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; 1870«, 

 p. 75) made record of Si»zclla jmlJida from Port Mohave. He states 

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

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

 (1870&, p. 209) he for the first time gives Spizella brarrri from Fort 

 Mohave, then without mention of >f. pallida. It alwa\s seemed prob- 

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

 other authors, was really a misidentiticatiou of hrcicrri. There are 

 no Cooper specimens of Spizella in the Museum of Vertebrate Zooloi>y 

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

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

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

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

 "Spizella pallida." and taken by liim 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

 ^larch :>. male taken (no. 13200) : the only one of the species seen

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

There is a well-preserved skin in the ilaseum (uo. 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.
