In a note accompanying the specimen, in which he expresses a sagacious 
doubt as to “its being the same as the South-African animal,” Mr. Jackson 
adds :— Up north all along the top of the Elgeyo Escarpment (continuation 
of Mau) into Turquel to the north and north-east of Mount Elgon it is very 
common, and takes the place of B. cokei. Round Baringo it is fairly 
plentiful, but some marches south of Njemps B. cokei takes its place.” 
Mr. Ernest Gedge, who accompanied Mr. Jackson in his adventurous 
expedition, has kindly furnished us with the following excellent field-notes 
on this Antelope :— 
“« The first specimens of Jackson’s Hartebeest were obtained on the Mau 
plateau in British East Africa. This plateau extends in a northern and 
southerly direction through the Masai country, and varies from 8000 to 
9000 feet in elevation. 
“West of Lake Naivasha the plateau is covered for the most part with 
dense, almost impenetrable forests, but farther north the scenery becomes 
more park-like, the forest clumps being intersected with grassy ranches, 
which open out on to the broad expanse of the Angata Nyuki, the latter 
extending right up to the eastern boundaries of Kavirondo. The whole of 
this district is frequented by B. jacksoni, which is also found north of Lake 
Naivasha in the localities bordering on Lakes Nakuro and Baringo north 
and west of these points ; again, it inhabits the Suk country, Chibchangnani, 
Turquel, Karamojo, and possibly Turkana; whilst farther west it is common 
in the district round Mount Elgon;and is generally met with throughout 
Upper Kayirondo, Usoga, and Uganda, wherever the conditions are 
favourable. 
“‘T have seldom encountered B. jacksoni in large herds, though in habits 
it differs very little from other species of Hartebeest. More frequently it is 
met with in small groups, in twos and threes, or singly. It would appear to 
change its locality to a very great extent according to the seasons. ‘Thus, 
during the dry months of the year it will be found plentifully scattered over 
the highlands, from whence it retreats to the low country at the approach of 
the rains. In illustration of this, I would mention that when on my journey 
to England in 1892, in the month of December, the lowlands at the foot of 
the escarpment were almost entirely deserted, whilst on the high plateau 
above I met with these Antelopes in great numbers. 
On my return journey in the month of July of the following year the
