Phases of Caryotropha mefnilii, Siedl. (par. Polymnia nebulosa). a, young schizont in a 

 cluster of spermatogonia ; the host-cell (represented granulated) and two of its neighbours are 

 greatly hypertropliied, with very large nuclei, and have fused into a single mass containing the 

 parasite (represented clear, with a thick outline). The other spermatogonia are normal. " 6, 

 full-grown schizont enclosed in the hypertrophied host-cell, with an enormous nucleus, which 

 appears to be connected with the nucleus of the parasite by a band of granules, c, intra- 

 cellular .schizont divided up into schizontocytes. rf, each schizontocyte giving rise to a cluster 

 of merozoites arrangnd as a "corps en barillet." e, intracellular microgametocyte divided into 

 microgametocytes of the second order, each of which is forming numerous microgametes. /, 

 niicroganietes in front and side view, spy, spermatogonia; h.c, host-cell; AT, nucleus of host- 

 cell or cells ; n, nucleus of parasite ; , schizontocyte ; tnz, merozoites ; mgc, microgametocytes
