Seraphs belemnitus (Palmer in Richards & Palmer, 1953)

Figure 4B

1953 Terebellum (Seraphs) belemnitum Palmer in Richards & Palmer, p. 25, pl. 3 figs. 9, 12. Jung 1974, p. 25. Woodring 1959, p. 192, pl. 25, fig. 6. = Seraphs (Seraphs) belemnitus Palmer — Jung 1974, p. 25, pl. 6, figs. 11–16.

Type material. Holotype — FGS No. I-7642. The holotype measures 49 mm in length, with a width of 15 mm ( Jung 1974).

Type locality. 4.7 km south of the town of Gulf Hammock , Levy Co., FL, USA, Road metal pit [Priabonian] .

Diagnosis. The shell is convolute and slender. The whorls have rectilinear growth lines. The aperture has a rectilinear labrum margined at the peristome. The labial callus is well developed.

Distribution. EOCENE—Priabonian— USA, Gulf Hammock, Florida ( Jung 1974). Panama Canal Zone, Gatuncillo Formation ( Woodring 1959).

Remarks. Seraphs belemnitus shares the Priabonian with only S. kaindraperi new species from the genus Seraphs of Northern and Central America. Seraphs belemnitus can be distinguished from S. kaindraperi , which is more cylindrical. There are similarities in the slender shape between Seraphs belemnitus and members of Seraphs from Europe and Asia, such as the earlier S. leukoleptus from the Lutetian of France ( Jung 1974), and S. naricus from Pakistan.
