A. V. Filippenko, R. J. Foley, and M. Ganeshalingam, University of California, Berkeley, report that inspection of CCD spectra (range 330-1000 nm), obtained on Aug. 16 UT with the Shane 3-m reflector at Lick Observatory, reveals that both SN 2004df (IAUC 8374) and SN 2004dp (IAUC 8383) are of type II (probably II-P, about 2 months after the explosion, based on the well- developed P-Cyg H_alpha profiles). SN 2004di (IAUC 8376) is of type Ia; specifically, its spectrum closely resembles that of the peculiar, subluminous SN 1991bg (Filippenko et al. 1992, A.J. 104, 1543) about 3 weeks past maximum brightness. SN 2004dv (IAUC 8388) is of type II, many months past maximum brightness; it is well into the nebular phase. SN 2004ds (IAUC 8386) is of type II; the well- developed P-Cyg hydrogen Balmer-line profiles suggest a type II-P subclassification, and an age of roughly 1 month after the explosion.
