the surrounding parts; its anterior margin is denticulated, with a larger spine 
on each side. The lateral margins of the carapace are armed with ten or 
eleven spines, the one on the antero-lateral angle being the longest. The 
second abdominal segment is ornamented with a transverse row of eight small 
spines. The other abdominal segments are normally destitute of spines, 
but in a few of the many specimens before me there are two or four small 
spinules on the third segment. The pleure of the third, fourth, and sixth 
abdominal segments are acute, the rest blunt. The eyes are large, and are 
provided with rather long cilia on the edge of the cornea. The basal joint 
of the antenna is armed with a long and sharp spine which reaches forward 
beyond the eyes; the second joint also has a long spine on each side. The 
chelipeds are long and hairy; the merus, carpus, and basal part of the pro- 
podus are spiny, the fingers long, slender, the cutting edges straight and 
finely spinulose, The ambulatory appendages are setose, the upper and lower 
edges of the merus are spinulose and there is, moreover, a row of spinules on 
the outer surface, this external line of spinules being best developed on the 
proximal end of the segment. The carpus is armed with small spines on the 
upper margin, and one spine on the distal end of the lower margin; the penul- 
timate and terminal joints are unarmed.

In this species the sete on the ridges of the thorax and abdomen and on the 
legs are resplendent with iridescent hues. The rostrum is long, triangular in 
cross section, the upper surface scabrous, the lateral margins armed with two to 
four spines which are generally placed unsymmetrically on the two sides. The 
supra-ocular spines are short. There is a transverse line of spinules back of 
the base of the rostrum, the two which lie on either side of the median line 
being larger than the others. Seven marginal spines on each side of the 
carapace, the ones at the antero-lateral angles the largest. There are no spines 
on the abdominal segments. The abdominal pleure are acute. The basal 
joint of the antenna has a plate-like expansion, but is not spinose ; the second 
joint is furnished with an external spine. Chelipeds very long, squamose, and 
clothed with silky sete; the merus has a row of spines on the upper margin, 
another on the inner side, and a row of smaller ones on the outer side ; the 
carpus is provided with three or four spinules at the distal end; the chela 
is slender, the outer finger flattened, ribbed above, the outer edge rather 
convex and expanded toward the base; cutting edges of fingers finely denticu-
