21 A. Brewster c« « Nezv Hummingbird, flu'ly 



Mr. Baily lias recently had the specimen mounted, and has 

 presented it to the Academy of Natural Sciences of Philadelphia, 

 where it is now exhibited in the collection of local birds which is 

 being formed for the museum by the Delaware Valley Ornitho- 

 logical Club. 



This bird, which is a male, combines the characters of Zono- 

 trichia albicollis and Ju/ico hyemalis in nearly equal propor- 

 tions. The upper surface and wings have the general aspect of the 

 Zoizotrichia, but the black shaft stripes are narrower and the 

 rufous is more or less suffused with slaty, this shade predomi- 

 nating on the head, where the central white stripe is entirely 

 obliterated and the black stripes considerably broken. Beneath 

 the pattern of coloration is that of the Zonotrichia, but the breast 

 and sides are of a darker slaty hue. The superciliary stripe is 

 reduced to a white spot behind the nostril and there is a faint 

 dusky maxillary stripe. The outermost tail feathers have the 

 terminal two thirds white, and there is a white terminal spot on 

 the inner web of the next pair. 



DESCRIPTION OF A NEW HUMMINGBIRD FROM 

 NORTHERN MEXICO. 



BY WILLIAM BREWSTER. 



Among the birds collected for me in Sonora, Mexico, in 1SS7, 

 by the late Mr. J. C. Cahoon, is a Hummingbird which I was 

 unable to identify until, during a visit to England in 1S91, I 

 showed it to Mr. Salvin who at once pronounced it to be a new 

 species. It may be characterized as follows : — 



Cyanomyia salvini. 1 Salvin's Hummingbird. 



Specific characters. — Similar to C. cyaneicollis, but smaller, with 

 shorter wings, shorter and squarer tail, but longer and slenderer bill ; 

 iridescent colors on sides of neck bordering the throat, blue like the crown
