so that the external rnaxillipeds are visible beyond the front : very 

 densely covered, as are also the chelipeds, with bead-like granulations: 

 the regions delimited by shallow yet distinct furrows. The rostrum con- 

 sists of two divergent hollow lobes, the tips of which are curved slightly 

 outwards, beneath which the antennules are lodged, as in the other 

 S]3ecies of this genus : immediately behind the rostrum the carapace is 

 traversed from side to side by a deep groove. The antero-lateral margin 

 is interrupted by a deep notch, in front of which is a coarse blunt 

 hepatic tooth, while behind it is a stronger epibranchial tooth. The 

 lateral angle is also mnrked by a prominent granule. The posterior 

 margin is almost straight and bears three dentiform tubercles, of which 

 the median is hnrdly conspicuous. The hepa,tic regions are inflated, 

 as are also the sides of the gastric region. The intestinal region forms 

 a tumid boss, on the summit of which the granulations are obsolescent. 



The tips of both rami of the densely granular external rnaxillipeds 

 are strongly bent upwards, as in all the other species of this genus, 

 that. of the exognath ending in a large blister-like tubercle. [Some- 

 times also the outer angles of the buccal cavern, the tips of the frontal 

 teeth, and the edges of the orbit end in similar, but smaller, blister-like 

 swellings]. 



The chelipeds in the male are a little less than twice the length of 

 the carapace, and are stout : the fingers are stout, and are about as long 

 as the hand, which is rather more than two-fifths the length of the 

 carapace. Legs smooth : dactyli with a few hairs. 



The 3rd to the 5th abdominal terga are fused in the male, bnt are 

 independently recognizable, and the 6th has a terminal denticle — not 

 very conspicuous : in the female the 3rd to the 6th are fused. 



Male. Female. 



Length of carapace , 6'5 millim. 7'5 millim. 



Breadth of carapace 7-0 millim. O'O millim. 



Greatest span (of chelipeds) 240 millim. 26-5 millim. 



Besides being smaller, and having the chelipeds of slightly greater 

 relative length, the male differs from the female in being much more 

 sharply granular. 



Numerous males and egg-laden females, from different parts of 

 the Malabar Coast in 26-30 fathoms, from the North Maldive Atoll in 

 15-30 fms., and from Mergui in 40 fms. 



I have thought it justifiable to change the name of this species from 

 granvlosa to pustulilabris, as Miers, ' Challenger ' Brachyura (1886) p. 317 

 has already used the very similar name granulata for a species belonging 

 to tliis genus as here defined.
