H e considers the two to be decidedly distinct; and one of his two specimens is from the Galla country, the other from the White Nile. In m y collection of drawings I have found a characteristic representation, taken from the living animal, of the cow of Bubalus bra-chyceros, Gray, the great-eared Buffalo of Western Middle Africa. Bubalus brachyceros. This animal was from the Foulah country, north of Sierra Leone, where the species is abundant. It was met with by Capt.
