BIRDS—ALCIDAE—BRACHYRAMPHUS MARMORATUS. 
915 
This is the most frequent species of this group on the coast of the Middle-and Northern 
States on the Atlantic, and occurs nearly every winter as far south as the coast of New Jersey. 
It differs from either of the preceding in having the hill much shorter and wider, and is not 
difficult to recognize by its short and rather wide bill, though of the same colors of plumage as 
the preceding.
