The Bank- Vole, or as it may be better luuncd, the 

 Red Field-Vole, was first noticed by Pallas [Nov. Spec. 

 Glires, y). 247) as a variety of his 31us rutilus, and was 

 first separated as a distinct species in Schreber's great 

 work on the Mammalia. It has since received various 

 other names, owing to its variability in colour and pro- 

 portions. It may be readily distinguished Irom the other 

 smaller luiropean Voles by the red colour of its back,
