Morphology and schizogonic cycle ofHæmoproteus raymundi N. SP., parasite ofLeptocoma zeylanica (Lin.)

Leptocoma Zeylanica (Lin.) is parasitised by a Hæmoproteus which we consider a new species and nameH. Raymundi. The interest lies in its particularly simple schizogonic cycle. Merozoites arise as a result of the nuclear division of free trophozoites and the former remain free among the cells of the host tissue. They finally attack the red blood corpuscles as schizonts. In spite of careful research, we have been unable to detect an intracellular stage at any phase of the schizogonic cycle.
