WHITE COCKATOO. 
Hartert took up Finsch’s name trobriandi and fixed this, but there is a 
Cacatua galericulata Rosenberg (Reis naar de Zuidoostereil, 1867, p. 100), 
which is a nomen nudum and is corrected on p. 125 to Cacatua triton. 
It is mentioned as occurring on Goram. 
The subspecies and names I have determined as : 
Kakatoe galerita macrolophus (Rosenberg). Mysol, Salwatty, Waigou. 
Should the Waigou birds prove separable they might bear the name 
K. g. eleonora Finsch, which otherwise may be cited as a synonym. 
Kakatoe galerita subsp. indet. Arfak Peninsula. 
It is improbable that this is identical with the Dutch New Guinea form, 
but series are not available. They appear from Van Oort’s data to be a little 
larger than triton and much larger than macrolo'phus. 
Kakatoe galerita triton (Temminck). Dutch New Guinea. 
As synonyms may be noted Cacatua cyanopis Blyth, and perhaps C. 
galericulata Rosenberg. It will be noted from the notes already given that 
Van Oort’s measurements differ from those of Rothschild and Hartert, but 
these latter authors give different figures each time they write upon the subject. 
It is possible that immature birds may have something to do with the dis- 
crepancies seen. Thus they have written : “ The Fergusson Island bird 
has the wing measuring only 267 mm. (a few lines above given as 263) while 
Mysol specimens have the wing 280 mm. long and the wings of those from 
Dutch New Guinea measure 320-330 mm.” 
Later. “ The Sudest Island Cockatoo is exactly the same as the one from 
Fergusson. Another smaller subspecies, intermediate between C. triton 
triton and C. triton macrolopha (error for C. t. trobriandi) or equal to the latter 
is the form from the Western Papuan Islands. The Sudest Island birds 
measure, wings 268-292 mm.” Still later : “ It is most peculiar to\ find 
typical triton on the South-east Islands. Cacatua triton trobriandi. Although 
this form is somewhat larger than C. t. macrolopha .” At first they had 
found it smaller, then it was equal, now it is larger. It must be a very 
undecided subspecies. 
Kakatoe galerita aruensis subsp. nov. Aru Islands. 
It is obvious that this form needs nomination as it is smaller than 
macrolophus and geographically cannot be associated with it. Van Oort’s 
series show its validity and it demands recognition. 
Kakatoe galerita subsp. indet. South East New Guinea. 
A different race probably inhabits this country. The Port Moresby 
specimen recorded by Robinson and Laverock does not agree with Dutch 
New Guinea birds in measurements, but no series are at hand.
