430 BIOLOGY OF THE PROTOZOA 



3. Genus Hyalospora, Sclineider (1875). Biassociative ; epimerite a small 



knob; cysts open by rupture; endoplasm yellow-orange; sporoblasts 

 ellipsoidal. Gut of Petrobius sp. 



4. Genus Cnemidospora, Schn. (1882). Solitary; protomerite globular 



anterior half gray, posterior half yellow-green, cysts open by simple 

 rupture; spores ellipsoidal. Gut of Glomeris. 



5. Genus Eiispora, Sclin. (1875). Biassociative; no spbroducts; sporo- 



blast prismatic. Gut of Rhizotrogus estivus. 



6. Genus Sphcerocj/stis, L^ger (1892). Solitary; protomerite temporary, 



body spherical, cysts without sporoducts, sporoblasts ovoidal. 



7. Genus Gamocystis, Leger (1892) Schn. (1875). Associative; protomer- 



ite only in young stages, cyst with sporoducts, sporoblasts cylin- 

 drical and elongate. Cock-roach and other insects. 



8. Genus Frenzelina, Leger and Dub. (1907). Biassociative, cysts with- 



out sporoducts, sporoblasts ovoidal with a dark equatorial line, 

 epimerite unknown. 



9. Genus Uradiophora, Mercier (1912). Bi- or triassociative , epimerite 



a simple style forked at end, cysts without sporoducts, sporoblasts 

 dolioform. 



10. Genus Leidyana, Watson (1915). Solitary; epimerite a globular knob; 



cyst with sporoducts; sporoblasts dolioform. 



Family 2. Stenophoridse, Leger and Duboscq (1904). Individuals soli- 

 tary; epimerite absent or a mere knob; cysts without sporoducts, sporo- 

 blasts oval with broad exospore and with equatorial line, sporoblasts not 

 extruded in chains. 



11. Genus Stenophora, Labbe (1899). Gamonts large with rudimentary 



epimerite, sporoblasts with dark sutural Ime, intestine of millipedes. 



12. Genus Oocephalus, Schn. (1886). Epimerite a spherical knob on a 



short conical neck. 



Family 3. Didymophyidae, Leger (1892). In associations of two or 

 thj-ee, satellites without septa. 



13. Genus Didymophyes, Stein (1848). The epimerite has the form of a 



small pointed protuberance, sporocyst without sporoducts, sporo- 

 blasts ellipsoidal, gut of species of Aphodius. 



Family 4. Dactylophoridae, Leger (1892). Individuals soUtary; epimer- 

 ites asymmetrical and irregular with digitiform processes; sporocysts open 

 by simple rupture or by swelling of a residual mass of plasm termed a 

 "pseudocyst;" sporoblasts elongate, cylindrical or ellipsoidal. 



14. Genus Dactylophorus, Balbiani (1889). The protomerite is dilated 



excentrally and bears epimerite with digitiform processes, indi- 

 viduals solitary; sporocysts open by swelling of lateral pseudocyst, 

 sporoblasts cylmdrical and emitted in oblique chains, gut of Cryp- 

 iops hortensis. 



15. Genus Nina, Grebnecki (1873). Protomerite formed of two long and 



narrow horizontal arms turned up at ends, and said to bear a small 

 nucleus (?) , the attaching surface bears teeth from which filaments 

 arise, sporoblasts emitted in oblique chains, gut of myriapods. 



15. Genus Tr ichor hynchus, Schn. (1882). Protomerite truncated, epi- 



merite elongated and conical, sporocysts open by lateral pseudocysts, 

 sporoblasts not in chains, gut of Scutigera. 



16. Genus Echinomera Labbe (1899). Epimerite an excentric cone with 



eight or more short digitiform processes from the sides, sporocysts 

 open by simple rupture, sporoblasts cylindrical and in chains, gut 

 of Lithobius fortificatus.
