Nina M. Roy has proved (3) that every separable G-space is square, thus exposing an error in my paper (1), in which I proposed a construction of non-square G-spaces which purports to include separable examples. The mistake lies in Lemma 5, whose proof confuses the weak-* topology with the bounded weak-* topology. This note is to salvage the construction to the extent possible, which is in the nonseparable case. The context and notations of (1) are used without further comment.
