Carapace very broad, subpentagonal, branchial regions swollen.. Front 
four-toothed, the teeth blunt, separated from each other by narrow sinuses 
which are rounded at the bottom ; the two middle teeth are longer than the 
lateral ones, and the median sinus is deeper than the two lateral. The 
antero-lateral margin of the carapace is four-toothed, counting the promi- 
nent tooth at the external angle of the orbit; the posterior tooth of the 
series is the smallest. The upper margin of the orbit has three deep fissures 
defining two triangular teeth ; the lower margin of the orbit has two fissures 
enclosing a broad truncate tooth or lobe; there is also a broad and promi- 
nent lobe just below the inner orbital angle; above this lobe is a single 
tooth at the inner angle. The surface of the carapace is ornamented with 
granulated tubercles ; the parts between the tubercles are more finely granu- 
lated, and when viewed under a lens are found to be furnished with fine 
hairs. The chief tubercles are disposed as follows: one pair on the frontal 
region behind the margin; four in transverse row on the anterior part of 
the gastric area, and five on the posterior part of the same area arranged 
thus, :": (of these the posterior pair is the smallest); four in a transverse 
line on the cardiac region and one median behind the transverse series ; 
about six on each branchial area; six just anterior to the straight posterior 
margin of the carapace (three on each side). There are three small tubercles 
on each eye-stalk near the margin of the cornea. The chelipeds are small, 
slender, equal; the carpus tuberculate, the fingers as long as the hand 
proper, curved downward and inward, crossing at the tips, their prehensile 
edges finely denticulate in small specimens, nearly entire in larger ones. The 
second and third ambulatory limbs are very long, the second slightly larger 
than the third; their merus joints are granulated and costate above, and 
armed with a prominent spine at the anterior distal angle and a smaller one 
each side at the point of articulation with the carpus; this holds good of
