1885 Clepsidrina Laucournetensis Schneider 1885a :28 



1899 Oregarina laucournetensis Labbe 1899:11 



Gregarina: Sporonts biassociative, obese. Length 60 to 70/t; width 

 50 - 60/x. Cysts spherical, one spore duct. Spores elongate ovoidal, ex- 

 truded in chains. 



Taken at ? Host: Parnus sp. Habitat: Intestine. 



GREGARINA STATIRAE Frenzel 



[Figure 138] 



1892 Gregarina statirae Frenzel 1892 :234-82 



Sporonts biassociative, spheroidal. Length 300 to 350/*. Width 

 200)11. Ratio length protomerite : total length primite :: 1 : 5; width 

 protomerite : width deutomerite :: 1 : 3.5. protomerite hemispheri- 

 cal, widest at base, 1.7 times as wide as high. Deutomerite spherical, as 

 wide as high. Nucleus spherical, with one karyosome. Endocyte 

 dense except in anterior third of protomerite, where it is sparse. Epi- 

 merite a simple short cylindrical papilla rounded at apex. 



Spores and cysts unknown. 



Taken at Cordoba, Argentina. Host: Statira unicolor Blanch. 

 Habitat : Intestine. 



GREGARINA LONGIROSTRIS (Leger) Labbe 



[Figure 155] 



1892 Clepsidrina longirostris Leger 1892:122-4 



1899 Gregarina longirostris Labbe 1899 :12 



Gregarina : Sporonts biassociative, obese. lOO/x. long. Ratio length 

 protomerite : total length : : 1 : 4 ; width protomerite : width deu- 

 tomerite : : 1 : 1.1. Protomerite conoidal, dilated in posterior half. 

 No constriction at septum, Protomerite obovoidal. Nucleus spherical 

 with one karyosome. Epimerite an elongate simple cylinder, 50 - 60/x 

 long, one half or more than half as long as whole cephalont. Endoplasm 

 greenish yellow. 



Cysts ovoidal, 60 to 70/* in diameter. One spore duct. Spores bar- 

 rel shaped, 7.4 by 3.8/t. 



Taken in the valley of the Loire, France. Host : Thanasimus formi- 

 carius (L.). Habitat: Intestine.
