region take on a spiny character. The rostrum is nearly horizontal, triangu- 
lar in cross-section, the margins serrate ; the anterior border of the carapace 
is convex between the eyes and the antenne, but has no spine at this point ; 
lateral border four-toothed, one of the teeth lying at the antero-lateral angle, 
two on the hepatic region, and one on the edge of the branchial region 
behind the cervical suture ; the posterior border is delicately festooned, but 
not armed with spines. The abdomen is spineless, its surface punctate, an- 
terior half of the pleur of the second segment tuberculate, all the pleura 
rounded. The eye has a transverse granulated tubercle running over the 
cornea from the inner side. The antennz are very slender and do not 
exceed the carapace in length. The chelipeds are moderately robust, the 
merus tuberculate and armed with a row of short spines along the upper 
edge; the carpus spino-tuberculate, with two longitudial furrows on the 
outer side ; hand almost smooth on the inner side, outer side and superior 
surface roughened with low tubercles ; fingers curved slightly upward, spoon- 
shaped at the denticulate and setose tips. Ambulatory appendages: meri 
flattened, tuberculate, upper edge produced to a spimose carina; the carpi 
have three denticulate ridges; propodites scabrous, with an irregular row of 
spines on under side; the dactyli have black tips and are finely spinulose on 
their posterior edges.

The carapace of this species is moderately convex, with a deep trans- 
verse depression across the anterior part of the cardiac area. The rostrum 
is long, slightly upturned, and armed near the middle with a pair of lateral 
spines. The gastric area has three pairs of spines, the anterior pair the 
largest. There is one spine on each anterior branchial lobe. The cardiac 
area bears two or three pairs of spines. The lateral margins of the carapace 
carry from six to eight spines each, and there is a longitudinal series of small 
spines within the margin on the branchial area. A small spine is situated 
on the anterior margin between the eye and the antenna. The posterior
