STRUCTURE OF FOOT IN EVEN- AND ODD-TOED UNGULATES. 



Sp., Radius; E., ulna; Hw., carpal bones; M., metacarpal bones; II. to V., digits, 

 1, 2, 3, phalanges. The figures show how the metacarpal bones are more and more united, 

 and the lateral toes more and more reduced. 



Sub-Order I : Non-Ruminants (A. non-ruminantia). 



All three kinds of teeth developed in both jaws, the canines often 

 enlarged into powerful tusks. Do not chew the cud, or ruminate. 

 Horns or antlers absent. Body stout. The skin only sparingly pro- 

 vided with hairs or bristles. A considerable layer of fat frequently 

 present under the thick skin. 



The European Wild Boar (Sus scrofa). 



(Length up to about 6J feet ; height up to shoulders about 3 feet ; 

 weight up to about 400 pounds.) 



The wild boar prefers for its habitat swampy forest thickets, which 

 are avoided by all other native mammals. Hence it is hardly surprising 

 that in the structure of its body this animal exhibits marked differences 

 from all the other habitants of the forest.
