THE HAEMOCYTOZOA Continued, 



The haemocytozoa, or endoglobular haematozoa, 

 are divided by Laveran into three genera :* 



I. Genus Haemamoeba. 2. Genus Haemo- 

 gregarina. 3. Genus Piroplasma. 



GENUS HAEMAMOEBA 



Endoglobular parasites, generally pigmented with 

 two generations, an asexual of multiplication and a 

 sexual of reproduction. 



The genus Haemamoeba includes the malaria 

 parasites with which we have already fully dealt. 



HAEMAMOEBAE IN MAMMALS 



1. H. pithed. In the ourang-utan the young 

 forms resemble malignant tertian. The gametes in 

 form and in their pigment resemble quartan, while 

 schizogony forms resemble those of simple tertian. 

 The red cells are stippled. It is not transmissible 

 to other apes. 



2. H. inui. In monkeys, Macacus cynomolgus and 

 M. nemestrinus ; resembles the former parasite but the 

 pigment is very abundant and light yellow in colour. 

 The red cell is not stippled. Segmenting forms with 

 twelve to sixteen merozoits. 



* In the imperfect state of our present knowledge this classification is for the 

 present retained.
