 present specimens add an enormous area to that occupied by ripponi.

If the birds from Sumatra always differ from those on the 

 mainland in having their flanks chestnut streaked, the latter will 

 have to be called Lophv/ro rufa castonea (Gray), and the Siam birds 

 would also come under this name.

Birds from Southern Burma and the Malay States agree in 

 beino- more richly coloured both above and below, and they gene- 

 rally also have a slaty-blue wash on the upper parts, more especial- 

 ly on the wing-coverts and inner secondaries, the latter of which are 

 in many specimens very strongly suffused with this colour. None 

 of the Indian birds, with the exception of one from Lucknow, has 

 any trace of this colour. 



The Siam birds are very richly coloured, and approach 

 E. c. lineata in this respect.
