Opis

Water-dwelling relatives of the earthworm were the subject of an international symposium in Baton Rouge, Louisiana, in March 1988, where these 26 papers were presented. They were also published in Hydrobiologia volume 180 (1989). Contributors from Europe, North America, and Argentina consider a wide
