We report the following spectroscopic classification of two supernovae based on observations with the Wide Field Spectrograph (WiFeS - Dopita et al., 2007, ApSS, 310, 255) on the ANU 2.3m telescope at Siding Spring Observatory, NSW Australia, using the B3000/R3000 gratings (3500-9800 A, 1 A resolution). Targets were discovered by the Catalina Real-time Transient Survey (http://crts.caltech.edu/), Stan Howerton, and the Italian Supernova Search Project (ISSP - Simone Leonini, L.M. Tinjaca Ramirez, G. Guerrini and P. Rosi). Classifications were done using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

(1) Good match to SN 1994I at +3 days and SN 1991 N at max. Consistent with redshift of apparent host IC 553 (z=0.022; Huchra et al., 2012, ApJS, 199, 26).

(2) Best match with SN 1992H at 44 days. Consistent with redshift of apparent host PGC 50171 (z=0.028; Da Costa et al., 1998, AJ, 116, 1).
