THE BIRDS OF COObABAH AND BREWARRINA— NORTH. 137 



On the 6tli October, 1915, being tlie first morning I was 

 shooting at Coolabah, one of tliese birds was procured close to 

 the ground, among the leafy branches of a low spreading Wilga. 

 On picking the bird up, for I was too far away to see what it 

 was when firing, found it was AcaiitJiiza albiveutris, described 

 by me in "Nests and Eggs of Birds found breeding in Australia 

 and Tasmania" in 190-1. Unfortunately, although the body 

 feathers were perfect, most of the quills of both wings were 

 more or less damaged by the dust shot, and expecting to get 

 more birds of this species, did not keep it. This was the only 

 example seen, although subsequently others were diligently 

 seai'ched for. I first obtained this species in a low brigalow 

 scrub of West Narrabri, in November, 1896. I have never 

 seen a specimen of the true Acdnthiza pyi'^'hopi/gia, of Gould 

 procured in New South Wales, the type of which was obtained 

 by Grould in the Belts of the Murray, South Australia, and for 

 which the present species was previously mistaken, but doubt- 

 less it may occur in the extreme south-western portion of the 

 State.

This well-known species was more frequently met with at 

 Coolabah than at Brewarrina. Known locallv in many parts 

 of New South Wales under the name of " Yellow-tail " from 

 its bright yellow upper tail-coverts — which show conspicuously 

 during flight — also "Tomtit "and "Double-dick," the latter 

 from its habit of constructing a double nest; the lower one be- 

 ing dome-shape and the one built on top of it cup- 

 shape. Generally it is formed in the thick leaf}' end of a low 

 drooping branch.
