42 NORTH AMERICAN BIRDS. 



crown fe;illiers A\ith a narrow streak ol' black, those on crown indistinct. Beneath dull 

 while, tinged with ashy-ocliracoous across the breast and along the sides; crissum pale 

 ochraceous. An obsolete light superciliary, and narrow dusky niaxiUar}' stripe. Bend 

 of wing yellow; lesser coverts tinged with greenish-yellow. Length, G inches; wing, 

 2.65; tail, 3.00; bill, .32 from nostril, .25 deep at base ; tarsus, .80; middle toe, .63. 

 Hab. Los Nogales, Sonora, and Southern Arizona. 



This race lias a considerable resemblance to F. crstivalis, but differs in 

 some appreciable points. The brown of the upper parts is paler, and the 

 ashy edging to the feathers appears rather less extensive. The dark brown 

 blotches on the back are of greater extent, the black streaks on the back 

 confined to a mere streak along the shaft. There is less of an olive tinge 

 across the breast. 



The proportions of the present race differ more from those of ccstivalis 

 than do the colors, the bill being more slender, and the wmgs and tail con- 

 siderably longer. 



The resemblance to P. hottcrii (= cestivali% var. hotterii) of Sclater, from 

 Middle IMexico (Orizaba, Colima, etc.), is %ery close ; the difference being 

 greater in the projiortions than in the colors, the latter having a shorter wing 

 and tail, with tliicker bill, as in var. ccstivalis. In hottcrii there is rather a 

 predominance of the black over the rufous in the streaks above. 



Habits. Tliis, in its general habits, nesting, eggs, etc., probably resembles 

 the variety ccstivalis.

Sp. Char. (6,329 g, Texas; compared with type of species.) Ground-color of 

 upper parts grayish-a.*h ; the middle portion of each feather dull brown, in the form of a 

 blotch, and with a black shaft-streak, the latter becoming modified on scapulars, rump, 

 and upper tail-coverts, into transverse spots, those on the upper tail-coverts being large 

 and conspicuous, and in the forrri of crescentic spots, the terminal margin of the feathers 

 being lighter ashy in sharp contrast. Middle tail-feathers clear ashy, with a sharply 

 defined .^haft-streak of blacki.«h, throwing oS" obsolete, narrow, transverse bars toward 

 the edge ; rest of tail clear dusky-brown, the lateral feather with whole outer web, and 

 margin of the niner, dull white, all, except the intermediate, with a large, abruptly defined, 

 terminal space of dilute brown (decreasing in size from the outer), the margin whitish. 

 Upper secondaries broadly and sharply margined along both edges with dull ashy-white, 

 the enclosed portion being clear dusky brown, intensified where adjoining the whitish. 

 A very obsolete superciliary stripe of ashy, becoming whitish over the lore ; auriculars 

 more dingy, but without distinct stripe along upper edge. An uninterrupted but indis- 

 tinct " bridle " along sides of throat. Lower parts dull white, without any ochraceous, 

 but with a very faint ashy tinge over the jugulum ; flanks with broad, somewhat blended
