H. tiiranic\3m , is considered by South African and French work- 

 ers as a subspecies of H. rufipes and by Russian workers sis a sub- 

 species of H. marginatiim ^a H. plumbeum of Pomerantzev). 



The specific entity of H. glabrum has been de:x)nstrated in 

 laboratory rearings by Theiler, who has kindly provided material 

 for the present study and has provided a manuscript (Theiler 1956) 

 on distribution and ecology in South Africa for use herein in ad- 

 vance of her own publication. 



H. ttiranicum (■ H. glabrum ) appears to have been introduced 

 into the arid South ilJrican Karroo on Persian sheep. It is un- 

 known elsewhere in Africa. Persian sheep were originally intro- 

 duced into South Africa in 1872, having been purchased from a 

 ship from the Mediterranean then anchored in Table Bay (Lounsbury 

 190/JE). Subsequently others were iii^xtrted from Aden. The exact 

 locality from whence any of these importations originated does 

 not appear definitely to be known. A number of flocks were scat- 

 tered about South Africa at the time (190A) Lounsbury reported 

 their high degree of immunity to heartwater. 



H. rxafipes glabnim was briefly described by Delpy (19/+9A) 

 from material reared from females from Karroo sheep sent to him 

 by Theiler. The source of this material has been identified in 

 correspondence with Dr. Delpy and Dr. Theiler; it is not found 

 in the literature. Subsequently, Delpy (19490,1952) indicated 

 that H. rufipes glabrum is a poorly known, two host tick, that 

 it also occurs in Iran, and that it is not of considerable im- 

 portance in the transmission of bovine theileriasis, Theileria 

 annulata. This species occurs in southern Russia (Pomerantzev
