collected in Dutch New Guinea. 173 



Young. Iris brown ; bill sooty-brown, gape pale yellow ; 

 feet and toes pale yellow. 



The type of this species was collected by Wallace in the 

 Aru Islands and is preserved in the British Museum. 



Birds killed in September are in worn plumage, by early 

 November they are nearly clean moulted, and, with one 

 exception, all examples in the above series are in full 

 plumage by the end of that month. 



A young bird of this species resembles the young of 

 M. Jlavigaster, described by Sharpe in the ' Catalogue of 

 Birds.^ The upperparts, including the top of the head, are 

 brown with light brownish- white tips to the feathers, the 

 back being interspersed with the dark olive-green plumage 

 of the adult ; the ear-coverts and cheeks are pale brown with 

 a distinct whitish ring round the eye ; the throat and middle 

 of the breast and belly are white ; the chest and sides of the 

 body brown, like the upperparts, and with pale spots at the 

 tips of the feathers. A few yellow feathers of the adult 

 plumage are making their appearance at the base of the 

 throat and on the middle of the chest. 



"Asa rule, this Olive and Yellow Flycatcher was seen 

 singly in the lower branches of the taller trees, and was by 

 no means easy to distinguish amongst the thick yello\>i!-h and 

 greenish foliage." — C. H. B, G.

I cannot separate this individual specimen from typical 

 M. flavigaster Gould, from Port Essington, though the yellow 

 on the middle of the breast and belly is perhaps a little 

 paler. The North Queensland bird, which has been separated 

 as M. f. terrceregince by Mr. Mathews [c/. N. Z. xviii. p. 303
