GENERAL SYSTEMATIC BACTERIOLOGY 123 



classic Greek or Latin; and all terms improperly constructed should be 

 corrected. He further states that anagrams and geographic names 

 should be regarded as invalid for genera. 



Below under the heading of ''Recommendations" there are many- 

 suggestions of the best form to follow in the creation of generic names, 

 but failure to follow such recommendations does not render a term 

 invalid. 



Article 25. Subgenera and sections also receive names, usuallj' substantives 

 and resembling the names of genera. Names of subsections and other lower sub- 

 divisions of genera are preferably adjectives in the plural number and written 

 with a capital letter, or their place may be taken by an ordinal number or a letter. 



Examples: Substantives: Fraxinaster, Trifoliastrum, Adenoscilla, Euher- 

 mannia, Archieracium, Micromelilotiis, Pseudinga, Heterodraba, Gymnocimum, 

 Neoplantago, Stachyotypus. Adjectives: Pleiostylae, Fimbriati, Bibracteolata, 

 Pachycladae. 



Comments. Among names that have been applied to subgenera of 

 bacteria are Eusarcina and Euspirillum. 



Recommendations. IV. When the name of a genus, subgenus or section is 

 taken from the name of a person, it is formed in the following manner: 



a. When the name ends in a vowel, the letter a is added (for example Glazioua 

 Gtaziou; Bureaua after Bureau), except when the name already ends in a, in 

 which case ea is added (e.g., Collaea after Colla). 



b. When the name ends in a consonant, the letters ia are added (thus Mag- 

 nusia after Magnus; Ramondia after Ramond), except when the name ends 

 in er, in which case a is added (e.g., Kernera after Kerner). 



c. The spelling of the syllables unaffected by these finals is retained, even 

 with the consonants k and w or with groupings of vowels which were not used in 

 classic Latin. Letters which are unknown to botanical Latin must be transcribed, 

 diacritic signs are suppressed. The German a, 6, li, become ae, oe, ue, the French, 

 6, e and e become generally e. 



d. Names may be accompanied by a prefix, or a suffix, or modified by anagram 

 or abbreviation. In these cases they count as different words from the original 

 name. E.g., Durvillea and Urvillea, Lapeyroxisea and Peyrousea, Englera, 

 Englerastrum and Englerella, Bouchea and Ubochea, Gerardia and Graderia, 

 Martia and Martiusia. 



Comments. Among the generic names of bacteria which have been 

 derived from patronymics are Pasteurella, Salmonella, Klebsiella, Detoni- 

 ella, Zopfiella, Mantegazzaea, Erwinia, Pacinia, Cornelia, Newskia, 

 Pollendera, Macintoshillus, Metchnikovillus, ZopfiuSi It will be noted 

 that authors have frequently given generic names among the bacteria 

 by adding -ella in accordance with above. The custom is so well estab- 

 lished that there would seem to be little good reason at the present time
