Gregarina frantziusiana Diesing : 



Proboscis globosa, uncinulorum, octo coronula tenninali simplici (octolobia Frantzius). 

 Corpus subellipticum turgidum .... 



Gregarina heerii Kolliker. 



Proboscis antrorsum obovato-lanceolata, granulis exasperata, retrorsum subelliptica laevis, 

 inermis? .... Corpus longe ovatum .... 



Hab. Phryganea grandis larva, intestine, in both. 



From then on the present species is lost in the species Pileocephalus 

 heerii. It is obvious from a comparison of the epimerites that two very- 

 different species have been confused and that the original designation of 

 Frantzius still holds. ^ 



ACTINOCEPHALUS BRACHYDACTYLUS Ellis 

 [Figures 44 and 45] 



1913 AcHnocephalus brackydactylus Ellis 1913: 279, 289 



Sporonts solitary, elongate-ovoidal. Length 501/i, Ratio LP: :1 :3 to 4; 

 WP:WD: :1:1. Protomerite well-rounded, with same width as height, 

 slight constriction at septum. Deutomerite slightly wider at shoulder, 

 tapering gently and ending in a blunt point. Epimerite very short, a 

 corona of eight short digitiform processes. 



Cyst and spores unknown. 



Habitat not given. Host: Nymphs of Aeschna sp. 



Taken at Douglas Lake, Michigan. 



Genus GENEIORHYNCHUS Schneider 1875: 594 



Epimerite a tuft of short bristles set at the apex of a long slender neck. 

 Spores cylindro-biconical.

Sporonts solitary, obese, ovoidal. No dimensions given. Ratio 

 LP:TL: :1:4; WP:WD: :1:1.3. Protomerite very broadly rounded, 

 acuminate at apex. Slight constriction at septum. Deutomerite widest
