D. C. Leonard, California Institute of Technology, reports that CCD spectra (range 350-900 nm) of SNe 2005mb and 2005me (cf. IAUC 8647), obtained on Dec. 31 UT with the Keck I 10-m telescope (+ LRISp), show them to be type-II supernovae. The spectral features of SN 2005mb are similar to those of SN 1999em (Leonard et al. 2002, PASP, 114, 35) about 4 weeks after explosion; those of SN 2005me resemble the spectral features of SN 1999em about 2-3 weeks after explosion, with the exception that the H-alpha profile is significantly more emission-dominated in SN 2005me. Adopting the NED recession velocity of 7150 km/s for the host galaxy of SN 2005mb (from Fisher et al. 1995, Ap.J. Suppl. 100, 69), the expansion velocity derived from the minimum of the H_beta line is 5000 km/s. Adopting the NED recession velocity of 6726 km/s for the host galaxy of SN 2005me (from Mathewson et al. 1992, Ap.J. Suppl. 81, 413), the expansion velocity derived from H_beta is 7200 km/s.
