with sides ; underparts and inner surface of legs dull white to 

 base of hairs, or with a slaty under-tint, the line of demarcation 

 along sides sharply defined ; feet, a light, indefinite yellowish 

 brown ; tail obscurely bicolor, the hairs everywhere ochraceous- 

 buff, the skin light brown below, dark above. Summer pelage 

 (Germany) : upper jjarts noticeably darker and duller than in 

 winter, approaching the russet of Ridgway, but with a tinge of 

 rufous ; sides dull cinnamon ; underparts dull ochraceous-buff, 

 the line of demarcation along sides inconspicuous, the median 

 line, especially of chin and throat, often with traces of white in 

 the form of ill-detined lines and blotches ; feet and tail as in 

 winter, but more thinly haired and therefore more obscurely 

 coloured.

Remarks. — For the present it seems necessary to regard all 

 the harvest mice of western Europe, including England and 

 northern Italy, as belonging to a single race. The differences 

 which have been observed to exist, notably between British and 

 German specimens, prove to be merely seasonal.
