 narrow bands in both jaws, those of the outer series in the upper jaw 

 much enlarged and recurved in some specimens; eyes inserted high, the 

 interorbital space very narrow, about as wide as pupil ; diameter of orbit 

 much greater than snout, nearly \ of head. Gill opening 2^ in head, the 

 isthmus wide. Dorsals contiguous, the membrane of spinous dorsal
