Remarks.—In our opinion, the diagnostic differences between Mathildidae and Gordenellidae as outlined by Gründel (2000) remain valid despite Guzhov’s (2007) doubts. Gordenellids differ from mathildids in the rather large size, slender to very slender shape, high number of whorls, early teleoconch whorls with mathildid ornament (three primary spiral ribs, middle and abapical spiral strongest and angulating whorl profile, numerous opisthocyrt axial ribs), and change of the ornament on mature teleoconch whorls (sometimes complete reduction) (see below).
