Among the numerous Antelopes procured from the Gambia for the Derby Menagerie by Lord Derby’s agent Whitfield were several examples of this species. Dr. Gray, in the letterpress to the ‘Gleanings,’ tells us that at the time of his writing (April 1850) there was a fine male of _Gazella dama_ living at Knowsley, and that a female, procured by the same collector, which died on its passage home, was preserved in the British Museum. This specimen, a skin of an immature animal, is still in the Museum, to which it was presented by the Earl of Derby, and, strange to say, is still the only example of this Antelope in the National Collection. In 1865 a pair of this Gazelle (as recorded in the Society’s ‘Proceedings,’ 1865, p. 675) were acquired by the Zoological Society of London, from the Zoological Gardens, Antwerp. About the same period Sclater recollects having seen other examples of this Antelope in the Antwerp Gardens, but does not remember to have noticed them in any other of the continental Gardens which he has visited from time to time for many years. In some MS. notes on the Antelopes of the Gambia which Sir Robert Llewelyn, K.C.M.G., the Governor of the Colony, has kindly sent to Sclater, “the Springbuck,” or “Kongko-tong” of the Mandingos, is stated to be “common all over the south bank of the river.” This “Springbuck” can be hardly any other Antelope than the present species. If such is the case, it is remarkable that a beautiful animal, so abundant in a British Colony a few days’ steam from our shores, should be still so little known in our Museums and Menageries. _September,_ 1898.
