Adult. Like C. galerita, from which it differs in having the naked 

 skin round the eyes blue, and also in the dimensions, which are 

 generally smaller. Total length IS inches, wing 13, bill 1*70, 

 tarsus 1-10. 



Female. Smaller than the male. 



Hub. The Papuan Islands — New Guinea, Mafor, Mysori, Jobi, 

 Miosnom, Waigiou, Salwatty, Guebeh, Mysol, Aru Islands, Trobriand 

 and Normanby Islands, Louisiade Isl. ; and the Moluccan Islands, 

 Coram and Monawolka, where it has been imj)orted. 



The specimens from the Western Papuan Islands (Waigiou, 

 Salwatty, and Mysol), and especially from the Aru Islands, are 

 geuerally smaller than those from the mainland, and have even been 

 separated specifically as C. macrolopha, Rosenb. ; but I do not think 

 that we are justified in accepting this view, especially when we con- 

 sider the great range of individual variation. Also the birds from 

 the Trobriand Islands have been separated by Dr. Pinsch as Cacatua 

 trobriandi, but he writes to me that now he considers this name only 

 a synonym of C. triton. 



The specimen procured during the voyage of the ' Alert,' men- 

 tioned below, seems to belong to C. triton, but I suspect that it has 

 been importod into Hammond Island.
