In the Sxidan, R. appendlciilatus is known only from Kajo Kaji 

 and Yei on the west"'bant of Bqtiatoria Province and from Katire 

 (3500 feet elevation) and Ngangala (-1700 feet elevation) on the 

 east bank of Bquatoria Province (Hoogstraal 195^) . 



The engorged nymph removed at Torit ftom the leg of one of 

 our party who had jxost come almost three htmdred miles from Kajo 

 Kaji is a good example of how an important tick species may easily 

 be spread far from its present range by modem, fast, transporta- 

 tion. 



There appears to be little reason why R. appendiciilatus should 

 not be able to maintedn itself east of the l?ile In certain scattered 

 areas of Torit District, though as yet it has been found only at 

 Katire, which is cooler and more forested than are the plains. To 

 the east and north of Torit District, conditions are most likely 

 too arid for the brown tick. Most of the west bank of Bq.uatoria 

 Province is probably suitable for this tick.
