  We have used the instruments on the Spitzer Space Telescope to study the
Large Magellanic Cloud supernova remnants (SNRs) N11L, N44, N49, N206, N63A,
and N157B. The two large SNRs N44 and N206 were not detected in any IRAC or
MIPS wavebands; the remainder were detected at one or more wavelengths. In
particular, the SNRs N49 and N63A each had features that were evident in all
available IRAC and MIPS bands. Each of these two also displayed faint limb
emission in the MIPS 24 micron band only. IRS spectra obtained for the N49 SNR
showed a number of prominent lines, with little continuum contribution. We
therefore suggest that N49, and possibly N63A, are dominated by line emission,
with thermal emission from hot dust being at most a secondary component.
