entire — but by a deep emargination of the prolonged foliaceons oper- 

 cular process of the first maxillipeds. 



Chelipeds fairly massive, unequal in both sexes ; fingers of good 

 length, pointed. 



Abdomen of male with all seven segments distinct.

Carapace broad, transversely oval, with a shiny frosted surface due 

 to extremely close fine granulation, the granules becoming vesiculous 

 and plainly visible to the naked eye near the frontal, orbital, and lateral 

 borders. 



The orbits are marked off by a fine groove, a short shallow 

 A-shaped groove bisects the front and ends on the anterior part of the 

 gastric region, and a fine sinuous crease passes from the interval 

 between the third and fourth tooth of the antero-lateral margin inwards 

 towards the gastric region ; otherwise the surface of the carapace is 

 unbroken. 



Front nearly two-fifths the greatest breadth of the carapace, almost 

 straight, with a fine double edge, the upper rim of which runs on to the 

 orbit while the lower turns obliquely downwards to rest on the basal 

 antennal joint, — both rims finely beaded. 



The antero-lateral borders are cut into four thin sharp-edged teeth, 

 the first three of which are somewhat angular, while the last is elegantly 

 procurved : the edges of all are finely beaded. 



The orbits are large and almost subtubular : the finely-beaded edge 

 is entire, and the inner angle of the lower border is bluntly prominent : 

 quite inside the orbit, where the cornea comes into contact, is an elegant 

 fringe of eye-lashes. 



The upper and outer surfaces of the wrists and hands are finely 

 frosted : the inner angle of the wrist has the form of a sharp spine. 



The last three joints of the legs are more or less covered with a 

 harsh tomentum, thickest along the upper surface. 



Colours in spirit : carapace dark purple above, dark greenish below, 

 legs greenish, chelipeds greenish daubed with red and purple, fingers 

 red. In very old spirit specimens the carapace and chelipeds are of a 

 rosy madder. 



In the Indian Museum are 4 specimens from the Andamans and 

 one from an unrecorded (Indian) locality.
