hich is left. The parasite is oval, the protoplasm 

 stains a light blue, and the nucleus shews a loose mesh- 

 work of chromatin. We have often observed these 

 bodies in the blood of moles, but have considerable 

 doubts as to their parasitic nature and as to their 

 inhabiting red cells. 



HAEMAMOEBAE IN BATS 



1. H. murinus. In Fespertilio murinus shews ring 

 forms, medium forms, male and female gametes and 

 sporulating forms. The spores are twenty to twenty- 

 two in number and of an irregular angular shape. 

 The sporulating forms are found almost entirely in 

 macrophages in the liver. This parasite is pigmented 

 and causes enlargement but no stippling of the red 

 cell. 



2. H. melani-pherus. In Minio-pterus schreibersii 

 has a general resemblance to the quartan parasite. 

 Gametes are the forms most commonly found, though 

 young and medium forms also exist. Sporulating 

 forms are unknown. The red cell is unchanged. 

 During hibernation, only gametes are found in the 

 blood. 



3. H. ves-peruginis. Occurs in the blood of various 

 species of bats. It is unpigmented. Minute spindles, 

 rings, large forms and Piroplasma-like forms occur. 

 It produces considerable anaemia and degenerative 

 changes in the red cell. It possibly is a Piroplasma. 

 It is possible that these parasites are conveyed by 

 wingless flies, of the family Nycteribiidae which occur 

 on bats. In V . capensis, the South African Serotine 

 bat, haemamoebae also occur. 



4. H. monosoma. In Fesperugo, sp., in Annam : 

 sexual forms only are known.
