Optical spectra, JHK photometry, and B and R band CCD observations of a sample of galaxies very luminous in the infrared have been obtained from the IRAS minisurvey and analyzed. The optical spectra are consistent with photoionization by hot stars in a dusty medium. The JHK colors are consistent with a reddened normal stellar population or a stellar population with a power law continuum component. The far-IR luminosities are consistent with other luminous starburst galaxies. A large population of optically dull galaxies with only very weak emission or nonexistent emission lines is found. It is concluded that the vast majority of the studied galaxies are probably the result of a starbust in a dusty medium.
