Circumbilical ridges interpreted as the loci of a pair of retractor muscles are described on two internal moulds of M egalomphala taenia, a characteristic bellerophontacean from the Silurian of Gotland, Sweden. Comparison with muscle scars in other bellerophontaceans confirms an assignment to the Gastro- poda.
