* Material from Siberia being very meagre, I have principally determined 

 this form from the considerable number of large and long-tailed birds, always 

 on the pale side, existing in collections from Cevlon, Intlia, Assam, etc., which 

 are obviously migrants from the north, and have no connection with the 

 smaller and darker form breeding in N. India [C. t. saturata), with the rather 

 darker but nearly typical bird breeding in W. Asia, or with the darker but 

 large race breeding in Japan (C. /. japonica). .\ large immature ^ bird in 

 my collection from Ceylon has a tail measurement of 7.75 in. and there 

 are birds in the Tring collection with nearly the same measurement.
