There is hardly anything to add to the original description, though the colour 

 of the upperside is browner in some, darker and more blackish in others. Thfr 

 species is not quite a typical Pachycephala ; it approaches, in fact, the genus- 

 Pinarolestes, in the copious and fluffy plumage on the back and rump, but the bill 

 is mnoh deeper, in fact exactly like that of other typical Pachi/cephalac. 



Wings of the males 93-96, females 90-92 mm.

The curious plumage of the young birds aud the differences from P. r. rufinucha 

 have been described as quoted above. This species approaches Pachycephala 

 tenebrosa in the fluffy plumage of the back and rump, thus connecting it with the 

 true Pachycephala.

The first plumage in which these birds leave the nest has apparently not yet. 

 been described ; the immature specimens have cinnamon edges to the quills and 

 upper wing-coverts, and a few cinnaraon-riifous feathers on the back .and abdomen, 

 showing that the foregoing plumage must have been cinnamon-rufous. Their heads. 

 are dull cinnauioneous-brown.

It is interesting to find on Mt. Goliath — as in several other cases — the Arfak 

 race, and not the one inhabiting British New Guinea.

" Iris chocolate-brown ; bill black ; feet slate-colour." 



The adult males vary somewhat in the colour of the back, which is sometimes 

 brighter, sometimes paler, and in a few cases washed with olive. More conspicnoiis^ 

 however, are the variations of the throat, which has in some specimens only a tiny 

 white spot, while in other specimens nearly the whole throat is white. The femal&
