Skull with short broad nasals, the premaxillæ not or barely touching their outer corners. Basal length in an old male 6·5 inches, greatest breadth 3·35, muzzle to orbit 3·6.
Horns but slightly divergent, evenly and strongly curved backwards for three-fourths their length, their tips gently recurved upwards.
Female. Like the male, but the horns slender, little ridged, less curved, about three-fourths the length of those of the male.
Hab. Interior Plateau of Somaliland.
There can be no doubt that the two Gazelles which inhabit the maritime plain and the high inland plateau of Somaliland respectively, although they are closely allied, and have been confused together by some writers, belong to distinct species, distinguishable by well-marked characters. The Gazelle of the interior plateau, which we treat of first, when compared with that of the coast-land is at once recognizable by the generally browner colour, the darker lateral band, the black nose-spot, and above all by the wrinkled and elevated nose of the adult, which is not met with in the sister species.
Speke’s Gazelle was first discovered by the energetic African explorer, whose name it appropriately bears, during his expedition to Harar in the summer of 1854 in company with the late Capt. Sir Richard Burton[10]. Speke, who attended to the natural history of the expedition, forwarded the collections made upon this occasion to Blyth, at that time curator of the Asiatic Society’s Museum at Calcutta, and in the zenith of his zoological work. In his report upon the collection, which was published in the twenty-fourth volume of the ‘Journal of the Asiatic Society of Bengal,’ Blyth did not venture to bestow a new name on this Gazelle, although he gave an accurate description of it, and added a note (obtained from Burton) calling special attention to “the elevation of loose replicated skin upon the nose,” so that there can be no doubt as to which of the two allied species Speke’s specimens (which are still in the Calcutta Museum[11]) belong.
In the reprint of Blyth’s ‘Report,’ which was edited by Speke in 1860 after his return to this country, this Gazelle was erroneously referred to G. cuvieri of Ogilby. In 1883, however, Blyth, who had discovered that this was a mistake, proposed the name Gazella spekei for this species in his ‘Catalogue of the Mammals of the Asiatic Society’s Museum,’ and this appellation has been generally adopted for it ever since.
When the late Sir Victor Brooke wrote his Monograph of the Gazelles in 1873 Speke’s Gazelle was hardly known in this country, and Brooke was only acquainted with it from photographs of the type specimens in the Calcutta Museum. But since that date Somaliland has been fully opened to British travellers, and the numerous explorers and sportsmen who have visited that much-hunted country have brought back good sets of specimens both of Speke’s and of Pelzeln’s Gazelle, and made us well acquainted with the ranges and other peculiarities of these two species.
One of the first British travellers who visited Somaliland, and made the acquaintance of Speke’s Gazelle, was the late Mr. F. L. James, who proceeded there on a shooting-expedition in January 1884, accompanied by his brother and Mr. E. Lort Phillips[12]. Mr. Lort Phillips read some notes on the Antelopes obtained on this occasion before the Zoological Society in December 1885, and in alluding to this Gazelle called it the “Flabby-nosed Gazelle,” to which term Sclater attached a footnote stating that it was “probably of a new species,” but required further examination. This examination Sclater bestowed upon Mr. Lort Phillips’s specimens shortly afterwards (see P. Z. S. 1886, p. 504), and came to the correct conclusion that the so-called Flabby-nosed Gazelle was quite distinct from the species of the coast land. He unfortunately did not perceive that it was the species of the high plateau and not that of the coast land, which had already been named Gazella spekei by Blyth, and therefore gave it a new name, Gazella naso, under which appellation it will be found described and its characteristic head figured in Sclater’s article in the Zoological Society’s ‘Proceedings’ for 1886. But, as Thomas has subsequently shown (P. Z. S. 1891, p. 210), there can be no doubt that Gazella naso is merely a synonym of Gazella spekei.
Another well-known author, who must not fail to be quoted in any reference to the game animals of Somaliland, is Capt. H. G. C. Swayne, R.E. Capt. Swayne has made no less than seventeen trips to that attractive country, and is probably better acquainted with its larger mammals than any other living individual. In his excellent narrative of his adventures[13], Capt. Swayne has given us some capital notes on Speke’s Gazelle and its near ally Pelzeln’s Gazelle, both of which are known to the natives by the same name “Dhero.”
