American Big Game in its Haunts 



found in the European Tertiary. The two exist- 

 ing species are African. 



In the western hemisphere swine are represented 

 by the peccaries, differing from them chiefly In 

 having six less teeth, one less accessory toe on the 

 hind foot, and in a stomach of more complex char- 

 acter. Peccaries also have the metapodial bones 

 supporting the two functional digits fused together 

 at their upper ends, forming an imperfect "cannon 

 bone," which is a characteristic of practically all 

 the ruminants, but of no other hoofed beasts. 

 One species only enters the United States along the 

 Mexican border. 



All non-ruminant ungulates have from four to 

 six incisors in the upper jaw; the canines are 

 present, and sometimes, as in the wart hogs, reach 

 an extraordinary size. 



Coming now to the ruminants, all digits except 

 the third and fourth have disappeared from camels 

 and llamas, and the nails on these are limited to 

 their upper surface without forming. a hoof, the 

 under side being a broad pad, upon which they 

 tread. No camel-like beasts have inhabited North 

 America since the Pliocene age. Chevrotains, or 

 muis deer ( Tragulid^) , are not deer in any true 

 sense, as they have but three compartments to the 

 stomach ; antlers are absent and In their place large
