With the help of these properly sexed examples it becomes evident that 

 P. h. salvadorii, though easily distinguished by the colour of the upper- and 

 underside, has the ear-coverts asby slate in the adult male, more or less ochraceous 

 in the females. The colour of the ear-coverts is, therefore, not a distinguishing 

 character of this subspecies.

The females agree well with three from Arfak, except that they are somewhat 

 more whitish and less yellowish on the under-surface, and the wings mostly less 

 edged with rnfons. Probably our Arfak examples are less adult, but a series, also 

 of males, would be necessary from Arfak to decide whether the South-eastern form 

 is quite the same or not. 



It has beeu supposed that we knew the adult male, which was like the female, 

 but this is evidently not the case. Of the nine Arfak (Hatam) specimens which 

 Salvador! had when he wrote the (>>■». dilla Papuusia (vol. ii. p. 234), seven were 

 sexed as females. The two sexed as males are evidently immature, as they are 

 described as more rufous. Of the three before us one has no indication of the sex, 

 the others are marked as females (" parampnan "). The two birds sexed as males 

 by Meek differ very much in colour, but agree entirely in shape ami dimensions. 

 "We have therefore no doubt that they are the genuine males of Pachycephala 

 leucostigma, hitherto only known from females and immature males. 



The adult males are as follows : 



Upperside olivaceous brown, head greyish, the feathers being slate-grey with 

 olivaceous edges; quills deep brown, outer edges greenish olive-brown, paler on 

 the primaries, brighter and wider on the secondaries; rectrices olive-brown with 

 olive-green borders ; upper wing-coverts olive-brown, some of the median and 

 larger ones with pale brownish buff tips. Feathers of the throat dirty whitish buff, 

 tips narrowly edged with olive, bases dark grey ; breast and abdomen pale huffy 

 olivaceous brown, under tail-coverts washed with rusty rufous. Under wing-coverts 

 and inner lining of quills rusty buff.
