Specimens examined. — Twenty-two, from the following 

 localities : — Holland, Oosterbeek, 2 ; Graveland, 4 : France, 

 Dinan, Cotes-du-Nord, 4 ; Duclair, Seine-Inf^rieure, 2 ; 

 Seine-Inferieure, no exact locality, 3 ; Manonville, Meurthe- 

 et-lMoselle, 2; Meurtlie-et-Moselle, no exact locality, 5. 



Bemarhs. — While the exact limits of the ranp;e of this 

 squirrel are still unknown, it is probable that the animal 

 occupies the coast-reo-ion from Denmark southward at least 

 to Brittany. In the Landes of Soutii-western France it is 

 apparently replaced by the North-Spanish squirrel or a closely 

 related form. Westward it extends across France to the 

 Valley of the Moselle. 



In colour, as well as in range, Sciurus vulgaris russus and 

 S. V. rutilans correspond with tlie two races of red-backed 

 voles, Evolomys hercynicus rubidus and E. h. hercynicus, 

 occurring in the same regions.
