Zebra \Ze"bra\, n. [Pg. zebra; cf. Sp. cebra; probably from a
native African name.] (Zool.)
Any member of three species of African wild horses remarkable
for having the body white or yellowish white, and
conspicuously marked with dark brown or brackish bands.
[1913 Webster]
Note: The true or mountain zebra (Equus zebra syn. 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 Burchellii syn. Asinus
Burchellii or Equus quagga), known as Burchell's
zebra, plains zebra, and dauw, is the most
abundant, inhabiting the grassy plains of tropical and
southern Africa, and differing 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. Grevy's zebra (Equus
grevyi) is distinct from the others in being placed in
the subgenus Dolichohippus, whereas the plains and
mountain zebras are placed in the subgenus Hippotigris.
