TECHNICAL NAMES OF BRITISH MAMMALS. 103 
first-named, with the “Ruddy Vole” of Northern Europe, and 
the “‘ Red-backed Voles”’ of North America, may be distinguished 
by its semi-rooted teeth and more murine skull from the true 
Voles, of which our Water Vole and Short-tailed Vole are repre- 
sentative. The latter must of course be called Microtus, not 
Arvicola; while for the Bank Vole and its allies Dr. Coues’s 
term Hvotomys is available. 
Lastly, in the Hares we have a repetition of the ever-recurring 
Scandinavian muddle. Linnzus’s Lepus timidus was of course 
the northern, varying Hare, to which alone the name should be 
restricted ; the Common Hare should take Pallas’s name, Lepus 
europeus.
