Bull. Mus. Comp. Zodl., XXIV. 187, 1893. 
Body and limbs clothed with short, scattered setae, Rostrum long, curved 
slightly upward, basal half furrowed longitudinally, with a row of short 
spines on each side of the furrow; infero-lateral edges of rostrum also fur- 
nished with small spines. Carapace quadrangular, anterior border forming a 
right angle with lateral border, both borders spinulose ; lateral border with 
an indentation at anterior boundary of anterior branchial lobe; a deep de- 
pression back of each anterior branchial lobe, and another across the anterior 
part of the cardiac region; the upper surface of the carapace is adorned with 
spinulose tubercles, and a median longitudinal row of more prominent spines 
runs along the gastric and cardiac regions; the anterior spine of the cardiac 
region overhangs the transverse depression, the posterior spine of the row 
springs from the hind rim of the carapace. There is a median hooked spine 
on the tergum of the second, third, fourth, and fifth abdominal segments, and 
many spiny tubercles irregularly disposed on these segments; the pleurz of 
the third to the sixth abdominal segments are narrow but blunt, those of the 
second to the fifth are costate. The ocular peduncle is movable, and devoid 
of a spine. The antenne are about as long as the body ; the basal joint has 
an inferior spine and a small external spine; the second joint also bears an 
external spine. The chelipeds are long and slender, all the joints from 
the ischium to the propodite are equipped with longitudinal rows of small 
spines; the chela is not broader than the basal part of the propodite, the 
fingers are straight, their prehensile edges: denticulate. The ambulatory 
appendages are spinulose. There are no epipodites on the five pairs of 
legs.

pace, 14 mm.; length of rostrum, 9 mm.; length of cheliped, 47.5 mm.
