298 GENERAL SYSTEMATIC BACTERIOLOGY 



formation, or gelatine liquefaction; without polar staining; Gram-negative, 

 without a capsule. 



Type Genus. Eberthus Castellani and Chalmers, 1918. 



Ten genera are included, Alcaligenes, Eberthus, Shigella, Dysen- 

 teroides, Lankoides, Salmonella, Balkanella, Wesenbergus, Enteroides 

 and Escherichia. 



Eberthella. A subgenus of Bacterium proposed by Buchanan (1918, 

 p. 53) to include those forms "Not producing gas from any of the 

 carbohydrates, acid may or may not be formed." The type species 

 is designated as Bacterium (Eberthella) typhi. Flligge. 



Bergey et al. (1923, p. 221) erected Eberthella into a genus, erron- 

 eously ascribing the name to Castellani and Chalmers. Possibly this 

 is a misprint for the generic name Eberthus used by Castellani and 

 Chalmers for the same group. It is included as the fifth genus of the 

 tribe Bactereae with the following description: 



Motile or non-motile rods, occurring in the intestinal canal of man, usually in 

 different forms of enteric inflammation. Attack a number of carbohydrates with 

 the formation of acid but no gas. Do not form acetyl-methyl-carbinol 



The type species is Eberthella typhi (Eberth-Gaffky) Castellani and Chalmers. 



Eberthus. The second genus of the tribe Ebertheae named by 

 Castellani and Chalmers (1919, p. 934). The description (p. 936) 

 follows : 



Bacillaceae motile, partially fermenting glucose with the production of acid 

 and no gas. Lactose not fermented. Milk not clotted. 

 Type Species. Eberthus typhosus (Zopf, 1885). 



Later (1920, p. 604) four species are described. 



Eccrina. A generic name proposed by Leidy (1851, p. 35) for an 

 entophyte with "Characters same as Enterobryus, except that it 

 divided into numerous cells at the free extremity." Two species were 

 described, Eccrina longa from the mucous membrane of the intestine 

 of Polydesmus virginiensis, and Eccrina moniliforma from Polydesmus 

 granulatus. 



Leidy (1851, p. 29) later described the genus as follows: 



Thallus attached, consisting of a single very long tubular cell, filled with granu- 

 les and globules, producing at its free extremity a succession of numerous globular 

 or oblong cells, and growing at the other end from a relatively short, cylin- 

 droid, amorphous coriaceous pedicle, commencing with a discoidal surface of 

 attachment.
