Abstract
It is shown that the nonlocally rotationally symmetric Bianchi type-V vacuum solution recently discussed by Nayak is identical, after trivial transformations, with the solution found some years ago by Joseph. In addition some calculations and remarks concerning the integration of the null geodesic equations are given.
