Rh Peramelidæ—a family made up of creatures none of which much exceed the hare in size, and which, instead of feeding on vegetable substances (as do the kangaroos), eat insects, for which food they are well adapted by the sharp points and ridges which may be seen on their back teeth.



One member of this family, Chæropus (Fig. 8), is very exceptional in the structure of its hind-feet, which out-kangaroo the kangaroo in the
