One of the three races into which L. timidus, L., has been 



separated. 

 Lepus hibernicus, Bell ; Irish Hare. This form, now ranked as 



a species, has been introduced into Carnarvonshire and the 



Island of Mull. 

 Muscardinus avellanarius, Linn. ; Dormouse. No subspecies. 



Does not occur in Scotland. 

 Evotomys glareolus britannicus, Miller; British Bank Vole. 



Nine subspecies of E. glareolus, Schr., are described in the 



Catalogue. 

 Evotomys skomerensis, Barr.-Ham. ; Skomer Vole. Only known 



from Skomer Island, off the coast of Wales. 



Of the seven subspecies of Microtus agrestis, Linn. (Field 

 Vole), differentiated in the Catalogue, we have the three 

 following : 



Microtus agrestis exsul, Miller. North and South Uist, Outer 



Hebrides. 

 Microtus agrestis hirtus, Bellamy. Distribution given as 



" England and the lowlands of Southern Scotland." Among 



the localities given are Hawick and Crieff.

 Microtus sandayensis westr^e, Miller. Known only from the 



island of Westray, Orkney. 



The species Arvicola amphibius, L., is divided into the two 

 following subspecies, both confined to Britain. A. terrestris, L., 

 from Sweden is very closely related.

 " England and Southern Scotland : exact northern limits of 

 range not known." 



Arvicola amphibius reta, Miller; Black , Water - Vole. 

 " Scotland except southern portion ; " but limits of distribution 

 require investigation. The name reta ( = ater reversed) has 

 been substituted for ater, MacGillivray, which is precluded, it 

 appears, by the rules of nomenclature. 



Under the specific name Apodemus sylvaticus, L., are embraced
