The cranium and mandible, from the Pleistocene of the (Fig.) banks of the river Plata, Buenos Ayres. The cranium, of wbich the palate is represented in the accompanying woodcut (fig. 24), is imperfect posteriorly, and the man- dible has lost the hinder part of the right ramus. The teeth are in a well-worn condition. Prom the suppression of pm- 1, the double roots of pm. 3, the squareness of m. 1, and the smaller extent of the back- ward prolongation of the talon of m. 2, it is pretty certain that the South-American fossil is generically distinct from Ursus, and there is as little doubt that it is equally distinct from Hycenarctos. It forms, in fact, a genus almost pre- 1 Catalogue des Especes d'Animaux Fossiles recueilles dans UAinerique de Sud (Parana, 1860), teste P. Gervais. 2 Zool. et Pal.
