Second and third band from base of soft dorsal over occiput, fourth to sixth from base of caudal, the fourth along upper border of eyes, the fifth through eyes and the sixth, which is double on snout, through base of pectorals and below eyes.

In the lower jaw a few rows of small teeth with two irregular outer rows of enlarged ones. Preoperculum rectangular, serrate behind. Dorsal notched between spinous and soft part. Dorsal spines strongly, heteracanth, the first half length of second, which is somewhat shorter than the third one. Third spine longest, equal to post orbital part of head. Spines gradually decreasing in length to tenth, which is sub equal to the two following spines. Anterior soft rays as long as last spine, following rays gradually increasing in length, the longest about as long as sixth spine. Posterior rays rapidly decreasing in length, the fin rounded behind. First anal spine one fourth of second, which is somewhat stronger, but scarcely longer than third and equal to post orbital part of head. Soft anal gently rounded, as deep as soft dorsal.
