Mr. Gray,

Your specimen possesses a proventriculus so is therefore family Syllidae.
Smooth tentacular cirri and basally fused palps (at least as far as I 
can tell) so is therefore subfamily Eusyllinae
Straight pharynx armed with a single tooth...

Therefore, based on your pictures you have, I believe, either:

 1. genus Pionosyllis
 2. genus Eusyllis

Without close-ups of setae and details of rim of pharynx I think that's 
as far as I can go.
Others connected with this mailing group will certainly be able to give 
you more precise identification than I can (and double-check my 
suggestions) but that should be a starting direction for your researches.

All the best,

Mr. Bryn Villers
