GENERAL SYSTEMATIC BACTERIOLOGY 307 



formed by the contraction of the protoplasm of the swellings; spores 

 refringent, grouped or isolated, separated from each other by septa. 

 The genus is divided into two sections, the first containing the type 

 species, Eubacillus multisporus Dangeard. This organism is made 

 up of filaments which are simple, long, and slender and of a faint green 

 color. The spore bearing filaments are likewise quite long, producing 

 the numerous spores isolated or grouped in pairs, threes, fours, sepa- 

 rated by septa. Spores are elliptical in shape and of a decided green 

 color with one or two refringent granules. Length of spores: 5 to 8/x, 

 width: ZfjL. Habitat: Developing in cultures of algae from fresh 

 water. 



In the second section, the author includes five species of bacteria 

 which have been described by Kline, all of which are green in color. 



Lehmann and Neumann (1896, p. 11) question the ascription of this 

 genus to the bacteria. IVIigula (1897, p. 94) concludes that the or- 

 ganisms described under this name by Dangeard do not belong to the 

 bacteria, both because the spore bearing filaments of his Eubacillus 

 multisporus were branched at times and because of the formation of 

 spores in chains which is not characteristic of bacteria. 



Meyer (1912, p. 2) uses the name Eubacillus for the third section of 

 the genus Bacillus with the statement: "Enthalt alle iibrigen Spezies 

 der Gattung, auch die, fiir welche Sporangienbildung nicht gesehen 

 wurde." 



Doubt as to the generic validity of Eubacillus Dangeard is raised 

 by the previous use of the term by Hansgirg, in practically a subgeneric 

 sense. There is also some reasonable doubt as to whether Dangeard's 

 organism belongs with the bacteria. 



Eu-Bacillus. A subgenus of Bacillus proposed by Buchanan (1918, 

 p. 38). A variant of Eubacillus Hansgirg. The description follows: 



Motile, usually by means of peritrichous flagella. Spores not barrel-shaped 

 without longitudinal ridges. Other characters those of the genus. 

 The type species of the subgenus is Bacillus subtilis Cohn. 



Eubacteria. The fifth order of bacteria recognized by Schroter 

 (1886, p. 154) with the following diagnosis: 



Vegetative Zellen kiirzer oder langer stabchenformig, ruhend oder bewegt, 

 frei oder in Schleim eingebettet. Haufig wachsen sie in lange Faden aus, welch 

 aus einzelnen Gliedern bestehen, die bei der Sporenbildung wieder durch scharfere 

 Theilung deutlich werden; sie zeigen keine deutliche gemeinsame Scheiden. 

 Sporen meist einzeln innerhalb der Zellen gebildet und deren Raum nicht ganz
