^{page 380 note †} The Okapi's hairs, which I examined, are from a bandolier made from the skin from one of the legs of the animal (vide Sclater, P.Z.S., 1901). They are about 5 mm. in length, or about the length of the shoulder and side hairs in the Somali and Penrice's zebra, from both of which they differ in shape, tapering to a point much more gradually. In the relative development of the medulla and cortex they closely resemble equine hairs, differing entirely from the hairs of antelopes, goats, and deer.

^{page 381 note *} Since the above was written Professor Lankester has named this animal, which is called the Okapi, Ocapia Johnstoni, Dr Sclater having already supplied the specific name.
