  The detectability at LEP 200 of explicit $R$-parity breaking by tau-number
$(L_\tau)$ violating operators is considered. The assumption of
$L_\tau$-violation is motivated by the relative lack of constraints on such
couplings but similar considerations apply to explicit $L_e$- or
$L_\mu$-violation. The $LSP$, now unstable, and not necessarily neutral, decays
via $L_\tau$-violating modes. Only signals from the production and decays of
$LSP$ pairs are considered, thereby avoiding any dependence on the sparticle
mass spectrum. Rather spectacular signals are predicted: spherical events with
$m$ leptons (usually containing at least one $\tau$) and $n$ jets $(m,n \leq
4)$, the most characteristic of which are like-sign $\tau\tau$ events. These
signals are enumerated for each $LSP$ candidate and quantitative estimates are
provided for the favoured case when the $LSP$ is a neutralino. Other new
physics signals, which can mimic these signatures, are also briefly discussed.
