GENERAL SYSTEMATIC BACTTERIOLOGY 233 



single polar flagellum. Four genera are included, Bacirinium, Plectri- 

 nium, Clostrinium and Arihrohactrinium. This name is not in correct 

 form. 



Bactrinium. A genus of bacteria proposed by Fischer (1895, p. 41). 

 This genus is one of four belonging to the subfamily Bactriniei. The 

 organisms belonging to this genus are rod-shaped and motile by means 

 of a single polar jflagellum. Spores are produced without any altera- 

 tion in the shape of the mother cell. 



Bactrinium nov. gen. Beweglich, mit polarer Einzelgeissel und Endosporen in 

 nicht aufgeschwoUenen Stabchen. Eine eingeisselige Form mit Endosporen ist 

 noch nicht ausfiihrlich beschrieben dagegen kann mit grosser Wahrscheinlichkeit 

 der Bacillus pijocyaneus, der nach Loffler eine Geissel tragt, hierher gestellt 

 werden; ebenso der von Loffler abgebildete grosse Bacillus aus einem Pflanzenauf- 

 guss. Ich selbst habe bis jetzt keine solche Forme gefunden. Auch die von 

 Winogradsky beschriebenen Xitritbakterien von Zurich und Buitenzorg konn- 

 ten hierher gehoren. 



Later the genus was defined (1897, p. 32) (1903, p. 60) as motile, 

 monotrichous with a terminal cilium and including provisionally all 

 monotrichous rods whose spores are as yet unknown, e.g., Bact. 

 pyocyaneum. 



This genus name has never come into common use. It is rejected 

 by Erwin F. Smith (1905). It is generally regarded as invalid, and a 

 synonjTn of Pseiidomonas Migula. Possibly Bactrinium pyocyaneum 

 (Loffler) Fischer may be regarded as the type. 



Bactrinius. A genus of bacteria proposed by Kendall (1902, p. 484) 

 to include those rod-shaped organisms motile bj^ means of a tuft of polar 

 flagella. This name has never come into common use and has probably 

 not been used for any species of bacteria. It may be regarded as invalid, 

 and a synonjon of Pseudomonas. 



Baculogenae. A subfamily of the family Schizomycetaceae proposed 

 byTrevisan (1885). 



The diagnosis of this subfamily as given by De Toni and Trevisan 

 (1889, p. 939) is as follows: 



Adsunt tres status evolutionis h. e. baculi, filamenta, cocci. Baculi (status 

 primarius, initialig seu archetj-pus) filamenta et coccos gignentes; filamenta 

 (status secundarius transitorius) nunquam vaginata, nee basi distincta praedita, 

 non affixa nee e puncto central! radiantia, e prolongatione idefinita singuli baculi 

 V. e. plurimorum baculorum conjunctione (ob divisionem imperfectam) effonnati. 



The subfamily is divided into the following tribes: Bacilleae (12 

 genera), Klebsielleae (4 genera). This designation of the subfamily
