RESEARCH IN BRITISH WEST AFRICA. 321 
At Bokani the only blood-sucking flies seen during my visit in October were 
G. tachinoides and Haematopota lacessens, but Rhipicephalus simus and Clenoce- 
phalus canis were very abundant on dogs. G. tachinoides was also obtained at 
Gudu Gudu. Dr. J. W. Archibald, who was stationed at Bokani and afterwards 
at Jebba, sent in a number of species, but as the only data accompanying them 
were “Jebba and Bokani 1910” it is impossible to determine the precise locality 
of each. It may be advisable, however, to enumerate them here :—Myzomyzu 
Sunesta, M. costalis, Mansonioides uniformis, Glossina palpalis, G. tachinoides, 
G, submorsitans, Tabanus biquttatus croceus, T. fasciatus, T. latipes, T. ditaeniatus, 
LT. par, Tabanus sp. nov. and Hippobosca maculata. 
(7.) Zungeru and its Environs. 
The town of Zungeru (locally known as the cantonment) is situated on the 
right bank of the River Kaduna, and is the seat of administration of Northern 
Nigeria. I do not propose to enter into a lengthy description of this town, but 
shall draw attention to only a few of the most important points in connection 
with the blood-sucking insects which occur there, and the possible causes of their 
existence and abundance. It might be well, therefore, to enumerate these at 
this stage.
