Answer:
NGC 5236 aka M83 and the Southern Pinwheel Galaxy is a barred pinwheel type galaxy. NGC 4151 is categorized as a Seyfert type galaxy.
Explanation:
Barred spiral galaxies such as NGC 5236 generally have a elongated center that is called a bar. From that bar are arms that spiral. The arms are composed of star and stellar material. The spaces in-between hold much less stellar matter.
Seyfert type galaxies, such as NGC 4151, are generally characterized by a core that is bright, compact, and is not shaped like a bar. This type of galaxy generally has spiral arms as well.
