Snout as long as or rather shorter than eye, diameter of which is 3 (young) to 4I in length of head; inter- orbital width 12 to 16. Jaws equal anteriorly; maxillary not or only just reaching vertical from anterior margin of eye; cheeks, opercles, upper surface of head, and greater part of snout scaly in adult, but praeorbitals naked; 8 to 11 gill-rakers on lower part of anterior arch. Scales on body ctenoid; 54 to 60 in a longitudinal series from above base of pectoral to caudal; 34 to 47 (51) in upper lateral line, which ends below posterior part of dorsal; 30 to 42 in lower lateral line, which generally extends forward to or beyond level of tip of pectoral; lower lateral line usually without tubular scales in young. Dorsal VII-VIII, 31-34. Anal 31-34. Pectoral with 21 or 22 rays, | to | length of head, longer than pelvics, which reach vent or origin of anal in young, but not or scarcely as far as vent in adult. Caudal rounded or subtruncate; caudal peduncle about as long as deep. Upper part of head and body irregularly spotted and blotched, but only rarely with traces of darker cross-bars; young with irregular cross-bars, broken up into 3 or 4 series of alternating spots; usually a more distinct Y-shaped mark at base of caudal; dorsals, caudal, pectorals and sometimes the pelvics with series of dark spots forming bars; anal pale.
