KH/^,RTQUM PROVINCE * 



Khartoum Province, a small area aroxmd the capital, Khartoum, 

 industrial town, Khartoum North, and residential and marketing 

 center, Omdurman, is a region of poor grass acacia scrub with no 

 special biological features except for snail, irrigated gardens 

 along the Nile. Large numbers of horses, donkeys, camels, sheep, 

 and goats live here or come into the Province, and some cattle 

 are maintained. 



The presence of a zoological garden and of a cattle quaran- 

 tine station brings many wild and domestic animals with a large 

 variety of ticks into the Khartoum area and several exotic rec- 

 ords for this locality appear to have been based on material of 

 species not established in this Province. 



AVES 



King reared H. rufipes from nymphs from a KITE, Milvus 

 migrans . Adults of R . s . sanguineus were found on another kite. 



*Khartoura data derive from the vrriter's collections, a few lots 

 in Sudan Government collections, and four lots sent by Sudan 

 Veterinary Service personnel .
