The Wild Ass is found in some of the Eastern deserts; while Zebras (probably Grant’s Zebra) just extend into Sudan territory north of Gondokoro on both banks of the Bahr El Jebel.
Buffalo—the shorter-horned northern form (Bos caffer equinoctialis) are numerous in suitable localities, and appear to be holding their own; their distribution is roughly the same as that given for the Elephant.
Of Hartebeests, Bubalis tora is common on the Setit, the Upper Atbara and the Blue Nile tributaries; Bubalis jacksoni takes its place on the White Nile, Bahr-el-Ghazal and in S.W. Kordofan; a much scarcer and more local species, apparently Bubas Neumanni has been found on the White Nile near J. Ahmed Agha. The Tiang[233] or Bastard Hartebeest (Damaliscus tiang) is abundant in the Gezira, and in the southern and western parts of the Sudan; on the eastern side of the country it does not range north of the Dinder.
The Water-buck (Cobus defassa) is generally distributed where water and grazing are to be found; the beautiful Mrs. Gray’s Water-buck (C. maria)—the males of which are marked with a snow-white patch on the withers—is one of the most local of African Antelopes, inhabiting only the swamps of the Bahr-el-Ghazal and Bahr-el-Jebel.
The White-eared Cob (C. leucotis), commencing near Renk, follows the White Nile upwards, increasing in abundance in the Bahr-el-Ghazal, occurring also on the Sobat and the Pibor, and extending along the Bahr-el-Jebel into Uganda. On this last river the Uganda Cob (C. thomasi) has been shot.
The Roan Antelope (Hippotragus equinus bakeri) is locally distributed from the Setit to the south-west of the Sudan; the Blue Nile tributaries are perhaps the chief stronghold of this noble beast.
The Oryx leucoryx is plentiful in Western Kordofan; the Oryx beisa occurs in one or two localities east of the Atbara. The Addax ranges into the deserts of the Western Sudan, but very few have yet been shot by any European.
The greater Kudu (Strepsiceros capensis) is one of the scarcer Antelopes in the Sudan, occurring locally in Kordofan, and from the Blue Nile to the neighbourhood of Suakin.
The largest known form of Eland (the Taurotragus oryx gigas of Von Heuglin) is found in the Bahr-el-Ghazal Province.
The Lesser Reedbuck (Cervicapra bohor) occurs on both the Blue and White Niles and their tributaries, the Blue Nile examples carrying the finest heads. The Bushbuck of the White Nile is Tragelaphus scriptus, the Blue Nile form being T. decula.
