Three genera have been assigned to the Astylozoonidae: Astylozoon Engelmann (106; 

 Fig. 7. 43, D), Geliella Stiller (106; Fig. 7. 43, F), and Hastatella Stiller (95, 106; Fig. 

 7. 43, G). 



Family 2. Epistylidae. In sessile stages, the scopula produces a stalk 

 which contains no myoneme (stalk-muscle). Some species are solitary and 

 others colonial.
