Related to P. phipsoni and flavimanus. 



$. Colour a uniform deep blackish green. Carapace smooth 

 above and on the frontal lobes, granular at the sides, a little longer 

 than 3rd aud 4th caudal segments. Terga almost entirely smooth, 

 the last with a few granules at the sides. Sterna smooth, the last 

 with four low crests. Tail short, about three times as long as the 

 carapace ; almost entirely smooth ; the superior and supero-lateral 

 keels at most weakly denticulate, sometimes quite smooth ; inferior 

 crests of 4th denticulate posteriorly ; upper side of 5th not granu- 

 lar except along the lateral keel ; vesicle scantily granular laterally 

 or smooth. C helot with hand very large, its inner edge shaped much 

 as in P. flavimanus and seaber, not so convex as in P. phipsoni; the 

 dorsal surface flatter than in these species, the external portion of 

 the upper surface not so vertical ; keel of underhand very strong, 

 stronger than in the species just mentioned and more convex ; upper 

 side studded with rounded, oval, or irregularly-shaped tubercles, 

 much like those of P. phipsoni; lobe of hand large; width of hand 

 almost as great as length of movable digit or of carapace ; immov- 

 able finger with smooth 

 crest. Tarsal armature mostly 

 5-4. Pectinal teeth 11-12 ; 

 base of pecten very narrow, 

 the teeth starting some dis- 

 tance from its point of attach- 

 ment. 



d* . Scarcely differing from 

 § in form of chelae and length 

 of tail, and thus easily re- 

 cognizable from the male of 

 P. phipsoni or bengalensis. Pec-
