Three specimens of this interesting species were procured by Mr. Frazar 

 north of La Paz, on the Gulf of California. It is described as " differing from 

 the North American bird in having a stouter and more depressed bill, little or 

 no white on the eyelids ; the back, scapulars, and wing-coverts, richer and 

 deeper brown, the primaries and tail feathers, darker : the upper tail-coverts, 

 more or less varied with brown and white ; the lateral under tail-coverts, marked 

 with brown ; the bend of the wing and greater under primary coverts, mottled 

 with black ;ind white ; from the Galapagos species in the rather shorter bill 

 and distinctly brown (instead of sooty black) back, scapulars and wing-coverts, 

 dark markings on the under tail-coverts, and the greater amount of white on 

 the under primary coverts ; from both the above-mentioned species in the 

 broad zone of mottled black and white feathers extending across the breast. 

 Extreme measurements, three specimens, all males: wing, 9.75 to 10.27 ; tail, 

 3.90 to 4.26 ; tarsus, 2.18 to 2.30 ; bill, length from nostril, 2.35 to 2.37 : from 

 leathers, 2.99 to 3.05; depth at angle, 49.53." (Brewster, Auk. V., Jan.,
