Sp. Char. — Adult : Ground-color ol' the plumage ochraceous-buft" ; but this densely mottled and 

 finely sprinkled above with reddish l)ruwn and blackish, the latter color prevailing on the dorsal 

 and scapular regions, where the feathers have lighter edges, the buff prevailing on the wing- 

 coverts, where the variegation consists of a finer and sparser sprinkling of the dusky and brown ; 

 on the tertials and ends of the secondaries, the reddish (a sort of cinnamon shade) forms the 

 ground-color, and is thickly sprinkled with irregular dusky dottings and zigzags ; pectoral tufts 

 nearly uniform dark brown, the feathers with broad lateral borders of clear yellowish ochraceous. 

 Pileum, rusty brown, darker anteriorly, changing gradually backward into the greenish olive-gray 

 of the nape ; sides of the head and neck yellowish ochraceous ; a malar stri[)e of dark ferruginous, 

 changing posteriorly into a very conspicuous stripe of blue-black (or in some specimens dull 



grayish) down each side of the neck ; chin and throat white, with a very narrow medial dusky 

 streak, suffused with ochraceous ; foreneck pale buff, with sharply d(;fined stripes of cinnamon- 

 brown edged with a black line ; lower parts pale buff, with narrower lirownish strijjes ; tibiae and

 browni.sh, this encircled narrowly with black ; legs and feet bright yellowish green ; claws pale 

 brown, dusky toward points.^ Yoiimj : Simihir to the adult, but more reddish, the mottling coarser, 

 and with a tendency to form ragged transverse bars, especially on the posterior ujiper parts.

In the large collection of specimens of this sj^ecies which we have been able to examine and 

 compare are certain variations of plumage and proportions, which appear, however, to be chiefly, 

 if not entirely, of an individual and seasonal character. The most apparent difference as to colors 

 consists of a more reddish .shade to tlie plumage in autumnal birds, while those olitained in the 

 s]iring or summer are characterized by a more grayish aspect. There is also another noticeable 

 difference between specimens, namely, in the distinctness of the black or dusky stripe along the 

 side of the upper neck. This is usually a deep glossy black ; but in many individuals it is
