 The essential character of this genus is in the form of the 

 skull. Supraoccipital and temporal crests nowhere coalescent, 

 the interorbital area not swollen; frontal bone in the interorbital 

 area thin, concave in transverse section; temporal crest low, sepa- 

 rated from supraoccipital crest by a flattish area which extends 

 forward on each side of supraoccipital crest and to groove of 

 , premaxillary spines. Otherwise essentially as in A r c h o s a r- 

 g u s , the antrorse dorsal spine present, the second interhaemal 

 not modified. One species, the incisors deeply notched.
