Official list of most frequently used zoological names. 

 There is a desire on the part of some zoologists that 

 certain very commonly used zoological names should be ex- 

 cepted from the application of the Law of Priority, 

 and a proposition to this effect has been presented to the Commis- 

 sion from the British Association for the Advancement of Science 

 and the Eastern Branch of the American Society of Zoologists. 

 That this desire is so widespread and so deeply rooted as is assum- 

 ed by some of our colleagues has not been confirmed by inquiries 

 made by several members of the Commission. Further, an effort 

 made by the Secretary to collect from zoologists the most com- 

 monly used and most important generic names has as yet met 

 with such poor success that the conclusion does not seem entirely 

 unjustified that some of our colleagues who may be in favor of 

 such a list are not as yet sufficiently enthusiastic over the propo- 

 sition to induce them to demonstrate their desire by placing into 

 the hands of the Commission the data upon which such a list must 

 of necessity be based. Further, there are many colleagues who 

 are known to us to be directly and enthusiastically opposed to 

 such a list. 



After careful consideration of the subject and of the many 

 difficulties involved, the Commission has decided to propose to 

 the Congress the trial of a proposition which it is hoped will meet 

 with the approval of both sides of the controversy, namely: 



1) The Commission invites all zoologists to send to the Secre- 

 tary of the Commission, prior to November 1, 1910, a list of 100 

 zoological generic names which they consider should be studied 

 in connection 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 indication of the group to which it belongs. 



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