Adult in breeding-j^ilurnage. Most nearly allied to typical P.Jluvi- 

 aiilis, the general colour of the upper parts being black and the 

 chest and rest of underparts dark smoky-bkck slightly mixed with 

 silvery white. As in P. phiViiijjensis, the dark patch on the chin 

 barely extends on to the upper part of the throat ; the chestnut on 

 the neck and sides of the head extends to behind the eye, but the 

 secondaries are brown with only the basal part of the inner web 

 white. Bill black, base of lower mandible lemon-yellow, this colour 

 e.\tending up towards the eye {A.li. Wallace). Total length about 

 y-o inches, culmen from feathers on forehead 0-S5-0-9, wing 4-4-2, 

 tarsus 1-4, outer toe and claw 1 -8. 



The British Museum does not possess any examples of this species 

 iu winter plumage. Two adult birds shot on the 11th May and 

 2;3rd November respectively are similar to one another, both being 

 in fully adult plumage. In the bird shot in November several of 

 the chestnut feathers of the sides of the head and neck are being 

 replaced, not by white winter plumage, but by chestnut, while 

 many new feathers of the upper part of the chest are dark smoky- 

 black, like the old plumage of the rest of the underparts. 



i am thus led to the belief that P. tricolor does not assume a 

 winter or non-breeding plumage like the rest of its allies.
