will meet with the nppi^oval of both sides of the controversy, 

 namely : — 



(1) The Commission invites all zo (legists to send to the Secretary of the 



CoiDiuission, prior to November 1, I'JIO, a li.st. of lOU zooloo-ical generic 

 names vj-hich they consider should be studied in conneciion with the 

 preparation of an "Official List." Each name should be accompanied 

 either by the name of the author of the generic name, or by an indica- 

 tion of the group to which it belongs. 



(2) All systematists are invited to send a separate list of the 50 to 100 



genei'ic names in their specialty which they look upon as the most im- 

 portant and most generally used. Each name should be accompanied 

 by the full and complete original bibliographic reference, by the name 

 of the type species, determined according to Art. 30 of the Inter- 

 national Rules, and by the name of the order and family to which the 

 genus belongs. 



(3) All zoologists and palseontologists who give courses in General 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 



endeavour, 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 Commission will 



endeavour 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 coriect names. 



(7) If the undertaking is successful, the zoologists of the world will be in- 



vited to give to the Commission the benefit of their criticisms not later 

 than July 1, 1912, so that the Commission can restudy the names and 

 submit to the next Congress : 



(8) An official 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 nomknclatoriaTj 

 grounds change any name in said list itnless he first submits to the 

 Connnission his reasons for making the change and unless the Com- 

 mission 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 co-operation is forthcoming. In this connection the Commission 

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

 advances in nomenclature have been made by colleagues who have 

 showed a conviction in their view sufficient to induce them to 

 devote some time to the subject.
