ends, 0.5 by 3 to 6 microns (Fiveiskaja, 

 loc. cit.). 



The following species have been placed 

 in genera belonging in the orders Chlamy- 

 dobacteriales and Eubacteriales respec- 

 tively : 



Cladothrix pelomyxae Vele3^ (Veley, 

 Jour. Linn. Soc, Zool., 39, 1905, 375; 

 see also Leiner, Arch. f. Protistenk., 4^', 

 1924, 282; Kirby, in Calkins and Sum- 

 mers, Protozoa in Biological Research, 

 New York, 1941, 1025; Hollande, Bull. 

 Biol. France Belg., 79, 1945, 49.) In the 

 cytoplasm of the rhizopod, Peloinyxa 

 palustris and probably also other species 

 of Pelomyxa. 



Rods, 1.5 to 22 microns or more in 

 length, divided into several to many 

 sections by transverse partitions, gen- 

 erally aggregated in proximity to the 



nuclei, which may be thickly invested by 

 close-set bacteria applied to the surface. 



Micrococcus batrochorum (sic) Yaki- 

 nioff. (Arch. f. Protistenk., 7£, 1930, 

 137.) In the cytoplasm of the flagellate, 

 Trichomonas bairachorum from the tree 

 toad {Hyla arborea) . Also seen free in 

 preparations of the intestinal contents 

 of Hyla. 



Round, 1 to 1.5 microns in diameter, 

 grouped generally in aggregates of ir- 

 regular form, but also occur individually.
