than the tail, more bluish ; loss so, however, than the scapulars. 

 Lores whitish, quite in contrast with the black of the forehead; 

 cheeks and ear-coverts dark-ashy, slightly washed with reddish, 

 and with obscure darker streaks; chin and throat white, with sparse, 

 hair-like shaft-streaks of black. Breast, abdomen, sides, Hanks, 

 and tibice fine vinaceous-rufous, the feathers (except on tibia?) 

 with fine hair-like shaft-streaks of black ; breast, abdomen, sides, 

 and flanks with pairs of transverse ovoid white spots, not touch- 

 ing the shaft ; on the abdomen the white and rufous bars are of 

 about equal width; on the tibia? the rufous is deepest, and exceeds 

 the white ; anal region barred with rufous, more faintly than the 

 abdomen ; lower tail-coverts immaculate snowy-white. Sides of the 

 neck deep reddish-ash}', this washing the whole side of the breast. 

 Lining of the wing reddish-white, with numerous crowded, cord- 

 ate, somewhat blended spots of rufous ; larger coverts trans- 

 versely spotted with blackish ; under side of primaries silvery-white 

 (blackish for about the terminal inch), crossed with quadrate spots 

 of blackish, of which there are about seven on the longest quill 

 (fourth) ; the basal ones are, however, so much broken, that the 

 number is rather indefinite. Wing, 9.10; tail, 8.20 ; culmen, .65; 

 tarsus, 2. GO ; middle toe, 1.50. 



No. 06,237, Westfield, Massachusetts, October 10, 1846. Yery 

 similar to the preceding (No. 12,024), but even darker, the rufous 

 of the lower parts deeper, and the ashy tinge on the side of the 

 breast still stronger. Wing, 9.20 ; tail, 8.15; culmen, .65 ; tarsus, 

 2.55 ; middle, 1.50. 



No. 6,874, Sacramento Valley, California, differs from the two 

 preceding in having the entire breast barred with rufous and 

 white, instead of having the two sides ashy, the white bars re- 

 stricted to the middle line ; the black of the pileum terminates 

 abruptly on the occiput, and the sides of the neck are tinged with 

 rusty, as in females. Wing, 9.30; tail, 8.15; culmen, .60 ; tarsus, 

 2.45; middle toe, 1.50. It resembles No. 10,086, except that the 

 colors are uniformly of a darker shade throughout. 



No. 2,554 (Mus. R. R.), Washington, D. C, differs from No. 

 10,086, in paler colors, and more delicate shades ; the sides of the 

 breast have a distinct wash of pearby-ash, while the nape is pale 

 bluish-ash, lighter than the back, and abruptly defined against the 

 dark plumbeous crown. Wing, 9.40 ; tail, 8.30 ; culmen, .65 ; 

 tarsus, 2.50; middle toe, 1.55.
