Patellogastropoda and Vetigastropoda.- Some localities of the gastropod bearing St-Ursanne Formation are presented herein. Described in detail are the locations La Caquerelle and Rieji near Roggenburg. All in all could be found 32 species from Patellogastropoda and Vetigastropoda. New are the genera Oxfordina n. gen., Helvetataphrus n. gen. and Pseudangaria n. gen. as well as the species Patella staceata n. sp., Emarginula rara n. sp., Rimulopsis torulosus n. sp., Chilodonta tricostatula n. sp. and Cochleochilus? spiralocostatus n. sp.
