Another band below eye over suborbital, crossing corner of mouth to chin, interrupted or broken into short stripes in its lower course, the bands of both sides not meeting. Two parallel bands on chin behind this band, broken into short stripes or rows of spots. A small dark blotch at origin of lateral line. Interorbital space or snout darker than rest of upper part of head. An indistinct darker transverse band below spinous and another below soft dorsal. Axil of pectoral deep black, bordered by a white line superiorly this ocellus covered by the base of the fin, except superiorly.

Eye 3.7-4, 1.2-1.4 in snout and 1.1-1.2 in scarcely convex interorbital space. Mouth somewhat oblique. Maxillary reaching slightly beyond vertical through nostril. Teeth conical or somewhat truncate, in two series, those of the inner row more slender. Preorbital and suborbital without scales. Posterior part of preorbital and anterior part of suborbital of the same depth, the suborbital rapidly decreasing in depth posteriorly, its lower border, which is strongly denticulated, therefore oblique. Three transverse rows of scales on preopercle, the inferior and posterior limbs with smaller deciduous scales. Posterior border of preopercle with numerous pointed denticulations. Scales on upper part of head reaching to a line connecting front borders of eyes. Dorsal spines increasing in size posteriorly, the last spine equal to snout and eye or somewhat shorter. The membranes between the spines slightly incised. Soft dorsal rather pointed, the longest rays equal to or somewhat more than head without snout. First anal spine less than half length of second, which is equal to postorbital part of head. Soft anal similar to soft dorsal.
