at the ends ; upper part of the back and wing coverts brownish ash- 

 colour, the last palest ; lower part of the back, rump, tail, and 

 middle of the belly, vent, under tail coverts, and quills, black ; but 

 the sides of the breast and belly under the wings are grey, crossed 

 with minute undulated lines; speculum of the wing green, bounded 

 on each side with white, but the white is broader beneath than above ; 

 the outer webs of the scapulars black ; but the most distinguishing 

 character is, that the feathers of the breast have silvery grey ends, 

 and on each side of the grey a blackish spot, giving that part an 

 undulated appearance, spotted with blackish ; the wings, when 

 closed, do not reach quite to the end of the tail ; legs brown. 



The female differs in having the vent white, instead of black, 

 and the green speculum smaller, and less conspicuous. 



Inhabits New South Wales, most frequent about Hawkesbury 

 River, and now and then seen to perch on trees. 



Some birds have a longer crest than in others ; the head and 

 neck, too, are fine rufous, not unlike the same parts in the Pochard ; 

 from the lower part of the breast to the middle of the belly ash- 

 colour, beautifully marked with curved lines of brown ; on the back 

 four or five irregular large patches of black ; legs black.
