informed us of being bitten by ticks but failed to preserve the 

 specimens. No infestation of indigenous people was observed. 



Ticks actually feeding on man at Torit and Ikoto were nymphal 

 A. variegatum and R. appendiculatus , female R. pravus and R. s. 

 siimis , and male R. pravus , R. s. sangxiineus ,"'and R. s. siiTius;""the 

 last named tick was also recorded at Juba. The nympE of R. appen- 

 diculatus taken from the leg of one of our party at Torit''the day 

 after returning from Kajo Kaji is of especial interest since the 

 parasite tindoubtedly attached at Kajo Kaji, some three hundred 

 miles from Torit. 



Ticks removed from human beings but not attached were advilts 

 of the three rhipicephalid species noted above. A male R. s. 

 sanguineus "from man" at Khor Lado was presented by Mr. ^eid. 



STRUCTURES 



HUMAN DWELLINGS 



Three specimens of the African relapsing fever vector, 0. 

 moubata, were collected in a hut at Liria (cf. page 121). Others 

 have been taken in a hamlet in the Kajo Kaji area and reported 

 from "four Equatoria Province rest houses north of Nimule" . 



Ixodids were frequently observed in houses but the on]y one 

 retained with data was an adult A. lepidum . 



POULTRY HOUSES 



Wherever chickens are confined in any numbers in Juba, Torit, 

 and Eastern Districts A. persicus can be found. Few specific 

 data were retained but numerous casual observations were made. 



PIGEON CCfTE 



A cote at Juba twice yielded a few A. reflexus but additional 

 material could not be found on subsequent visits. Other cotes at 

 Juba were uninfested. Pigeon cotes elsewhere in the Sudan were 

 not investigated.
