from Glacier Bay are precisely alike and in full juvenal plu- 
mage, except for traces of natal down on the throat, and white 
feathers of the succeeding plumage in the wings. As compared 
with two birds in the Grinnell collection (Nos. 3864, and 3865 
from Kotzebue Sound) of exactly the same size and stage of 
plumage, the former show conspicuous differences. The whole 
dorsal surface is much darker, due to a spreading of the black 
as in the ease of the adults, while the barring and edging is deep 
hazel instead of buffy. Beneath, the young of alexandrae are 
heavily and closely barred with black even to the flanks. The 
ground color of the breast and sides is tawny, paling to dusky 
white on the belly. 
This new species is named for the courageous organizer and 
leader of the expedition, Miss Annie M. Alexander, to whose 
energetic supervision much of its success was due. 
Stephens records that at Bear Bay a man named Strassel 
shot four out of six ptarmigan seen; they were shot with soft- 
point balls, and but two were saved. At Hooniah, Chichagof 
Island, where Stephens shot No. 373, June 25, Dixon records 
that white ptarmigan feathers and droppings were found in 
almost every clump of hemlocks near the summit of the moun- 
tain. Another was seen to whiz off down the steep slope, and 
a male was heard calling. But the freezing mist was so thick 
that the bird could not be found, although it may have been 
within gun range. Dixon also records that at Coppermine Coye, 
Glacier Bay, July 10 to 20, the feathers and bones of a ptarmigan 
were found near a nest of broken eggs on the summit of the 
mountain, 2100 feet. The nest was under a stunted hemlock. 
All the feathers were white, so the ptarmigan must have laid 
early. Littlejohn’s notebook contains the following in regard to 
the Alexander willow ptarmigan found by him there: ‘‘ While 
searching for eges of the glaucous-winged gull on one of the 
small islands on the east side of Glacier Bay on July 14, I sud- 
denly came upon a flock of ptarmigan in a little opening among 
some spruce, hemlock, and alders, which covered the ground in 
dense masses in spots; the remainder of the area supported a 
thick growth of grass interspersed with patches of moss and low- 
growing flowering plants. There were about eighteen birds all
