Fig. 1 shows a medium sized Idhyosporidium enclosed in a nest of 

 connective tissue, the protoplasm is vacuolated towards the 

 centre. Through an error in drawing, the nuclei have been 

 made too small. 



Fig. 2. Idhyosporidium with homogeneous protoplasm, and large evenly 

 distributed nuclei. 



Fig, 3, Parasite issuing from its cyst. The nuclei are arranged towards 

 the centre of the animal. The protoplasm shows vacuoles. 



Figs. 4 and 5. Division of the nuclei. 



Fig. 6. Group of young individuals. 



Fig. 7. Exit of parasite from its cyst. 



Fig. 8. Abandoned cyst filled with connective tissue. 



Figs. 9 and 10 illustrate the breaking up of an individual into repro- 

 ductive bodies. 



Fig. 11 shows the results of this breaking up process. The young 

 individuals have already begun to grow. 



Fig. 12. Section through a nodule with one of the large worm-like 

 individuals. It has been cut in several places, thus giving 

 the appearance of several separate creatures. 



At P a stage in the process of plasmotomy may be seen. 



Fig. 13. Early stage in the exit of one of these large forms from the cyst.
