THE BIRDS OF AUSTRALIA. 
The above refers to the two forms I separated hi my “Reference List" 
thus: 
Dicrurus bractealus bracteatiis Gould. 
Queensland, New South Wales. 
Dicrums bracteatus baileyi Mathews. 
“ Differs from D. b. bracteatiis in its larger whig—161 mm. Alligator River 
Northern Territory.” 
Northern Territory. 
These were maintamed in my 1913 “ List ” vith the addition of JS^orth- 
west Australia to the range of the latter and reference to the genus 
Dicruropsis. 
I have now introduced the genus Notochibia for tliis species and the two 
subspecies will be 
Notochibia bracteata bracteata Gould. 
Notochibia bracteata baileyi Mathews. 
The fact that the species is to some extent migratory does not invahdate 
the distinction of subspecies, as though Barnard has seen the Cape York birds 
in migration from New Guhiea there is at present no gromids for supposm 
that the North-west Austrahan birds go near New Gumea.
