A BRIEF REVIEW OF THE LAGOPODES. 91 



In rupestris the prepectus is never uniform blackish, but is, on the con- 

 trary, always distinctly barred. 1 



The Rock Ptarmigan inhabits Arctic America and is presumed to 

 be the form occurring on the Siberian tundras as far west as Yenisey.

This is the Eastern or Greenlandic race of the Rock Ptarmigan. So 

 far I can detect, this form offers the peculiarity that the females are easier 

 distinguishable from the mainland race tban the males. They are much 

 more narrowly banded, and present a much darker and less orange co- 

 lored appearance. 2 



It has been shown by Mr. Turner, that it is the Greenland Ptarmi- 

 gan which breeds at Gumberland Gulf, a conclusion which seems to me 

 fully correct. I have based my judgement upon the same material.

1 Mr. Turner 1. c. remarks that U. S. Nat. Mus. Nr. 34120 from Lapland and 

 No. 43686 from the Barren Grounds of Arctic America are identical in plumage. 

 The difference pointed out above is very plainly visihle, however. 



2 Tlie Greenland form has two very distinet summer-plurnages. Nr. 20317 

 (U. S. Nat. Mus.) the sex of which Turner (1. c.) doubts is reallj a male in the 

 finely vermiculated postästival plumage, and it i< iml killed in July, the label imli- 

 cating it as oblained in the «fall» (autumn).
