“ The canine is peculiar and differs markedly from that of the Raccoon. It is rather robust, very much recurved and grooved by a deep vertical sulcus upon its antero-internal face. This sulcus is but faintly indicated in the Raccoon. The postero-external face of the crown is marked by a sharp ridge which becomes more prominent near [Pg 230] the apex. The first premolar is not preserved, but its alveolus indicates that it was a single-rooted tooth, placed behind the canine after the intervention of a very short diastema. ”

“ The heel is not very prominent, but the basal cingulum is well developed, both in front and behind. As compared with the Raccoon, the second premolar is more complex in that it has two cusps instead of one. In the third premolar the posterior cusp is much better developed, and placed more obliquely than in the corresponding tooth of Procyon; the heel is moreover not so broad. ”

“ Cercoleptes, moreover, has a moderately deep groove upon the antero-internal face of the canine, but differs from that of Leptarctus in having an external groove as well. Cercoleptes again resembles Leptarctus in having only three premolars in the lower jaw; the middle one, however, has only a single cusp upon the crown, whereas Leptarctus has two.
As compared with Bassaricyon, [2] the jaw is more robust, shorter and deeper, with a more prominent chin. The two genera differ again in the number of premolars. ”
