The Siberian Ruby-throated Robin is a summer visitor to the 

 Kurile Islands (whence I have an example collected by Mr. Snow in 

 June) and to Yezzo (Seebohm, Ibis, 1884, p. 182). There is a single 

 example in the Pryer collection from Yokohama, and Mr. Ringer 

 obtained it near Nagasaki, where the examples procured by the 

 Siebold Expedition were probably obtained (Temminck and Schlegel, 

 Fauna Japonica, Aves, p. 57). It has been recorded from the 

 southern group of the Loo-Choo Islands (Stejneger, Proc. United 

 States Nat. Mus. 1887, p. 406). 



This fine songster breeds in Siberia from the Ural Mountains to 

 Kamtschatka, and winters in South China, the Philippine Islands, 

 Burma, and India.

The Siberian Blue Robin is a summer ^dsitor to Yezzo (Seebohm, 

 Ibis, 1884, p. 182), but probably does not winter there. In the 

 Pryer collection there are four males and a female from Fuji-yama, 

 where it breeds (Jouy, Proc. United States Nat. Mus. 1883, p. 281). 



This species is a summer visitor to East Siberia from Lake Baikal 

 to the mouth of the Amoor. It winters in China, Burma, North 

 India, the Malay Peninsula, and Borneo.
