    Notes: [Auszug] DAVID Brown is to be congratulated on writing an exceptionally fine treatise on the gastropod fauna of Africa, a reference book which will be set a standard of quality and content for many years. His stated goal of presenting a "comprehensive" account of this subject which will be of value to ...

    Notes: Summary The cuticle of fourth larval stage N. dubius consists of a limiting membrane, outer and inner cortices, matrix, and two fibrous layers. The adult cuticle displays a limiting membrane and outer cortex, but the remainder of the cuticle is not subdivided into discrete layers. The limiting membrane is triple-layered, and its filamentous surface coat binds Thorotrast (pH 2.1). Time sequence studies on the genesis of the limiting membrane indicate that it is a plasmalemma transformed from the cuticle-hypodermis membrane. The cortex and matrix of the adult cuticle form by differentiation of hypodermis cytoplasm subjacent to the cuticle-hypodermis membrane. The fiber layers form under the matrix by intrahypodermal secretion. The cuticle is thus intrahypodermal. The cuticle-hypodermis membrane is discontinuous in fourth larval stage and adult worms, and direct communication is established between the cuticle and hypodermis.

    Fine structure and histochemistry of the parenchyma and uterine egg capsules ofOochoristica anolis (Cestoda: Linstowiidae) (1984)

    Notes: Abstract Gravid proglottids of the linstowiid cestode,Oochoristica anolis, were studied by transmission and scanning electron microscopy and light microscope histochemistry. Primary attention was given to the structure of uterine egg capsules and the medullary parenchyma throughout which they are distributed. Each capsule consists of a syncytial uterine epithelium, with material that appears to be its secretory product deposited in the lumen. Each capsule contains one egg. A basal lamina connects the uterine epithelium to medullary parenchyma cells, each of which is almost completely filled by a single lipid droplet. Parenchyma cells are sarcoplasmic extensions of medullary myocytons and possess a glycogen-rich cytoplasm. The overall proglottid structure results in each uterine egg capsule being surrounded completely by lipid-containing cells. This arrangement may facilitate transmission of oncospheres by slowing desiccation outside the host.
