Scales on body cycloid; 54 to 68 in a longitudinal series from above base of pectoral to caudal; 34 to 49 in upper lateral line, which ends below posterior part of dorsal; 6 to 17 in lower lateral line. Dorsal III-VII, 35-40. Anal 27-31. Pectoral with 17 or 18 rays, from less than § (large specimens) to f length of head, longer than pelvics, which do not or scarcely reach the vent. Caudal subtruncate or a little rounded in adult and half-grown specimens, emarginate in young; caudal peduncle nearly as long as deep. Coloration varying from dark greenish-black to a pale orange-yellow, with or without spots and markings; usually one or two oblique dark bars across cheek, sometimes broken up into spots; head sometimes with pale spots enclosed in dark rings; spots on body and dorsal fin sometimes large and tessellated, more often small and scattered, never very distinct and rarely uniting to form longitudinal stripes; dorsal and anal usually with pale edges, and sometimes with dark submarginal bands; pectorals and caudal more or less dusky; pelvics paler.
