  We have employed time-dependent local-spin density theory to analyze the
multipole spin and charge density excitations recently found in GaAs-AlGaAs
quatum dots [C. Sch\"uller et al, Phys. Rev. Lett {\bf 80}, 2673 (1998)]. The
overall agreement between theory and experiment is good, identifying the
angular momentum of the modes observed in the experiment. We have found that
high multipolarity spin density edge modes originate from interband transitions
instead that from intraband transitions, as it happens in the dipole case.
