124 International Code of Nomenclature 



Provision 3. Provision 4. 



PROVISION 3 



Lists of nomina rejicienda. To avoid unnecessary confusion in 

 the nomenclature of bacteria by the strict application of the rules of 

 nomenclature, the Rules provide a list of names (nomina rejicienda) 

 which are not to be used, i.e., are to be permanently rejected. This 

 list includes names which, owing to segregation, are used with dif- 

 ferent meanings and have become a permanent source of confusion 

 or error (no77iina nmbigiia) , names where application is uncertain 

 (jiomina dubia) , and names applied to a group made up of two or 

 more discordant elements, especially if these elements were errone- 

 ously supposed to form part of the same individual (fiorniua con- 

 fiisa) . 



Note 1. This list of rejected names will remain permanently open 

 for additions. Any proposal of an additional name must be accom- 

 panied by a detailed statement of the case for and against its re- 

 jection. Such proposals must be submitted to the Judicial Commis- 

 sion of the Nomenclature Committee for study and appropriate ac- 

 tion. When a name proposed for rejection has been provisionally 

 rejected by the Judicial Commission, bacteriologists are authorized to 

 reject it pending the decision of the next International Congiess for 

 Microbiology. 



Note 2. A rejected name may not be later introduced legitimately 

 into bacteriological literature, except that nomina dubia may be re- 

 moved from the list upon submission of evidence of correct status and 

 by action by the Judicial Commission. 



PROVISION 4 



Permanent Interyiational Committee on Bacteriological Nomen- 

 clature. A Permanent International Committee on Bacteriological 

 Nomenclature has been established by the International Association 

 of Microbiological Societies in Congress. This Committee is so consti- 

 tuted that wherever practicable each country is represented by at 

 least one member and no country by more than five. Nominations 

 for membership are made preferably by one or more of the micro- 

 biological societies in each country. If nominations are not made by 

 the microbiological societies of a country, nominations may be made 

 by members of the Nomenclature Committee. Nominations should 

 be made in writing to one of the Permanent Secretaries of the Com- 

 mittee. Acceptance will be indicated by the Secretaries, and the 

 nominees given temporary membership in the Committee pending 

 action of the Committee and of the next International Congress, 

 when the election will be confirmed. 



The several societies and Committee members making nomina- 

 tions are urged to nominate persons representing all branches of
