Head and opercular bones ornamented with tubercles; cheek and gular region covered with small, imbricating cycloidal scales; teeth more or less rugose and mammillated, those of the vomer in five, and those of the splenial in four regular series. Neural and haemal arches of axial skeleton of trunk not expanding sufficiently to encircle the notochord. Fin-rays robust, closely arranged, articu- lated, and divided distally. Pelvic fins present; dorsal and anal fins low and fringe-like, except in front where they rise to an elevated point, these two fins arising at about the same point and not extending in advance of the hinder half.
