A row of four brown spots in median line of sides, the first behind head, the second behind pectorals, the third between end of dorsal and anal, and the fourth at base of caudal. These spots are not always distinct. A dark brown patch between first and second dorsal spines. spinous dorsal with a narrow brown submarginal longitudinal band and traces of a second band below it. Anal with a reddish brown broad longitudinal band, getting obsolete posteriorly. Pectorals hyaine. Ventrals brownish. Caudal with a few brown transverse bands posteriorly. All spines and rays, excepting those of pectorals, green. Upper lip with two brownish spots on either side just behind tip. Spinous dorsal greenish with a narrow submarginal band and a dark brown spot between first and second spines. Caudal brownish with some brown transverse bars. Pectoral hyaline. Ventral greenish brown.

Height 2.3-2.6, 2.8-3.2 in length with caudal. Head 2.6-2.7, 3.2-3.3 in length with caudal. Height of head equal to its length. Eye 5-5.5, 1.2-1.4 in somewhat convex inter orbital space and 1.6-1.8 in snout, the profile of which is concave. Mouth small, very oblique. Maxillary ending far before eyes. A single row of conical teeth in the jaws, with two canines anteriorly in each jaw. Teeth white. Preopercle smooth, with two transverse rows of scales, leaving only the posterior edge naked. Scales on upper part of head beginning above middle of eyes. Six rows of scales before dorsal. Dorsal spines gently increasing in length posteriorly, the last about equal to post orbital part of head, not shorter than anterior rays. The membranes between the spines incised and lobate in young. Soft dorsal rounded. Origin of anal below 8th or 9 th dorsal spines. First anal spine shortest, third longest, equal to snout or somewhat longer. Soft anal rounded. Dorsal and anal with a well developed scaly sheath at base. Pectorals rounded, equal to snout and eye, as long as ventrals in young, in adults the ventrals are much pointed and one eye diameter longer than pectorals. Two rows of scales on preopercle, hind edge naked. Dorsal spines increasing gradually in length posteriorly, the last as long as twice eye diameter. Pectoral slightly longer than postorbital length of head. Ventral slightly shorter than pectoral.
