edge : some longish hairs scattered along the upper border of the last 

 four, and also along the ventral (posterior) borders of the last two joints. 



Colours in spirit : yellowish white, fingers blackish-brown. In well 

 preserved spirit specimens the legs are banded with bluish green, and 

 large confluent bluish green blotches occur on the carapace. 



In the Indian Museum are J 5 specimens, from the Andamans f 

 Madras coast and Ceylon, (besides 6 from parts outside India).

Surface of carapace, except for the characteristic deep cut areola- 

 tion, quite smooth to the naked eye. Deep well-cut grooves separate 

 the fronto-orbital region, define the gastric region, and subdivide the 

 branchio-hepatic regions into 3 or 4 lobules ; and the gastric region is 

 divided into 3 sub-regions by fine but well-cut lines. 



Front bilobed, the outer angle of each lobe being well defined and 

 separated from the supra-orbital margin by a notch and groove. The 

 3 grooves of the orbital border are distinct. 



Antero-lateral border cut into 4 teeth, of which the last two are 

 procurved and spine-like. 



Chelipeds markedly unequal, the larger one more than twice the 

 length of the carapace : the arm in both is not quite concealed by the 

 carapace, is devoid of hair, and has the distal end of the upper border 

 spinate : in the smaller cheliped, the upper and outer surfaces of the 

 wrist and the upper and a large part of the outer surface of the hand 

 are studded with sharp spine-like tubercles; but in the larger cheliped 

 the tubercles are larger, less numerous, and are low and worn, not 

 spine-like: the fingers are pointed, not hollowed at tip, and in the 

 smaller cheliped are fluted, the ridges of the dactylus having a few 

 sharpish tubercles at the basal end. 



The upper edge of the meropodites of the legs is spiny, with a few 

 long fine bristles : the upper borders of the next two joints have each 

 two rows of spines and a good many long bristles, the carpus having 

 also a third row of sharp granules : the dactylus is granular and bristly, 

 and the lower edge also of the propodite has some bristles. 



Colours of well-preserved spirit specimens : purplish brown, the 

 purplish tinge very distinct on the chelipeds, the last 3 joints of the 

 legs are greenish.
