We report the following classifications of optical transients from spectroscopic observations with KOSMOS on the KPNO Mayall 4-m telescope. Targets were supplied by the ATLAS and ASAS-SN. All observations were made on 2016 Dec 01 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
(1) We measure a Si II 6355 velocity of -10,100 km/s.
(2) We measure a Si II 6355 velocity of -11,800 km/s.
(3) We measure a Si II 6355 velocity of -10,700 km/s.
