114 CATALOGUE OF UNGULATES 



Typical locality Bad Lands between White and Cheyenne 

 Rivers, South Dakota. 



Described from the evidence of skulls and horns; the 

 former of which are characterised, in addition to certain 

 structural peculiarities, by their large size and the great 

 proportionate length of the row of cheek-teeth, while the 

 latter are stated to be longer and more slender than in the 

 typical race.

 grey according to Hornaday. Rump-patch small, com- 

 pletely divided by dark median line, and frequently indistinct ; 

 under-parts and limbs (except where white) much darker 

 than back, contrasting sharply with white areas. Tail 

 short and sparsely haired. Forehead less concave than
