Abstract
It is proved that the -twistor expression of a particle's four-momentum vector reduces, by a unitary transformation, to the two-twistor expression for a massive particle or the one-twistor expression for a massless particle. Therefore the {\em genuine} -twistor description of a massive particle in four-dimensional Minkowski space fails for the case .
