Interstitial marine rhizopods (Protozoa) from littoral sands on the East Coast of England

The detailed structure and morphology of the shells of foraminifera and marine testate amoebae found interstitially in littoral sands have been studied by light- and scanning electron microscopy. Species are described within the known taxa. A comparison of shell architecture shows similarities in construction between those shells made from defined plates with those made from agglutinate particles, but lack of biological information prevents suggestions on possible phylogenetic connections. The testacean genus Lagenidiopsis Golemansky, 1974 is transferred to the foraminifera. Empty Tintinnid loricae may possibly be confused with empty testate shells.
