Carapace transversely oval, convex fore and aft, slightly so from 

 side to side ; its length about T 9 T its breadth ; its surface granular and 

 somewhat tuberculous anteriorly, the tubercles being almost squami- 

 form and fringed with short stubbly hair. The gastric region and its 

 three subregions are very faintly indicated : the branchial regions are 

 traversed by a low, sinuous, finely granular ridge. 



The front, which is somewhat less than a third the greatest 

 breadth of the carapace, has a rather indistinctly double edge and is 

 cut into four lobes. There is a distinct gap in the orbital margin just 

 below the outer orbital angle. 



The antero-lateral border is deeply cut into five very thin sharp- 

 edged teeth. 



The exposed surfaces of the arms wrists and hands are finely reti- 

 culate-rugulose (most strongly marked on the hands) the reticulating* 

 wrinkles being covered with a very short stubbly or scurfy tomentum. 

 Similar reticulating lines and patches of the same stubbly or scurfy 

 growth also closely cover the surfaces of the leg joints. 



Colours in spirit, dull earthly brown or yellowish, the carapace and 

 chelipeds commonly mottled or marbled. 



In the Indian Museum are 5 specimens, from Mergui and the 

 Andamans (besides 2 from the South Sea Is.).

Differs from Ozius only in the form of the orbits. The upper and 

 lower inner angles of the orbit are in contact, so as to close the orbit 

 and to completely exclude the antennary flagellum. 



I do not think this character is of generic importance, and I agree 

 with Kossmann that the type of this genus should be included with 

 Ozius.
