Red Mouse 



Peromyscus nuttalli (Harlan) 



Length. 7.40 inches. 



Description. Differs from all the other long-tailed mice in its 

 bright fulvous colour above and strong fulvous suffusion 

 below and the absence of a sharp line of separation between 

 the colours of the upper and lower surface. No dusky 

 patch at the base of the whiskers, and young fulvous, 

 like the adults, not gray, as in the white-footed mice. Ears 

 rather short.

Although related to the white-footed mice, the red mouse is 

 very distinct in many respects, especially in its shorter ears and dif- 

 ferent colouration. It is not a common species.
