oceiir in summer in the Himalayas^ but its nest lias not been 

 found there. The eggs from the Yenesei vary considerably, 

 some almost exactly resembling the ordinary type of the 

 Blackbird, whereas others are more like those of the Mistle- 

 Tlirush, but have the ground-colour of a deeper blue. In 

 size they vary from 1-08 to 1-15 by 077 to 084 in. The 

 eggs of a clutch in my collection received from Herr Tancre 

 closely resemble the first figure (fig. 9), but are larger, 

 measuring r.21 by 0'86 in. 



TuRDUs siBiKicus Pall. Siberian Thrush, (PL IX. 

 figs. 13-16.) 



Nothing appears to have been known respecting the nidi- 

 fication of this Thrush until the nest was found on the 

 Yenesei Kiver by Mr. Popham in 1895, at Toorukhansk 

 (lat. 66° N.). He there took several nests, but was in no 

 case able to jjrocure the parent bird in order to identify the 

 eggs. In 1897, however, he was more fortunate in this 

 respect, and was thus enabled to prove the authenticity of the 

 specimens taken in 1895, as the eggs of this Thrush are 

 readily distinguishable from those of any other of the species 

 breeding on the Yenesei. Moreover, it nests rather later 

 than the other Thrushes. The nest, he writes (Ibis, 1898, 

 p. 495), is " of the usual type, a rather untidy structure of 

 dry grass, built in the fork of a willow a few feet from the 

 ground, not so bulky as a Fieldfare^s, with a scanty wall of 

 mud and an inner lining of coarse dry grass. Four of my 

 clutches somewhat resemble eggs of the Mistle-Tlirusb, one 

 of which has the blue rather darker than the remainder ; in 

 another the eggs are very small and very pale bluish white 

 in ground-colour; one clutch has the ground-colour very pale 

 blue-green and is covered all over the surface of the shell 

 with minute reddish spots. The eggs measure from 1*02 in. 

 long by 078 in. broad to 1*18 in. long by 87 in. broad.-" 



Mr. Alan Owston of Yokohama has also obtained the 

 eggs of this Thrush in Japan at Fuji, Sagami Hills, and 

 Novikurayama, where it nests in cherry, pine, chestnut, and 

 gumi [Eleagnus umbeUata) trees at a height of from six to
