Forms: 1800s Molluscoida, 1800s Molluscoides, 1800s– Molluscoidea.

Etymology: < scientific Latin Molluscoida, Molluscoidea < French Molluscoïdes , plural (H. Milne-Edwards Élémens de zool. (ed. 2, 1843) III. 238) < Mollusca Mollusca n. + French -oïdes , plural of -oïde -oid suffix.The available data gives no evidence of grammatical agreement, though names in -oidea generally take plural agreement.

Zoology. Now historical.

A former division of invertebrates comprising the groups Bryozoa (formerly Polyzoa) and Brachiopoda, now phyla in their own right, and originally also the group Tunicata (now the subphylum Urochordata of the phylum Chordata).

Molluscoidea1855

1855 Eng. Cycl., Nat. Hist. III. 858 Milne-Edwards has proposed a division of the Mollusca into the Mollusca proper, and the Molluscoida (Molluscoides), including under the latter class those Polype-like forms, the Polyzoa and the Ascidioida.

1869 T. H. Huxley Introd. Classif. Animals iv. 82 The Ascidioida, Brachiopoda and Polyzoa..may be conveniently denominated Molluscoida.

1870 G. Rolleston Forms Animal Life p. lxxxvii The Sub-kingdom Mollusca contains two great divisions or provinces—the Mollusca proper..; and the Molluscoidea, under which are comprehended the Brachiopoda, the Tunicata, and the Polyzoa.

1870 H. A. Nicholson Man. Zool. I. xlv. 249 (heading) Distribution of Molluscoida in Time.

1906 Pliocene & Pleistocene (Maryland Geol. Surv.) 210 Molluscoidea. Class Bryozoa. Order Chilostomata. family Membraniporidæ. Genus Membranipora Blainville.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) II. 314/1 They [sc. Brachiopoda] have been included with the Bryozoa in the phylum Molluscoidea but are now recognized as a distinct phylum.

1969 Systematic Zool. 18 250 The term Molluscoidea, used for some time to denote ‘Bryozoa plus Brachiopoda’, was not redefined when the two subordinate groups were raised to phylum rank.
