Carapace longer than broad, shaped much as in Homola : frontal region with 

 three sharp slender spines, the middle one — which is the shortest and is slightly 

 deflexed — being the rostrum, the other two — which are about a third the length 

 of the carapace and are slightly up-tilted — being placed above the bases of the 

 eyestalks. Gastric region tumid, with a tubercle posteriorly and a curved 

 transverse row of tiny tubercles anteriorly. Cardiac region small, tumid, 

 culminating in two tubercles placed side by side or confiueut. Branchial regions 

 with an irregular surface, and with one or two tiny spinules on the side wall. 

 Hepatic regions standing out like a pair of little wings, with two spines — the 

 foremost of which is nearly as long as the rostrum — projecting obliquely for- 

 wards from their prominent outer angle, and with one or two small spinules on 

 their under surface. Eyestalks nearly as long as the supraocular spines. 

 Antennal peduncle about as long as the eyes and eyestalks combined, the 

 flagellum more than three-fourths the length of the carapace. 



Chelipeds and legs slender, cyhndrical, practically smooth, except for a spine 

 at the far end of the anterior (extensor) border of the merus. The chelipeds in 

 the male are just over twice, in the female less than twice, the length of the 

 carapace without the rostrum. In the female they are hardly stouter than the 

 legs ; but in the male they are distinctly stouter, especially as regards the palm, 

 which is club-shaped : the palm is much longer than the fingers. 



The first three pairs of ambulatory legs increase in length, gradually but 

 slightly, from before backwards, the 3rd pair being between 4 and 4- times the 

 leno'th of the carapace : the dactyli are long and curved. The fourth (last) pair 

 of legs are a little longer than the male chelipeds : their last two joints are short, 

 and the dactylus folds down, like a knife-blade, on a double row of spines along 

 the posterior border of the propodite. 



In both sexes the last abdominal tergum is shaped like a spearhead, and the 

 2nd, 3rd, 4th and Gth terga have an acute tubercle in the middle line. 



The carapace of an egg-laden female is 8 millim. long. 



Colours in spirit yellow, the fingers and eyes dark brown.
