Some old names are displaced by new descriptive terms : Phaeospirillum 

 Sulfospirilluin, Desulfovibi'io, Phaeomonas, Aeromonas, Zymomonas, Me- 

 thanobacterium, Methanococcus, Meihanosarcina, Butyrisarcina, Peptococcus, 

 Peptostreplococcus, Zymobacillus. Rhodomonas is not used in the same sense 

 as Rhodomonas Orla-Jensen (Cent. f. Bakt., II Abt., £2, 1909, 331 and 334), 

 the latter being a synonym of Chromatium Perty (Zur Kenntniss kleinster 

 Lebensformen, 1852). Sulfomonas is indicated as new and as a synonym 

 of Thiobacillus Beijerinck (Cent. f. Bakt., II Abt., 11, 1904, 598) although 

 the same term is used by Orla-Jensen (loc. cit.). Three new terms are 

 accepted : C/i/oro6zMm Nadson (Bull. Jard. Bot. St. Petersburg, 6, 1906, 184), 

 Zymosarcina Smit (Die Garungssarcinen, Jena, 1930) and Peptoclostridium 

 CDonker, Inaug. Diss., Delft, 1926). 



Rahn (Cent. f. Bakt., II Abt., 96, 1937, 273) has reviewed the characters 

 of the species of Eubacteriales included in the fourth edition of this Manual. 

 He places 146 of the spore-forming species in a Sub-order A. Endosporales 

 with a single family, and 536 of the species of non-spore-forming rods in a 

 Sub-order B. Asporales in seven families. Unclassifiable species (total 224) 

 are placed in a temporary eighth family Bacteriaceae. His outline follows:
