DESCRIPTIONS OF SUPPOSED NEW BIRDS FROM 

 LOWER CALIFORNIA, SONORA, AND CHIHUA- 

 HUA, MEXICO, AND THE BAHAMAS. 



BY WILLIAM BREWSTER. 



During the past year I have received a large number of birds 

 trom Mexico, representing three distinct collections, one made 

 by Mr, M. Abbott Frazar in Lower California between January 24 

 and December 31, 1887 ; another by Mr. J. C. Cahoon in the east- 

 ern central part of Sonora between January 31 and June iS, 1S87 ; 

 and the third by Mr. R. R. McLeod in the extreme western 

 portions of Chihuahua during the years 1883, 1884 and 1885. 

 The last, although comprising only about two hundred skins, 

 has proved particularly rich in new and little known birds. 



Full lists of the species taken or observed by each of these col- 

 lectors, with such field notes as they have placed in my hands, 

 will be prepared and published as soon as possible, the present 

 paper being restricted to the supposed new species or subspecies. 

 In determining these I have received invaluable aid from Mr. 

 Ridgway who has been at much personal trouble in examining 

 and reporting on the numerous specimens which I have submitted 

 to him, and through whose kind offices I have been able to 

 compare nearly all of the new birds witli series, often including 

 the types, ol their nearest alhcs trom the collection of the 

 National Museum. 



In my descriptions the names of colors have been determined,
