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.
