and inner surface and a terminal ring of four spines, and the carpopodite has a 

 terminal ring of three spines ; the slender fingers, which are finely and evenly 

 toothed to the very tip, slightly exceed the elongate palm in length. 



The second, third, and fourth thoracic legs are relatively short, the second 

 pair barely, and the others less than, half the length of the chelipeds ; in all the 

 meropodite and carpopodite have the anterior edge spinate, and the dactylopodite 

 has the terminal claw but slightly curved and very much longer than the spines 

 along the posterior edge. 



The largest specimen, an egg-laden female, is 48 millim. in extreme length, 

 its chelipeds being 59 millim. long.

Distinguished from all its Indian congeners by the form of the dactyli of 

 the 2nd-4th legs, which are long and talon-like, having the posterior edge sharp 

 and entire. 



There are no epipodites on any of the thoracic legs. 



The carapace is quadrangular, its surface is coarsely granular, and it is 

 traversed fore and aft by a broken median carina which is surmounted by a few- 

 coarse spines : the frontal margin is hardly convex and is quite unarmed, 

 although below it, and between the eye and the antenna, is a spine : the parallel 

 lateral margins are acutely bilobed in front of the cervical groove, while behind 

 it they are denticulated : the posterior margin is multi-spinate : there is a pair 

 of coarse spines on the gastric region. 



The rostrum, which is about one-third the length of the carapace proper, 

 is depressed, acute, carinated, and simple. 



The abdominal terga are unarmed. 



The eyestalks are movable : the inner margin forms a small papilla upon 

 the summit of the cornea. The meropodite of the external maxillipeds has 

 three small teeth on its inner edge. The chelipeds in both sexes are equal to the 

 fully extended body, and are longer and stouter than the other legs : they are 

 unarmed, except for a pair of small spines at the distal end of the meropodite : 

 the fingers are not much shorter than the palm, and have the cutting edo-es 

 dentate only near the distal end. The 2nd-4th legs have the posterior border of 

 the meropodite serrated : in all the dactyli are remarkable for their great length
