50 to 100 generic names in their specialty which they look upon 

 as the most important and most generally used. Each name should 

 be accompanied by the füll and complete original bibliographic 

 reference, by the name of the type species, determined according 

 to Art. 30 of the International Rules, and by the name of the order 

 and family to which the genus belongs. 



3) All zoologists and paleontologists who give courses in Gene- 

 ral zoology are invited to supply the Secretary with a list of the 

 text books used in said courses so that said books may be indexed 

 for generic names. 



4) The Commission will alphabetize all the generic names sent 

 in and will endeavor, according to circumstances, to determine 

 which are the 100 to 500 most commonly quoted genera. 



5) The genera selected will be submitted to specialists in the 

 groups in question who will be requested to submit opinions on 

 the nomenclatorial status of said names. 



6) Upon return of the lists from the specialists, the Commis- 

 sion will endeavor to test the names, according to the International 

 Rules, and if feasible will publish a list of the genera in question 

 with their most commonly used names and their correct 

 names. 



7) If the undertaking is successful, the zoologists of the world 

 will be invited to give to the Commission the benefit of their cri- 

 ticisms not later than July 1, 191 2, so that the Commission can 

 restudy the names and submit to the next Congress. — 



8) An Officia] list of generic names, with 

 their genotypes; and with the 



9) Proposition that the Congress adopt said list and a 



10) Resolution to the effect that no zoologist shall upon 

 nomenclatorial grounds change any name in said list un- 

 less he first submits to the Commission his reasons for making 

 the change and unless the Commission considers the reasons valid. 



The Commission believes that this proposition is feasible, but 

 for the present views it in the light of an experiment, dependent 

 to no small extent upon the question whether a proper amount 

 of Cooperation is forthcoming. In this connection the Commission 

 takes the liberty of inviting attention to the fact that the greal 

 advances in nomenclature have been made by colleagues who have 

 showed a conviction in their views sufficient to induce them to de- 

 vote some time to the subject. 



Amendements to the „Regles internationales de la nomenclature

 ments to the present International Rules. Of these propositions,
