THE BANK VOLE 



Sheppard in June 19 12. In colour the upper parts of this variety are a 

 deep reddish brown, the under parts yellowish. 



Another large form [Evotomys erica ^ Barrett-Hamilton and Hinton), 

 closely related to the one inhabiting Mull, has been found among heather 

 on the Island of Raasay, which lies between Skye and the mainland. 

 Describing this vole. Major Barrett- Hamilton says {A History of "British 

 Mammals^ p. 425): "Unlike E. alstoni^ but in this respect resembling 

 skomerensis and ccesarius^ it has undergone considerable specialisation, 

 apparently to fit it for subsistence upon a coarser and probably more 

 exclusively vegetarian diet." The colour of the upper parts is dark brown, 

 the under parts are strongly tinted with buff.
