Show 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 present 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 Zoological Society of Amsterdam. Of this bird we have now three examples alive in the Parrot-house, which have been hitherto wrongly named Cacatua ducorpsi\. 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. goffini, which was not previously known "f. I have no means of pointing out the precise differences between C. goffini and C. ducorpsi oi the Solomon Islands, no specimen of the latter being accessible. But it would seem that in C. ducorpsi the Fig. 1. Fig. 2. Foot of Cacatua goffini. Foot of Cacatua sanguinea. interior of the crest is lemon-yellow, not rosy red as in C. goffini^, * Plictolophus goffini, Finsch, Papag. i. p. 308. t The first is labelled as having been " purchased in 1864;" but this is probably an error; tbe second was presented by M r . C. Turner in June 1871, and the third presented by M r. S. F. Deane in October last year. | Mr. Cockerell tells m e 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. S. § I think it possible that the specimen which I spoke of (P. Z. S. 1871, p. 49U) 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 occasionally misplaced, and confusion thus arises. |
