Size medium or small; build generally thick and clumsy; naked muzzle large; anteorbital glands opening into a row of pores, which form a long naked line on each side of the muzzle; crown of head tufted, so that the horns are often quite hidden in the hairs; tail short or medium, not heavily tufted; mammæ four; lateral hoofs well developed.
Skull with large lachrymal fossæ, but no fissure at the base of the nasals, and no large pits above or beneath the eyes; auditory bullæ divided by a septum; upper molar teeth short and broad; in the larger species with an additional column on the inner side.
Horns two, generally present in both sexes, short and spike-like, placed very far back on the head, on the ends of the posteriorly extended frontals; directed straight backwards nearly in the line of the profile, not twisted or curved; their bases often roughened or angulated.
Distribution. Africa south of the Sahara.
This genus, although large, and with species ranging in size from that of a small donkey down to that of a hare, is yet a very uniform and natural one, and shows remarkably little diversity among its members in essential characters. To sportsmen in general the majority of the species are little known, partly owing to their being too small to afford any sport and with but poor horns for trophies, but mainly owing to their inhabiting thick bush, so that they are hardly ever seen. One species, however, the common S. African Duiker, the popular name of which we have extended to all the members of the genus, is well known to every sportsman who has visited that country, both on account of its extreme abundance in most localities, and of its inhabiting more open districts than its congeners, the Bush-Duikers. It has allies in Abyssinia and Senegal, and the three have together been separated by some authors as a distinct genus, bat this separation we are not at present prepared to endorse.
Considering, then, all the Duikers as forming but one genus, we may distinguish them according to the following synopsis, although, as three or four of the species are known from very insufficient materials, we may expect that the characters will require some modification hereafter.
From the localities appended it will be seen that the large majority of the species are West African in habitat, the great tropical forest which covers so much of that part of Africa being apparently especially suited to their bush-loving habits.

Vernacular Names:—Bush-Goat of English at Sierra Leone (Afzelius); Mbimbi in Longobondo (Pechuel-Loesche, fide Matschie).
Size large; form stout and heavy. Ears short, broad, and rounded, their length much less than the distance from eye to muzzle. Fur very short on the fore-quarters, longer on the hind back, but in adults worn off and showing the whitish underfur or naked skin round the base of the tail. General colour all over, of face, body above and below, and of limbs, dark blackish brown. Crest orange or rufous, little developed in youth, and again wearing off in old age. Muzzle, cheeks and chin, and extreme tips of ear whitish. Lumbar region with a broad pale yellowish mesial stripe running from the middle of the back on to the loins.
In extreme youth the hairs of the posterior half of the body are all tipped with white, except just along what becomes afterwards the pale lumbar stripe, where they have long blackish tips, entirely hiding the white; and the caudal region, afterwards whitish and partly naked, is clothed with long black hairs.
Skull, in proportion to the size of the animal, delicate, slender, and elongate. Muzzle slender, tapering, not laterally swollen between the premolars and the anteorbital fossa. Anteorbital fossæ of medium depth. Mesial notch of palate surpassing anteriorly the lateral ones by about half an inch, these latter comparatively deep and V-shaped.
Horns long and tapering, lying back in or below the line of the nasal profile, rather bowed downwards terminally. Divergent, slender, evenly tapering, but little roughened at base; those of male and female almost precisely alike, except that the latter are slightly smaller. Length (♂) 6·4 inches; basal diameter going about 5 or 5½ times in the length.
Dimensions:—♀. Height at shoulder 34 inches, ear 4, hind foot 13·5.
Skull (♂): basal length 10·3 inches, greatest breadth 4·9, muzzle to orbit 6·5.
Hab. West Coast of Africa, from Liberia to Angola.
We commence our history of this numerous group of Antelopes, for which we adopt the term “Duiker” (i.e. “Diver”), originally given by the Boers of the Cape to C. grimmi, as a vernacular name, with two species readily distinguishable from the remainder by their greater size, but not apparently otherwise divergent in structure. These are the Yellow-backed Duiker and Jentink’s Duiker.
The eminent Swedish naturalist, Adam Afzelius, a pupil of Linnæus, and subsequently editor of his master’s autobiography, resided for two years (1792–94) on the West Coast of Africa, as botanist to the Sierra Leone Company. Amongst numerous papers embracing the results of his researches on the West-African fauna and flora, he published in 1815, in the ‘Nova Acta’ of the Royal Society of Sciences of Upsala, a learned treatise on Antelopes generally, and specially upon those of Guinea. In the course of this memoir he described and figured for the first time the present species, calling it Antilope silvicultrix, as being the “Bush-Goat” of the colonists. Afzelius speaks of it as not uncommon in the hills round Sierra Leone, particularly in the districts adjoining the rivers Pongas and Quia. Here it is not met with among the rocks, but inhabits the lower tracts of the bush, either solitary or, in the rutting-season, in pairs, and occasionally in small herds. It hides itself in the bush by daytime, but comes out in the early morning to feed in the open spaces, where the hunters lie in wait for it. Its flesh is stated to be much esteemed as food, although it has a strong musky scent, particularly at certain seasons of the year.
After Afzelius subsequent authors were for many years content to copy his notes and description, and we get no further information on the subject till we come to 1850, when the species was figured in the ‘Knowsley Menagerie’ by Waterhouse Hawkins from specimens living in that magnificent collection. In this set of drawings it appears twice—first on plate viii. fig. 1 (erroneously named Cephalophus punctulatus), which seems to have been taken from a young individual of this Antelope; and secondly on plate xxiii. fig. 3, as Cephalophus sylvicultrix, in which the adult, or at any rate a more advanced stage, is represented. At the date of the sale of the Knowsley Menagerie in 1851 it does not seem that any specimens of this Antelope were left in the collection; but a young example, no doubt one of those that died in the Menagerie, had been presented by Lord Derby to the Zoological Society of London, whence it subsequently passed into the collection of the British Museum. From the labels on this and other specimens we learn that they were obtained by Whitfield, a well-known collector formerly in the employment of Lord Derby, at Sierra Leone.
Little further information respecting this species is available until 1870, when the Zoological Society, on March 24th, purchased a single living example of it from Cross of Liverpool, as recorded in the Society’s ‘Proceedings’ (P. Z. S. 1870, p. 220). This animal, however, did not live long in the Society’s Menagerie, as it died on the 14th July of the same year. Its body was disposed of to Mr. E. Gerrard, jr., by whom it was stuffed and sold to the Melbourne Museum.

The only modern authority that speaks of this Antelope is Mr. Büttikofer, of the Leyden Museum, who made two zoological voyages to Liberia in 1880 and 1886. In Dr. Jentink’s list of the Liberian mammals obtained by Mr. Büttikofer and his fellow collectors in Liberia (Notes Leyden Mus. vol. x. p. 20) it is recorded that Cephalophus sylvicultrix is said to occur sparingly on the Jackson and Mahfa rivers in that country, but to be more common on the Manna and Solyman rivers. But Mr. Büttikofer, in spite of all his efforts, did not succeed in obtaining specimens.

Although, as already stated, originally discovered in Sierra Leone, the Yellow-backed Duiker seems to have a somewhat extended distribution along the western coast of Africa, reaching altogether from Liberia to the Congo. A pair of mounted specimens and a skeleton in the British Museum were transmitted from Fantee by the native collector Aubinn. The same collection also contains skins from Lagos, procured by Sir Alfred Moloney, and two skulls and a skin from Gaboon, brought to England by Mr. DuChaillu on his return from his celebrated gorilla-hunting expedition. Upon one of these skulls in 1865, Dr. Gray established his Cephalophus longiceps, and upon the second skull and the skin which accompanied it, in 1871, the same author based his C. melanoprymnus. Thomas has shown (P. Z. S. 1892, p. 416) that both these names are merely synonyms of, C. sylmcultrix[12]. We may add we have as yet no information as to the range of this species into the interior, except that Herr Matschie has recorded its occurrence in Togoland; but it must be explained that our knowledge of the distribution of West-African mammals is still woefully deficient. As the same gentleman informs us, there is, besides several skins from Togoland, a stuffed example in the Berlin Museum sent by Herr Pechuel-Loesche from Longobondo.
Our illustration of this species on Plate XIII. is copied from a watercolour drawing taken in April 1894 by Keulemans, from a fine male specimen living in the Zoological Gardens of Rotterdam. As this animal was received from the Congo in June 1891 (presented by Heer A. de Bloeme) it must be necessarily quite adult. Mr. Keulemans’ notes on it are as follows:—“Head dark grey; neck grey, shading into brownish and becoming blackish near the shoulders; hairs of neck and head very short and glossy; general colour dark brown, with a bluish gloss, getting blacker on the buttocks, where the hairs are long; tail short and black; large plaque on the back and buttocks and tuft between the horns brownish ochre.” Our second figure (Plate XIV. fig. 2), which was prepared by Mr. Smit under Sir Victor Brooke’s directions, probably represents a young male of this species; but we do not know for certain from what specimen it was taken. The figure of Gray’s C. melanoprymnus in the Zoological Society’s ‘Proceedings’ for 1871 (pl. xliv.) was drawn from a still younger animal, probably of about the same stage as the figure of “C. punctulatus” in the ‘Knowsley Menagerie.’ It will be observed how greatly the colour of the back varies in these specimens of different ages.

Cephalophus jentinki, Thos. P. Z. S. 1892, p. 417; Lyd. Horns and Hoofs, p. 213 (1893).
Size large, though smaller than C. sylvicultrix; form stout. Ears short, broad, and rounded. Colour of head, ears, neck all round as far back as the withers, throat, and a narrow sternal line deep uniform black; of body above and beneath coarsely grizzled grey, the hairs ringed with black and white. Lips and chin, a line all round the fore-quarters separating the black from the grey, axillæ, groins, fore and hind legs whitish; a rather darker mark running across the outer side of the forearm.
Skull much longer in proportion to the size of the animal than in C. sylvicultrix, agreeing, in fact, precisely in size with that of the larger species. In other respects also it agrees so closely with that of C. sylvicultrix that, had the external characters not been known, the two species would have been hardly supposed to be different. Such differences as there are, however, have been fully pointed out in Thomas’s monograph.
Horns long, tapering, placed in the line of the nasal profile, divergent as in C. sylvicultrix, those of female 6·1 inches long, base not specially thickened, basal diameter going about 5½ times in the length.
Dimensions:—♀. Height at withers 30 inches, ear 4, hind foot 12.
Skull (♀): basal length 10·5 inches, greatest breadth 5, muzzle to orbit 6·5
Hab. Liberia.
The present Duiker nearly equals the preceding species in size, but, as will be seen by the Plate, is immediately distinguishable by marked differences in colour, its black head and neck rendering it very conspicuous. Its discovery is due to Mr. F. X. Stampfli, a naturalist who made two expeditions to Liberia, in 1884 and 1886, to collect specimens for the Leyden Museum. In the first of these he was alone; in the second he was accompanied by Mr. Büttikofer, the well-known Conservator of that institution.
The Black-headed Duiker was first described by Dr. Jentink, the Director of the Leyden Museum, in 1885, from a single female specimen procured near Schieffelinsville, on the Junk River, by Stampfli in the preceding year. Unfortunately Dr. Jentink referred the specimen to C. longiceps of Gray, a species based on a skull brought home from Gaboon by Mr. DuChaillu. In doing this he was perfectly justified, on account of the extraordinarily close resemblance of its skull to that of C. longiceps. But Thomas subsequently showed that DuChaillu’s Gaboon skull (as already mentioned above) is undoubtedly referable to the nearly allied C. sylvicultrix. Under these circumstances it became necessary to give another scientific name to the present species, and Thomas selected the appropriate term jentinki; as it was Dr. Jentink’s “carefulness, led astray by Dr. Gray’s serious mistakes,” that had “caused him to make the venial error just referred to.”
During his second expedition, in 1887, Mr. Stampfli procured two more examples of this Antelope on the Farmington River. Like the first, both these were females, and, as we are told by Dr. Jentink, do not differ in colour from the typical specimen. Mr. Stampfli’s notes on this Antelope are as follows:—
“A little below Schieffelinsville, in the triangle between the Junk River on one side and its two confluents, the Du Queah and Farmington Rivers, on the other, a wooded eminence called ‘Sharp Hill’ rises in the middle of the marshes, to which, according to the testimony of the natives, these animals are restricted. As in the dry season the marshes cannot be traversed in canoes, and yet are not sufficiently dry to be passed on foot, these Antelopes can only be obtained in the rainy season, and it is said to be quite an exception for a specimen to be procured except during that period.”
In the second volume of Mr. Büttikofer’s ‘Reisebilder aus Liberia,’ which contains a complete account of the explorations and discoveries of himself and his companions in that country, will be found some additional details on this Antelope. Mr. Büttikofer calls particular attention to the large size of the inguinal glands between the belly and the thigh in this Antelope. They are so large that they will easily contain a lemon. These are said to be fat-glands, from which the beast extracts fat with its muzzle to lubricate its short, shining, hairy coat. Mr. Büttikofer also says that this Antelope, although only obtained from Sharp Hill, certainly occurs in other parts of Liberia.
Our figure of this Bush-Duiker (Plate XV.) has been prepared by Mr. Smit from the mounted specimen in the British Museum, which is the type of the species. It is one of the three specimens obtained in Liberia by Mr. Stampfli, the other two remaining at Leyden. We believe that these are the only three specimens of this rare Antelope existing in any European museum.

Size comparatively large. General colour dusky chestnut-brown without spots or bands, and not lighter on the belly. Forehead dusky brown, like body; chin and throat pale greyish brown. Hairs of crest chestnut-red at the base, and tipped with black: mingled with them are some hairs which are dusky throughout, and others pure white. Anterior surfaces of the legs somewhat lighter than the posterior surfaces. Tail dusky, except at the tip, where there are a few pure white hairs.
Skull elongate; muzzle slender; frontal region strongly convex.
Horns “directed backwards, and lying below the plane of the upper surface of the skull”; those of male 4½ inches long; slender, straight, not thickened at the base in front.
Dimensions:—♂. Head and body 38 inches, ear 4¼, hind foot (hoof to hock) 9½.
Skull: basal length, from occipital condyle, 8·5 inches; greatest breadth 4; nasals, length 3·7.
This description has been compiled from Mr. True’s two notices and from his figures of the animal and its skull, as we have not as yet had any opportunity of seeing examples of the species, of which no specimen has come to Europe.
Hab. East Africa, Mount Kilimanjaro, at high elevations (Abbott).
We now proceed to consider the smaller Duikers of the section with horns slanting backwards. These are generally of a rufous colour, varied by more or less intense dark markings on the face and dorsal line, only C. doriæ, which we place by itself, having the back transversely barred.
Sir John Willoughby’s volume on ‘East Africa and its Big Game’ gives an excellent account of the adventures of himself and a party of friends during a shooting-expedition to the hunting-grounds of Kilimanjaro and its neighbourhood, and of the great variety and enormous quantity of the larger mammals to be met with, a few years ago, in that district. In an appendix to the volume, contributed by Mr. H. C. V. Hunter, F.Z.S., is added a systematic account of the principal mammals met with on the plains round Kilimanjaro and on the mountain itself, amongst which we find recorded such splendid Antelopes as the Eland, Koodoo, Oryx, Hartebeest, Gnu, Pallah, Waterbuck, Reedbuck, and three kinds of Gazelle. At the close of the list Mr. Hunter notes the occurrence, high up on Kilimanjaro, of a species of Cephalophus “of a dark red colour, much larger than the Common Duiker (C. grimmi). A male of this probably new Antelope, it is stated, had been killed by Dr. Abbott.” This, so far as we know, is the first published mention of the species of which we now speak as Abbott’s Duiker.
Dr. W. L. Abbott, who is thus alluded to, is an American naturalist and explorer who passed nearly two years, in 1888 and 1889, collecting objects of natural history in the district of Kilimanjaro. On his return to America Dr. Abbott presented his whole collection to the National Museum, which is under the charge of the Smithsonian Institution at Washington. Mr. Frederick W. True, the Curator of the Department of Mammals, to whom was assigned the task of describing the collection, speaks of it as “one of high scientific value.” “The specimens,” he says, “have been prepared with much care, the skins being almost invariably accompanied by the skulls, and furnished with labels giving the locality and date of capture, the sex, and other data.” It included altogether about ninety skins and an equal number of skulls representing some thirty-eight species. Amongst these was a single male example of the present Antelope, no doubt the specimen alluded to by Mr. Hunter which is stated to have been killed at a high altitude on Kilimanjaro. As there is no specimen of this Antelope available for our use, we have, as already stated, extracted the more essential characteristics from Mr. True’s two accounts.
Mr. True was of opinion that C. spadix is closely allied to C. niger, and even possibly identical with it. We think, however, that its nearest relatives are probably C. natalensis and C. harveyi, from which it is at once distinguishable by its larger size.

The Natal Duiker, which is perhaps a southern representative of the next species, is, like it, of a nearly uniform bright bay colour, rather paler below, and with some inconspicuous darker markings on the vertical crest. Our figure of this species (Plate XVI.) was put on the stone by Mr. Smit from a sketch prepared by Mr. Wolf, and was probably taken from one of the specimens in the British Museum; but of this, we regret to say, there is no certain record.
The discovery of the Natal Duiker is due to Sir Andrew Smith, who met with it in the forests of Natal and first described it in 1834 in one of his articles on African Zoology published in the ‘South African Quarterly Journal.’ Sir Andrew afterwards figured it in the volume of Mammals of his ‘Illustrations of South African Zoology,’ where the following notes are given on its habits:—“Both C. cæruleus [= C. monticola, nob.] and C. natalensis inhabit the African forests; the former towards the Cape of Good Hope, the latter to the eastward about and beyond Port Natal. They both feed partly upon the grass which occurs among the underwood, and partly upon the young leaves and shoots of the brushwood and small trees which exist in the situations they inhabit; and to obtain the latter they may occasionally be seen scrambling among shrubs, or ascending the stems of sloping trees, so as to reach what they cannot attain while they are on the ground.”
Beyond a reference to its name in various lists and catalogues, we find little more recorded concerning this Antelope until modern days, when several experienced observers have mentioned it. In his ‘Rough Notes on the Game and Natural History of South and South-east Africa,’ published in 1875, the Hon. W. H. Drummond mentions the “Red-buck,” as he calls it, as one of the two species of Cephalophus that inhabit the jungles of Natal, the other being “the Blue-buck” (Cephalophus monticola). Of these, Mr. Drummond says the Red-buck “is the larger and also the least common. It is, as its name denotes, of a light yellowish-red colour, mingled with grey on the lower parts, and its chief peculiarity is a tuft of hair growing out of the forehead, which gives a curious appearance to the hornless does, while it partially conceals the small horns of the bucks. Its flesh is anything but good, and it is difficult to shoot, from the tremendous rushes it makes when disturbed. So fast and heedlessly does it run, that I once saw a buck, that had passed me while I was loading, entangle itself in a mass of creepers, from which, despite its struggles, it was unable to escape until I released it with the help of my knife. It was quite uninjured, and I kept it in confinement for some weeks, but, like most Antelopes when caught full-grown, it ultimately pined away and died.”
Messrs. Nicolls and Eglington, in their ‘Sportsman in South Africa’ (1892), tell us that this Antelope is found only in Zululand, Natal, and the southern portions of Swaziland, but is everywhere very scarce. It is, however, stated on good authority to have been found recently in South-eastern Mashonaland. In habits, these authors say, it resembles the Common Duiker, except that it chooses dense forest as a residence.
So far as we know, but one specimen of the Natal Duiker has ever been brought to Europe alive. This was a male which was purchased in 1880 (March 14th), by the Zoological Society of London, of Mr. Charles Jamrach, for the sum of £6 10s., and lived some months in the Menagerie.
Besides the skin of an adult female of this species, received from Sir Andrew Smith as the type of C. natalensis, there is a mounted pair in the National Museum, collected by Dr. A. Krauss, and received in exchange from the Stuttgart Museum. There are also skins of adults of both sexes and accompanying skulls in the same collection from the Transvaal, obtained by Dr. Percy Rendall, C.M.Z.S., in 1893 and 1894. Dr. Rendall has kindly favoured us with the following notes upon the present species of Duiker:—
“The local Colonial name for this Antelope is the ‘Lesser Red-buck.’ To the Swazis it is the ‘Incumbi,’ and to the Shangaans the ‘Mangule.’
“Its occurrence I found confined to a very limited area, i.e. the slopes of the Makongwa Mountains, which are locally termed ‘Moodie’s Concession,’ in the Barberton portion of the Transvaal, adjoining Swaziland. Here it was not uncommon in places; its resorts being always the wooded creeks or ‘dongas,’ where there is dense cover.
“Its habits are so skulking that it is extremely hard to procure specimens, even when the hunter is aware of its existence in a particular locality. Nothing but a well organized beat with natives and dogs will make these animals break cover from the bush and long grass they frequent.
“I never heard of one being seen or shot in the open, and their spoor and droppings are only seen just on the outskirts of the cover, where they feed at night.
“The way in which they double and dodge the dogs and beaters in full cry is inimitable, and to an onlooker is most entertaining. Their vitality is wonderful, and their power of endurance before dogs considerable, especially considering their comparatively small size. There is little difference between the respective weights of the sexes when adult, as I was surprised to find when I put them into the scale.
“The female is always horned, and in two specimens that I dissected each was found to be carrying a quarter-grown (hairless) fœtus, in the month of April. A wounded animal that I saw pulled down by a dog gave vent to a prolonged squeal, not unlike a rabbit or hare does under similar circumstances, though fainter in volume.
“The long tuft of hair around and between the horns is always more marked in the male, and practically masks the horns. The flesh is not appreciated by a European palate, though the reverse is the case with the Swazis, as I have noticed.
