1 have already commented on the resembla,nce of the Shan-si 

 Field-Mouse to that of Korea, and now find that those from Kan- 

 su are again similar in every respect and should undoubtedly be 

 referred to the same subspecies, the animal therefore presenting 

 a noteworthy example of the uniformity of the Fauna of China 

 N. of lat. 34°. As usual, the representative southern form in 

 Sze-chwan is at once distinguishable by its much darker colour.
