Medium-sized Anseriform birds with short biU, short maned neck, long wings, 
medium tail, short legs and feet. 
The bin is short and of medium depth for this group, of about the same 
length as the head ; the nostrils are comparatively large ovals placed mid-way 
down the culmen, the culmen ridge not weU differentiated ; the nail is not 
distinctly marked off, spatulate not pointed. 
The serrations on the inner edge of the upper mandible are few in number, 
placed rather distantly. The under mandible is flat, broadish, with flattened 
broad nail ; the rami are not prominent, enclosing a triangular space which is 
half feathered. 
The neck is short and there is a patch of elongated feathers on the 
hind neck. 
The wings are long, the first primary shorter than the second, which is 
longest, but longer than the third. 
The tail is much less than half the length of the wing, and rounded. The 
metatarsus is reticulate throughout, equal to half the length of the tail\and 
slightly longer than the middle toe. The toes are fully webbed, the hind 
toe short, narrowly lobed. 
The extraordinary nature of this form may be gauged by the fact that as 
the vernacular names chosen for its recognition two appear, viz., Wood-Duck 
or Maned Goose. No other Australian bird boasts of such an anomalous 
nomenclature. 
Gould wrote, p. 356 : “ Although I have applied the trivial name of goose 
to this bird, it has but little relationship to the typical member of the genus 
Anser, none of which, as stated in the introduction, exist in Australia, nor, so 
far as I am aware, in any of the Polynesian Islands.”
