HOSTS 



The black rhinoceros, Diceros bicornis subspp. , and the white, 

 or sqiiare-lipped, rhinoceros, Ceratotheritun simum subspp,, are 

 listed as hosts by all authors. The hosts of our Equatoria Prov- 

 ince specimens listed above, if they were rhinoceros, represent 

 both genera inasmuch as only the black rhinoceros occ\irs near Magwe 

 east of the Nile and only the white rhinoceros occvirs across from 

 Nimule west of the Nile, 



In Tanganyika each of several rhinoceros hosts of various ticks 

 yielded small numbers of this species (J. B. Walker, unpublished). 



King (1926) suspected, from the places in which he found spec- 

 imens of this tick, that it may also attack the hippopoteunus , 

 Evans (1935) recorded domestic cattle and sheep as hosts in Tanga- 

 nyika, Lewis (1934) mentioned a domestic donkey in Kenya sind De 

 >feza (191 8A) took specimens from domestic cattle in Nyasaland aiid 

 from elephants in Tangsinyika, Neumann (190X,1910B) listed an 

 eland as host, and Mettam (1932) noted the jackal from Uganda,

REMARKS 



That the specific name rhinocerotis de Geer (1778), used by 

 many authors for this species, actually applies to a distinct 

 species in the genus Amblyorama was indicated by Donitz (19IOB), 



Schulze (1932A) suggested that D. rhinocerinus be placed in 

 the genus Amblyo center on the basis of minor morphological pecu- 

 liarities. There is, however, little utility in fragmenting tick
