THE BIRDS OF AUSTRALIA. 
last revision upholds all the above as fairly well-defined sub specific forms 
though intergradation is not infrequent. However I am compelled to add 
another and have also included the New Guinea forms, as Robinson and 
Laverock concluded. I am quite unable to appreciate the crest differences 
defined by Rothschild and Hartert. 
North’s remarks on the variation read : “ With a species having so wide 
a distribution, it is natural that one finds a great difference in size when a large 
series of skins are brought together and examined. The variation in plumage 
is small, and is chiefly in the ear-coverts ; in many they are white, or show but 
a slight tinge of their pale sulphur-yellow bases ; in a few only they are pale 
sulphur-yellow. . . . The wing-measurement varies in adult specimens obtained 
even in the same locality. Typically the birds from South-eastern Australia 
are larger than those from Northern and North-western Australia.” 
I would then recognise as subspecies the following forms : 
Kakatoe galerita galerita (Latham). New South Wales. 
This is undoubtedly a large form, but may not be the largest. I have 
measured males from 342 to 350 mm. in the wing ; females measure in the 
wing from 330 to 355 mm. while some unsex ed specimens go up to 375 mm. 
The average of a dozen birds gives the wing as 344 mm. This form probably 
ranges into North Victoria as I measure a bird from that locality as 357 mm. 
in the wing. It also occurs north into South Queensland. 
Kakatoe galerita inter jecta subsp. nov. Victoria (South?). 
I introduce this name for the Victorian birds as these are certainly less 
in their measurements as regards the wing while the bill is certainly larger and 
approximates to that of the next subspecies. If my name be not approved of 
these can be referred to as Kakatoe galerita galerita-licmetorhyncha which reads 
rather harshly. I have noted that the North Victorian birds may be referred 
to the typical subspecies, in which case the present subspecies averages under 
330 mm. in the wing. 
Kakatoe galerita licmetorhyncha (Bonaparte). Tasmania. 
This form separated sixty years ago on account of the projecting and long 
bill which recalled that of the genus Licmetis is still scarce in collections. No 
long series is available, but the bill characters seem constant and in size it 
equals the typical form, Gould even considering it to exceed that. 
Kakatoe galerita rosince (Mathews). South Australia. 
The Kangaroo Island bird was named by me on account of its small size, 
and apparently this feature impressed itself upon those who observed it in 
nature as recorded in the preceding pages. As a matter of fact, the specimens 
so far handled, few in number it is true, are the smallest I have met with from 
184
