Notes:   1) CSS101012:004005-063616, CSS101019:022415-155112 and MLS101112:010719+175909 appear to be luminous type II-Ps with Mv < -19   based on CSS photometry and spectroscopic redshifts.    2) CSS101115:225640+381044 exhibits prominent P-Cygni H lines similar to SN 2008ax and also resembles the early spectra of SN 1987A.    3) SN 2010kl, discovered by Howerton et al. (2010, CBET#2567) in CRTS SN Hunt data, is found to be a type Ia supernova.    4) SN 2010ji, discovered by CRTS (Drake et al. 2010, CBET#2528), was observed on  2010-11-29UT and found to be a type IIP supernova   approximately 3 weeks past maximum, in  agreement with the event's photometric constraints (cf. Foley et al. 2010, CBET#2581).   5) MLS101113:033911+225352 has a noisy spectrum.    SN were classified using the SNID cross correlation program (Blondin & Tonry, 2007, ApJ 666, 1024).
