We report a revised classification of SN 2007nm (Palomar-QUEST transient PQT 071008:224527+103932, Drake et al. ATEL#1234) based on additional spectroscopy beyond that reported by Djorgovski et al. (ATEL#1240). Using spectra obtained by the SuperNova Integral Field Spectrograph on the 2.2-meter University of Hawaii Telescope, the Nearby Supernova Factory has observed that strong a Si II 6355 feature has not developed, and that the spectrum is more similar to that of a Type Ic supernova at an approximate redshift of z = 0.04.
