It is a resident in Madagascar, but has once been obtained in the neighbouring island GeograpM- 

 of Mauritius (Grandidier, Ois. Madag. p. 646), and there is an example in the British Museum tion. 

 said to have been obtained on the Zambesi. 



Its chestnut axillaries and slightly forked tail proclaim its relationship to G. orientalis ; Nearest 

 so that we may regard it as the result of an emigration from Ceylon during the Post- 

 Pliocene Glacial Epoch, when the Oriental Region was overcrowded with birds driven out of 

 Siberia by the cold.
