most perfect uniformity. The eighth lias onl)^ a trace of the 

 chestnut pectoral band, but its absence is probably clue to the 

 fact that the bird is either young or very immature, as is shown by 

 the dull, faded appearance of the black portions of the plumage, 

 by the paleness of the yellow of the underparts, and still more 

 conclusively by the light edging on some of the tail-feathers. 

 Among the fourteen specimens oi ivagleri examined, there is not 

 one vs^hich has any approach to a chestnut band, although a few 

 show traces of chestnut along the line of demarcation between 

 the black and yellow of the underparts, thus indicating the prob- 

 ability of intergradation at points where the two forms meet. 

 Typical vjagleri is represented in the National Museum collec- 

 tion by specimens from Tepic, Guadalaxara, Guanajuato and 

 Coahuilla. Hence, its range extends nearly half around the habitat 

 of castaneopectus. The latter is probably confined to the upper 

 slopes and table lands of the Sierra Madre of Chihuahua and 

 Sonora, where it is perhaps resident, for Mr. McLeod found it 

 in Chihuahua late in December. Both forms may be confidently 

 expected to occur as stragglers north of the Mexican boundary,

 without trace of a median stripe ; wings and tail nearly concolor with back. 



$ rt(^.*(No2i4i27, collection of W. Brewster, El Carmen, Chihuahua, 

 Mexico, June 3, 18S5; R. R. McLeod). Top of head dull chestnut, per- 

 fectly uniform on the crown, but with a few lighter colored feathers on the 

 forehead near the base of the culmen ; remainder of upperparts olive 

 brown, tinged slightly with pale chestnut on the nape, interscapulars and 

 wings, a few of the interscapulars with clove-brown shaft-streaks; wing- 

 coverts and tertials tipped with drab; sides of head and neck plain hair- 

 brown with a short, poorly defined post-ocular stripe of dull chestnut; 

 entire lower parts light wood-brown, lightest — approaching brownish 

 white — on the jugulum and abdomen, deepest — clayey — on the throat, 

 flanks, and under tail-coverts; a distinct, broad, but short, blackish stripe 

 on each side of the throat, bordered above by a maxillary stripe of the 

 same color as the throat; lores dusky, bordered above by a brownish 

 white stripe which starts at the nostril, and just above the eye is lost in 

 the darker (hair-brown) color of the sides of the head; bend of wing and
