in the latter locality since 1893. Splendid set of 2 eggs, one larger and more heavily marked than the 
other. I found a nest of the Bristle Bird at Flat Rock, Middle Harbour, near Sydney, on 16th Sep- 
tember, 1903, but only after patiently watching the birds for two hours. It was constructed of grass, 
and placed about eighteen inches from the ground in a clump of the large-leaved Swamp Banksia 
(Banksia latifolia.) The nest was just finished and ready for eggs, and I revisited the place again seven 
days later, but was much disappointed to find that a bush fire had in the meantime passed over a large 
area of the country there, and carried away with it my rare nest, and no doubt also a fresh set of eggs. 
Fortunately I photographed the nest during my first visit, which picture accompanies this description. 
The black dot on the top of the white cross points to the opening in this dome-shaped structure. 
Within twenty yards of the Bristle Birds’ 
nest I took a splendid set of Emu 
Wrens’ (Stipiturus) eggs on the above 
date ; it was fortunate that it contained 
eggs, and that I had not to leave it 
also for another week, for had I done 
so it certainly would have been burnt. 
For this latter set see data No. 53. [

Dorrigo Scrubs, Upper Bellinger River 
district, N.S.W., on 12th October, 1898, by L. Vesper, Frank and Sid. W. Jackson. This is a beauti- 
fully zoned set of 3 eggs, but not so dark in the ground color as the previous set, No. 141. The eggs 
and nests of this species are both comparatively large, and the latter, which are dome-shaped structures 
suspended from the extremities of long thin branches of trees, leaning out over the small creeks in the 
scrubs, are often very handsome in their construction, frequently being beautifully decorated with skeins
