Combined UV and optical spectra are presented for the Fe II Seyfert galaxy Akn 120. The galaxy shows unusually strong Ly-alpha and UV Fe II emission, as well as a jump in the continuum at 3000-4000 A. The spectra are obtained with the IUE satellite telescope in both the short and long wavelength regions. Also discussed is an optical spectrum which has been taken nearly simulataneously with the UV spectra, thereby avoiding the effects of a possible variability of Akn 120.
