einzufiihren. Einige franzosische Autoren haben daraufhin diese Nominiering 

 gewahlt, wiihrend Montfallet & Boschetti mit begriindeter Darlegung Stellung 

 dagegen nahmen. Auch Referentem scheint die Neubenennung unnotig und 

 willkiirlich, und der Name, welcher den Charakter der Krankheit ausdriickt, 

 passender. 



Winslow et al. (Committee Soc. Am. Bact., 1917, p. 561) accepted 

 the designation with the description : 



Short rods, single or rarely in chains, usually showing distinct polar staining. 

 Non-motile. Gram-negative. Without spores. Aerobic and facultative. Powers 

 of carbohydrate fermentation slight; no gas produced. Gelatin not liquefied. 

 Parasitic, frequently pathogenic, producing plague in man and hemorrhagic 

 septicemia in the lower animals. 



The type species is Pasteurella cholerae-gallinarum (Fliigge) Trevisan. 



Buchanan (1918, p. 52) used the following description: 



Short rods, single or rarely in chains, usually showing distinct polar staining, 

 non-motile. Gram-negative, without spores, aerobic and facultative, usually 

 not producing gas, powers of fermentation slight, often pathogenic, not acid-fast, 

 not liquefying gelatin. 



The type species is Pasteurella cholerae-gallinarum (Fluegge) Trevisan. 



The genus is made the type of the tribe Pasteurelleae by Castellani 

 and Chahners (1919, p. 943). Bergey (1923, p. 264) also includes the 

 genus in the tribe Pasteurelleae. 



The name of the type species is somewhat puzzling. Apparently 

 the first species name for the fowl cholera organism was Micrococcus 

 gallicidus Burrill (1883, p. 320). His description is inadequate, but 

 he claimed he was describing the cause of fowl cholera. Zopf (1885, 

 p. 87) called the organism Micrococcus cholerae-gallinarum and Trevisan 

 Pasteurella cholerae-gallinarum. It would appear the correct designa- 

 tion would either be Pasteurella cholerae-gallinarum (Zopf) Trevisan 

 or Pasteurella gallicida (Burrill) comb, no v. 



Pasteurelleae. A name proposed by Castellani and Chalmers 

 (1919, p. 932) for the eighth tribe of the family Bacillaceae. The de- 

 scription (1919, p. 943) is: 



Bacillaceae with good growth on ordinary media, without endospores, a§robic, 

 without fluorescence or pigment formation, unable to liquefy gelatine, and Gram- 

 negative, but with polar staining. 



Type genus. Pasteurella De Toni and Trevisan, 1889. 



Winslow et al. (Committee Soc. Am. Bact., 1920, p. 211) indepen- 

 dently proposed the same name with the following diagnosis: "Gram-
