of whistle, and at others a somewhat pleasing and plaintive 

 medody ; but it has a singular habit of uttering, when flitting 

 from tree to tree, a succession of notes and half-notes, some of 

 which are harmoniously blended, while others are equally dis- 

 cordant. 



It is said by the natives to breed in September and October. 



The nest is suspended by the top to the extremity of a 

 branch, and is formed of threads of bark, small spiders' nests, 

 green moss, &c., all felted together with cobwebs and vegeta- 

 ble fibres, and warmly lined with feathers ; it is about eight 

 inches in length, pointed at the top and at the bottom, and 

 about nine inches in circumference in the middle ; the extrance 

 is a small round hole, about three inches from the top, with a 

 slight projection immediately above it. I did not succeed in 

 procuring the eggs. 



The sexes are alike in plumage. 



All the upper surface olive-brown ; wings brown, margined 

 with olive ; two centre tail-feathers brown ; the remainder 

 white, crossed by an irregular band of black and tipped with 

 brown, the band upon all but the external feathers so blend- 

 ing with the brown at the tip that the white between merely 

 forms a spot on the inner web ; lores blackish brown ; line 

 over the eye, throat, and chest Hght grey, passing into buff 

 on the flanks, and into white on the centre of the abdomen 

 and under tail-coverts ; irides light reddish yellow ; bill and 

 feet black.
