52. Hoploxanthus hextii, n. sp. 



The whole of the carapace, legs, and outer surface of chelipeds is 

 covered with a dense, darkish, extremely short, velvety or branny 

 pubescence. 



Carapace hexagonal, moderately broad, moderately convex, the 

 regions well denned, tumid, their convexities granular. 



Front prominent beyond the orbits and separated from them by a 

 notch, square-cut, bilaminar. 



Anterolateral border thin sharp, cut into four triangular laciniate 

 teeth, the last of which — in the female but not in the male — is an 

 acute salient spine. 



The edges of all the teeth, of the front, and of the orbit are finely 

 granular. 



The postero-lateral border is elegantly granular and quite straight : 

 dorsal to it the wall of the carapace forms a distinct postero-lateral 

 facet, sharply marked off from the general surface of the carapace. 



Chelipeds a little unequal in both sexes : wrist with a small some- 

 what cristiform expansion at the outer angle and a tooth at the inner 

 angle : upper surface of hand with two or three longitudinal raised 

 sculptured lines, the innermost of which consists of a blunt cristiform 

 lobule followed by one or two blunt denticles, tlie outer one or two 

 being simply crenulate and granular; the outer surface of the smaller 

 hand is everywhere granular, that of the larger hand is granular in 

 part — in both cases some of the granules form sb'ghtly-raised longi- 

 tudinal lines. 



Legs long, slender. 



Colours in spirit yellowish brown. 



Carapace of male JO millim. long, 13 millim. broad; of female, 

 11 millim. long, 17 millim. broad. 



In the Indian Museum are 3 specimens from the east coast of India 

 and 2 from the Nicobars. 



53. Hoploxanthus cultripes, n. sp. 



Carapace hexagonal : the three gastric subregions (lateral and post- 

 medial), the cardiac region, and two (smaller) median epibranchial regions 

 stand out as very prominent granular bosses, and the convexity of the 

 lateral epibranchial spine, and the postero-lateral border and its 

 neighbourhood are granular, — otherwise the carapace is quite smooth. 



Front prominent, sublaminar, with a curved convex finely granular 

 edge, faintly notched in the middle line and hardly separated from the 

 supra-orbital angles.
