Pallas, but not the Тиғйив pallidus of Gmelin). А couple of days after I shot two more on 
the same ground. Ав soon as the forests were passable I made daily rambles, and almost always 
heard the song of this bird. Turdus dubius had gone further north to breed; but this species was 
evidently stopping and making preparations to build its nest. . . I did not meet with this interesting 
Thrush farther north than the Arctic Circle; but on my return journey, in lat. 66°, on the 3rd of 
August (and afterwards in lat. 63°, on the 6th of August) I shot the young in first plumage, with 
spotted backs and spotted breasts " (Ibis, 1879, pp. 4, 5). 
On his expedition to the Yenesei in 1896, Mr. H. Leybourne Popham did not succeed in finding 
the nest of this Thrush, and only obtained a single specimen on the Kamina Tungooska River (Ibis, 
1897, p. 92). On his third visit to the Yenesei, Mr. Popham was more fortunate, as he found three 
nests at Inbatskaya (lat. 64^ N.); but the species was not noticed at Yeniseisk (Ibis, 1898, p. 493). 
In Taczanowski's work on the birds of Eastern Siberia occur the following notes, summarizing 
the observations of the Russian naturalists on the present species.  Godlewski states that it is 
common in the neighbourhood of Lake Baikal and throughout the whole of Dauria, but is more 
plentifal in the former country than in the latter. During migration it associates with other 
Thrushes, especially with M. ruficollis, M. fuscatus, and М. naumanni, but it arrives much later 
than all the others, and does not put in an appearance till the latter part of May. А large proportion 
of these birds remain to nest in the southern part of the Lake Baikal region, commencing to 
build in the first half of the month of June.  Dybowski found the species much rarer in the 
Ussuri region than in Dauria. Dr. Radde observed the first pair on the ‘larei-noor on the 15th of 
Мау, 1856, and in the autumn the migration commenced during the first half of September, 
and the birds were most plentiful between the 14th and the 19th, while on the islands of the Onon 
River isolated individuals were seen up to the Sth of October. In the Boureia Mountains the 
chief passing of migrants took place on the 29th of September, when they followed the course 
of the high forests skirting the Amur River. In the autumn of 1857 the migration commenced on 
the 7th of September, and was at its height between the 19th and 21st of that month. 
According to Dr. Dybowski, it is the commonest Thrush in Kamtchatka, arriving there at the 
beginning of May, the young being able to fly at the end of June. Dr. Stejneger obtained specimens 
on Bering Island in June. He says that they visit the island in the spring, but without any regularity. 
In 1883 the first was observed on one of the first days of June, and during the week between 
the 10th and 17th of the same month two males and four females were secured ; they were extremely 
shy and always met with singly. 
` The species does not seem to have been noticed on the Kuril Islands, but must undoubtedly 
occur there. "The Seebohm Collection contains two examples from Yokohama (Pryer) and Nagasaki 
(Ringer), but it was supposed by Blakiston (Amended List B. Japan, p. 26) not to occur on the 
northern island of Yezo. А specimen procured at Hakodate by Mr. Henson is, however, recorded 
by Dr. Stejneger (Pr. U.S. Nat. Mus. xv. p. 317), who observes :—* The scarcity of the Eyebrowed 
‘Thrush in the northern portions of Japan is very remarkable, when we consider that it is common in 
Kamtchatka.” 
In his ‘Birds of the Japanese Empire’ (р. 49), Mr. Seebohm remarks that it is a very rate 
winter visitor to Japan. Two examples were in the Pryer Collection from Yokohama (Blakist. & 
Pıyer, Tr. As. Soc. Japan, 1882, p. 166). He also records an example in the British Museum, 
obtained by Capt. St. John near Nagasaki. Jouy writes (Pr. U.S. Nat. Mus. vi. p. 917, 1888) that 
it was rather rare at Tate-yama, and appeared to visit Shinshiu only in the autumn. It was 
generally found about streams and in thickets, and a few were caught on the hills by the bird- 
catchers.
