3- H. cynomolgi. —In Macacus cynomolgus. The 
red cell is stippled. Dividing forms have eight to 
thirteen merozoits. 
4. H. kochi. —In chimpanzees and monkeys. The 
forms usually met with are sexual forms. Asexual 
forms resembling young malignant tertian parasites 
are rare. Flagellation can be seen in fresh specimens. 
The parasites in the fresh film are spherical pale 
bodies containing brownish-yellow pigment. On 
staining, two types can be distinguished. The male 
(mikrogametocyte), pale homogeneous blue with 
much chromatin; the female, deep blue, granular, 
with little chromatin. 
No temperature changes occur in the infected 
animals. The infection is not transmissible by 
inoculation (cp. halteridium). 
Post-mortem. —The spleen is pigmented, the 
capsule thickened. Pigment also occurs in the 
marrow. 
5. [ H . bovis]. —Parasites in the blood of cattle, 
described by Kolle in South Africa. They have a 
general resemblance to malaria parasites, but are quite 
distinct from Piroplasma bovis. They produce remit¬ 
tent fever and severe anaemia, but not haemoglobin- 
uria. Kolle also describes pigment in red cells 
(independently of parasites), but what this means is 
not clear.* 
6. H. vassali. —In the squirrel ( Sciurus grisei- 
manus ); the larger forms are pigmented. The red 
cells are unchanged. Male and female gametes also 
occur. 
7. H. (?) talpae. —These parasites in the mole 
more or less completely fill the red cell, a mere shell of
