Family Syllidae. It looks as if the antennae and cirri and articulated so subfamily Syllinae. If you can give me close ups of the anterior tract so I can see if there's an internal tooth & it's position, and the setae, I might be able to give you a genus as well. Probably Typosyllis just because there are more species in that genus than all the other genera in that subfamily combined.
