We have undertaken a near-IR spectral survey of stars associated with compactnebulae recently revealed by the Spitzer and WISE imaging surveys. Thesecircumstellar nebulae, produced by massive evolved stars, display a variety ofsymmetries and shapes and are often only evident at mid-IR wavelengths. Starsassociated with ~50 of these nebulae have been observed. We also obtainedrecent spectra of previously confirmed (known) luminous blue variables (LBVs)and candidate LBVs (cLBVs). The spectral similarity of the stars observed whencompared directly to known LBVs and Wolf-Rayet (WR) stars indicate many arenewly identified cLBVs, with a few being newly discovered WR stars, mostly ofWN8-9h spectral type. These results suggest that a large population ofpreviously unidentified cLBVs and related transitional stars reside in theGalaxy and confirm that circumstellar nebulae are inherent to most (c)LBVs.
