Of 90 extragalactic objects chosen from the IRAS catalog on the basis of brightness of 60 microns and warm infrared color, 12 have luminosities characteristic of quasars. These 12 ultraluminous objects have Seyfert spectra, and nine of them show morphological evidence for recent collisions or mergers - they plausibly represent a transition stage between cooler ultraluminous infrared galaxies and optical quasars. 31 references.
