R. J. Foley, M. Papenkova, D. Weisz, A. V. Filippenko, and R. Chornock, University of California, Berkeley, report that inspection of CCD spectra (range 310-1000 nm), obtained on Apr. 8 UT with the Shane 3-m telescope at Lick Observatory, reveals that SN 2003cr (IAUC 8103) is probably of type Ic, within a few weeks past maximum brightness. SN 2003da (IAUC 8108) is of type II shortly after the explosion; the very blue continuum is nearly featureless, but low-contrast hydrogen Balmer lines and weak He I 587.6-nm are visible and have P-Cyg profiles. SN 2003db (IAUC 8108) is also of type II, probably a few weeks after the explosion. The broad H_alpha emission line is much stronger than the absorption component.
