Okapi \O*ka"pi\, n. [Native name on the borders of Belgian
   Kongo, possibly the same word as Mpongwe okapo lean.]
   A peculiar mammal ({Okapia johnostoni}) closely related to
   the giraffe, discovered in the deep forests of Belgian Kongo
   in 1900. It is smaller than an ox, and somewhat like a
   giraffe, except that the neck is much shorter. Like the
   giraffe, it has no dewclaws. There is a small prominence on
   each frontal bone of the male. The color of the body is
   chiefly reddish chestnut, the cheeks are yellowish white, and
   the fore and hind legs above the knees and the haunches are
   striped with purplish black and cream color.
