WILD CREATURES OF GARDEN AND HEDGEROW 



but there is a sub-species A. s. butei known only 

 from the Island of Bute. The Field Mouse of the 

 Hebrides is regarded as a distinct species from 

 Sylvaticus; it is the A. h. hebridensis of de Win ton, 

 and four sub-species of it have been recognised from 

 as many different islands. There is not space to 

 deal with them here. St. Kilda has its own Long- 

 tailed Mouse, called A. hirtensis. The peculiar Long- 

 tailed Mouse found on Fair Island is A.f.fridariensis, 

 and there is a sub-species of it found on Yell, and on 

 Mainland, Shetland. The Yellow -necked Mouse of 

 de Winton is nearly related to a similar large mouse 

 found in Denmark, etc., but is sufficiently distinct 

 to be dubbed A. flavicollis wintoni.)
