harsh coat of short bristles with longer bristles interspersed, the latter 

 being most numerous on the legs. 



Carapace about f as long as broad, deflexed anteriorly, nearly flat 

 in the posterior two-thirds, the regions fairly distinctly delimited, the 

 surface rather profusely studded with little pits, from which the tufts 

 of bristles arise ; some granules near the antero-lateral borders and on 

 the front part of the gastric region. 



Front cut into two lobes, each of which is again subdivided by a 

 deep triangular gap into a large square-cut internal lobe and an acute 

 triangular external lobule. 



Orbital margin granular: there are two gaps in the upper margin, 

 but the inner one is narrow and indistinct ; there is also a small gap just 

 below the outer angle of the orbit, which is not very prominent. 



Antero-lateral margin not much shorter than the postero-lateral, 

 cut into three somewhat granular spiniform teeth. No tooth below the 

 outer angle of the orbit. 



Antennary flagellum not quite a third the length of the carapace, 

 not fringed with hairs, though there may be one or two at its base. 



Chelipeds very unequal : upper and outer surfaces of both wrists 

 and hands and bases of dactyli covered with granules or small pearly 

 tubercles, which are larger and more numerous and more prominent on 

 the hands than on the wrists ; sometimes a small patch of granules on 

 inner surface of hands : inner angle of wrists strongly pronounced and 

 dentiform. 



Legs stout, the longest pair are about two-thirds again as long as 

 the carapace. 



Colours in spirit : carapace yellow copiously overspread with brick- 

 red, chelipeds and legs yellow blotched and sometimes banded with terra- 

 cotta-red. 



In the Indian Museum are 7 fine specimens from the Andamans 

 (besides one from Samoa).
