Note(s): The mature male nephridia of Polydora ligni and P. websteri (Polychaeta: Spionidae) are segmental organs composed of a ciliated nephrostome connected to a nephridial canal that crosses the intersegmental septum, expands into a large modified part extending dorsally through the coelom and subsequently narrows into a canal terminating in a dorsal nephridiopore. The nephridial canal is ciliated throughout and is composed of several cell types. Cells in the expanded region of the nephridia of both species contain large urn-shaped depressions filled with long microvilli. In P. ligni, one section of a nephridium contains cells packed with electron-dense granules that are not observed in P. websteri.This manuscript is an author version with the final publicationavailable at http://www.springerlink.com and may be cited as: Rice, S.
