91. PlOCEUS CASTANOPS, sp. n. 



Male. — Head and underparts bright golden yellow, shading into 

 chestnut on the forehead ; cheeks, front of the ear-coverts, chin, 

 and throat chestnut, shading into black in front of the eyes, and 

 with a narrow black edging to the chin ; the brown of the throat 

 narrow almost to a point towards the lower neck ; back of the neck, 

 back, and scapulars uniform yellowish olive, slightly more yellow on 

 the rump ; wings brown, with all the feathers broadly edged 

 with pale olive-yellow ; tail olive-brown, with narrow yellowish 

 edges to the feathers ; under surface of the wings brown, the 

 coverts pale rufous buff, with a golden shade, and the inner 

 margins of the quills yellow. Bill black ; legs reddish brown. 

 Total length 5*6 inches, culmen 0'65, wing 2'8, tail 2, tarsus 0"9. 



Female. — Crown and nape nearly uniform dusky brown ; back 

 and scapulars more huffish brown, with large dark centres to the 

 feathers ; wings, rump, and tail as in the male, but not so bright ; 

 underparts brownish buff, paler on the centre of the abdomen. 

 Bill dark above, pale beneath. Total length 5'3 inches, culmen 

 0"5.5, wing 2".5, tail r8, tarsus 09. 



In form and size this new species much resembles P. ocularius, 

 but in no stage of plumage can it be confounded with that bird, as 

 it has no black stripes through the eye, and the broad pale edges of 

 the wing-feathers contrast strongly with the dark portion. From 

 P. xanthopterus it differs in its smaller size, in the more olive colour- 

 ing of the back and edges of the wing-feathers, and in the brown of 

 the forehead.
