Villiform teeth in the jaws, on the vomer and the pterygoid bones, 

 none on the palatines. The height of the body is one-fifth of the 

 total length, the length of the head nearly one-sixth. The front 

 part of the upper hp is rather thick, not protruding ; snout as long 

 as the orbit. The anterior dorsal commences somewhat nearer to 

 the snout than to the base of the caudal. Upper parts dark-coloured ; 

 a silvery band along the side.

Broad bands of villiform teeth in the jaws, on the vomer, the pala- 

 tine and pterygoid bones. The height of the body is contained five 

 times in the total length, the length of the head four times and a 

 half ; the latter is more than the distance between the origins of the 

 two dorsal fins ; snout much longer than the eye. Upper lip thick, 

 protruding anteriorly. The maxillary extends to, or beyond, the 

 vertical from the anterior margin of the eye. The interorbital space 

 is convex. The anterior dorsal commences midway between the 

 snout and the base of the caudal fin.

Description. — The body is moderately compressed, its greatest 

 depth being one -fifth of the total length ; its upper anterior profile 

 is very slightly convex, obliquely descending ; the length of the head 

 is contained four times and a half in the total. The interorbital 

 space is convex, its width being nearly one-third of the length of 

 the head. The snout is conical, twice as long as the eye, the dia- 

 meter of which is one-sixth of the length of the head. The upper lip 

 is thick, especially its front part, which projects beyond the lower 

 jaw. The cleft of the month is slightly oblique, and of moderate width.
