The fine structure of the mesogloea of the column of Pachycerianthus fimbriatus McMuRRICH, a ceriantharian anemone, has been investigated. The mesogloea is bounded by basal laminae. It contains two classes of fibrils. Bundles of fibrils arise opposite projections of the endodermal epithemuscular cells and cross the main mesogloeal layer. In the remainder of the mesogloea individual liomuscular cells and fibrils are embedded in electron lucent material.
