To understand the types of galaxies and identify the odd one out, let's review the characteristics:

1. **Elliptical Galaxies**: These galaxies are smooth and featureless, ranging from nearly spherical (E0) to more elongated shapes (E7). They contain older stars and little interstellar matter.

2. **Irregular Galaxies**: These do not have a distinct regular shape, and their structure is often chaotic. They usually contain many young stars and lots of gas and dust.

3. **Spiral Galaxies**: These galaxies have a flat disk containing stars, gas, and dust, as well as a central bulge of older stars. They are characterized by their spiral arms.

4. **Eccentric**: This term does not refer specifically to a type of galaxy in astronomic classification. Rather, "eccentric" is more commonly used in a variety of contexts such as mathematics (describing curves) or to describe behavior and denotes a lack of conventionality but does not classify a galaxy type.

### Final Answer
The correct choice is **eccentric**, as it is not a recognized type of galaxy.
