wing-quills edged, and the coverts and tertials also tipped, with the

 yellow of the middle of abdomen; jugulum and breast paler buffy 

 olive, mixed with light yellowish; crissum dull cream buff, the centers 

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

 edge chamois; ''iris red; bill dull black, horn brown at base beneath;

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 

 sirnpex halizonus, since at that time no one separated these two 

 species. 



The following races of Pycnonotus brunneus are now recognizable:
