this animal is the excessively long neck (as shown in the accompanying figure), 
which has led to its being likened to a miniature giraffe. The horns of the bucks 
curve forwards at the tips in a peculiar hook-like manner, and are usually about 
13 inches in length, although they may reach 14 
inches. The skin of this antelope is distinguished 
by the presence of a very broad dark-brown band 
running down the middle of the back, which in its 
widest part measures some 7 or 8 inches across, and 
stands out in striking contrast to the rufous fawn of 
the flanks and limbs. 
The skull differs from those of the true gazelles 
by its extremely dense and solid structure, as well 
by the relative shortness of its facial portion, its 
remarkable straightness, and the unusually small 
size of the cheek-teeth. 
Captain Swayne says that “the 
gerenuk is found all over the Somali 
country in small families, never in large herds, and 
generally in scattered bush, ravines, and rocky 
ground. I have never seen it in the cedar-forests, 
nor in the treeless plains. Gerenuk are not neces¬ 
sarily found near water; in fact, generally in stony 
ground with a sprinkling of thorn-jungle. The gait 
of this antelope is peculiar. When first seen, a buck 
gerenuk will generally be standing motionless, head 
well up, looking at the intruder, and trusting to its 
invisibility. Then the head dives under the bushes, 
and the animal goes off at a long, crouching trot, 
stopping now and again behind some bush to gaze. 
The trot is awkward-looking, and very like that of 
a camel; the gerenuk seldom gallops, and its pace is 
never very fast. In the whole shape of the head 
and neck, and in the slender lower jaw, there is a marked resemblance between the 
gerenuk and the dibatag.” This antelope subsists more by browsing than by 
grazing, and it may not unfrequently be observed standing up on its hind-legs, 
with outstretched neck, and its fore-feet resting against the trunk of a tree, in 
order to pluck the foliage.

The Chiru, or Tibetan Antelope. 
Genus Pantholops. 
In addition to possessing a peculiar species of gazelle, to which reference has 
already been made, the elevated and barren plateau of Tibet is further characterised 
by an antelope remarkable for the swollen nose and long elegant horns of the bucks. 
This antelope is the chiru (Pantholops hodgsoni), the sole representative of the
