Diagnosis
Reference | Diagnosis | |
---|---|---|
F. W. True 1894 | Ascending ramus of mandible short and erect. Condyle terminal. Coronoid process well developed, uncinate, and near the condyle. Size very small, tail short. Plantar tubercles, six. Soles hairy. With Vesperimus and Onychomys, this subgenus will form one section of the genus Sitomys. it is closerly allied to the former than to the latter. In Vesperimus, the nearest ally is S. (Vesperimus) michiganensis, which has many of the characteristics of S. taylori, but so far as regards the skull is typical of the subgenus to which it belongs. |
