“In 1894 the Touaregs raided as far north as the southern shores—if they can be called shores—of the Chott Djereed. In 1895 we crossed the western end of this Chott, and, so far as we could judge or learn, the Chott was without water in any part; it had been an exceptionally dry year, and the country between the mountains and the Djereed we found absolutely devoid of inhabitants. “At El Oued there was in the fort a tame Addax familiarly called ‘_Begra_,’ and this was the only living specimen we saw during our journey. It was not a very good example, but had rather a fine pair of horns. It had been presented by some Chambas to the Commandant.” From Morocco we have no intelligence of the Addax, although it will be doubtless found there in the desert south of the Atlas. From Senegal, likewise, we have little certain to record except the receipt of living animals of this species on more than one occasion, especially a fine pair now in the Zoological Garden at Antwerp, where Sclater has lately examined them. We do not usually quote Rochebrune’s ‘Faune de la Sénégambie,’ as it is hardly a reliable authority, but we find that he says that the Addax is “common” in Cayor and Oualo on the right bank of the River Senegal, and this river is probably its southern limit on this side of Africa. The Addax is occasionally, but not very frequently, brought to Europe alive. In the twelfth volume of the ‘Nova Acta’ of the Leopoldino-Carolinian Academy (1824) will be found a figure and description by Dr. A. W. Otto of this Antelope, taken from a fresh specimen that had died in a menagerie. Otto described it as belonging to a new species, “_Antilope suturosa_,” but it was manifestly only an Addax in its darker winter coat. In 1827 Geoffroy St.-Hilaire and F. Cuvier published a description of this Antelope in their great work upon Mammals from a male specimen living in the Jardin des Plantes, received from the then Pasha of Egypt. Figures are given of this animal (pls. 388, 389) in both its summer and winter dress, and it is pointed out that in the latter it is the _Antilope suturosa_ of Otto. The Zoological Society of London appear to have first received living examples of the Addax in 1849. In 1861 a fine male was presented to the Society by Sir John Gaspard Le Marchant, then Governor of Malta. In 1864 one was obtained by purchase, and in 1876 another. At the present time there are no examples of the Addax in the London Gardens, but last summer there was, as already stated, a fine pair in the Jardin Zoologique of Antwerp. Our illustration of this animal (Plate LXXXVI.) was put upon the stone by Mr. Smit, some twenty years ago, from a water-colour sketch made for Sir Victor Brooke by Mr. Wolf. It represents an adult animal in summer pelage.
