11 



Genus 9. Gregarina Dufour 1828:366. Sporonts associated in twos, 

 epimerite a simple globular or cylindrical papilla. Cysts 

 with spore-ducts, spores barrel-shaped, extruded in chains. 



Type: Gregarina ovata Duf. 

 Genus 10. Protomagalhaensia Pinto 1918: ? Sporonts in associations 

 of several individuals, often attached laterally. Myonemes. 

 prominent. Sporonts attenuate. (Cysts and epimerites 

 unknown.) Spores barrel-shaped, spine at each corner. 



Type: Prolomagalhaensia serpentula (Magal.) Pinto. 



Genus 11. Gamocystis Schneider 1875:587. Protomerite only in tro- 

 phozoite, sporonts in twos; sporulation partial, with spore- 

 ducts, spores cylindrical. 



Type: Gamocystis tenax Schn. 



Genus 12. Hyalospora Schneider 1875:583. Sporonts in associations of 

 two, endoplasm yellow-orange. Epimerite a simple 

 globular knob. Cyst dehiscence by simple rupture, spores 

 ellipsoidal. 



Type: Hyalospora roscoviana Schn. 

 Genus 13. Hirmocystis Labb^ 1899:12. Sporonts in associations of from 

 two to twelve (or more). Epimerite a small cylindrical 

 papilla. Cysts spherical, dehiscence by simple rupture, 

 spores ovoidal. 



Type: Hirmocystis venlricosa (L6ger) Labb6. 

 Genus 14. Euspora Schneider 1875:582. Sporonts in twos. (Epimerite 

 unknown.) Cysts spherical, dehiscence by simple rupture, 

 spores prismatic. 

 Type: Euspora fallax Schn. 



Genus 15. Sphaerocystis L^ger 1892:115. Protomerite only in trophic 

 stages, sporonts solitary, subspherical. Cysts spherical, 

 dehiscence by simple rupture, spores ovoidal. 



Type: Sphaerocystis simplex L6ger. 

 Genus 16. Cnemidospora Schneider 1882 :446. Sporonts solitary, anterior 

 half of protomerite gray, posterior half yellow-green. (Epi- 

 merite not known.) Cyst dehiscence by simple rupture, 

 spores ellipsoidal. 



Type: Cnemidospora lutea Schn. 



Genus 17. Uradiophora Mercier 1912 :198. Sporonts in twos, deutomerite 

 with small appendix. Epimerite an elongate papilla. Cysts 

 ovoidal, dehiscence by simple rupture, spores spherical or 

 subspherical, extruded in chains. Development extra- 

 cellular. 



Type: Uradiophora cuenoti (Merc.) Merc. 



Genus 18. Pyxinoides Tr6goubofif 1921: liii. Sporonts in associations of 

 two, epimerite a slightly stalked globular papilla with 

 sixteen longitudinal furrows, small cone at apex. Extra- 

 cellular development. 



Type: Pyxinoides bcdani (Koll.) Treg.
