Records of the Indian Museum. [Vol. XXIV, 



the articulation is less clearly sinuous (text-fig. 6ia). In both 

 sexes the stouter ramus of the outer flagellum is shorter than the 

 peduncle. In its distal third the antennal scale is rather more 

 narrowed than in P. grandis and its outer margin more strongly 

 concave; it is from 4'5 to nearly 5-5 times as long as wide (text- 

 fig. 616). 



The third maxilliped possess a small arthrobranch ; the an- 

 tepenultimate segment bears from 1 to 4 spines on its outer edge 

 and the exopod reaches about to its end. The ultimate segment 

 is about three-quarters the length of the antepenultimate.

. The first peraeopods (text-fig. 62a) reach beyond the antennal 

 scale by about half the length of the chela. The carpus is from 

 one-ninth to one-twelfth longer than the merus and is from 

 7 to 7*5 times as long as its distal breadth and from i"2 to 14 

 times as long as the chela. The fingers are equal to or a little 

 shorter than the palm and are unarmed. 



The second peraeopods are equal. In males they extend 

 beyond the antennal scale by the length of the carpus and chela. 

 In none of the specimens I have seen do the legs present the rugose 

 appearance described by Paulson. In males (text-fig. 62&) the 

 merus is from 6 to 7 times as long as broad, with the usual spine
