These examples appear to be all fully adult, and differ 
from each other only in the under tail-coverts, which are 
bright sulphur-yellow in some to almost white in others; the 
under w T ing-coverts vary in a similar manner. 
The wing-measurements of the males are 2*8-3'0 inches, 
females 2*7-2’95. 
[This species is quite common in wooded districts and has 
rather a pleasing call, with which different individuals answer 
one another. It is in this way that specimens of the bird can 
be most easily procured ; its habits of living in the thick 
parts of the trees, hidden in the foliage, would otherwise 
make it difficult to find, were it not for its call.— W. F.~\
