No discernible distinction between the sexes, except that in the male {Jide ^Sleyer) the wing 

 exceeds by about half an inch that of the female. 



Dr. B. Meyer has kindly obliged me with the following remarks : — " The Philippine Cacatua 

 is wild on all the different islands I visited. All my specimens were shot in the forest. It 

 abounds on Luzon, Guimaras, Negros, in the forests ; there I saw it myself; but I do not doubt 

 it will be the same on the other islands."

Hah. Luzon, Guimaras {Meyer) ; Mindanao (Cmning). 



An example from Guimaras ( ? fde Meyer) has the top and back of the head turning to 

 blue, as in the male, and closely resembles a male from Luzon. 



A Luzon individual ( 6 fide Meyer) has the entire body-plumage bright yellow-green 



without any traces of blue or verditer about the head. All the lateral rectrices have a broad 



Tr. Z. S. is. deep-blue terminal band, much fresher and more intense in colour than in the adult male. 



'^' ' ' Wing slightly shorter ; but naked shafts of middle rectrices quite as long as in the adult male. 



■ Seemingly first plumage. 



Another from Luzon ( s fide Meyer), in the same uniform light-green plumage, but with 

 the blue of the terminal caudal band less intense, the wing much shorter, and the shafts of 

 middle rectrices naked only on one side, the naked part not exceeding a quarter of an inch. A 

 still younger bird. 



In an old Guimaras male the naked shafts measure an inch only, instead of two and a half 

 or three inches. 



If all these examples are correctly sexed, the adult male and female plumages do not differ. 



I agree with Dr. O. Finsch {torn. cit. p. 404) in uniting P. discurus and P. sjpatuliger. 



t Dr. 0. Pinsch {I. c.) gives 1834. 1825 is the date on the titlepage of the &-st volume ; but as the work aispearcd in 

 parts, the date of the second part is probably earlier than even lb2o. The plate is quoted in the Tableau Encyclopedique, 

 vol. iii. p. 1369, published in IS'2'3.
