  We report a new one-parameter family of spherically symmetric, inhomogeneous,
and time-dependent solutions of the vacuum Brans-Dicke field equations which
are conformal to the Roberts scalar field geometries of Einstein gravity. The
new solution is spherical and time-dependent and contains a naked central
singularity. We use it as a seed to generate another two-parameter family of
solutions using a known symmetry of vacuum Brans-Dicke gravity.
