Diagnosis. — Crest of carpus of ambulatory legs two-horned or 

 crescentic; no crest on last pair. Inferior orbital margin trilobed, a 

 small lobe between two large ones. 



Description. — Similar to the preceding. Carapace wider in pro- 

 portion to its length; surface rugose or granidous. Front thick as in 

 ceratopus, but doubled by a padlike crest which runs parallel and 

 close to the marginal crest. Superior margin of orbit without fissure; 

 inferior margin with a small tooth or tubercle between the two large 

 lobes. Antero-lateral margin with three pointed teeth, directed 

 more outward than forward. Two large tubercles on subhepatic 

 region; one is visible from above between the first antero-lateral 

 tooth and the exorbital lobe, the other is below the outer end of that 

 lobe and is partially concealed by it; the subhepatic tubercles form 

 a continuous line with the antero-lateral teeth (but not the exorbital 

 lobe) and lead up to the outer lobe of the inferior orbital margin. 



Chelipeds covered with coarse conical tubercles each of which 

 forms a center for a rosette of short coarse hairs. Ambulatory legs
