---

Description
Size: 21-26 cm.

Color: Upper body pinkish, silvery white below.

Profile of head gently sloping from snout to nape. The height of the head, measures in the vertical through hind border of preoperculum, almost equal to length of head. Height 2.9-3.2, 3.7-4 in length with caudal. Head 3.1-3.2, 3.9-4 in length with caudal. Eye 3.4-4.4, 1.4-1.6 in snout and equal to flat inter orbital space. Mouth somewhat oblique, maxillary reaching to below front border of eye or of pupil. Jaws equal. Narrow bands of small pointed teeth in the anterior part of the jaws, laterally a row of about 20-30 caninoid ones on each side, continued anteriorly into an outer row of about 6 distant canines. Suborbital rectangular, its hind border forming a more or less straight line, which, when produced the dorsal profile about 5 scales before origin of dorsal, its depth about equal to eye. Naked limb of preoperculum almost twice in that of the scaly part. Hind border of preoperculum denticulate or somewhat crenulate only. Scales beginning on head slightly before hind border of eyes with a rather well-defined temporal band of 4 rows of scales. Dorsal spines slender and flexible, but pungent. The first spine about three fourths of the second. Second to sixth or fourth to seventh spine sub equal, as long as post orbital part of head or somewhat shorter. Tenth spine equal in length to second one. Soft dorsal slightly higher than spinous part, pointed posteriorly. Anal spines slender, first less than half length of second, which equals diameter of eye. Third spine slightly longer than second, but less than soft rays. Soft anal rounded anteriorly, pointed behind. Pectorals one diameter of eye or of pupil shorter than head. Ventrals with the first ray produced, somewhat shorter than pectorals. Caudal deeply forked, the lobes pointed. Least height of caudal peduncle 1.6 to nearly twice in its length. Suborbital spine absent. Preopercle with 3 transverse scale rows. Pectoral fins long, reaching to or beyond level of anus. Pelvic fins very long, reaching to or just beyond level of anus. A line drawn up from posterior edge of suborbital reaching the dorsal profile at about 2 to 6 scale rows before origin of dorsal fin. Upper lobe of caudal fin slightly longer than lower, tipped with yellow. Females predominate at small sizes, males at larger sizes. Axillary scale present. Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 7.
