shinjnuf black-green; on each side of the neck a large dead- 

 green patch, surrounded by the black- green of the head. 

 Length, 14"; wing, 6"; tail, 2" "". 



This lovely little Goose may at once be knowa by its brilliant colour- 

 ing, particularly tbe green patch on each side of the neck. It is 

 abundant at Natal, where a friend informs me it swims in such large 

 flocks, tliat he has killed from ten to fourteen in a single discharge of 

 a common fowling-piece. Mr. Chapman found it equally abundant in 

 his travels to the northward ; but as yet I have not heard of its 'being 

 procured in the colony.

have the bill lengthened, more or less broad, depressed 

 towards the tip, which is furnished with a hard nail, and the 

 inner portion of the lateral margins more or less lamellated ; 

 the tarsi compressed, and generally the length of the inner 

 toe ; the hind toe lengthened, and slightly bordered with a 

 membranous lobe from the base to the tip.
