(iii) Segmenting forms as in Haemamoeba 

 relicta (Proteosoma). 



The protoplasm contains no pigment but 

 refractile granules. 



This differs from the typical development of 

 haemogregarines, and it is probable that its posi- 

 tion requires revision. According to Hintze, it is 

 a variety of H. ranarum.

 Refractile Granules 



3. H. magna. — Described by Grassi and 

 Feletti in R. esculenta. Minchin thinks it may 

 be the makrogamete of H. ranarum or H. monilis. 



In frogs not uncommonly 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 Cytamoeba, they are 

 considered by Laveran to be bacterial in nature. 



4. H. riedyi. — Occurs in a Californian 

 Salamander, Batracheseps attenuatus. 



5. H. stepanowi. — It is found in the tortoise, 

 Cistudo europaea. This may be taken as the type 

 haemogregarine. It presents the following forms

 long. Curved and thickened at each end,
