5<^ In Oc5lober, 1899, I saw a specimen in the bushes up Moanalua valley which I believe to have been the above species, though of course 

 I cannot be positive of the identity. Since the preparation of the above, Mr. Rothschild (Birds of I^ysan, Part III;, page 193) has separated 

 the Oahu fonn from the Hawaii bird, giving the principal differential character as "having the middle of the breast and belly, the feathers 

 of the tibia and under tail coverts whitish ; whereas, the adult males qf 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, 



51 With a good series of birds before me I am unable to separate cantans, Wilson, from ^avzssima, Roths. The latter seems to be only 

 fully mature specimens of the former, and in a plumage which requires some time for the individual to assume. Diredlor Win. T. Brighani 

 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 cantans to Jlavissima before they were accidentally killed.
