WILLOW PTARMIGAN. 
Lagopus lagopus. 
Lagopus lagopus alleni. 
Lagopus lagopus alexandre. 
In summer the male has the head and neck chest- 
nut, often becoming darker below. On the neck and 
chest this is often barred and flecked with black, as it 
is also on the flanks and generally on the under parts. 
The belly is more or less slate color. The quills and 
outer wing coverts are white and the rest of the upper 
parts irregularly barred with tawny, brown and black. 
Many of the feathers are tipped with whitish. The 
female is less deeply colored and is spotted with a 
paler tawny or yellow. The length is 14 to 17 inches, 
wing, 7 to 7)% inches. 
The Newfoundland form, known as Allen’s ptarmi- 
gan, is slightly different, and is described as having a 
few of the secondaries, quills and wing coverts more 
or less mottled with dusky, and the shafts black. But 
this difference may be only seasonal. 
Mr. Austin Hobart Clark, who reported on the birds 
collected and observed during the cruise of the ‘Alba- 
tross in the North Pacific, found in southern Alaska a 
new form of willow grouse, L. J. alexandre. It is 
somewhat smaller than the willow grouse of the North,
