428 BIRDS OF AUSTRALIA. 



In structure and in the general disposition of its markings, 

 the White-breasted Ymch. offers a considerable resemblance to 

 the Bonacola castaneothoraco of the eastern coast, and in all

Crown of the head, all the upper surface, and wings delicate 

 greyish brown ; the tips of the wing-coverts very minutely

Total length 4^ inches ; bill \ ; wing 2^ ; tail if ; tarsi f .

 Bynoe, who procured it on the banks of the Victoria
