Upper eye just visible from the blind sight, lower eye generally slightly smaller, placed somewhat more posteriorly than the upper eye. Eye 5.2-8.4, equal to one half of interorbital space, 3-4 in postorbital part of head. Maxillaries large, 1.1-1.4 in head, reaching much farther than eyes. Posterior and anterior nostrils close together, those of the upperside in front of interorbital space. Teeth in the jaws long distant canines, sharply pointed, some of them curved, hastated or sagittated, in two or three rows, the hindermost smaller and more crowded. Those of the inner row are flexible, the outer ones fixed. A patch of small teeth on vomer and in a single row on palatines. Glossohyal, basihyals and gillarches with curved teeth, replacing the gillrakers. Origin of dorsal in or somewhat behind vertical through hindborder of lower eye. End of dorsal slightly before that of anal, which begins below about the 19th dorsal ray. Pectorals somewhat shorter than or equal to postorbital part of head. Ventral of blind side inserted somewhat behind the other one, their length about 2/3 of that of pectorals. Caudal scalloped, the outer and middle rays being longer than the others. Head scaly to between the eyes, where the scales get rudimentary. On this side the maxillary is scaly too. Scales with fine granulated striae, diverging to the hindborder, which is undulated.
