Owing to the courtesy of my friend, Mr W. F. Cooper, B.A., who 
prepared blood-films and organ smears from various wild animals shot 
by him in British East Africa in August, 1909, I am in a position to 
record three new parasites from the Jackal and Buffalo. Mr Cooper 
prepared the films as soon as possible after the animals were shot, using 
either absolute alcohol or heat for fixation. On arrival in Cambridge, 
the films were stained in the usual manner by Giemsa. 
The Jackal (Ganis cidustus ) was shot to the S.E. and near to Fort 
Hill, about four miles on the road to Punda Milia. The Buffalo (Bos 
caffer typicus ) was shot about five miles to the north of Punda Milia. 
I shall first describe the two protozoal parasites encountered in the 
Jackal. 
The Parasites of the Jackal. 
The parasites were encountered in the course of a very careful and 
systematic examination of eight coverglass smear preparations made from 
the spleen (4) and liver (4) of the jackal. Altogether, the smeared 
coverglasses represented an area of 12 square centimetres and it took 
many days to thoroughly examine them with the aid of a mechanical
