Grant in Ugogo measured 15 inches round the curve. Comparison with allied Species. Gazella granti belongs, as pointed out in m y former description, to the group of long-limbed large Gazelles which are distinguished by the white of the rump projecting in an angle into the fawn-colour of the back and sides (vide P. Z. S. 1873, p. 537, B'). The allied species are G. scemmerringi, G. mohr, and G. darna. From all these it differs in the very much greater size, and in the form of the horns. It is also peculiar in the presence of the dark lateral band, which is wanting in the three above-named species, and in the remarkably definite black pygal band, which is only shown in very young specimens of Gazella scemmerringi, is absent entirely in Gazella darna, and only indefinitely shown in Gazella mohr. In the watered-silk mottling of the neck and back Gazella granti differs from all other known Gazelles. |
