to side, almost flat fore and aft behind the line of long hairs that marks 

 the frontal declivity : its surface, when denuded, is quite smooth : only 

 the branchial or " cervical " groove and the cardiac region are distinctly 

 marked. 



Lateral borders of carapace entire, except that there may be a tiny 

 denticle behind the branchial groove. 



Outer orbital angle dentiform. Sub-orbital lobe dentiform, de- 

 flexed. 



Chelipeds and legs comparatively slender, the chelipeds shorter 

 and hardly stouter than the legs. Two acute tubercles on the outer 

 surface of the wrist. 



Fourth (last) pair of legs little slenderer and about as long as 

 either of the first two pair, ending in a slender claw-like dactylus to 

 which a spimile at the end of the propodite is opposed. 



Third pair of legs not less stout than, but only about half the 

 length of, the first two pair ; ending in a claw-like dactylus. 



Length of carapace of an adult female 7 millim., greatest breadth — 

 in front of the branchial groove — 6 millim. 



Five specimens, representing adults of both sexes, from off Ceylon 

 34 fathoms, and from the Pedro Shoal (off Malabar coast) 20 fathoms.

 p. 406, pi. xxxviii, figs. 7-9. 



The front is entire and subacute, without any trace of lateral teeth. 

 No supra-orbital tooth. Outer orbital angle poorly marked. The lower 

 orbital margin is formed simply by the antennal peduncle. Chelipeds 

 without any teeth or tubercles. The carpus of the third pair of legs 

 has a prominent lobe at its distal end, anteriorly. Dactylus of fourth 

 (last) pair of legs straight : its propodite with 3 spinules at its far end. 



Loc. Tuticorin.

All parts, except the dactyli and tips of the fingers covered with a 

 close velvet-like tomentum. 



Carapace not elongate in the adult, dorsally quite flat, sub- 

 pentagonal in outline. 



Front cut into 3 teeth, of which the middle one is on a very much 

 lower plane (and is much smaller) than the others.
