came from Spilotes _£» pullatus (= variabilis ) . Tuff adders , Bitis 

 spp., have been reported by Hirst (1909^, Robinson (1926), Love- 

 ridge (1928), Bequaert (1930A), and Hoogstraal (195AC); Miss Walker's 

 Tanganyika collection (correspondence) contains four males and a 

 female from one puff adder. Python sp. has been listed by Neumann 

 (1911) and Lewis (193A). 



Mammals, other than the rhinoceros, are also occasional hosts. 

 Theiler's unpublished records include some advilts from domestic 

 cattle and sheep. Lewis (1939A) found specimens rarely on buffalo 

 sind on domestic cattle. Two buffaloes were listed by Bequaert 

 (1930A,1931) and one by Robinson (1926); my collection contains 

 37 specimens from a single buffalo in Kenya. Neumajm (l91l) re- 

 corded a genet, Genetta pardina , Robinson (1926) an eland, and 

 Tonelli-Rondelli (1930A/a bushpig. In my collection are numerous 

 advilts from giraffes in Kenya. Alexander (l93l) was unable to 

 induce adults to feed on domestic animals. 



Among birds, the guineafowl h;-s been recorded as a Uganda 

 host by Mettfim (1932). 



Man was reported as an actual host by Charters (19A6) in 

 Ethiopia. 



Nymphs are sometimes taken with adults from tortoises. Dr. 

 Theiler (unpublished records) has numerous nymphs from fowls. 

 Seven nymphs were removed from the African hoopoe, Upupa africana , 

 in Mozambique (Hoogstraal 195AC). Lounsbiiry (1905*) and Howard 

 (1908) reported that larvae sind nymphs feed readily on lizards, 

 cattle, goats, tortoises, and birds. 



In the Onderstepoort laboratory, larvae and nymphs feed 

 readily on guineapigs but adults do not (Theiler, correspondence). 

 Kenya larvae and nymphs from females from tortoises feed well on 

 the ears of rabbits, and resulting adults on the scrotum of a ram. 

 This is a hardy species, and sixteen-month old nymphs feed quite 

 well while adults remain alive for 23 months without feeding (J. 

 B. Walker, correspondence). See REMARKS below.
