BRACHYORA. RATHBUN. 107 



Relationship. Closely related to A. obesa* A. Milne 

 Edwards, which also has a broad-oval carapace with 

 numerous granules, similar areolations, and chelre of the 

 same form. In obesa, the lateral lobes are rounded, not at 

 all angular, and are not separated from the neighbouring 

 areoles, the granulation is very coarse especially on the 

 lateral thirds, and the posterior part is finely granulate, 

 not smooth as in inskipensis ; the posterior surface of the 

 merus of the last leg is granulous, not smooth ; the dactylus 

 of the cheliped has a row of spinules on the upper margin 

 instead of a single denticle.
