The Guib (_fig. 156._) is an animal, which, though not noticed by any
naturalist or traveller, is very common in Senegal, from whence M.
Adanson brought over some of their skins. It resembles the gazelles,
especially the nanguer, in the size and shape of its body, in the
fineness of its legs, in the form of its head and muzzle, in the eyes
and ears, in the length of its tail, and by the want of a beard but
every gazelle, especially the nanguer, has the colour of the belly
white, while the breast and belly of the guib are of a deep brown. It
also differs from the gazelles in the horns, which are smooth, without
annular prominences, and have two longitudinal ridges, the one above
and the other underneath, forming a spiral twist from the base to
the point; they are also a little compressed. In these particulars
the guib is more like the goat than the gazelle, nevertheless it is
neither the one nor the other, but rather an intermediate species.
It is also remarkable for white stripes on a brown ground, that are
disposed along and across the animal's body, as if it were covered with
a harness. It is a gregarious animal, and they are found in numerous
herds in the plains of Podor.
