Spectroscopy and CCD photometry have been obtained to investigate four galaxies reported to have unusually strong UV excess in their objective prism spectra. The spectra of CG 1293 (B152299+302942) and CG 1331 (B155442+295724) suggest they are Seyfert 1 galaxies, with z = 0.1260\pm0.0002 (standard error) and z = 0.0874\pm0.0009, respectively. H\alpha in CG 1293 has a line width (FWHM) of approximately 4 x 10$^3$ km s$^-1$. The H\alpha, H\beta, and H\gamma lines in CG 1331 have line widths greater than 7 x 10$^3$ km s$^-1$. Spectra for the galaxies CG 1280 (B150126+300206) and CG 1298 (B153025+315554) have no identified emission lines. We find M$_B$=-22.13 for CG 1293 and M$_B$=-22 for CG 1331, for H$_0$=50 km s$^-1$ Mpc$^-1$ and q$_0$=0.5. (SECTION: Quasars and Active Galactic Nuclei)
