Supplementing existing survey data with VLA observations, we have extended γ-ray counterpart identifications down to decl. = -40^∘ using our Figure of Merit approach. We find blazar counterparts for ~ 70% of EGRET sources above decl. = -40^∘ away from the Galaxy. Spectroscopic confirmation is in progress, and spectra for ~ two dozen sources are presented here. We find evidence that increased exposure in the bulge region allowed EGRET to detect relatively faint blazars; a clear excess of non-blazar objects in this region however argues for an additional (new) source class.
