(A'. Iiciiiioinis I'all.) and oi' its variety, llic kiaui^- [PJ . ]temlonus 

 Pall. var. kiany, Moorkrol't) ; but the Prjevalsky horse has a 

 relatively larj^er head than tiie wild ass. The proportion of the 

 len<,4h of the head to that of the body is as 1 :2.21. In the onager 

 the proportion is as 1:2.29; and in the kiang as 1:2.25. As 

 regards the shape of the iiead, the Prjevalsky horse closely re- 

 sembles the onager and the kiang : a fact already referred to by 

 Poliakof, who added, however, that the head " is not so high 

 and is more slender at the end of the muzzle and in the region of 

 the bones of the nose." I can confirm the statement that the 

 head of the Prjevalsky horse is very like that of the onager and 

 the kiang; but I can obtain no proof that the end of the muzzle 

 and the region of the nasal bones are more slender tlian in the 

 Asiatic ass. The craniometrical observations which I made 

 revealed no difference.
