ANATID.E, 



wing-coverts white ; the smaller coverts tipped with black ; 

 the wing-primaries almost black, tinged Avith green ; the 

 secondaries tinged with reddish-bay, and edged with chest- 

 nut ; the lower part of the back, the rump and tail, nearly 

 black ; front of the neck, the breast, and upper part of the 

 belly, pale rufous brown, a patch on the breast chestnut 

 brown ; lower part of the belly and the vent pale brown ; the 

 legs and feet pink. 



The whole length of an adult male about twenty-six inches. 

 The distribution of colours are the same in females as in 

 males, but the tints are less bright and pure. The wing is 

 furnished with a short blunt spur at the wrist. 



The tube of the windpipe is about twelve inches long, 

 nearly cylindrical in form throughout ; but unlike those of the 

 other geese, the male has a hollow bony enlargement, half 

 as thick as it is wide ; at the bottom of the tube on the left 

 side, as shown in the vignette below, where the lower portion 

 of the windpipe, the bony enlargement, and the short de- 

 pending bronchial tubes, the last slightly connected by a thin 

 slip of membrane, are figured of the natural size. The view 

 is taken with the tube and its enlargement in the natural 

 position, the breast-bone being removed, as in the case of the 

 view of the windpipe of the Spoonbill figured in the second 

 volume, page 504.
