Recommendation 24a. Sect. 6. Rejection and Replacement of Names 



RECOMMENDATION 24a. Authors should avoid introducing into bacteriology 

 as generic names such names as are in use in zoology. 



ANNOTATIONS 



Recoynmendaiton 24a. The author of a new generic name in bacteri- 

 ology should make sure that a name he wishes to propose is not a 

 later homonym of another generic name in bacteriology, in botany 

 or in protozoology. He is concerned only with names that have been 

 validly published; others have no nomenclatural status. 



In bacteriology there exists no adequate list of validly published 

 generic and subgeneric names. Such a list is in preparation and 

 should be published as an appendix to future editions of the Bac- 

 teriological Code. The International Bureau for Plant Taxonomy 

 and Nomenclature is preparing a card catalogue of validly published 

 names of plant genera, including the bacteria. As this list is pre- 

 pared the bacterial names will be published in the International 

 Bulletin of Bacteriological Nomenclature and Taxonomy. Until this 

 list is available, most questions of availability can be answered by 

 reference to the indices of the Seventh Edition of Bergey's Manual 

 of Determinative Bacteriology and its companion volume, the Index 

 Bergeyana. In obscure or difficult cases and determinations, authors 

 may request assistance from the Judicial Commission and its Edi- 

 torial Board. 



A list of validly published names of plant genera is in prepara- 

 tion as noted above in the form of a card catalogue. Until this is 

 completed one should consult for generic names of flowering plants 

 and ferns the Index Kewensis with its numerous supplements. Ains- 

 worth and Bisby's Dictionary of the Fungi, Ed. 4, 1954, gives a 

 virtually complete list of the generic names of fungi pioposed up to 

 about 1953. The Index of Fungi (issued by the Commonwealth 

 Mycological Institute, Kew) lists generic names published since. 



Becker prepared a list of generic names of protozoa taken from 

 the list of generic names of the Animal Kingdom (Schulze and 

 Kiickenthal, Neave) . The Zoological Record, with its carefully pre- 

 pared lists of names of taxa proposed in zoology, is probably the best 

 reference source in this field. 



Botanical Code. The Rules of the Bacteriological Code relative 

 to rejection of names and epithets do not differ materially from those 

 of the Botanical Code on which they were originally based.
