* The true or mountain zebra (Equus, or Asinus, zebra) is nearly white, and the bands which cover the body and legs are glossy black. Its tail has a tuft of black hair at the tip. It inhabits the mountains of Central and Southern Africa, and is noted for its wariness and wildness, as well as for its swiftness. The second species (Equus, or Asinus, Burchellii), known as Burchell's zebra, and dauw, inhabits the grassy plains of South Africa, and differs from the preceding in not having dark bands on the legs, while those on the body are more irregular. It has a long tail, covered with long white flowing hair.
