\Lin*guat`u*li"na\
(l[i^][ng]*gw[a^]t`[-u]*l[imac]"n[.a]), n. pl. [NL., fr. L.
lingua tongue.] (Zo["o]l.)
An order of wormlike, degraded, parasitic arachnids. They
have two pairs of retractile hooks, near the mouth. Called
also {Pentastomida}.
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.
