brella shaped with radiating ridges. The spores, which 

 are biconical, have central swellings. The epispore 

 opens at the equator by simple dehiscence; the endo- 

 spore opens terminally. Typical genus, Sciadiophora 

 Labbe, 1899. 

 Group B. Anthorhynchinse (Labbe). — The spores are ovoid 

 and have pointed ends. They are joined in strings. 

 The opening is equatorial. Typical genus, Anthorhyn- 

 chus Labbe, 1899. 

 Group C. Pileoeephalinse (Labbe). — The epimerite is simple 

 and regular; the spores are usually biconical. The 

 cysts open by simple rupture. Typical genus, Pileoce- 

 phalus A. Schneider, 1875. 

 Group D. Stictosporinae (Labbe). — The spores are biconical, 

 with the points slightly incurved. The endospore bears 

 papillje. Typical genus, Stictospora Leger, 1893. 

 Group E. Actlnocephalinas (Labbe). — The epimerite always 

 bears appendages. The spores are regular, cylindrical, 

 biconical, navicular, or subnavicular. Typical genus, 

 Schneideria Leger, 1892. 

 Family Acanthosporidae (Leger). — The epimerite may be sim- 

 ple or may bear appendages. The sporonts are always 

 solitary. The spores bear bristles at the equator or at 

 the poles. The cysts open by simple rupture. Found 

 parasitic in carnivorous insects. Typical genus, Corycella 

 Leger, 1892. 

 Family Menosporidas (Leger).- — ^The epimerite is symmetrical, 

 bears appendages, and is connected with the protomerite 

 by a long neck. The sporonts are solitary. The spores 

 are in the form of more or less curved crescents. The 

 spherical cysts open by simple rupture. Typical genus, 

 Menospora Leger, 1892. 

 Family Stylorhynchidae (A. Schn.). — Brown- or black-colored 

 spores occurring in strings. The epimerite is symmetrical 

 with or without appendages. The cyst has two envelopes 

 and contains a pseudocyst. Typical genus, Stylorhynchus 

 Stein, 1848. 

 Family Doliocystidae (Labbe). — Septum lacking. The epimerite 

 is regular and simple. The oval spores have a polar 

 thickening. Found parasitic in marine annelida. Typical 

 genus, Doliocystis Leger, 1893. 

 Order Coccidiida. — This order includes a large number of Sporozoa 

 that are cytozoic and karyozoic. The life cycles include an al- 

 ternation of generations in which a succession of schizogonous 

 cycles gives way to sporogony. Following syngamy, the oosphere 

 gives rise to sporoblasts, which may or may not be covered by a 

 sporocyst membrane and which may develop one or several sporo-
