THE BIRDS OF AUSTRALIA. 
Ca lyptorhynchus banksii naso Gould. 
South-west Australia. 
Type-locality, Swan River. 
Even as North concluded, I have been unable to appreciate any 
differences in the bill when comparisons are made with series of examples. 
There is, however, a good deal in size, the Western bird being much smaller, 
the adult birds before me varying in the wing from 377 to 389 mm., no 
difference in size being remarked between male and female. The average 
of typical birds is much larger, specimens varying from 434 to 451 mm. in 
the wing. Immature females appear to be much more barred underneath, 
and the yellow of the tail usually washed with red, instead of pure yellow 
as in the typical form. 
Calyptorhynchus banksii samueli subsp. nov. 
Central Australia. 
Type in my collection from Hugh River, Central Australia, collected 
by Capt. Samuel A. White, September 2nd, 1913. 
A series of specimens were at once remarked upon by the consistent small 
size of the bill, and they varied from 387-402 in the wing, being thus slightly 
larger than West Australian birds, though still small. I also noted that the 
bands on the under-surface of the females were duller in coloration than in the 
case of the Western bird. Since this conclusion was drawn, I have observed 
that North, in the Report of the Horn Scientific Expedition to Central Australia, 
recorded five specimens with full measurements and remarked : “ The males 
are similar in size and plumage to examples obtained at King George’s Sound ; 
in one specimen, the crimson band across the median portion of the tail- 
feathers extends in a narrow line along the shaft of the outer web of the 
outermost feather on either side. The cross-bars on the under-surface and 
under tail-coverts of the females are less numerous and much duller in colour 
than in specimens procured in West Australia.” North used for this form 
the specific name stellatus then in use for the West Australian bird, and 
recently Capt. S. A. White also used the same name for the Central form. 
I consider the Central form a well-marked subspecies, and have therefore 
provided the above name for it, named in honour of my great friend Samuel 
Albert White of Wetunga, Fulham, South Australia. Until North charac- 
terised it, no scientist had examined specimens, though Sturt recorded 
Calyptorhynchus funereus ? — a species not met with by recent Central Australian 
explorers. The status of the name stellatus I herewith discuss. 
Calyptorhynchus stellatus as of Wagler has been used in place of C. naso 
Gould, but I conclude without valid reason. I have noted that monographers
