This species, which is much inferior in 7 size to the last, 

 and easily distinguishable from it by having the head entirely 

 black, arrives in October and departs in April. It is more 

 numerous than the other species, especially along the eastern 

 coasts, where it feeds chiefly on the cylindrical fleshy roots 

 of Zostera marina. It breeds in the arctic regions of both 

 continents, laying six or eight eggs, of a nearly elliptical 

 form, pale greyish-green, two inches and a half in length, an 

 inch and seven-twelfths in breadth.
