collected in Dutch New Guinea. 221 



They have the under wing-coverts scarlet. Mr. Rothschild 

 and Dr. Hartert record a young specimen of C. scintillatus 

 obtained by A. S. Meek on the Upper Setakwa River, while 

 from the Island River they record C. s. chloropterus obtained 

 by the same collector. On the Noord River, which occupies 

 an intermediate position between the two rivers mentioned 

 above, Dr. Lorentz collected a series of birds which Dr. van 

 Oort informs us are partly referable to typical C. scintillatus 

 and partly to C. s. cliloropterus, while some are intermediate. 

 This is very interesting, as it is evident that the two forms 

 overlap at this point. 



C. scintillatus, like many other Parrots, presents consider- 

 able individual variability in plumage ; there is no variation 

 met with among males which cannot be found among females 

 also. 



The principal points of variation are :— 



1. The yellow area on the basal half of the inner web 



of the primaries, which normally covers the outer 

 half of the web, may be much reduced and paler 

 in colour, showing an approach to the eastern 

 C. s. chloropterus. In some examples of the latter 

 subspecies the yellow is vestigial. 



2. The axillary plumes may be scarlet, or scarlet with 



a median shaft-stripe of green^ or even green with 

 red margins. 



3. The yellow shaft-streaks of the mantle and under- 



parts also show great variation ; in some examples 

 they are yellow^ in others those on the mantle and 

 belly are green and the yellow streaks are mostly 

 confined to the breast. In one young male the 

 feathers of both the mantle and breast are streaked 

 with orange-red ; while in a second example the 

 streaks on the mantle are green and those on the 

 chest orange-red, the feathers being tipped with 

 the same colour. 



The young males have the head brownish-black tinged 

 with purplish (not chestnutj as stated by Count Salvador! in
