It is proved that the $n$-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} $n$-twistor description of a massive particle in four-dimensional Minkowski space fails for the case $n\ge3$.
