Mr. F. C. Selous, who did not include the Roi Rhébok amongst the species met with in his ‘Hunter’s Wanderings,’ published in 1881, subsequently obtained full particulars concerning this species, and has kindly favoured us with the following valuable notes:—
“The ‘Rooi Rhébok’ of the Boers is an inhabitant of arid stony hills, and wherever such hills are met with one may expect to find this handsome little Antelope throughout the Cape Colony, Natal, Zululand, the Orange Free State, the Transvaal, Bechuanaland, and the southern portion of the Bechuanaland Protectorate. In the west it does not range further north than Sichele’s country, and though plentiful in the parched-up stony hills scattered over the territory of that chief, it is unknown in very similar ground in Khama’s country, only a short distance further north; nor have I ever heard of its existence in any country to the north of the Limpopo River, and it is certainly unknown in Makalakaland, Matabeleland, and Mashunaland. In appearance the Red Rhébuck looks very much like a miniature Reedbuck, but on a close inspection, although the resemblance between the two species is very close, certain points of difference will be noted. Both species have a large fluffy tail, which they throw up when alarmed, exposing the white under surface; the shape of the ears is the same in both, and both have bare spots about the size of a sixpence an inch below the base of the ears. There is not much difference in the colour of the two species, and the distribution of white on the underparts of each is the same. The character of the horns in the two species is, however, different, for although the male Red Rhébuck has horns crooking forwards like those of a Reedbuck, a pair of Red Rhébuck horns do not look like a pair of Reedbuck horns in miniature. The minor points of divergence would be difficult to explain, though apparent enough on comparison of actual specimens; but the most important difference is the absence in the Red Rhébuck of the soft cushion at the base of the horn, which is always present in the Reedbuck. This soft gristly cushion covered with black skin, at the base of the horn above the eye, is found in no other Antelope but the Reedbuck, and is never absent in this species, nor does it ever disappear or turn into horn with age, being invariably found at the base of the horns of the oldest males. In the Red Rhébuck the hair grows close up round the base of the horn, as in all other Antelopes, with the exception of the Reedbuck. In both species the females are hornless, and in both the alarm-call is a shrill whistle. Although the Red Rhébuck is so similar in shape, coloration, and general appearance that it looks like a miniature Reedbuck, in its habits and mode of life it differs entirely from that species. The Reedbuck, as its name implies, loves the neighbourhood of rivers and lakes and swamps, and is never found far away from water. It does not occur in herds, but in small families, a male and female usually living together, the latter often accompanied by its last year’s kid. It is worthy of remark, however, that the Reedbuck though, as a rule, it is a dweller on level ground on the borders of rivers and lakes, in some parts of the country may often be found on stony ridges where these latter are in the immediate vicinity of rivers, as is often the case in Mashunaland. As the Red Rhébuck is not found in any of the countries between the Limpopo and the Zambesi, through which my various hunting expeditions have led me, my knowledge of these little Antelopes is not very extensive. However, whilst journeying slowly from Port Elizabeth to the Diamond Fields by bullock-waggon first in 1871, and for the second time in 1876, I saw a considerable number of them both in the hills of the Cape Colony and in those of the Orange Free State, and shot in all about a dozen specimens. More recently, in the early part of 1888, I searched for and found a good many Red Rhébuck in the arid hills near Sechele’s town[15], and secured the heads of three fine males for my collection. According to my experience the Red Rhébuck is usually to be met with in small herds of from three or four to fifteen animals, only one full-grown buck being with the herd, though a young male or two with horns not fully developed may also be present. Old males at certain seasons leave the herds and live alone, as is the case with all other gregarious Antelopes. The hills on which I found Red Rhébuck were of no great altitude, rising as a rule from 500 to 1000 feet above the surrounding country. Often they were flat or table-topped, with a precipitous cliff of 50 or 60 feet in height just below the table-like summit. In such cases I often found the Red Rhébuck lying in the bushes just at the base of these cliffs. Where arid stony hills, which they are known to frequent, are intersected by ravines, in which grow a certain amount of scrubby bush, Red Rhébuck will most likely be found in the neighbourhood of such ravines. In my experience these Antelopes are usually to be met with well up the sides and near the tops of the hills which they frequent, and are best hunted from the summit of the hill, as they always run upwards when alarmed. In the hills where I last hunted Red Rhébuck in Sechele’s country, there was absolutely no water whatever, and in the Cape Colony and the Free State the hills are also for the most part arid and waterless; so that these little Antelopes seem to be able to do without drinking water for several months in the year, as is the case with many other Antelopes in South-western Africa. I now forget the general colour of the Red Rhébucks I shot many years ago in the Cape Colony and the Orange Free State; but the three males I last shot in the Bechuanaland Protectorate were fawn-coloured on the head and neck, and dark grey on the upper parts of the body.”

The corresponding rings in the two pairs of horns are placed opposite each other.
The change of shape of the horns in the Antelopes as the animals grow older, so frequently referred to in this work, is well marked in the present species, and we have therefore thought it worth while to illustrate these differences by figures (figs. 41 and 42). Figure 41 represents the horns of a young, or rather just adult, male, in which they have attained a length of about 6¼ inches, and are evenly curved upwards to their slender points. Figure 42 shows those of an aged specimen, in which it will be seen that the sharp slender point has got more worn down, while at the same time a long straight basal portion has been added below. This change causes such a difference in the general appearance of the horns that authors have in many cases been led to suppose that the extremes represent different species. We therefore take the opportunity of pointing out how deceptive such appearances are, and how careful writers should be when they found species mainly on the characters presented by the horns. At the same time, the perfect identity of the curves in the part that is common to both specimens is very noteworthy, and shows how valuable horn-characters may be when skill and care are exercised in using them.
Our figure of this Antelope (Plate XLV.) has been taken by the kind permission of Mr. W. L. Sclater from a specimen of this species belonging to the South-African Museum at Cape Town, which had been sent home to Mr. Edward Gerrard of Camden Town to be mounted. It is an adult male and was obtained by Dr. D. R. Kannemeyer near Burghersdorp in the Cape Colony on the 28th May, 1894. The specimen stands about 27½ inches high at the shoulders, and the body from the nape to the rump measures about 29 inches. The tail is very bushy, and measures at least 9 inches to the end of the hairs. The bare spot beneath the ear is very observable. The general colour of the specimen is well shown in Mr. Smit’s figure.
