reddish-bay, and edged with chestnut : 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 depending 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 570.
