tributed over Europe and Western Asia, being one of the species 
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, 
with a white patch on the rump. The small antlers are approxi- 
mated at their bases, and consist of a rugged beam rising vertically 
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.

small and but slightly prominent. Auditory bulla much inflated. 
Angle of mandible much produced backwardly (Fig. 134); alveolar 
margins of mandible in diastema sharp and everted. Canines of 
male very large, and slightly convergent. Vertebre: C 7,D 12,

on metatarsals. Foot 
glands small in fore feet, 
deep in hind ones.

has the hemispheres much
