A darkish streak, bordered by lighter, from hindborder of eye to angle of prae-operculum. Dorsal and caudal more or less dusky, other fins hyaline.

Dorsal profile sloping gently from dorsal to snout. Height 2.4-2.6, 3.2-3.9 in length with caudal. Head 2.5, 3.2-3.3 in length with caudal. Eye 3.3 in head, two thirds of eye-diameter apart, shorter than snout. Mouth oblique, maxillary reaching to below middle of eye. Two vertical rows of scales on praeoperculum, which is denticulated along its hind and lower border. Praeopercular ridge denticulated. Lower orbital rim with strong denticulations, praeorbital smooth or with a few denticulations posteriorly. Conical teeth in several rows in jaws, in two rows on vomer and palatines. Origin of first dorsal somewhat behind that of ventrals, first spine small, second one much stronger than the others, longer than third one and equal to eye and snout, following spines decreasing rapidly in size, the hindborder of the fin therefore vertical when the spines are erected. Spine of second dorsal equal to third one of first dorsal and to postorbital part of head, longest soft rays almost equal to head without snout. Origin of anal below third soft ray of dorsal. First anal spine minute, second one equal to that of second dorsal. Soft anal rays as long as those of dorsal. Caudal feebly incised, the lobes rounded. Pectorals and ventrals subequal, as long as head without snout or a little shorter. Least height of caudal peduncle almost 1.5 in its length, somewhat more than postorbital part of head.
Dorsal spines (total): 7-7, Dorsal soft rays (total): 9-9, Anal spines: 2, Anal soft rays: 8. Juveniles have intense dark markings on a light background . Adults dusky
