Gregarina frantziusiana Diesing: 



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

 Corpus subellipticuin turgidum .... 



Gregarina heerii Kolliker. 



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

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



Hab. Pkryganea 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 stiU holds. 



ACTINOCEPHALUS BRACHYDACTYLUS EUis 

 [Figures 44 and 45] 



1913 Actinocephalus brachydactylus Ellis 1913: 279, 289 



Sporonts solitary, elongate-ovoidal. Length 501iu. 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 

 at mid-portion, ending in an acute point. Epimerite a tuft of short sharp 

 bristles set at apex of a long slender neck. Nucleus spherical with several 

 karyosomes. Cyst dehiscence by simple rupture, spores sub-navicular. 



Intestine of Libellules sp. 



Taken near Paris.
