We have already expressed our opinion (Ac.) that the specimens with the 

 auricular patch of olive are females. The yonng birds evidently also have this olive 

 patch, thus resembling the adult females. If our theory about the sexes is correct, 

 then we must, however, admit that many of our examples — even those " sexed " by 

 good collectors — are incorrectly marked, but nevertheless we are inclined to think 

 that we are right in this case.

It would be necessary to compare a series from the Arfak Mountains to decide 

 whether the form from the Owen Stanley Range differs from that of Arfak. The 

 one female we were able to compare from Arfak has the feathers of the crown tipped 

 with chestnut, while in those from Owgarra these tips are much lighter rufous. 

 There is, however, a good deal of variation in the colour of these feathers, but still 

 more in that of the abdomen. While the abdomen in most specimens is heavily 

 spotted — each feather having a light yellowish brown, almost buff, centre and a 

 blackish border — it is almost uniform yellowish brown in some evidently very old 

 males. Doubtless the most heavily spotted female (No. A 2601, from Bihagi, 

 12. viii. 06) is immature, and so is apparently our Arfak example.
