142 GENERAL SYSTEMATIC BACTERIOLOGY 



Recommendations. The prefixes sub and pseudo should be used only with ad- 

 jectives and substantives, sub with Latin words, pseudo with Greek words, and 

 they should not be used in combination with proper names. Examples: sub- 

 viridis, subchelatus, Pseudacanthus, Pseudophis, Pseudomys. Words like sub- 

 wilsoni and pseudo-grateloupana are not recommended. 



The terminations oides and ides should be used in combination only with Greek 

 or Latin substantives ; they should not be used in combination with proper names. 



Geographic and patronymic names from countries which have no recognized 

 orthography or which do not use the Latin alphabet, should be transcribed into 

 Latin according to the rules adopted by the Geographic Society of Paris. (See 

 Appendix G.) 



In proposing new names based upon personal names, which are written some- 

 times with a, 6 or ii, at other times with ae, oe, and ue, it is recommended that 

 authors adopt ae, oe and ue. Example muelleri in preference to miilleri. 



Author's name. 



Article 21. The author of a scientific name is that person who first publishes 

 the name in connection with an indication, a definition, or a description, unless 

 it is clear from the contents of the publication that some other person is respon- 

 sible for said name and its indication, definition, or description. 



Article 22. If it is desired to cite the author's name, this should follow the 

 scientific name without interposition of any mark of punctuation; if other cita- 

 tions are desirable (date, sp. n., emend., sensu stricto, etc.) these follow after the 

 author's name, but are separated from it by a comma or by parenthesis. Exam- 

 ples: Primates Linn6, 1758, or Primates Linne (1758). 



Recommendation. When the name of the author of a scientific name is abbre- 

 viated, the writer will do well to conform to the list of abbreviations published 

 by the Zoological Museum of Berlin. 



Article 23. When a species is transferred to another than the original genus 

 or the specific name is combined with any other generic name than that with which 

 it was originally published, the name of the author of the specific name is retained 

 in the notation but placed in parentheses. Examples: Taenia lata Linn6, 1758, 

 and Dibothriocephalus latus (Linne, 1758); Fasciola hepatica Linn6, 1758, and 

 Distoma hepaticum (Linn6, 1758). 



If it is desired to cite the author of the new combination his name follows the 

 parentheses. Example: Limnatis niloiica (Savigny, 1820) Moquin-Tandon, 1826. 



Article 24. When a species is divided, the restricted species to which the 

 original specific name of the primitive species is attributed may receive a notation 

 indicating both the name of the original author and the name of the reviser. 

 Example: Taenia solium Linn6, partim, Goeze. 



The law of priority 



Article 25. The valid name of a genus or species can be only that name under 

 which it was first designated on the condition : 



a. That this name was published and accompanied by an indication, or a 

 definition, or a description; and 



b. That the author has applied the principles of binary nomenclature.
