RESEARCH IN BRITISH WEST AFRICA. Bl 
days were spent in this vicinity, and the return journey was made, by a 
different route, to Kogin Sirikin Pawa (also on the railway), which was reached 
on December 7th—the total distance covered being about ninety-seven miles. 
This part of the country is very imperfectly known, and several of the towns 
mentioned here are not given on any map, but their approximate position may 
be gauged from the text of the report and the route shown on the 
appended map. The first day’s journey brought us to Wuye, a distance 
estimated at about nine miles, but very difficult trekking owing to the 
extremely hilly and rocky nature of the country. The route was very sinuous, 
and numerous streams were crossed. The vegetation as a whole was fairly open, 
but a few dense kurimi-like patches were traversed. No blood-sucking flies, 
however, were seen during the journey. Wuye is a small Gwari town on the 
top of an extremely steep hill, and it is noteworthy that the majority of the 
Gwari towns are so situated for purposes of defence; thus the probability of 
Glossina occurring in them is very remote. At and around this town the following 
species of Tabanids were caught, Haematopota decora, H. pallidipennis and two 
species of Tabanus, both probably new. 
The next town at which we camped was Doka (shown on the map), distant 
about seventeen miles. The first part of the road is very rocky and similar to 
that between Kugo and Wuye, but mostly down-hill. When that part is passed, 
the road is good, and there is abundant low serub and long grass. A tributary 
of the Kogin Sirikin Pawa had to be crossed, and later that river itself. Several 
kurimis were passed through, and, although there is dense vegetation along the banks 
of both the streams mentioned, and all seemed likely haunts for tsetse, none was 
seen; the only blood-sucking flies caught being Haematopota pallidipennis, and 
one specimen of the new Tabanus obtained at Wuye. 
Doka is a Kadara town of moderate size situated on the edge of an extensive 
kurimi. The camp was pitched in a clearing in this kurimi, the vegetation of 
which was so dense that the sun’s rays hardly penetrated and the air was damp 
and musty. Numerous Glossina palpalis occur at all parts of the kurimi and in 
the town itself. 
From Doka to Kateri is roughly about eighteen miles. The country is covered 
with open bush, but this is intersected in every direction, at varying intervals, by 
long stretches of dense bush. In several of these G. palpalis was seen, and 
doubtless oecurs in all. At the River Dinia, which was crossed on this march, 
G. palpalis is also abundant. 
Kateri is a Kadara town situated in a small open clearing in the centre of a 
dense kurimi, which extends for several hundred yards all round, while radiating 
from it are several moderately wide strips of bush of a similar nature (Pl. XIV, 
figs. 1 and 2). The Kadaras are a very primitive and shy people ; the women 
are absolutely devoid of clothing, and the children are supported on their backs 
by skins, chiefly those of a species of monkey and the harnessed antelope. The 
importance of this fact is seen when one remembers that the women are the 
water-carriers, and that the water-pools stand in thick bush swarming with tsetse, 
so that they have no protection from the attacks of these insects. One case of 
sleeping sickness was found in this village, and though there was no evidence of
