We discuss the main rare radiative decays of the strange [ital B][sub [ital s]] mesons, [ital B][sub [ital s]][r arrow][phi][gamma] and [ital B][sub [ital s]][r arrow][ital K][sup *][gamma]. $B sub s -[gt] phi gamma--- is the dominant mode, expected at a branching ratio of (0.3--0.5)[times]10[sup [minus]4]. The calculation of these exclusive channels with two different approaches emphasizes an uncertainty in the prediction of about 2--3. Additional modes are [ital B][sub [ital s]][r arrow][phi][ital e][sup +][ital e[minus]], [ital B][sub [ital s]][r arrow][phi][mu][sup +][mu][sup [minus]] at the 10[sup [minus]6] level and [ital B][sub [ital s]][r arrow]([eta],[eta][prime])[ital e][sup +][ital e[minus]], [ital B][sub [ital s]][r arrow]([eta],[eta][prime])[mu][sup +][mu][sup [minus]] at the 10[sup [minus]7] level.
