Type material. Holotype — USNM 135097 A. The type measures 56.9 mm in length and 11.6 mm in width ( Maxwell et al. 2018a ). Type locality. White Limestone Group , Port Antonio , Jamaica [Priabonian] . Diagnosis. The shell is very slender with slightly concave whorls. There is a distinctive elongation of the shell on later whorls. The base of the shell is anteriorly quadrate. The shell spire is acute. Distribution. EOCENE—Priabonian— Jamaica Port Antonio ( Jung 1974 ). Remarks. Paraseraphs cantamessae is comprised of eight specimens , which are internal casts. The shape of P. cantamessae is much narrower than the larger and more dorso-ventrally convex P. procerus ( Merian, 1844 ) , which shares a similar geological record. P. cantamessae is similar to other Paraseraphs from Europe, and particularly to P. armoricensis ( Cossmann, 1897 ) , and was likened to that taxon by Jung (1974) , but occurs after that species disappears during the Bartonian. Paraseraphs canatemessae is similar also to P. propedistortus ( de Gregorio, 1880 ) , being slender with an acute spire, but the latter is restricted to the Lutetian of the Mediterranean.
