yWe suggest some possible interpretations for the D-SJ(+) (2632) observed by SELEX. The D-SJ(+) (2632) could be the first radial excitation of the I- ground state D-S* (2112), and its unusual decay patten might be hopefully explained by the node structure of the wave functions. In addition, the D-SJ(+) (2632) could also be a c (s) over barg hybrid state or a (cs)(3*)-((s) over bar(s) over bar)(3) (diquark-antidiquark) bound state.
