 lands in the dry season but not to the Bahr EL Arab toich. These 

 animals transport goods throughout northern and central Sudan. 

 They are infested chiefly by H. rufipes , possibly the nost common 

 tick of Darfur, and frequently by smaller numbers of H. dromedarii , 

 H. in^aeltatum , H. in^ressvan , and H. truncatum . 0. savignyi also 

 occurs and R. sT simus is pre3ent~in a single collection. Few 

 specimens oT rf7 dromedarii from camels are inclvided but most col- 

 lections from'Darfxir cattle include several specimens of this 

 tick.

 rufipes . Most collections also contain rfT dromedarii , H. " 

 impressum , and H. truncatum and several include H. ing)eTtatum , 

 R. s. sanguinevis , and R.J. simus . 0. savignyi "Has also been

 toich during the dry season and grazing up to 13°N. during the 

 rains. 



Herds in each of the areas represented are most heavily par- 

 asitized by H. rufipes , the total number of specimens of which 

 equal those of a1 1 other species. Also common but fewer in num- 

 bers are H. dromedarii , H. t rune at vim , H. impressum , and H. inroeL .
