Vol. 75, no. 2

art. no. e46

The type, figured and cited material of thirteen species assigned by van Hoepen (1942, 1946) to his genus Ophryoceras, a synonym of Pervinquieria (Pervinquieria) Böhm, 1910, are described and illustrated, and shown to be a single variable Late Albian ammonite species. Pervinquieria salebrosa van Hoepen, 1942 is a further synonym. Van Hoepen (1946) referred a series of fragments to Ophryoceras sp. under four separate entries. We have not seen this material which we refer to as ?Ophryoceras spp. (a)–(d); they may be further synonyms of salebrosa.
