Horns bent posteriorly, angular and rough. 



96. CAPRA. Goat. With a beard. C. hircus. 



97. Ovis. Sheep. Without a beard. O. aries *. 



b. Cone solid. 



98. ANTILOPE. Antelope. Horns annulated and spirally 

 twisted. 



99. RUPICAPRA. Chamois. Horns smooth. Capra 

 ruplcapra^ LIN. To this genus must be provisionally add- 

 ed the Nyl-ghaw (Phil. Trans. 1771, p. 170. tab. v!) and 

 Gnu. The ruminating animals all possess, in an exquisite 

 degree, the sense of smell. This has frequently been ob- 

 served of cows, sheep, goats, and the nyl-ghaw. 



B. Horns simple, formed of bone.

 HEAD, it is asserted, that the hybrid produce of the sheep and goat is fer- 

 tile, black-faced, and differs little in form from the black-faced sheep. The 

 intercourse is stated to be common. Vol. xi. p. 66.
