Diagnosis

Diagnosis: body elongate, moderately deep and compressed; dorsal profile of head almost straight, ending in a pointed snout; eyes relatively small; upper jaw slender and rounded posteriorly, ending below or beyond posterior eye margin; 2 dorsal fins, 1st with 7 spines with only their bases connected by a membrane, 2nd with 1 spine and 19-21 soft rays; anal fin with 2 detached spines followed by 1 spine and 17-21 soft rays; pectoral fins short, comprised 1.5-1.8 times in head length; scales small, those on breast oval to strongly lanceolate, and partially embedded in the skin; lateral line very irregular and wavy, describing a convex curve over, and a concave curve behind pectoral fins; no lateral-line scutes (Ref. 57392). Brown above, silvery white below lateral line; lobes of dorsal and anal fins black distally; juveniles (to at least 12 cm fork length) with brownish black bars on sides (Ref. 3197, 57392).
