36. Randallia glans, n. sp. 



Carapace globular, usually in the male smooth and polished to the 

 naked eye though closely punctate-gfanular under the lens, in the 

 female densely covered with vesicular granules that are often visible 

 without any magnificn,tion : all its borders smooth and full, and except 

 for a broad and shallow notch in the antero-lateral border, between the 

 branchial and hepatic regions, its regions are not in any way defined. 



Front narrow, broadly bidentate, the tips of the teeth somewhat 

 produced and bent outwards : its base is separated from the rest of the 

 carapace by an indistinct groove. 



External maxillipeds smooth and polished to the naked eye in the 

 male, somewhat more granular in the female — just like the carapace. 



Chelipeds stout : in the male a little less than twice the length of the 

 carapace, everywhere very densely granular, the granules being vesicular 

 and being plainly visible without a lens on the arm at any rate : fingers 

 stout, as long as the hand, which is between | and f the length of the 

 carapace. Legs smooth : dactyli with a few hairs. 



In the male the 3rd-5th abdominal terga are fused but are inde- 

 pendently recognizable, and the 6th has a strong terminal denticle ; in 

 the female the 3rd-6th are fused. 



The carapace of the adult male is 6 millim. in either diameter, that 

 of the ovigerous female is 7'5 millim. long and 8 millim. broad. 



Andaman Sea, about 50 fms. 



This species is closely related to B. pustuUIabris. 



37. Randallia lamellidentata, Wood-Mason.

 vestigator' Crustacea, pi. v. figs. 5, 5a, 55 ; Alcock, Ann. Slag. Nat. Hist. May, 1894, 

 p. 404. 



Carapace rhomboidal with the angles rounded off — subcircular; 

 its surface behind the front covered with unequal-sized rather scattered 

 pustulous tubercles ; its regions well defined by grooves of some depth. 



Front bluntly bidentate. On the antero-lateral margin are three 

 broad lamelliform teeth, the front one of which is on the pterygosto- 

 mian ridge (which as usual forms the front part of the antero-lateral 

 margin), and there is a fourth similar tooth at the junction of the 

 antero-lateral and postero-lateral margins. The postero-lateral margins 

 are full and the pustulous tubercles extend on to them. 



The short posterior margin is elegantly bilobed, with a few j^early 

 granules round the lobes, and is overhung by the tip of the horizontal 

 spine in which the intestinal region culminates. 



The ventral surface of the carapace, the thoracic sterna, abdominal
