It is with regard to their horns that the two species chiefly differ from each other; for while the anterior horn of the Monoohoo has an average length of two or three feet, curving backward, that of the Kobaaba not unfrequently exceeds four feet, and is slightly pointed forward, inclining from the snout at about an angle of forty-five degrees. This rhinoceros is also the rarer of the two, and is only found in the more interior parts of South Africa.

The chief distinguishing characteristics of the white rhinoceros are its superior size, the extraordinary prolongation of its head, which is not far from one third of the whole length of the animal's body, its square nose (hence also designated "square-nosed rhinoceros"), and the greater length of the anterior horns.
