forks being nearly equal. There is sometimes a smaU snag on the 

 inner side of the lower part of the beam ; but this is ofteu wanting. 

 The outside of the metatarsus has a large elongated gland. Hoofs 

 triangular, narrow. The skull broad ; suborbital pit large, tri- 

 angular. The skulls of both sexes are described in my ' Catalogue 

 of Ungulate Mammalia in the British Museum,' p. 283. There are 

 two weU-described species found in the Western States of North 

 America. 



The Long-eared or Mule Deer of the Western States of North 

 America are very imperfectly known in Europe ; and the examina- 

 tion of the horns, which I had not before seen, has shown me that 

 they have been very erroneously placed with the genus Cariacus. 

 Dr. Speucer Baird, in his excellent work on the Mammals of North 

 America, has formed for them a distinct section of his genus Cervus. 



The Cariaci or Savanna Deer have the upper part of the beam of 

 the horns curved forward, with the upper branches arising from its 

 hinder edge ; they generally have a single subbasal snag some dis- 

 tance from the base ; and the outside of the metatarsus has a short 

 broad gland. The skull is elongate, narrow, and the suborbital pit is 

 small. The Mule Deer, on the contrary, have a doubly forked sub- 

 erect horn, like the genera Blmtocerm and Furcifer of South and 

 Tropical America. They differ from both these genera in having a 

 large elongated gland on the outside of the metatarsus, rather dif- 

 ferently formed horns, and a broad short skuU.
