its staining reactions with Romanowsky, and 

 because it is pigmented. It somewhat resembles 

 the quartan parasite (Fig. 68). 



5. //. wwnwMs(polychromophilus murinus). — 

 Found in the blood of Vesperiilio murinus. It 

 is also pigmented. It shews like the former a 

 variety of ' polychrome ' effects with Roman- 

 owsky. In this, as in the former, Dionisi 

 figures a great variety of forms (Fig. 68). 



6. H. vesperuginis (achromaticus vesper- 

 uginis). — In the blood of Vesperugo noctiila. The 

 young forms . resemble those of the malignant 

 tertian parasite (Fig. 68). It occurs in large 

 numbers in the blood, but forms no pigment 

 during its development. It produces considerable 

 anaemia and degenerative changes in the red 

 cell. 



How bats are infected is quite unknown. 



The parasite ' find ' differs according to 

 whether the animal is hibernating or not. 



Haemamoebae in Cattle 



7. [H. bovts]. — 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 

 bovts. They produce remittent fever and severe 

 anaemia, but not haemoglobinuria. Kolle also 

 describes pigment in red cells (independently 

 of parasites), but what this means is not clear."*
