Eyes large, their bulge subequal in size to the spiracles, and to half, the intelspiracle width. Skin smooth; a series of flattened spines on the median line of the back extending backward almost to the level of the posterior insertion of the pectorals; these form an irregular double row before the shoulders, and there are one or two spines on each side of the median series on the shoulders themselves. Width of the mouth 1.4 in its distance from the end of the snout. Jaws undulous; teeth small and tessellate, with flattened points directed backwards; a series of larger pointed ones on each side of the upper jaw.
