We report three spectroscopic classifications using near-infrared spectra (range 800-2400 nm) obtained with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope. Classifications were done comparing the near-infrared spectra to the library of Marion et al. 2009, A.J. 138, 727. LSQ13ry was supplied by the La Silla-Quest survey (see Hadjiyska et al., ATel #3812). It was discovered on 2013-03-30 at RA=10:32:48.00, DEC=+04 11 51.75 at 19.3 mag. All redshifts are from the presumed hosts and approximately match the supernova redshifts.
