164 A. Alcock — Carcinological Fauna of India. [No. 1, 



The four teeth of the antero-lateral margin are blunt and rounded 

 the first two being very much worn. 



Chelipeds unequal — more so than in P. ungulatus : arm with two 

 or three coarse denticles on the anterior border, the posterior border 

 being rugose; upper and outer surface of wrist nodular; a certain part 

 of the upper, as well as of the inner and (more so) of the outer surfaces 

 of the hand nodular, but except in very young specimens, the nodules do 

 not extend beyond, and often not so far as, halfway along the hand, so 

 that the greater part of the hand is often smooth. 



Legs as in P. ungulatus, but the spinules are coarser and blunter. 



Colours in spirit — dark chestnut brown, sometimes mottled with 

 grey ; lingers blackish brown. 



In the Indian Museum is a single specimen from the Nicobars (in 

 addition to 21 from Australia, the South Seas, and Mauritius).

Regions of the carapace well defined and subdivided, by broad 

 and deepish grooves, into smooth, polished, convex but flat-topped 

 lobules : those of the branchio-hepatic regions are disposed transversely : 

 the antero-lateral sub-regions of the gastric area are not longitudinally 

 subdivided. 



Front bilobed, the outer angles of each lobe distinct but not very 

 prominent. 



The antero-lateral border is cut into four smooth lobes and is 

 rather shorter than the postero-lateral. 



The chelipeds are unequal : the arm has several sharp teeth on the 

 anterior border and several pearly tubercles on the distal end of the 

 posterior border, and the inner angle of the wrist is salient ; but the 

 surface of the chelipeds is smooth and polished. 



The most characteristic feature of the legs is the dense stiff fringe 

 of long greenish-yellow bristles that clothes the anterior border of the 

 last four joints, concealing the sharp spines with which these borders 

 are armed. 



Colours in spirit, body and legs green with brownish points, cheli- 

 peds brownish, fingers black. 



In the Indian Museum are 10 specimens, from the Andamans, 

 Mergui and Ceylon.
