THE BIRDS OF AUSTRALIA. 
Hartert himself, and there was no doubt whatever of the perfect validity of 
his name, and it was only through an error that Hartert renamed Gould’s 
form. 
In my “ Reference List ” I accepted two forms, an eastern and western 
one, as 
Artamus leucorhynchus leucopygialis Gould. 
Queensland, New South Wales. 
Artamus leucorhynchus harterti Mathews. 
“ Differs from A. 1. leucopygialis in being much paler above (Parry’s 
Creek), North-west Australia.” 
North-west Australia, Northern Territory. 
I later named 
Artamus leucorhynchus melvillensis. 
“ Differs from A. 1. leucopygialis in its small wing and darker upper- 
surface.” 
Melville Island, Northern Territory. 
but in my 1913 “ List ” I synonymised this with the preceding, allowing 
only the two I admitted in the “Reference List.” This is probably incorrect, 
as although these birds are to some extent migratory, they appear to show 
good geographical variation, but long series are very necessary. Therefore 
I still allow the above, but to the range of A. 1. leucopygialis must be added 
Northern Victoria and South Australia.
