" Miiller's Flycatcher was only observed on the stony 

 upper reaches of the rivers, where it was seen in parties of 

 from four to eight individuals, either flitting up and down 

 over the rushing water or sitting on the rocks and over- 

 hanging branches. It was one of the most attractive and 

 delightful objects on those almost lifeless rivers. Its call- 

 note is a pretty ' ziwit,' and its habits and actions were 

 much the same as those of the Common Flycatcher." —

The types of this species collected by Wallace in the Aru 

 Islands are in the British Museum. 



The iris is variousl}^ described as dark, red-brown, russet, 

 crimson, and inner ring red, outer yellow ; bill black ; feet 

 pale brown to purplish-fleshy. 



Individuals from Parimau, Canoe Camp, and Launch Camp, 

 killed in October, November, and December, are in moult ; 

 while some birds obtained during the same months are in 

 worn plnmage, and have not commenced to change ; others, 

 again, are in freshly-moulted plumage. It would thus 

 appear that the time of moulting is very irregular.
