The gamma ray spectrum from p-barp annihilation at rest has been measured with good energy resolution and high statistics using a magnetic pair spectrometer. We find no narrow lines with widths comparable to the resolution. We obtain upper limits (90% C.L.) on the yield of narrow baryonium states of 2--5 x 10/sup -4//p-bar for states below 1700 MeV, and 5--10 x 10/sup -4//p-bar for states between 1700 and 1800 MeV.
