HORSES provide H. excavatum at EL Obeid and R. s. simus 

 at Talodi. ~ ~ ~ 



MULES at Talodi yield R. e. evert si . 



CATTLE populations and movemsnts are comparable to those of 

 DarfvjT. Herds at El Obeid and northwards are infested by B. 

 decoloratus, H. dromedarii , H. excavatum , H. marginatum , hT 

 rufipes , and ^. s. sanguineus . B. decoloratus is probably 

 chiefly transported this far norTh. In the south herds are 

 parasitized by A. variegatixm , B. annulatus, B. decoloratus , 

 H. impressum , rfT rufipes , H. truncatum , and "K, s. simus T A

BLUE NILE PROVINCE* 



The chief tick species and a few of the more uncommon ones 

 are known from this Province but collections have been sparse,

 Medani, the acacia short grass scrub southwards that becomes 



*Most Blue Nile data were supplied by Sudan Government veterina- 

 rians and by the writer *s collections from Wad Medani. Specimens 

 from wild animals are from Sudan Government collections, Mr. D. J.
