5" In Odlober. 1S99, I saw. a specimen in the buslies up Moanalna valley which I believe to liave been the above species, though of course 

 I cannot be positive of the identity. ' Since the preparation of the above, Mr. Rothschild (Birds of Laysan, Part III., page 19.^) has separated 

 the Oahu form from the. Hawaii liird, giving the principal differential charatfler as "having the middle of the breast and belly, the feathers 

 of the tibia and under tail coverts whitish ; whereas, the adult males of the Hawaii bird "have the under parts olive green merging into whit- 

 ish only in the middle of the lower abdomen." The name given to "the Honolulu Ou" is Psittacirostra olivacea. Roths. 



5' With a good series of birds before me I am unable to separate ca/r/cim. Wilson, iro^uj/az'iss/tna, Roths. The latter seems to be onl\- 

 fully mature specimens of the former, atid in a plumage which requires some time for the iudividual to assume. Director Wm, T. Brigham 

 also informs me that specimens brought from Laysan and kept in*his aviary for a long time passed through several of the intermediate stages 

 on the way from mutant to Jfa7'isit//ni before they were accidentally killed.
