The work of Lutz and Kelker (1973) is extended to the case where the sample of stars is limited by apparent magnitude. In order to compute average-absolute-magnitude-difference corrections for a magnitude-limited sample, it is necessary, in general, to adopt a luminosity function. It is shown, however, that for some samples of stars the average-absolute-magnitude-difference corrections of the previous paper apply, independent of the luminosity function. An example is given to show how to determine if this is the case.
