nose. Then there is a single or double first note followed by a long 

 Veery-like vibration, sweet yet mournful. As would be expected, 

 the song is not noticeably different from that of Bicknell's Thrush 

 as heard in the White Mountains of New England and does not, as 

 has been stated, resemble that of the Hermit Thrush. 



We obtained only one specimen of this species, a worn female at 

 Cape Charles in July. The measurements of this specimen which 

 are as follows: wing 92 mm., tail 64 mm., bill 14 mm., tarsus 24 

 mm., correspond to those of a large Bicknell's Thrush or a small 

 Alice's Thrush. A series of specimens from Labrador might throw 

 interesting light on the standing of Bicknell's Thrush. 



Hylocichla ustulata swainsoni (Cab.). 

 Olive-backed Thrush. 



Common summer resident in the interior and on the southwestern 

 coast. 



Specimens were obtained by Drexler at Rupert House on June 13th 

 and in July, 1860. Low says that it was very common along the 

 upper Hamilton River; it was seen May 16th and eggs were found on 

 June 30th. A set of four eggs was taken on the Hamilton~Eiver on 

 July 3, 1894. Spreadborough observed it as far north as Fort George, 

 James Bay, in. June, 1896. 



We did not observe the bird but our observations extended but a 

 short way from the Arctic coastal zone. It is a bird of the Canadian 

 zone pushing its way in places into the Hudsonian zone. 



Hylocichla guttata pallasii (Cab.). 

 Hermit Thrush. 



Common summer resident in southern part. 



The Bowdoin college expedition brought back a specimen of this 

 thrush from Chateau Bay taken July 14th and there is another in the 

 Bangs collection from Lance au Loup taken June 1, 1899. Low says 

 it is "not rare at Lake Mistassini." Spreadborough says he observed 

 it only twice, on July 4th and 24th, 1896, in the interior of the penin- 

 sula.
