Diagnosis. — Rostrum almost horizontal. Supraorbital margin with- 

 out spine. Carapace wide, length without rostrum less than one and 

 a fourth times its width. 



Description. — Surface pubescent. Carapace rough with tubercles 

 and short spines; five median spines: two gastric, one genital, one 

 cardiac, and one above the posterior margin. Branchial region 

 surmounted by a spine, from which a row of smaller spines extends 

 obliquely to the inner angle; margin anteriorly spinous; a spine 

 near the antero-external angle, from which an irregular row extends 

 backward above the margin. Hepatic region with a spine near the 

 inner angle and one or two on the margin. Gastric region with a 

 stout marginal spine behind the postorbital spine, and a dorsal row of 

 spinules extending forward to each rostral horn. Many of these 

 spines may be replaced by tubercles; there are two tubercles side 

 by side on the genital and the intestinal regions. 



Rostral horns stout, tapering distally, contiguous, usually less than 

 one-third the length of postrostral portion of carapace, curving 

 downward toward the tips. The horns may have a buttonhole 

 interspace or may be slightly divergent in the terminal portion.
