Eye diameter 3.3-3.5 in head, 0.7-0.8 in snout and about equal to interorbital space. Breadth of body about 1.5 in its depth. Lower jaw projecting beyond the upper, a small skinny flap below symphysis. Teeth in one or two rows in jaws, no teeth on vomer and tongue. Dorsal fin originating anterior to a level from the anal fin origin. Head 1.4-1.6 in length of pectoral fin, pectoral fin scarcely reaching ventral fin origin. Base of dorsal fin 5.5-6.0 in standard length and 1.2-1.4 in head. Ventral fin equal to half length of head, its origin nearer to base of caudal fin than to gill opening.
