This species is a native of Siberia, and forms 

 its nest beneath turfy ground, with several minute 

 entrances. It is supposed to feed chiefly on the 

 roots of the Lilium pompoiiium, and Allium tenuis- 

 simum, which it collects for its winter provision. 

 The male and female, together with the young of 

 one year's age, reside in the same retreat. This 

 species is not observed to migrate. It varies in 

 size, and the males are in general much smaller 

 than the females. The usual length seems to be 

 about four inches, and the tail about an inch and 

 half ; but some of the males do not exceed three 

 inches from nose to tail.
