133. THE DERBIAN ELAND.
TAUROTRAGUS DERBIANUS (Gray).
[PLATE C.]

Exact height at withers unknown, but probably equal to, if not exceeding, that of the preceding species (70 inches). Forehead covered with hair of a rich ruddy-brown hue, extending from the base of the horns to a point below the level of the eyes; nose black; sides of the head dusky brown or dark fawn; a whitish stripe running inwards and forwards from the inner edge of the eye on each side; upper lip and chin white. Ears large and expanded, much larger than in the other species; the margins broadly white in front and ornamented on the lower side with a large black patch; the posterior surface mostly black, brownish at the base. Neck covered with long hair of a dark brown or black colour, blacker towards the shoulder than in front; base of the neck bordered by a white collar, directed obliquely upwards and backwards at least halfway up to the withers. Body of a rich ruddy fawn-colour, becoming paler or nearly white below, the middle of the belly black; a broad black stripe of longer hairs extending all down the spine from the neck to the root of the tail; sides of the body and haunches ornamented with thirteen or fourteen narrow white stripes, commencing at the dorsal stripe above and gradually fading away on the lower part of the belly and hind-quarters. Legs down to the knees and hocks of the same colour externally as the body, whitish on the inner side; there is a large black patch on the fore leg above the knee on the posterior and inner sides. Horns very large and massive, diverging from the base, the divergence in some cases amounting almost to a right angle; length of horns up to about 34·25 inches.

Female. Smaller than the male, and without the mat of hairs on the forehead; horns smaller and less divergent than in the male, but much more strongly twisted and crested than in the females of the other species.

Just as the Kudu, which is spread over the greater part of southern and eastern Africa, has a smaller relative (the Lesser Kudu) confined to Somaliland, so the Eland, which has a still wider range, has a near, but quite distinct, ally in a limited part of western Africa. But in the latter case the ally is what is called a “representative form,” since the typical Eland does not occur in the same country, whereas in Somaliland both the Greater and Lesser Kudus are found together in one district.

The discovery of the West-African Eland is due to the researches of the collector, J. Whitfield, who was employed by the thirteenth Earl of Derby to procure living specimens of the larger Antelopes and other animals for his celebrated Knowsley Menagerie. With this object Whitfield made several expeditions to the River Gambia, and on his return, in 1846, brought with him some horns of a large Antelope nearly resembling those of the South-African Eland, but “larger, longer, and much heavier.” In his expedition of 1847 Whitfield succeeded in procuring from the same district the upper part of the skull and horns of a male and the flat skins (unfortunately without heads or feet) of an adult male and female of this animal, of which the native name was said to be “Gingi-ganga.” It was upon these specimens that the late Dr. Gray, in October 1847, established his species Boselaphus derbianus, by publishing a short description of it in the ‘Annals and Magazine of Natural History’ for that month. It has been imagined, and even stated in print, that living specimens of this Eland were received by Lord Derby; but such, we believe, was not the case. The drawings made by Waterhouse Hawkins, and subsequently issued in the ‘Gleanings from the Knowsley Menagerie,’ were taken, we believe, not from living examples, but from the specimens brought home by Whitfield, as already mentioned.

So far as we know, no further information respecting this remarkable Antelope was brought to Europe until 1863, when the well-known African traveller, the late Mr. Winwood Reade, returned to England from one of his expeditions into Western Africa. Along with other spoils of the chase, Reade brought with him a head and skin of the present Antelope, which he at first believed to be undescribed; but on inspecting them, at Reade’s request, Sclater at once recognized them as belonging to the little-known Derbian Eland, and persuaded Reade to exhibit them at a meeting of the Zoological Society of London in May of that year. Reade’s notes upon this occasion were subsequently published in the Society’s ‘Proceedings’ and illustrated by a plate drawn by Joseph Wolf from Mr. Reade’s specimens. So little is known of this most interesting Antelope, that we propose to give Mr. Reade’s account of it at full length as follows:—

Some further details on the subject will be found in Winwood Reade’s ‘Savage Africa,’ where they are accompanied by a beautiful lithographic plate representing a herd of Derbyan Elands, drawn by Joseph Wolf and signed with his initials. This plate (fig. 119, p. 218) by the kindness of Messrs. Smith, Elder, & Co., we are enabled to reproduce in the present work.

Since Winwood Reade’s visit to the West Coast, although several heads of the Derbian Eland have been obtained at the Gambia by Dr. Percy Rendall and others, little additional information has been received on the subject. In 1898 Sir R. B. Llewellyn, K.C.M.G., the Governor of the Colony, brought home, amongst other spoils of the chase, a fine pair of horns of this Antelope, which were exhibited by Sclater at a Meeting of the Zoological Society on May 5th of that year. A figure of them was given in the ‘Proceedings,’ which the kindness of the Society enables us to reproduce (fig. 120, p. 219) on the present occasion. These horns are of large dimensions, measuring 31 inches in length from the base in a straight line, and about 11½ inches round their bases. They are apparently those of an adult male animal.

Mr. J. S. Budgett, F.Z.S., who made a zoological expedition to the Gambia last year, specially with a view of collecting and observing the river-fishes, has favoured us with the following notes on what he saw of the Derbian Eland during several visits to the upper districts of the Protectorate:—

Before concluding our account of the Derbian Eland, it is necessary to say a few words respecting the supposed new species of Eland described by M. Rochebrune in the ‘Bulletin’ of the Société Philomathique of Paris in 1883, and subsequently in his ‘Fauna of Senegambia,’ although we are not generally willing even to allude to this most untrustworthy publication. So far as we can make out, the specimens of this animal promised in the text of M. Rochebrune’s work to be sent to the Gallery of the Museum of Paris have never reached that Institution, and the only evidence we have, therefore, for its existence is contained in M. Rochebrune’s descriptions and figures. As well as we can judge from these and from the extreme improbability of there being a species of Eland in Senegal different from that of the Gambia, we are inclined to place the so-called Oreas colini as a synonym of the present species. The figure of the head given by Rochebrune is stated to have been taken from a sketch made by “M. le Dr. Colin” of a head of this animal obtained in the forest of Kita in Senegal. In this figure the whole head of the animal is represented as of a nearly uniform slaty grey, with the exception of a patch of reddish hair on the forehead at the base of the horns and a black patch in the middle of the nose. These are certainly striking differences, if we could trust them as being accurate, but we do not know how far M. le Dr. Colin’s sketch was correctly made, nor what alterations the copier of it may have introduced into M. Rochebrune’s plate. We cannot admit the existence of the supposed new species upon such unsatisfactory evidence.

The authorities of the Liverpool Museum have most kindly sent up to us for examination the specimens of the Derbian Eland now in the Derby Museum, Liverpool, which are probably those from which the original figures in the ‘Gleanings’ were drawn by Waterhouse Hawkins. The frontlet is apparently that of an adult specimen, as will be seen from our view of it (fig. 121, p. 221) prepared by Mr. Grönvold. The horns measure 30½ inches in length from base to tip, the tips are nearly 23 inches apart in a straight line. The two flat skins which accompany it are without heads, and the legs have been cut off at the knees.

In the British Museum there are frontlets of one female and two male specimens of the Derbian Eland, obtained at the Gambia by the same collector (Whitfield) and presented by Lord Derby. In the same collection there is a flat skin brought home by Winwood Reade, and the head of a female, dried with the skin on, obtained by Dr. Percy Kendall on the Gambia.

The material available not being, in our opinion, sufficient for the preparation of a correct figure of the Derbian Eland, we have thought it best, as our illustration of this Antelope, to copy, on a reduced scale (Plate C.), the original figures of the Derbian Eland drawn by Waterhouse Hawkins for plate XXV. of the ‘Gleanings.’

We admit, however, that these are by no means satisfactory, for the head and legs of the specimens from which the figures were taken are absent, and the details as to these parts in the figures were probably filled up from conjecture. Wolf’s figure of the head of Reade’s specimen in the ‘Proceedings’ is, no doubt, more accurate, but in this example the legs are likewise deficient.
