Terebellum fusiforme Lamarck —de Gregorio 1890, p. 116, pl. 10, figs. 7, 8. Type material. Holotype — USNM 495948 . The type measures 31.4 mm in length, with a width of 9.5 mm . Type locality. Brooksville , Hernando Co. , FL , USA [Rupelian] . Diagnosis. The shell is moderately slender. The labrum is not thickened. The growth lines are slightly prosocyrt. The columella is bent backward basally. Distribution. MIOCENE— USA Tampa, Florida ( Shimer & Shrock 1944 ). OLIGOCENE— USA Brooksville, Hernando County, Florida ( Jung 1974 ); Alabama ( Vokes & Vokes 1968 ); Georgia ( Vokes & Vokes 1968 ). Remarks. Jung (1974) treated this species as a nomen dubium based on the lack and quality of the material available, known only from the internal casts that form the type series. Notwithstanding the lack of evidence for a posterior canal in the material examined, the shape of the body whorl, particularly the anterior section, differentiate this species from other Seraphs . The shell is similar to S. striatus from the Oligocene of Germany .
