![Upon unanimous recommendation by the International Commission on Zoological Nomenclature, the International Zoological Congress which met at Budapest, Hungary, September 4-9, 1927, adopted a very important amendment to Article 25 (Law of Priority) which makes this-Article, as amended, read as follows (the italic part represents the amendment ; the part not in italic represents the old wording) :— Article 25. The valid name of a genus or species can be only that name under which it was first designated on the condition— (a) That ('prior to January 1, 1931) this name was published and accompanied by an indication, or a definition, or a description ; and (h) That the author has applied the principles of binary nomenclature. (c) But no generic name or specific name published after December 31, 1930, shall have any status of availability (hence also, of validity) under the rules, unless and until it is published either—• (1) With a summary of characters (seu diagnosis; seu definition; seu condensed description) which differentiate or distinguish the genus or the species from other genera or species ; (2) Or with a definite bibliographic reference to such summary of characters (seu diagnosis ; seu definition ; sell condensed description). And further—- • (3) In the case of a generic name, with the definite unambiguous designation of the type species (seu genotype ; seu autogenotype ; seu orthotype). The purpose of this amendment is to inhibit two of the most important factors which heretofore have produced confusion in scientific names. The date, January 1, 1931, was selected (instead of making the amendment immediately effective) in order to give authors ample opportunity to accommodate them¬ selves to the new rule. The commission unanimously adopted the following resolution :—- (a) Jt is requested that an author who publishes a name as new shall definitely state that it is new, that this be stated in only one (i.e., in the first) publication, and that the date of publication be not added to the name in its first publication. (b) It is requested that an author who quotes a generic name, or a specific name, or a subspecific name shall add at least once the author and year of publication of the quoted name or a full bibliographic reference. The foregoing resolution was adopted in order to inhibit the confusion which has frequently resulted from the fact that authors have occasionally published a givenname as “ new ” in two to five or more different articles of different dates—up to five years in exceptional cases. * Reprinted from the Public Health Reports, United States Public Health Service (1927), Vol. 42, p. 2639, in which publication it is requested that the matter bo given as wide publicity as possible.
