The Magpie Robin inhabiting the North of Siarn belongs to the same race which 

 is found in India and Assam. It probably also occurs in the whole of Burma and Tenas- 

 serim. From its nearest ally C. s. musicus Raffl., which is a more southern form inhabiting 

 the Malay Peninsula, Sumatra and parts of Java, it is separated by having pure white axil- 

 laries. In C. s. musicus the axillaries are black with only a whitish tip to the feathers. 



The northern race seems, however, to interbreed with the southern form and the 

 specimens obtained at the neighbourhood of Koh Lak in the Siamese Malaya are practi- 

 cally intermediate and ought to be named 



Copsychus saularis saularis . ' musicus.
