Sept., 1917 SOME BIRDS OF THE DAVIS MOUNTAINS, TEXAS 1G5 



Psaltriparus plumbeus. Lead-colored Bush-tit. Psaltriparus melanotis lloydi. 

 Lloyd Bush-tit. The relative distribution cf these two species in the mountains under 

 discussion has not been well determined. The Lead-colored Bush-tit is much the com- 

 moner species, and ranges over the entire mountain range, wherever cover exists, up to 

 the edge of the pines. Limpia Canyon is given as the type locality for lloydi, but, ex- 

 cepting perhaps in winter, that species rarely descends below 6000 feet. It is partial to 

 the willow-like oaks on the more shaded slopes just below the pines. During September 

 few bush-tits possessed full complements of tail feathers and some had none. 



Hylocichla guttata auduboni. Audubon Hermit Thrush. Three, possibly four, 

 forms of this species are transients or winter visitants in western Texas. The above 

 named form is the first to arrive, and was the only one met with during my stay. It was 

 very common in suitable situations above 6000 feet.

A NEW RACE OF FOX SPARROW, FROM THE VICINITY OF 



MONO LAKE, CALIFORNIA 



By JOSEPH GRINNELL and TRACY I. STORER 



(Contribution from the Museum of Vertebrate Zoology of the University of California) 



THE collections obtained in the Yosemite region in 1914-16 for the Museum 

 of Vertebrate Zoology include series of breeding Fox Sparrows from both 

 slopes of the Sierra Nevada. Examination of this summer material shows 

 that two recognizable races are represented, the habitats of which are separat- 

 ed by the Hudsonian and Alpine-Arctic territory of the Sierran crest, Fur- 

 thermore, the east-slope race is not referable to the Great Basin form schistacca, 

 as might have been expected.
