Description
Size: 30 cm.

Color: Brownish, darker above, lighter below, with traces of darker crossbars, more conspicuous in young specimens and often quite obsolete in adult ones. In young specimens there are often some black spots scattered over the body. Dorsal, anal and caudal with a white margin, the rest of the fins uniformly dark bluish black or lighter, striped with black. Ventrals hyaline, with a dusky streak. Pectorals black at the base, the black area bordered behind by a white band. Generally this band is followed by other ones distally, the bands being about their breadth apart and giving to the fin a striped appearance.

Body somewhat cylindrical anteriorly, compressed posteriorly. Height 5.5-6.5, 6.7-8.3 in length with caudal. Head 3.1-3.5, 4-4.3 in length with caudal. Head depressed, flat above, its upper profile sloping down in a nearly straight line or somewhat convex. Eye 5 (in specimen of 65 mm.)- 8 (in specimen of 142 mm.), in large specimens more than twice, in small specimens less than twice in the interorbital space, about 1-1.5 in snout. Tip of snout in the horizontal through middle or upper part of eye. Cleft of mouth oblique. Maxillary reaching to vertical through hindborder of eye, in small specimens not so far. Lower jaw somewhat prominent. A band of small teeth in the intermaxillaries. Teeth on the palatines and on the foremost part of the vomer forming a continuous biserial curved band, the outer teeth smaller, the inner teeth canines or caninoid. A band of small teeth, tapering laterally, in the lower jaw, the most interior row consisting of caninoid or canine teeth. About 5 rows of scales between eye and posterior border of praeoperculum and about 3 rows on operculum. Lateral line curving one scale downward behind the 11th-13th perforated scale. Dorsal beginning behind origin of pectorals and ending somewhat behind anal, its origin separated by 13-14 scales from tip of snout. Origin of anal about below 9th-11th dorsal ray. Pectorals somewhat more or less than postorbital part of head. Ventrals originating somewhat before origin of dorsal, about half as long as pectorals.
