Description
Size: 34 cm.

Color: Brownish-Grey above, silvery below on opercular spot, dorsal with an obscure margin, as also the caudal lobes, fins otherwise hyaline.

Oblong, compressed, dorsal profile convex from snout to caudal peduncle, ventral profile slightly oblique from chin to anal, thence ascending to caudal peduncles, which is rather robust, quadrangular and slightly less than diameter of eye at its root, height about 2.6 in length. Head 3.5-3.6 in length, slightly higher than long, its occiput elevated, the rostro-occipital profile ascending in a slightly convex trenchant line. Eye 3.5-4 in head, situated, somewhat obliquely, for its major part in anterior half of head, approximate to frontal profile, in adult a little shorter than blunt snout and interorbital space, the adipose eyelid forming a narrow rim, broadest above antero-superior angle, praeorbital posteriorly much lower than diameter of eye. Mouth slightly oblique, jaws about equal, the upper strongly protractile, maxillary with broad truncated hind border reaching below anterior part of eye. Nineteen gillrakers on lower part of first arch, finely tuberculated, the longest about the size of pupil, decreasing ventrally till about one fifth than length. Teeth in jaws in villiform bands, broadest anteriorly, some of the outer irregularly enlarged, conical but no canines, small teeth in a patch on vomer, in a band on palatines and tongue. Scales small, wanting on base of pectorals and on breast, the triangular naked area reaching behind ventrals. Cheeks, temporal region, upper part of operculum scaly, head and a median area reaching to dorsal spine, otherwise naked. Anterior part of lateral line moderately arched, becoming straight below about eighth dorsal ray, the straight portion slightly longer than the curved, with 36 to 40 armed scutes, gradually increasing in size, broadest below posterior dorsal rays and equaling 1/9 or 1/10 of height of body. Dorsal spines in a groove, slender, about 3 1/2 times in height of body. The seven anterior dorsal rays forming a falciform lobe, the second produced into a filament, reaching to caudal or on its upper lobe. The six anterior anal rays forming a falciform lobe, much lower than height of body. Caudal broadly forked, the upper lobe the longest. Pectorals rounded, falciform, much longer than head, ventrals originating behind pectorals, about twice shorter than head.
