fusca, Walk.), " were caught in January, 1902, at Manga- 

 mara, a little way to the north of Dar-es Salam, beyond 

 Msimbasi Creek." 



The following is a translation of the concluding 

 paragraph of this paper (p. 175). 



"Now the most interesting question is whether this 

 species of Glossina also conveys Surra-disease. Reasoning 

 from general conclusions derived from analogy in con- 

 nection with the diseases due to infection of the blood, 

 in which each parasite has its own particular host and 

 intermediate host, I should be inclined a priori to answer 

 this question in the negative. This biting fly is evidently 

 not rare near Dar-es-Salam, and no case of Surrahas yet 

 been observed originating from there. At the place 

 where the flies were caught the same cattle and goats 

 have grazed for a long time, without disease appearing 

 among them. The examination of the blood of the goats 

 has so far not revealed any Trypanosomes, but this 

 examination must be continued and extended to cattle 

 and donkeys. I think, however, it may be assumed that 

 Surra-disease is not conA^eyed by Glossina tahaniformis."
