The Icngtli of the head is contained thrice and two-thirds or four 

 times in the distance between the gill-opening and the vent. Snout 

 slender, produced into a joint ; cleft of the mouth very wide, half as 

 long as the head. Eye of moderate size, two-sevenths of the length 

 of the snout, situated in the anterior third of the length of the head. 

 Teeth pointed, fixed, unequal in size, those of the intermaxillary 

 and maxillary biscrial, the others uniserial. The intermaxillary 

 teeth and anterior of the mandible and those of the vomer are 

 canine teeth. Gill-openings rather wide. Vertical fins moderately 

 developed ; the distance between the base of the pectoral and origin 

 of the dorsal is twice or rather more than twice the length of the 

 pectoral, the length of which is about one-sixth of that of the head.

 mouth very wide, nearly two-fifths of the length of the head. Eye 

 small, two-fifths of the length of the snout, situated in the anterior
