The low temperature specific heats of C-15 structure UOs2 and UOsIR have been measured in order to compare them with the systems NpOs2, a ferromagnet with T(Curie) = 7.9 K, and NpOsIr, newly discovered to be a spin fluctuation system with a specific heat-gamma of 375 mJ mol-1 K-2. The uranium compounds, with U-U separations of 3.25 angstrom, less than the Hill limit of 3.4 angstrom, show normal metallic behavior, with gamma(UOs2) = 20 +/- 2 mJ mol-1 K-2 and gamma(UOsIr) = 33 +/- 3 mJ mol-1 K-2.
