We present a summary of results of Compton Gamma-Ray Observatory EGRET observations of the unidentified high-energy gamma-ray sources 2EG J1049-5847 and 2EG J1103-6106. These sources are spatially coincident with the young, energetic radio pulsars PSRs B1046-58 and J1105-6107, respectively. We find evidence for an association between PSR B1046-58 and 2EG J1049-5847. The folded gamma-ray light curve for energies above 400 MeV shows a double-peaked structure whose H statistic implies probability of 0.00012 of being due to chance. Archival ASCA X-ray data, presented by Pivovaroff et al. in a companion presentation, reveal only one source within the gamma-ray 95 circle. This X-ray source is coincident with the pulsar position, lending additional support to the identification of PSR B1046-58 with the gamma-ray source. We find no evidence for gamma-ray pulsations from PSR J1105-6107.
