Free-living Spironemacese.* — .1. Gross describes Saprospira g. 11., 

 with two species S. grandis and 8. nana. In Saprospira there is a 

 spirally coiled body and the multiplication is by fragmentation. He 

 regards Saprospira as a free-living genus of Spironemacese, and refers 

 the whole family to the Bacteria. 



Large Gregarine in Atyephyra.f — L. Mercier reports Cephaloidophora 

 cuenoti sp. n., a large Polycystid Gregarine, from the intestine of the 

 freshwater crustacean Atyephyra desmar<>sti Millet. It seems different 

 from Didymophyes longissima, which infests Gammarus and Orchestia. 

 Farther investigation is necessary, however, especially in the light of the 

 suggestion made by Leger and Duboscq that Cephaloidophora and 

 Porospora may represent respectively the gamogonous and schizogonous 

 phases of the same cycle. 



Haplosporidian Parasite in Donax.f — Casimir Cepede discusses the 

 life-history and affinities of the Haplosporidian which Caullery and 

 Chapellier described from the Trematode sporocysts of Donax and name 

 Anurosporidium pelseneeri. Its developmental cycle presents close 

 affinities with that of Cnidosporidians on the one hand and that of 

 Chytridiopsis on the other. It is nearly allied to Haplosporidium and 

 Urosporidium.
