MULE-DEER 
109 
The BLACK-TAILED DEER (Mazama [Dorcelaphus| columbiana). 
(Otherwise Carzacus columbianus, or Odocotleus columbianus.) 
Nearly allied to the mule-deer, but of inferior size, with relatively 
smaller ears and finer hair; but specially characterised by the shorter 
gland and tuft on the hind cannon-bone, and the larger and longer 
tail, of which the upper surface is black and the lower mostly white. 
Distribution.—Western North America, from Alaska, British Columbia, 
and Vancouver to California. 
The Alaskan race (JZ. c. sttkensis) 
has the upper surface of the base of the tail coloured like the 
back ; in the Californian JZ. c. scaphiotus the general colour is 
paler and the ears are larger.
