Multiplicity fluctuations in rings around the jet axis and in off-axis cane
s have been measured by the DELPHI collaboration in e(+)e(-) annihilations
into hadrons at LEP energies. The measurements are compared with analytical
perturbative QCD calculations for the corresponding multiparton system, us
ing the concept of Local Parton Hadron Duality. Some qualitative features a
re confirmed by the data but substantial quantitative deviations are observ
