Size: 36 cm.

Color: In young ones brown, belly lighter, with four longitudinal narrow white bands, the first beginning in the median line on nape, through basal part of spinous dorsal, ascending on soft dorsal. The second from snout, above eye to end of caudal, running through the upper part of that fin, the third from below eye, through axil of pectoral to end of caudal, running through the lower part of that fin, the fourth below pectoral to anal. Pectorals black, bordered above and below by white. In older specimens new bands arise, one between the first and second, beginning in the median line on snout splitting before the origin of the first, sometimes united with it, running below spinous dorsal, ascending on soft dorsal below the first. Another band between the second and the third, from snout through eye to middle of median caudal rays. In this stage the second and third band converge on the caudal towards the median line, almost touching each other at the end of the median caudal rays. Between the just described median band on the caudal, and each of these bands an oblique band, the upper one parallel to the upper, the lower one parallel to the lower band, both therefore convergent. The median band on the body on the body may split again in its anterior part and the bands may be connected in different ways on the head. Spinous dorsal with a dark brown base and a dark brown margin leaving a broad white band between them, which is the posterior part of the first band of the young. Anal longitudinally striped dark brown and white. The light borders of the pectorals form two bands, converging posteriorly, in the adults, and parallel to them new bands arise, connected through a transverse white band not far from base of fin. With age the white on the pectorals increasing, leaving some dark spots only and disappearing in old specimens (radja). In very large specimens the dark inter spaces between the bands on the dorsal, anal and caudal are dissolved into rows of spots (lessoni).

Dorsal profile gently rounded, descending abruptly above eye, the head being very blunt. Height 2.7-2.8, 3.3-3.5 in length with caudal. Head 3.1-3.3, 4-4.2 in length with caudal. Eye 3.2-4, 1.3-1.5 in snout. Mouth slightly oblique. Lips thick. Maxillary reaching to below front border of eye. Three rows of teeth in the jaws, the outer row consisting of large pointed teeth. Preoperculum rectangular, serrate behind. Dorsal scarcely notched. First dorsal spine half length of second, which is shorter than third. Fourth to sixth of equal length, as long as post orbital part of head. Following spines slightly decreasing in length posteriorly, the last spine as long as or slightly shorter than the second spine. Soft dorsal acutely rounded, higher than spinous part. First anal spine minute, second somewhat longer than third and equal to post orbital part of head and half eye together. Soft anal acutely rounded, as deep as soft dorsal. Pectorals half length of snout shorter than head, ventrals somewhat longer, their spine slightly more than post orbital part of head. Caudal somewhat rounded in young, truncate or emarginate in old specimens.

Remarks: Values in above description denote proportions.
