ResumoThe fine structure of the syncytial epidermis of Moniliformis dubius (Acanthocephala) was examined with emphasis on the Streifenzone. Numerous crypts elaborate the area of the absorptive surface. Surface architecture is supported by a tripartite filamentous terminal web consisting of a 100 Å sheet underlying the plasma membrane, a more extensive and diffuse inner region surrounding the crypts and a differentiated cytoplasmic annulation encircling each crypt neck. Inclusions and organelles described include filaments, microtubules, glycogen, lipid droplets, vesicles, mitochondria, Golgi complexes, endoplasmic reticulum and five lysosomal types. The eutelic nuclei contain little beterochromatin and have unusual nucleolar features.
