It is very interesting that at Gigalowa, where, according 

 to Mr. Hall, the fauna changes, the more southern form 

 (M. a. baicalensis) is found, while at all the more northern 

 places it is replaced by M. a. ocularis.

Motacilla flava taivana breeds in parts of Siberia and 

 winters in Formosa, South China, Malacca, &c. Probably 

 it represents M. flava borealis in the more southern parts 

 of Siberia, and might be regarded as a subspecies of the 

 y/ava-group.
