We present a spectroscopic analysis of Eridanus IV (Eri IV) and Centaurus I (Cen I), two
ultrafaint dwarf galaxies of the Milky Way. Using IMACS/Magellan spectroscopy, we identify
28 member stars of Eri IV and 34 member stars of Cen I. For Eri IV, we measure a systemic
velocity of ${v} _ {\mathrm {sys}}=-{31.5} _ {-1.2}^{+ 1.3}\\mathrm {km}\,{{\rm {s}}}^{-1} $
