has apparently not been described. The feathers of the crown and nape are widely 

 margined with olive-grey ; throat white ; the feathers of the wide jngnlar black 

 land luive yellowish tips ; the feathers of the back are yellowish olive. Quills dull 

 black, primaries outwardly margined with grey, secondaries and npper wing-coverta 

 ■with dull olive-green ; tail black, mottled with olive-green. 



Wings only 80 mm., those of the males 85-88 mm. 



The males agree perfectly with those from the mountains of British 

 IJew Guinea.

The adult male was described by us in 1907, but it must be added that the 

 adult female has the crown almost uniform olive-grey, the forehead only being 

 adorned with white streaks. The very young bird (No. 5251), just from the nest, 

 agrees with other young, though older, birds. These birds are absolutely identical 

 with those from the mountaius of British New Guinea, but it is desirable to have a 

 good series of fresh Arfak specimens to compare.

Mr. Ogilvie-Grant distinguished his new form, stating that it differed from 

 ispecimens from the Aroa and Mambare Rivers in having the top of the head and 

 €ar-coverts very dark slate-grey like the rest of the upper parts, while in 

 P. poliosoma poUosoma these parts were washed with brown, and that the foreneck 

 and chest were uniform dark grey, not washed with brown. These alleged 

 differences are, we are sorry to say, not constant at all, when comparing the Snow 

 Mountain birds witli our twenty specimens from British Papna. Not only are the 

 alleged distinguishing characters of the birds from the Snow Mountains not equally 

 seen in all the specimens, but they are also evident in several adult males in fresh 

 plumage from British New Guinea.

These five specimens show the dark sliaft-lines to the feathers of the; underside, 

 especially of tiie throat, chest, and breast, very conspicuously ; in this resjxict they 

 are most nearly apjiroached by some of the birds from the Upper Aroa Uiver in 

 British New Guinea, but also some Am birds — Aru being the typical locality — 

 show distinct stripes, and our Aru examples being inferior skins, as compared with 

 those of Mr. Meek, a very close comparison is somewhat diflicult. it, appears,
