Our countryman Henry Salt, F.R.S., who travelled into the interior of Abyssinia at the beginning of the present century, and obtained many objects of Natural History, was the original discoverer of this species, which appropriately bears his name. It will be found mentioned in the fourth Appendix to his ‘Voyage in Abyssinia’ under the name “_Madoqua_” by which he says it is called in Tigré. Salt’s specimen in the Museum of the Royal College of Surgeons attracted the notice of M. de Blainville when he came to London in 1815 to collect materials for his articles on Mammals, and upon them was based the name _Antilope saltiana_, by which de Blainville afterwards described them before the Société Philomatique of Paris. The next observer that seems to have met with this Antelope was the German naturalist Rüppell, who transmitted many specimens to the Senckenbergian Museum at Frankfort-on-the-Main. These were correctly described and figured by Cretzschmar in his Atlas to Rüppell’s ‘Travels,’ published in 1826. Rüppell met with this species in great numbers on the eastern flanks of the Abyssinian coast-range, where, he says, it is known by the natives as the “Atro.” “It is found amongst the low brush-wood, and is fleet and wary in escaping from its numerous enemies.”
