at septum. Deutomerite cylindrical, tapering very slightly and ending in 

 a broad flattened extremity. Endocyte of deutomerite brown, rather 

 dense. Nucleus ellipsoidal, twice as long as wide, containing one or more 

 karyosomes. Mj^ocyte apparent. Cysts not described. Spores ellipsoi- 

 dal, with a thick integument. 



Taken at Poitiers, France. Host : Glomeris sp. Habitat : Intestine. 



There is but one species in this genus. Crawley (1903a :638-9) de- 

 scribed a species as Cnemidospora spirotoli but it has been removed to 

 the genus Stenophora, because it has none of the characters of the pres- 

 ent genus.

Amphoroides : Sporonts solitary, ovoidal, rather short and broad. 

 Length 170 - 200/^. Width not given. Ratio length protomerite : total 

 length : : 1 : 20 ; width protomerite : width deutomerite : : 1 : 26. Pro- 

 tomerite very short, depressed and cup-shaped within. Three times as 

 broad as high. Widest at top, where it is wider than the deutomerite 

 just below septum. A constriction at septum. Septum pushed up in 

 the middle to form a dome which is higher at its summit than the proto- 

 merite itself, the latter appearing as a crenulate collar about it. The 

 deutomerite is cylindrical through the anterior third, widening appre- 

 ciably to form a shoulder, below which it gradually tapers, ending in a 

 broad flattened extremity of approximately the same width as the ante- 

 rior third of the deutomerite. The endocyte is yellow-brown, the nu- 

 cleus spherical, its diameter as great as the width of the base of the deu- 

 tomerite and contains one large karyosome. The epimerite is a cylindro- 

 conical or globular papilla. Cysts are spherical, 150fx in average di- 

 ameter, dehisce by simple rupture and the spores are biconical, 7.8 by 3.8/a. 



Taken in the valleys of the Vienne and the Loire, France, and at 

 Vizzanova and Corte, Corsica. Hosts: Polydesmus complanatus (L.) ; 

 Polydesmus dispar Silvestri. Habitat: Intestine. 



This species was first described by Leger as Amphorella polydesmi. 

 The generic name was preoccupied and Labbe changed the name to Am- 

 phoroides. At the same time Labbe included with A. polydesmi as a 

 synonym Gregarina polydesmivirginiensis of Leidy, probably because 

 of the identity of the generic name of the hosts. The character of the
