attached by development of a stalk, loses its cilia, and develops tentacles 

 on its upper surface to become a Paracineta-sta.ge (Fig. 7. 56, G). This 

 stage does not feed and apparently is a temporary stage preceding encyst- 

 ment (Fig. 7. 56, H). 



Conjugation, comparable to that in typical ciliates, has been described 

 in several genera, including Acineta (148), Dendrocometes (86), and 

 Tokophrya (156). In contrast to conjugation in Tokophrya lemnarum,
