  The scotogenic model of radiative neutrino mass with $Z_2$ or $U(1)_D$ dark
matter is shown to accommodate $\Delta(27)$ symmetry naturally. The resulting
neutrino mass matrix is identical to either of two forms, one proposed in 2006,
the other in 2008. These two structures are studied in the context of present
neutrino data, with predictions of $CP$ violation and neutrinoless double beta
decay.
