510 FAMILY: TRYPANOSOMID^ 



T. rhodesiense, and concluded that the similar form in the game was also 

 T. rhodesiense. Kleine and Taute, however, in Tanganyika referred to the 

 human form as T. rhodesiense, but believed that that which occurred in 

 domestic animals and game was another species— namely, T. brucei. 

 According to them, a reservoir host of T. rhodesiense has not been dis- 

 covered. This subject will be referred to in more detail below. 



There seems to be little evidence that T. evansi (including several 

 named species of trypanosome which appear to be merely races of 

 T. evansi), which has a wide distribution in tsetse-free areas of the Old and 

 New World, and which infects cattle, horses, mules, donkeys, camels, and 

 elephants, has any reservoir comparable with the game reservoirs in Central 

 Africa. It has been supposed that the buffalo or pig may act in this 

 capacity in India, while in South America it has been stated that one form 

 (T. venezuelense) occurs naturally in the dog, monkey, and capibara, and 

 another {T. equinutn) in the last-named animal.
