Notes on Apodemus. 



Hinton remarks, on p. 119 of (4), that "in practically every 

 island of the Hebrides, difierentiation from the parent stock has 

 proceeded so far that the most logical course would be to describe 

 the mice of each island as a distinct subspecies." In his paper, 

 however, lack of abundant material compelled him temporarily 

 to group the mice of Ghia and Tiree with those of Grreat Cumbrae 

 as ^. h. Gumbrce, and the mice of Jura and Islay with those of 

 Mull as J.. A. inaclean. The distinguishing characters he observed 

 in them are well confirmed by the extended series now available, 

 and others are made apparent; there is left no doubt of the 

 distinct nature of each, which is accordingly here separated.

Description. In general dorsal colour this form nearly resembles 

 A. h. cumbrcB ; the flanks are slightly less bright than those of 

 A. h. ciwibrce, and are little lighter than the back. The con- 

 trast between flanks and belly is not striking ; the latter is 

 silvery, with slight trace of the pectoral spot.
