W h e n dried skins only are examined it is not easy to distinguish this Cockatoo from its Australian'
representative Cacatua galerita; but when living individuals of the two species are compared together, the
colour o f the naked blue skin th at surrounds the eye renders the present bird a t once remarkable. It
is besides slightly smaller in size than Cacatua galerita, and has usually rath er a stronger bill. In other
respects the Triton Cockatoo exactly resembles the well-known Sulphur-breasted Cockatoo o f the Australian
continent.
Although confounded with C. galerita by some o f the older authors, the Triton Cockatoo was recognized
as distinct by Temminck in 1849, and named after one o f the Dutch surveying-vessels which first visited
the coasts of New Guinea. I t appears to be found all over that large island, and to be, in some places, very
abundant. T h e numerous flocks o f white Cockatoos which Dr. Solomon Muller observed on the southwestern
coasts o f New Guinea, near Triton Bay, were doubtless o f this species, although that celebrated
explorer did not distinguish them from C. galerita. There are fine series o f specimens o f this Cockatoo
from the islands o f Waigiou and Guebe in the Leyden Museum, and in the same collection is now also the
type of Cacatua eleonora o f D r. Finsch, originally described from the living bird in the Zoological Gardens of
Amsterdam. It likewise occurs in the islands o f Geelviuk Bay, Salwati, Mysol, the Aru Islands, Gorarn, and
Manuwolka, and is met with in the Louisiade Islands.
O u r figure o f this species is taken from a fine example now living in the Parrot-house o f the Zoological
Society o f London. This individual was brought home from New Guinea by M r. C. T . Kettlewell, F.Z.S., in
his yacht ‘ Marquesa,’ and presented to the Society in April 1884.
