630 Miscellaneous. 



original bibliographic reference, by the name of the t)'pc 

 species, determined according to Art. 30 o£ the International 

 Kules, and by the name of the order and family to which 

 the genus belongs. 



(3) All zoologists and palaeontologists 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. 



(G) Upon return of the lists from the specialists the Commission 

 will endeavour to test the names, according to the Inter- 

 national Hules, 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 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 nomen^- 

 CLATORiAL grounds change any name in said list unless 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 

 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.
