Description
Size: 90 cm.

Color: Greenish or brownish above to almost black, white or silvery or light brown below. Upper parts with dark streaks and blotches, more or less arranged in oblique bars running forwards, lower parts with similar blotches and streaks, at right angles with those of the upper parts. In older specimens the upper parts are generally so dark as to make these markings obsolete. Lower surface of head and belly white, more or less freckled with brown. A dark band running from corner of mouth to suboperculum, sometimes very faint or absent in old specimens. Pectorals brownish to dark brown. Ventrals white, generally freckled with brown. Dorsal and anal generally freckled or streaked with brown and white. In young individuals there is sometimes a black ocellus at the end of the dorsal fin. Caudal brownish, with obsolete dark bands.

Cylindrical anteriorly, compressed posteriorly. Height 5-6, 6-7.3 in length with caudal. Head 3-3.2, 3.6 in length with caudal. Head depressed, its upper profile somewhat convex, interorbital space flat. Eye 5 (in specimen of 8o mm.)- 8 (in specimen of 340 mm.), twice (or less in small specimens) in interorbital space. Snout less than twice length of eye, its tip in the horizontal through middle of eye. Cleft of mouth oblique. Maxillary reaching behind eye, in young specimens not so far. Lower jaw slightly prominent. In the intermaxillaries bands of about 5 or 6 rows of teeth anteriorly, tapering posteriorly. These teeth are pointed and curved backwards, the postsymphysial ones longer and canine-like. In the mandibles the teeth are placed in several rows near the symphysis, in one row laterally. They are about equal to those in the intermaxillaries. In the lateral row there are on each side about 5 equidistant canines. Teeth on vomer and palatines slender, curved backwards, in several rows, those of the posterior row the longer. On the vomer they form a ^-shaped patch, on the palatines an elongate band. There are 6 or 7 rows of scales between the eye and the hindborder of the praeoperculum and 4 rows on the operculum. Lateral line with an abrupt curve downwards at about the 17th-20th perforated scale. Dorsal beginning behind base of pectorals and ending somewhat behind end of anal. Its origin separated by about 15 scales from tip of snout. Origin of anal about below 17th dorsal ray. Pectorals shorter than postorbital part of head. Ventrals originating about below origin of dorsal, equal to distance between hindborder of eye and hindborder of praeoperculum.
