continent; breeds, like its congeners, on the coast in northern latitudes, making its nest near the 

 water mark of grass, sea weed, and other rubbish, and near the time of hatching lines its nest with

The trachea is very dissimilar from that of the two following species, having no bulb below 

 the glottis, and the tube only enlarged to about twice its usual diameter in place of the inferior 

 bulb ; the inferior larynx is similar to that of its congeners. The trachea of the female is similar 

 to that of the male, but not quite so much enlarged; both sexes have the bronchia? large, and the 

 tube acted upon by two pair of muscles, situated as in the velvet scoter.
