comnujn in the moimtains of the Yemen in southern Arabia (Sanborn 

 and Hoogstraal 1953; Hoogstraal, ms.)» which is an outlying part 

 of the Ethiopian Faunal Region. It is not known from Madagascar 

 (Hoogstraal 1953E) and I have not seen it in Turkey. 



In Europe, H. leachii has been said to occur in Yugoslavia 

 (Oswald 1938} an3 in Greece (Oswald 1938, Pandazis 19A7} but 

 these records are considered questionable. A German specimen 

 fovmd on a migrant stork from Africa was mentioned by Schulze 

 (1937A). Soviet reccirds (Olenev 1928) refer to different spe- 

 cies and Pomerantzev (1950) does not consider it to be a member 

 of the Russian fauna. 



The exact relationships of Oriental Faunal Region fonns 

 ascribed to this species by Nuttall and Warburton (1915) are 

 at present under study. Apparently most, except the subspecies 

 indie a Warburton, 1910, represent different species. Numerous 

 species, obviously derived from an H. leachii prototype, range 

 throtighout Asia and its nearby islands, the Near East, and the 

 Madagascan archipelago. 



It appears from remarks by Dumbleton (1953), that this tick 

 has not been found in New Zealand since the original record by 

 G. E. Mason (1921 ), that Mason's ticks may have been a different 

 species. Mason *s distributional concepts for this species most 

 probably require revision. 



Note 



In the following list, all available references to "H. 

 leachii " are noted, though it is losually impossible to deTer- 

 mine whether authors are referring to the subspecies leachii 

 or muhsami . I have seen actual specimens of tne subspecies 

 leachii from all geographical areas and from almost all political 

 territories listed below. The following records are those for 

 continental Africa and Arabia. 



As stated above, it is uncertain whether the subspecies 

 leachii occurs outside of the Ethiopian Faunal Region and parts 

 of the Mediterranean Subregion of the Palearctic Region. Analysis 

 of studies of the distribution of this tick will be presented 

 subsequently .
