been examined in British Museiim (Natural History), contain both 

 B. decoloratus and B. annulatus . 



B. annulatus is a North American cattle tick that one may 

 assume originally parasitized deer and buffalo. It also has been 

 introduced into the Mediterranean basin. In North Africa and the 

 Near East, it freqiiently is referred to as B. calcaratus (Birula, 

 1894), to which Minning appended several suBspecies. THese all 

 appear to be the same as American and African populations of B. 

 ann\ilatu3 . The name also has been used by students of the Oriental 

 f avma but examination of pertinent specimen material is indicated 

 to establish the validity of these identifications. 



Records presented below are the only ones from Africa that 

 are known to pertain to B. annulatus, with a few additional, an- 

 notated references that might be pertinent. Quite possibly other 

 isolated populations are maintaining themselves outside of the 

 presently recognized range of the Texas fever tick in the Ethiopian 

 Faunal Region, having been introduced on cattle from West or North 

 Africa, the Near East, or North America.

 /~PCRTUGESE GUINEA: B. (= Margaropus ) annulatus listed by Monteiro 

 da Costa (1926) and Sant'anna Barreto (1929 J; quoted by Tendeiro 

 (I95IA), but not subsequently repeated in faunal lists by this 

 author although it would not be surprising to find this tick here_.7 



NOTE: Records below are for "B. congolensis" . 



CENTRAL AFRICA : FRENCH EQUATCRIAL AFRICA (Minning 193^. 

 Rousselot 1953B. Theiler and Robinson 195if^). CAMEROONS (Rageau 

 1953A,B). BELGIAN CONGO (Theiler and Robinson 195A. Minning 1934- 

 stated, apparently as a guess, that the B. annulatus calcaratus 

 specimens of Newstead, Button, and Todd 1907, from Coquilhatville, 

 are '"B. congolensis' "). 



EAST AFRICA ; SUDAN (Hoogstraal 195AB,C. Balfour 1911F 

 referred to ""B. australis '" in the Sudan, but since he also stated 

 that B. decoloratus is absent there his remarks are difficult to 

 interpret J.
