parts, and the sides of the head and neck, the ring round the eye, the lores, and the breast are tinged 

 with warm rufous-buff. Total length 7 inches, culmen 0'65, wing 3'9, tail 2 - 9, tarsus 1*1. 



Adult Female (Hamilton, Ontario, May 26th) . Resembles the male. 



Obs. The variation in measurements is in the males — culmen 055 to - 65 inch, wing 3 - 8 to 4'1, tail 2"7 

 to 30, tarsus 1-1 to 1"15 ; and in the females — culmen - 55 to - 65 inch, wing 3'55 to 3 - 85, tail 2 - 55 

 to 2 - 9, tarsus l'l to 1*15. There is some variation also in tone of colour, the eastern specimens being 

 browner, and the western ones clearer and darker in tinge. The Californian form, found west of the 

 Rocky Mountains {Turdus ustulatus), is scarcely distinguishable from true T. swainsoni, and differs 

 merely in being rather more rufous in tone of colour on the upper parts. 



This graceful little Thrush can be included only as a rare straggler to us from the American 

 continent. It is recorded as having been once obtained in Greenland, for, according to Professor 

 Bernhardt (J. f. O. 1854, p. 427), a specimen was shot in June 1845 at AmaragHk, in the 

 Godthaab district, and presented to the Museum by Governor Holboell. 



In Europe proper it appears to have been obtained on six occasions. One was, according to 

 Professor Giglioli (Ibis, 1881, p. 198), captured near Genoa in the autumn of 1843, and is now 

 in the Museum at Florence. This is the specimen figured by Durazzo. A second was purchased 

 in the market at Namur, Belgium, and is now in the collection of Baron de Selys-Longchamps, 

 where I examined it when on a visit to Baron de Selys some years ago. The third was captured 

 in Heligoland in October 1869, and is now in the Gatke collection. This specimen I have also 

 examined, and agree with Mr. Seebohm that it is rather less yellow on the throat than specimens 

 in my collection from North America, with which it was compared, but otherwise it agrees closely 

 with them. A fourth specimen was, according to Mr. Gatke (Vogelw. Helgolands, p. 251), 

 obtained in Holstein many years ago, and is now in the Hamburg Museum ; a fifth was, 

 according to Giglioli (Avifauna Italica, p. 101), obtained near Rovereto, Tyrol, in 1878, and is 

 now in the museum of that town; and a sixth is, according to Giglioli (Avif. Ital. 1889, p. 183) 

 in the collection of Prof. Magni-Griffi, and was obtained at Sarzana, in Liguria, but Prof. Giglioli 

 says that he has not seen this specimen. 



In America the range of this Thrush extends from the Slave Lake and Fort Yukon down south 

 to Ecuador and Brazil, and it has also been met with in Cuba and Costa Rica. Messrs. Baird, 

 Brewer, and Ridgway say (N.-Am. Birds, i. p. 14) that they have examined specimens from " the 

 Great Slave Lake, Mackenzie River, and Yukon to Guatemala; from the Atlantic States to East 

 Humboldt Mountains, Nevada, and from intervening localities. The extremes of variation are 

 the brownish olive of the eastern and clear dark greenish olive of the remote western specimens. 

 There is no observable difference between a Guatemala skin and one from Fort Bridger, Utah." 

 Messrs. Berlepsch and Taczanowski, who record it from Chimbo in Western Ecuador, remark 

 that a male obtained there in December appears to be more closely allied to Turdus ustulatus. 

 Mr. Taczanowski also records it from Central Peru. 



As will be seen from the above, this Thrush winters far south, but it is said to breed from 

 latitude 44° to the high Arctic regions. Messrs. Baird, Brewer, and Ridgway state (l. c.) that the 

 present species is common during the breeding-season in the neighbourhood of Calais, Maine ;
