Size: 15-19 cm.

Color: Upper body is rosy and silvery below.

Rostro-frontal profile rather convex, snout rather blunt. Height of head, measured in vertical through hind border of preoperculum, half length of operculum shorter than length. Height 3.3-3.4, 4.2-4.3 in length with caudal. Head 3.2-3.3, 4.1-4.2 in length with caudal. eye 3.6, slightly less than snout. Inter orbital space nearly flat, 1.2 in eye. Mouth oblique, maxillary reaching to below front border of eye. Lower jaw slightly included. A few rows of pointed teeth in the upper jaw, tapering into one row laterally, with an outer row of larger teeth, consisting of six curved canines anteriorly and about 20 much smaller teeth laterally. A row of conical, pointed teeth in the lower jaw, with an irregular inner row of smaller teeth near symphysis. Suborbital as high as half vertical diameter of eye, its angle rounded, its hind border forming a more or less straight line, which, when produced, reaches the dorsal profile 8 to 9 scales before origin of dorsal. Preoperculum with 3 transverse rows of scales, its naked limb half as deep as scaly part. Hind border of preoperculum finely denticulate. Scales beginning on head with an indistinct supra-temporal band of about 3 scales, the median point of which reaches anteriorly to above middle of eyes. Dorsal spines flexible and pungent, increasing in length from the first to the last, the different between these two not more than half diameter of pupil. Tenth spine as long as snout and half eye together. Membrane between dorsal spine not emarginate. Soft dorsal somewhat higher than spinous part, pointed behind, the seventh ray being the longest and equal to snout and eye together. First anal spine more than half length of second, which is somewhat shorter than third and equal to diameter of eye. Soft anal deeper than spinous part, pointed behind, its lower border rounded. Pectorals almost as long as head. Ventrals, with the first ray produced into a long filament, which reaches to anal, equal to length of head. Caudal deeply forked, the lobes pointed. Least height of caudal peduncle almost twice in its length. Lower edge of eye lies above a line from tip of snout to upper base of pectoral fin, suborbital with straight lower margin and rounded posterior margin. Dorsal fin origin about 2-5 scale rows from imaginary line projected upwards from posterior edge of suborbital to dorsal profile. Caudal fin with the upper lobe produced into a short, reddish filament. In life, head with oblique yellow stripe from beneath eye to middle of upper jaw and another from anterior of eye to near tip of snout. Axillary scale present. Dorsal spines (total): 10, Dorsal soft rays (total): 9, Anal spines: 3, Anal soft rays: 7.
