INTERNATIONAL RULES FOR ZOOLOGICAL NOMENCLATURE 



Adopted by the International Zoological Congress. 



Continued from page 185. 



RULES AND RECOMMENDATIONS. 



General Considerations. 



Article i.^ — Zoological nomenclature is independent of botanical 

 nomenclature in the sense that the name of an animal is not to be 

 rejected simply because it is identical with the name of a plant. If, 

 however, an organism is transferred from the vegetable to the animal 

 kingdom, its botanical names are to be accepted in zoological nomen- 

 clature with their original botanical status ; and if an organism is 

 transferred from the animal to the vegetable kingdom, its names retain 

 their zoological status. 



RECOMMENDAriON. — It is well to avoid introducing into zoology as generic 

 names such names as are in use in botany. 



Art. 2. — The scientific designation of animals is uninominal for 

 subgenera and all higher groups, binominal for species, and tri- 

 nominal for subspecies. 



Art. 3. — The scientific names of animals must be words which 

 are either Latin or Latinized, or considered and treated as such in 

 case they are not of classic origin. 



Family and Subfamily Names. 



Art. 4. — The name of a family is formed by adding the ending 

 idae, the name of a subfamily by adding inae, to the root of the 

 name of its type genus. 



Art. 5. — The name of a family or subfamily is to be changed 

 when the name of its type genus is changed. 



Generic and Subgeneric Names. 

 Art. 6. — Generic and subgeneric names are subject to the same 

 rules and recommendations, and from a nomenclatural standpoint 

 they are co-ordinate, that is, they are of the same value. 



Art. 7. — A generic name becomes a subgeneric name when the 

 genus so named becomes a subgenus, and vice versa. 



Art. S. — A generic name must consist of a single word, simple or 

 compound, written with a capital initial letter, and employed as a 

 substantive in the nominative singular. Examples : Canis, Perca, 

 Ceratodus^ Hyinenolepis. 



Recommendations. — The following words may be taken as generic names: 



a. Greek substantives, for which the rules of Latin transcription (see Appendix F) 

 should be followed. Examples: Ancyh(s, Amphihola. Aplysia, Pomplwlyx, Physa, 

 Cylickna.
