Next there is the "onagra," "koulan," or "wild-ass" (_Asinus onager_), supposed to be the origin of the common kind.

This is a native of Asia, though it is also found in the north-eastern parts of Africa.

There is also the "dziggetai," or "great wild-ass" (_Asinus hemionus_), of Central and Southern Asia, and another smaller species the "ghur" (_Asinus Hamar_) found in Persia.

Again, there is the "kiang" (_Asinus kiang_) met with in Ladakh, and the "yo-totze" (_Asinus equulus_), an inhabitant of Chinese Tartary.
All these are Asiatic species, found in a wild state, and differing from one another in colour, size, form, and even in habits.

Many of them are of elegant form, and swift as the swiftest horses.
In this little book we cannot afford room for a description of each, but must confine our remarks to what is more properly our subject--_the wild-asses of Africa_.
