discusses the possibility of there being two species, and in conclusion asks : "Are there 

 two different species of Psittirostra on the Sandwich Islands, or are the differences 

 pointed out above perhaps only due to age % " Since the publication of this paper 

 Dr. Stejneger has been kind enough to send me one of the specimens described in it — 

 an adult male — for comparison. I have carefully compared it with others from Hawaii 

 and cannot detect any marked difference, though it has the head rather brighter than 

 the average from that island ; while I imagine that the discrepancy which the author found 

 between it and Latham's description may have been due to the latter having had only 

 poor examples before him. I did not, however, obtain specimens from Oahu, and Herr 

 von Pelzeln may be right when he remarks (Ibis, 1873, p. 22), with regard to two 

 examples procured on Oahu as compared with Latham's type, " even the older one 

 [ s ] differs from Latham's male bird [then before him], the middle of the breast and 

 belly and the thighs being whitish ; " the latter in all probability came from Hawaii. 

 I may here remark that an immature male from Lanai has the under surface clear 

 primrose-yellow, with bright olive-green flanks, while the olive-green of the upper 

 parts is also brighter than in any other specimen which I possess. These variations are, 

 I imagine, due to age, as a female from the same island does not differ from one 

 from Hawaii. Examples from Molokai do not present any definite points of difference, 

 though perhaps they are somewhat duller beneath. I did not, as already remarked, 

 obtain a single bird from Maui 1 . 



1 Dr. Finsch (Ibis, 1880, p. 80) says " when collecting at Olinda, Maui, Psittirostra psittacea I saw repeatedly ; 

 but I lost those I shot, from their falling into the ferns." My friend Mr. Randal von Tempsky informs me 

 that he saw several specimens of this bird during a visit made to the Ukumehame Gulch in 1890.
