MAMMALIA. 51 



a. Horns lyrate, (or rarely cylindrical subspiral,) strongly ringed 

 at the base. Nose ovine, without any naked muffle; inguinal 

 pores deep. Crumen generally distinct. 



a. Nose high, compressed; nose-hole of skull very large. 



1. SAIGA. 



Horns short, strong, lyrate, annulated, white. Nose compressed, 

 very high, rounded. Nostrils very close together. Crumen di- 

 stinct. Fur soft. Skull : nose-opening very large, extended back 

 to over the eyes, t. 6. f. 1. 2. Pallas, Spic. Zool. xii. t. 3. f. 9, 10.

 Colus, " Wagner." 



Mr. Turner observes, "This genus (Gazella) seems prone to 

 exhibit in certain species inhabiting more temperate regions, en- 

 largements of, or appendages to, the respiratory passages ; for 

 example, the enlarged larynx of G. gutturosa, the elevated nose 

 of G. Coins, and the appendages to its sides in the Chiru (G. 

 Kemas) ; these seem to be physiological adaptations, in no case 

 marking a group, and therefore insufficient to warrant generic 

 distinction, which has been made in the two latter instances. 

 However, not having as yet seen entire skulls of these species, I 

 retain them provisionally in this genus, judging by the horns. I 

 think few naturalists will set forth, with Mr. Gray, the colour of 

 the horns of the Saiga as a generic character." If Mr. Turner 

 had consulted Pallas' s description and figure of the skull of the 

 Saiga, or Hodgson's figure of the skull of the Chiru, I think he 

 would have been satisfied they were good genera.
