60 MR. P. L. SCLATER ON SOME RARE PARROTS. [Feb, 2, 
A recent examination of the living specimens of White Cockatoos now 
in the Society’s Gardens has convinced me that we have at the pre- 
sent moment examples of a fourth, nearly allied species, which I had 
not previously recognized. This is the Cacatua goffini described by 
Finsch* in 1863 from a specimen living in the Gardens of the Zoo- 
logical Society of Amsterdam. Of this bird we have now three ex- 
amples alive in the Parrot-house, which have been hitherto wrongly 
named Cacatua ducorpsit. I also exhibit a skin of the same species 
from the collection of Messrs. Salvin and Godman. This specimen 
is of great interest, as it was obtained by Mr. J. T. Cockerell at 
Coomara in Queensland, about 30 miles from Brisbane, and thus fixes 
the habitat of C. gofini, which was not previously known f. 
I have no means of pointing out the precise differences between C. 
gofini and C. ducorpst of the Solomon Islands, no specimen of the 
latter being accessible. But it would seem that in C. ducorpsi the

+ The first is /ahelled as haying been “ purchased in 1864;” but this is proba- 
bly an error; the second was presented by Mr. C. Turner in June 1871, and 
the third presented by Mr. 8. F. Deane in October last year. 
¢ Mr. Cockerell tells me he shot this bird in December 1873, out of a flock of 
the ordinary Cacatua galerita, and never met with a second specimen.—P. L. 8S. 
§ I think it possible that the specimen which I spoke of (P. Z. 8. 1871, p. 490) 
as C. ducorpsi may not have been realiy one of the original pair of this species, 
but an example of C. goffini. In spite of every care, labels on living birds are occa- 
sionally misplaced, and confusion thus arises.
