THE BIRDS OF AUSTRALIA. 
“ Cacatoes sanguined a/psleyi subsp. n. 
Differs from C. s. distincta in its much larger bill and smaller wing. 
Range. Melville Island. 
Cacatoes sanguined ashbyi subsp. n. 
Differs from C. s. sanguined in its smaller bill and wing, and the bare 
eye-ring much smaller. 
Range. New South Wales.” 
I again reviewed the species for my “ List of the Birds of Australia ” and 
the erratic distribution of the forms appeared very perplexing. After much 
consideration I concluded that probably two species were confused, one with 
a round eye-space ( sanguined ) and one with an irregularly developed eye- 
space (gymnopis). This arrangement seemed preferable and I so listed the 
forms, thus : 
“ Ducorpsius sanguineus. 
D. s. sanguineus. 
D. s. ashbyi. 
Ducorpsius gymnopis . 
D. g. gtjmnopis 
D. g. subdistinctus. 
D. g. distinctus. 
D. g. apsleyi 
Northern Territory. 
New South Wales. 
Interior South Australia : West 
Australia. 
North-west Australia. 
Northern Territory (Inland). 
Melville Island.” 
It may be remarked that when Witmer Stone published “ A List of the 
Species of Australian Birds described by John Gould,” with the location of 
the Type-specimens, the type of Gould’s Cacatua sanguined was recorded as 
being in the collection of the Philadelphia Academy, giving a note ( Austral . 
Av. Bee., \ ol. L, p. 148, 1913) : “ A specimen in the British Museum is marked 
type ’ ( Cat. Birds , Vol. XX., p. 128), but the collection sent to Philadelphia 
was stated to contain all the types of species described by Gould from his own 
material, up to that tune. In several other cases Gould specimens in the 
British Museum are erroneously marked ‘ type.' ” 
The above determinations had been made in connection with the British 
Museum material and the type there marked had been accepted as such, while 
a bird received from the Zoological Society had been regarded as the type of 
Sclaters C. gymnopis. 
Correspondence with Australian workers had shown that North’s con- 
clusion was more acceptable to them and that only one species occurred in 
Australia. Mr. F. L. Berney expressed the opinion that a young bird might 
show in the skin a somewhat small circular eye space, but that no adult
