REPUBLICATION OF DESCRIPTIONS OF NEW 



SPECIES AND SUBSPECIES OF NORTH 



AMERICAN BIRDS. 



BY J. A. ALLEN. 



Requests have been received from various members of the 

 A. O. U., who have not full access to the current literature of 

 ornithology, for the republication in 'The Auk' of the descrip- 

 tions of all new species and subspecies of North American birds 

 described in other publications than this journal. In response 

 to such requests the Council of the A. O. U. has authorized such 

 republication, of which the first instalment here follows, begin- 

 ning with those included in the ' Ninth Supplement ' to the Check- 

 List (see Auk, XVI, Jan., 1899, pp. 97-133), and including 

 those since published to date. 



In this republication the original diagnoses or descriptions are 

 given in full, and such additional remarks as are essential to a 

 proper presentation of the case, in the exact words of the author, 

 unless otherwise indicated by the omission of marks of quotation. 

 Later instalments of similar scope and character will be given at 

 the close of each year.
