Head greyish. Dorsal fins and anal fin black with yellow margin, or totally yellow. Other fins yellow. Pectoral and ventral fin with blackish base.

Body oblong, anteriorly cylindrical, posteriorly compressed, height 3 3/4 - 4 in total length. Head obtuse, convex, depressed, 3 1/2 in length, 3 2/3-4 in total length. Dorsal profile convex. Eye 3 1/3-4 in head, interorbital 1-2 eye diameters. Snout depressed, convex, shorter than eye, tip before middle of eye. Mouth very oblique, lower jaw prominent. Maxillary extends to below anterior part of eye. Teeth in many rows, pointed, outer row in upper jaw enlarged, distal, conical. Laterally on head some longitudinal rows of mucous canals. Head scaled from a little behind the eye to insertion of first dorsal fin with very thin cycloid scales, which fall out readily, therefore the head behind the eyes is in preserved specimens mostly naked. Opercle and subopercle scaled for the greater part with ctenoid scales, on opercle in 4 rows. Scales of body ctenoid, laterally posteriorly the largest. Body scaled below first dorsal fin. Dorsal fins distant. First dorsal fin half as high as body, third and fourth rays are the longest. Second dorsal and anal fin a little higher than first, obtuse. Pectoral and caudal fin obtusely rounded, shorter than head without snout. Ventral fin obtuse, shorter than pectoral fin.
