The heat capacity of the cubic Ce_xLa_<1-x>Pd_3 ternary alloys have been measured in the temperature range 1.5 to 10 K. The alloys consist of single phases except in the region 0.3<x<0.5. These measurements supplement earlier measurements on the electrical resistivity on these alloys which had revealed the Kondo side-band effect. The specific heats for the compositions x=1.0 and 0.8 were found to obey the equation C_P=γT+βT^3 with a high value for γ. The heat capacities for the remaining compositions showed marked deviations from this simple relation, and exhibited well-defined minima in the C_P/T versus T^2 curves in some cases. These deviations were attributed to the influence of paramagnons. The significance of these results are discussed in terms of a model for the electronic structure of these alloys.
