Chlorodius lasvissimus, Dana, Proc. Ac. Nat. Sci. Phila. 1852, p. 80, and U. S. 

 Expl. Exp. Crust, pt. 1. p. 215, pi. xii. figs. 4a-g. 



Carapace hexagonal, a little tumid, its surface perfectly smooth 

 without trace of regions or areolae. 



First lobe of antero-lateral border almost obsolete, last tooth very 

 small, the third tooth much the largest and most prominent. 



Anterior edge of arm without a spine. 



Last three joints of the legs with a. few scattered long fine 

 bristles — no hair. 



Fingers very strongly arched, a character which — as Dana has 

 noticed — at once distinguishes this little species from the young of 

 Chlorodius niger, which it otherwise closely resembles. 



Colours in spirit, white, fingers brown. 



In the Indian Museum are 9 specimens, from the Andamans and 

 Ceylon, (and 1 from Mauritius).

 the carapace. Front distinctly bilobed, with the outer angle of each 

 lobe forming a distinct little lobule ; its breadth is about a third the 

 greatest breadth of the carapace. Orbital margin with 2 grooves above 

 and one at the outer angle : eyes on short thick stalks. 



Antero-lateral borders cut into four lobes or teeth : postero- lateral 

 border nearly equal in length to the antero-lateral.
