[Illustration: Bisons in Battle.]
This family is easily distinguished from the other groups of
Hollow-horned Ruminants. It is composed of large, heavy animals, in
which the skin of the neck is loose and hanging, forming a large fold
called the dew-lap.
There are eight species found in this family—the American Buffalo or
Bison, the Musk Ox, the Cape Buffalo, the European Bison or Auroch, the
Yak, the Jungle Ox, the Common Buffalo of India, and the Common Ox, or
the well known group including our domestic Cattle.
