Not only are the young of this species very different in appearance from
the adult, but they are so variously striped and marked that a superficial ex-
amination might cause them to be considered the young of several distinct
species. The specimen described by Dana was not fully grown, and, like all
the immature specimens I have seen, had the teeth of the produced front
low and like lobes, with a short suture on the carapax between each lobe and
the next. In the adults, the teeth of the front are more separate and more
acute, and the central tooth more produced than the lateral ones; moreover,
the nine antero-lateral teeth are distinctly separated from each other, and the
body near the antero-lateral margins is thicker than in the young.

The prevailing color of the adult is red, becoming darker and more brown-
ish above, and orange or yellowish below. Among four young ones found
under stones at Monterey, two are chocolate, with a somewhat darker tint on
the elevated parts of the carapax; a third, bright yellow, with irregular
blotches of dark red; and the fourth, yellow, with narrow red stripes, giving
it a zebra-like appearance.

An examination of young and adult specimens only would lead to the be-
lief that they were distinct species, but a full series of specimens, of all sizes
and ages, reveals their specific identity.

This species is common in the bay of San Francisco, but I have never
found either it or its young beneath the stones on the beach, as is the case at
Monterey. In April of this year, half an hour’s search under the stones at
Preston’s Point, Tomales Bay, procured me twelve fine adult specimens, all
or most of them females. I did not observe any ova attached to them, and I

thought it singular that on a second visit paid to the spot in July, I could not
find a single female, though at low tide mark I secured an overgrown male
who had lost too many limbs to retreat with sufficient quickness.

This species appears to frequent deeper water than C. productus or C. magis-
ter, as, though occasionally taken on the lines of the anglers in San Fran-
cisco bay, I have never known of its occurrence on the beach between tides.
It is found on the ocean shore near Tomales, and occurs as far south as Mag-
dalena Bay, Lower California, where a fine specimen was obtained by Mr.
W. J. Fisher.

The sides of the chélipeds are beautifully marbled with dark spots upon a
lighter ground in adult recent specimens.

Sub-Family XANTHINE.

Until very lately not a single representative of this sub-family had been
found upon our western shores, probably because the the first collections
were made in the neighborhood of San Francisco.

7 The species named by Stimpson and Dana were collected at various locali-
ties from Monterey northward to Sitka, but the coast southward from the
former place to Cape St. Lucas, and the shores of the Gulf of California,
have been, and still are, comparatively unknown to carcinologists.

All the species of Xanthine described or mentioned in these notes have
been collected in the last mentioned localities by Mr. Hy. Hemphill and Mr.
Wi oe Hisher.

Those species which I have previously described from single specimens
furnished to the Academy by the former collector are most of them more
fully known to me by numerous specimens obtained by the latter during five
months spent in dredging and collecting along the uninviting shores of Lower
California, while those which are new are in every case the results of the same
indefatigable collector’s labors.

It is somev hat singular that, so far as I am aware, nota single species of
this sub-family has yet been found along the shores of Northern California,
Oregon, or Washington Territory, and I cannot avoid thinking that further
search may disclose some.

The genus Punopeus is represented on the shores of Central America by
two or three forms which have not hitherto been found so far north as Lower
California.

I own myself unable to perceive any sufficient reason for the separation of
Xantho from Xanthodes, but I have relegated two of the narrowest forms to

the latter group.

_Entire upper surface of the carapax covered with involved ruge; those of
each areolet distinct; areolets separated by sulci.

Chelipeds equal, their upper outer surface rugose like the carapax, the
rug giving way to rows of tubercles on the underside of the manus.

Upper edge of the manus and carpus an acute angle; inner surface of both
perfectly smooth; meros smooth on both sides, compressed.

Hinder limbs with compressed joints; the meros smooth on both sides, ex-
cept in the fifth pair; the remaining joints rugose on their upper and posterior
aspects. Meros of fifth pair rugose above. Fingers of chelipeds sulcate,
short. Sternum cavernous; abdomen with transverse rug. Color, in spirits,
dull red.

Locality, Mulege Bay, Gulf of California.

Two specimens, a male and female, are all I have seen of this well marked

species.

This little crab has a peculiarly compact appearance. The rugosities of its
limbs are so arranged that when they are folded up close to the carapax not a
portion of smooth surface can be seen either above or below, the only smooth
portions being lateral and hidden.

Form of carapax as in Actwa, but with an external hiatus to the orbit, and

Tam loth to form a new genus for a species which resembles an Acta so
closely in its general aspect and form, which, in my belief, afford far better
evidence of the real affinities of any animal than are afforded by variations iu
the form of the orbit or the length of the basal joint of an antenna; but I
have no choice in the matter, as the genus Acta is defined as ‘‘ without an
external hiatus to the orbit,’’ while the genera with the lower margin of the
orbit divided into teeth have a seven-jointed abdomen in the male.

All but one of the specimens from Lower California are smaller than the

tionally narrower, yet I believe them to be younger individuals of the same
species, founding my belief on the prominent, narrow, entire part, curved
outline of the autero-lateral margin, without perceptible angle at its junction
with the postero-lateral; and on the character of the left cheliped. the fingers
of which are sulcate, and devoid of prominent tubercles on their palmar

surface.

Xantho Hemphilliana. Lockington, Proc. Cal. Acad. Scei., Feb. 7th, 1876.

The only specimen I have seen of this species is the one in the possession
of the Academy of Sciences, San Francisco. Some small crabs from the
Gulf of California, which I at first believed to be young specimens of this
form, differ in their less transverse form and more perfect areolation, and I
now think them distinct, yet this can only be proved by the examination of
a complete series of the Monterey form.

and directed laterally, the space usually occupied by the first two antero-lat-
eral teeth forming an almost straight line. Basal joint of onter antennse

sinuate, a process meeting the basal joint of the external antennz. Internal

Numerous specitoens of this species were brought from La Paz, Port Es-
condido and Malege Bay, Gulf of California, by W. J. Fisher. They show
great variation in color, areolation, and other characters. In some the poste-
rior portion of the carapax is much less distinctly areolated than in others;
many individuals have the upper surface of the carpus, and even that of the
manus, more or less rugose; some have black fingers with white tips, others
have colored fingers, and the general tint of the carapax varies considerably.
The original specimens from which my previous short description of this spe-
cies was written, were lost in removing our collection, and I cannot, there-
fore, feel certain of the identity of the Gulf form with the one first described.

Xanthodes? angustus. voy. sp.

Carapax narrow, front wide, slightly sinuate; antero-lateral margin shorter

~~ than postero-lateral, three-toothed; teeth pointed forwards; the posterior

margin of the hindermost teeth in a line with the postero-lateral margin.
Upper margin of the orbit two-lobed, excluding the post-orbital, which is lower
than the two succeeding antero-lateral teeth. Upper surface of the carapax
smooth, shining, without areolation, except in the frontal region, and near the
antero-lateral teeth. Chelipeds smooth, shining, without areolation, hairs or
tubercles, hands rather broad, equal in size, fingers of right hand tuberculate

These dimensions are from one of the largest specimens.

The extreme narrowness of the carayax and shortness of the antero-lateral
margin make me doubtful of the propriety of placing this species in the sub-
genus Xanthodes. Its aspect is much that of a Pilodius, but the fingers are not
spoon-shaped. There are a few scattered sete on the two last joints of the
ambulatory feet. There is considerable resemblance between this species and
X. latimanus from San Diego, but the hands of the former are wider and the
antero-lateral teeth more robust. The difference in size between the present
form and the single male of X. latimanus in the Mus. Cal. Acad. Sci. is great,
but it is not unlikely that it is either the young or a small variety of that spe-
cies, but as the gulf species are in most cases distinct from those of the west
coast of Lower California, I do not venture to unite them.

granulated, the granulations with a tendency to form beaded ridges. Intra-
medial and extra-medial regions distinct from each other and from the antero-
lateral. First two teeth of antero-lateral margin coalesced, forming a promi-
nent bi-lobed tooth; third and fourth teeth curved forwards, the fourth short-
est; fifth thick and rounded, directed forwards. Sub-hepatic spine promi-
nent. Inferior margin of orbit three-lobed; interior lobe inconspicuous; mid-
dle lobe narrow, thick, projecting; outer lobe long, low, thin, highest on its
outer angle. Outer hiatus of orbit deep and narrow. Superior margin of
orbit with slight indications of a division into three lobes. Chelipeds smooth,
unarmed, the right the larger; propodi and dactyli of hinder limbs beset with
short bristly hairs. Color of carapax and upper surface of chelipeds bluish
purple, becoming darker in the older specimens. Irregular spots and blotches
of a dark brownish purple are conspicuous in the younger specimens, but be-
come indistinct in the older, except upon the chelipeds. Fingers brown, with

Numerous specimens of a small species of Panopeus from Lower California
do not agree at all with any of the species described by 8. I. Smith, in the
Proc. Boston Soc. Nat. Hist., vol. XII, Feb. 3, 1869, and from their transverse
shape and the small size of the sub-hepatic spine, may probably be the P.
transversus of Stimpson. As, however, I have no access to Stimpson’s de-
scription, I think it well to subjoin a short description, as it may possibly
prove to be a distinct species. Front slightly sinuate, antero-lateral teeth
four, the two first long and low, the last two more pointed, with the points
turned forwards. Right cheliped slightly the larger, both chelipeds smooth,
shining, whitish, except on the upper surface, where the tint deepens to a
reddish brown, which is the general color of the carapax. Hinder pairs of
legs tomentose. Two of the largest specimens measured as follows:

No species of this group is mentioned by Stimpson, either in Crust. and

have here described three species, all of which were brought from Lower Cal-
ifornia by Mr. W. J. Fisher. Although distinguished as a sub-family on ac-
count of the more or less perfect spoon-shaped tips of the dactylus and pollex
of the chelipeds, the Chlorodine are so closely related to the Nunthine that
it would be more natural to intercalate their genera among those of that sub-
family; for instance, Chlorodius next to Xantho, and Actewodes next to Acta.

A single specimen, female, from San José Island, Amortiguado Bay, Gulf
of California. In spirits, the areolets are of a bright yellow color. There are
five tubercles on the carpus, and as many on the hand. The genera Acteu
and Acteodes are usually placed in separate sub-families, but the artificiality

of this separation is evident to any one who compares the species belonging _

to the two genera. In this species, as in A. speciosa and A. cavipes, Dana,
and A. mevicanus (miht), the tips of the fingers are but imperfectly excavate,
and the forms belong as truly to Actea as to Acteodes. The two genera form,
in fact, a continuous series of closely allied species.

Chlorodius Fishert. nov. sp.

Similar in proportions to C. sanguineus, Edwds, but the carapax is widest
between the posterior teeth of the antero-lateral maigin. Front 4-lobed; a
deep emargination between the long central lobes. Teeth of antero-lateral
margin five in number, acute, sub-equal, and directed forwards Areolation
less distinct than in C. sanguineus; areolets well-defined anteriorly, but.not
posteriorly. Pre-medial areolets joined to the extra-medial; intra-medial sep-
arated from the posterior or cardiac by a distinct sulcus; areolets of antero-late-
ral region six in number; postero-lateral and posterior regions without distinct
areolation. Chelipeds equal, smooth, except a tooth on inner angle of car-
pus; all the fingers spoon-shaped, but the cavity not circumscribed within.
The fingers are sulcated. Posterior legs slightly setose, claws sharp.

Color. Carapax, greenish red; chelipeds, marbled with purplish red, white
beneath; fingers, black. Length of carapax of largest specimen (male), 0.78
in.; greatest width, 1.06 in.

Numerous specimens trom the West coast of Lower California, collected by
W. J. Fisher, also from La Paz, San José Island, Mulege Bay and Port Es-
condido, all in the gulf of California. It is found on the flats at low tide.

When Stimpson, in 1857, published his ‘* Crustacea and Echinodermata of
the Pacific Shores of North America,’’ not a single species of the large fam-
ily Portunide had been discovered. ‘The same naturalist in his ‘“ Notes on
North American Crustacea,’’ published in 1859, mentions one species, Lupa
bellicosa, Sloat, MS., but gives no description, remarking that it ‘‘ agrees with
L. hastata in almost every character, except that the last two joints of the ab-
domen in the male are broader and more flattened.”

Tn February of this year I described a second species, a specimen of which
had been procured the preceding year at Mazatlan by Mr. Henry Edwards;
and I shall in this paper describe a third, of which many individuals have
been collected by Mr. W. J. Fisher at various points on the Western and
Eastern shores of Lower California. At Magdalena Bay Mr. Fisher procured
several very specimens of a Zupu, which I take to be the ZF. bellicosa of Sloat
and Stimpson, but as Sloat’s MS. is not on hand, and Stimpson gives no
figure, my sole reason for this belief is that the other two known species from
Lower California, belong to the genus Amphitrite, as detined by Dana.

That there may be no confusion I append a description of this Lupa.

Lupa bellicosa? Sloat, MS. Stimpson. Notes on N. Amer. Crust., p. 11. -

Carapax regularly arched in its longitudinal and transverse directions; ex-
ceedingly wide, the post and antero-lateral outlines forming a long ellipse;
no areolation except a sulcus between the median and posterior regions.
Central tooth of front placed low down, between the internal antenne, and
separated by a short, somewhat pilose, space from the front proper, which
has two lateral spines separated by a sinuous central portion. Upper margin
of the orbit consisting of two long teeth, an ante and post-orbital; the former
highest above the outer antennie, and separated by a deep notch from the
latter, which is two-lobed, the anterior lobe low, and the posterior long and
pointed. Antero-lateral teeth nine, including the posterior lobe of the post-
orbital, which exceeds in height any of the others except the ninth. 2d, 3d,

Ninth tooth much the largest, its upper ridged edge continuing across the
carapax for some distance. Lower margin of the orbit pilose, rising into a
conspicuous tooth immediately below the outer antenne. Underside of eara-
pax and sternum without hairs, except below the hinder part of the antero-
lateral regions. Meros of first pair trigonal, with four sharp spines on its
upper anterior edge and two blunt teeth at the distal extremity of its poste-
rior edge. Carpus with two or three ridges exteriorly, and some sbort, blunt
spines anteriorly. Manus with a triangular tooth next the carpus on its
upper anterior edge, and also a blunt tooth at the distal extremity of its upper
posterior margin. Dactyli only slightly suleate; the teeth of the inner mar-
gins in groups of three; the central one largest. Second, third, and fourth
pairs of limbs stout; the two last joints compressed and sulcate, pilose pos-
teriorly. Fifth pair stout, without suleations on the last two compressed

On looking over a number of Amphitrites from Lower California, I found
one only, a large female, that can be referred to this species.

It presents all the characters of the type in the Academy’s museum, but in
a more marked degree from its larger size. The nine spines of the antero-
lateral margin are alternately large and small, the ninth no larger than the
first, third, fifth, and seventh; and the points of all are black. The meros
of the first pair of legs has five black-tipped spines, that nearest the carpus
smaller than the central three and equal to the proximal one. The inter-
orbital teeth are eight in number, and the ridges across the carapax well de-
fined. The spines of carpus and manus agree exactly with those of the
smaller specimen, previously described, and all are tipped with black.

The general color of the carapax and limbs, in spirits, is red, with lighter
marblings. The tips of the fingers are black.

Inter-antennal front four-lobed; pre-orbital spines slightly two-lobed.
Antero-lateral spines were nearly equal in size, except the ninth, which is
twice the length of the others. The outline of front portion of carapax be-
tween the last antero-lateral spines, on each side, is a regular ellipse. Pos-
terior to the last antero-lateral spine the carapax contracts suddenly in width,
so that the postero-lateral margins are L-shaped. Meros of first pair with
four spines on its apterior margin, the proximal smallest. Carpus with one
spine on the interior upper margin, and two on the exterior. Manus with
one spine only, on its upper margin, forming the extremity of a carina. Four
slightly beaded ridges on the outer side of the manus. Fingers sulcate,

Mithraculus coronatus (Stimpson). Mr. Streets does not state on which side
of the Isthmus the various species enumerated in his catalogue were col-

occurs on both sides, I shall not in future include in this catalogue any but
undoubtedly Pacific species.

W. N. Lockington read the following:
Notes on Californian Fishes.
BY W. N. LOCKINGTON.

Raia batis. Linn.

Uraptera binoculata, Girard.

Dr. A. Gunther, in the Cat. Fishes Brit. Mus., Vol. VIII, p. 465, states his
belief that the latter of these fishes may be regarded as a climatic variety of
R. batis. He goes on to say that ‘‘ young examples have a round obscure spot
on each pectoral fin.”’

Had Dr. Gunther seen the fish alive, or in a fresh condition, I think that
his opinion would have been different, but, as the Catalogue shows. his only
specimens were young, one from San Francisco, presented by Dr..W. O.
Ayres, the other a skin only, presented by J. Keast Lord, from Vancouver
Island.

ACADEMY OF SCIENCES. 15

I have myself seen specimens of large size in which the spot is as distinct
as in the young, and though I cannot say I have measured them, I feel
assured that one I saw in the aquarium at Woodward’s Gardens about a
year ago was two feet across the fins; and that the one now there is about
eighteen inches.

Moreover, the eye-like spot in the centre of the pectoral is anything but
obscure in the recent fish, it is most conspicuous.

But this is not all. We have in our possession a fish (caught in San Fran-
cisco Bay,) which agrees in every respect with the description of R. batis in
the Brit. Mus. Cat.

I subjoin the dimensions—

Body and fins of a uniform slaty brown color. The difference in aspect
between this fish and the Uraptera or Raia binoculata is very great.

Body oblong, compressed; head contained four and a half times in the total
length; outline of top of head nearly straight, slightly concave, ridges of up-
per surface prominent; depth increasing to origin of first dorsal, thence nearly
equal to root of second dorsal, thence decreasing gently to peduncle of tail.
First dorsal with eight spines—the first minute; the second about one-sixth
the length of the third; third, longest, very stout; fourth, fifth, sixth and sevy-
enth rapidly decreasing; eighth, prostrate. Pectorals small, extending to
little more than the half length of the ventrals, which exceed them in size.
First spine of anal very small; second, long and stout; third, slender, but
slightly the longest. The orbit is slightly elliptical. Lower jaw protruding
beyond the upper; maxillary, when the mouth is closed, extending to a per-
pendicular from the centre of the pupil. Teeth nominal. Pre-operculum
strongly serrated. Color, when fresh, back to lateral line dark green, be-
coming lighter below, and whitish on the belly. Snout, green, yellow on the

The single specimen was taken by Mr. W. J. Fisher, off Asuncion Island,

The proportions and coloration of this fish agree very nearly with those of
Centropomus undecimalis, Cuv. and Val.; and I strongly suspect its identity
with that species, which is, however, not known to me from specimens or
figures.

(. undecimalis is a native of the Atlantic shores of tropical America; but Dr.
Gunther queries its occurrence at-Lima. If it should prove, on further ac-
quaintance, to be a distinct species, I propose to name it Centropomus viridis.

As I have not seen Edwards’ description of this species, I subjoin a short
description:

Carapax slightly wider across the centre than in front. Lateral angles
of anterior margin very prominent, upper orbital border sinuate; front
narrow, eyes large. Right cheliped much larger than the left in both
sexes; arm trigonal, with its inferior surface somewhat concave, in conse-
quence of both its margins being slightly raised and beset with spinous
tubercles: the upper margin rounded, rugose with rows of small tubercles.
Carpus short and stout, with a sharp spine on its anterior border at distal
end, and rows of small tubercles above, becoming more prominent and some-
what spinose distally. Manus broad aud thin, covered with tubercles ex-
teriorly; a row of saw-like spines along the lower margin continued along
the propodal finger, which is cristate, hooked at end, and with several teeth
internally. Movable finger similar to fixed, spinose along its upper margin.

Ambulatory limbs flattened; merus with a sort of roll on its upper margin,
crossed by tubercular ruge. Carpi of second, third and fourth pairs setose
at distal lower extremity; propodi of the same three pairs setose below;
carpus and propodus of fifth pair without hairs; all the dactyli fringed in
front with sete. Third joint of outer maxillipeds narrower, and about
half the length of the second joint.

First two segments of male abdomen very short; third and fourth longen,
fifth still longer, sixth longest. Fifth segment narrowest; sixth convex on
both sides; seventh a small truncate triangle. Fourth and fifth segments of

female abdomen widest; sixth a semi-ellipse, with the small seventh segment
inserted in a coneavity of the anterior margin.

Gentis Gelasimus.

Six species of this genus are included in the collection of Mr W. J.
Fisher. One only of these belongs to the section having a narrow front, with
the bases of the ocular peduncles close together. This is the (. princeps of
S. T. Smith.

Another species, having the fourth, fifth and sixth abdominal segments
united, is certainly the (. gibbosus of the same author. Another I believe to
be the G. brevifrons of Stimpson.

None of the remaining kinds answer to Stimpson’s and Smith’s description
of 4. panamensis, so that unless two of them are referable to the Chilian
species, (. macrodactylus and G. stenodactylus, it is fair to suppose they are
new species. I have described two of them as new, and the remaining one,
with some misgiving, I provisionally refer to 4. stenodactylus.

Thave not seen Stimpson’s description of this species, but from Smith’s
comparison of its carapax with that of G. minaz, I conclude that several
specimens collected by Mr. Fisher on the West Coast of Lower California,
belong to this species. The meros of the larger cheliped is stout, triquetral,
and marked on its exterior surface with transverse setose strie; the carpus
has a rounded tooth at its inferior distal end, and the manus is large and
heavy, twice as large as the width of the carapax, the palmar portion rounded
and smooth, but minutely granular on the outside, and on the inside beset
with small tubercles on its more elevated portions. The depression for the
carpus is short but very deep, the thin upper edge of manus curving inwards
over it. The propodal finger is slightly deflected downwards, and the dac-
tylus curved from the base, the curve increasing towards the tip. The
tubercles of the inner edges of the fingers are very indistinct, except one
near the centre of the propodal finger, and another close to the tip, which
thus appears bifid.

In the smaller cheliped the tips of the fingers are obtuse and rounded, and
the outer edges raised, so that they are imperfectly spoon-shaped. The dac-
tylus and propodal finger are almost parallel and near each other, but touch
only at the tip, where they have a few sete.

The meral segments of the ambulatory legs are plicate, like those of the
chelipeds.

Following are the dimensions of two large specimens:

pl. 11, f.2. M. Edwds. Ann. des Sci. Nat., 3d serie. Zoél., tome
xviii., p. 149. §. T. Smith, loc. cit., 139.

I have not seen the description of this species by Edwds. and Lucas, and
therefore question its identity with a single male specimen of a (re/asimus
with very short fingers that was brought from the West Coast of Lower Cali-
fornia by My. Fisher.

The fingers of the larger cheliped are very short, the dactylus does not
attain the length of the inferior margin of the palm, and the propodal finger
is much shorter.

The manus of the smaller cheliped resembles that of (. gibbosus. The
carapax is highly convex, the anterior lateral angles almost in a line with the
front, so that the orbital border is but slightly sinuous; the inferior orbital
border dentate, and the lateral margins converging.

Gelasimus vectilatus, nov. sp. 2

Among the (relasimi collected by Mr. Fisher on the West Coast of Lower
California are two specimens which I cannot refer to either of the broad-
fronted species from this coast, described by 8. I. Smith and Stimpson, viz:
G, gibbosus, G. panamensis and (, brevifrons. As I have not seen the descrip-
tions of G. macrodactylus and G, stenodactylus, it may possibly be one of these,
though neither name seems applicable.

I append a short description:

Front narrower than usual in the broad-fronted section of this genus, not
much more than half the width of the bueeal frame; carapax tapering pos-
teriorly, the sides forming an almost straight line from the antero-lateral
angles to the straight posterior margin; antero-lateral angles much posterior
to the line of the front, acute and with considerable lateral projection. Up-
per orbital border highly sinuous entire, lower orbital border toothed at its
outer angle. Outer maxillipeds greatly gibbous, the buecal area separated
from the jugal by a distinct depression. Larger cheliped smooth (micro-
scopically granulated), except on inner surface of manus, where there
is a line of small tubercles on the inner edge of the propodal finger, and a
second on the ridge proceeding upwards from the lower edge of that finger.
Fingers tubercular on their inner edges, the largest tubercles that in the
centre of the length of each, and that near the tip of propodal finger.
Fingers of smaller cheliped parallel, equal, imperfectly spoon-shaped.

Hands of female similar to the smaller cheliped of male. Ambulatory feet

entirely smooth, with a few hairs. Abdomen of male with all the joints dis-
tinct, gradually narrowing from the base.

The larger hand greatly resembles that of the species I have referred to
G. brevifrons, but the fingers are proportionally shorter, a character which
may, however, be due to immaturity. The great differences between this
form and G. brevifrons are the entire want of the meral plications, and the
form of the lateral margins of the cavapax, which in the latter continue
nearly perpendicular to the front for some distance before they commence to
converge.

A single pair is all I have seen of this form. The great convexity of the
carapax, and the absence of any coarse granules on the front and anterior
part of the branchial regions, distinguish it from G. pusamensis.

Gelasimus crenuldtus. Nov. sp.

Carapax highly convex, transverse, antero-lateral angles acute aud promi-
nent, slightly posterior to the front; superior orbital margin sinuous, inferior
crenulated, the teeth equal in size and with a straight upper edge.

Dorsal surface smooth and shining; median and lateral gastric regions
clearly marked off; cardiac distinct; branchial regions prominent, tumid,
each divided in two by an indistinct sulcus, parallel with the literal margins
of the carapax.

A broad ridge on the inner edge of the fourth joint of outer maxillipeds,
continued downwards along the greater portion of the inner edge of the third
joint. Merus of greater cheliped stout, triquetral, marked with numerous
short, transverse, not prominent rug, Carpus and manus smooth and un-
armed, except a few small tubercles on the raised line anterior to the de_
pression for the carpus on the inside of the manus. Propodal finger long
and slender, pointed at tip, and with a tubercle in the centre of its length.
Dactylus longer than propodal finger, curved, the tip of the curve consider-
ably overpassing that of the latter. Merus of smaller hand slender, tri-
quetral, smooth, carpus smooth, about equal in length to the palm of the
manus; fingers equal, parallel, near together, touching at tips, which are
pointed.

Hands of female like those of smaller male cheliped. Ambulatory feet
smooth and shining, with a few long sete on the propodi, and more numer-
ous and shorter setze on the dactyli.

The hand of this species is similar to that of G. brevifrons: the gibbous.
carapax, with its areolations, resembles closely G. gibbosus, but the third,
fourth and fifth segments of the abdomen are free, instead of anchylosed, as
in that species; and the margins of the carapax again resemble those of the
species I have referred to @. brevifrons, but the convexity of the surface, with
the tumid branchial regions, give it a very different appearance.

Unless this is the G. macrodactylus of M. Edwards, found on the coast of
Chili, it is certainly a new species.

Numerous specimens from the West Coast of Lower California, principally
from San Bartolomé Bay, agree with Smith’s description and figure of this
species in every particular, except in having the front more suddenly curved
forwards. The sub-hepatic regions are thickly setose.

The fingers of the smaller cheliped are equal in leneth, and twice as long
as the broad, stout, and short palmar portion of the manus: they are widely
separated at their base, gape throughout their length, and are curved to meet
each other at their extremities, which are of a yellowish brown tint. There
are a few scattered hairs on the fingers. In the female both chelipeds are
exactly like the smaller cheliped of the male.

The depression between the buccal and sub-hepatic (jugal) areas is very
distinct; the teeth of the inferior margin of the orbit increase in size and
slenderness on the outer portion; and the fourth, fifth and sixth abdominal
segments are anchylosed. The prevailing tint of the carapax and limbs (in
spirits) is blue, of varying intensity, shading in parts into greenish and into
white on the fingers of the chelipeds. Many very small specimens have the
fingers of the larger cheliped but little developed, not exceeding the palm in
length, and closely approximated to each other.

At first I thought these to be a distinct variety, but now believe them to be
the young of the same species, as they agree in every other particular, aud
some show evidences of a change in the relative proportions of the palm and
dactyli as growth progresses.

Caurdiosoma crassum.? $. I. Smith, loc. cit., 144; pl. v., f. 5. Gulf of Fon-

A single fine male specimen from the latter locality agrees in most par-
ticulars with the figure and description referred to, but the carina of the
lateral margin is much less distinct and high; and the larger hand differs in
form.

As the specimen exceeds in size any of those measured by Mr. Smith, I
think it possible that the differences referred to may be owing to the greater
age of the individual; but as it may possibly prove to be a different species,
T append a description of the chelipeds.

exceeding the length of the superior margin. Propodal finger slender and
straight, slightly spoon-shaped at extremity, with a large tooth near the

centre of its length, and several smaller teeth. Distal end of manus forming
an angle of about 80° with the superior margin, and of about 60° with the
propodal finger, which does not increase greatly in width towards its base.
Dactylus slender with a large tooth nearer the base than the tip, which is in-
flated and spoon-shaped. Inner surface of the hand, towards the margins,
armed with scattered tubercles of small size. Upper portion of manus curv-
ing inwards posteriorly, the carpus fitting, when the hand is bent, into the
hollow between the upper incurved carina and lower thick portion of the
manus. The smaller hand is similar to the larger. The stoutness of body of
this crustacean is such that the sides of the branchial and hepatic regions are
visible from above, and protrude laterally beyond the antero-lateral carina.
The male appendages agree with those of C. crasswm.

tendency to split up into tubercles. Tubercles of manus arranged in longitu-
dinal rows along its upper margin. Ambulatory legs, with the distal end of
merus three-toothed, the upper tooth sharp, the two others long and rounded
lobes; terminal joints with scattered hairs; dactyli spinose. Abdomen of
the male with the two first joints very short, the third joint widest, and with
strongly convex sides; remaining joints regularly diminishing in width, with
a slight convexity. Color citrine, with a variable reticulation of dark brown,

The branchial regions are much elevated in old specimens.

I have preferred to employ Dana’s name of Goniograpsus in preference to
Randall’s Pachygrapsus, as the generic characters given by the former author
are the more precise and definite.

This species appears to be very near to the Goniopsis eruentutus of De
Haan, but that species has the hand, carpus, and dactylus small spinulous

Two females from the latter locality have the peculiar bifurcate dactyli,
from which Mr. 8. [. Smith has named the genus Dissodactylus, and prob-
ably belong to D. nitidus, of which that author describes the male. The car-
apax is firm, somewhat wider at the lateral angles than posteriorly; convex in
front and at the margins, without any upturned border along the antero-lat-
eral margin, but with a short fissure extending obliquely inwards immediately
anterior to the lateral angle. The posterior margin has an upturned border,
There is no pubescent tuft on the inferior edge of the propodal finger. The
ambulatory legs are as in the male. The abdomen resembles that of Pinno-
theres, the terminal article reaching and partly covering the buccalframe. The
prevailing color is dark purplish brown, with spots of white upon the carapax,
and a ring of white at each joint of the limbs. The dactyli are white.

37. Pinnixa ? nitida. nov. sp.

Male. Carapax exceedingly transverse, smooth, shining, color in spirits,
bright orange; all the limbs smooth and shining, without pubescence, of a
straw yellow color. Maxillipeds very small and triangular, closely fitted to
the buceal area, smooth and shining, as is also the sternum. Abdomen nar-
now at base, second segment rapidly widening, third widest, fourth, fifth and
sixth tapering rapidly, seventh almost as long as wide, triangular, with the
apex rounded. The abdomen does not cover more than one-half the sternal
area. Chelipeds shorter than either second or third pair, the manus broad,
with two setose ridges on its anterior surface, fingers short, hooked, toothless,
movable finger oblique. Three last joints of ambulatory limbs flattened, car-
pus broad at distal extremity, scarcely longer than wide; propodus nearly twice
as long as wide; dactylus slender, cylindrical, white, ending in a sharp yellow
claw. Margins of last three joints setose, second pair (first ambulatory pair)

A single specimen of each the two crustaceans just described was collected
on the same day at the same locality, namely, Angeles Bay, Gulf of Califor-
nia, and the two were placed by the collector (Mr. W. J. Fisher) in the same
phial. Had it not been for this, I should certainly have never linked
together two specimens so distinct in the relative proportions of the limbs
themselves, as well as of the joints of those limbs; one covered in many
places with an abundant pubescence, the other smooth and shining above
and below. The proportions of the ambulatory limbs in the female agree
with the genus Pinnixa, but in the male the increase of size is transferred to
the second pair. Should these crustacea prove to be distinct the female
should be Pinnixu tomentosa, while the male must be placed in some other
genus.

I have no means of ascertaining upon what species of invertebrate animal
these crustacea resided as commensais.

38. Pinnixa longipes. (Tubicola longipes. Lockington, Proc. Cal. Acad.
Sci., April 17, 1876.)

his species should properly be placed in the genus Pinnixa. It possesses
the characters of transverse carapax, and elongated fourth pair, in an extra-
ordinary degree.

No. 60. Tomales Bay. (Lockington.) in spirits.

When I wrote the description of this species, I was not aware that any
species of Pinnothere had previously been found quartered upon a worm, but
I have since found that Stimpson (Notes on N. Amer. Crust., 21, 23) men-
tions two species, both belonging to this genus, that live in similar localities.

These species are, P. cylindrica, which inhabits the tube of the Chertopterus,
of South Carolina, and P. l@vigata, which lives with the lobworm, Arenicula
eristala, in its hole, not lined by any tube, in the sand. \
