The first outline classification drawn up by Janke (Allgemeine Technische 

 Mikrobiologie, I Teil, Dresden, 1924, p. 63) is an adaptation and expansion 

 of that drawn up by Migula (System der Bakterien, 1900) . The new genera 

 recognized by Janke are Planostre^tococcus A. Meyer (Die Zelle der Bak- 

 terien, Jena, 1912), Thioploca Lauterborn (Ber. dtsch. Bot. Gesell,, 25, 

 1907, 238), Thiohacterium Molisch (Cent. f. Bakt., II Abt., 33, 1912, 55), 

 Thiobacillus Beijerinck (Cent. f. Bakt., II Abt., 11, 1904, 593), Thiovihrio 

 Janke {loc. cit.), Thiospirillum Winogradsky (Beitrage zu Morphol. u. 

 Physiol, d. Bakterien. Heft I. Schwefelbakterien. Leipzig, 1888), Thio- 

 sphaerella Nadson (Bull. Jar. bot. Petersburg, 13, 1913, 106; ref. in Cent. 

 f. Bakt., II Abt., 43, 1915, 469), Thiovulum Hintze (Ber. Dtsch. Bot. 

 Gesell., 31, 1913, 189), Spirophyllum Ellis (Proc. Roy. Soc. Edinburgh, 27, 

 I, 1907, 21; ref. in Cent. f. Bakt., II Abt., 19, 1907, 502), Nodofolium Ellis 

 (Cent. f. Bakt., II Abt., 26, 1910, 321), and Actinococcus Beijerinck (Fol. 

 Microbiol.,:^, 1914, 185).
