E V I O R A Miaseiiim of Cooiparative Zoology Cambridge, Mass. June 29, 1956 Number 58 SEQUENCE OF PASSERINE FAMILIES (AVES) By E. Mayr and J. C. Greenway, Jr. At the XI International Ornithological Congress at Basel, Dr. Stresemann proposed that a committee be appointed which would recommend to the editors of ornithological journals a standardized sequence of the families of Passerine birds. Dr. Stresemann pointed out that some editors follow Hartert, others Sharpe's Handlist, others the sequence of the AOU, and still others the recently proposed sequence of Mayr and Amadon (1951). If a reader wants to find a given family in an article, he may have to look either at the beginning or in the middle or at the encl depending on the particular sequence adopted by the i-espective editor. As a result of Dr. Stresemann 's suggestion a committee was appointed by the president of the Congress with the following members : Dr. G. C. A. Juuge, Chairman Eijksmuseum Nat. Hist., Leiden Prof. J. Berlioz Museum d'Hist. Nat., Paris IMof. Dr. G. Dementiev Zool. Mus. University, Moscow Prof. E. Mayr Mus. Comp. Zool., Cambridge, (Mass.) Mr. R. E.
