Electron microscope studies of the mature nacreous layers fromBrachidontes recurvus(Rafinesque) andElliptio complanatus(Dillwyn) confirm the existence of tabular aragonite polygons interleaved with a perforate organic matrix. No evidence was found to support the concept of original component blocks orintracrystalline organic matriess. Replica studies of the immature, developing nacre reveal hollow “crystals”, thin “crusts”, subunits, and an abrupt transition to the mature shell material. A tentative explanation of some of the important features of the nacreous shell structure is offered.
