specimen is Henson’s No, 90, collected near Hakodate, June 20, 1884, 
and determined by him to be a female. The only difference is, that the 
throat is slightly suffused with the tawny of the breast, but there is no 
trace of dusky or dark brownish on chin, throat, or jugulum. Nor have 
I found it otherwise in any of the eastern specimens before me desig- 
nated as females. On the other hand, the only European female P. 
rubicola betore me (U.S. Nat. Mus., No. 18751) has the chin, throat, and 
upper jugulum brownish black with narrow pale margins to the feathers, 
Naumann, moreover, on plate xe (Naturg. Vég. Deutschl., 111), and 
Dresser, on plate xl (Birds of Eur., 11), likewise figure the adult females 
as having the parts named more or less blackish brown, and so deseribe 
them. In Yarrell’s “British Birds” (4th ed., Newton, 1, p. 343) the adult 
female is described as having the “chin buff, throat blackish.” These 
descriptions and figures refer to the breeding plumage, for after the 
autumnal molt the light margins to the feathers of the throat are so 
broad as to totally or nearly totally conceal the blackish base; and 
females in this plumage (November) are described by Macgillivray 
(Hist. Brit. Birds, 11, p. 281) as having the throat “light grayish brown.” 
The blackish on the throat, therefore, only appears in spring, when the 
margins become worn towards the breeding season. But it will be 
observed that the females of P. maura, which I have referred to, are 
in the most possibly abraded plumage, their throat feathers being light 
colored down to the plumbeous bases. 
And as with the adult females, so with the young males. Several 
specimens so marked by the collectors (U.S. Nat. Mus., No. 86123; and 
Jouy’s Corean examples) have the throat uniform buffy in the first 
autumnal plumage, with noDlack atthe base, and Henson’s No. 782, col- 
lected in June, and in a wretchedly worn plumage, has the throat quite 
as whitish as the females quoted above, being in every respect a coun- 
terpart of them. The young P. rubicola, on the contrary, appears to 
assume at once a plumage which is but slightly different from the old 
males (Naumann, tom. cit., p. 888), with the throat more or less blackish.
