“I have shot large numbers of Gazelles for food at various times, and have always noticed that the plateau variety has a much thicker and longer coat than the other. This is possibly the result of natural selection, as the high plains of the Ogo and the Haud, where it lives, are subject to sweeping cold winds, and the nights are very cold indeed. The altitude of these plains inhabited by the Plateau Gazelle is from three thousand to over six thousand feet, but doubtless they go much lower towards Ogádén. The great steppe of Gólis, with its prolongations east and west, which rises some forty miles inland, and separates Guban, the low coast country, from Ogo, the high interior country, forms the natural line of demarcation between these two Gazelles.” [Illustration: Fig. 63. Head of adult female Speke’s Gazelle. (Mr. F. Gillett, F.Z.S.)] A still more recent explorer of Somaliland, Mr. A. E. Pease, M.P., F.Z.S., has most kindly favoured us with some excellent notes on Speke’s Gazelle and its sister species, which we cannot do better than reproduce. Mr. Pease has also sent us along with his MS. remarks a sketch-map of the northern part of Somaliland, in which the ranges of these two species are accurately shown. He writes as follows:-- “Speke’s Gazelle is called ‘Dhero’ by the Somalis, who do not distinguish it by name from _Gazella pelzelni_. It is a ‘Dhero,’ just as the other, and yet there is no Somali shikari or any other observer who cannot discriminate at a glance between these two very distinct species--distinct in colour, size, horns, and habitat, whilst the peculiar nose, covered with soft pliable folds of loose skin, of the _G. spekei_ is alone sufficient to mark it as a species apart. “The Speke’s or Plateau Gazelle has been termed the Mountain Gazelle by some writers; but it is not strictly a mountain Gazelle, but one that frequents the higher plains and low foot-hills north and south of the Golis. But with its distribution I will deal later.
