Adult. Smaller than the preceding species but otherwise very 

 similar, except as regards the pattern of the outer primaries. These 

 have angular-edged mirrors on 1st and 2nd quills, while on 3rd 

 there is no mirror, but the basal half is white {see cut, p. 239) : 

 " iris silvery white" {Buller) ; bill, eyelids, tarsi, and toes crimson. 

 Total length about 14-5 inches, culmen 1-7, wing 11, tail 5, tarsus 

 1-75, middle toe with claw 1-75. 



The male is a trifle larger and more robust than the female. 



Young and Immature. As in the former species, except that 

 two small elongated white patches or incipient mirrors make their 

 appearance in the two outer pairs of primaries (see cut, p. 239), 

 while the bird has still a spotted back and a banded tail. 



Hah. New Zealand, Chatham and Auckland Islands. Examples 

 from the last have unusually short stout bills.
