alibus membranaceogelatinosis {capsulis) involuti." The following sub- 

 tribes are included: Euklebsielleae (genera Winogradskya, Klebsiella 

 and Dicoccia) and Mijconosioceae (genus Myconostoc). 



Klebsiellee. A variant of Klebsielleae used by Trevisan (1889, p. 

 25) with the description "Baculi, filamentie cocchi racchiusi in cap- 

 sule membranaceo-gelatinose." It constituted the second tribe of 

 Baculogene and contained the three genera Klebsiella, Dicoccia and 

 Myconostoc. 



Kokkaceen. An aberrant spelling of the family Coccaceae used by 

 certain German writers (as Hueppe 1886, p. 140). 



Kokken. Baumgarten (1890, p. 127) states: "1. Gatt. Kokken, 

 Bacterien arten umfassen d. welche nur kugehge Vegetationsformen 

 bilden." 



Usually used as a casual designation in German. 



Kokkobacillus. A generic name used by Biedert (1885, p. 439) 

 for the species K. zymogenus. It is to be regarded as a variant of 

 Coccobacillus (q.v.). Kokkobacillus avicidus is listed by Eisenberg 

 (1891, p. 275) as a synonym of Bacillus cholerae gallinarum. 



Kokkobacteria. A variant spelling of Coccobacteria used by lOebs 

 (1887, p. 50). 



Kokkobacterium. A variant spelling of Coccobacterium, q.v. The 

 name Kokkobacterium Lyssae is used in a review of an article by Rivolta 

 in Deutsche, med. Wochenschr. (1886, p. 313). 



Kokkothrix. A German variant of Coccothrix (Unna 1887, p. 29). 



Kokkus. A spelling of Coccus or coccus used by certain German 

 authors. For discussion see Coccus. 



Kurthia. A genus established by Trevisan (1885, p. 92) to include 

 Kurthia zopfii, the Bacterium zopfii of Kurth. The original descrip- 

 tion follows: 



Tre stadi di sviluppo vegetative: 1. Filamenti. 2. Bacilli. 3. Cocchi. 

 Filamenti (stadio protoplastico tipico) cilindrici, dapprima apparentemente 

 inarticolati, dappoi articolati, diritii, uniformi, agglomerati in colonie irrego- 

 larmente arrotondate. Cocchi (stadio finale dapprima appaiati, indi liberi. 

 Spore nulle od ignote. Specie unica. Kurthia Zopfii. 



It is noted as the fifth genus of Leptotrichiee by Trevisan (1889, p. 

 11) with the description "Vagine nulle." 



Later the organism named Bad. Laininariae of Billet was included. 

 The generic diagnosis as given by De Toni and Trevisan (1889, p. 931) 

 is as follows:
