In percentages of standard length : body depth 30-5-36-5, head length 24-3-27-5 ; snout length 5*0-6-7, eye diameter 5*i-7*9 (negative allometry with ), length of upper jaw 12-2-14-7, length of lower jaw 13-2-15-9 ; pectoral fin length 17-4-21-1 (slight negative allometry with ), pelvic fin length 7-4-9-7, length of anal fin base 27-3-32-5 ; pre-dorsal distance 45,3-5i,5, pre-pelvic distance 43'3~47*5, pre- anal distance 63-4-71-5. Body fairly strongly compressed, its width 2-25-3-50 times in its depth, the latter greater than head length (depth independent of size of fish in the range examined) ; belly strongly keeled, the scutes more prominent behind the pelvic fins. Eye dia- meter greater than snout length except in fishes over about 300 mm ; eye entirely covered by adipose tissue. Maxilla reaching to between verticals from anterior pupil border and eye centre, and a little beyond articulation of lower jaw ; pre-maxillae with a single row of small conical teeth (about 20 on each side) separated by a median edentulous ' notch'; hypo-maxillae present, bearing fine denticulations ; maxillae with similar denticulations along lower edges ; two supra-maxillae present, the 2nd (posterior) almost triangular, with the lower part of the expanded portion much deeper than the upper, the 1st (anterior) about three-quarters eye diameter and four times as long as deep. Lower jaw twice as long as deep, projecting strongly beyond up
