HYPOTHETICAL LIST. 757 
Wisconsin, even in the southern part of the state, but more often in the 
northwestern portion” (Bull. Wis. Nat. Hist. Soc. III, 1903, 124). No 
statement is made as to the authority for the identification of these speci- 
mens. If this form occurs in Michigan at all we should look for it in the 
extreme western part of the Upper Peninsula in fall and winter; the fact 
that Dr. Atkins’ specimens were taken in southern Michigan and in late 
spring increases our doubt as to the identification. 
Willow Thrush. Hylocichla fuscescens salicicola Ridgw. (756a) 
Synonyms: Western Tawny Thrush; Western Wilson’s Thrush. 
This is the western form of the Veery, differing but slightly from the 
typical form, but often decidedly larger and with the spots of the breast 
somewhat darker. It belongs to the Rocky Mountain region, ranging 
eastward regular to Dakota and more rarely to Illinois, Wisconsin, and 
probably to Minnesota. Specimens have been taken at Chicago, IIL, 
Grand Crossing, Tl., Liverpool, Ind. (Butler, Birds of Indiana, p. 1151), 
and a single specimen was taken at Delevan, Wis., May 6, 1899 and identified 
by William Brewster (Birds of Wisconsin, 1903, p. 126). Mr. P. A. 
Taverner of Detroit writes ‘I believe that Saunders has taken it at London, 
Ont. and Fleming at Totonto, Ontario. * * *- I believe that all 
specimens taken after September 15 or 20 can usually be referred to this 
form.”’? We have not had opportunity to examine any suspected specimens, 
but collectors should be on the lookout for this subspecies. 
Greenland Wheatear. Saxicola cnanthe leucorhoa ((mel.). (765a) 
This is a bird of striking plumage, and about the size of a common Blue 
Bird, native to Greenland, adjacent portions of North America, and Ice- 
land, but has been recorded also from Quebec, Ontario, New Brunswick, 
New York, and once or twice from New England, probably while wandering 
southward on its autumnal migration. 
There are no satisfactory records of the Wheatear in Michigan. 
“Archer” (G. A. Stockwell) says: ‘An occasional autumnal visitor to 
Sanilac and St. Clair counties” (Forest and Stream, Vol. 8, No. 16, p. 241), 
but cites no specimens. It is not improbable that it may occur at rare 
intervals, but we have no proof of its presence as yet.
