We study isometric immersions f : Mn ! Rn+1 into Euclidean space of dimension n + 1 of a complete Riemannian manifold of dimension n on which a compact connected group of intrinsic isometries acts with principal orbits of codimension one. We give a complete classification if either n 3 and Mn is compact or if n 5 and the connected components of the flat part of Mn are bounded. We also provide several sucient conditions for f to be a hypersurface of revolution.
