170 CLASS MAMMALIA. 



no further observation : the animals included are, as far as 

 they are known, exclusively American, and confined to its 

 northern latitudes. By the singular structure of their 

 horns, which have an anterior branch, and a prolonged 

 posterior point turned down into a hook, there is a simili- 

 tude though no affinity with the Deer ; which is further 

 evinced by pearly rugosities, shewing like incipient addi- 

 tional branches, by a white space on the rump, and a short 

 tail. They are exceedingly swift, living in small families 

 upon the hills below the high mountains, and above the 

 low lands along the Upper Missouri, round Hudson's Bay, 

 and, probably, to the extreme verge of the north-western 

 coast of Nootka, and Behring Straits ; they might be looked 

 for on the north-eastern shores of Asia, but although the 

 Argali has spread to both Continents, it does not appear 

 that this, the A. Lanigera or the Musk Ox, have yet been 

 observed alive in that quarter of the world. 



In the Journal of M. Le Ray, an account appears of the 

 mode adopted by the Sioux Indians in hunting these ani- 

 mals. He says, " that being with the hunters on the river 

 Jaune, in pursuit of the Cabree, as they are termed by the 

 Canadians, the party selected for the sport a hill, the as- 

 cent of which was gradual, but the opposite precipitous: at 

 the bottom of the slope they formed a chain of hunters, and 

 crawled gradually and simultaneously towards the summit, 

 slowly inducing the game to approach the precipice. When 

 arrived at a convenient height, they all suddenly rose and 

 gave a loud yell, which terrified the timid creatures so 

 completely, that most of them sprang over the brink, and 

 were dashed to death in their fall. Upwards of sixty Ca- 

 bree and big-horned sheep being thus slain in a single beat." 



The Prong-horned Antelope. (A. Furcifer.) In the 

 general aspect of this animal there is a resemblance both 

 with the Chamois and the Roebuck, though it is larger
