Abstract
We present 1300  $\mu$m continuum emission measurements and observations of the $\element[][12]{CO}$ (1-0) and (2-1) transition towards the centers of 64 Magellanic type galaxies (Sdm/Sm) and irregulars (Im/I0/Irr). The sources are selected to have IRAS flux densities $S_{100~\mu{\rm m}} \ge 1000$ mJy and optical diameters mainly below 180´´. We were able to detect $\element[][12]{CO}$ towards 41 and the continuum emission towards 28 galaxies. In addition, we obtained the corresponding data for a set of 6 complementary galaxies of different morphological type.
