   (l[i^][ng]*gw[a^]t`[-u]*l[imac]"n[.a]), n. pl. [NL., fr. L.
   lingua tongue.] (Zool.)

   Note: The adults of some species inhabit the nostrils and
         nasal sinuses of dogs and other carnivores. The young,
         after being swallowed by sheep, rabbits, etc., find
         their way to the lungs and liver and become encysted.
         These, when eaten by carnivores, develop into the adult
         forms.
         [1913 Webster]
