96 BREWSTER, Descriptions of New Birds. [April 
including that of the throat, abdomen, and under tail-coverts thickly and 
coarsely streaked with dull black; under wing-coverts and lining of wings 
buffy white, without spots; eyelids buffy white; throat tinged with faint 
yellow but no yellow on crown, rump, or sides of breast. 
Habitat. Sierra Madre Mountains (Pinos Altos) of Chihua- 
hua, Mexico. 
This Warbler is perhaps the most beautiful and interesting bird 
discovered by Mr. Frazar in Mexico. It is evidently closely al- 
lied to D. audubonz, so closely in fact that the two may prove to 
intergrade. No indications of such intergradation are afforded, 
however, by my large series of awdubonz from western Mexico, 
all the specimens of which appear to be typical. Of D. xigrifrons 
Mr. Frazar took only five examples, including the three above 
described; the remaining two being an adult male (wing, 3.10; 
tail, 2.30 inches) and a young bird in first plumage, both shot at 
Pinos Altos, July 13, 1888. The former is closely similar to the 
type, but has the nape less spotted and the black of the head a 
trifle duller. . 
Thryophilus sinaloa cinereus, new subspecies. —ASHY WREN. 
Sussp. CHar.—Similar to 7. szzaloa, but the bill stouter, the upper 
mandible dark instead of light horn color, the general coloring above 
deeper and browner, that of the underparts, especially the breast and 
sides, more ashy.

March 28, 1888; M. Abbott Frazar). Above dark sepia, the rump, upper 
tail-coverts, tail, and outer edges of the wing quills decidedly rusty; tail 
feathers with about twelve narrow, transverse, black bands, less than one 
third the width of the light interspaces, the terminal three broken and ill- 
defined, all the others sharp and distinct; outer two primaries with plain 
drab edges; outer edges of all the other wing quills with blackish, trans- 
verse spots or short bars about half the width of the tight interspaces ; 
superciliary line and throat white; middle of abdomen ashy white; both 
throat and abdomen with fine, indistinct, dusky spots sparsely distributed ; 
crissum and under tail-coverts white, barred heavily with black; breast

of wing and under wing-coverts white mottled with dusky; upper man- 
dible (in dried specimen) dark (slaty) horn color; lower mandible flesh,
