but I did not succeed in shooting one until the 19th of June. 

 It was feeding amongst the dead leaves on the ground in a 

 dense birch plantation. It proved to be a fine male in adult 

 plumage. I made the following memorandum of the colours 

 of the soft parts : " Bill black. Iris dark hazel. Pupil 

 blue- black. Legs very light brown, yellower at the back of 

 the tarsus and on the soles of the feet." In lat. 68 my com- 

 panion assured me that he saw one of these very handsome 

 birds on the wing ; but I did not observe it myself after we 

 left the Koo-ray'-i-ka, nor did I observe it at all on the 

 return journey. It seems to be a very shy and wary bird, 

 and it is evidently a very rare Thrush in the valley of the 

 Yen-e-say '. Middendorff does not mention it ; but I heard of 

 it from a Polish exile at Toor-o-kansk' as ihe*Chor' -noi drohzd, 

 or Black Thrush. 



TURDUS ATRIGULARIS, Temm. 



I did not meet with the Black-throated Thrush until the 

 6th of August, in lat. 63, when I shot two birds in first 

 plumage, which puzzled me. Two days later, in lat. 61J, 

 I secured a third young bird, and was fortunate enough to 

 obtain the adult female also. The chestnut colour of the 

 wing-lining and axillaries of the young of this species serve 

 to distinguish it from the young of T. pilaris and T. obscurus. 

 In the young of T. iliacus the chestnut of the wing-lining 

 and axillaries is much deeper in colour, and extends onto the 

 flanks, whilst it is scarcely perceptible on the under tail- 

 coverts. 



RUTICILLA PIKENICURUS (Linn.). 



My sole authority for including the Common Redstart 

 among the birds of the Yen-e-say 7 is a fine skin of a young 

 Redstart in first plumage, which I shot on the 3rd of August 

 in lat. 66. The plumage of this skin agrees exactly with 

 that of the young in first plumage of our bird ; and since it 

 was found by Harvie Brown and myself in the valley of the 

 Petchora in about the same latitude, I see no reason for sus- 

 pecting my Yen-e-say' bird to be the young of any other 

 allied species, though it has not hitherto been recorded from 

 so far east.
