'TICK FEVER' IN MAN 
The species is now known as Ornithodorus moubata. As I pointed out in 
1900, it may be distinguished from O. savignyi by the invariable absence of the two 
pairs of eyes present in the latter. Hence it has recently, but quite unnecessarily, 
been renamed by Neumann, 0. Savignyi var. coeca. Neumann records it from the 
Transvaal, etc., so it is evidently widely distributed throughout Central and Southern 
Africa. Dr. Christy's discovery ot the species in Uganda and his testimony as to 
its prevalence almost throughout the country comes as a surprise after the statement 
in Johnston's ' Uganda Protectorate' that he did not remember ' having encountered or 
heard of that poisonous tick,' with which he was well acquainted on the Zambesi. 
It is an interesting fact that the testimony of Drs. Livingstone and Wei.witsch, 
Sir John Kirk, Dr. Dowson, Dr. Daniels, and Sir Harry Johnston, with respect 
to the sickness which follows the bite of this tick, both in Angola and British Central 
Africa, has been independently confirmed by Dr. Christy, who, at the time, did not 
know that the bibo of Uganda is identical with the moubata, tampan, and carpato of the 
Zambesi watershed. I am not aware th;;t the allied species O. Savignyi, which has 
been recorded from Egypt, Nubia, Abyssinia, Somaliland, British East Africa, etc., 
shares the bad reputation of 0. moubata. The geographical areas of the two species 
overlap. Hence, without the examination of actual specimens, it would be impossible 
to say which of the two species is involved in any given case of ' tick-fever.'
