Family 1. Pseudosporea [Pseudosporeae] Berlese in Saccardo Sylloge 7: 460 

 fl888). Monadineae Zoosporcae Cienkowski in Arch. mikr. Anat. 1: 213 (1865). 

 Family Pseudosporeen Zopf Pilzthiere 115 (1885). Orders Azoosporidea for the 

 most part and Zoosporidca Delage and Herouard (1896). Azoosporidae for the most 

 part and Zoosporidae Doflein Protozoen 40, 41 ( 1901 ) . Family Pseudosporidae Poche 

 in Arch. Prot. 30: 197 (1913). Amoeboid organisms without shells or skeletons, the 

 pseudopodia tapering from a broad base to a filamentous termination. Flagellate 

 stages (with one flagellum or two unequal flagella) occur in Protovionas, Pseudo- 

 spora. and Diplophysalis. In other genera, as Arachnula and Chlamydomyxa, no 

 flagellate stages are known. 



Family 2. Lagynida Schultze 1854. Order Gromida Claparede and Lachmann 

 1859. Family Gromida Carpenter 1862. Family Gromiidae Brady (1881). Families 

 Monostomina and A.mphistomina Lankester (1885). Amoeboid organisms having 

 chitinous shells without siliceous scales with a broad orifice through which project 

 pseudopodia of the character of filopodia. Grom.ia, Lagynis, etc. 



Family 3. Euglyphida [Euglyphidae] Wallich 1874. Amoeboid organisms with a 

 chitinous shell beset with circular siliceous scales, the filopodia projecting through a 

 broad orifice. Euglypha, Cyphoderia, Campuscus, Trinema, etc. 



Family 4. Vampyrellacea [Vampyrellaceae] Zopf Pilzthiere 99 (1885). Monadin- 

 eae Tetraplasteae Cienkowski op. cit. 218. Family Vampyrelleae Berlese in Saccardo 

 Sylloge 7: 454 (1888). Family Vampyrellidae Poche in Arch. Prot. 30: 182 (1913). 

 Cells subglobular, slowly creeping, with slender pseudopodia, numerous, densely 

 packed and stiffly radiating on mature individuals, bearing terminal knobs. Vampy- 

 rclla, the cells colored faintly pink by some metabolic by-product, is not unfamiliar 

 as a predator on freshwater algae cultured under unfavorable conditions.
