Using data recorded by the CLEO III detector at the Cornell electron storage ring (CESR), we have made measurements of some properties of the {sigma}{sub c}*{sup ++} and {sigma}{sub c}*{sup 0} charmed baryons. In particular: {gamma}({sigma}{sub c}*{sup ++})=14.4{sub -1.5}{sup +1.6}{+-}1.4 MeV, M({sigma}{sub c}*{sup ++})-M({lambda}{sub c}{sup +})=231.5{+-}0.4{+-}0.3 MeV, {gamma}({sigma}{sub c}*{sup 0})=16.6{sub -1.7}{sup +1.9}{+-}1.4 MeV,M({sigma}{sub c}*{sup 0})-M({lambda}{sub c}{sup +})=231.4{+-}0.5{+-}0.3 MeV.
