Greatest body depth at dorsal-fin origin. Dorsal profile of head distinctly convex from margin of upper lip to region approximately at vertical through anterior nostril, nearly straight from that point to posterior tip of supraoccipital spine. Dorsal profile of body slightly convex from tip of supraoccipital spine to dorsal-fin origin, posteroventrally-inclined along dorsal-fin base, nearly straight from posterior terminus of dorsal-fin base to adipose fin, and slightly convex from posterior part of adipose-fin base to origin of dorsalmost procurrent caudal-fin ray. Ventral profile of head and body distinctly convex on anterior tip of dentary, gently convex from this point to anal-fin origin, straight and posterodorsally inclined along anal-fin base.

. Examined specimens lack guanine on body or head. Ground color tan. Dark chromatophores concentrated on middorsal surface of head and body. Anterior portion of both dentary and maxilla with dense concentrations of dark chromatophores. Ventral portion of head with scattered, dark chromatophores. Humeral region with two dark blotches, anterior blotch more evident and bordered anteriorly and posteriorly by regions of paler coloration. Anterior blotch vertically elongate, wider dorsally, and situated immediately posterior to opercle. Posterior humeral blotch much less conspicuous, somewhat square-shaped, and formed by dark chromatophores concentrated over three or four scales immediately dorsal to anterior portion of midlateral stripe. Midlateral dark stripe extending from pale area posterior to humeral spot to end of caudal peduncle, more conspicuous and relatively wider posterior to vertical through dorsal-fin origin. Stripe on four middle caudal-fin rays extending to tips of rays. All rays with thin line of chromatophores along margins, giving dark contour to each ray. Adipose fin with scattered dark chromatophores. Smaller specimens with overall lighter ground body and fins coloration and with posterior humeral blotch less distinct than in larger individuals.
