196 Carciuological Fauna of India. 



terga (in the male) and external maxillipeds are all granular, the gra- 

 nules above the base of the chelipeds being enlarged and pearly. 



The chelipeds in the male are about two-thirds as long again as the 

 carapace, and are massive and granular : at the distal end of the outer 

 edge of the somewhat trigonal arm the granules are enlarged and 

 almost spiniform, as are also one or two at the distal end of the outer 

 surface of the wrist. The hand is not much longer than broad and 

 hardly one-third the length of the carapace ; its outer edge is in the form 

 of a remarkably thin and deep crest : the fingers are stout and rather 

 longer than the hand, their outer (non-opposed) edges are cristiform. 



The legs are granular, the granules on the dorsum of the pro- 

 podites carpopodites and distal end of the meropodites being spini- 

 form, as also on the outer surface of the ischium and merus of the last 

 pair : the dactyli are hairy. 



The 3rd— 6th abdominal terga of the male are fused bub are all" 

 very distinctly and independently recognizable, the 6th has a termi- 

 nal denticle. 



The largest male, dredged in the Andaman Sea at 350 fins., has 

 the carapace between 16 and 17 millim. long and 18 niillirn. broad 

 (without spines).

Carapace subcircular, subspherical ; covered with unequally large 

 pustulous tubercles the surface of which, like the surface between them, 

 is finely and closely granular under the lens ; all the regions are well 

 defined by broad grooves. 



The front is narrow and broadly bidentate. The lateral margins 

 are full and inflated, and carry in the adult a series of tubercles, in the 

 young a series of blunt spines : in the antero-lateral margin, between the 

 hepatic and branchial regions, is a conspicuous notch, which corresponds 

 with a groove or depression in the pterygostomian face of the carapace. 



The short posterior border has a spine or dentiform lobe at either 

 end, and is overhung by the long spine in which the tumid intestinal 

 region culminates. 



The whole under surface is densely granular in the young male, 

 but in the female the fused 4th-6th abdominal terga and the inner half 

 of the ischium of the external maxillipeds are smooth. 



The chelipeds in the adult female and young male (adult male 

 unknown) are twice the length of the carapace and are everywhere
