Of these there are six or seven kinds--perhaps more.
First, there is the "wild-ass" (_Asinus onager_), which, as already stated, extends from Asia into the north-eastern parts of Africa, contiguous to the former continent.
Next there is the "koomrah," of which very little is known, except that it inhabits the forests of Northern Africa, and is solitary in its habits, unlike most of the other species.

The koomrah has been described as a "wild horse," but, most probably, it belongs to the genus _asinus_.
Now there are four other species of "wild-asses" in Africa--wild horses some call them--and a fifth reported by travellers, but as yet undetermined.

These species bear such a resemblance to one another in their form, the peculiar markings of their bodies, size, and general habits, that they may be classed together under the title of the _zebra_ family.

First, there is the true zebra (_Equus zebra_), perhaps the most beautiful of all quadrupeds, and of which no description need be given.

Second, the "dauw," or "Burchell's zebra," as it is more frequently called (_Equus Burchellii_).
