This species was founded by Ameghino on a single lowerpremolar 3 which is 3 mm. in length. No further descrip-tion is given and no figure. Proborhyaena Ameghino Proborhyaena Amegh., 1897, Bol. Inst. Geog. Argen., t. 18, p. 501. The genus is founded on a large lower jaw carrying thecanine and premolars 3 and 4 and roots or alveoli for theother teeth. It is the largest carnivor recorded fromPatagonia, and as large as a small bear. It is not possible 2l8 THE DESEADO FORMATION OF PATAGONIA to place Its exact relationships, for the most essential teethare wanting, but it is certainly a distinct genus as indicatedby the reduced size of premolar 4 and the plump characterof the teeth.
