Ungulates: Hoofed Mammals. — This group includes the domesticated animals, as the horse, cow, sheep, and pig. A group of animals which originallj^ roamed wild, many species eventually came under the subjugating influence of man. Now they form a source of the world's wealth, and are an impor- tant part of the wealth of the United States. The order of ungulates is a very large one. It is characterized by the fact that the nails have grown down to become thickened as hoofs. In some cases only two (the third and fourth) toes are largely developed. Such animals have a cleft hoof, as in the ox, deer, sheep, and pigs. These form the even-toed ungulates. The deer fam- ily are the largest in number of species and individuals among our native forms, and in fact the world over. Among them are the common Virginia deer of the Eastern states, the white-tailed deer of our Adirondack forests. The bison, or buffalo, is nearly related to the deer and wild cattle. Formerly bisons existed in enormous Vixgiuia deer.
