210 ON GERYGONE- AND EURYLAIMUS=-SPECIES, 
Young birds of the subspecies harterti have the under 
taileoverts yellow, tinged with pale vinous. In the Leyden 
Museum are two young specimens and two older ones 
from Padang, W. Sumatra, which have such under tail- 
coverts. In a young bird from Goenoeng Kenepai, Borneo, 
which has still remains of the first plumage on the upper 
surface, the under tailcoverts are already vinous with only 
a trace of yellow. 
The black pectoral band is as a rule in old males 
broader and more distinct than in males from Java, but 
as my material is not very large, I can not say, whether 
this is a constant difference or not. Examples from Borneo 
have but small and indistinct pectoral bands. In size the 
two forms are not different.
