According to Taczanowski (Faun. Orn. Sibir. Orient. i. p. 305) its range extends to the 
southern Baikal region in Eastern Siberia, and it may nest to the north of that country. Dybowski 
and Godlewski have several times found it near the southern part of the lake during the spring 
migration, when it appears in the first days of April, either solitary or mixed with bands of 
T. ruficollis. In one isolated instance they noticed a specimen in the last days of March, but after 
the end of April all disappeared. 
Dr. Oustalet (Nouv. Arch. Mus. (3) v. p. 150, 1893) states that five specimens were obtained 
during the expedition of M. Bonvalot and Prince Henry of Orleans, viz.: a male at Kuldja, in 
| Chinese Turkestan, in September; two females in September at Tsanju, in the Tian-shan 
| Mountains ; a female at Aktarma; and another female іп October at Arkan оп one of the branches 
of the Tarim River. 
In his account of the scientific results of Przewalski's journeys through Central Asia, Dr. Pleske 
says that specimens were obtained by this celebrated explorer at several places, and he gives the 
following summary of Przewalski's observations on the species :—“ During the journey to Lob-nor, 
the Black-breasted Ouzel was found during the autumn migration in September 1876 in the valleys 
of the Kung and the Zanma, and in the middle of October on Ше Tian-shan, in the ravines of Ше“ 
Balantai-gol and Chaidu-gol. At the end of September a pair was seen on Ше Juldus. These 
Thrushes inhabited the wooded islands of the above-named rivers, and frequented the thick bushes 
Des ше | of Viburnum opulus and Crategus in flocks of from seven to twenty individuals. In the valleys of 
hes uw the Lower Tarim the species wintered in masses, and affected the districts in which the Eleagnus 
hing lt shrubs were plentiful, and on the berries of these they principally fed. In the spring, in the same 
nner Lng districts, the Black-throated Ouzels were observed only once or twice, and were tired with their 
ав on det migration-flight, as the majority had already retired to more northern regions to nest. During 
> parent ih the autumn migration the species was encountered in greater numbers towards the end of August 
t, chit, die and the beginning of September in the Talki Ravine, on the Ssairam-nor, and singly in the western 
y consider and mountainous parts of Dsungaria. 
“At the end of February 1879 Przewalski found four of these Thrushes near Saissausk, 
which were frozen up for some ten days during a severe and icy snowstorm. Тһе poor birds, 
finding no shelter on the open steppe, took refuge on the window-shutter of the post-house 
and were frozen to death. In March the species became common on migration near Saissansk 
and on the Ulufigur Lake, and also arrived in small parties ou the Urungu River and in the 
southern Altai. At the beginning of August, Thrushes, apparently of this species, were observed on 
"n migration on the Tian-shan Mountains, also in Zaidam in the first half of September, and in Northern 
| Thibet in the latter half of the same month. 
КҮТ” “In the spring of 1885 the first individuals were observed in April on the Tschertsch-Darja 
ЖҮ and in the Tschertschian Oasis. Оп the Chotan-Darja the autumn migration began іп the middle 
» | of September, and increased in volume at the end of the month and the early part of October. 
шше А certain number apparently passed the winter here.” 
қ It should be noted that Dr. Pleske, in the work above quoted, gives a minute account of 
шінші | hybrids between M. ruficollis and the present species; but in the large series of specimens procured 
| by the brothers Grum-Grzimailo on the northern slopes of the Eastern Thian-shan, and from the 
districts of Turfan, Hami, Kansou, &c., he was much surprised not to find a single hybrid (Mél. 
Biol. xiii, p. 291). 
In Central Asia, Severtzow states that the species breeds in Eastern Turkestan, where it also 
partially winters, but in Western Turkestan it appears in winter only. During the second Yarkand 
Mission many specimens were obtained. Dr. Stoliczka observes that the species was very numerous
