RULES OF NOMENCLATURE 63 



In the Manual all species names are written with a small letter. It is 

 felt that the value of a name as a name is lessened if capitals or other marks 

 are used to indicate etymology. The derivation of generic and specific 

 names is given separately in the descriptive material. 



Likewise for obvious reasons, microbiologists refused (Jour. Bact., 33, 

 1937, 445) to follow the botanical and zoological practice which permits the 

 use of duplicate generic names, one for an animal and the other for a plant 

 group ; and accepted the following rules to govern their practice. 



"a. Generic homonyms are not permitted in the group Protista, 

 h. It is advisable to avoid homonyms amongst Protista on the one hand, a plant 

 or animal on the other." 



The following actions of the International Committee on Bacteriological 

 Nomenclature (Cent. f. Bact., II Abt., 9£, 1935, 481) were confirmed 

 (Jour. Bact., 33, 1937, 445). 



Bacillus Cohn 1872 was accepted as a genus conservandum with Bacillus 

 subtilis Cohn emend. Prazmowski 1880 as type species. It was agreed 

 that Bacillus should be defined so as to exclude bacterial species which do 

 not form endospores ; and that the so-called Marburg strain found in type 

 culture collections should be accepted as the type or standard strain. 



At the Third International Congress of Microbiology held in New York 

 City in September, 1939, a series of recommendations of the Permanent 

 International Committees on Bacteriological Nomenclature were accepted 

 at the plenary session of the Congress. The third and fourth recommenda- 

 tions were: 



3. That the Nomenclature Committee, as at present constituted, shall continue 

 to function under the auspices of the International Association of Microbiologists 

 as it did under the International Society for Microbiology. 



4. That the International Committee shall select from its membership a Ju- 

 dicial Commission consisting of twelve member's, exclusive of members ex officio, 

 and shall designate a Chairman from the membership of the Commission. The 

 two Permanent Secretaries of the International Committee on Bacteriological 

 Nomenclature shall be members ex officio of the Judicial Commission. The Com- 

 missioners shall serve in three classes of four commissioners each for nine years, 

 so that one class of four commissioners shall retire at every International Con- 

 gress. In case of the resignation or death of any Commissioner, his place shall 

 be filled for the unexpired term by the International Committee at its next 

 meeting. 



By prompt action at and subsequent to the Congress ballots were cast 

 in spite of war conditions by 26 of the 62 members of the Permanent Com- 

 mittee on Nomenclature. These ballots when examined by the joint Secre- 

 taries of the Permanent Committee in November, 1942 were found to have 

 resulted in the selection of the persons whose names appear below. These
