 Rather compressed, the breadth of the body going about 

 1,5 in its height. Height 5.7 — 6.5, 7 — 8 in length with caudal. 

 Head a little more than 4, 5.3 — 5.5 in length with caudal. 

 Eye 3, less than postorbital part of head, which is equal to 

 the somewhat concave interorbital space. Snout somewhat less 

 than diameter of eye. Teeth comparatively rather well deve- 

 loped, simple, conical, pointed, in about three rows in the 

 jaws; a few only on each side on the palatines. Origin of 

 dorsal opposite to that of anal, separated by 28 — 32 scales 

 from occiput; its distance from first rudimentary caudal ray 

 a little more or less than length of head. Pectorals reaching 

 to end of dorsal or not so far or even surpassing it. Ventrals 

 longer than head, reaching to about middle of anal or farther, 

 their origin a little nearer to base of caudal than to hindborder 

 of praeoperculum. Caudal deeply forked. Colour of preserved 

 specimens brownish above, silvery below. Pectorals blackish, 

 especially in the posterior half, with an oblique hyaline band 

 across the lower half and a reddish patch and a white hind- 

 margin near the axil. Other fins yellowish, caudal dusky.
