Fastern Siberia, and he thinks that the species must migrate to China by another route, by Mongolia 
and also by Chinese Manchuria." 
Dr. Pleske gives the following note on M. ruficollis in his account of Przewalski's expeditions 
(Wiss. Result. Reis. Przew. Zool. ii. p. Т):--“То sum up the traveller's copious notes, M. ruficollis 
was not found nesting in any of the distriets traversed by him. Its winter-quarters were determined 
as being in Alashan, but to all the other countries it was a spring and autumn visitor, with the 
occasional exceptions of the upper course of the Chuanche River and the province of Gan-su. In 
the latter country four specimens were procured by Berezowski (see Bianchi, * Aves Exped. Potan. 
Gan-su, p. 101, 1891). Przewalski's specimens were procured by him on the Upper Chuanche, the 
country of the Urots in the Southern Gobi deserts, in Kuku-nor, Lob-nor, Alashan, and Zaidam 
(cf. Pleske, €. с. р. Т). He met with it everywhere during his first journey through Mongolia, 
with the exception of Lake Halka and Northern Thibet, but always on migration (Taczanowski, 
Ге. 
Von Middendorff, as quoted by Taczanowski, gives the following dates :—The first birds of this 
species were met with in the neighbourhood of Amingskaia-Sloboda at the end of April. In the 
Stanowoi Mountains (60^ N. lat.) large troops passed in the first half of May, and the migration 
was over before the end of the month, when they began building their nests in the chains on the 
western slope, while T. fuscatus had entirely disappeared. Middendorff further states that on 
approaching the crest of these Stanowoi Mountains no Thrushes were to be seen, and it was only 
on the southern shore of the Sea of Okhotsk that some were noticed between the 18th of September 
and the 22nd of October, in bands, but at such a distance that the species could not be distinguished. 
According to the same observer, the Yaconts give the name of Pine-Thrush to M. ruficollis, and 
Larch-Thrush to M. fuscata (Таса. Faun. Orn. Sibir. Orient. рр. 303, 504). Kalinowski did not 
meet with this Thrush in Corea, nor has it been recorded from Japan. 
Three specimens are recorded by Prof. Oustalet as having been obtained by M. Bonvalot and 
Prince Henry of Orleans—one on the Kansi-Daria on the 13th of October, 1889, at So and Tchoungo 
in Thibet, in April 1890, while another specimen was presented to the travellers by the missionaries 
at Ta-tsien-lou (Oust. N. Arch. Mus. (3) v. p. 143). Неге Mr. A. E. Pratt also met with the species, 
having previously obtained it at Ichang on the Upper Yangtze. 
Abbé David says that M. ruficollis passes along the mountain-regions of China in great numbers 
on migration. Although rare at Pekin, it abounds in Sichan, Mongolia, Shen-si, Moupin, and the 
other central provinces (David & Oust. Ois. Chine, p. 156). Dr. Oustalet (0. c.) mentions a 
specimen having been sent to the Paris Museum by Abbé Desgodins from Yer-ka-lo on the Upper 
Mekong River. 
Though not recorded as yet from any part of Burma, it will doubtless be found occasionally 
on some of the frontier hills or on the Pegu plains, and a single example was shown by 
Davison to Capt. Kelham as having been obtained at Singapore (Ibis, 1881, p. 510). This was 
evidently not the specimen of M. naumanni shot on Singapore Island on the 24th of June, 1817, 
which is now іп the Hume Collection, and is properly identified as that species. 
Colonel Godwin-Austen has procured this Ouzel on many occasions in the Naga and Miri 
Hills, as well as at Cherra Poonji (J. A. S. В. xxxix. pt. 2, p. 102). Mr. Hume (Str. F. xi. p. 129, 
1888) says that he never saw the bird on either the eastern or western hills of Manipur, but 
he shot several in the Manipur basin. Не found it solitary and not in parties, like Jf. atrigularis, 
always in the level country, feeding in the open ground, and, in Sylhet and Cachar, always where 
heaps of manure had been thrown down in the fields, about which heaps it was busily foraging. 
He continues:—* I have this species from Sadiya and many other places in the Dibrugarh district,
