As regards the exact range of the Oribi in Mashonaland, Mr. F. C. Selous, in his ‘Hunter’s Wanderings,’ gives us the following particulars:--“North of the Limpopo, this Antelope is only to be met with in the following districts, viz. in north-eastern Mashunaland from the river Umzweswe to beyond the river Hanyana, in the open valleys which occur between the forest belts near the watershed, but to the north of the Machabe hills; on the exposed open downs nearer the watershed, and lying between the Machabe hills and Intaba Insimbi, I never saw any. On a large flat about fifty miles to the south of the junction of the Umfule and Umniati rivers, I saw a good many Oribi in 1880. Except in this district of the Mashuna country, the only other place south of the Zambesi where this Antelope exists is in the valley of Gazuma, an open boggy flat of only a few hundred acres in extent, which is situated at about thirty miles to the south-west of the Victoria Falls. Then again a few are to be seen on the northern bank of the Chobe, on the open ground bordering the marsh, in the neighbourhood of Linyanti. One never sees more than two or three of these Antelopes together. The horns of the male attain to a length of about 5 inches, and are ringed at the base.” There is a mounted pair of this species in the gallery of the British Museum which formerly belonged to the old “South-African Museum” of Sir Andrew Smith, besides some skins and skulls from the Cape without exact particulars. There is also the skull of an adult male from the Umfili River, Mashonaland, obtained by Mr. F. C. Selous, in the same Collection. We are not aware that the Oribi has been kept in captivity in the Cape Colony, or ever brought alive to Europe. _December, 1895._ 42. PETERS’S ORIBI.
