In young ones two margaritaceous strips, running from above eye and from hind border of eye, parallel to each other, to base of soft dorsal. A third much broader band from snout, below eye to end of dorsal, where it ends in a margaritaceous patch. This band bordered above and below with a narrow black stripe. There is also a median narrow margaritaceous stripe, running from inter orbital space to base of dorsal. In older specimens the two superior stripes are relatively much shorter and run upwards in a curved line in the direction of the spinous dorsal, which they do not reach. The light band, still bordered by black lines, also curves upwards and ends below the anterior soft dorsal rays. It does not reach anymore the margaritaceous patch, which is still visible below the end of the soft dorsal. Fins hyaline or yellowish, an elongate black patch, bordered below with white, in upper part of dorsal, between penultimate or last spine and the anterior four or five rays. Membrane between anal spines and first anal ray black, that between first and second ray white.

Height 2.6-2.8, 3.2-3.6 in length with caudal. Head 2.9-3.3, 3.7-4.1 in length with caudal. Eye 2.8-3.3, somewhat more than Snout and than slightly convex inter orbital space. scales on head beginning before eyes, reaching on snout to a line connecting anterior nostrils. Mouth somewhat oblique, maxillary smooth, reaching slightly beyond vertical through front border of eye. Slender curved teeth in narrow bands in the jaws, the outer series enlarged. Preoperculum with 4 transverse rows of scales and one or two rows more on inferior limb, which is scaly. Posterior border of preoperculum scalloped, the edge rounded, Strongly denticulate. Suborbital spine strong, reaching to below hind border of pupil or somewhat farther. Two to three smaller spine below it. First dorsal spine three fourths of second or somewhat longer. Third slightly longer than second. Fourth to seventh spine sub equal, as long as post orbital part of head eye together. Soft dorsal higher than spinous part, rounded. First anal spine somewhat less than half length of second, which is somewhat longer than third and as longest dorsal spine. Soft anal rounded, as high as or somewhat higher than soft dorsal. Pectorals and ventrals, the first ray of which is produced, sub equal, not quite as long as head. Caudal forked.
