Graham - I suspect you meant to write NOTE the two ridges.
This would indicate that it is P.lamarcki (renamed Spirobranchus lamarcki WoRMS).
Spirobranchus triqueter is descibed in Hayward & Ryland quite specifically as having ONE median ridge.
So, I guess you might need to change the ID - I'll agree then.

no I did...

...actually mean it hasn't got 2 ridges - poorly written - I guess, Derek, it would have been better to put note: single ridge.

OK I agree with this one Graham; it's strongly triangular suggesting Spirobranchus triqueter
Interestingly there is utter confusion in a few of the books I have. I am really trying to make a definitive post of triqueter but cannot find lararcki to compare!
good wishes then..
Now see
