World Polychaeta Database (WPolyDb). McIntosh is commenting on an article by Perrier, in which Polygordius villoti Perrier, 1875 is described. McIntosh comments that Perrier's and his own species are ".. very closely allied, if not identical ..." and he gives TS figure of his Linotrypane and an Ammotrypane. He doesn't say so, but he appears to be maintaining his Linotrypane as an opheliid.
