Three females from Arfak are above much mure brownish olive, the head 

 brown, whereas in birds from British New Guinea the upper parts are darker olive, 

 the head greyish brown. 



Fresh material should be compared from Arfak, in order to show if these 

 differences are constant enough to warrant the separation of two forms.

No. 2152 is quite a young bird. It is dark olive-green above with chestnut 

 patches, the rump still chestnut rufous, the rufous feathers evidently being those 

 of the first plumage, the olive-green ones that of the next, and the underside 

 uniform cinnamon rufous. No. 1909 is also young, being like the former on the 

 npperside, but having the underside, below the breast, mixed with dirty whire. 

 Neither has any nape patch, and iu one the forehead is tinged with rufous

This is the first time we have received specimens of this very rare Pachycephala. 

 The male in fresh plumage has the crown black, the back ashy grey, slightly 

 lighter on the rump. The underside, with the exception of the wide Mack 

 praepectoral collar, is white. In worn plumage the back is more brownish, and 

 the dark shafts of the feathers, which are less in evidence in freshly moulted birds, 

 become very conspicuous. The female, in fresh plumage, is grey above, without 

 any black on the crown, the throat white with black shaft-lines ; a band of grey 

 with blackish streaks across the lower throat, just before the breast : the abdomen 

 white with a creamy tinge ; under tail-coverts white. Wing, £, about 88 — 89 nun. 



We have now the following subspecies of this group : 



P. 1. leucogastra Salvad. & D'Alb., 1875 : British New Guinea. Mountains. 



[Wing, <S ad., 88 — 89 mm. ; back ashy grey ; sides of chest white ; abdomen 

 white; bill shorter. ¥: above grey; throat with dark shads; pale grey prae- 

 pectoral collar ; abdomen creamy white.]
