This species lias frequently been taken in the Laccadive Sea and in the sea 

 to the north of the Laccadives at depths ranging from 740 to 931 fms., on soft 

 bottoms. 



In the Indian Museum are more than 30 specimens representing both sexes 

 adult and in young stages. 



HypSOphrys longlpes, Alcock and Anderson. Plate I, fig. 1. 



Rostrum deeply bifid. Linea anomurica distinct. 



Four large spines on the anterior border of the carapace — two close together 

 at the base of the rostrum, one at either orbital angle. 



Lateral borders of dorsum of carapace well defined, spinulate; the ridge 

 on the side-wall of the carapace that defines the branchial regions anteriorly 

 is also spinulate. A row of spines on the hepatic region, the largest of which 

 is on the lateral border of the carapace and has a spine dorsad of it. 



Gastric region obscurely subdivided, each lateral subregion is armed with 

 5 or 6 large spines, while on the median region there is a central spine some- 

 times followed by a row of spinules. Subhepatic and suborbital region with 

 numerous large spines, one of which is " antennal." 



Eyes well pigmented. Antennal flagella more than twice the length of the 

 carapace. 



Rows of spinules on the exposed surface of the ischium merus and exognath 

 of the external maxillipeds, and a row on the basal joint of the antennules. 



Chelipeds slender, reaching not far beyond the end of the carpus of the first pair 

 of legs, the arm and wrist not stouter than the meropodites of the first 3 pair of 

 legs ; spinate and spinulate as in the preceding species ; fingers as long as the hand. 



The second and third pair of legs, which are slightly longer than the first 

 and three times as long as the fourth, are four times the length of the carapace. 

 In the first three pair of legs the merus is compressed and has its anterior 

 border spinate and its posterior borders spinulate, the posterior border of the 

 propodite carries a few distant articulating spinelets, and the dactylus — which is 

 about two-thirds the length of the preceding joint — has a close comb of arti- 

 culating spines along its posterior border. 



The fourth (dorsal) pair, which are extremely slender, have the posterior 

 border of the merus strongly spinate : the propodite is several times longer than 

 the minute dactylus. 



The terminal joint of the male abdomen ends acutely. 



Hairs and bristles are sparsely present just as in the preceding species. 



The carapace of a large egg-laden female is 38 millim. long and 30 milUm. 

 broad.
