 &634. 



Iris brown ; bill and feet slate-blue. 



In this species the plumage of the sexes appears to be 

 quite alike, but the males are somewhat larger, on the whole, 

 as the following measurements will show. 



In eight males the wings measure : — 79 ; (2) 80 ; 81 

 (2) 82; 83; 85 mm. 



In eight females the wings measure: — 75; (3) 76; (2) 

 77; (2) 78 mm. 



Young birds have the upper part of the breast pale rufous- 

 buff and the sides tinged with the same colour. In this 

 plumage the species was described by Gray from the Aru 

 Islands as M. griseogxdaris. 



In the British Museum there is an obviously immature 

 specimen procured by J. M. Dumas in North New Guinea, 

 probably in the vicinity of Humboldt Bay, which has been 

 referred to this species. It resembles the young of M. guttida 

 in all points except that the upper breast is bright reddish-
