Left cheliped slender, not reaching base of right dactylus : lower border 

 of merus serrated : upper surface of carpus with two longitudinal raised 

 rows of spinules : upper surface of hand with spinules or crescentic granules 

 in longitudinal series : the fingers are about as long as the palm, and the 

 fingers and palm combined are about as long as the carpus. 



2nd and 3rd legs moderately setose, surpassing the larger cheliped : 

 a spinule or two may be present on the anterior border of the carpus : the 

 dactyli are stout and nearly as long as the two preceding joints combined. 



Length of carapace 8 millim. 



The abdominal appendages (exclusive of the uropods) are four in number 

 in the male.

A variety from the south coast of Ceylon is characterized by the sculp- 

 ture of the outer surface of the palm and fingers of both chelipeds, where

Rostrum broad, triangular, but acute, reaching between the ophthalmic 

 scales and v^ell beyond the antennal angles of the carapace. 



Eyestalks comparatively slender, as long as, or slightly longer than, the 

 anterior border of the carapace, reaching nearly to middle of terminal joint 

 of antennular peduncles and nearly to end of antennal peduncles : eyes 

 little expanded ; ophthalmic scales acute, distant. 



Antennal acicle curved, reaching to end of eye, setose : flagellum more 

 than twice the length of the carapace, sparsely setose. 



Chelipeds and legs sparsely setose, the right cheliped vastly the larger. 

 The right cheliped is considerably more than twice the length of the 

 carapace : the merus is smooth and unarmed, and its crest-like inner lower 

 border is hirsute : the carpus, which is rather slender, is as long as the
