背的软条 (总数) : 116 - 123; 臀棘: 2; 臀鳍软条: 74 - 87; 脊椎骨: 125 - 129. Body very elongate and compressed. Head profile straight or scarcely convex, with sagittal crest strongly elevated. Both jaws have a short dermal process; the lower jaw longer than the upper jaw. The dorsal fin has a few weak anterior spines that hardly differ from the soft rays.
