We present an all-sky search for bright, transient emission lines from 300 to 550 keV in more than two years (1993 December and 1996 March) of data from the Burst And Transient Source Experiment (BATSE) on the Compton Gamma-Ray Observatory. Our approach is sensitive only to events with durations from 0.5-3.0 days. The results show that the gamma-ray sky is very "quiet" in these two years, which is consistent with an earlier search using BATSE data from 1991 to 1993. No transients are observed in the search, and our 3 σ upper limits are significantly below the fluxes of the two most significant events previously reported from Nova Muscae and 1E 1740.7-2942 by SIGMA. The disagreement between the BATSE data sets and those of SIGMA are quantitatively discussed.
