Color: Variable; preserved specimens brownish to dark brown, caudal peduncle and caudal fin pale yellowish. Scales of body with dark center and pale hind margin. A broad dark area on upper part of snout through eye to upper edge of operculum, cheek lighter. A pale yellowish band along upper lip and another along lower lip, an irregular broad greenish band below lower lip and pale yellowish band on chin. Two or three pale yellowish streaks behind eye. Dorsal pale yellowish with an outer broad violet band, the lower edge of this band slightly darker; a violet basal band posteriorly on soft fin. Anal yellowish with greenish tinge, 1/4 to 1/3 of basal part violet. Pectoral pale brownish, a pale streak along upper one or two rays, distal edge of the fin hyaline. Ventral pale.

Head equal to depth of body, 2.6-2.7 in standard length, 3.1-3.2 in total length. Eye diameter 6.5-7.7 in head, 2.4-3.0 in snout and 2.1-2.5 in convex interorbital space. Lips narrow, leaving greater part of dental plate uncovered. Inner upper lip poorly developed, its connection with the outer lip somewhat nearer to corner of mouth than to symphysis of upper jaw. Teeth greenish, lips narrow, covering much less than half of dental plates, a rudimentary canine posteriorly in large specimens, absent in small specimens. Nostrils small, the posterior less than an eye diameter before eye. Two rows of scales on cheek, preopercular flange broadly naked. 4 predorsal scales. Dorsal fin spines and rays subequal, equal to twice eye diameter or longer. Pectoral fin longer than head without snout. Anal similar to dorsal. Caudal fin truncate or slightly rounded.
Number of spines and rays in the dorsal fin: IX, 10; number of spines and rays in the anal fin: III, 9; number of rays in the pectoral fin: ii, 13; number of spines and rays in the ventral fin: I, 5; number of scale rows along the lateral line: 24-25; number of horizontal scale rows usually counted from origin of the dorsal fin to the lateral line and from anal origin to the lateral line: 2+1+6½.
