The temperature dependent magnetic susceptibility, specific heat, and electrical resistivity were measured on PrInA${mathrm{g}}_{2}$. A broad peak, which is identified as a Kondo anomaly, is observed in the specific heat at $ensuremath{sim}0.4mathrm{K}$ with a strongly enhanced linear contribution at lower temperatures. PrInA${mathrm{g}}_{2}$ is a Pr-based heavy-fermion compound and has one of the largest known Sommerfeld coefficients of $ensuremath{sim}6.5mathrm{J}/mathrm{mol}{mathrm{K}}^{2}$. A new type of nonmagnetic interaction between the conduction electrons and the non-Kramers doublet ground state of the ${mathrm{Pr}}^{3+}$ ion may be responsible for this behavior. Related features are also observed in the susceptibility and resistivity.
