TRVPANOSOSIIASIS 273 



4. Mai de caderas of South Africa. It affects horses, 

 asses, cattle, hogs and certain other animals, and is attributed 

 to Trypanosoma cqiiuium. 



5. Rat irypanosomiaiis 2i\Xx\h\\\.e.$i.\.o Trypanosoma Lewisi. 

 By some authors this parasite is alleged to be identical with 

 the horse surra organism, but it is quite certain that rats maj- 

 harbor a distinct species. 



Until the results of further investigations are recorded it 

 is deemed best to consider these as distinct infections.
