(No. 38,423 ? % ; Laramie Peak.) Graduation of tail rather less than one- fourth of its total length. Fourth quill longest; 3d scarcely shorter; then the 5 th ; 2d longer than 6th ; exposed portion of 1st about half that of longest. Above pure light bluish-ash; beneath, including axillars, pure unbroken white. A very narrow frontal line with all the nasal feathers, and continu- ous with a broad stripe through and behind eye, involving entire ear cov- erts, with the wings and tail, bill and feet, deep black (the lesser wing coverts, however, like the back) ; the cheek stripe extending narrowly above the eye and broadly below it, and not varied with white on the lower eyelid. The forehead and side of vertex in contact with the black stripe, as far as posterior border of eye, hoary, almost pure white, shading oflF quite abruptly into the ash of head; the scapular feathers, where they overlap the wings, as well as upper tail coverts, similarly white, and shading into the adjacent ash; the coverts, however, slightly glossed with ashy, especially above. The tips of the secondary qiiiUs, and a, conspicuous patch across the base of the primaries (visible externally in the closed wing) are white ; this involves both webs of the primaries (except perhaps the 1st), and extends about as far as the tip of the 1st primary, occupying more and more space from the outer to t
