  In the framework of Regge phenomenology, masses of the charmed states
$c\bar{q} (q=u,d,s)$ lying on the $1^3S_1$-like trajectories are estimated. The
overall agreement between our estimated masses and the recent predictions given
by modified quark models[hep-ph/0605019, hep-ph/0608011, hep-ph/0608139] is
good. Masses of the observed charmed states $D_{s0}(2317)$, $D_{sJ}(2860)$ and
$D_{sJ}(2690)$/$D_{sJ}(2700)$ can be reasonably reproduced in the picture of
these charmed states as simple quark-antiquark configurations. We therefore
suggest the $D_{s0}(2317)$ can be identified as the $c\bar{s}(1^3P_0)$ states.
The possible assignments of the $D_{sJ}(2860)$ and $D_{sJ}(2690)$/
$D_{sJ}(2700)$ are discussed.
