Radio continuum observation of the cluster of galaxies A1367 obtained at 1.4 GHz with the very large array (VLA) in various configurations are combined in this work to produce a radio map of the central region of the cluster with an rms noise of 0.13 mJy. Using a digitized plate of the region on which all spiral+Irr galaxies with B less than 18.0 are selected, we find that 19 radio sources are identified with late-type galaxies, 9 of which were previously unknown. By determining the frequency distribution of the radio/optical and radio/IR ratio of galaxies in A1367 we confirm previous claims that spiral galaxies with a high radio/optical ratio in this cluster are approximately equals 10 times more frequent than in a reference sample of 'field' galaxies of similar morphological type and similar distance.
