Legs slender, the first three pair very long ; the fourth pair reduced 

 in length, and subchelate. 



The abdomen in both sexes consists of 7 separate segments. 



The branchial formula is exactly the same as that of Latreillia pen^

 Latreillopsis hispinosa, Henderson, Challenger Anomura, p. 22, pi. ii. fig. 3. ? . 



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 eye-stalks. 



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 confluent. 

 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 — pro- 

 jecting obliquely forwards from their prominent outer angle, and with 

 one or two small spinules on their under surface. 



Eyestalks nearly as long as the supra-ocular spines. Antennal 

 peduncle about as long as the eyes and eye-stalks combined, the 

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



C helipads and legs slender, cylindrical, 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 thie rostrum. In the
