of the feathers light buffy olive; lining of wing cream buff, the outer

Although this new race of Pycnonotus brunneus is here described 
from a single specimen, it must be regarded without doubt as distinct. 
The type has been carefully compared with all of our large series of this 
species, from various parts of its range, and can not be matched by 
any other example. ‘This is, so far as the upper parts are concerned, 
one of the darkest and most greenish of the races of Pycnonotus 
brunneus; while below it is more grayish and more clearly yellow than 
any of the others. Thus it superficially very much resembles some 
of the forms of Pycnonotus simplex, but it is readily distinguished 
from all of these by its dark buffy crissum, red eyes, squamate 
pileum, and other characters. 
The type is in fresh plumage, but still shows evidences of molt 
among the contour feathers, rectrices, and remiges. Its proper wing 
length may therefore be even somewhat longer than above given. 
Doctor Abbott reports this species as common on Pulo Siantan at 
the time of his visit, but this may refer in part at least to Pycnonotus 
simpex halizonus, since at that time no one separated these two 
species.
