In [1] we constructed a family of nontrivial topological s-cobordisms of 3dimensional quatemionic spaces. This and further considerations led to the result that there are either 2 2r~~r~~1 or 2 2r-r distinct s-cobordisms of any quatemionic space-form M r = S 3 /Q r to itself, where Q r denotes the quaternion group of order 2 r+2 . In [2] we erroneously claimed, using in part various exact sequences in algebraic L-theory, that the upper bound was precise, and used this to detect the topological
