EGYPTIAN GOOSE, 



303 



In a young bird batched at Mr. Cecil Smitb's, in Marcb 

 1882, wbicb flew away and was sbot in August, tbe bead was 

 more mottled, and tbe under parts and mantle more marked 

 witb grey and brown vermiculations tban in tbe adult ; tbe 

 secondary wing-coverts wbite witb grey and black margins, 

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

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

 tbe adult ; feet dull pink. 



A nestling bad tbe bill born-black ; upper parts dark 

 brownisb-grey ; under parts dirty-wbite ; feet clay- coloured. 



Tbe tube of tbe windpipe is about twelve incbes long, 

 nearly cylindrical in form throughout ; but, unlike those of 

 tbe 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, tbe bony enlargement, and the short 

 depending bronchial tubes, the last slightly connected by a 

 thin slip of membrane, are figured of tbe natural size. The 

 view is taken with tbe tube and its enlargement in tbe 

 natural position, tbe breast-bone being removed, as in the 

 case of tbe view of tbe windj^ipe of tbe Spoonbill figured in 

 tbe present volume.
