Seraphs (Seraphs) sp. Jung, 1974, pl. 5, figs. 1, 2.
Type material. We designate Leymerie 1846, p. 33, pl. XVI, no. 9 as the lectotype. The lectotype measures 58 mm in length, with a width of 20 mm (Leymerie 1846).
Type locality. Montagne Noire, Carcassonne, France [Eocene].
Diagnosis. The shell is smooth and ovate. The spire is moderately high and blunted. The columella is straight, and the aperture is narrow.
Distribution. EOCENE— Pakistan Bhagothoro Hill, Sind, Laki Beds (Jung 1974); Zinda Pir (Jung 1974). Republic of Georgia Akhaltsikhe (Jung 1974). Iran Transcaspia or northern Persia (Eames 1952). Spain (Eames 1952). Switzerland (Eames 1952). Italy (Eames 1952). France (Eames 1952). Bartonian/Lutetian— Armenia (Eames 1952). Bartonian— Italy (Eames 1952). Lutetian— France (Eames 1952). Italy The Bavarian Alps and Bahrein Island (Eames 1952). Ypresian— France (Eames 1952). PALEOCENE—Thanetian— France Carcassonne (Jung 1974).
Remarks. One of the earliest Seraphs, arising during the Thanetian, S. carcasense is the current candidate to link the Palaeocene west African S. minus and the later Seraphs radiations complex during the Eocene. While sharing similarities with S. sopitus, a species with which it has been synonymised (Jung 1974), the fossil records indicate that S. carcasense precedes that species, which arose in the Ypresian.
