Eala. 
The trypanosomes observed, with one exception, are of the long 
type, with a well-defined free flagellum. The exception measured 
I4M i n length by 9/x in breadth, and conforms in all respects to the 
“ tadpole ” type. In these parasites the blepharoplast was of 
comparatively large size. Parasites of the “ long ” type in the process of 
longitudinal division were seen in preparations of the peritoneal fluid. 
In fresh preparations this trypanosome moved so rapidly that it was 
extremely difficult to keep it in the field of the microscope. By its 
rapid movement this parasite recalls the description of Trypanowu 
vivax by Ziemann. 20 We are, however, satisfied that it is the “long" 
form of I rypanosoma dimorphon. 
Nouvelle Anvers. 
The parasites conform to the description of the “ tadpole " variety. 
One trypanosome of the “ stumpy ” variety, measuring I9'2 by i'9/r, 
was also found. In the one sub-inoculation the trypanosomes did not 
show any changes. 
ROMEE. 
The parasites are of the extremely short “ tadpole ” variety. In 
the direct sub-inoculations the parasite preserved the same 
characteristics with considerable constancy. In two cases (Exps. 148 
and 151), in addition to the very short forms, trypanosomes 
corresponding to the “ stumpy ” forms made their appearance. The 
same holds good with regard to the second passage. This fact is of 
some importance. Dividing forms of the usual longitudinal type were 
observed in all the sub-inoculations. 
Lokandu. 
1 rypanosomes of the first two types (the “ tadpole ” and “ stumpy” 
forms) were found in these cattle. The short “ tadpole ” forms were 
very much more common than the “ stumpy ” type. 
Sendwe. 
The parasites agree in all respects with the “ tadpole ” type. The 
examination was rather restricted, however, as the parasites were very 
scanty and only a few preparations were available. 
Kasongo. 
In the cow, Moiuma (No. 33), the trypanosomes are of the third, 
the “ long,” type, and possess a well-marked flagellum. In many of
