been more essential as a renewal of worn plumage formerly than at 

 the present time. 



Cooper, in at least three places (1861, p. 122; 1869, p. 475; 1870a, 

 p. 75) made record of Spizella pallida from Fort Mohave. He states 

 that two specimens were secured. In the second citation Cooper even 

 emphasized that it was "not S. Brewerii" he had. A little later 

 (18706, p. 209) he for the first time gives Spizella breweri from Fort 

 Mohave, then without mention of 8. pallida. It always seemed prob- 

 able, therefore, that Cooper's "pallida," although quoted freely by 

 other authors, was really a misidentification of breweri. There are 

 no Cooper specimens of Spizella in the Museum of Vertebrate Zoology 

 bearing either name. At my request Dr. C. W. Richmond kindly 

 looked into the matter at the United States National Museum. lie 

 writes me that there is a specimen of Spizella breweri, so identified 

 by Ridgway and now no. 208619, labeled in Cooper's handwriting 

 "Spizella pallida," and taken by him at Fort Mohave, April 2, 1861. 

 This is evidently one of the skins upon which Cooper's record of 

 pallida was originally based, so that there is now no doubt but that 

 breweri was the species really involved. Needless to say, Spizella 

 pallida is not known from any station in this latitude so far west. 



Spizella atrogularis (Cabanis) 

 Black-chinned Sparrow 



California side opposite The Needles, in a ravine among the hills, 

 March 3, male taken (no. 13200) ; the only one of the species seen 

 on our whole trip. 



Junco oreganus thurberi Anthony 

 Sierra Junco 



In willow bottom, on California side at base of Riverside Mountain 

 March 17, female taken (no. 13135) ; the only junco of any sort seen 

 by us anywhere in the region. 



There is a well-preserved skin in the Museum (no. 4143) taken by 

 J. G. Cooper at Fort Mohave, December 24, 1860, and as stated by 

 Cooper (1870, p. 200) a few probably winter regularly in the Colorado 

 Valley.
