A search for the lepton-family-number-violating decays {tau}{r_arrow}e{gamma} and {tau}{r_arrow}{mu}{gamma} has been performed using CLEO II data. No evidence of a signal has been found and the corresponding upper limits are B({tau}{r_arrow}e{gamma}){lt}2.7{times}10{sup {minus}6} and B({tau}{r_arrow}{mu}{gamma}){lt}3.0{times}10{sup {minus}6} at 90{percent} C.L. {copyright} {ital 1997} {ital The American Physical Society}
