Meristic and morphometric data based on all lots examined since no statistical differences were found among populations studied from different localities. Body comparatively large (SL = 84-180 mm SL) and anteriorly deep. Dorsal body profile concave at nape, rising sharply in supraoccipital region, strongly convex from this point to dorsal-fin origin, nearly straight along dorsal-fin base, and very slightly convex from dorsal-fin termination to caudal peduncle. Ventral body profile continuously convex from tip of lower jaw to anal-fin origin, straight or nearly so and dorsally inclined along anal-fin base, slightly concave from anal-fin termination to origin of procurrent caudal-fin rays. Snout conical, shorter than orbital diameter. Lower jaw included in upper jaw when mouth is entirely closed. Maxilla extending slightly beyond vertical crossing posterior border of orbit.
