Histochemical analysis of oligochaete body wallThe body wall muscle fibers of . and . have been hystochemically characterized. The results have been compared with similar data on . and .. The various enzymatic activities have been correlated with the ultrastructural data and a possible functional meaning of the different muscle layers has been proposed.

Body wall organization in enchytraeidsheir circular muscles, whereas longitudinal muscles show significant differences, allowing an easy identification of the various worm species. In particular, differences are noticeable in the external longitudinal layer. These observations suggest that structural and ultrastructural muscle fiber organizations can be used as a taxonomic tool.

T-system in muscles of microdrilesisternae, membrane foldings and extracellular spaces between fibers is described. The data seem to indicate that the spaces between fibers within each functional unit are interpretable as T-tubules of a cross-striated fiber.

Discovery of ., a lumbriculid that is clearly convergent with . in terms of the pharynx, lends further support to this concep
