ANOMURAN COLLECTIONS MADE IN PORTO RICO. 
145 
tip — margins of apex entire. Antennae short; terminal joint of peduncle and flagellum very slender, 
almost naked; acicle slender, spinous, and hairy. Chelipeds equal, broad and depressed, almost 
naked; merus scabrous above; carpus minutely spinulose and armed with four spines on the inner 
edge; hand uniformly minutely granulated with five tubercles on the inner edge of the palm; fingers 
with sharji cutting inner edges; tips not spiniform; immovable finger concave below; dactyls nearly 
three times as long as the inner edge of the palm. Ambulatory feet above scabrous, spinulose, and 
setose; clactyli, with a dense series of longer setai along the superior and inferior edges. The inner 
side of the penult and terminal joints in the left second foot is concave. 
The following are the measurements of a female specimen: total length, 3 inches; length of 
carapace, 0.77; breadth of front, 0.40; length of eye, 0.41; length of chelipeds, 1.05 inches.” 
A male and a female of this species were taken by the Fish Hawk at Mayaguez, Porto Rico. The 
eye-stalks and chelipeds are a rich orange red. The species is readily distinguished from all others of 
the genus yet found in the West Indian region by the broad, spineless, evenly granulated hands; its 
nearest relative is the Paguristes digueti, of Bouvier, found on the west coast of Mexico.

The rostrum is broad at the base, the sides are straight, meeting at the sharp apex; from the 
lateral projections the front retreats rapidly and rounds into the sides without forming an appreciable 
angle, as in P. lymani and P. sayi. The eye-stalks are very much longer than the greatest width of 
carapace. The carapace is more convex than in any other species of the depresms section of the genus. 
The peduncles of the antennula reach the cornea; those of the antenna are about half the length of 
the eyes, the terminal segments are unarmed, acicles elongated, slender, with tips 2 or 3 spined. 
Taken by the Albatross, at station 2354, in 130 fathoms, one female. 
Paguristes rectifrons, new species. Plate 4, fig. 7. 
The rostrum is triangular and is inserted posterior to the general line of the front. The front is 
remarkable for its linear appearance from angle to angle; the projections between the eyes and antenna 
are low; between the bases of these projections and the antero-lateral angles the margin is straight. 
The eye-stalks are but little shorter than the width of the front. The peduncles of the antennula 
reach the cornea, those of the antenna but little more than one-half of the eye-stalk; the terminal 
segments of the antenna are armed with two spines; the acicle is forked and has a prominent spine on 
the side. The carapace is flattened and has several spines on the side. The chelipeds are short and 
rather stout, the carpus is broad, with two large spines on the inner margin and several smaller ones 
on the surface near by ; the hand is broad and is shaped very much as the hand of P. sericeus, as shown 
in fig. 17, pi. hi, Blake Paguridse, Edwards & Bouvier. The crest is armed with five spines; spines of 
smaller size fringe the lower margin and the margin of the dactyl. 
Paguristes rectifrons is separated from P. sericeus by the much shorter eye-stalks, by the front, which 
in sericeus is not so straight, and by the different armature of the hand and carpus. 
Dredged by the Fish Hawk, at station 6085, in 14 fathoms, one male in the shell of Strornbus 
pugilis.

Paguristes lymani A. Milne-Edwards & Bouvier, Mem. Mus. Comp. Zool., xiv, No. 3, p. 49, pi. iv, figs. 13-22, 1893. 
The rostrum is a rounded lobe in the sinus behind the eyes; from the projections which limit 
this sinus the front rounds gradually into the lateral margin. The eye-stalks are short; when laid off 
on the front they reach from the middle of the insertion of one antenna to the middle of the other. 
The peduncles of the antenna reach the base of the cornea and those of the antennula extend beyond for 
three-fourths of the length of the last segment. The terminal segment of the peduncle of the antenna 
is unarmed. The sides of the carapace are roughened by spiny granules. The chelipeds are small, 
the hand is narrow with a few rather large tubercular granules on the surface and four spines on the 
crest of the palm; the lower margin of the palm is concave at the base of the immovable finger; 
the closed fingers show a small hiatus. The upper surface of the carpus has three rows of spines,
