Abdomen smooth, the second tergum transversely bicarinate, the third 

 transversely grooved. 



Eyes quite immovable, without spine or spinule. Two large spines on the 

 inner edge of the merus of the external maxillipeds. 



Chelipeds in the female (male unknown) slender, unequal, the larger one 

 slightly longer, the smaller one very slightly shorter, than the fully extended 

 body ; two rows of spines on the arm, both series continued, but much less 

 conspicuously, along the wrist, but not along the hand ; the fingers meet through- 

 out their length. No epipodite on any of the thoracic legs. 



Legs long, the first three pairs being scarcely shorter than the fully extended 

 body : their merus has a few spinules at the proximal end of its anterior 

 border, and both its borders terminate acutely ; their carpus is carinate and ends 

 in a spine ; their dactylus is more than half the length of the propodite and has 

 its posterior border spinulate. 



A single female from off the Travancore coast, 430 fathoms. 



The length of the carapace is 21*5 millim., of the larger cheliped 24 millim., 

 of the smaller cheliped 21 millim.

Carapace convex, broader behind than in front, covered as far as the tip of 

 the rostrum with transverse, squamiform, ciliated sculpture, spineless, the regions 

 inconspicuous. 



Rostrum of moderate length, simple, bi'oadly and acutely triangular, dorsally 

 carinate. A blunt tooth on the anterior border of the carapace ; lateral borders 

 cut into two blunt lobes exclusive of the subacute antero-lateral angle, but these 

 lobes may be almost indistinguishable ; posterior border smooth. 



Abdomen unarmed, the second to the fifth terga transversely grooved ; the 

 fifth and sixth terga, the telson and the outer half of the blades of the 

 swimmeret, and the margins of the pleura with a fine, rather irregular, squami- 

 form sculpturing. 



Eyes freely movable, spineless, more or less retractile beneath the rostrum. 

 Two very inconspicuous teeth on the inner edge of the merus of the 

 external maxillipeds. 



Chelipeds and legs covered with ciliated squamiform sculpturing, unarmed. 



Chelipeds moderately stout, equal in both sexes, much shorter than the 



fully extended body, not half a dactylus longer than the legs ; palm and fingers
