272 GENERAL SYSTEMATIC BACTERIOLOGY 



Bacterium ureae and a Micrococcus ureae together with other unnamed 

 organisms. Cornil and Babes (1890, p. 153) in the third edition of 

 "Les Bacteries" figm-e a "Coccobacillus zymogene de Leube." The 

 figure is of two distinct organisms, No. 1 and No. 3 of Leube. Ap- 

 parently De Toni and Trevisan are in error in ascribing a Coccohacillus 

 zymogenes to Leube or to Cornil and Babes. Bergey et al. (1923, p. 

 265) state that Coccohacillus avicidus was used by Perroncito (1879, 

 p. 22). A careful examination of the original shows no such use. 



This name was also introduced independently by Gamaleia (1888, 

 p. 167) in the name Coccohacillus avicidus used for the organisms which 

 caused bird septicemia (including fowl cholera). The name in this 

 sense, however, is a synonym of the earlier name, Pasteurella Trevisan, 

 which has priority. 



Tissier (1900, p. 70) described a Cocco-Bacillus anaerohius perfoetans 

 from infant diarrhea. 



Tissier (1905, p. 114) notes a Coccohacillus perfoetans from the in- 

 testines. This organism is of two varieties, one which ferments glu- 

 cose and saccharose, the other glucose, saccharose and lactose. In- 

 active lactic acid is produced, and small quantities of butyric and 

 valerianic acids. Does not form indol. This generic name is re- 

 jected by Erwin F. Smith (1905, p. 174). 



The name has also been used as a casual designation of the conjuncti- 

 val organisms commonly known as diplobacilU. This is the use made 

 by Ruata (1909, p. 630) who designates the organism as Coccohacillus 

 conjunctivae. A species, Coccohacillus fusiformis has also been named 

 by Karwacki (1909, p. 679). 



Coccohacillus acridiorum in a name appHed by D'Herelle (1914, 

 p. 408) to an organism causing a disease in locusts. This is Gram- 

 negative motile bacillus, fermenting glucose, levulose, maltose and 

 galactose. It apparently belongs with the colon typhoid series of 

 bacteria. 



Cocco-Bacillus. A variant of Coccohacillus q.v. used by Tissier 

 (1899, p. 70) for the species Cocco-Bacillus anaerohius perfoetans. 

 As it was part of a trinomial, it may be regarded as invaHd. 



Coccobacteria. This generic name was introduced by Billroth 

 (1874, p. 1) for the species Coccohacteria sepfica. This author con- 

 ceived all bacteria to belong to one very pleomorphic species. He 

 describes it as a kind of plant which consists partly of spherical and 

 partly of rod-shaped cells which may show considerable variation in 

 size. Each form may change into the other, although there is a certain
