Zoological Nomenclature. 1S7 



Example: Tcenia pectinata Goeze, 1782 = Cittotcenia pectinate 

 (Goeze) Raill., while " Tcenia pectinata Goeze " von Zeder, 1800 = 

 Andrya rhopalocephala (Riehm). Andrya pectinata (Zeder) could 

 not be admitted. 



23. 



When a species is divided, the restricted species to which the 

 original specific name of the primitive species is attributed may 

 receive a notation indicating both the name of the original author 

 and the name of the reviser. 



Example : Tcenia pectinata Goeze partim, Riehm. 



By application of Rule 22 both the name of the original author 

 and of the reviser are placed in parentheses if the species is trans- 

 ferred to another genus. 



Example : Monieza pectinata (Goeze partim, Riehm) Blauchard. 



24. 



A genus formed by the union of several genera takes the oldest 

 valid generic or subgeneric name of its components. If the 

 names are all of the same date, that selected by the first reviser 

 shall be retained. 



25. 



The same rule is applicable when several species or subspecies are 

 united to form a single species. 



26. 



When, in consequence of the union of two genera, two different 

 animals having the same specific or subspecific name are brought 

 into one genus, the more recent specific or subspecific name falls 

 as a synonym. 



VI. Family and Subfamily Names. 

 27. 

 The name of a family is formed b} r adding the ending idw, tho 

 name of a subfamily by adding ince, to the root of the name of its 

 type genus. 



28. 



The name of a family or subfamily should be changed when the 

 generic name serving as a type is changed. 



VII. The Law of Priority. 

 29. 

 The name of a genus or species can only be that name under 

 which it was first designated, on the condition: 



a. That this name was published and clearly defined or in- 

 dicated. 

 6. That the author has properly adopted tho principles of 

 binominal nomenclature.
