the crown and upper parts. The wing in six specimens 

 measures l - 85-l"9 inch ; tarsus 075. 



In the adult female the crown is olive-green like the rest 

 of the upper parts, only the feathers at the base of the bill 

 inclining to olive-brown. The wing measures 1°9 inch,' 

 tarsus - 73. 



Young birds have the upper parts olive-green like the 

 adult, only the feathers of the crown and nape being pale 

 brown with marginal streaks of blackish, and the chin, throat, 

 and breast more faintly spotted with brown than in the 

 young of A. citrina, 



I have examined four specimens in this stage of plumage, 

 two being young males preserved in spirits, sent with their 

 male parent from Marlborough.

 This species has been generally confounded with the closely 

 allied form A. chloris, Sparrm., but the adult male may be at 

 once recognized by the wide and strongly defined white eye- 

 brow stripe and by having the mantle and back of a bright 

 sap-green colour, the rump and upper tail-coverts yellow, 

 faintly tinged with greenish, but contrasting strongly with 

 the back, and the sides, flanks, and under tail-coverts bright
