NO. I HISTORY OF ZOOLOGICAL NOMENCLATURE — STEJNEGER II 



"Art. I. La nomenclature adoptee pour les etres organisee est 

 binaire et binominale 



" Art. 44. Le nom attribue a chaque genre et a cliaque espece ne 

 pent etre que celui sous lequel ils ont ete le plus anciennement de- 

 signes, a la condition : . . . . 



" b. Que I'auteur ait effectivement entendu appliquer les regies de la 

 nomenclature binaire. 



"Art. 45. La dixieme edition du Systema fiatitrae (1758) est le 

 point de depart de la nomenclature zoologique. L'annee 1758 est done 

 la date a laquelle les zoologistes doivent demonter pour rechercher 

 les noms generiques ou specifiques les plus anciens, pourvu qu'ils 

 soient conformes aux regies fondamentales de la nomenclature." 



We see consequently that the International Zoological Congress 

 repudiated the idea of going back for the generic names beyond 1758 

 and definitely and unequivocally committed itself to the acceptance of 

 each generic and each specific designation dating from i^jS and 

 after, thus getting into complete accord with the provisions of the 

 A. O. U. Code. On this point, therefore, the French and the Ameri- 

 can zoologists were fully agreed. 



Between the first and the second international zoological congresses 

 (1889 and 1892) the Second International Ornithological Congress, 

 meeting at Budapest, 1891, also took up the matter of zoological 

 nomenclature, on the initiative of an " Entwurf von Regeln flir die 

 zoologische Nomenclatur," originating in Berlin and reported on by 

 Dr. Anton Reichenow. Recognizing that the A. O. U. Code (1886) 

 was " wohl der vollstandigste und am scharf sten durchdachte Entwurf 

 von Regeln fiir die zoologische Nomenclatur, welcher bis jetzt verof- 

 fentlicht worden ist," and noting that because of its " vorziiglichen 

 Eigenschaften " most American zoologists had given it their ap- 

 proval, the German " Entwurf " proposed to adhere as closely to it 

 as possible. Reichenow's proposal, with only a few verbal changes, 

 was adopted by the International Ornithological Congress under the 

 title "Regeln fiir die zoologische Nomenclatur" (Zweiter Interna- 

 tionaler Ornithologischer Congress, Budapest, 1891. Hauptbericht. 

 I, Officieller Teil, pp. 183-190). The special part, which consists of 

 14 articles, contains the matter in which we are at present interested. 

 Art. 5 reads as follows : " 5. Die allgemeine Giltigkeit des Prioritats- 

 gesetzes beginnt mit der X. Ausgabe von Linne's Systema Naturae 

 (1758). Erlauterung: Das Jahr 1758 gilt als Anfangszeit des Pri- 

 oritatsgesetzes ebensowohl fiir Gattungs- wie fiir Artnamen. Art- 

 namen solcher Schriftsteller, welche nicht die binare Nomenclatur im 

 Princip angewendet haben, konnen nicht beriicksichtigt werden, auch
