Eye 3.5 to 4.3, high above horizontal through gape of mouth, more or less than twice in broadly convex inter orbital space, much less than blunt snout. Anterior nostril oval, twice longer than round posterior. Preorbital slightly denticulate, hind and lower border of preoperculum weakly serrate, its angular spine grooved or slightly triquetrous, even in adult of very variable length (sexually?), 2.4-4 in head, at most reaching to below middle of base of pectoral, interoperculum and suboperculum entire. Scales on trunk moderate, rounded, with several auxiliaries forming a basal rim, subequal, horizontally in somewhat irregular series, the vertical series more regular arranged, on head velvety, minute on chest and median fins, lateral line arched, complete. Dorsal spines graduate, soft dorsal acute, in adult the five or six anterior rays sometimes acutely produced, the line arched, complete. Dorsal spines graduate, soft dorsal acute, in adult the five or six anterior rays sometimes acutely produced, the hind border vertical, likewise the soft anal, which is otherwise obliquely rounded, third anal spine equal to or slightly shorter than head. Pectorals acutely rounded, equal to or somewhat shorter than head, ventrals with the first ray prolonged, equal to or conspicuously longer than head, reaching anal, their spine about as long as head without snout. Caudal bluntly rounded, least height of its peduncle about twice in head.
