(z) T. vespertilionis (Battaglia, 1905) in V . noctula 

 and other bats in Portugal, 8-i2//<. The motion is 

 peculiar, resembling the bending of mosquito larvae. 

 These and other trypanosomes of bats are at present 

 very imperfectly known. 



Other Mammalian Trypanosomes. T. nanum 

 (Laveran, 1905), in cattle in Sudan, with no free 

 flagellum. T. himalayanum (Lingard), 75^ long, in 

 Himalayan cattle. T. suis (Ochmann, 1905), in pigs 

 in East Africa ; very short and thick, and with very 

 short flagellum. T. congolense (Broden, 1904), in 

 sheep in the Congo, 10-15/4, with no free flagellum. 

 T. (jinjaense), in cattle in Uganda (probably = T. 

 brucei), T. (asino- cab alii) in mules in Uganda. 



All these are pathogenic. We have also T . tal-pae 

 in the mole, and T. cuniculi (R. Blanchard, 1906) in 

 the rabbit, and T. pestanai (Bettencourt and Franca, 



1905) in the badger (Meles taxus). T . indimm, (Liihe, 



1906) in the Indian squirrel (Funambulus palmarum), 

 T. spermopbili in Russian marmots (5. guttatus and 

 S. musivus), T. caviae in the guinea-pig, exceedingly 

 rare. 



TRYPANOSOMATA OF BATRACHIANS 



I. T. rotatorium. Occurs in various species of 

 frogs : Rana esculenta, R. temporaria, Hyla arbor e a, etc. 

 It is characterised by extreme variation both in 

 dimensions and in appearance. Thus Franca and 

 Athias describe, in R. esculenta in Portugal, the follow- 

 ing forms, which they consider to be distinct species, 

 but the validity of these and many other trypanosomes 

 with new names, is a matter of doubt. 



la. T. costatum, Var. I : Striated. About 45^ 

 by 25/4. Blepharoplast about 2^ from posterior end.
