Dorsal beginning before gill openings, its height much less than half height of body. Maxillary teeth conical, in two series, much smaller than the vomerine teeth. On the intermaxillary plate obtusely conical, when young in an outer series enclosing a mesial series of 3 large teeth, in old specimens more molar-like and in an irregular group, on the vomer stout and granular, in young specimens in 2 series, increasing later on in number and forming a pear-shaped group reaching much farther than the maxillary teeth and composed posteriorly of about 5 series. Mandibulary teeth in 2 series, increasing in old specimens posteriorly into 3 series, the outer series conspicuously smaller. Anterior nostril tubular on each side of tip of snout; posterior nostril above anterior fourth of eye with raised rim.
