ACNIDOSPORIDIA, SARCOSPORIDIA 513 



Genus Anurosporidium Caullery and Chappellier. Similar to 

 Haplosporidium, but operculate spore spherical. 



A. pelseneeri C. and C. In sporocyst of a trematode parasitic in 

 Donax trunculus; schizogony intracellular; cysts extracellular, with 

 up to 200 spores; spores about 5ai long. 



Genus Bertramia Caullery and Mesnil. Parasitic in aquatic worms 

 and rotifers; sausage-shaped bodies in coelom of host; spherical 

 spores which develop in them, possess a uninucleate sporoplasm and 

 a well-developed membrane. 



B. asperospora (Fritsch) (Fig. 242, j, k). In body cavity of rotifers: 

 Brachionus, Asplanchna, Synchaeta, Hydatina, etc.; fully grown 

 vermicular body 70-90m with 80-150 spores. 



B. capitellae C. and M. In the annelid Capitella capitata; spores 

 2.5m in diameter. 



B. euchlanis Konsuloff. In coelom of rotifers belonging to the 

 genus Euchlanis. 



Genus Ichthyosporidium Caullery and Mesnil. In fish; often 

 looked upon as Microsporidia, as the organism develops into large 

 bodies in body muscles, connective tissue, or gills, which appear as 

 conspicuous "cysts," that are surrounded by a thick wall and con- 

 tain numerous spores. 



I. giganteum (Thelohan) (Fig. 241). In various organs of Creni- 

 lahrus melops and C. ocellatus; cysts 30/x-2 mm. in diameter; spores 

 5-8m long. 



/, hertwigi Swarczewsky. In Crenilahrus paro; cysts 3-4 mm. in 

 diameter in gills; spores 6m long. 



Genus Coelosporidium Mesnil and Marchoux. In coelom of Cla- 

 docera or Malpighian tubules of cockroach; body small, forming 

 cysts; spores resemble microsporidian spores; but without a polar 

 filament. 



C. periplanetae (Lutz and Splendore) (C. hlatellae Crawley) (Fig. 

 242, I, m). In lumen of Malpighian tubules of cockroaches; common; 

 spores 5.5-7.5m by 3-4m.
