The magnetic moment of the ..lambda..-hyperon is calculated using the QCD sum rule approach of Ioffe and Smilga. In deriving the sum rules special attention is paid to the strange quark mass dependent terms and to several additional terms not considered in earlier works. These terms are not appropriately incorporated. The sum rule is analyzed using the ratio method. Using the external field induced susceptibilities determined earlier, we find that the calculated value of ..mu../sub ..lambda../ is in agreement with experiment.
