EGYPTIAN GOOSE. 308 



In a young bird hatched at Mr. Cecil Smith's, in March 

 1882, which flew away and was shot in August, the head was 

 more mottled, and the under parts and mantle more marked 

 with grey and brown vermiculations than in the adult ; the 

 secondary wing-coverts white with grey and black margins, 

 forming an ill-defined bar ; tail nearly black, mottled with 

 brown ; line at the base of the bill pink, and not black, as in 

 the adult ; feet dull pink. 



A nestling had the bill horn-black ; upper parts dark 

 brownish-grey; under parts dirty-white ; feet clay- coloured. 



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 present volume.
