 microgametocyte forms first about 100 cytomeres, each with 

 some 20 nuclei; microgametes comma-shaped; anisogamy; oocyst 

 with several hundred spores, each with about 24 sporozoites. 



Genus Hyaloklossia Labbe. Schizogony unknown; sporogony 

 in kidney of marine mussels; oocyst in organ-cavity; spherical 

 spores of 2 kinds: smaller one with 2 spirally coiled sporozoites 

 and the other with 4-6 sporozoites. One species.

 spores Sfx and 11-12/x in diameter; in kidney of Tellina sp. and 

 Donax sp. 



Genus Angeiocystis Brasil. Schizogony unknown; sporogony in 

 polychaetes; oocyst forms 4 spores; spore oval, mth about 30 

 sporozoites and residual body at a pole. One species.
