WILLOW PTARMIGAN. 



Lagopus lagopus. 

 Lagopus lagopus alleni. 

 Lagopus lagopus alexandra. 



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. I. alexandra. It is 

 somewhat smaller than the willow grouse of the North,
