Other Species. 
The South African antelope known as the roi rhebok {0. lalandi), 
which, by the way, must not be confounded with the true or vaal 
rhebok, is a smaller but nearly-allied species, standing only about 28 inches at the 
shoulder. It has long and coarse reddish-brown hair on the upper-parts, while 
beneath it is white. The horns are seldom more than 8 or 9 inches in length, and 
bend forwards in a sharp sweep, without any outward inclination. The West 
African nagor ( 0. redunca ) is closely allied to, if not identical with, this species; 
the coloration being similar, and the small horns not usually exceeding 6 inches in 
length. The other representative of the genus is the bohor ( C . bohor), extending 
in East Africa from Abyssinia to Masailand; it is a larger and brighter-coloured 
animal than the last, from which it is also distinguished by certain characters of 
the skull.

Genus Cobus. 
The antelopes included in the genus Cobus are water-loving animals, generally 
of larger size than the reitbok, and associating in herds. Their horns are long, 
sublyrate, and ringed nearly throughout; the tail is longer than the reitbok, and 
tufted at the end. As in the latter, the gland below 
the eye is rudimentary; and the colour, with the excep¬ 
tion of some patches on the rump and the head is uniform. 
The muzzle is naked. The skull may be distinguished 
from that of Cervicapra by the premaxillary bones 
reaching upwards to join the nasals. 
The water-buck (C. ellipsipry mnus) 
stands upwards of 4 feet or more at the 
withers, and is characterised by its long and very coarse 
hair, which varies in colour from reddish brown to dark 
grey, with an oval ring of white on the buttocks, extend¬ 
ing above the tail, a white gorget on the throat, a streak 
of the same colour on part of each eye, and some white 
near the muzzle. Good horns average about 28 inches 
along the curve, but they may measure 30, 31, or even 
33J inches; their colour is pale. Water-buck inhabit 
Southern and Eastern Africa to some distance north of 
the Zambesi; and they are never found in herds of more 
than twenty individuals. Mr. Selous states that the 
water-buck is most partial to steep stony hills, and is 
often found at a distance of more than a mile from the 
nearest river, for which, however, it always makes when 
pursued. Though a heavy-looking beast, it can clamber with wonderful speed and 
sureness of foot up and down the steepest hillsides. In Nyasaland Mr. Crawshay 
writes, that water-buck are always found in greatest numbers on large swampy 
plains overgrown with coarse grass, tall reeds, and papyrus, where in the wet 
season it is almost impossible to get at them; unlike other antelopes, except the 
HEAD OF WATER-BUCK.-
