  Sheathbill \Sheath"bill`\, n. (Zool.)
     Either one of two species of birds composing the genus
     {Chionis}, and family {Chionidae}, native of the islands of
     the Antarctic seas.
     [1913 Webster]
  


     Note: They are related to the gulls and the plovers, but more
           nearly to the latter. The base of the bill is covered
           with a saddle-shaped horny sheath, and the toes are
           only slightly webbed. The plumage of both species is
           white.
