Dr. van Oort {Nooa Guinea i.v., Zool. livr. i. p. 70) calls this bird Cacatua 



galerita tritoti, which is probably more correct, but we cannot at this moment review 



this group of Cockatoos.

 This bird was described as a subsjiecies of N. -pygnaea., and nufortunately the 

 close relationship to N. keiensis was overlooked, owing to its close resemblance 

 to the females of N. pygmaea. However, it is not absolutely identical with 

 iV. keiensis /leiensis, as Mr. Ogilvie-Graut makes it out (in A. F. R. Wollastou's 

 Pijqmies and Papuas, p. 287), but it differs from the latter by its smaller bill and 

 slii^'htly shorter wings. Wings of three males 62, and of a ? considerably under 

 60 mm., as opposed to 63 — 65 in the males and 61 to 62 in females of N. keiensis 

 keiensis.
