(a! 
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 Riippell, who transmitted many specimens to the Sencken- 
bergian Museum at Frankfort-on-the-Main. These were correctly described 
and figured by Cretzschmar in his Atlas to Riippell’s ‘ Travels,’ published in 
1826. Riippell 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.” 
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 ‘Symbole Physice,’ although 
they used the name Antilope saltiana on their plate, proposed in their letter- 
press 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. 
“Tike Gazella dorcas and many larger Antelopes, the Beni Israel has the
