Diagnosis. Front narrow, but wider than long. Carapace coarsely 

 granulate. Fingers of large cheliped of male thin and flat. 



Description. Regions of carapace marked by deep furrows; sur- 

 face covered with fine granules mixed with coarse granules or 

 tubercles, most striking on branchial and cardiac regions; surface of 

 front smooth. Front tapering anteriorly, subtruncate, a little 

 rounded at extremity. Lateral margins nearly straight and longi- 

 tudinal or a little curved for a short distance behind antero-lateral 

 angles, then curving rather abruptly inward and backward; margins 

 formed of alternately large and small granules. Upper margin of 

 orbit very sinuous, marked with small, distant granules; lower
