The Boma Plains specimens constitute the first and only defi- 

 nite record of A. cohaerens from the Sudan, If the tentative inu 

 mature stage icJentif i cations are correct, we may expect that A, 

 cohaerens occiirs in other parts of Equatoria Province, especially 

 where bviffalos roam. The East African buffalo tick has not been 

 found in Bahr El Ghazal or in Upper Nile Provinces, although 

 buffalos are present in these Provinces and frequently have been 

 examined for ticks by H. H, King, Sudan Veterinary Service per- 

 sonnel, and the writer. 



DISTRIBUTION 



A. cohaerens is an East and Central African buffalo parasite 

 that^reaches the northern limit of its range in Equatoria Prov- 

 ince £ind extends southwards into Tanganyika,
