‘ Gytamoeba bacterifera .’—In frogs not uncom¬ 
monly curious rod-shaped bodies are found lying in a 
vacuole in the red cell. When these occur further 
search will show cysts filled with these rod-like bodies. 
Originally described as protozoan parasites, they are 
considered by Laveran to be bacterial in nature. 
4. H. berestneifi. —In frogs in Bombay. Resembles 
H. magna . Encapsuled and free vermicules occur. 
The latter have the nucleus near the blunt anterior 
end. 
Fig. 83. (1) Hg. magna ; (2) ‘ Cytamoeba bacterifera ’ 
5. H. theileri. —In R. angolensis in the Transvaal. 
Large haemogregarines, 15 to 17 by 5 to 6 ^ (Fig. 84). 
(1) They are oval, spindle-shaped, or with one end 
slightly recurved. Some lie in a cavity which may 
either be a cyst or only a cavity in the red cell. (2) 
Vermicule free forms, 24 by 4/x, also occur. The red 
cells are much altered and their nucleus may be divided 
into two parts. 
6. H. neireti. —In R. mascariensis. They are 
oval in shape. 16 to 21 by 11 to 14yu. The nucleus 
is elongated and set at right angles to the axis of the 
haemogregarine. The largest forms have one end 
slightly recurved (Fig. 84).
