(fifth) granular tubercle exists just behind the orbit : the posterolateral 

 borders are very distinctly concave, and are much shorter than the 

 anterolateral borders. 



The outer surface of the wrist, when denuded, has much the same 

 sculpture as the carapace. An oblique patch of the lower outer surface 

 of the hand is smooth and polished and quite devoid of hair, as are the 

 fingers except the basal half of the upper edge of the dactylus. The 

 upper outer surface of the hand, when denuded, shows about six 

 longitudinal lines of granules, the three upper of which are a little 

 diffuse. 



The fingers are compressed and trenchant, resembling shears: 

 the cutting edge of the dactylus is entire, but that of the thumb has 

 three incisiform teeth of unequal size at the base. In marked contrast 

 to all other parts, the fingers are smooth and polished. 



In the Indian Museum are 3 specimens from the Andamans. 



It appears to me to be quite consistent at present to separate this 

 species from Actsea while uniting Actseodes with that genus, for the good 

 reason that iu this case there are no known transitional forms.

Carapace broad, strongly convex in both directions, the regions 

 well delimited and subdivided into very numerous convex lentil-like 

 lobules ; its antero-lateral borders strongly arched, crenulate ; its postero- 

 lateral borders concave, very short. 



Front deflexed, two-lobed — the lobes being conspicuous and pro- 

 minent. 



Orbital margin thickened and smoothly crenulate ; a strong suture 

 line in the lower margin. Eyes on short thick sub-globular stalks. 



Antennules folding obliquely owing to the large size of the basal 

 joint : interantennulary septum broad. 



Basal antennal joint hardly touching the front, the next joint and 

 the very short flagellum wedged in the gap between the orbit and the 

 front. 



Merus of the external maxillipeds with a wide and deep notch in the 

 anterior margin. 



The chelipeds are unequal in both sexes ; the fingers are blunt- 

 pointed and hollowed-out at tip.
