Measurements of the deHaas-vanAlphen effect were performed in the intermetallic compounds URh$sub 3$ and UIr$sub 3$. Complex spectra were observed in both materials. Effective mass measurements were made for several orbits in URh$sub 3$ and values as large as 5.3 m$sub 0$ were observed. The relatively complete data in URh$sub 3$ are consistent with a complex multiply-connected Fermi surface which is in qualitative agreement with band structure calculations. The largest frequency branches in UIr$sub 3$ appear to have the same topology as their corresponding branches in URh$sub 3$. In addition, a number of closed low- mass surfaces exist in UIr$sub 3$ and are discussed in terms of the calculations for URh$sub 3$. (auth)
