About the same time Salt’s Dik-dik was figured by Lichtenstein from specimens in the Berlin Museum obtained by Hemprich and Ehrenberg near Massowah, under the name _Antilope saltiana_. But these celebrated travellers, when they came to treat of it again in their ‘Symbolæ Physicæ,’ although they used the name _Antilope saltiana_ on their plate, proposed in their letterpress to change it to that of _Antilope hemprichiana_ (of Ehrenberg’s MS.), alleging that the original _Antilope saltiana_ of Blainville must have referred to some different species. These authors tell us that Hemprich obtained his first specimens of this species in the month of May, in the woods of the Gedam Mountains, and others in the month of July, near Ilet. They describe it as very common in these localities, but not gregarious. A gravid female was obtained at the beginning of May. Mr. W. T. Blanford, when accompanying the Abyssinian Expedition of 1867–68, met with numerous examples of this Antelope, of which he gives us the following account:-- “The ‘_Beni Israel_’ or ‘_Om-dig-dig_,’ one of the smallest Antelopes known, abounds on the shores of the Red Sea and throughout the tropical and sub-tropical regions of Abyssinia. It is occasionally, but rarely, found at higher elevations; I heard of instances of its being shot both at Senafé and Dildi; but it is not often seen above about 6000 feet. It inhabits bushes, keeping much to heavy jungle on the banks of watercourses, and is usually single, or in pairs, either a male and female or a female and young being found together; less often the female is accompanied by two younger ones, which remain with her until full-grown. “Like _Gazella dorcas_ and many larger Antelopes, the Beni Israel has the habit of depositing its dung frequently on the same spot, so that its usual haunts may be known by little piles of its droppings. It rarely leaves the shelter of the bushes during the day, and is, I suspect, somewhat nocturnal in its habits, as I have seen it feeding on leaves at the edges of the jungle in the dusk of evening. “All the specimens of Salt’s Antelope seen in the Anseba valley differed from those of the coast and of the pass between Komayli and Senafé in their much more rufous colour. There is no distinction, so far as I can see, in size or shape. I am inclined to look upon this as an unimportant variation, the more so that, as previously noticed when speaking of the _Hyraces_, many animals, and especially mammals, have a tendency at times or in particular localities to assume a rufous phase; so that the difference between rufous and grey, or rufous and brown, is one of the least characteristic and certain of specific distinctions.”
