We review the predictions of SU(4) symmetry and the Glashow-Iliopoulos-Maiani mechanism for the semileptonic decays of {1/2}{sup +} charm baryons. We use, wherever possible, the experimental masses of charm baryons; for the unknown masses we use the predictions of mass formulas. The {ital q}{sup 2} dependence of form factors is taken to be either of monopole or of dipole form. For {Delta}{ital S}={Delta}{ital Q}={minus}1 transitions, very large branching ratios are predicted---of the order of 10%.
