Molluscoidea \Mol`lus*coi"de*a\, n. pl. [NL. See Mollusk, and
   -oid.] (Zool.)
   A division of Invertebrata which includes the classes
   Brachiopoda and Bryozoa; -- called also Anthoid Mollusca.
   [1913 Webster]

   Note: Originally the Tunicata were included under
         Molluscoidea, from which they are known to differ
         widely in structure and embryology. Molluscoidea were
         formerly considered a subdivision of Mollusca, but they
         are now known to have more relationship with Annelida
         than with Mollusca.
