Small embryonal mass which has assumed an ovoid form, and sub- 

 sequently becomes concerted into a kind of Paramecium {c'). 



Similar mass, rather larger, which becomes flattened, and subse- 

 quently develops into an embryo Chilcdon {d'). 



A complex egg-like body into which individual embryonal spheres were 

 very prone to develop ; the central mass of protoplasm containing 

 large granules and a vacuole. 



Later stage of same body— central mass of fatty-looking globules, 

 which subsequently becomes homogeneous and enclosed within 

 another cyst, as in g. 



Later stage of development as seen in a few embryos, w^hich may or 

 may not have escaped from their loose outer envelope.
