Rule 12c. Sect. 3. Publication of Names 



RULE 12c. A name (1) which is not accepted by the author who published 

 it, or (2) which is merely proposed in anticipation of the future acceptance 

 of the taxon concerned, or of a particular circumscription, position or rank 

 of the taxon, or (3) which is merely mentioned incidentally is not validly 

 published. 



NOTE. Number (1) above does not apply to names or epithets published 

 with a question mark or other indication of taxonomic doubt, yet published 

 and accepted by the author. By "incidental mention" of a new name or 

 combination is meant mention by an author who does not intend to intro- 

 duce the new name or combination concerned. 



ANNOTATIONS 



Rule 12c (1). Beijerinck {Arch, neerl. d. sc. exactes, 1903, Sec. 2. 

 S:2\l) mentioned in a footnote to the publication in which he named 

 the genus Azotobacter that Parachromatium might be preferable to 

 show relationship to the genus Chromatium. It was not later used 

 by the author and may be regarded as not validly published. 



De Petschenko {Zentr. f. Bakt. Abt. 1. Orig. 55:90-92. 1910) de- 

 scribed a parasitic infection of a protozoan by a spiral organism. In 

 a footnote he suggested the generic name Muellerina with the species 

 M. paramecii. Later {Arch. Protist. 22:248-298. 1911) he published 

 a much more detailed description, repudiated his previously sug- 

 gested names, and proposed the new names Drepanospira and D. 

 muelleri. These latter, rather than the former, have been accepted 

 by action of the Judicial Commission as validly published. 



However, the author of a validly published name of a taxon may 

 not later change the name except to bring it into conformity with 

 the rules. 



The Zoological Rules state that when a name is given it is pre- 

 sumed to be published for use in zoological nomenclature. However, 

 if the author of the name makes clear that the name is not intended 

 tor such use, it has no status either for priority or for homonymy.
