AbstractFerrero, E. (Istituto di Biologia Generale, Universith di Pisa, Pisa, Italy.) A fine structural analysis of the statocyst in Turbellaria Acoela. Zool. Scr. 2 (1): 5–16, 1973.—The fine structure of the statocyst components in the acoelan Convoluta psammophila is described, namely: capsule, parietal cells, lithocyte, and the statolith. The absence of ciliary structures, the highly developed endoplasmic reticulum of the lithocyte and the layered texture of the statolith are remarkable. A functional interpretation of the muscles inserted on the statocyst and of the nerve bundle running nearby is suggested. The morphological similarities and differences between the acoelan statocyst and the statocyst of lower and higher invertebrate phyla are discus
