Mule- Deer 269 



location with that of Mazama Columbiana, is sooty at base, and white apically. 

 The tail is coloured much as in M. Columbiana, but has a longer terminal 

 switch ; upper side and extremity of tail all black, lower side white 

 mesially, and naked towards the base. The pelage of this deer is short 

 and coarse in comparison with that of the white-tailed or Virginian deer, 

 or the black-tailed deer of the Columbia River region ; and, as would 

 naturally be expected, is not so red as that of the latter. The skull has 

 very nearly the same conformation as that of M. Columbiana, the lachrymal 

 pit being deeper than in the Virginian deer, but shallower than in the 

 mule-deer. The same intermediate condition obtains with respect to the 

 vomer, in the relationships of the nasal and premaxillary bones, in the form 

 and size of the teeth ; and, in short, the whole animal appears to be a 

 compromise between the characteristics of the white-tailed and mule-deer. 

 Is it possible that it may be a half-breed between the two ?
