Carapace nearly £ as long as broad, of a mulberry -like appearance, 

 owing to its entire surface being covered with rough tubercles in the 

 closest possible contact with one another by the base. Each individual 

 tubercle again has a mulberry-like appearance, since it is formed of a 

 number of facetted granules confluent by their bases. 



The lobulation of the carapace is very complete, but is almost lost 

 in the polygonal mosaic of tubercles. 



The 4-lobulation of the antero-lateral borders is inconspicuous. 



The postero-lateral borders are shorter than the antero-lateral, and 

 are markedly concave. 



Front sharply bilobed, the lobes projecting far beyond the well 

 pronounced orbital angle. Orbital margin with three closed sutures. 



The exposed surfaces of the chelipeds are covered with the same 

 strong many-facetted tubercles as the carapace ; but on the legs the 

 tubercles have sharper points and are many of them spiny, especially 

 those on the dactyli. 



The abdominal terga and the greater part of the sternum are 

 covered with a mosaic of smooth-worn tubercles : the under wall of the 

 carapace, as far as the epimeral suture, is granular. 



Fingers short, blunt pointed, hardly hollow at tip. 



Basal antennal joint prolonged between front and orbit almost to 

 the inner angle of the orbit, very much as in Carpilius etc. 



Colour in spirit light reddish brown, fingers black with white tips : 

 in life the colour is uniform purplish black. 



In the Indian Museum are 10 specimens from the Persian Gulf, 

 Karachi, Pedro Shoal, Ceylon, Ganjam Coast, Mergui, and Malacca 

 (besides 14 specimens from Australia and Hongkong),

Not very easily distinguishable from Actxa granulata at first sight, 

 but the following difference is constant : — 



(!) the carapace is shorter and broader, its length being only about 

 two-thirds its breadth : 



(2) the tubercles of the carapace and chelipeds are much smoother
