Extract

The taxonomic value of hair has long been recognised. The different types of human hair have been made use of as a basis for classification of the varieties of Man by Primer Bey and many others, while Waldeyer in his Atlas has described briefly the hair characters of well known members of the Mammalian orders. In the present paper it is proposed to deal with hair within the limits of a single family, that of the Equidæ, and to describe certain peculiarities in the hairs of members of that group, which the author is of opinion are probably of specific value. But before dealing with the hair characters by which the species may be distinguished from one another, something must be said about those of the group as a whole.

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.
