306 GENERAL SYSTEMATIC BACTERIOLOGY 



Escherichia. A name given to the tenth genus of the tribe Eber- 

 theae by Castellani and Chahners (1919, p. 935). The description 

 (p. 941) foUows: 



Ebertheae which ferment glucose and lactose completely; milk clotted. 

 Type Species. Escherichia coli (Escherich, 1886). 



Some 16 species (1920, p. 619) are listed. 



Bergey et al. (1923, p. 194) includes Escherichia as the first genus of 

 the tribe Bactereae with the following description: 



Motile or non-motile rods, commonly occurring in the intestinal canal of nor- 

 mal animals. Attack numerous carbohydrates forming acid and frequently acid 

 and gas. Do not produce acetyl-methyl-carbinol. 



The type species is Escherichia coli (Escherich) Castellani and Chalmers. 



Eu-Ascococceae. A name given by De Toni and Trevisan (1889, p. 

 1035) to a subtribe of the tribe Ascococceae, with the following diag- 

 nosis: "Subtribus I. Eu-Ascococceae: Cocci in muco matricali segre- 

 gati, in familias cystidibus universalibus obductas cumulati. Cystides 

 speciales nullae." It contains seven genera: Lamprocystis Schroter, 

 Ascococcus Cohn, Bollingera Trevisan, Leucocystis Schroter, Cenomesia 

 Trevisan, Thiothece Winogradsky, Thiocystis Winogradsky. 



This name does not appear to have been used by other investigators. 



Eubacilleae. The third subtribe of the tribe Bacilleae proposed 

 by De Toni and Trevisan (1889, p. 939) with the following diagnosis: 

 ''Baculi (divisione semper in unam directionem transversalem) liberi, 

 numquam spiraliter torti, Endosporae." Ten genera are noted: 

 Mantegazzea Trevisan, Bacillus Cohn, Pasteurella Trevisan, Cornilia 

 Trevisan, Clostridium Prazmowsky, Vibrio Zopf, Svirillum Ehren- 

 berg, Spiromonas Perty, Pacinid Trevisan, Bacterium Ehrenberg. 



Eubacillus. This name was first used by Hansgirg (1888, p. 264) 

 for the first section of the genus Bacillus with the following diagnosis: 

 "Zellen mit farblosen, feinkornigen Plasma, ohne grossere Schwefel- 

 kornchen, zu farblosen oder grau-bis gelblich-braunlichen Schleim- 

 massen (Zoogloeen) vereinigt." B. subtilis was included in this section. 



A genus of green bacteria proposed by Dangeard (1891, p. 151) 

 was also given this name. This genus was created to include those 

 organisms, rod-shaped in form, or variable length, with hyaline pro- 

 toplasm, containing no granules and with a small amount of chloro- 

 phyll in the protoplasm, spore bearing filament may be simple or 

 branched, the green color more pronounced in the swellings, spores
