the anal fin.

Body compressed, oblong-ovate, the upper and lower profiles sub-

anterior dorsal rays, then slopes gradually and reaches the caudal. Nostrils 
placed a little nearer the eye than the tip of snout, each with two simple 
oval openings, the anterior being largest and placed almost vertically on the 
snout. Mandible long, narrow, reaching to below the anterior 1 of the eye. 
Premaxillary teeth in dense villiform bands with an outer series which

Origin of the dorsal fin above the anterior quarter of the pectoral. 
The first spine is very short, one-third the diameter of the eye; those 
following increase in length backwards. :
