184/.] On Various Genera of the Ruminants. 709 



Ribs 14 or 15 pairs. 



A true dorsal ridge, confined to the withers. 



Mufle small. 



Dewlap none. 



Types. Americanus et Poephagus. 



The latter is the Yak or Chouri Gau. 



It inhabits all the loftiest plateaux of High Asia between the Altai 

 and the Himalaya, the Belut Tag and the Peling mountains, and is 

 found wild as well as tame. It cannot live on this side the Himalayas 

 beyond the immediate vicinity of the snows, where the tribes of the 

 Cachar or Juxta-nivean region of the sub -Himalayas rear large herds 

 and cross-breed with the common Ox. The Yak ruts in winter and 

 produces young in autumn, after the usual period of Bovine gestation. 

 Small intestines 107 feet. Large 33\ feet. Ccecum 2\ feet. Width of 

 small gut 1^ inches ; of great, 2 inches ; of ccecum 4 inches. Ccecum 

 simple, that is, not sacced nor banded. 



5. Genus Btjbaltjs. 



Bhainsa. Arna. 



Cranium large, elongate, compressed, exhibiting great excess in the 

 facial over the frontal and cerebral portions. 



Frontals short, narrow, convex, forming an obtuse angle with the 

 occipital plane. 



Occipital plane larger than the frontal, spheroidal, moderately in- 

 dented. 



Condyles of the foramen and lower jaw low, and the jaw little curved. 



Horns attached to highest line of frontals, depressed, angular, and 



horizontal. 



Thirteen pairs of ribs. 

 No true dorsal ridge nor hump. 

 Mufle very large and square. 

 Dewlap medial. 



Types. Bubalus Buffelus, or the Bhainsa, and Bubalus Arna or the 

 Arna.* 



Habitat of the tame, universal ; of the wild, also every where where 

 adequate cover and swamp exist. The haunts of the Arna or wild 



* Bornouensis and Brachycerus are to my mind no Buffaloes, and their united horns 

 form a character at variance not only with the genus but the family. Hence I denomi- 

 nate them from this feature Syncerus (aw et Kepos). They are foreign to India, the laud 

 of the true Buffaloes.
