Extract

1. A description is given of a sporozoan parasite occurring in the coelomic fluid of P. minutum.

2. The four stages described include two types of schizonts (each enclosed in a tough envelope), merozoites, trophozoites, and encysted gamonts. The schizonts occur in the haematids of the coelomic fluid, the ‘cysts’ in amoebocytes.

3. The life history and possible affinity of the parasite with the Haemogregarinidea are discussed.

4. Attempts to verify the suggested life history by experimental means are described.
