monkey, Ateles pentadactylus, of French Guiana, It is a small trypano- 

 some with a body 14 microns in length and a flagellum 5 microns long. 

 The kinetoplast is large and round, and situated 3 microns from the 

 posterior extremity. There is a well-developed membrane. 



T. devei Leger and Porry, 1918. — This form was found in Midas midas 

 in French Guiana. It is a long, thin trypanosome, the body of which 

 measures 37 microns and the flagellum 7 microns. The breadth is 2 to 

 2-5 microns. The kinetoplast is some distance from the posterior end of the 

 body, and there is a well-developed membrane. It is of the T. leivisi type. 



Brimont (1909) discovered a trypanosome in a howler monkey {Alouatta 

 senicula) captured in French Guiana (Fig. 203,3). Oiily a single trypano-

 occupied 9 to 10 microns. 



In Africa, in endemic centres of sleeping sickness, trypanosomes have 

 been noted by several observers in monkeys. They have generally been 

 regarded as-T. gambiense. Ziemann (1902a) recorded a trypanosome in 

 a chimpanzee in the French Congo, Kudicke (1906) a large trypanosome 

 in Cercopithecus sp, in German East Africa, and Button, Todd, and 

 Tobey (1906) one from C. schmidti of the Belgian Congo, which measured 

 about 25 by 2-5 microns. Martin, Leboeuf, and Roubaud (1909) saw a 

 trypanosome in a lemur (Galago demidojffi) of the French Congo, while 

 Koch, Beck, and Kleine (1909) observed a trypanosome in a captured 

 monkey, and regarded it as T. gambiense, as also did Bruce et al. (1911<^).
