the Lower California bird receiving the new name castaneicefs. Seven 

 species and ten subspecies of" Golden Warblers are now recognized 

 only two of which ( D. cestiva and D. brydnti castaneicefs) pertain 

 to the fauna of North America, as defined in the new 'A. O. U. Check 

 List,' the remainder being West Indian and Central American. — J. A. A. 



Ridgway on the Type Specimen of Buteo oxypterus Cassin.* — A re- 

 examination of the type specimens of Buteo oxypterus Cassin. preserved 

 in the Museum of the Philadelpbia Academy of Natural Sciences, lias led 

 Mi. Ridgway to refer B. oxypterus to />. s-wainsoni as a pure synonym, 

 the type of oxypterus pro\ ing to be unquestionably a young />'. s-wainsoni. 

 'Upon the whole," says Mr. Ridgway, "I cannot see the slightest reason 



for recognizing ' B. oxypterus' even as a local race of s-wainsoni " 



lie also adds that the " specimen described in ' History of North American 

 Birds' (III, p. 266) as the melanistic adult of ' Buteo s-wainsoni var. oxyp- 

 terus is not B. s-wainsoni at all. but B. fuliginosus Scl." Comparative 

 diagnoses are given of these two species. — J. A. A. 



Ridgway's List of Emended Names of North American Birds, f — The 

 nanas ••represent new or hitherto unpublished combinations" adopted by 

 the A. O. IT. 'Committee on Classification and Nomenclature of North 

 American Birds.' '-They are here presented in order that the first known 

 use of such combinations may be cited among the references which the 

 committee has decided to give under each species, viz., the first pertinent 

 binomial or trinomial appellation, and the first use of the name as adopted 

 in the new list now being prepared by the committee." The changes, 

 some 77 in number, relate chiefly to the generic part of the name, ami 

 result largely from the depression of formerly current genera to the rank of 

 subgenera, partly from the change of status of the form in question from 

 specific to subspecific rank, or the reverse, and in small part from actual 

 change of names, found necessary on synonymic grounds. Comparatively 

 few are therefore of a very 'radical' character, and are mainly the follow- 

 ing, with which are given their current equivalents.
