The structure and behaviour of cysts of a single strain of produced in different cultural conditions were investigated. There appeared to be a gradation from the type of cysts with a wrinkled cyst wall, which were produced in monoxenic culture and in replacement medium, to the smooth, refractile cells, lacking a distinct wall, which were produced in a growth medium supplemented with MgCl.

The results are discussed in relation to the use of cyst structure as a criterion for classifying the various species of
