(leteriuiiuition of l)irds in immature plumage, since such individuals are 
frequeutly much smaller than adults. The dark grayish upper surface 
seems, however, to he a reasonahly certain means of identification. An 
example of Pinicola enucteator eschatoms in juvenal i)lumage, from 
Newfoundland, differs from the juvenal stage of Pinicola enucteator 
leucura iu its more grayish upper surface; the more greenish, less orange 
tint of tlie yellowish wash on the same area, jiarticularly pileum, rump, 
and upper tail-coverts; darker, more grayish wings and tail; darker, 
more brownish wing-hars; and more grayish sides of head and lower 
parts. 
A single immature male. No. 1(52,314, U. S. Nat. IMiis., taken at Pon- 
kapog, .Massachusetts, January 22, 18t)3, hy Mr. J. II. Bowles, is referable 
to Pinicola enuclealor eschatosus, and indicates that this form is to he 
looked for all along the coast region of northeastern North .\merica, from 
at least southern New England north to Newfoundland. 
.\ctual comparisons of the present new’ form have been made with 
specimens of Pinicola enuclealor leucura chiefly from Fort Chimo, Un- 
gava, in extreme northern (iuehec, but the latter is the common bird of 
all northeastern North .Vmerica, excepting, of cour.se, Newfoundland. It 
was originally described hy IMulleras Loxia leucura * * * § ami based on Buffon, 
with “ Canada” as the tyi)e region. This, as (Mssin has shown,t is in¬ 
tended to refer to Buffon’s (i. e., d’Auhenton’s) i)late of the ” (iros-Bec, 
(In Canada and also doubtless to his original descri})tion of the “ Dur- 
hec” or ‘‘ (iros-bec de Canada.Both de.scription and plate are un¬ 
doubtedly of the Pine grosbeak. Since the original of Button’s description 
and d’Auhenton’s plate came probably from the French portion of Canada, 
and since in view' of the subspeciiic separation of the New’foundland bird, 
it is desirable to re.strict Pinicola enuclealor leucura to a dettnite area, 
we desiiinate the city of Quebec as the type locality, a place where it 
uudouhtc'dly occurs at least iu winter.
