Born-term contributions to the electromagnetic mass splittings of the charmed and uncharmed baryons are estimated using form factors constructed with the help of vector-meson dominance and SU(4) symmetry. The remaining contribution to the mass splittings is assumed to be a tadpole transforming like the third component of isospin. Our results are compared with previous estimates based on the quark model.
