All the specimens we have seen, seven in number, agree with 

 the type of V. koratensis in having white or butfy white under tail- 

 coverts. Gyldenstolpe (I., p. 71), under V. melaschistus intermedia, 

 records a bird from Koh Lak "having the under tail-coverts pure 

 slaty grey and exactly of the same colour as the rest of the under 

 surface". Grey under tail-coverts are apparently characteristic of 

 typical infermed la and it was because of this that koraieiisis was 

 proposed for birds with white under tail -coverts. 



Mr. W. J. F. Williamson has obtained an example from 

 Naihut, near Langsuen, Peninsular Siam, with a wing of 120 mm. and 

 pale greyish buff" under tail-coverts. It is possible that a bird from 

 Junk Seylon recorded by Mueller (B., p. 13) as Volvocivora avensis 

 (wing 115 mm.) is of the present species, in which case it is the most 

 southerly on record.
