We report spectroscopic classification of PSN J08193798-2234147 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). PSN J08193798-2234147 was discovered by Parker on 2014 Sep 28 and observed with WiFeS on 2014 Oct 09. The SN is of Type Ib, with clear He 5686 absorption. Classification with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) shows a good match to SN 1990I at +11 days.
