DISTRIBUTION 



Under the heading, DISTRIBUTION, all available pertinent lit- 

 erature records for each political territory of Africa have been 

 listed. I have attempted to select critically each reference for 

 accxiracy of species identification sind to incliide only references 

 based on actiially known specimens in relation to distribution, 

 disease, control, biology,, availability for taxonomic study, etc. 

 Authoritative taxonomists • lists have been inclijded especially 

 where localities are involved and where questions of species iden- 

 tity in any territory exist. Also noted are references by experi- 

 mental workers who have indicated the source of their material; 

 biological variations within populations presently considered as 

 identical species may subsequently prove to be of the utmost im- 

 portance in evaluating results of laboratory experiments. 



While I personally am concerned with these data in the inter- 

 ests of geo medical knowledge, it is intended that these lists should 

 be a usefvil guide to interested persons in the territories concerned. 

 Otherwise, this listing is chiefly for advanced, specialized stu- 

 dents with some knowledge of the literatiore, who should be able, 

 by consulting the reference titles in the bibliography, to locate 

 subjects of interest. After serious consideration, it is felt that 

 further breakdown of these references into subject groups would be 

 too unwieldy and cumbersome. 



Maps showing tick distribution in Africa will be presented in 

 subsequent volumes of this work. 



Every attempt has been made to provide as complete a list of 

 useful references as possible. Probably, all really important works 

 have been seen and noted but if any has been missed it will be much 

 appreciated if readers will call ny attention to it. 



HOSTS 



The object of the HOSTS section has been to indicate the chief 

 references to kinds of animals on which each species feed in each 

 life stage and to give a brief statement concerning the preferred 

 host or hosts. The references following each host do not necessarily 

 include all reports in which the animal has been mentioned. Fvcrther
