2. ravus is known only from Eastern and Torit Districts of Equatoria Frovince. Although absent or rare west of Torit District, apparent ecological preferences indicate that it may be expected to occur in Upper Nile Province, to the north of eastern Equatoria.
Some of the above_mentioned collections have already been quoted by Theiler and Robinson (19533) and Walker (1956). Eccept for a few Kapoeta specimens, none from the Sudan have been found in Sudan Government collections or in British Museum (Natural
The drier areas of East Africa appear to be the center of
distribution of E. ravus, which also extends into Central and Southern Africa and may range just inside the borders of West Africa. This species is often common in the localized areas
where it occurs.

Note: This species has undoubtedly been much misidentified, but more records for it will probably appear since Zumpt's, Theiler's, and Walker's recent works have established its identity. Many or most records of R. bursa from tropical and South Africa pertain actually to R. Eavus according to Theiler and Robinson (l953B), but Lewis‘ various references to R. bursa in Kenya refer
to R. kochi. and to R. hurti Wilson, 1954 (Walker 1956) as well as to _R. p_1_'avus.
R. avus is rather more indiscriminate in choice of hosts than moss other rhipicephalids, being common on domestic cattle, sheep, goats, and dogs, equally connnon on many antelopes and carnivores, and not at all uncommon on hares. Several incidental hosts, from a bird to an elephant, a.nd including man, are listed below. Immature stages utilize rodents and insectivores as hosts.
Domestic animals: Cattle (Wilson 1950B, Unsworth 1952, Theiler § Robinson 1953B; Sudan records above; Hoogstraal Eritrean collections.
