the Honorable Walter Rothschild, at the invitation of the Commission, 

 attended the meetings in an advisory capacity. 



3) The following active and advisory Commissioners were not in atten- 

 dance: Messrs. Apstein, Dolio, Jordan (D. S.), Ludwig, Mitchell, 

 and F. E. Schulze. 



4) Death. — It is with profound regret that the Commission reports 

 the death of one of its members, Professor Dr. F. C. von Maehrenthal 

 who died in 1910, very shortly after the Gratz meeting. Putting entirely 

 aside our feeling of j^ersonal loss as insignificant in comparison with the 

 loss thatCommissionervonMaehrenthaTs death means to the international 

 zoological profession , the Commission feels that it is only just to pause a 

 moment to recall to the members of this Congress the modest character of 

 this man who gave nearly his entire professional career to aiding his col- 

 leagues in their more tedious labors and than whom it would be difficult to 

 find, in the entire history of zoology, any man with a keener insight into 

 the intricacies and complications of zoological nomenclature with the possible 

 exception of Linnaeus and Strickland. 



5) Resignations. — During the interim since the 1910 session, the 

 Commission has received the following resignations, which are herewith re- 

 ported to the Congress with the recommendation that they be accepted: 



Doctor G. A. Boulenger (London), who declined to serve. 



Doctor Louis Dolio (Brussels), who begged to be excused from sei'- 

 vice, on the ground of poor health. 



The resignation of Professor Hubert Lud wig (Bonn) has been received, 

 but as his term of office expires with the present Congress no formal 

 action is necessary. 



6) Advisory or temporary Commissioners. ■ — Through the death 

 of Dr. von Maehrenthal and the resignations of Doctors Boulenger, 

 Dolio, and Ludwig, the Commission became reduced from 15 to 11 

 members. As it seemed very advisable not to permit the organization to 

 decrease in size, and as there was no method of procedure prescribed whereby 

 vacancies were to be filled in the interim between Congresses, the Com- 

 mission, acting in the interest of the subject, invited certain gentlemen to 

 fill the vacancies until these could be filled by the present Congress. The 

 gentlemen in question are as follows: 



Doctor P. Chalmers Mitchell, Secretary of the Zoological Society of 

 London, was invited to serve in place of Dr. Boulenger. 



Professor Kraepelin, of Hamburg, was invited to serve in place of 

 Dr. von Maehrenthal; Dr. Kraepelin served but a short time and Pro- 

 fessor Apstein, of Berlin, was invited to fill the vacancy. 



7) Upon reaching Monaco, the Commission invited Dr. K. Jordan, 

 Secretary of the International Committee on Entomological Nomenclature, 

 and the Honorable "Walter Rothschild, to sit with the Commission in an 

 advisory capacity and this has been done. 



8) Since not a single majority vote has been determined by the gent- 

 lemen in question, and therefore their temporary membership on the Com- 

 mission has in reality been equivalent to their serving simply in an advisory 

 capacity, the legality of the action taken can not be questioned on the ground 

 that these gentlemen wei-e not formally elected by the Congress. At the 

 same time, as a matter of formality the Commission at present asks that its
