A search for the decays {ital K}{sub {ital L}}{sup 0}{r arrow}{mu}e and {ital K}{sub {ital L}}{sup 0}{r arrow}ee has produced no examples of either process. When normalized to the decay {ital K}{sub {ital L}}{sup 0}{r arrow}{pi}{sup +}{pi}{sup {minus}}, the 90%-C.L. upper limits on the branching ratios are {ital B}({ital K}{sub {ital L}}{sup 0}{r arrow}{mu}e){lt}2.2{times}10{sup {minus}10} and {ital B}({ital K}{sub {ital L}}{sup 0}{r arrow}ee){lt}3.2{times}10{sup {minus}10}.
