APODEMUS

ail area of iiitergradatiou between true nyJraticus ami the larger 

 Mediterranean form. Specimens from this region are indeter- 

 minate in characters, though for the most part apparently 

 nearest to the southern race. In addition to the race already 

 alluded to as inhabiting Crete several other insular forms have 

 become to a greater or less degree differentiated. That from 

 the island of Corfu ajjpears to be slightly more grey than that 

 occurring on the mainland of Greece. Specimens from the 

 Channel Islands and Scilly Islands show a tendency to be larger 

 than on the neighbouring mainland. But none of these local 

 races is sufficiently distinct to admit of characterization. On 

 the other hand, the Hebrides, St. Kilda, and Fair Isle, oft' the 

 coast of Scotland, are each inhabited by a peciiliar, well- 

 difierentiated form, sufficiently distinct to take rank as a species. 

 The few specimens that I have seen from the Shetland and 

 Orkney Islands appear to be indistinguishable from true 

 sylvaficus. It seems probable, therefore, that they have been 

 recently introduced.
