Rules for fJie Scientific Naming of Animals, com^pilecl by the German 

 Zoological Society, 



A. GBNBHAL EUIES, 



1. Zoological Nomenclature includes extinct as well as recent 

 animals, but has no relation to botanical names. 



2. Only such scientific names can be accepted as are published in 

 print, in connection with a clear description either by words or 

 figures. 



3. Scientific names must be in Latin. 



4. Names of the same origin and only differing from each other 

 in the way they are written are to be considered identical. 



5. Alterations in names otherwise valid are only permitted in 

 accordance with the requirements of Sections 13 and 22, and further 

 for the purpose of purely orthographical correction when the word 

 is without doubt wrongly written or incorrectly transcribed. Such 

 alterations do not affect the authorship of the name. 



6. Of the various permissible names for the same conception only 

 the one first published is valid (Law of Priority). 



7. The application of the Law of Priority begins with the tenth 

 edition of Linnseus's ' Systema Natur86 ' (1758). 



8. When by subsequent authors a systematic conception is 

 extended or reduced, the original name is nevertheless to be 

 regarded as permissible. 



9. The author of a scientific name is he who has first proposed it 

 in a permissible form. If the author's name is not known, the title 

 of the publication must take its place. 



10. If the name of the author is given it should follow the scien- 

 tific name without intervening sign. In all cases in which a second 

 author's name is used a comma should be placed before it. 



11. Class (classis). Order {ordo),'Family(familia), Genus (genus), 

 and Species {species) are conceptions descending in rank one after 

 the other, and are to be taken in the order here given. These 

 terms should not be employed in a contrary or capricious relation 

 or order. 



B. BULES POn DESIGNATING SPECIES. 



12. Every species should be designated by one generic and one 

 specific name (Binary Nomenclature). 



13. The specific name, which should be treated always as one 

 word, should depend grammatically upon the generic name. 



14. The same specific name can only be used once in the same 

 genus. 



15. In the case of a species being subdivided, the original name is 

 to be retained for the species which contains the form originally 

 described. In doubtful cases the decision of the author who makes 

 the separation shall be followed. 



16. "When various names are proposed for the same species nearly
