from Phum-Liu near Kompong-thom in Cambodia; and. 
Mr. E, C. Stuart Baker has kindly given me information 
about ten others from Siam in the British Museum, col- 
lected by Messrs. Herbert, Barton, Flower, and Williamson. 
Probably the Orioles from the Chindwin Hills belong also 
to O. 1. thaiacous. 
The following notes have been received oo Mr. E. C. 
Stuart Baker :—— 
- Inarecent article in ‘ The Ibis’ (1918, p. 232) Mr. Boden 
Kloss has identified the Siamese form of Garrulax moniliger 
as mouhoti of Sharpe, whereas in the Bull. B. O.C. of 1917, 
p- 8, I gave the Siamese form a new name, leucotis. At the 
time I wrote this the three birds from Cambodia to which 
Sharpe originally gave the name mouhoti could not be found, 
but they have now been discovered, and are undoubtedly 
the same bird as that found in Siam. My name therefore 
becomes a synonym of mouhoti. 
On the other hand, I find that the Siamese bird is not the 
same as the Burmese bird and that the latter will require a 
new name. . There are therefore three Dele ee forms of 
Garrulax moniliger.

white patch in centre, General plumage pale, and chestnut
