THE HEBRIDEAN FIELD MOUSE 
The figure in the Plate was drawn from one of the specimens obtained 
by Dr. Eagle Clarke. 
THE HEBRIDEAN FIELD MOUSE. 
Mus sylvaticus hebridensis, W. E. De Winton. 
This variety is larger and more stoutly built than the Common Wood 
Mouse and has also longer feet and shorter ears. 
In colour there is less distinction between the upper and under parts, 
the latter being duller and strongly suffused with buff, with a patch of this 
colour on the chest. It appears to be confined to Lewis and Barra, Outer 
Hebrides, and was first discovered by Mr. J. Steele Elliot and described later 
by Mr. W. E. De Winton. 
THE IRISH WOOD MOUSE. 
Mus sylvaticus celticus, Barrett-Hamilton. 
This is a small race about the size of Mus sylvaticus, with dark upper 
parts and white on the under side, inhabiting the South and West of Ireland 
and also the Hebrides and Skye.
