/ "Giraffe ; Inasmuch as adiilts commonly parasitize so many 

 large game animals, infestation of giraffes is to be anticipated. 

 However, no published records have been found indicating that this 

 is so. In Bahr EL Ghazal Province, vhere this is a common tick 

 and where numerous giraffes were examined, R. s. simus was not 

 found on these animals .7 "" ~ 



Exceptional hosts ; Hedgehogs (Howard 1908, Van Saceghem 

 19U, Bedford 1932B;. Hares (Loveridge 1923A, Bedford 1932B, 

 Lewis 1932A). In the laboratory, Lewis (1932A) foiond that adiilts 

 feed readily on hares (see also immature stages below). Rabbit 

 (Howard 1908). Cane rats (See also next paragraph. Sudan records 

 include a single collection from Bahr KL Ghazal and the Onderste- 

 poort collection contains three lots from Southern Rhodesia). 

 Rodents (South African Otonys , Aet ho my s , and Rhabdomys ; foiir 

 records: Theiler, correspondence^ . 



?MistaJcen identity ; Specimens from a cane rat (Bedford 1932B) 

 were later found to be R. simpsoni and not R. simus (Bedford 193A). 

 Neumann's (1922), Mettam's ^1932j and Loveridge 's (,1923A) specimens 

 from cane rats should be checked against R. simpsoni . See HOSTS 

 of R. simpsoni , page ~ 



"Large gray cattle tick ( ?Rhipicephalus sinus Koch) (sic) 

 attached to and completely blocking up the ear opening" of a 

 lizard, Mabuia striata (Loveridge 1923D). This sounds like an 

 Aponomma tick. 



Note 



Adults, found frequently in rodent nests in which the immature 

 stages feed, are always newly molted, unmated, unfed individuals 

 biding their time before ventiu-ing forth to find a host more at- 

 tractive to them than rodents. 



Larval and Nymphal Hosts 



Rodent hosts ; All of the numerous records of adults in the 

 Onderstepoort collection are from larger size animals and most 

 records of immature stages are from small, nest- inhabiting mammals 

 (Theiler, correspondence). Our field experience in East Africa
