almost white in a poor light, ami the upperparts are very gray, 

 with scarce a tinge of greenish. 



Among the large series of Yellow Warblers before me I find 

 four from Southern Arizona* and one from Western Texas (Fron- 

 tera) which are referable to sonorana. A Colorado example is a 

 fair intermediate between sonorana and morcomi. Typical 

 inorcoml is represented from Utah, California, Lower California, 

 and Alaska. I also have two specimens from Sonora, but both 

 were taken early in the season and doubtless were migrants bound 

 further north. 



NOTES ON THE BIRDS OF FORT KLAMATH, 

 OREGON. 



BY DR. J. C. MERRILL, U. S. A. 



With remarks on certain species by Willia?n Brewster. 



In the fourth volume of the 'Bulletin' of the Nuttall Ornitholog- 

 ical Club,t Dr. Mearns published a list of the birds of Fort Kla- 

 math, based upon the observations and collections of Dr. H. 

 McElderry and Lieut. W. Wittich, U. S. A. The following 

 paper is the result of my own collecting at the same place from 

 September, i8S6, to August, 1S87, only such species as were 

 personally observed or obtained^ by myself being recorded. 

 These include most of the land birds mentioned in Dr. Mearns's 

 Iist,§ and a good many others ; the water birds are relatively 



* Since the above was written Mr. Allen has kindly sent to me for examination seven 

 specimens (three males and four females) taken in Pinal County, Arizona, by Mr 

 Scott. All of these prove to be sonorana. They form part of the series of eleven spec- 

 imens whose peculiarities were commented on with some detail in the last issue of Mr. 

 Scott's paper (Auk, Vol. V, No. i, p. 34). In the absence of sufficient material for com- 

 parison, Mr. Allen, at that time, very naturally referred them to morcomi.

 is now in the possession of Mr. William Brewster, whose comments on technical points 

 of especial interest are included in the present paper.
