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.
