Head broader than deep, snout elongate, less than twice as long as the 

 mouth, broad and broadly rounded from the eyes to the end. Nostrils little 

 nearer to the mouth than to the end of the snout. Mouth greatly arched, 

 length two thirds of the width; a short labial fold on each jaw, upper little 

 longer. Teeth in || rows, median upper erect and hardly smaller, lateral teeth 

 with cusps inclined toward the angles of the mouth over a notch on the outer 

 edge. Eye large, pupil vertical, hind border of orbit equidistant from first gill 

 cleft and end of snout. Inner angle of pectoral slightly produced, rounded, 

 reaching a vertical from the origin of the first dorsal. Hinder angles of dorsals 

 and anal produced, acuminate. First dorsal about as large as the pectorals, 

 origin above their inner angles, end hardly reaching above origins of ventrals. 

 Second dorsal smaller and farther back than the anal, middle of its base above 

 end of anal base. Tail about two sevenths of the total length; lower lobe of 

 caudal well developed. 



Back brown, olivaceous to greyish, hind margins of pectorals white. Lower
