GAZELLA TILONUEA. 
351 
“ Travelling up from Berber to Kassala, md Atbara, the Isabella Gazelle alone 
is seen until within a half»day’s march of Adurrama. From this point this species 
and Ariels {G. soemmerringi) are both seen in great numbers. G. tilonura may 
be found south of Gog-regeb, but only very few, while G. isabella becomes less 
numerous, and the Ariels perhaps more so. From Asobri southwards on the Atbara, 
Heuglin’s Gazelle becomes much more common than G. isabella, the latter being 
distinctly rare south of Kashm-el-Girba. At Kassala and up the Gash Fiver, Heuglin’s 
is much more common than the Isabella Gazelle, though both are found. There was a 
herd of G. isabella that lived near the Jebel at Kassala, and was to be found any day 
by riding close in round the base of the mountain, but Heuglin’s were much 
more common. 
“ Heuglin’s Gazelles are also found from Gedaref up to Gallabat, but no Isabellas 
(at least I have never seen any of the latter). There is another, larger, black-striped 
Gazelle at Gelet Arang Hills.”

Very little is known about the animals of this district, and specimens with accurate 
locality are much needed in the British Museum. It appears from the above note that
