338 GENERAL SYSTEMATIC BACTERIOLOGY 



Filamenta cylindrica, vagina delicatissima evanescente obducta, simplicia, 

 utrinque apicibus conformia, primitus apparenter subcontinua, cito articulata, 

 articulis aetate provecta, vagina evanida, in baculos et coccos soluta. Multi- 

 plicatio baculis primitus vivide mobilibus, propere immotis. Arthrosporae trans- 

 formatione cocci singiili ortae. Obs. Arthrospore in parvulos acervos zoogloeicos 

 conglobantur in quibus nova filamenta radiatur exoriuntur. 



The genus is rejected by Erwin F. Smith (1905). 



Bo^t. zopfii Kurth may be regarded as the type. 



Apparently Wenner and Rettger were not aware of the use of Kurihia 

 with the species K. zopfii as the type, as this has priority over Zopfius 

 q.v. which has the same specific type. 



Kurthieae. A tribe created by De Toni and Trevisan (1889, p. 929) 

 with the following diagnosis: "Sporae (arthrosporae) in filamentis 

 normalibus obvenientes. Filamenta simplicia, basi ab apice superiori 

 ut plurimum distincta, vaginata vel evaginata." 



The following genera are included, Detoniella, Rasmussenia, and 

 Kurthia. 



Lactobacillaceae. A family named by Winslow et al. (Committee 

 Soc. Am. Bact., 1917, p. 561) with the following description: 



Rods, often long and slender, Gram-positive, non-motile, without endospores. 

 Usually produce acid from carbohydrates, as a rule lactic. When gas is formed, 

 it is CO2 without H2. The organisms are usually somewhat thermophilic. As a 

 rule microaerophilic ; surface growth on media poor. 



The genus Lactobacillus was included. 



Lactobacillae. A variant spelling of Lactobacilleae used by Bergey 

 et al. (1923, p. 241). It is included as the eighth tribe of the family 

 Bacteriaceae. The description follows: 



Rods, often long and slender. Gram-positive. Non-motile. Without endo- 

 spores. Usually produce acid from carbohydrates, as a rule lactic. When gas is 

 formed it is CO2 without H2. The organisms are usually somewhat thermophilic. 

 As a rule, microaerophilic. Surface growth on media is poor. 



Lactobacilleae. A tribe named by Winslow et al. (1920, p. 211). 



Rods, often long and slender. Gram-positive, non-motile, without endo- 

 spores. Usually produce acid from carbohydrates, as a rule lactic. When gas is 

 formed, it is CO2 without H2. The organisms are usually somewhat thermophilic. 

 As a rule microaerophilic; surface growth on media poor. 



It includes the genus Lactobacillus. 



Lactobacillus. A genus of bacteria proposed by Beijerinck (1901, 

 p. 214) to include all rod shaped forms "qui produisent I'acide actif
