Terebellum fusiforme Lamarck —de Gregorio 1890, p. 116, pl. 10, figs. 9, 10. Type material. Holotype — CAS 434 . The holotype measures 38 mm in length, with a width of 11 mm ( Jung 1974 ). Typelocality. Cowlitz River , Vader, Lewis County , Washington [Rupelian] . Diagnosis. The shell is moderately stout and convolute. The apex is pointed, and there is no evidence of sutures between the volutions. The whorls have protocyrt growth lines. The aperture has a thin labrum and a columella that is basally recurved. Distribution. OLIGOCENE—Rupelian— USA , east bank of the Cowlitz River, near Vader, Lewis County, Washington ( Jung 1974 ); Santa Barbara County, California ( Effinger 1938 ); Griens Ranch Fauna of Western Wash- ington ( Effinger 1938 ). Remarks. Seraphs andersoni is the only member of Seraphs from the north-west American Rupelian. The shape is distinctive in having a more acute apex than other Seraphs . There are two species that proceed S. andersoni from the Priabonian, S. kaindraperi new species from the Caribbean and S. belemnitus from Florida ; both species have a much stouter spire and are less biconic, being more rectangular than S. andersoni . One species of Seraphs proceeds S. andersoni in the Americas, S. hernandoensis from the Chattian and Aquitanian of south-eastern United States ; this differs from S. andersoni in having a much more elongated and narrow form.
