i86 THE HORSE AND ITS RELATIVES 



fossil remains of the genus Equus, it is generally- 

 considered that during the Pleistocene period either 

 the kulan or the onager (for it is impossible to 

 distinguish between them in the fossil state) ranged 

 into Central and Western Europe. Dr. Nehring,^ 

 indeed, believed that all the remains of small equines 

 from France and Germany were referable to these 

 animals ; but Prof. M. Boule,^ while admitting the 

 occurrence of the onager in Western Europe, refers, 

 as will be more fully noticed in the sequel, the 

 majority of such remains to the ass.
