Cephala and Acephala is nearly
equal. The external sculpture of all is as sharply defined as in existing species.
Besides ScApHitEs and Bacutirss, there is only one shell in the collection which
resembles a species of the green sand or limestone, and itis quite distinct. The rare genus
Putyintrss is herein for the first time introduced as an American form. The analogous
species, as well as that of GERVILLIA, occurs in the Baculite limestone of France and
Normandy, which I believe is referred by D’Orbigny to his Senonien Stage, the same
in which he includes the Cretaceous fossils of North America.

It is interesting to find bivalves of so remote an era in sufficient preservation to
exhibit generic characters as clearly defined as they are in living shells. In this
condition are the hinges of Grrvyinn1a, Putyinites, Crenomes and Carpium. ‘There
are also specimens of BacuLites and Scapuites which exhibit the interior divested of
all extraneous matter, and delight the eye with exquisite curves of the foliated septa,
whilst the shells glow with brilliant iridescent tints.

524 CONRAD’S DESCRIPTIONS OF

This beautiful series of cretaceous forms seems to be very limited in geographical
distribution, so far as our present knowledge extends. It is probably unknown as
yet beyond the limits of Tippah County, which borders on Tennessee. No account
has been given of such a group by the State Geologists of Tennessee or Alabama.

Dr. Spillman informs me, “ The fossils you have now under examination were found

in the bluffs of Owl creek, three miles north of the town of Ripley,” and he concurs
in opinion with me that they might properly be named the “ Ripley group.” He also
remarks that Ammonites placenta occurs in it with the shell preserved, and that in
connection with the Ripley group, or in the same locality, are “ Hxogyra costata,
*Gryphea mutabilis, Ostrea plumosa, Natica petrosa, Nautilus Dekayi, dc., with the
shell more or less preserved, in/an argillo-caleareous marl,” but none of these species are
contained in his collection sent me from Tippah County.

Professor Harper, in his report for 1857, describes some of the Teenies of the above
group near Ripley, and names many of the genera of its contained fossils.

It would perhaps be convenient to designate these strata Upper Cretaceous, in
contradistinction to the limestones and marls beneath, which are palzeontologically so
distinct.

ACHPHALA.
PHOLADOMYA, Sowerby.
PHOLADOMYA TIPPANA. Pl. 34, fig. 9. Acutely subovate, very thin, profoundly
ventricose, with numerous radii, curved and dichotomous on the anal side.
An imperfect specimen, with a portion of the shell, has been restored to an ap-
proximate outline in the figure. The sculpture is in sufficient preservation to charac-
terise the species.

PERIPLOMA, Schum.

PERIPLOMA APPLICATA. Oblong-oval, equilateral, compressed, thin and fragile;
right valve convex-depressed ; left valve flattened or slightly concave, with an oblique
anterior carinated line; valves smooth in the middle, roughened with rugose concen-
tric lines posteriorly ; anterior end truncated or obtusely rounded, nearly direct; basal
margin contracted in the middle. :

Length 14 inches.

~SILIQUARIA, Schum.

SILIQUARIA BIPLICATA. PI. 34, fig. 17. Thin, convex, with two radiating folds or
depressions anteriorly ; basal line slightly contracted or incurved ; anterior side short,

extremity truncated ; posterior margin obtusely rounded, posterior side concentrically
lineated ; valves somewhat contracted obliquely from beak to base.

An elegant species, remarkable by the slightly undulated anterior. Substance
of shell thin and fragile, yet one perfect valve is in Dr. Spillman’s collection.

Family SOLENIDZE.
LEGUMEN, Conrad.

Shell equivalve, very inequilateral, flattened ; hinge with two very slender teeth in
the right valve under the beak, and one posterior very oblique prominent lamelliform
tooth.

This genus is perhaps most nearly related to CuLtTEeLtus, Schum. It can
readily be distinguished by external characters; its flat valves, straight and more
produced anterior side, &c.

LrGuMEN ELLIPTICUS. PI. 34, fig. 19. Oblong, compressed, very inequilateral, very
thin; valves flattened or contracted obliquely from beak to base, concentrically
lineated; beak not prominent above the hinge line, apex acute; ends regularly and
nearly equally rounded; posterior extremity situated much more nearly on a line
with the hinge than the ventral margin.

One right valve only is before me. The cardinal teeth are well preserved; two
slender and very prominent, and one lamelliform, posterior, oblique.

LEGUMEN APPRESSUS. Hlongated, much compressed; beak not prominent above the
hinge line ; hinge and base nearly parallel; posterior extremity acutely rounded, and
nearly on a line with the hinge; valves finely striated with close regular impressed
lines.

Smaller and proportionally longer than the preceding. It came to hand too late
to be figured.

DOSINIA, Scopolt.

DosiniA DENSATA. Pl. 34, fig. 13. Subtriangular or suborbicular, inequilateral,
rather thick in substance; length rather more than the height; concentric striz
obsolete, except towards the apex; posterior side prominently wrinkled towards the
margin ; posterior margin obliquely truncated ; beaks not prominent.

In old specimens the anterior margin is truncated, and rounded in the young,
which are more orbicular. The cardinal plate is broad, the teeth very prominent
and the anterior tooth of the left valve very thick inferiorly.

This is the second species of DosinzA found in the American Cretaceous strata.
The first occurs in the older division.

'MERETRIX, Lam.

MERETRIX TIPPANA. PI. 34, fig. 18. Subtriangular, obsoletely striated concen-
trically; anterior side slightly compressed, with an ascending basal margin, extremity
rather acutely rounded, distant from the apex; base a little prominent in the middle
subtruncated on either side; posterior end but slightly more obtuse than the anterior
beaks prominent.

PAPYRIDEA, Swains.

PAPYRIDEA BELLA. Suboval, very thin and fragile, ventricose ; radii angular, promi-
nent, about 30 in number, towards the extremities minutely tuberculated ; ribs obso-
lete near the buccal end; basal margin somewhat salient opposite the umbo; trun-
cated posteriorly ; anal end truncated, nearly direct.

This species is proportionally shorter than the elegantulwm or protextwm. The
largest specimen in Dr. Spillman’s collection is not so large as those species usually
are. Received since the plates were finished.

There are two other species of this genus in the inferior Cretaceous marls. Papyridea
(Cardiwm) elegantulum, Roemer, and P. (Cardiwm) proteatum, Con.

CARDIUM, Lin.

1. Carprum tippanum. PI. 34, fig. 8 6. Cordate, profoundly ventricose, rather thick ;
umbo and summit prominent; ribs flattened, little prominent, tricarinate, armed with -
prominent erect spines; in the intercostal space is a row of minute tubercles, except
on the posterior side, where a prominent intercostal line appears.

A mere fragment, so well marked, however, that the description and figure will
characterize the species. 7

2. CARDIUM RIPLEYENSE. A small cordate species, with minute equal radii, between
each of which is a series of comparatively long hair-like spines.

Subgenus LAXVICARDIUM, Swainson.

3. Carprum SprLiMANI. Pl. 34, fig.3. Oblong or profoundly elevated, inequilateral,
profoundly ventricose ; umbo and summit elevated; beaks nearly contiguous; surface
with distant irregular grooves on the anterior side, and 3 to 5 radiating slightly
impressed furrows on the umbonal slope.

Length 2g inch. Height 42 inch.

A large and remarkably elevated species with a very thick hinge and profound
teeth. The surface is smooth and only ribbed about the umbonal slope, and on the
posterior side of the umbo where in one specimen are about 18 radii; those behind —
the umbonal slope fine and indistinct without the aid ofa glass. Named in honor of
Dr. W. Spillman.

OPIS, Defrance.

1. Opts BicARINATA. A small orbiculato-trapezoidal, ventricose species, smooth ;
umbonal slope and posterior submargin carinated, postal area concave.

2. OPIS BELLA. ‘Triangular, convex, polished, with regular and elegant concentric
lines, or minute flat ribs, separated by linear grooves; posterior side cuneiform.

About the size of the following species of Tellina, but a little longer and more
pointed posteriorly.

TELLINA.

TELLINA RIPLEYANA. Ovato-triangular, equilateral, compressed, polished ; concen-
trically lineated towards anterior extremity. Length nearly 4 inch; height nearly
$ inch.

This and the two preceding species of Opis were discovered after the plates were
finished. They will be figured in a future number of this Journal.

CRASSATELLA, Lam.

CRASATELLA RIPLEYANA. Pl. 35, fig. 3. Triangular, very inequilateral, thick,
flexuous or plicate posteriorly ; umbonal slope angulated, subcarinated ; disk covered
with numerous irregular concentric furrows or coarse prominent lines; posterior side
cuneiform, extremity obtusely rounded ; margin above obliquely truncated; posterior
margin opposite the umbo angulated; inferiorly concave; margin densely crenu-
lated within.

This, from the number of specimens sent, I judge to be an abundant species, very
distinct from all others of this country which have hitherto been described. The
cardinal plate is very broad, and the teeth thick and prominent. Its state of
preservation is equal to that of any Tertiary bivalve.

NUCULA, Lam.

NUCULA PERCRASSA. PI. 35, fig.4. Triangular, very thick, ventricose, inequila-
teral, densely radiated with minute impressed lines; anterior end subnasute, margin
obliquely truncated; posterior side cuneiform, extremity slightly salient, rounded,
situated much above the line of the base; basal margin rounded, sometimes slightly
contracted anteriorly; within crenulated on the margin; submargin thickened ;
cicatrices deeply impressed ; cardinal teeth thick, fosset oblique.

This species appears to be abundant and in excellent preservation; one specimen
has the valves united. The interior is silvery; the pallial impression very distinct,
and. an irregular line of five small cicatrices runs over the upper part of the valves in
the direction of the shell’s length. The form of this NucuLAis very unlike any other
American species.

328 CONRAD’S DESCRIPTIONS OF

CIBOTA, Browne.—BYSSOARCA, Swainson.

CrsorA LINTEA. PI. 34, fig. 11. Rhomboidal, very inequilateral ; sides flattened or
slightly contracted, radii minute, close, reticulated, except on anal side, where the
radii are wider and smooth; hinge and basal margins parallel, the latter slightly
contracted; anal margin very obliquely truncated.

This genus has been named NaAvicuta by Blainville, and Byssoarca by Swainson.

CUCULLAA, Lam.

CUCULLHA CAPAX. PI. 35, fig. 2. Obliquely triangular, inequilateral, profoundly
capacious, elevated ; posterior slope flattened, very broad, forming nearly a right angle
with the terminal umbonal slope which is abruptly rounded ; valves slightly contracted ;
umbo profoundly prominent, beaks distant; surface reticulated with fine lines, the
radii in pairs, most conspicuous posteriorly, largest on the left valve.

2. CucULLHA TIPPANA. PI. 35 fig. 1. Short trapezoidal, inequivalved, inequila-
teral, ventricose ; radiating lines numerous, reticulated, most conspicuous on the left
valve; umbo prominent; beaks rather distant; cardinal area profound, with three
angular impressed lines; umbonal slope acutely rounded.

In the specimen figured, the margin of the larger valve is thick, abruptly grooved
within, in which groove the margin of the opposite valve is inserted. Allied to C.
Shumardi, Meek.

DREISSENA, Van Beneden.

DREISSENA TIPPANA. PI. 34, fig. 14. Falcate, with distinct lines of growth; front
excavated, the margin acutely angular; the dorsal and posterior margin form a
regular curve ; base rounded ; beaks acute.

This shell somwhat resembles Dreissena polymorpha. The hinge is not accessible
in the only specimen in the collection. The valves are united and are remarkably
perfect. The form is not unlike that of Mytilus falcatus, D’Orbigny.

PINNA, Lin.

PINNA LAQUEATA. A fragment—ventricose, with eleven prominent, slender ribs}
interstices concave.

GERVILLIA, Defrance.

GERVILLIA ENSIFoRMIS. PI. 34, fig. 10. Ensiform or falcate, profoundly compressed,
iridescent ; hinge with about twenty-seven radiating prominent teeth; cavity very
shallow, with an irregular surface, the upper margin angular; within pearly and
iridescent.

Two valves of this species are in Dr. Spillman’s collection, which are both broken

off as represented in the figures, but the remainder perfectly preserved, and the
hinge is as entire as that of a recent bivalve. It differs from G. solenoides, in having
an anterior wing with a truncated margin; in being much more compressed, and in
having an uninterrupted series of prominent cardinal teeth, &c.

CTENOIDES, Klein.—LIMA, Brug.

CTENOIDES ACUTILINEATA. PI. 34, fig. 2. Oblong, oblique, very thin ; posterior side
radiated with acute, prominent lines, thirteen to fifteen in number; anterior side with
minute, close, radiating lines ; surface concentrically wrinkled ; posterior margin sub-
rectilinear.

This somewhat resembles L. Wacoensis, Roemer, in outline, but it is less ventricose,
and has radiating lines, whilst the other is costate.

Klein founded this genus on the shell known as Lima glacialis, and the L. scabra is
the type of his genus Raputa.

INOCERAMUS, Parkinson.

1. INOcCERAMUS ARGENTEUS. PI. 34, fig. 16. Obliquely suboval, very thin, smooth,
inflated anteriorly; umbo prominent; summit elevated ; lines of growth towards the
posterior margin assume the form of squamose striz ; anterior side very short; mar-

gin obtusely rounded.

2. INOCERAMUS COSTELLATUS. PI. 34, fig.12. Obliquely subovate, ventricose ; radii
slightly prominent, rounded, close, disappearing posteriorly, obsolete towards the
anterior margin; concentric acute lines ornament the surface; anterior side very
short, obtuse; umbo and beak of larger valve very prominent.

This species is marked exteriorly like a PHoLapomya, but is inequivalve, with the
hinge of an InoczrAmus. ‘The specimen is distorted.

Species of this genus were figured by Klein in 1770, under the generic names of
SponpIoLitHos, Muscuites and PHoLADIS.

OSTREA, Lin.

OsTREA PECULIARIS. PI. 34, fig. 7. Oblong or elliptical, thin, ventricose along the
middle and depressed on the sides; surface with radiating wrinkles ; margins towards
the apex denticulated.

A thin and abundant species remarkable by the tuberculated or denticulated mar-
gins and elongated trilobe shape.

2. OSTREA CONFRAGOSA. PI. 34, fig. 4. Very irregular; rather thin ; lower valve
profoundly ventricose, with deep irregular cavities or depressions.
The lower valve only is known,.and is very unlike any other Cretaceous species in

the United States.

4, OSTREA DENTICULIFERA. Pl. 34, figs. 1 and 8. Irregular, moderately thick,
indented, but not plicated; upper valve flattened ; hinge area wide, with a transverse
ridge at, the base of the fosset; lower valve moderately capacious ; upper margins
denticulated ; muscular impressions large.

EXOGYRA, Say.

EXOGYRA INTERRUPTA, PI. 34, fig. 15. Adhering, thin ; lower valve with inter-
rupted radiating costae; upper valve entire, with a thickened margin.

A small species. The lower valves in all the specimens adhere to other shells and
nearly conceal the exterior character.

PULVINITKES, Defrance.

PULVINITES ARGENTEA. PI. 34, fig. 5. Transversely subovate, compressed ; per-
forated valve slightly concave; foramen oval, from its upper margin a channel
extends to the apex; substance of shell silvery, thin; cardinal plate broad, with
about thirteen radii or teeth ; the lower valve presents within the appearance of two
muscular impressions, the one above the other, the former striated.

The present species of this rare genus is allied to P. Adansonw, but differs from
the figures of that species in having a broader hinge plate, and much less curvature
of the posterior margin. It closely resembles an AnomiA exteriorly. P. Adansonii
characterises the Upper Cretaceous rocks of Hurope.

ANOMIA, Lin.

ANOMIA SELL&ForMIS. Pl. 34, fig. 6. Suborbicular, with a short fold anteriorly
towards the hinge line; posterior side with a profound plication.

Length # inch.

There is but one valve of this species in Dr. Spillman’s collection, and _per-
haps other specimens may exhibit a considerable variation from the saddle-shape
character.

GASTEROPODA.

STROMBUS, Lin.

Srrompus DENsATUS. PI. 35, fig. 14. Lip expanded, very thick; coste disap-
pearing on the middle of the volution; labrum suddenly thickened, with a groove
behind the raised margin; a calcareous deposit sometimes coats the whole shell, rising
into an oblique, thick, prominent ridge, the upper margin of which is on a line with
the apex.

APORRHAIS, Petiver.

APORRHAIS DECEMLIRATA. PI. 30, fig. 11. Spire elevated, acute; volutions ‘nine,
convex, longitudinally costate, and finely striated transversely ; ribs distant, promi-

nent, angular, acute, short on the back of the body volution, but extending in front
to a carinated line which borders the labrum ; transverse striz distinct at base ; labrum
extended into the rostrum above the middle, where it is angulated and subcarinated
and channelled within. :

. The beak is broken as well as the rostrum of the outer lip, but otherwise the only
specimen in the collection is very well preserved.

HARPAGO, Klein.—PTEROCERA, Lam.

HARPAGO TIPPANUS. PI. 35, fig. 25. A fragment, with smooth subangulated volu-
tions, a carinated line revolving at the base of each; rostrum of the labrum pro-
foundly extended, trilobate, the central and upper lobe profoundly carinated in the
middle; substance of the shell thin.

The labrum has evidently been extended above the apex, but only a slight trace
of it remains near the upper part of the spire. The specimen is evidently a young
or immature shell.

RIMELLA ? Agass.

RIMELLA CURVILIRATUS. PI. 35, fig. 9. Fusiform, ribbed longitudinally; ribs
somewhat curved, slightly sinuous, about twenty-three in number on the body volu-
tion; interstices transversely striated ; beak produced ?

CONUS, Lin.

Conus CANALIS. PI. 35, fig. 22. Spire prominent, volutions profoundly angular
in consequence of a deep channel revolving at the suture.

A very remarkable species, in its profoundly channelled suture presenting a strong
contrast to more modern fossil or recent cones.

DRILLIA, Gray.

1. Driniia NovemcostaTA. PI. 35, fig. 13. Subfusiform, spire elevated ; volutions
scalariform, having distant, wide, prominent, rounded slightly oblique costa, termi-
nating above at a crenulated line which borders the suture ; body volution with short,
_ very prominent, tuberculiform, thick ribs; revolving lines obsolete above, prominent
and alternated inferiorly.

2. DrILuiA? TIPPANA. PI. 36, fig. 5. Subfusiform, with thick, rounded, smooth,
longitudinal ribs on the body volution, each tuberculiform at the summit; ribs of the
spire tuberculiform at base, or interrupted in the middle; base with thick, prominent
revolving lines.

B32 CONRAD’S DESCRIPTIONS OF

TURRIS, Rumphiuws—PLEUROTOMA, Lam.

TURRIS RIPLEYANA. PI. 35, fig. 21 and 29? Elongated, slender; spire subequal
in length to body volution and beak; volutions ribbed longitudinally; ribs slight

which causes the appearance of a prominent line bordering the suture ; surface of shell
with revolving lines distinct on the body whorl and beak.

FUSUS, Klein.

FUSUS NOVEMLIRATUS. PI. 35, fig. 18. Elongated ; spire elevated, acute; volutions
seven ; longitudinally costate and transversely striated, ribs thick, prominent, rounded ;
suture margined by crenulated line; body volutions having about nine distant, very
large rounded costz which become obsolete about the middle of the volution ; inferiorly
marked with longitudinal lines or furrows ; beak slender, elongated, sinuous.

Subgenus AFER.

FUSUS BELLALIRATUS. PI. 30, fig. 17. Fusiform, spire prominent, acute; volutions
of spire seven, subscalariform ; tuberculated inferiorly and ornamented with revolving
lines ; body volution ribbed longitudinally, and having prominent transverse, robust
lines, which on the ribs assume a tubercular aspect ; beak elongated.

This shell is referred to a subgeneric division of which Fusus afer, Lam., may be
regarded as the type.

PYRIFUSUS, Conrad.
Pyriform ; columella broad, thick, flattened; body volution transversely oval.

PYRIFUSUS SUBDENSATUS. PI1.35, fig. 12. Subpyriform ; spire short, subscalariform,
volutions four ? longitudinally ribbed and spirally lineated, lines minute ; body whorl
wide, contracted above where there are longitudinal wrinkles and revolving lines ; below
are prominent ribs becoming obsolete about the middle, and prominent, revolving
lines over the whole surface below the shoulder.

FICUS, lew.

Ficus octotrratus. Pl. 35, fig. 6. Pyriform; spire conical ; costae of body volution
about eight in number, inclined to be square, distant; beak long and slender.

RAPA, Klein.

RAPA SUPRAPLICATA. PI. 35, fig.20. Pyriform ; spire depressed, volutions flattened
above ; summits ornamented with oblique, curved strie or grooves.

A very much broken specimen, but the fragment exhibits marked characters. It
is a very ventricose, smooth species, easily recognised by its flattened volutions and
curved lines.

Another less perfect specimen has been a much larger shell. This species bears
some resemblance to Voluta Lamberti, of the British Miocene. A young specimen
which is figured in outline has a very acute spire and minute revolving lines. The
columella being imperfect, the plaits have not been observed. The base is narrow,
produced and but slightly emarginate.

CHEMNITZIA, D’ Orbigny.

1. CHEMNITZIA INTERRUPTA. PI. 35, fig. 15. Spire prominent, scalariform, pro-
foundly costate longitudinally ; ribs interrupted below the suture by a deep furrow;
base with rather distant, revolving lines.

Columella and base imperfect; therefore this and the following shell are only pro-
visionally referred to CHEMNITZIA. :

2. CHEMNITZIA DISTANS. PI. 35, fig. 30. Short—subfusiform; spire prominent,
subscalariform ; volutions four, reticulated ; body volution with longitudinal, distant
ribs intersected by distant, prominent, revolving lines; columella profoundly curved
near the middle.

BACULITES, Lam.

BACULITES TIPPAENSIS. PI. 35, fig. 27. Acutely ovate, smooth, with profoundly
sinuous lines of growth, which rise on the sides, and curve downwards on the back
and front; shell splendidly iridescent ; back regularly rounded ; front slightly con-
tracted, or with depressed lines on the sub-margin.

This species can be readily distinguished from B. ovata, Say, by its acutely ovate
outline viewed in a tranverse section. The substance of the shell appears to be
in perfect preservation, beautifully iridescent, and the lines of growth run profoundly
oblique downwards to the front, which they cross in nearly straight lines. 7 Specimens
show the interior free from sand, with the foliated septa as perfect as when the
animal inhabitant was alive. In most specimens the front is obtusely carinated as
in the following species :

Bacuuites Sprimant. Pl. 35, fig. 24. Obtusely ovate; back flattened, front a
little raised or obtusely carinated; sides with distant, very thick, obtuse, curved,
remote ridges.

This is a beautiful species, even more highly iridescent than the preceding. ‘The
lines of growth are similar in form to those of the former species but more strongly
defined. The septa are too imperfectly exhibited to be defined by a drawing. The
substance of shell thin.

Dedicated to its discoverer Dr. W. Spillman.

SCAPHITES, Parkinson.

ScAPHITES IRIS. Pl. 35, fig. 23. Substance of shell very thin, highly irides-
cent; whole surface ornamented with pyramidal, distant tubercles, the inter-
vening spaces smooth; back rounded, with two rows of tubercles, another row
runs along the junction of the lateral with the dorsal margin; sides flattened.

A fragment of this beautiful species exhibits the extremely thin septa, in perfect
preservation and free from sand.

The form of the septa is very unlike that in S. Conradi, to which species I referred
it in my introductory remarks.

One adult specimen in Mus. Acad. Nat. Se. and two young (Bradybates poireti and
Triton nycthemerus) Dr. Wilson, Bonap. Collection.

Gen. Remarks.—Pleurodeles is related to the Tritons, but differs from them in its
large flattened head, its lengthened ribs, its long tail; the nares are more widely
separated than in the Tritons, the eyes more elliptical, the upper eyelid more de-
veloped, according to Micheelles. (Isis, 1830, p.191.) The parotids are also wanting
in the Tritons. P. Watli is found abundantly in cisterns near Cadiz, in the south of
Spain. We have in the collection of the Academy a single specimen, labelled Triton
nycthemerus, belonging to the Bonap. Collection, which is without doubt the young
of Pleurodeles Watli. Gray observes that it is, perhaps, the young of 7. marmoratus or
Triton cristatus, but the teeth are arranged as in Plewrodeles and not as in Triton,
and the tongue is alsothat of Plewrodeles, which is quite different from the tongue
of Triton:

Char.—Head round, occiput swollen, but the forehead depressed ; eyes small and
far apart; feet very short, toes small, but free throughout; body short, broad, the
the sides, as in Plewrodeles pierced by the ribs; tail shorter than the body, broad at
the base, roundish, towards the end more angular, differing remarkably from Pleuro-
deles, inasmuch as the latter has a very long sword-like tail; tongue small, rounded
like a firmly attached wart; no parotids; at the root of each foot two tolerably large
swellings. (Tschudi.)

Gen. Remarks.—Dumeril and Bibron are inclined to the opinion that this genus
may be only the young of Pleurodeles, coming from the same localities and possessing
many of its characters. “ We have inthe Bonaparte Collection, now belonging to
the Academy of Nat. Sciences, a single specimen marked Bradybates powretr, which is
evidently a young Pleurodeles, but the tail is longer than the body.” ‘Tschudi says
“Zahne ganz Plethodon,” but this is probably an error.

Gen. Remarks.—The coloration varies somewhat in different specimens. Of 25,
now before me, recently captured at Altoona, Pa., about 225 miles from Philadelphia,
by Dr. Wilson, Dr. Leidy and Mr. Conrad, I find that the young are much more
thickly spotted than the adults, which above present the confluent appearance of the
spots upon the sides; the abdomen and under part of the tail are bluish, sometimes
very minutely spotted with white, that part of the tail usually so; the upper part of
the head is generally free from spots, but a large one may often be seen upon the
skin; palms of soles of feet brick-dust red. Some of these specimens have a decidedly
granulated appearance, and are covered all over upon the back with very minute
white spots interspersed between the larger ones. The specimens from South Caro-
lina and Georgia present no differences in the coloration ; but among those of the
former is a marked variety noticed by Dr. Holbrook, entirely black above without
spots; chin and throat yellowish; abdomen dark brown, sometimes minutely white
spotted.

PLETHODON ERYTHRONOTUS.-—(Red-backed Salamander.)

Char.—Body cylindrical, with a broad red,* reddish brown or dusky yellow, or

Syn. Xiphonura Jeffersoniana, Tschudi.

Gen. Remarks.—This species and tagrinum would come under the genus Xiphonura,
Tschudi, but several other of our Ambystomata have compressed tails, viz. : laterale,
talpoideum, nebulosum ; and as the substitution of Xiphonura for Ambystoma leads to
confusion, we shall not adopt it, but prefer grouping them into Ambystomata with tails
much compressed, of which mgens may be considered the type, and those with tails
more or less rounded as venenosum and fasciatam ; Xiphonura Jeffersoniana, Tschudi,
is very probably Amby pare. mgens, but Salamandra Jeffersoniana, Green, is Plethodon
glutinosus.

Gen. hemarks.—There are four yellow spotted species, which are nearly allied, but
differ in the arrangement of the teeth, which will at once characterize each, viz. :
tigrinum in a straight transverse row ; /wridwm obtusely angular; episcopus much

less obtusely angular, and finally nehuloswm where the angle is acute.

TRITON CRISTATUS, Lawrenit.

Char.—“ Skin granulated, of a brownish green, often very deep upon the back and
sides; with large black spots, and small white salient spots, especially upon the sides;
under part of the body of an orange yellow, with black irregular spots; inferior
portion of the tail most often of a golden yellow, without spots; throat brown, with
some yellow marks, without large black spots, but small brown lines, and minutely
punctated with white. The male carries upon the back, especially at the period of
fecundation, a large brown membranous denticulated crest, which commences upon
the anterior part of the body, and is continued along the spine as far as the pelvis,
where it disappears; the tail, which is much compressed and large in the middle,
presents also, above and even beneath, a crest, the superior one of which is also

- slightly denticulated or festooned ; the crest of the female is not so much developed,

CADUCIBRANCHIATE URODELE BATRACHIANS. 359

and the underpart of the tail presents constantly a line or vitta of a yellow color,
more or less marked.”—Dum. et Bib.

Duméril and Bibron, who have had frequent opportunities of observing these
animals alive, describe three varieties—l. Very large, of the size of Salamandra
maculosa; blackish above, yellow spots under the jaw in the male, and under part of
tail in the female yellow, without spots. Var. 2. A little more than half the size of
the first. Brownish above, or greyish in the males, yellow color of abdomen less deep;
these varieties perhaps the affect of age. Var. 3. Triton carnifex; females of small
size; no dorsal crest, replaced for the most part by a yellow line prolonged upon the
tail. What distinguishes most, however, this variety is the pale yellow or whitish
color of the abdomen, with large black rounded spots; but rarely spotted in the
middle region. Length 4% inches long, (Fr.)

Habitat—Common in Europe, (abundant in N. of France,) found in the coldest
regions, (N. Africa, Schlegel.)

77 specimens in Mus. Acad. Nat. Sci., Bonap. col., presented by Dr. Wilson; one

specimen without name or locality.

TRITON MARMORATUS, JLatreille.

Char.—Body rough or warty, sometimes of a light green, or more or less deep with
marbled black spots, more or less confluent, or with spots of a brownish red upon a
ground of deeper brown; for the most part a yellow line, or band, or of a beautiful
carmine red, extending the whole length of the back from the nucha as far as the
middle portion of the tail; the under part of the body varies, sometimes it is black or
of 2 venous red, with white points, more or less sparse, and grouped together; some-
times it is very pale.’—Dum. et Bib.

Duméril and Bibron, who have especially observed this Triton, living and of dif
ferent ages, describe three varieties: 1. A line of a beautiful red, almost carmine,
extends all along the middle line of the back and tail, changing sometimes into orange
yellow ; throat and abdomen reddish venous brown, with small white points ; under
part of the tail of the same red color. 2. Brown above, with avery pale yellow dorsal
line; no spots upon the under part of the abdomen; under part of the tail red or
orange yellow. 3. One fourth the size of the first, perhaps the young; light grey
above, with a dorsal yellow line; rounded spots and black markings upon the sides;
sides of a uniform brown color; under part of the body reddish, without any spot,
or very distinct white spots. “ Most authors,” observe Duméril and Bibron, “regard
Triton marmoratus as a variety of Triton cristatus.”

Habitat Whole of France, especially the southern portion.

Remarks.—We have in the Bonaparte collection a single specimen marked Triton

360 HALLOWELL ON THE

marmoratus, which corresponds precisely with the figure of the same in the Fauna
Italica, of which it is, most probably, the original, which differs from the above des-
cription.: It is extremely rugose, of a uniform dark ash color; the markings upon
the sides very indistinct; an orange line under the tail; abdomen light orange, with
numerous irregularly shaped black spots of different sizes; more or less confluent.
It resembles very much some of the specimens of Triton cristatus, but there are no
round black spots upon the sides; and the dorsal line is absent. According to Kauf,
Triton marmoratus is found 6 inches in length, and exists also in the south of Spain.
According to A. Dugis, the tail is round in the winter, flattened at the nuptial
season. According to Duméril and Bibron, Triton nycthymerus is Triton carnifex,
the young of Triton marmoratus, but the specimen in the collection of the Academy,
marked Triton nycthymerus, is very different from carnifec and marmoratus. The
tongue is small and free behind, asin Pleurodeles. Triton nycthymerus is found in the
Tyrol and Picardy. Schlegel remarks that Zriton marmoratus is sometimes perfectly
smooth, without the slightest trace of tubercles. It is found, also, according to him
at Tunis.

Two fine specimens in Mus. Acad. N. S., presented by the Garden of Plants, corres-
ponding in every respect with the description of Duméril and Bibron.

TRITON PALMATUS.

Char.—“ Skin slightly granular, of a yellowish brown above, with two salient
dorsal lines, parallel to the salient line of the spine; the under part of the body of a
beautiful deep orange color, more yellow towards the sides; the posterior extremities
of the male, in the commencement of spring, of a darkish brown, with the five toes
almost entirely palmated; the females of a lighter color, with the tail almost round,
especially after having been a long time out of the water.’—Dum. et Bib.

Length 2 in. and 8 lines.

Habitat—F rance, England Germany. The most common Triton in the neighbor-
hood of Paris ; common also in the neighborhood of Montpelier.—Dugis.* T'wo speci-
mens presented by the Garden of Plants, 55 specimens in Mus. Acad. Nat. Sci.,

TRITON PUNCTATUS, Latreille.

Char.—“ Skin smooth, of an ash colored greenish brown, or yellowish above, with
black, rounded, distinct spots disposed very regularly and by lines; five black lines,
more or less distinct, uniting upon the anterior part of the head, of which one appears
to traverse the eye, advancing upon the sides of the neck ; the under part of the body

* Found throughout France. The female lays its eggs one by one, in the leaf of an aquatic plant, which it folds in
wo with its hind feet. In captivity and withont plants if Jets them roll freely into the water.—Dugis.

of a more or less deep yellow, and even orange, with large rounded black spots,
disposed in a somewhat regular manner, in two or three lines on each side.”—Dum.
et Bib.

Duméril & Bibron describe three varieties of the males and as many of the females
of this species: 1, with a very distinct crest, with the toes sometimes palmated or
semi-palmated, then becoming simple or not lobed; teniatus, Wolf, Gravenhorst,
Schneider ; punctatus, Latreille, Merrem ; palmipes, Daudin in Latreille. 2, crest scarcely
distinct, with the toes simple; punctatus, Daudin. 3, males in which the crest of the
back and tail are more apparent, as well as the membranes bordering the toes. Of
the females, the first variety are brown above, with two longitudinal lines of a deeper
color upon the back, and spotted with black beneath ; beneath small black spots in
the intervals between the large rounded spots, likewise upon the borders of the lower
jaw; tail yellow beneath. Length 2 inches 6 lines.

Habitat.—Very common in the neighborhood of Paris, and other parts of the north
of France; aquatic, oviparous.

62 specimens in Mus. Acad., Bonap. collection, presented by Dr. Wilson, labelled
Triton lobatus ; two or three of them labelled Nillson appear to be cristatus.

According to Dugis the exigwis is a young palmatus, and abdominalis, Latreille, the
young of the female of punctatus.

TRITON VITTATUS, Gray.

Sp. Char.—“ Body smooth, of a greyish white color, with large black points or.
spots arranged in longitudinal lines; a large yellow or reddish band, bordered with
black, above and below, extending upon the flanks, from the axillee and two-thirds
or more of the side of the tail; under part of the belly yellow or red, marked with
black points more or less abundant.’—D, & B. t.ix. p. 144.

Habitat.—France and England.

One specimen in Mus. Acad. Nat. Sci., presented by the Garden of Plants, another
larger, with the lateral stripe on both sides broad and well developed, by Dr. Bache,
forming part of the Green collection. Length of largest specimen 3 inches 10 lines ;
of tail 1 inch 9 lines.

Gen. Remarks.—According to Duméril and Bibron this is a doubtful species, being
intermediate in its characters between 7. alpestris and 7. punctatus. It is the Lisso-
triton palmipes of Bell, (British Reptiles,) the Molge and Ommatotriton vitiatus of
Gray.

TRITON PYRENazUS, Dum. & Bib.

Char.—Body warty or very rough, with salient points, brown upon the head and

sides, with a large yellow colored or safron dorsal ray, continued almost from the
92

362 HALLOWELL ON THE

nucha to the end of the tail, but denticulated irregularly with brown upon the edges,
and marked with isolated salient black points, few in number, upon the dorsal region.
The under part of the body, from between the angles of the jaw, the neck, the belly
and under part of tail, as well as the under part of the members, of a yellow or saffron
colored tint, with regularly defined margins.

Habitat.—Pyrenees.

TRITON SUBCRISTATUS, Schlegel,

Char.—Body warty, head large, flat and obtuse ; lateral tubercles at the commence-
ment of the neck; upper part of the body of a more or less deep brown, with a small
dorsal crest, as it were, effaced; under part of the body red, with irregular very deep
black spots ; the under part of the extremities of the same red color, with some small
spots or black points. (Gen. Cynops, T'schudi.)—D. & B.

Habitat. Japan.

Gen. Remarks—Dumeéril and Bibron say that Tschudi has separated this animal
from the Tiritons, giving it a name indicative of no character, supposing that the
tongue was adherent throughout, but in the account of this genus in the German of
Tschudi, the only mention I find made of the tongue is that it is “ sehr klein,” very
small. The generic characters are based upon the differences in the osteology of the
skull, which, he says, is quite different from that of Triton. Not having the specimens,
we cannot determine this point. Gray mentions the tongue as adherent, scarcely free
on the edges.—Cat. Br. Mus., p. 24.

Duméril and Bibron consider it as allied to Huproctus, Bonaparte and Gené. Du-
méril and Bibron, besides the above, describe five species from the Pyrenees, collected
by Bibron, viz. : rugosus, cinereus, repandus, punctulatus and Bibroni, which according
to A. Dugis and M. Gervais, as stated by them, are varieties of Huproctus ruscont.
For description of them, see their work, p. 150—154, t. ix.

DIEMYCTYLUS, Raf.

Char.—Tongue small, ovoid, adherent in front and superiorly, somewhat less at the
sides; no transverse palatine teeth ; two longitudinal series of palatine teeth in contact
in front, diverging posteriorly ; posterior nares quite large ; two longitudinal ridges
upon the cranium in contact in front, diverging posteriorly ; a bony bridge above the
orbit, as in Cynops and Huproctus ; spinous processes of vertebrae quadrangular, com-
pressed, laterally well developed; three foramina on the sides of the head, not com-
municating with the mouth; first and fifth toes rudimentary.

Gen. Remarks.—Diemyctylus, as observed by Prof. Baird, appears to be closely
related to Cynops, Tschudi, Molye pyrrohogastra, Boié. Isis, 1826, p. 215, Triton suberis-

CADUCIBRANCHIATE URODELE BATRACHIANS. 363

tatus, Dum. & Bib., vol ix. p. 140. In Cynops there are altogether 40 vertebrze and
16 dorsal,* the pelvis attached to the 15th and 16th. The ribs are larger and stouter
than in the European Salamanders ; the spinous processes very strong and broad,

arranged like a comb; vertebree of the tail much compressed, with strong processes
below. See Tschudi, Batrachier, p. 60.

DIEMYCTYLUS VIRIDESCENS, Raf.

Ohar.—Olive colored above, with ordinarily from three to eight small circular spots,
bordered with black, upon each side of the dorsal line; abdomen olive, dotted with
black ; tail more or less compressed, longer than head, neck and body; no parotids.
_ Length 3 inches 9 lines.

back a row of small, subrotund, crimson spots, bordered with black ; tail compressed,
of same length as body. Total length 2 inches 8 lines.

Syn. Salamadra symmetricus, Holbrook, North American Herpetology, vol. v.
p- 07, Pl. xvii.

Habitat.—Pennsyivania and Delaware.

Gen. Remarks.—This animal, as Dr. Holbrook remarks, appears to be distinct from
viridescens and Triton dorsalis, Holbrook, the latter living in the water, the other
being an inhabitant of the land.

Triton dorsalis,t (Notopthalmus miniatus, Raf.,) and Diemyctylus viridescens,
(2. symmetrica,) appear to be the same, the difference in their form and color
being attributable, in all probability, to differences of habitat and sexual pecu-
liarities. We have some specimens without any spots, others with only one, and
others with from three to eight on each side; the spots in all the specimens are small,
round, and bordered with a margin of black, and the body and abdomen more or less
minutely dotted with black. In some specimens, however, the upper surface is
orange, without spots. There may be described the following varieties—Ilst. Orange-
colored above, lighter upon the head, with three or four small, round spots, bordered
with black, on each side; underparts orange, sparsely dotted with black; a few black

* 14 according to Schlegel and 16 in Triton cristatus.

+ From the longitudinal stripe alone the middle line of the back.

dots upon the tail, (Zriton symmetricus, Holb.) It is to be observed, however, that
these spots are not always symmetrically disposed, but in the specimen before me,
the first on the right side is about two lines in advance of the same on the left, and
the number of spots is not always the same on each side; sometimes two spots on the
right side, four on the left, much smaller than the others and granulated.

2d. var. Same distinction of spots, skin almost smooth, abdomen more thickly dotted
with black; under parts orange, (millepunctatus, Storer, punctatissimus, Wood,) or
with a row of small circular spots, five in number, on each side, not very regularly
disposed ; probably an advanced age of No. 1.

4th. Tail more or less crested above and below; four or five or eight circular spots
bordered with black on each side, the two first on each side of the occiput, as in some
of the other varieties; body above and below very minutely dotted with black ; sides ©
of tail black spotted; spots large upon the root, nearly as large as those of Triton
eristatus. Inu some of them the circular spots are quite indistinct, or united to each
other forming longitudinal bands; in others there are no circular spots whatever, the
back being covered with brownish irregular lines; a longitudinal band of black run-
ning from the throat along the side of the head, neck and abdomen, and continued
along the tail; two black longitudinal lines on each side of the salient dorsal line,
and a longitudinal line on each side; the sides of the body, as well as the tail, are
spotted with black, the spots much larger upon the tail; under parts yellow, very
minutely punctated with black, (m¢llepunctatus, Storer.) We are informed by Prof.
Leidy, the vermillion colored specimens were found invariably upon land, and the
olive colored ones always in the water, or in marshy places, so that it would appear
that these, as stated by Prof. Holbrook, are really distinct species. It is to be regretted,
however, that we do not know more of the habits and mode of life of each.

We have received to-day, through Dr. Wilson, Prof. Leidy and Mr. Conrad, who
have been spending several weeks at Cresson, at the top of the Alleghanies, about
225 miles west of Philadelphia, at a height of 2300 feet, a considerable number of
specimens of .Diemyctylus miniatus, Raf., (iS. symmetrica, Holb.,) and Diemyctylus
viridescens, Raf., (Triton dorsalis, Holb.) The former present nothing remarkable,
and have been sufficiently well described. The latter present the following appear-
ances: These 13 specimens of Diemyctylus viridescens resemble each other very
closely. They are of an olive color above, deeper in some specimens than in others,
with a vertical yellow line extending from the occiput some distance upon the tail;
on each side is a row of vermillion spots bordered with black, varying in number, but
usually five or six on each side; sometimes.a few smaller ones may be observed
irregularly disposed. The yellow vertical line is often bordered with black, some-
times in the form of spots, at others assuming the form of a yellow band upon the

CADUCIBRANCHIATE URODELE BATRACHIANS. 365

single upper row on the right, and one below, very symmetrically disposed, in the small
specimens.

orbitar foramina are widely apart in Ceratophrys. The skull in Trigonephrys is
covered all over with well marked rugosities, the temporal fossee are much larger in
the latter; the skull itself is triangular in shape, depressed in front, hollowed between
the orbits, consisting of a solid bony case, with traces of sutures only in front of the
latter ; the orbitar foramina are subcircular in shape, measuring 42 lines transversely,
and are three lines apart; the occipital foramina are large and oval; upwards of
fifty recurved conical teeth may be counted in the upper jaw, the anterior much
the larger; the openings of the internal nares are oblong and quite large; two small
’ bunches of palatine teeth are situated at their inner extremities on a line with their
anterior margin; the nostrils are small, three lines apart, about four lines from the
anterior extremities of the cranium. ‘There are eight vertebra, exclusive of the
atlas and sacrum; the spinal processes of the first are much more developed than
those which follow; the transverse processes are seven in number, of these the

second and the third are the longest, the former measuring five lines in length; the

TRIGONOPHRYS RUGICEPS. 369

transverse processes of the sacral vertebree measure three lines in length and are
thicker at their external extremity ; the os coccygis is depressed, nine lines in length;
the iliac bones and those of the extremities present nothing remarkable; the sternum
does not differ materially from that of Ceratophrys. The difference in the structure
of the skeleton in this anima] and Rana pipiens, or common bull-frog, is very striking ;
indeed, it could hardly be greater in two genera belonging to the same family. The
orbitar foramina are more than double the size; the nasal openings very large; the
scapula remarkable for their great breadth, and the ribs are of nearly equal length.
Viscera.—The skin is very loosely attached to the thin and semi-transparent fascia
covering the muscles, its inner surface presenting numerous inosculating small vessels
distributed over its surface; immediately beneath this fascia two muscles shew them-
selves on each side, broad at their base and fanlike, the anterior inserted into the upper
surface of the humerus near its proximal extremity, the inferior into the symphisis pubis.
On cutting into the peritoneum ; the /iver consists of three lobes occupying the right and
a portion of the left side of ‘the abdominal cavity, the right lobe trefoil in shape, the
middle somewhat pyriform, and the left more or less quadrangular in shape, its anterior
margin presenting a waved outline; the gall bladder is quite distinct ; the heart lies
immediately above the liver, enclosed in its pericardium, and consists of a ventrical
and two auricles, the left comparatively empty, the right much distended with clots
of coagulated blood; the ventricle measures six lines in length by five in breadth ;
the esophagus communicates with the stomach by a large opening; the latter is a large
membranous sac, two inches five lines in length, by an inch and a half in breadth at
its greater extremity ; it occupies, when extended, nearly the whole of the left portion
of the abdominal cavity; on cutting into it, it was found to contain numerous Coleop-
tera, (Trox,) a portion of vegetable matter and the half digested skeleton of a hyla.
The intestine measures 14% inches (Fr.) in length from the pyloric orifice to the
commencement of the cloaca, the diameter of which, as usual, is larger than that of
the intestine, and measures in length about 53 inches. The ovaries are of a black
color, and contain a great many eggs of a yellow color, of the size of a pin’s head ;
the Jungs lie posterior to the other viscera, and, when somewhat distended, reach
nearly the whole length of the abdominal cavity ; the cells, as usual in the frogs, are
quite large, and divided by membranous septa ; the fatty bodies are much developed,
and present numerous subdivisions, thirteen on the right and seven on the left side ;
there is a very small triangular spleen ; the hidneys are one inch in length by three
in breadth. Ina specimen of Ceratophrys, about half the size of Vrigonophrys, the
liver presented three lobes deeply cleft, but the right lobe was destitute of the trefoil
arrangement of the former, the anterior margin being nearly straight, the lobe itself
triangular in shape; the specimen having been immersed in strong alcohol, the
4

370 HALLOWELL ON TRIGONOPHRYS RUGICEPS,

viscera are shrunken, but making allowance for this and its smaller size, the stomach
appears considerably less, being not more than an inch and a half in length, and the
intestine is much shorter, measuring but four inches three lines in length ; the fatty
bodies are much foliated, the kidneys measuring eight lines, the testes four in length.

Gen. Remarks.—The general shape of the head in this genus, resembles very much
that of Ceratophrys, along side of which it should be placed in anatural arrangement,
but it differs from Ceratophrys in the form of the eye-lids, which do not terminate
in the latter, and the form of the body has no resemblance to that of Trigonophrys.
The teeth also are different.

In Megalophrys, a genus inhabiting Java, and comprising but one species, (JZ. mon-
tana,) the first cuneiform bone presents no external prominence, which in Trigon-
ophrys is remarkably large. We, therefore, although not having in our collection
any of the allied genera, with the exception of Ceratophrys, venture to propose for this
singular and beautifully colored frog a new name. ‘The maxillary teeth form one of
its most striking characters, being larger than those of any species of frog with which
we are acquainted, those of the largest bull frog being considerably smaller, as well as
those of the large Surinam frogs in our collection. In Cystignathus ocellatus, however,
the vomerine teeth are much more developed.
