310 GENERAL SYSTEMATIC BACTERIOLOGY 



the first subtribe of the tribe Bacterieae, and contains the genera 

 Micrococcus and Bacterium. 



Heller (1921, p. 449) has proposed Eubacierieae as a class name 

 coordinate with Myxohacterieae in the phylum Bacteria. This spelling 

 is not in correct form for a class name. 



Eubeggiatoa. The first section of the genus Beggiatoa recognized 

 by Hansgirg (1888, p. 263). He gives the following description: 

 "Faden farblos, zu kreideweissen bis graugelblichen schleimigen 

 Massen vereinigt." Two species are listed, Beggiatoa alba (Vauch) 

 Trev. and B. arachnoideae (Ag.) Rbh. var. uncinata Hansg. 



Eucoccaceae. The second subfamily of the family Mycococcaceae 

 described by Hansgirg (1888, p. 267) with the following description: 

 "Zellen oder Zellfamilien ohne bestimmt begrenzte, Gallerthiillen, 

 nackt oder von einer gemeinsamen Gallerte umgeben." One genus 

 only, Micrococcus, is included. 



Eucoccus. A subgenus of the genus Micrococcus Cohn created by 

 Migula (1895, p. 16) to include those forms in which the cell contents 

 are colorless and free from sulphur granules. The second section is 

 Thiopolycoccus Winogradsky. 



Eu-Comilia. A subgenus of the genus Cornilia Trevisan established 

 by De Toni and Trevisan (1889, p. 998) to include those species which 

 are saprogenic and anaerobic. A variant of Eucornilia. 



Eucornilia. The name applied by Trevisan (1889, p. 21) to the first 

 subgenus of Cornilia. The second subgenus is Pleurospora. Altogether 

 twelve species are listed, of which the first is Cornilia alvei Trev. 



Eucrenothrix. A section of the genus Crenothrix suggested by 

 Hansgirg (1891, p. 314) to include the fresh water forms of the genus 

 with C. Kuhniana as the type. The other section for marine forms 

 he terms Phragmidiothrix. 



Eu-Klebsielleae. A subtribe of the tribe Klebsielleae created by 

 De Toni and Trevisan (1889, p. 1028) with the following diagnosis: 

 "Baculi recti vel curvi, numquam spiraHter torti." It contains three 

 genera: Winogradsky a Trevisan, Klebsiella Trevisan, Dicocda Trevisan. 



Eumantegazzaea. A subgenus of the genus Mantegazzaea created 

 by De Toni and Trevisan (1889, p. 942) to include three species which 

 are colorless and do not contain granules of sulfur. 



Eumicrospira. The name applied by Meyer (1912, p. 4) to the 

 second section of the genus Microspira. He included in the section 

 Rhodospira "Bakteriopurpurin enthaltende Species" and in Eumicro- 

 spira "AUe anderen Species."
