Adult male. General plumage dark cinereous or bluish grey, tinged more or less on the upper surface of the 
wmgs and tail and on the rump and abdomen with dull brown; a band of velvety black, half an inch broad, 
surrounds the base of the bill, fills the lores, and encircles the anterior portion of the eyes; immediately 
a ove this band and continued over the eyes light ashy grey, shading into the darker plumage ; quills and

Nestiiny (only partially fledged). Frontal band very inconspicuous except in front of the eyes ; wattles extremely 
small and of a pinky colour. The plumage as in the adult but duller, and the wing-feathers washed on their 
outer vanes with brown. 
Nate. Professor Hutton is of opinion that the female is « rather larger than the male ; ” but my observations lead 
me to an opposite conclusion. I must admit, however, that I have found the size somewhat variable in both 
sexes. The wattle is always appreciably smaller in the female. In a pair from Wainuiomata, that of the 
male measured 7o of an inch in diameter, and that of the female only -5, besides being less rounded 
m form. 
Varieties. Theie is a fine albino specimen in the Colonial Museum, obtained in the Rimutaka ranges and 
piesented by a settler, who had it alive for several months. The whole of the plumage is white, with 
a creamy tinge on the fore neck and underparts ; the shafts of the quills and tail-feathers conspicuously
