Dendroica coronata hooveri McGregor. 
Alaska Myrtle Warbler. 
This species was found only at Windfall Harbor, Admiralty 
Island, where two specimens, an adult male (No. 308) and an 
adult female (No. 309) were taken by Stephens and Littlejohn, 
respectively. These two examples show the following measure- 
ments: 
Wing Tail 
Male 75 66 
Female 71 61 
A color character of this form was pointed out by Bishop (N. 
Am. Fauna, No. 19, 1900, page 90) and holds in the six Alaskan 
males I have at hand, as compared with eastern birds; that is, 
the black on the chest is distributed more narrowly on each 
feather so as to give a streaked rather than a clouded effect. 
The larger size also is diagnostic. This subspecies was based 
on migrants and winter birds taken in California. (See Me- 
Gregor, Bull. Cooper Orn. Club, I, 1899, pages 32, 33.) 
Dendroica townsendi (Townsend). Townsend Warbler. 
At Windfall Harbor, Admiralty Island, several Townsend 
warblers were seen during a storm on May 13, and an adult male 
(No. 300) was secured by Littlejohn. At Red Bluff Bay, Ba- 
ranof Island, in June, Stephens saw a male at close range, but 
had no ‘‘aux’’ at the time. A full-plumaged male (No. 328) 
was shot by Hasselborg at Glacier Bay, July 9. It was acting 
as though a nest were nearby. 
Wilsonia pusilla pileolata (Pallas). Pileolated Warbler. 
This warbler became moderately common at Windfall Har- 
bor, Admiralty Island, early in May. Four adult males (Nos. 
341-344) were obtained there by Stephens and Littlejohn, May 
8 to 13. At Coppermine Cove, Glacier Bay, Dixon found the 
species common in the alders July 11, and secured an adult 
female (No. 351). These five skins are typically pileolata, show- 
ing all the characters separating that form from both pusilla 
and chryseola, as carefully pointed out by Ridgway (Bds. N. & 
Mid. Am. II, 1902, pp. 712-714).
