A ROAN ANTELOPE at Kaka supplied four male A. lepidum and 

 one female R . s . simus . A TORA HARTEBEEST on the Daga-Kigllle 

 track yielded "a. few female B. decoloratus. 



MAN 



Two male R. s. sanguineus feeding on man at Mel\it were 

 sent for identificatxon. 



DQ^ESTIC FOWLS 



Argas persicus has been recovered at Malakal. 



DCMESTIC MAMMALS 



HORSES, DONKEYS, and MULES are attacked chiefly by R. evertsi 

 but several collections including A. lepidum and B. decoToratus 

 have also been made and others contain K. s. sanguineus and B. 



annulatiis . 



iguine 



A PIG at Maban was infested by two B. decoloratus and three 

 R. e. evertsi . " 



DOGS at Er Renk and Bor were the source of two unusual tick 

 records, one female Ixodes nairobiensis and one male R. super- 

 tritus having been secxired by King. THe first tick is the only 

 one of this species known from the Sudan and the second, not inown 

 from other specimens in this Province, is rare wherever it occurs. 

 Infestation by H. 1. leachii is known only from So bat; special 

 efforts made to~secure this tick at Malakal were unsuccessful. 

 R. s. sanguineus is represented in all collections. 



CATTLE density, breeds, and handling habits here are in 

 general similar to those of Bahr El Ghazal and long east-west 

 migrations are xmdertaken in search of grazing. Herds observed 

 in Upper Nile were invariably parasitized by A. variegatum and 

 B. decoloratus . Frequently included were smaTler numbers of A. 

 Tepidxxm , B. annulatus , H. ruf ipes , R. e. evertsi , R. s. sanguineus , 

 and R. s. simus . Inclusion of the Tas^ two rhipiceptialids, not 

 ordil^xly fo\ind on cattle in the Sudan, is difficult to explain, 

 yet several collections from different localities contain a nuniber
