Upper surface of head more or less blackish as also ventral border of lower jaw.

Compressed, its greatest breadth about 1 1/2 times in its height. Height 4.7 to 6.4 times in total length, according to size. Head 4.3 to 4.9 in total length, pointed, its upper surface flattened but slightly convex in interorbital part, wherefrom it is decidedly declivous to point of snout. Mouth comparatively large, the jaws equal, the maxillary reaching to below pupil or nearly so. Snout much shorter than eye, more or less than 4 times in head. Eye 2.5-2.7, about equal to postorbital part of head and to interorbital space. Origin of first dorsal opposite to 15th, by exception to 16th scale, midway or somewhat nearer to root of caudal than to frontborder of eye, its vertical much nearer to anal than to base of ventrals, and about 2 scales behind anus. Origin of second dorsal opposite to 24th to 26th, usually to 25th scale and to about end of anterior third of anal, its distance from origin of first dorsal contained 1.3 to 1.6 in head. Both fins are separated by 6 to 8, usually 7 interdorsal scales. Distance of origin of second dorsal from caudal equal to or longer than head. Length of caudal peduncle, measured dorsally, shorter than distance from point of snout to hindborder of eye, about twice in length of head. Pectorals 5.3 to 6.5 in total length, their tips reaching 8th, 9th or usually 10th scale. Anus opposite to 12th or 14th, usually to 13th scale, situated between tips of ventrals or immediately behind their end, about 2 scales before vertical through first dorsal.
