stricted and preventral region with distinct median keel its whole 

 length. Caudal peduncle compressed, about long as deep. 



Head well compressed, profiles alike, though lower little more 

 inclined, flattened sides slightly constricted below. Snout well 

 protruded, rather conic, end rounded in profile, length | its basal 

 width. Eye large, rounded, anterior or centre about first third in

 slightly expanded terminally, and almost reaches gill-opening. 

 Maxillary teeth simple, conic, all slightly sloping forward, uniform,
