finely granular. The hand is subcylindrical and clongafe, being half 

 as long as the carapace ; the fingers are stout and about as long as the 

 hand, they are finely denticulate, with enlarged denticles at regular 

 distant intervals. 



The legs are stoutish and, to the naked eye, smooth : the dactyl i 

 are fringed with hairs. 



In the (young) male the 3rd-6th abdominal terga are fused but 

 without any obliteration of sutures : in the adult female the 4th-6th. 

 are fused and the sutures obliterated. 



Carapace of an adult female about 31 millira. in either diameter. 



Log. Andaman Sea, 240-220 fms., and 250 fms., Laccadive Sea, 

 406 fms. 



In the young tlie carapace is quite spherical, with its edges spiny 

 and its surface closely and crisply granular — the young, in short, has 

 a very strong general resemblance to the adalt of B. pustuUlahris. 



In the adult female the brood-pouch communicates with the 

 brancliial chambers on either side by means of a foramen, as in Parilia. 



39. RandalUa ehiirnea, n. sp. 



Carapace subcircular, convex, subspherical, perfectly smooth to 

 the naked eye though closely covered with vesicular granules under the 

 lens ; its regions, except the intestinal, hardly defined. 



The front is narrow, and is broadly bidentate ; the edge of the 

 buccal cavern is more prominent beyond it than in any of the other 

 species. Between the convex subhepatic border and the branchial 

 border is a broad notch : near the middle of the branchial border is a 

 rounded deflexed tooth : the antero-lateral margin from the front to 

 this tooth is finely denticulate. 



The fissures in the outer wall of the orbit are very distinct. 



The posterior margin is elegantly three lobed, the lateral lobes 

 being broad and semicircular, the middle lobe being narrower: all 

 three are laminar. 



The external maxillipeds are granular and pubescent distally. 



The chelipeds are longer and more slender than in any of the other 

 species, being a little more than 2| times the length of the carapace: 

 they are perfectly smooth to the naked eye though closely granular 

 under the lens, the granules on the arms being vesicular. The hands 

 are subcylindrical and about two-thirds the length of the carapace : the 

 fingers are stout and between f and | the length of the hand, their 

 opposed edges are finely denticulate, with enlarged denticles at distant 

 regular intervals. Legs smooth, the dactyli with a few fine hairs at 

 tip only.
