THE BIRDS OF AUSTRALIA. 
Same as McArthur River birds, which do not differ from North-west 
specimens {parry i Mathews). North Queensland specimens have more grey 
on the breast, for which Mathews has suggested the name stallceri .” 
Still later, writing of birds from Torres Straits Islands, Campbell observed : 
This species is found in New Guinea, also the Solomons (examples from 
both localities are in the National Museum, Melbourne). It does not appear 
to vary from North Australian birds. Specimens from all localities appear 
to have more or less a greyish tone on the breast. Seen a few times.” 
This would agree with Hartert’s conclusion, as he considered the Northern 
Australian birds to be simply subspecies of the New Guinea species G. papuensis, 
and the Solomons form was named G. elegans by Ramsay. 
The differences observed in the specimens seem to be of specific value 
in this group, and therefore I retain the name hypoleucus as the species name 
of the Australian birds. 
In 1912 I distinguished : 
Coracina hypoleuca stallceri 
from Cooktown, Queensland, stating that it differed in its slightly smaller 
bill and in having a distinct greyish band on the breast. Culmen 19 mm., 
wing 153 mm. ; typical culmen 23 mm., wing 145 mm.” 
From Melville Island I named : 
Coracina hypoleuca apsleyi 
as differing from C. h. hypoleuca “ in its smaller size and in having a light grey 
jugulum, and French grey feathers on the tibia.” 
From Parry’s Creek, North-west Australia : 
Coracina hypoleuca parryi , 
on account of its fighter upper coloration. 
In my “ List of the Birds of Australia ” in 1913 I regarded the Melville 
Island form as doubtfully synonymous of the typical race described from 
Port Essington. 
On account of the acceptance of Graucalus as the genus name, the forms 
may be recorded as : 
Graucalus hypoleucus hypoleucus Gould. 
Northern Territory. 
Graucalus hypoleucus apsleyi (Mathews) ? 
Melville Island, Northern Territory. 
Graucalus hypoleucus parryi (Mathews). 
North-west Australia. 
Graucalus hypoleucus stallceri (Mathews). 
North Queensland.
