of the Providence Mountains), in the Panamint, Inyo, and White 

 mountains, and on the east slope of the Sierra Nevada, from Carroll 

 Creek at the south, northward an undetermined distance. 



Specimens examined from the following localities.— Inyo County : 

 Mazourka Canyon, Inyo Mountains; Carroll Creek, Lone Pme 

 Creek, and Kearsarge Pass, Sierra Nevada. Total number of 



specimens, 10. 



Distinguishing Characters.— Colorsitlon of adults umformly 

 grayish throughout, with no distinctive markings. Upper parts 

 gray; in fresh fall plumage the dorsum is tinged with olivaceous, 

 in slight contrast to the head. No decided markings on head, 

 though the cheeks are brownish, rather sharply defined against 

 the gray of neck and white of throat. Under parts pale gra, 

 tically pure white in worn plumage; the flanks frequently u- 

 with Vinaceous. Juveniles are usually plainly marked as are the 

 adults, but frequently exliibit head markings of varying extent 

 and sharpness, similar to those seen in P. melanotis. In measure- 

 ments, plumbeus as compared with minimus has wing and tail 

 longer, tarsus the same, and bill (both in length of culmen and bulk) 



jr^^,„f,^/.5,_ Besides the California specimens listed above, there 

 have been available for comparison series from southern Arizona 

 and from Nevada, numbering thirty-seven and seventeen skins, 

 respectively. These satisfactorily illustrate seasonal variation m 

 plumage, and the series also contain a good representation of birds 

 in Juvenal plumage. The California specimens are for the most 

 part absolutely like those from Arizona and Nevada. Birds from 

 the Inyo Mountains and Kearsarge Pass, taken in May and June, 

 are in worn breeding plumage, and are indistinguishable, either in 

 color or measurements, from comparable examples from other 



regions. . 



Two specimens from the Sierra Nevada, however, are deservmg ot 

 special notice. These are no. 22657, an adult male, taken on Lone 

 Pine Creek, April 13, 1912, in comparatively unworn plumage; and 

 no. 21092, also an adult male, taken on Carroll Creek, September 9, 

 1911, about two-thirds through the annual molt. The Lone Pine 

 bird has a distinctly perceptible "cap" on the pileum, not nearly 

 as marked as in full-feathered examples of californieus from the
