NO. 8 NEW AFRICAN UNGULATES HELLER 



matic breadth, 128; nasals, 230; breadth of horn pedicle, 89; length 

 of horn pedicle from orbit to bifurcation, 11 1 ; length of upper tooth 

 row, 97; distance from first premolar to premaxillse tip, 36.5. 



The Smithsonian African collection contains three specimens of 

 this race shot near Lake Nakuru by Kermit Roosevelt. These are 

 distinctly different from the two mounted heads of neumanni from 

 Lake Rudolf in the Tring and British Museums. 



The horns of the Lake Rudolf specimen are much wider, practi- 

 cally the shape of those of tora, of which neumanni appears to be a 

 race. The Nakuru specimens, on the other hand, have less widely 

 spread horns, more or less intermediate between those of cokci and 

 jacksoni in shape, and on this account they have usually been con- 

 sidered hybrids between these species by sportsmen. This, however, 

 is not the case, although they occupy a somewhat intermediate 

 geographical position. They are found on the northwestern edge of 

 the range of cokei, and are really surrounded by this species and 

 actually removed by many miles from the nearest jacksoni. The 

 Nakuru race is known only by a single herd which inhabits the 

 country lying between Lakes Nakuru and Elementaita. From 

 neumanni, which occupies the region bordering the northeastern 

 shores of Lake Rudolf, they are separated by several hundred miles.
