Trachea Linn. Trans, col. 15, tab. \5,fig. h. 



Inhabits the neighbourhood of the arctic circle, breeding in Iceland, Siberia, Kamschatka, and 

 the fur countries, making its nest of grass near the water, and laying from ten to fourteen eggs of a 

 yellowish colour. During winter, in hard weather, these birds migrate southwards, and are found 

 over considerable portions of the continents of Europe, Asia, and America. We have also received 

 them from Peru. 



The trachea in the male has two enlargements on the tube, each of which are compressed, and 

 composed of alternating semi-lunar plates. 



The inferior larynx is very large and strong, projects most on the left side, but slightly before. 

 behind, and on the right side. The bronchia? are far apart, the left the largest ; it does not differ 

 in form from that of M. serrator, which we have figured.
