Carapace about four-fiftbs as long as broad, the side.s distinctly 

 convergent posteriorly; besides tbe ohliqae markings on the laternl 

 parts of tbe epibranobial regions, there aio some lino tiMnsvorso mark- 

 ings on tbe post-frontal region. 



Front about tbree-fiftbs tbe greatest l)readtb of the carapace, its 

 free edge beaded, thin and prominent but bardly laminar, and slightly 

 sinuous. Orbits little oblique, their major diameter is a little more than 

 a tbird tbe width of tbe front: the inner angle of tbe lower border is 

 denticulate. 



Chelipeds unequal, tbe length of the larger one about 1^ times tbat 

 of tbe carapace : tbere are wrinkles or squaniiform markings on tbe 

 upper surface of tbe arm and wrist and — along with some vosiculons 

 granules — on tbe upper and lower borders of the band. The inner 

 border of the ischium is denticulate, the inner horder of the ni-m is 

 spinate and is expanded distally to form a laciniate lobe, and tbere is a 

 spine, which may be double, at the inner ungle of the wrist : the fingers 

 have blunt tips, and the dactylus is not veiy muoli longer than the 

 upper border of the palm. 



Of the legs the 1st pair is the smallest and the 3rd pair tbe longest 

 — about twice tbe length of the carapace : in all, the upper border 

 of the merus ends in a spine aud the lobe at the far end of the lower 

 border is spinate : in tbe last three pairs tbe greatest breadth of the 

 mei'us is half its length. 



The terminal segment of the male abdomen is simply triangular. 



In tbe Indian Museum are 56 specimens, from Karachi, Bombay, 

 the Orissa coast, tbe Ganges Delta, tbe Arakan coast, and the Anda- 

 mans. Tbe carapace of tbe largest specimen is 23| millim. long and 

 30 millim. broad.
