 found in the British Isles. The male is somewhat over two feet 

 in height at the withers, of a dark reddish-brown colour in summer,

 for some distance, then bifurcating, and the posterior branch again 

 dividing. The Roe dates from the Pleistocene period. Extinct 

 Deer from the Continental Pliocene have been provisionally referred 

 to Capreolus.
