- W4247375897 abstract "A description of the frustular morphology of Amphipleura pellucida, based on electron micrographs of both entire frustules and sectioned material, is presented. The wall of the valve proper is of uniform thickness except for the thickened central nodule and the ribs surrounding the raphe. The regularly arranged punctae are about60mμ in diameter. Their internal opening is covered by a thin, porous plate with pores about 6-8mμ in diameter. Each intercalary band contains an elongate chamber which opens to the interior of the cell by a series of oval foramina and to the exterior by a slit between the valve mantle and intercalary band. The lower margin of the intercalary band contains a series of elongate foramina. Both types of foramina are covered, on the internal margins, by porous plates similar to those which cover the internal openings of the punctae." @default.
