from the Boma Plainsj fifteen male A. lepidum were taken from the 

 same animal, along with twenty R. sT simus , eighteen R. simus 

 Senegal ensis , a single R. s. sangr^neus, and 55 A. variegatum. 

 Variable niunbers of this last tick infest alma st^e very buffalo 

 on the east bank of Biuatoria Province. Small nximbers of H. 

 rufipes and H. tmncattim on a few buffalos in this Province 

 are m striloing contrast to the high rate and density of infes- 

 tation by these ticks in northeastern Bahr EL Ghazal Province. 

 In eastern Equatoria, infestations of R. s. simus are most com- 

 mon next to those of A. variegatum. in Juba and Yei Districts 

 smaller numbers of R. ~composiiu3 , ^. longus , and R. supertritus 

 have been collectecTfrom Dviffalos." ~ 



Possibly the most interesting data resulting from listing 

 the antelopes below are the generally low or moderate numbers 

 of ticks infesting them on the east bank of Equatoria Province. 

 Had more collections been obtained during the rainy season, the 

 rate and density of infestation might have been somewhat higher. 



TRAGHAPHUS 3CRIPTUS BCR Heuglin, 1877. Nile Bushbuck. 



Several bushbucks obtained near Nimule were uninfested. 



TAUROTRAGUS DHIBIANUS GIGAS (Heiiglin, 1863). Derby's Giant Eland. 



Near Meridi, five adult B. annulatvis and thirteen adult B. 

 decoloratus were taken from a''giant eland. 



TAUROTRAGUS (BYX PATTHISONIANUS Lydekker, 1906. East African 

 feland. 



An eland at Loronyo bore a female A. lepidiun and a pair of 

 adults and seven nymphs of A. variegatum. Single adiilts of R. 

 s. simus were the only ticks found on two elands near Torit and 

 l^idepo. At Tarangore another yielded four adult R- £• sanguineus 

 and one at Terakeka a single adult R. e. evertsi. 



CEPHALOPHUS GABIULUS MUSCULOIDES Heller, 1913. Eastern Blue Duiker. 



Blue duikers are not uncommon in the moxintain forests east 

 of the Nile but they are difficult to obtain. A female H. 

 parmata has been taken from an animal in the Noli Hills.
