B. IRELAND. 



Fragmentary jaws and teeth occur abundantly in the caves of 

 Cos. Clare, Cork, and Sligo, associated with the remains of Dicrostonyx. 

 It is a remarkable fact that, although remains of Lemmings are common 

 in the Irish Pleistocene, no trace of a YoXq living or fossil has been 

 found in Ireland. A very large collection of fragments and detached 

 teeth was lent to me some years ago by the Irish National Museum, 

 in order that I might search for a Vole; on going through the lot 

 with the utmost care I found nothing blit Dicrostonyx and Lemmus. 



C. CONTINENTAL EUROPE. 



Fossil remains of Lemmus have been found at many localities in 

 Germany, Austria, Hungary, Russia, France and Belgium, and have 

 been recorded by Hensel, Nehring, Woldrich and others. Nehring, 

 who refers these remains to L. obensis, has given a list of such occurrences 

 (" Ueber Tundren und Steppen," 1890, p. 147). I have seen lower 

 jaws from Thiede, Brunswick (British Museum), and Kleine Scheuer, 

 Wurttemberg (lent by Dr. Frank Corner), but have no other personal 

 knowledge of the Continental fossil form. 



Recently Lemmus lemmus has been recorded from the Pleistocene of
