In this paper we study complete orientable surfaces with a constant principal curvature R in the 3‐dimensional hyperbolic space H 3 . We prove that if R 2 > 1, such a surface is totally umbilical or umbilically free and it can be described in terms of a complete regular curve in H 3 . When R 2 ≤ 1, we show that this result is not true any more by means of several examples. This contradicts a previous statement by Zhisheng [6]. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
