occipital portion of the skull, and especially of the occipital condyles. 

 When placed by the side of a B. vnicornis of the same size and con- 

 dition of teeth it stands rather higher, and is immediately known by 

 the length and slenderness of the nose and nasal bones. 



The following fossil species probably belong to this genus : —

Cuvier (Oss. Foss. ii. p. 71, t. 9. f. 7) figures a fossil skull of a. 

 species of this genus from a drawing made at Milan by M. Adolphe

 teographie, t. 14, figure at left upper comer of the plate).
