ATTICORA LEUCOSTERNON, Gould. 
White-breasted Swallow. 
Hirundo leucosternus, Gould in Proc. of Zool. Soc, Part VIII. p. 172. 
Bob-de-bo6~de of the Aborigines of the mountain districts of Western Australia. 
Black and White Swallow of the Colonists. 
For the present I have placed this new and elegant Swallow with the members of the genus Atticora ; the 
type of which is the Hirundo fasciata of authors, a bird inhabiting South America, from which country I have 
seen two species, while South Africa presents us with a third ; the present, therefore, may be considered 
as the representative of the genus in Australia, thus further evidencing that beautiful law of representation 
alluded to in the page on Cypsehis Auslratis respecting the Swift,- Swallow and Martin. 
I have never myself seen this bird ; the specimen from which my original description was taken was pre- 
sented to me in 1839 by Mr. Charles Coxen, who had killed it some years before, and who informed me 
that it was one of a pair that he observed flying over a small lake in the neighbourhood of the Lower 
Namoi ; its companion was not procured. 
The second example was killed at Swan River, where Mr. Gilhert in his notes from Western Australia 
says, " I only observed this bird in the interior, and as far as I can learn, it has not been seen to the west- 
ward of York : I am told it is merely a summer visitor. It is a very wandering species, never very 
numerous, and is generally seen in small flocks of from ten to twenty in number, flying about, sometimes in 
company with the other Swallows, for about ten minutes, and then flying right away ; I noticed this singular 
habit every time I had an opportunity of observing the species. It usually flies very high, a circumstance 
which renders it difficult to procure specimens. 
" Its flight more nearly resemhles that of the Swift than that of the Swallow ; its cry also, at times, very 
much resembles that of the former. 
" Its food principally consists of minute black flies. 
" This bird chooses for its nest the deserted hole of either the Dalgyte (Perameles lagotis) or the Boodee 
(a species of Bettongid), in the side of which it burrows for about seven or nine inches in a horizontal direc- 
tion, making no nest, but merely laying its eggs on the bare sand." 
Crown of the head light brown, surrounded by a ring of white ; lores black ; a broad band commencing 
at the eye, and passing round the back of the neck, brown ; centre of the back, throat, chest and under sur- 
face of the shoulder white ; wings and tail brownish black ; rump, upper tail-coverts, abdomen and under 
tail-coverts black ; irides dark reddish brown ; bill blackish brown ; legs and feet greenish grey. 
The figures are of the natural size.
