Total fusion cross sections ${\sigma }_F$ have been measured for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$+${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ in the energy range $24<\mathrm{}{E}_{\mathrm{c}.\mathrm{m}.\mathrm{}}<42\mathrm{}$ MeV using the $\Delta E-E$ technique. The excitation function of ${\sigma }_F$ shows only two structures at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}=29\mathrm{} \mathrm{and} 38$ MeV which seem of different origin than those observed in the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$+${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ system. The saturation value of the measured fusion cross section agrees with that obtained for other systems with nucleons in the $s-d$ shell.
