Dear Aaron (and others),
A brief check of your key, only the family Serpulidae, leads me to the
1) it may be useful for local workers. However, just south from your area
(S of Cape Hatteras) the serpulid fauna is a lot more diverse.
2) I would dearly love to see specimens of Filograna implexa. I know that
Hartman 1944 depicts a specimen (Verrill's, from New England and thus
slightly more northern than your area) with the spoonlike membraneous
opercula, but I still wonder whether they occur more southernly. So far I
have only seen non-operculate Salmacina from the E. USA.
3) a linguistical remark: opercula is plural, singular is operculum.
4) the opercular stalk in Hydroides is a modified radiole, not formed by
5) In order to avoid confusion with the probably still to be found but in my
opinion very likely present Ficopomatus enigmaticus* I would suggest
changing 1b. along the following lines: One operculum present, chitinous,
composed of a lower funnel with denticulate margin and an upper funnel
with a crown of spines; on a stalk without barbules, dorsal to about 20
6) 2a. Operculum with some large spines of distal funnel .....
2b. Operculum with all large spines of distal funnel

*8) You would not be the first to mistake a Hydroides for Ficopomatus or
vice versa. For instance Foster's Figs 3, a,b are not Ficopomatus
enigmaticus, but Hydroides elegans. Foster, N., 1972.- Freshwater
