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