» It is difficult to draw a line between burmanica as represented by speci- 
mens from Siam and malaccensis and there is a large intermediate zone. 
With fair series before us it seems just possible to separate the two forms 
at the Isthmus of Kra. 
a In both North and South Sumatra birds inseparable from both malac- 
censis and javana occur. The Sumatran race seems in fact exactly 
intermediate and we recognize it because we have seen no ochraceous headed 
birds from the Malay Peninsula, or dark headed birds from Borneo.
