ReEMARKS.—The sixteen specimens secured by the expedition 
(Nos. 469-484) were all obtained on Admiralty Island, May 3 
to June 16. Two of them are full-grown streaked juvenals taken 
May 15 and June 15; four are adult females; four are ‘‘imma- 
ture’? males (that is, they are not fully red) ; and six are in the 
full bright plumage. All of the latter are like the type (which 
is one of them) in essentials; one (No. 478) shows an albinistie 
tendency in that there are many white feathers in the top of 
head and neek; at least three show a few wax-yellow feathers 
amone the orange on the breast and back. I cannot see that the 
females or young differ (except in smaller size) from correspond- 
ing plumages of the eastern bird examined. But the four ‘‘im- 
mature’? males are constantly yellower than any of the corre- 
sponding plumage in the eastern series examined. For instance, 
the rump, breast, top of head, m No. 473, is dull saffron yellow. 
Two of the ‘‘immatures’’ also show a sprinkling of the orpiment 
orange feathers characteristic of the adults. In the Grinnell 
collection are six more examples of the newly described form, 
taken at Sitka in the summer of 1896. Only two of these are 
males, and these are also in intermixed immature and adult 
plumages. 
Through Dr. C. W. Riehmond I have been furnished for 
examination by the United States National Museum a series of 
107 male American crossbills. After a deliberate study of these 
in comparison with the series from the Sitkan District, and tak- 
ing into consideration seasonal and individual peculiarities, I 
feel convinced of the existence of a geographic race in the Sitkan 
District. It may be remarked that Nelson (Rep. Nat. Hist. Coll. 
Alaska, 1887, page 173) was inclined to recognize a distinct 
Alaskan race of curvirostra, but on the basis of its diminutive
