When 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 of the naked blue skin that surrounds the eye renders the present bird at once remarkable. It 
is besides slightly smaller in size than Cacatua galerita, and has usually rather a stronger bill. In other 
respects the Triton Cockatoo exactly resembles the well-known Sulphur-breasted Cockatoo of the Australian 
continent. 
Although confounded with C. galerita by some of the older authors, the Triton Cockatoo was recognized 
as distinct by Temminck in 1849, and named after one of the Dutch surveying-vessels which first visited 
the coasts of New Guinea. It appears to be found all over that large island, and to be, in some places, very 
abundant. The numerous flocks of white Cockatoos wbicb Dr. Solomon Muller observed on the south- 
western coasts of New Guinea, near Triton Bay, were doubtless of this species, although that celebrated 
explorer did not distinguish them from C. galerita. There are fine series of specimens of this Cockatoo 
from the islands of M^aigiou and Guebe in the Leyden Museum, and in the same collection is now also the 
type of Cacatua eleonora of Dr. Finsch, originally described from the living bird in the Zoological Gardens of 
Amsterdam. It likewise occurs in the islands of Geelvink Bay, Salwati, Mysol, the Aru Islands, Goram, and 
Manuwolka, and is met with in the Louisiade Islands. 
Our figure of this species is taken from a fine example now living in the Parrot-house of the Zoological 
Society of London. This individual was brought home from New Guinea by Mr. C. T. Kettlewell, F.Z.S., in 
his yacht ‘ Marquesa,’ and presented to the Society in April 1884.
