the tick is Kingwilliamstown. There is a city of this name in 

 Cape Province, South Africa but, so far as known, none in Aus- 

 tralia. The specimen came from the Rothschild collection, a 

 frequent source of Soiith African material for Nuttall in the 

 early 1900s. With little hesitation, therefore, this may be 

 considered to be a South African record. Fielding (1926) re- 

 corded I. vespertilionis from North (Queensland bats, but this 

 appears~to be merely a repetition of the earlier literature 

 statement. Taylor and Murray (194-6, p. 41) state that this spe- 

 cies is "doubtfully Australian" and the "original specimen is 

 xmfortunately lost". 



HOSTS 



All authors list bats except for the probably adventitious 

 Hungarian record from a domestic dog (Kotlan 1921A,B). Immature 

 stages and females are usually found on bats; males only in caves 

 inhabited by bats. 



The host of only one of the few specimens originating in 

 Africa has been reported. Nuttall's (I9l6) Algerian specimen 

 came from Pipistrellus (a Vespertilio ) kuhlii . The host number 

 of the specimen collected in Torit was inadvertently not inclided 

 in the vial. The nymphs taken in Kenya (HH) were found, together 

 with the holotype female of Ixodes simplex af ricanus , on Miniop - 

 terus natalensis arenarius . So far as known, there are no other 

 records of both I. vespertilionis and I, simplex subspp. from a 

 single collection. Myotis tricolor of~South Africa has been dis- 

 cussed in the NOTE above. Hipposideros caffer is also a host in 

 South Africa (Arthur 1956A). 



Genera of European bats reported by Neumann (l9l6) are Rhino - 

 lophus , Plecotus, Pipistrellus , and Myotis . The most commonly 

 listed hosts are R. ferrum-eqviinum and R. hipposideros ; the former 

 species is also tlie host of the Japanese specimen reported by 

 Kohls (correspondence). A few other Rhinolophus species are also 

 mentioned by various authors.
