  Recently the LHCb collaboration has observed a new pentaquark state, the
$P_c(4337)^+$. Owing to its proximity to the $\chi_{c0}(1S) p$, $\bar{D}^*
\Lambda_c$, $\bar{D} \Sigma_c$ and $\bar{D} \Sigma_c^*$ thresholds, this new
pentaquark might very well be a meson-baryon bound state. However its spin and
parity have not been determined yet and none of the previous possibilities can
be ruled out. We briefly explore a few of these options and the consequences
they entail in the present manuscript: (i) the $P_c(4337)^+$ might be a
$\chi_{c0}(1S) p$ bound state, (ii) the $P_c(4312)^+$ and $P_c(4337)^+$ might
be $\bar{D}^* \Lambda_c$ and $\bar{D} \Sigma_c$ states close to threshold,
respectively, where the Breit-Wigner mass might not correspond to the location
of the poles, (iii) the locations of the $P_c(4312)^+$ and $P_c(4337)^+$ might
be explained in terms of the $\bar{D}^* \Lambda_c$-$\bar{D} \Sigma_c$ and
$\bar{D}^* \Lambda_c$-$\bar{D} \Sigma_c^*$ coupled channel dynamics. This last
option, though not the most probable explanation, is still potentially
compatible with the double peak solution of the $P_{cs}(4459)^0$ and with what
we know of the $P_c(4312)^+$. As a byproduct of the previous explorations, we
conjecture the existence of a series of anticharmed meson - antitriplet charmed
baryon bound states and calculate their masses.
