We report the discovery and spectroscopic classification of 18 new supernovae from PTF (ATel #1964; http://www.astro.caltech.edu/ptf ). The supernovae were discovered by Oarical, an autonomous software framework of the PTF collaboration, as well as by Galaxy Zoo Supernovae (arXiv:1011.2199), based on observations made with the Palomar 48-inch Oschin Schmidt telescope. Spectroscopy was undertaken with the R-C spectrograph mounted at the Cassegrain focus of the Mayall 4-m telescope at the Kitt Peak National Observatory on UT 2010 November 2-4. The superfit (Howell et al. 2005, ApJ 634, 1190) and SNID (Blondin & Tonry, 2007, ApJ 666, 1024) programs were used for classification. Details of the discoveries are as follows:
