Predictions for the semileptonic decays of charm baryons are given in two quark models: The nonrelativistic and the MIT bag models. We find that several processes have large branching ratios, of the order of few percent; these are very large in comparison with the strange-hyperon semileptonic-decay branching ratios. We also notice that the {ital q}{sup 2} dependence overwhelms other corrections and should be considered in the future with more emphasis. Finally, the predictions found for the {Lambda}{sub {ital c}}{sup +} decay---when compared with the corresponding experimental value---leave ample room for the existence of a fourth generation.
