In size, they arc as small as the teeth of H. polyprion, but seem to be spe-cifically distinguished by the following characters: Crown of principal teeth high, compressed, with a largo erect median cone and two or three lateral cones, narrow and acutely pointed; coronal surface of all the teeth smooth, except (juite at the base, where vertically wrinkled. Hoot depressed, flattened, expanded posteriorly.
