200 Recently published Ornithological Works. 
Dr. Jonathan Dwight, Jr. Mr. D. G. Elliot upholds Cygnus 
as the proper generic term 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 Mexico, 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 Corvidae; while Mr. Oberholser gives his 
opinion that Geothlypis trichas arizela of the Pacific coast 
is subspecifically distinct from the Nevada bird. Of wider 
interest is Mr. Mackay’s descriptive paper on the Terns 
and Laughing Gulls of Muskeget and Penikese 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¬ 
beak ( Zamelodia ludoviciana ) in immature and adult winter 
plumages. Mr. S. N. Roads follows with notes on some of the 
rarer birds of Western Pennsylvania ; and Mr. F. J. Birtwell 
remarks upon aptosochroinatism (colour-change without 
moult), as influenced by diet, in Megascops asio; while 
Mr. J. Bicker ton Williams contributes an interesting article 
on the colour of certain birds in relation to inheritance. 
In a rare literary and scientific journal, the f Registro 
Trimestre/ published in Mexico in 1832 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
