GENERAL SYSTEMATIC BACTERIOLOGY 209 



Bacteriales. An ordinal name suggested by Clements (1909, p. 8). 

 His description is as follows: "Globose, rod-like or filamentous, single 

 or in colonies, sometimes grouped into a loose mass (zoogloea), but never 

 forming pseudoplasmodia or sporangium-like masses." He recognized 

 five famiKes, Beggiatoaceae, Chlamydobacteriaceae, Spirillaceae, Bac- 

 teriaceae and Coccaceae. 



Bacteridia. The Anglicized equivalent of Davaines casual name 

 bacteridie for the anthrax organism. 



Bacteridie. A casual name given by Davaine (1863, p. 195) for the 

 anthrax bacillus. Used for Bacteridium q.v. 



Bacteridieae. The fifth tribe of the family Bacillaceae as described 

 by Castellani and Chalmers (1919, p. 932). One genus only, Bacterid- 

 ium Schroeter, is included. The tribal designation is, 



Bacillaceae growing well on ordinary laboratory media, without endospores, 

 and either fluorescent or chromogenic. 



Type Genus. Bacteridium Schroeter, 1872. 



Bacteridium. A genus proposed by Davaine (1868, p. 21) to include 

 organisms with filiform bodies, more or less distinctly articulated in 

 consequence of imperfect division, always non-motile. The name was 

 created to provide for the anthrax bacillus. He states, 



III Genre Bacteridie. Bacteridium (Davaine). Corps filiforme, droit ou in- 

 flechi, plus ou moins distinctement articule, par suite d'une division spontanea 

 »»parfaite, toujours immobile. 



Apparently in this article at least he did not give a species name. He 

 writes "Bacteridie Charbonneuse (Davaine)" for the anthrax bacillus. 

 The latin generic name is definite enough, as is also the species con- 

 sidered. The casual designation bacteridies was first proposed in 1863 

 (p. 195), in the following statement: 



On voit, d'apres les considerations qui precedent, que le nom de bact^rie, par 

 lequel j'ai design^ primitivement ces corps, ne peut leur convenir. Lorsque 

 I'etude des etres microscopiques qui jouent un grand role dans la fermentation, 

 dans la putrefaction, etc., est a peine commencee, il serait pr^matur^ de vouloir 

 classer d'une maniere definitive les corpuscules du sang de rate, qui ont avec ces 

 €tres une analogie ^vidente. Je me bornerai done, pour designer ces corpuscules, 

 h, modifier l^gerement le nom que je leur ai primitivement donn6, et je les appel- 

 lerai d6soHBais des bacteridies. 



It is apparent that we have the anomalous situation of a suitable 

 generic name, Bacteridium, being published, together with an adequate
