Carapace moderately elongate, its antero-lateral border finely serrulate ; 

 there are some scattered vesiculous granules on the gastric (and cardiac) 

 region, but very few and faint transverse markings. 



Rostrum a slender spine, not so long as the ophthalmic scales : these 

 are large and have the antero-internal angle spinulose. 



Eyestalks stout, not two-thirds the length of the anterior border of the 

 carapace, reaching nearly to the middle third of the terminal joint of the 

 antennular and antennal peduncles : eyes large. 



The antennular are slightly longer than the antennal peduncles. The 

 antennal flagellum is shorter than the carapace and not much setose. The 

 antennal acicle is a simple spine, with the inner edge spinulose, and barely 

 reaches to the terminal joint of the peduncle. 



The left cheliped is vastly longer than the right, and in the adult male is 

 nearly 2^ times the length of the carapace. The joints are nude and closely 

 and crisply granulous, most finely so on the hand. The carpus is longer 

 than the merus and a little longer than the palm of the hand, its inner ed<^e 

 is very well defined and serrate. The palm of the hand is about half attain 

 as lonj; as broad ; its outer surface is longitudinally carinated near the middle 

 line, the carina gradually fading away before the finger-cleft is reached : its 

 upper border, like that of dactylus, is usually serrulate. The fixed finder is 

 deflexed, and the dactylus does not constitute quite half the total lencrth 

 of the hand. 



In the female and young male the length of the left cheliped, especially 

 of the wrist and palm, is much less than in the adult male, and in the 

 Indian Museum there is a series of specimens well illustrating this fact 

 which, as regards the young, was first noticed by de Man. 



The right cheliped is setose, especially as to the fingers : in the adult male 

 it does not reach to the middle of the left carpus. 



The 3rd right leg, which is a little longer than the and, hardly reaches 

 the base of the dactylus of the left cheliped. Both pairs of legs are almost 

 smooth as to the surface, but have the anterior edge of the carpus and 

 propodite spinulose and setose : the dactyli, which are longer than the propo- 

 dites, are plumose. Length of carapace about 10 millim.
