One of the chief ornaments of the Mammal-Gallery in the British Museum is the mounted pair of Livingstone’s Elands obtained by Mr. F. C. Selous in Mashonaland in 1883. The male (as Mr. Selous informs us) was shot near Sadza’s Kraal, west of Marandalla’s, a station on the main road from Salisbury to Umtali, in July of that year, and the female near Salisbury in the following October. The male stands 67¾ inches high at the withers, and carries a pair of horns 22½ inches in length in a straight line; the female is 57½ inches in height, and has horns 27 inches in length. In both these animals the lateral stripes are well defined, and there are no black patches above the knee on the fore leg of the male, though in the female the patches are slightly visible. These specimens are fair representatives of _Taurotragus oryx livingstonii_, and have been figured as such in our illustration (Plate XCIX.), prepared by Smit. But it is right to add that it appears that the skins have apparently shrunk slightly in drying, as in his measurements of the male specimen in question, lately given in the ‘Great and Small Game of Africa’ (p. 426), Mr. Selous states that the height of this animal, “taken on the naked carcase after the skin had been removed,” was 69 inches. Moreover, in former days there were probably still larger specimens, as such reliable authorities as Barrow and Harris agree in stating that the old male Elands were known to attain a height of 6½ feet at the withers. There are also in the National Collection other skins and skulls of the Eland obtained by Mr. Selous, and a number of other specimens, amongst which we may specify a skull and horns of a female from Nyasaland, presented by Sir Harry Johnston, and a skull and horns from the district of Kilimanjaro, presented by Mr. F. J. Jackson in 1892. We may remark that examples of the Eland of the White Nile (the problematical _T. o. gigas_) are much wanted to complete the series in the National Collection, besides which specimens from other definite localities in Eastern Africa and Angola would be very acceptable. _April_, 1900.
