166 Carcinological Fauna of India. 
Legs slender, the first 3 pairs 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 Laéreillia pen- 
nifera, and is as follows :—

Latreillopsis bispinosa, Henderson, Challenger Anomura, p. 22, pl. ii. fig. 3. f. 
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 rostruam—pro- 
jecting obliquely forwards from their prominent outer angle, and with 
one or two small spinules on their under surface. 
Hyestalks 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. 
Chelipeds 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 the rostrum. In the
