GAME ANIMALS OF JUBALAND

animals are in good condition and it is more fully developed 
in the males than in the females. What purpose it may serve, 
I am unable to say. 
Writers on the game of East Africa have stated that the 
arrola is found on ‘ the plains bordering the Tana ’ or merely 
in great numbers in Southern Somaliland (! !) This is very 
misleading, and I took especial pains to discover the limits of 
its range. I have come to the conclusion that they are not 
found west of longitude 40° E. or north of latitude 0° 35' S. 
They do not inhabit the country south of the Tana nor the 
district immediately adjacent to the coast. The Somali apply 
the word ‘ arrola ’ to the impalla as well, and this has led to 
the report that Hunter’s antelope is to be found in the 
Lorian district. This report I cannot credit, as the country 
near the swamp is unsuitable to their habits, and I saw no 
trace of any kind while I was there to lead me to believe they 
were to be found in that district. 
Of greater interest, perhaps, to the naturalist than to the 
big game hunter is the race of Grant’s gazelle, inhabiting the 
coastal region of Jubaland north of the Aruoleh Biver. In 
‘ The Game Animals of Africa,’ by Mr. B. Lydekker, F.B.S., 
it is stated, on the authority of Mr. 0. Neumann, that Grant’s 
gazelle is not found within 150 miles of the sea, its place there 
being taken by the closely allied form, Peter’s gazelle. The 
latter animal was originally described in 1884 as a distinct 
species, but it is now generally regarded merely as a race of 
Grant’s gazelle. Moreover, it was commonly believed that 
Petersi gazelles were to be found all along the coast north 
as well as south of the Tana. On investigation this, however, 
proved to be quite an erroneous idea, and my own experience 
leads me to believe that Petersi gazelles are not found anywhere 
north of the Tana, and in this Mr. A. B. Percival agrees with 
me. Their place along the coast between the Tana and the 
Juba rivers is taken by a closely allied race, almost perfectly 
intermediate in form between G. G. Brighti and G. ( Granti ) 
Petersi. 
It differs from the former in its smaller bodily size, the 
paler tint of its body colour, and in its shorter and straighter 
horns, while the white area of the rump patch intrudes even
