 several hundred miles." 



That this hartebeest (of which the type is in the U.S. 

 National Museum) is not entitled to rank as a species, may 

 be considered certain, as the under-mentioned specimens 

 show an almost complete gradation to typical skulls of cokei.

 intermediate in character between those of typical nakurcc 

 and those of the next specimens.

 which is more buffish and less rufous on the body, while the 

 rufous of the forehead of the latter is replaced by tawny.

 shorter and wider horn-pedicles (width of latter 94 cm., 

 length 114 cm.). 



This is a highland race, whereas the typical form is a 

 lowland animal.
