Somewhat compressed, the breadth of the body going 1.4 

 in its height. Height about 5, 6.6 in length with caudal. Head 

 4.1 — 4.3, 5.3 — 5.8 in length with caudal. Eye 3, 1.3 in post- 

 orbital part of head and somewhat less than slightly concave 

 interorbital space. Snout somewhat less than eye. No chin- 

 barbel. Teeth comparatively large, simple, conical, pointed, in 

 bands of about three rows in the jaws and in a small ovate 

 patch on each side on the palatines. No vomerine teeth. Origin 

 of anal opposite to 5th or 6th dorsal ray. Origin of dorsal 

 separated by about 30 scales from occiput. Pectorals reaching 

 to end of dorsal or farther. Ventrals longer than head, extending 

 to middle of anal, their origin somewhat nearer to caudal 

 than to hindmargin of eye. Caudal deeply forked. Blackish 

 above, silvery below. Pectorals black, narrowly bordered with 

 white below and behind. Hinder two thirds of dorsal with a 

 large black patch. Ventrals and caudal mottled with dusky.

Somewhat compressed, the breadth of the body going 1.3 

 in its height. Height 5 — 5.3, 6.'i^ — 6.J in length with caudal. 

 Head 4.3, about 5.5 in length with caudal. Eye 3 or nearly 

 so; 1.4 in postorbital part of head and not much less than 

 interorbital space. Teeth tricuspid in both jaws (at least partly), 

 small, in several rows. On each side on the palatines a long 

 narrow patch of teeth. Origin of anal opposite to 5'h dorsal 

 ray. Origin of dorsal separated by 28 — 30 scales from occiput. 

 Pectorals reaching to middle of dorsal fin or a little farther. 

 Ventrals longer than head, reaching to end of anal, their 

 origin nearer to base of caudal than to branchial opening, 

 sometimes even by as much as postorbital part of head. Caudal 

 deeply forked. Colour of preserved specimens brownish above,
