Various Cretaceous species of Polymorphinidae have irregular Jistulose end-chambers. Similar forms occur from the Jurassic to Recent. The Upper Cretaceous fistulose forms are considered to be abortive offshoots from either the chief smooth species or from the rarer ornamented forms. Their taxonomic significance and occurrence is discussed.
