N. Rhodesia and Katanga District of Congoland. 79 
portions of North-east Rhodesia. I have already recorded 
the birds collected on the first Expedition in a paper pub¬ 
lished in the ‘ Memoirs and Proceedings of the Manchester 
Literary and Philosophical Society ’ (vol. 51, pt. iii.). The 
majority of the species of the first collection, even when not 
represented by skins, are now again mentioned with addi¬ 
tional notes as to their distribution and habits. There are 
also a few species, mostly of large size, which were observed 
hut of which skins were not brought home. 
I have already described the general features of the 
country traversed and have pointed out * the marked in¬ 
fluence which the great Mchinga Escarpment, west of the 
Luangwa Valley, has upon the distribution of the local fauna. 
Very many of the birds in the Luangwa Valley at the foot 
of the Escarpment are characteristically South African, 
whilst Central-African birds appear immediately the top of 
the Plateau is reached, with, especially in Katanga, an 
admixture of species belonging to the tropical West Coast. 
Apart from special localities, such as Lake Bangweolo which 
swarms with water-birds, the open plains which are tenanted 
by many species of Larks and Longclaws, and the patches 
of dense forest which are full of Ground-Thrushes, Bulbuls, 
and forest-loving Flycatchers. The most interesting bird-life 
is, perhaps, to be found in the rather thin woodland which 
covers a very large proportion of the country. 
It is in this woodland that, as Marshall and other observers 
have pointed out, large parties made up of many species of 
insectivorous birds are met with. These birds are usually to 
be found travelling slowly in a definite direction, searching 
the trees and bushes for insects as they go along. An actual 
party of this nature observed near Kambove on March 29th, 
1907, comprised examples of the following birds:— Irrisor 
viridis (4 or 5), Rhinopomastus cyanomelas schalowi (1), 
Thamnolcea shelleyi (2 pairs), Tchitrea plumbeiceps (1 pair), 
Bat is molitor (several), Dendropicus hartlaubi (1 pair), Sal- 
pornis salvadorii (1), Parus afer (1), Parus rufiventris (1), 
and several specimens of Eremomela and other Tree-Warblers, 
* In a paper read before the Royal Geographical Society (Nov. 22nd, 
1909).
