| A. S. Woodward 1918 | A robust species about 18 cm . in length . Length of head with opercular apparatus somewhat exceeding maximum depth of trunk , which is twice as great as depth of caudal pedicle and contained about five times in total length of fish . External head - bones coarsely tuberculated or rugose ; marginal teeth long and slender . Dorsal fin arising at the end of the anterior third of the back , half as long as the trunk , comprising not less than 25 rays , mostly bifurcated , of which the longest do not equal the depth of the trunk at their point of insertion ; pelvic fins arising slightly in advance of the middle point between the pectorals and the caudal . Scales smooth , with finely serrated hinder border except towards the hinder end of the caudal region where they are entirely smooth . | |
