These notes contain the general results of my observations on 
the Natural History of the region traversed by the Anglo-German 
Boundary Commission in the years 1902-4. Memoirs dealing 
more exactly with the collections that were made have already 
appeared in the ‘ Proceedings’ of the Zoological Society (P.Z.8. 
1904, vol. i. pp. 371, 459) and ‘ The Ibis’ (1905, p. 199.). 
MAMMALS. 
Beginning with the larger mammals in the country under 
discussion, it may be stated that Elephants appear periodically in 
the swamps and forest near the mouth of the Kagera River on 
the northern side. These elephants stray in this direction, 
probably, at a time when it is dry in the interior. They come, 
no doubt, from the herds in northern Ankole and Toru. At no 
other point were traces of elephants seen except one single track 
going from north to south from the Koki hills towards the 
Busenya forest. In the west, a few elephants were noticed near 
the shores of Lake Albert Edward, also probably stragglers from 
the herds further north. There was no evidence of elephants 
crossing from south to north, or vice versd, along the Ist parallel 
south latitude. 
it may perhaps be assumed that the herds of elephants reported 
by H. 8. Grogan and other travellers in the Mfumbiro district 
belong to the forest-regions of the west. ‘The herds of elephants 
on the east of Lake Albert Edward and Ruwenzori probably do 
not wander into the Congo forests. It has been noticed that the 
elephants to the west of the great line indicated by Lake 
Tanganyika, Lake: Kivu, Lake Albert Edward, Lake Albert, &c., 
and the Nile differ in many particulars from those lying to the 
east of this line. At the same time, it must be remembered that 
large herds of elephants are in the habit of crossing the Nile to
