fil.ANCMARD : INTERNATIONAL RULES OF ZOOLOGICAL NOMENCLATURE. 183 



the three members of the sub-committee should meet and devote to 

 the revision entrusted to them the time required by such a difficult 

 work. Various circumstances combined to prevent such a meeting ; 

 Dr. Stiles in particular was recalled by his official duties to America 

 immediately after the Berlin Congress, and was unable to return to 

 return to Europe until the Congress at Berne, in August, 1904 ; and 

 hence it is that the code of rules which the Congress at Berlin had 

 decided to publish appears only after a delay of three years. 



In consequence of the resignation of Messrs. Saunders and Sclater, 

 above mentioned, and of the death of Professor J. V. Carus, the Inter- 

 national Commission became reduced to twelve members. A number 

 of these had not actually taken part either in the Congress at Berlin 

 or in that at Berne, and hence the Commission thought it desirable 

 to modify its constitution, and to divide itself by lot into three sections, 

 the members of one of which should retire in succession every three 

 years, and be replaced by members newly elected, those who retired 

 being eligible for immediate re-election ; in this way the continuity of 

 the work of the Commission would be assured. 



The Congress at Berne adopted this proposal unanimously, and the 

 course above mentioned was immediately adopted. The twelve 

 members of the Commission were divided by lot into three groups, 

 the first group retiring at once ; seven new members were then elected, 

 so that at the present moment the Permanent International Commis- 

 sion is composed of the following members : — 



Retiring in igo'j : — Dr. R. HoRST (Leyden), Dr. F. A. Jentink 

 (Leyden), President D. Starr Jordan (Palo Alto, California), Prof 

 F. E. ScHULZE (Berlin), Dr. L. Stejneger (Washington D.C.). 



Retiriiig in igio : — Prof R. Blanchard (Paris), Prof L. Joubin 

 (Paris), Dr. Ch. W. Stiles (Washington, D.C.), Prof. Th. Studer 

 (Berne), Prof R. R. Wright (Toronto). 



Retiri7igin igij: — M. Ph. Dautzenberg (Paris), Dr. W. E. Hoyle 

 (Manchester), Prof L. von Graff (Graz), Prof F. C. von Maeh- 

 renthal (Berlin), Prof H. F. Osborn (New York). 



Professor Blanchard is President of the Commission, and Dr. von 

 MaehrenthaL and Dr. Stiles Secretaries. They constitute an 

 Executive Committee which receives all questions relating to nomen- 

 clature, and according to circumstances either decides them at once 

 or refers them to the Permanent Commission. 



At the end of the Sixth Congress (15-20 August, 1904) Messrs. 

 Blanchard, von Maehrenthal, and Stiles remained for some 

 time at Berne in order to complete the task which the Congress had 

 entrusted to them. From the 21st to the 28th of August they met 

 daily at the Zoological Institute of the University. Their task is now
