Type material. Holotype — USNM 135098 . The holotype type measures 50.6 mm in length, and has a maximum width of 18.5 mm . Type locality. Near Port Antonio , Portland Parish , Jamaica [Priabonian] . Diagnosis. The shell is convolute and moderately inflated and similar to Seraphs sopita Brander, 1766 . The teleoconch is blunt with a blunt apex. The volutions of the shell are smooth. The aperture is elongated and narrow. The labrum is not marginated and the peristome is sharp. Distribution. EOCENE—Priabonian— Jamaica Port Antonio ( Jung 1974 ). Remarks. Jung (1974) noted the significance of this material as being the only example of Seraphs from the Caribbean and placed it provisionally within the S. sopitus complex. Seraphs carcasense shows similarity in form to the new species, and while that species is known from Europe and Asia, it is not currently recorded from the Americas, with Seraphs kaindraperi n. sp. representing a direct descendant of the S. carcasense complex. Seraphs sopitus from the Eocene of Europe is also similar to the new species but is slender and more constricted anteriorly. We chose to recognise this material based on its unique geological positioning, and do not consider the limited quality or quantity of material a barrier to its recognition; the lack of material is a not too uncommon feature of the Seraphsidae .
