There are some soft bristles on tlie cliellpeds, and a few on the 

 legs, and some very sliort and inconspicuous hairs on the carapace. 



Colours in life, pink. 



The carapace of a large egg-laden female is 19 millim. long and 

 15 millim. broad. 



This species has frequently been taken in the Laccadive Sea and 

 in the sea to the north of the Laccadives at depths ranging from 740 to 

 931 fathoms, on soft bottoms. 



In the Indian Museum are more than 30 specimens representing 

 both sexes, both adult and in young stages.

 p. G : Alcock, Investigator, Deep-Sea Brachyura, p. 15, pi. 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 sometimes followed by a row of spinules. Subhepatic and sub- 

 orbital 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. 



Ohelipeds slender, reaching not far beyond the end of the carpus of 

 the first pair of legs, the arm and wrist not stouter than the meropod- 

 ites of the first three pair of legs ; spinate and spinulate as in the pre- 

 ceding 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
