18 i Letteis, Extracts, and Notes. 



The present issue contains a list of 1576 titles dealing 

 with various aspects of ornithology, as compared with 16G5 

 for the year before ; of these 370 are British, 368 come 

 from the United States, 309 from Germany, and 130 from 

 Fi ance. The other countries which run into double figures 

 are Russia 82, Italy and Australia 52 each, Austria 46, 

 India 32, Holland 27, Finland 25, and the South African 

 Union 16. 



It is to be hoped that tlie war will not prevent the issue 

 of the volume for 1914, tliongh it will doubtless be a matter 

 of great difficulty to complete it. Not only has the war 

 caused the cessation of the issue of a great many periodicals, 

 but it will be impossible for the Central Bureau to receive 

 the foreign titles from many of the contributing countries, 

 even if the organizations and bureaus in these countries 

 still continue their work. We understand, however, that an 

 effort will be made to issue the volume for the present ^ear 

 and to make it as complete as possible, and in the meantime 

 all ornithologists can assist in making the financial burden, 

 which is undertaken by the Royal Society, less by subscribing 

 for a copy of the work. 



The New Edition of the B. 0. U. List of British Birds. — 

 This work is now complete and printed off except for the 

 Index, and it is hoped that it will be ready for issue to 

 subscribers early in February. The special subscription price 

 to Members has been fixed at 5s. 6c?., delivered free, and the 

 Secretary will be glad to receive remittances as soon as 

 possible. If Members would kindly enclose this amount 

 when sending their annual subscriptions, it would be a 

 convenience.
