Using the CLEO-II detector, we have obtained evidence for a new meson
decaying to $D^0 K^+$. Its mass is $2573.2^{+1.7}_{-1.6}\pm 0.8\pm 0.5$
{}~MeV/$c^2$ and its width is $16^{+5}_{-4}\pm 3$~MeV/$c^2$. Although we do not
establish its spin and parity, the new meson is consistent with predictions for
an $L=1$, $S=1$, $J_P=2^+$ charmed strange state.
