(BMNH 1896.9.11.6) on lower first gill arch with seven short rakers, followed by a series of 12 long rakers. The lower four of those intercept by narrow plate shaped rakers. These are smaller than in most species and placed toward the inner margin. Upper gill raker with a serie of three semi long rakers and three plate like rakers intercepted, followed by two very short rakers.
