EVERMANN’S PTARMIGAN. 
alrite peculiarly marked and very distinct species has 
as yet only been obtained on Attu Island, one of the 
Aleutian chain, situated near the western extremity, and 
about 1400 miles from Unalaska. It may be restricted 
entirely to this island. There is no other Ptarmigan 
known to inhabit any portion of North America which 
can be mistaken for this bird,and it presents in its colora- 
tion but little resemblance to any of the other species. 
It was first obtained by Professor Evermann, and only 
nine specimens have as yet been procured. Little or 
nothing is known of its habits, which, however, doubt- 
less do not differ from those of other Ptarmigan.
