As far as I know, Pectinaria gouldii is an eastern North American species
and not (yet) present in European waters. The tube you photographed is not
complete, which makes it a bit difficult to identify without the worm,
although a person routinely identifying European species could probably do
so.
Strangely enough, none of the faunas treating European pectinariids show the
tubes (e.g., Hartmann-Schroeder 1996 (or 1971) Tierwelt Deutschland 58;
Hayward & Ryland 1996: Handbook of the Marine Fauna of North-West Europe;
Holthe 1986: MIOS vol. 7 on Polychaeta Terebellomorpha; Kirkegaard 1996:
Danmarks Fauna vol. 86 [sedentary polychaetes}; or Wollebaek 1912:
Nordeuropaeiske Annulata Polychaeta. I. Ammocharidae, Amphictenidae
[with
photos, but none of pectinariid tubes, or at most a fragment of one].
Jean Vovelle has done some work on Pectinaria koreni. For a photo with tubes
of all four common northern European species, see Vovelle 1971; for photos
of details of tubes (and juveniles) of P. koreni, see Vovell 1973.
Vovelle, J. 1971. Sélection des grains du tube chez les Amphictenidae
(polychètes sédentaires). Cah. Biol. Mar. 12: 365-380. [see plate 1 (p.
373)]
Vovelle, J. 1973. Evolution de la taille des grains du tube arénacé en
function de la croissance ches Pectinaria (Lagis) koreni Malmgren (polychète
sédentaire). Ophelia 10 (2): 169-184 (for photos of VERY small tubes see p.
179 – the scale bars are all = 200 µm).
Without the narrow end of the tube it is difficult to decide how much it is
curved. My guess is that you either have P. koreni or maybe P. auricoma.
For maldanids, Arwidsson 1912: [Scandinavian maldanids] has good photos of
the worms and detailed drawings of the chaetae, but no figures of the tubes.

Hello Kirk,
I am not an expert, but am a biochemist. I do study Pectinaria gouldii
cement and genetics (collaboratively). The tubes do look similar to those
that we have collected from the New England (USA) coastal area. Have you
seen the worms? That would tell the tale. I can send you some pictures we
have taken if you are interested.
Cheers,
Maria

Dear Polychaete experts.
I am new to the annelida mailing list and new to marine polychaete research.
I am looking for local tube builders to study here in Denmark. I have the
attached photo of some tubes and I am interested if any of you know what
types of organisms built them.
I figure that the conical, regular shaped shells must come from Pectinaria
but which species? gouldii?
the second tubes are more irregular. They could be Maldanids. They have very
strong glue component.
both tube types were found washed ashore on Skane; the northernmost tip of
Jutland in Demark last year.
Is this enough information to give a likely genus for the irregular tube and
a likely species for the Pectinaria?
kind regards
