Optical and radio data that reveal the peculiar morphologies of four IRAS galaxies are discussed. NGC 1620 is shown to have an off-center arclike structure of 3 kpc radius that may be the largest supernova-blown bubble known. UGC 2982 is an ongoing merger of two gas-rich galaxies. It is shown that the UGC 3004/3005 pair is not interacting despite the proximity of its components. UGC 3004 is a regular barred spiral galaxy. A second nucleus in the edge-on system UGC 3005 suggests a recent merger. Finally, IRAS 23385 + 0300 is one of the most infrared-luminous galaxies known. 23 refs.
