 Sept., 1917 SOME BIRDS OF TIlE DAVIS MOUNTAINS, TEXAS 165 Psaltriparus plumbeus. Lead-colored Bush-tit. Psaltriparus melanotis Iloydi. Lloyd Bush-tit. The relative distribution of 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- ceptin 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 leatilers and some had none. Hyloichla guttara 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. High Island, Texas, February 1, 1917. 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) HE 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 txvo recognizable races are represented, the habitats of which are separat- ed by the HudsonJan and Alpine-Arctic territory of the Sierran crest. Fur- thormore, the east-slope race is not referable to the Great Basin form schistace. a, as might have been expected.
