DONKEIS are heavily Infested by R. e. evertsi. Found on 

 them in lesser niunbers are nymphal A. ~vairiegatum , and adiilts of 

 B. annul atus , B. decoloratus, H. rtiTipes , and H, truncatum . 



A PIG at Wau (August) was infested by five male and two fe- 

 male A. variegatoim and a pair of adiilt R. s. simus . 



DOGS throughout the Province are almost invariably infested 

 by several specimens of R. s. sanguineus and some serve as host 

 for dozens of nymphs and"adults. Rare adults of R. s. simus and 

 H. 1. leachii and nymphs of A. variegatum were also found at 

 various localities. A number of female B. decoloratus from 

 Dinka dogs at Fanjalc indicate that where~dogs and cattle sleep 

 in the same hut the former are attacked by the latter »s para- 

 site. 



CATS at the Forest and at Wau provided a few specimens of 

 H. leachii muhsami . 



CATTLE were observed in all areas shoirfn on the map (Figure

Dinka long-horn cattle are regarded with religious fanaticism 

 by their owners. During the dry season the young tribesmen and 

 their great herds migrate to the toich, low lying pastures along 

 the rivers that are intindated during the floods. At the onset of 

 rain they return to their homeland for grazing. People, dogs, and 

 cattle sleep together around the campfire or in huge, smoke filled 

 huts. It was estimated that a quarter of a million cattle passed 

 the Jut Narrows area, in which the Galual-Nyang Forest is situat- 

 ed, on their annual trek to the toich, but no estimate of the total 

 livestock population of this Province is available. For twelve 

 ronths, 1950-1951, the Veterinary Department reported 64,031 

 hides from Bahr EL Ghazalj in contrast, only 775 from Bquatoria. 



Cattle are almost always parasitized by variable numbers 

 of A. variegatum. The infestations are commonly moderate but 

 not-inPrequentiy heavy, as many as fifty to a hundred ticks being 

 found on a single animal. During the dry season the proportion 

 of females to males is in the range of one to five hundred, but 

 late in April it becomes one to fifty, and in Jvily and August
