Carapace smooth (non-granular), distantly pitted in the anterior 

 and lateral parts. Gastric region fairly well denned, except at the 

 cardiac end, its surface showing indistinct traces of lobulation : branchio- 

 hepatic regions with the surface a little uneven. 



Antero-lateral border with 7 (exclusive of the external orbital 

 angle) regular, even, nearly uniform, compressed, procurved teeth. 



Front as in EHsus dentatus, but with the angles a little sharper cut. 

 The edge of the orbit is trenchant, and near the outer angle are 3 not 

 very distinct suture-lines : the tooth at the inner angle of the lower 

 border of the orbit is prominent, and does not come into contact with 

 the eave of the orbit. 



Chelipeds in the adult male twice to twice-and-a-half, in the adult 

 female once-and-a-half to once-and-two-thirds the length of the cara- 

 pace : upper and lower edges of arm coarsely and unevenly granular, 

 much of the upper edge also hairy ; distal end of wrist with 4 or 5 teeth, 

 the inner two of which are long and large ; the hand has, along its 

 upper border, a double crest of strong teeth, continued in blunter form 

 along the finger, and on the outer surface of the hand there may be a 

 few pimple-like granules. 



In the legs, both the upper and lower edges — but most the upper 

 edge — of the merus, carpus and propodite are thickly fringed with long 

 bristles, as also is the lower edge of the dactylus ; the upper edge of the 

 merus has also a row of small spines, and the upper edge of the carpus, 

 propus and dactylus a double row of increasingly larger spines : the 

 lower edge also of the propus and dactylus is spiny. 



Colours in spirit : dull yellowish pink, fingers black. 



In the Indian Museum are a male and a female from the Singapore 

 Museum, and supposed to have come from Singapore. (Heller I.e. 

 records this species from the Nicobars).
