Contemporary reports of the rhinoceros. Rhinoceros bicornis 

 subspp. as a host are chiefly those of Robinson (.1926J who re- 

 corded half a dozen collections from Kenya, Nyasaland, and Rhode- 

 sia. My collection and that of the Museum of Comparative ZoSlogy 

 contain specimens from rhinoceros in Kenya. I^Iiss Walker's Tajiga- 

 nyika collections (correspondence) contain LH males and seven 

 females from four rhinoceros hosts. The vrhite, or square- lipped, 

 rhinoceros, Ceratotherium s. simum, is a host in Zuliiland (Curson 

 1928).

Recent records from tortoises, Testudo spp, or Kinixys 

 .ana, are those of Neumann (1922 j, Robinson (1926 J with 



numerous collections from throughout the tick's range, and 

 Hoogstraal (195/^) from Sierra Leone, Bedford's (1932B) state- 

 ments and Theiler's unpublished records from South Africa indi- 

 cate that tortoises are commonly infested in Transvaal and are 

 the tick's chief host there. Other scattered records for tor- 

 toises are those of the Sudan specimens above, Mettara (1932) 

 for Uganda, V/ilson (1950B) for Nyasaland, and Santos Dias' (1953B) 

 summary of Mozambique ticks in which no other hosts are listed for 

 A. marmoreiim . A single collection from Tanganyika consists of 

 six males aJid nine females (j. B. Walker, unpublished). 



The warrener or leguan lizard, Varanus spp., is sometimes 

 attacked. More recent reports are the single collection of Ro- 

 binson (1926) and tliat from the Sudan listed above, Mettam's 

 (1932) Uganda note, Loveridge's (1936A) Kenya record, a few lots 

 in the Onderstepoort collection (Theiler, unpublished), arid a 

 few lots in the Iffl collection including one from Angola, 



Some snakes are hosts, apparently only exceptionally^'. 

 Neumann's (1911 ) A, spar sum (said to be a synonj'Tn of A. raarmoreum ) 



*The hosts of A. s. sparsum MeuTnaxm, 1399 (according to Robinson 

 1926 a synonym of A. marmorpum ) were reported hy Neumann to be 

 Spilotes variabilis and Testudo mauritanica from Algeria and East 



S 



rica. _S. variabilis is a synon\-m of S. _£. pull at us , a large 

 South American tree snake (loveridge, correspondence ) . Therefore, 

 since A. mar mo re urn (= A. sparsum ) does not occur in South America, 

 either Neumann's locality record or host record is incorrect. The 

 fact that the "'Algerian'' material of A, sparsum was collected in a 

 EuropeaJi zoological garden (cf . page "^26 J would suggest that both 

 data are difficult to assess. It further suggests that the vali- 

 dity of the synonymy of A. sparsum should be reinvestigated,
