Seven examples of this distinct species were obtained. It is very much 
larger than L. plumifera^ of the north-western coast, and from which it may be 
readily distinguished by the centre of the lower breast being white, and by having 
the feathers on the chest broadly tipped witli white, and forming a distinct band 
immediately above the grey and black ones. The range of this species extends 
throughout the whole of Central Australia, the Gulf District, and the interior of 
northern and north-western Australia. In the recently issued Catalogue of the 
CoLUMBiE in the British Museum, Count Salvadori has taken his description of 
L. plnmifera from .specimens of the Plumed Bronze-wing obtained by the late 
T. II. Bowyer-Bower at Derby, north-western Australia, and although varying in 
the description, judging by the measurements I have no doubt they are similar to 
the birds from which Could originally took his description of this species; but it 
must be remembered that in the Proceedings of the Zoological Society Gould 
described L. phiinifera as having two semi-lunar marks of white on the chest, 
which, meeting, form a point in the centre, and also figured it with this white 
band on the chest in his folio edition of the Birds of Australia. The Derby 
specimens have no white marks on the chest, but, as Count Salvadori points out, 
a crescentic band of grey, margined below with a narrower one of black. In the 
Proceedings of the Linnean Society of New South Wale.s, Dr. Ramsay referred 
the birds obtained by the late T. H. Bowyer-Bower at Derby to L. ferri/ginea, 
I’elying upon Gould’s statement in the Supplement to the Birds of Australia 
tlui.t Z. fen-ugitiea differs from Z. plnmifera and Z. leucogaster^ “in the 
absence of the broad white pectoral baud so conspicuous in those birds.” In 
conclusion, I would remark that I have examined a large series of the Plumed 
Bronze-wings from different parts of Australia, but I have never met with any
