We report results from the second in a series of follow-up nebular abundance studies of emission-line galaxies found in the KPNO International Spectroscopic Survey (KISS). Galaxies with 12 + log(0/H) ≲ 8.2 (estimated from the coarse empirical method for calculating metal abundances described in Melbourne & Salzer (2002)) were selected for observation with the MMT Blue Channel Spectrograph. Spectra of 14 galaxies, which cover the full optical region from [OII]λ λ 3727,3729 to beyond [SII]λ λ 6717,6731, are presented, and abundance ratios of N, O, Ne, S, and Ar have been computed. Oxygen abundances determined through the direct electron temperature (Te) method confirm that all of the galaxies are metal-poor with 7.61 ≤ 12 + log(O/H) ≤ 8.32. By using these abundances in conjunction with other Te-based measurements from the literature, we demonstrate that the star-forming dwarf galaxies in KISS, along with the more specific class of Blue Compact Dwarfs (BCDs), follow the same metallicity-luminosity relationship as ones which have been previously determined for dwarf irregular (dIrr) galaxies.
