from Marlborough and elsewhere, though some Marlborough 

 birds were ealled A. citr'ma. 



Buller in the ' Supplement,' however, used A. cJdoris for 

 the North and South Island birds, and then admitted 

 A. citrina for the Alpine Rifleman from the Alpine country 

 of Nelson and quoted Grant as confirmation ! We have not 

 sufficient authentic material to decide as to the value of this 

 Alpine race but are separating the North Island Rifleman, 

 as the specimens from that Island lack the yellow^ rump and 

 yellow on the under parts of the Dusky Sound bird, only a 

 bare tinge of that colour being seen.
