Dr. Jonathan Dwight^ Jr. Mr. D. G. Elliot upholds Cygnus 

 as the proper generic terra for the White Swans, as against 

 the claims of Olor ; he next discusses some other species and 

 genera ; and goes on to arrange the Turkeys as Meleagris 

 fera, Pennsylvania to Florida^ west to Wisconsin and Texas ; 

 M.fera osceola, Florida; M. intermedia, Southern Texas and 

 Eastern JNIexico^ below .'2000 feet ; and M. gallopavo, Western 

 Texas to Arizona, and tablelands of Mexico. Dr. T. S. 

 Roberts gives an interesting account of Protonotaria ciirea, 

 illustrated with fine photographs of the extraordinary places 

 often selected by this Warbler for its nest. Mr. Ridgway 

 concludes his list of new subspecies of Fringillidse, and 

 starts with the Corvidse ; while Mr. Oberholser gives his 

 opinion that Geothlypis trichas arizela of the Pacific coast 

 is subspeeifieally distinct from the Nevada bird. Of wider 

 interest is Mr. Maekay's descri})tivc paper on the Terns 

 and Laughing Gulls of Muskeget and Pcnikese Islands. 

 Mr. Ruthven Deane records the shooting of the European 

 Wigeon {Mareca penelope) in Indiana, making the ninth 

 occurrence of this duck in the interior of the United States. 

 No. 4 opens with an article by Mr. Witmer Stone^ illustrated 

 by coloured figures of the male of the Rose-breasted Gros-

 plumages. Mr. S. N. Roads follows with notes on some of the 

 rarer birds of Western Pennsylvania ; and Mr. F. J. Birtwell 

 remarks upon aptosochromatism (colour-change without 

 moult) ^ as influenced by diet^ in Megascops asio ; while 

 Mr. J. Bickerton Williams contributes an interesting article 

 on the colour of certain birds in relation to inheritance. 

 In a rare literary and scientific jf)urnal, the ' Registro 

 Trimestre/ published in Mexico in 18;32 and 1833, Mr. C. 

 W. Richmond has found (in vol. ii.) descriptions of five 

 species of Trochilidse which had been overlooked, and these 

 he copies verbatim, giving his identifications. Another 

 valuable bit of research by Mr. Richmond is his article on 

 the date of Lacepede's " Tableaux.^^ Mr. Oberholser con- 

 tributes a monograph of the genus Contopus ; and Dr. J. A. 

 Allen gives a very useful republication of descriptions of
