We compute the magnetic moments of charmed baryons using the gauge-theory quark model of De Rujula, Georgi, and Glashow. We find that these moments are quite different (sometimes differing in sign as well as magnitude) from those computed by Choudhury and Joshi, who used U(8) symmetry. The reason for the difference is that in our calculation the heavy mass of the charmed quark badly breaks U(8) symmetry. Our results reduce essentially to those of Choudhury and Joshi when all quark masses are set equal to one another. (AIP)
