  • Disencumbered of the brachiopods, the Conchifera correspond to the Acephala testacea of Cuvier, or to the Lamellibranchiata of De Blainville and modern naturalists. Also called Conchophora, Acephala, Endocephala, Lipoccphala, and Pelecypoda.
  • In Gegenbaur's system of classification, one of two primary divisions of the Mollusca; the Mollusca of authors in general, exclusive of the Placophora or chitons.
