(2) T. vespertilionis (Battaglia, 1905) in V. noctula 
and other bats in Portugal, 8-12/^. 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. 7 *. suis (Ochmann, 1905), in pigs 
in East Africa ; very short and thick, and with very 
short flagellum. 7 *. congolense (Broden, 1904), in 
sheep in the Congo, 10-15/^, with no free flagellum. 
7 ". {jinjaense ), in cattle in Uganda (probably = 7 ". 
brucei ), T. {asino-cab alii) in mules in Uganda. 
All these are pathogenic. We have also 7 *. talpae 
in the mole, and 7 ". cuniculi (R. Blanchard, 1906) in 
the rabbit, and 7 \ pestanai (Bettencourt and Franca, 
1905) in the badger ( Meles taxus). 7 \ indicum , (Liihe, 
1906) in the Indian squirrel {Funambulus palmarum ), 
T. spermophili in Russian marmots ( S . guttatus and 
S. musivus ), 7 \ caviae in the guinea-pig, exceedingly 
rare. 
Trypanosomata of Batrachians 
1. T. rotatorium. —Occurs in various species of 
frogs : Rana esculenta , R. temporaria , Hyla arborea, 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^. Blepharoplast about 2 ^ from posterior end.
