carapace : three round laminiform 

 lobes on the posterior margin of the 



carapace R. ebumea. 



ii. Chelipeds short and stout, less than 

 twice the length of the carapace : 

 posterior margin of carapace differ- 

 ing from that of all the other species 

 in being quite smooth R. glans. 



34. Randallia Janata, n. sp. 



The whole of the body and its appendages covered with a close, 

 short, light-coloured, velvety pubescence. 



Carapace circular, globulai*, with all the regions well defined by 

 grooves ; its surface covered, beneath the pubescence, with rather dis- 

 tant pustulous granules. Behind the front all the margins of the 

 denuded carapace are armed with blunt dentiform tubercles or granules. 

 There is a not very distinct notch between the hepatic and branchial 

 regions. 



The front has an almost straight edge, and although it is for 

 the genns rather prominent, the ends of the external maxillipeds 

 can be seen beyond it in a dorsal view. 



The orbits are so emarginate above as to afford little concealment 

 to the retracted eye, which is rather large. 



The antennules fold obliquely, their basal joint forming a close- 

 fitting operculum to the antennulary fossae. 



The chelipeds are similar in both sexes, being stout and about half 

 again as long as the carapace : the hand is very stout, is not much longer 

 than broad, and is about one-third the length of the carapace : the 

 fingers are stout and are about three-fourths the length of the hand. 

 The legs are stoutish. 



In both sexes all seven abdominal terga are plainly and indepen- 

 dently recognizable though not all independently movable : in the 

 female (even in the ovigerous adult) the abdomen is somewhat narrow. 



In the adult male the carapace is 7 millim. long and 6 - 5 millim. 

 broad, in the adult female it is 8*5 millim. in both diameters. 



Andaman Sea usually at over 30 fathoms.
