Original description of Woodward, 1889 [2593]
Type. Detached tooth (PI. XI. fig. 5); British Museum. The provisional name of H. levis may bo given to the teeth from Stones field mentioned below. 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.
Form. & Loc. Hathonian (Stoncsfield Slate): Oxfordshire.
