The western half of Bahr El Ghazal is poor, hilly country 

 with iineven rainfall, more or less dense forests with tsetse flies, 

 and few permanent herds of cattle. The eastern half is chaxaLcter- 

 ized by rich dry season meadows, or toich, along the nximerotis rivers, 

 several lakes, and the northern '*Nile sponge'* area that becomes a 

 vast laQce dviring the rains. Large numbers of livestock are main- 

 tained in eastern Bahr El Ghazal and restricted populations of 

 the big game animals of Africa reach their northern limit here. 



REPTILIA 



No records for monitor lizards or tortoises are available 

 from this Province. A number of specimens of A. latum have been 

 taken from cobras and pythons in the eastern s'ector, 



AVES 



Infestations of Francolinus clappertoni by nymphs of A. 

 variegatum in the Forest area are heavier and much more common 

 than those observed in Equatoria. A female H. h. hoodi was found 

 on a tchagra shrike. Near the Kordofan border and near Yirol 

 several adults of R, s, sanguineus and a single male A, lepidtun , 

 respectively, were''ta5en from two greater b\istards. " 



MAMMALIA 



Thirty HEDGEHOGS, Atelerix pruneri oweni , were examined; 

 six were infested by two to four adult R . s, sangtiineus and a 

 total of five male H, leachii muhsami , "A male and female of 

 the latter tick were eilso collected from a hedgehog by Mr, Reld, 



Althoiigh Mr, Reid examined some BATS, no ticks were obtained. 



Among primates, sone fifty GALAGOS, or bushbabies, examined 

 by Dr, T, Work and the writer were uninfested, A nvunber of 

 BABOONS from several large families throughout the Forest were 

 also free of ticks, but all old male hobos wandering alone were 

 infested by severad to two hundred adult R. £. siraus, British 

 Museum (Natural History) collections contain a few adult R. _3. 

 seaiguineTis from a baboon at Kenisa (on the Bahr El Ghazal _
