  We present near-infrared spectra for a sample of galaxies with ambiguous
optical emission line ratios. These galaxies fall between starbursts and
Seyferts in the usual optical diagnostic diagrams. We find a similar result
with the near-infrared emission line ratios, which suggests that the galaxies
are composite, containing both a starburst and AGN component. Furthermore, CO
absorption, produced in late-type stars, is detected within the sample,
although at a weaker level than is typical for starburst galaxies. We conclude
that the CO feature is being diluted by a contribution from an AGN, thereby
confirming the composite nature of these galaxies.
