Genus Nina Grebnecki. Protomerite formed of two long 

 narrow horizontal lobes fused and upturned spirally at one end. 

 Periphery shows many teeth, from which project long slender 

 filaments. The spores are in chain form. In the intestine of 

 myriapods. 



Nina gracilis Grebnecki. In the gut of Scolopendra cin- 

 gulata. 



Genus Asterophora Leger. Epimerite a thick horizontal disc 

 with a milled border and a stout style projecting from the 

 center. The spore cylindro-biconical. In Neuroptera and 

 Coleoptera. 



Asterophora philica (Leidy) (Fig. 125, /). In the gut of the 

 coleopteran, Nyctohates pennsylvanica. 



Genus Amphoroides Labbe. Epimerite a globular sessile 

 papilla. Protomerite cup-shaped. The spore is curved. In 

 myriapods. 



Amphoroides calverti (Crawley) (Fig. 125, m). In the gut of 

 Callipus and Lysiopetalum. 



Genus Steinina Leger and Duboscq. Solitary. Epimerite a 

 short motile digitform process changing into a flattened struc- 

 ture. The spore is biconical. In Coleoptera. 



Steinina rotunda Watson (Fig. 125, w). In the gut of Amara 

 augustata. 



Genus Stylocephalus Ellis. Solitary. Epimerite a dilated 

 papilla at the end of a long process. The cyst covered with small 

 papillae and indentations. The spore is hat-shaped. In various 

 arthropods and molluscs. 



Stylocephalus giganteus Ellis (Fig. 125, o). In the gut of co- 

 leopteran insects belonging to the genera Eleodes, Eusattus, 

 and Asida. 



Genus Porospora Schneider. The schizogony takes place in 

 a crustacean and sporogony occurs in a molluscan host. The 

 development is peculiar. The mature spore contains a single 

 vermiform sporozoite which becomes attached to the gut- 

 epithelium of the crab. It develops into a very long trophozoite. 

 One, two, or sometimes three of them unite and encyst together. 

 The nucleus divides repeatedly and finally a number of "gymno- 

 spores" are formed. Certain authors hold this change as asexual, 

 or schizogonic, reproduction, and hence include the genus in the
