The 1.6 µm Near Infrared Camera and Multiobject Spectrometer image of the broad absorption line QSO PG 1700+518 clearly resolves the QSO host galaxy and a ringlike companion. The companion is most likely a ring galaxy produced in a collision with the QSO galaxy ∼5x10⁷ yr ago. The morphology of the PG 1700+518 system is very similar to IRAS 04505-2958 ((ref???)Boyce et al. 1996). Both objects were identified in a sample of eight QSOs selected by ``warm'' far-IR colors and extreme IR luminosities ((ref???)Low et al. 1988). All eight QSOs show signs of strong interaction, and the presence of two head-on colliding systems in this sample may suggest that small impact parameters favor the energizing of IR-luminous QSOs.
