We discuss VLA 1465 MHz images of the Galactic SNRs G9.8+0.6, G11.4-0.1, G12.0-0.1, G24.7-0.6, G344.7-0.1, G346.6-0.2, G351.2+0.1, G352.7-0.1, and G355.9-2.5. The current study, performed at a sensitivity of about 3 mJy/beam and an angular resolution of about 40 arcsec, enabled us to recognize new features, to reclassify the morphological type of several remnants, and to estimate the parameters of these SNRs. Our observations have revealed that in the majority of cases the shells retain circular symmetry, even when most of the objects included in the sample are likely to be evolving into a complex environment. Three out of the nine observed objects (G11.4-0.1, G344.7-0.1, and G351.2+0.1) exhibit characteristics of 'composite' morphology (a shell plus centrally concentrated emission). Polarization distributions at 1465 MHz were determined in the direction of G344.7-0.1, G346.6-0.2, G351.2+0.1, G352.7-0.1, and G355.9-2.5. Only the SNR G355.9-2.5 shows significant linearly polarized emission.
