Description: Length up to 23 mm for 45 segments. Live specimens yellowish transparent ( Fig. 6 View Figure 6 ), ventrally on posterior segments often with broad, dark longitudinal band. A few notochaetae usually present

from about segment 12 ( Fig. 7E View Figure 7 ). In all other features agreeing with the description of N. punctata   above.

Remarks: The description and illustrations above are based on Swedish specimens, as these were in much better condition than the type material and could also be studied alive and by SEM. They agree both with the types from the Middle Atlantic Bight and a newly collected topotype, and, based on COI analyses by Nygren et al. (2005) and this study, the types and the Swedish populations are conspecific.
