Résumé
This paper is a study on microscopic anatomy of the digestive tube in three species of the genus Syllis Savigny, 1818 (S. arnica Quatrefages, 1865; 5. gracilis Grube, 1840; 5. armillaris Muller, 1771) (Polychaeta: Syllidae: Syllinae). The main differentiations of these apparatus -pharynx, proventricle, ventricle, gastric caeca and intestine-are compared. Taxonomic and phylogenetic value of these aspects are discussed in base to their variability.
