title: [Hopper-crystal-growth, basis of test morphogenesis in Patellina corrugata Williamson (Foraminifera, Protozoa) (author's transl)].
abstract: During the growth of Patellina corrugata's test platelike structures are formed showing typical characters of Hopper-crystals. These features indicate conditions of test development comparable to inorganic skeletal crystal growth. The whole test therefore can be regarded as a skeletal crystal (Hopper-crystal). Skeletal crystal growth is considered to be the basis of morphogenesis in the single-crystal test of Patellina.
