Haplosporidium chitonis (Lankester) (Fig. 143, a, b). In the 

 liver and connective tissue of Chiton, Craspido chilus cinereus. 

 The spore proper is oval and measures 10 microns by 6 microns. 

 With two prolonged projections of envelope. 



Haplosporidium limnodrili Granata (Fig. 143, c). In the gut- 

 epithelium of Limnodriliis udekemianus. The spore measures 

 10 to 12 microns long by 8 to 10 microns wide. 



Haplosporidium nemertis Debaisieux (Fig. 143, d).- In the 

 connective tissue of Lineus bilineatus. The spore is oval with a 

 flat operculum, but without any projections, and measures 7 

 microns by 4 microns.
