The gill-bearing region of the body is flattened dorsally and rounded ventrally and the limits of the segments are clearly marked. Behind this region the body is cylindrical and the limits of the segments are almost impossible to distinguish. From the distance apart of the chaetal bundles it can be seen that the segments are about twice as long as in the anterior region. The posterior region of the body looks much more like a fragment of some microdrilid Oligochaete, such as Nais, than part of a Polychaete.
