Vomer with a transverse patch of similar teeth, those on palatines somewhat stronger. Longest spine of first dorsal equal to inter orbital space. Third or fourth ray of second dorsal longest, equal to distance between hind border of eye and base of suprascapular spine. Rays of second dorsal rapidly decreasing in length posteriorly, the last ray about on half diameter of eye. Origin of anal below origin of dorsal, end of anal below end of dorsal. Posterior anal rays slightly longer than the anterior ones and about equal to snout and eye. Pectorals equal to head without snout, ventrals equal to post orbital part of head. Pelvic spines behind vertical through antero-inferior edge of maxillary. Caudal slightly rounded. Upper edge of opercle descending backward. Both nasal valves long and tubular.
