We are not aware that examples of Thomson’s Gazelle have ever been brought to Europe alive; but it would appear that young individuals of this species are often captured and kept in confinement in British East Africa. The late Capt. B. L. Sclater, R.E., who made the road from Kibwesi to Port Victoria in 1895–97, in his letters written home refers to several such cases, and Lieut. G. E. Smith, R.E., who was second in command of Capt. Sclater’s party, kindly sends us the following notes about them:--“Early in January 1896 Capt. Sclater obtained from the Masai two young Thomson’s Gazelles, which were fed by hand and throve well. They became quite tame and used to run about the camp and play with a puppy. One of them subsequently ran away, but the other remained with the camping-party for nearly a year.” At Kikuyu, Lieut. G. E. Smith saw a pair of Thomson’s Gazelles then fully grown, having been in possession of Mr. Hall, the Resident, for more than two years. The buck was rather fierce and apt to attack natives with his horns. Major Eric Smith, we are told, also generally had two or three of these Gazelles scampering about his station at Naivasha very tame. Our figure of the male of this Antelope (Plate LXVIII.) has been prepared by Mr. Smit from a mounted specimen in the British Museum presented by Mr. F. J. Jackson. There are also in the Museum a second mounted specimen of a male presented by Mr. H. C. V. Hunter and the skull of a male from Lake Naivasha presented by Col. Lugard. Besides these the Museum contains two frontlets with horns, being the typical specimens obtained by Thomson, and some skins and skulls of both sexes from Machakos, presented by Mr. S. L. Hinde, as already mentioned in his letter. _May,_ 1898. [Illustration: THE BOOK OF ANTELOPES, PL LXIX _Wolf del J Smit lith_ _Hanhart imp_ Grant’s Gazelle. GAZELLA GRANTI. _Published by R. H.
