A search for an exotic baryon resonance with S = -2, Q = -2 has -been performed in quasireal photoproduction on a deuterium target through the decay channel Ξ-π- → pπ-π -π-. No evidence for a previously reported Ξ (1860) resonance is found in the Ξ-π - invariant mass spectrum. An upper limit for the photoproduction cross section of 2.1 nb is found at the 90% confidence level. The photoproduction cross section for the Ξ0(1530) is found to be between 9 and 24 nb.
