94 International Code of Nomenclature 



Recommendation 24a. Rejection and Replacement of Names 



One botanical rule not duplicated in the Bacteriological Code 

 relates to acceptance in botany of names of taxa transferred from the 

 animal to the plant kingdom. A name of a taxon is illegitimate if 

 it is the name of a taxon which at the time of such transfer becomes 

 a homonym of the name of an existing jjlant taxon. Names of taxa 

 transferred from the plant to the animal kingdom retain their botani- 

 cal nomenclatural status for purposes of homonymy. 



That there will be transfer of taxa to or from branches of zoology 

 other than protozoology to botany is improbable. 



Zoological Rules. A "Code of Ethics" which appeared in some 

 earlier editions of the Rules has been rephrased. A zoologist who 

 notes that a generic or specific name published by a living author as 

 new is a later homonym and therefore unavailable should notify the 

 author of the facts and give ample opportunity for a substitute name 

 to be proposed by him. 



When an organism is transferred from the animal to the vege- 

 table kingdom, its generic name for purposes of homonymy retains 

 its status under the Zoological Code.
