Diagnosis. — Palm elongate, proximally narrow, the upper part 

 turned inward to form an upper surface. Front very shallow and 

 broad. Eyebrow obliquely inclined. Hand slightly roughened. 



Description. — Carapace widest behind the antero-lateral angles; 

 greatest width about one and one-half times greatest length. Surface 

 very convex antero-posteriorly, slightly so transversely; antero- 

 lateral regions punctate, punctae filled with hair. H-form depres- 

 sion deep ; as is also the semicircular depression which begins behind 

 the orbit and is continued along the antero-lateral margin. 



Front at its base one-third of the f ronto-orbital width ; rounding 

 strongly downward; lower edge very broad and subtruncate. Upper 

 margin of orbit sinuous and almost transverse; antero-lateral angle 

 directed forward, very broadlj' obtuse. Lateral margins and lower
