or (CNm) for Chicago Natural History Museiun collections. Since 

 King's (1926) review, only two literature references for ticks from 

 definite localities in Bquatoria Province have been published and 

 these have been noted, following the month of collection, in the 

 usual literature reference manner. 



Most Equatoria Province collecting localities may be located 

 in Figure 317. Common names of hosts may be found in Chapter V. 

 The situation of a few of King's early collecting localities can- 

 not now be definitely ascertained, but they are all close to the 

 present Uganda border. 



Reasons for special reference to Bqviatoria Province are several. 

 My Sudan collection is largely from this Province, and it is from 

 here that most of the new data presented in this report have been 

 obtained. Also, Bquatoria Province represents the northern limits 

 of a n\jmber of truly tropical African species. Of these, a few un- 

 doubtedly range into Bahr El Ghazal and Upper Nile Provinces, 

 though they are not yet recorded from these areas. 



Ticks now known from the Sudan nxmber 62 identifiable species 

 plus two additional subspecies. Of this total of 64. identifiable 

 forms, 52 occur in Bquatoria Province. Twenty-five are presently 

 recorded only from Bquatoria Province and five are known only from « 

 Bahr El Ghazal Province. Two uncertsdn forms are also listed. 



DISTRIBUTION IN THE SUDAN 



Under DISTRIBUTION IN SUDAN all known collecting localities 

 have been listed for each species by Province, with the exception 

 of course, of Equatoria Province, which is separately considered. 

 Besides my own collections, the chief source of this information 

 has been the collections of the Stidan Government, for which H. H. 

 King, R. Cottam, W. Ruttledge, D. J. Lewis, and a few other persons 

 have been largely responsible. 



Specimens submitted to me for identification by the Sudan Vet- 

 erinary Service have been important for data on species parasitizing 

 domestic animals. British Museum (Natural History) collections have 

 contributed additional information for areas outside of Bquatoria 

 Province. Almost no other Sudan data have appeared in literature, 

 except for a few papers by King, one or two by Ruttledge, and brief 

 notes by Balfour and a few other persons.
