Similar to O. scoparia in most respects, but the tail shorter, less bushy, and 
almost wholly of the colour of the back, the terminal black tuft being reduced 
to a few darker hairs at the extreme tip; there are also a considerable 
number of white hairs along each side of it below. Auricular gland large, 
quite naked. 
Skull dimensions ( ¢ ):—Basal length 5°65 inches, greatest breadth 2°95, 
muzzle to orbit 3°44. 
Hab. Abyssinia and Bongoland. 
As already pointed out, the Abyssinian representative of this group differs 
slightly in structure from the forms of the Oribi of which we have previously 
spoken. Its specific name would also indicate that it is an inhabitant of a 
higher district, although Riippell tells us that when he sent the original 
specimen from Senaar in 1825 he had given it in his Manuscript “a far 
more appropriate” one. Be that as it may, Cretzschmar, who undertook the 
description of the vertebrates transmitted by Ritppell to the Museum 
Senckenbergianum before the return home of the latter, chose to call it 
“montana,” and this term cannot now, of course, be altered. 
The original specimen of Ourebia montana was obtained by Rippell’s col- 
lector Hey (after whom Hey’s Partridge, Ammoperdix heyi, was subsequently 
named by Temminck) on the hills of Fazogloa on the Blue Nile in 1823. 
Riippell afterwards found many individuals of it on the high plains of 
Woggera in the neighbourhood of Gondar and in the valleys of the Kulla, 
where they resort to the grassy ravines and thorny jungles. He remarks 
that only the male carries horns, but that both sexes have a pair of inguinal 
glands, the openings of which are concealed by long tufts of white hair. 
The female has four teats. He also remarks that (as he communicated to 
the Zoological Society of London, of which Riippell was a Foreign Member, 
in 1836) the young males of this Antelope occasionally possess the germs 
of a pair of canine teeth, which are lost in the adult stage. This anomaly, 
however, has also been noticed in other Ruminants. 
Theodor von Heuglin met with this Antelope in several districts of Central 
and West Abyssinia at elevations of from 6000 to 8000 feet above the sea- 
level. He remarks that it prefers the rocky and bushy parts of the steppes, 
and often cries out like a Roebuck when struck by a shot. Dr. W. T. 
Blanford, F.R.S., found this Antelope rare in the country traversed by the
