1921 .] Western Australian Birds. 63 
Sphenura brachyptera longirostris. 
No signs of Long-billed Bristle-birds were seen or heard 
in any of the coastal scrubs that were visited in the south¬ 
west area, although I spent several days at the place where 
the last known birds were seen some years ago ; but the 
localities where these birds may still be living extend along 
such a great stretch of the coast, and are so densely clothed 
in scrub, that it is very easy to miss seeing such a very shy 
and seclusive species. 
Artamus leucorhynchus leucopygialis. 
The first time White-rumped Wood-Swallows were ever 
seen by me was at Carnarvon on 24 September, 1911, when 
a small party was flying about Babbage Island, but were 
very wild. Many of these birds were seen^at exactly the 
same place and same day of month in 1913, and some 
specimens obtained. No examples were seen in 1916. 
Campbellornis personatus. 
Masked Wood-Swallows were numerous about Broome 
Hill in early January 1916. These birds are very erratic 
in their visits. 
Austrartamus cinereus tregellasi. 
Black-vented Wood-Swallows were seen in the Gascoyne 
and Minilya districts on all three trips, but were most 
plentiful in 1916, when many nests containing eggs or 
young were seen in September. A nest with three eggs 
was seen at the Minilya on 9 September, 1911. 
Angroyan cyanopterus. 
Wood-Swallows were common in the south-west districts. 
Micrartamus minor derbyi. 
Little Wood-Swallows were only seen in Shark Bay, and 
in some of the deep gorges in the North-West Cape ranges, 
where they breed in holes of the cliffs. When at the Yardie 
Creek on 26 August, 1913, I saw the parent birds feeding 
their young in a nest that was out of sight in a crevice of 
the roof of a large cave.
