Description
Size: 35-143 mm

Color: In preserved specimens grey, reddish olive or blue above, margaritaceous below. Head lighter or darker violet 5 generally lighter violet or blue broad bands, bordered by a narrow dark violet line. The two anterior ones from anterior border of eye more or less club-shaped, widening anteriorly. The first to middle of upper jaw, the second to corner of mouth. From the posterior three bands the uppermost is short, beginning in the scaly patch on operculum a short way along hind border of operculum. The two following run more or less parallel to each other backwards from behind eye to middle and lower end of opercular hind border, where they are generally somewhat curved backwards. Seven dark violet transverse bands on back, tapering inferiorly. The first, often connected on back with the second and often broken into blotches interiorly, to superior part of axil of pectorals, which generally has also a dark band along its base. The second from origin of dorsal, descending to sides at some distance behind axil of pectoral. The third, fourth, fifth, and sixth from base of dorsal to sides, decreasing in size posteriorly. The seventh forms a short on caudal peduncle. A light reddish longitudinal from middle of sides to middle of base of caudal. A second less distinct one parallel to it, from base of pectoral to lower caudal rays. Dorsal light reddish, with a longitudinal dark violet band, less distinct in young and here often only distinct between the three anterior spines and the last spine and anterior soft rays. Anal light yellowish, generally with a back blotch between the anterior soft rays. Pectorals dusky at tip. Ventrals light yellowish, the rays often darker.

Height 3-3.1, 3.6-3.7 in length with caudal. Head 3, 3.5 in length with caudal. Height of head 1.3 in its length. Eye 5.4-6.7, 1.6-2 in snout and 1.2-1.3 in somewhat convex inter orbital space. Mouth horizontal, protractile, its corner scarcely or not reaching to below anterior nostril. Teeth in single crowded series in both jaws, pointed, somewhat curved, the two anterior ones in the upper jaw moderate canines, the four anterior ones in the lower jaw also longer than the others. Head naked, with exception of a rounded patch of scales on upper part of operculum, consisting of 3 transverse rows, each of 1-3 scales. About 8 scales before dorsal. Dorsal spines short and slender, the first less than eye, the last about equal to eye. The membranes between the spines scarcely incised. Soft dorsal slightly rounded, much higher than spinous part, the first ray equal to snout, the last ray shorter. Origin of anal below last dorsal spine. Anal spines slender, second one longer than first and about equal to one and a half diameter of eye or somewhat longer, Soft anal similar to soft dorsal. Vertical fins with a low scaly sheath. Pectorals with the hind border slightly emarginate, half length of snout shorter than head or somewhat shorter. Ventrals somewhat pointed, scarcely less than post orbital part of head. Caudal truncate or slightly rounded in young ones, in older ones the outer rays are produced and the fin is semi-lunar, with pointed lobes.
