Text Appearing After Image: 13 Figs. 11 to 13. Dipoides, near tortus (Leidy). Cedar Mountain beds, Stewart Valley, Nevada. Fig. 11. Mandible with P4, no. 19802, X 2; tig. 12, P4, no. 19804, X 2; fig. 13, P4, no. 19803, X 2. MYLAGAULTJS ?, sp. A fragment of a large molar (no. 19801) from Stewart Valley (locality 2027) represents a mylaganlid form, but the tooth is too imperfect for specific determination. The specimen does not appear to differ distinctly from the fourth premolar of Mylagaulus, and may be referred provisionally to that genus. APLODONTIA ?, n. sp. A single upper premolar, no. 19798 (fig. 14), from Stewart Valley, (locality 2027) represents a rodent evidently belonging in the group of the Aplodontidae, but not corresponding exactly to any form known to the writer. It shows resemblance both to Meniscomys and to Aplodontia, but does not duplicate the characters of either. The crown of the tooth is worn down close to the large, very slightly divergent roots upon which it is supported. On the occlusal face there are at least four enamel lakes, which extend down almost to the lower end of the crown. The form of the crown, taken with the depth and the tendency to cylindrical form of the enamel lakes, suggests that the normal unworn crown was short hypsodont.
