P3 is robust, and, as in the type, has a great transverse diameter with the protoconid placed well anteriorly. Internally there is a smoothly rounded cingulum, which continues from the antero-internal angle of the tooth, as in Gulo luscus, and is somewhat more developed than in the type. The crown of the tooth is much abraded showing that the animal was fully adult. Back of p7 is a space of 11 mm. for P4. MT is unfortunately broken anteriorly so that the blade cannot be described. The metaconid is preserved and is rather small and placed high up on the crown. The heel is of moderately large size with the hypoconid well developed, forming the external edge of the heel, while the entoconid is probably Back of mT there is a small alveolus, indicating a single-rooted tooth, which was even smaller than that tooth in the type. The contour of the lower jaw and especially the denti- tion are on the whole rather more suggestive of Gulo luscus than Meles taxus. !6The abraded condition of the tooth does not admit of a positive statement as to the presence or absence of an entoconid.
