these respects. As there are no sexed specimens one cannot tell in 

 what respects, if at all, the sexes differ, but the probabilitj' is that 

 the smaller birds with the wing about 9'5 are females.

Adult male and female. General colour of the upper parts and 

 chest dark glossy olive-green ; the feathers of the fore part of the 

 head edged with greyish white, those bordering the sides of the head 

 and covering the cheeks similarly marked, the former making a rather 

 well-marked superciliary stripe ; feathers of the back of the neck, 

 mantle, and a few of the wing-coverts indistinctly bordered with 

 whitish grey, those of the fore part of the neck and chest margined 

 on the sides with white ; breast and rest of underparts rufous brown, 

 finely mottled with dusky, and slightly glossed with green on the 

 under tail-coverts. 



This species is very closely allied to P. ohscvra, from which, 

 however, it may always be distinguished by the grey-edged cheek- 

 feathers and the more marked grey superciliary stripes, which are 

 continued down the sides of the naked throat : it is readily distin- 

 guished from P. marail by the much lighter and greener colour 

 of the upper parts as well as by the rufous-brown belly. 



Male. Total length 29 inches, wing 11-5, tail 12-1, tarsus 2-8, 

 middle toe and claw 2-3. 



Female. Total length 26 inches, wing 10, tail 9-6, tarsus 2-3, 

 middle toe and claw 2-3.
