Mouth shghtly oblique, jaws equal anteriorly. Posterior tip of the maxilla reach- ing a vertical slightly anterior to the orbital margin. Upper jaw 25-0-29-2 (M = 27-5) per cent of head, lower jaw 35-7-41-5 (M = 39-0) per cent, 1-7-2-5 (modal range 2'3-2'5) times longer than broad. Gill rakers. The lower i or 2 rakers (rarely the first 4) are reduced, the others are long and relatively slender. Occasionally some of the uppermost rakers are flattened, or flattened and bifid. There are io(rare)-i3, mode 11, rakers on the lower part of the first gill arch. No pseudorakers are present. Scales. Ctenoid ; lateral line with 33 () or 34 () scales, cheek with 2 or 3 rows. Five (rarely) to 7 (mode 6) scales between the upper lateral line and the dorsal fin origin, 5-7 (mode 6) between the pectoral and pelvic fin bases. Fins. Dorsal with 14 (), 15 () or 16 () spinous and 8 (), 9 () or 10 () branched rays. Anal with 3 spines and 7 (), 8 () or 9 () branched rays. Caudal slightly emarginate, scaled on its basal half or slightly more. Pectoral fin 22-0
