'Aves' in the Zoological Record for 1917. l — Since 1914 the Royal 

 Society of London has been unable to continue the publication of the 

 'International Catalogue of Scientific Literature' but the Zoological 

 Society has continued to publish the 'Zoological Record' and has recently 

 issued the volume for 1917 which would have been Vol. N, Zoology of 

 the 'International Catalogue.' The titles on Birds have been arranged 

 by Mr. W. L. Sclater, who for several years has edited this subject with 

 commendable devotion and skill. The titles number 707 as compared 

 with 942 for 1916, the falling off of course being due to the war and its 

 many distractions. Nevertheless, under the circumstances the number 

 of papers is remarkable and is nearly 50 per cent, greater than those on 

 all other vertebrates combined, nearly half as many as those relating to 

 insects, and more than those in any group of invertebrates except insects. 



As usual the papers are arranged under three main headings, 'Titles', 

 'Subject Index' and 'Systematic'. In the 'Subject Index' the titles are 

 distributed under seven principal divisions: 'General', 'Structure', 'Physi- 

 ology', 'Embryology', 'Ethology', 'Variation', and 'Geography'. As 

 might naturally be expected the greater part of the publications are either 

 faunal or systematic. The new generic and subgeneric names number 

 25, of which twelve were proposed by Mathews, five by Oberholser, two 

 by Todd, and one each by Chapman, Chubb, Kuroda, Murphy, Richmond 

 and A. Roberts, but very few of them affect North America birds. The 

 'Record' is indispensable to students who wish to keep in touch with cur- 

 rent ornithological literature of the world and those who do not have 

 access to the full volume should secure from the publishers a separate 

 of the part relating to 'Aves.' — T. S. P. 



Stresemann's 'Avifauna Macedonica'. — A collection of upwards of 

 3000 skins of birds representing 168 species was made in Macedonia by 

 Dr. F. Doflein and Prof. L. Muller in 1917 and 1918 and deposited in the 

 Zoological Museum at Munich. This collection forms the basis of the 

 present exhaustive report 2 on the birds of that country by Dr. E. Strese- 

 mann. 



Under each species there is a complete list of specimens, usually a 

 large series, followed by paragraphs on the sequence of plumages, molts,
