>I guess the addition of a new family is in order for my database.  I've done a few searches on the Internet for Seraphidae and found three Web sites, but none include a list of species other than Terebellum.  Are there any modern reference(s) available that list all of the species included in the Family Seraphidae?<

I believe Terebellum terebellum is the only living species.  I do not know of a modern revision of worldwide fossil species.  It is also a relict in its distribution, as fossil species occur in the Caribbean and Florida.
