Type material. Holotype — NMB H14347. The type measures 71.8 mm in length with a width of 16.4 mm ( Jung 1974).

Type locality. Yellow Limestone Group , Jamaica [Lutetian] .

Diagnosis. The shell is elongated and has a moderately acute apex. The spire has three to four whorls and is slightly dorso-ventrally convex. The columella is slightly twisted at the base.

Distribution. EOCENE—Priabonian— Panama Gatuncillo Formation ( Woodring 1959; Jung 1974; Tripati & Zachos 2002). Jamaica Claremont Formation of Claremont, St.Ann ( Jung 1974). USA Florida Crystal River Formation, Taylor County ( Jung 1974). Lesser Antilles St Bartholomew Formation of St Bartholomew Island ( Jung 1974). Trinidad Boca de Serpiente formation ( Rutsch 1939). Lutetian/Bartonian— Jamaica Yellow Limestone Group ( Jung 1974). Haiti Plaisance Limestone ( Jung 1974). Spain Santa Maria Formation Manresa, Barcelona Province ( Jung 1974).

Remarks. Known from internal casts and poor quality material, the taxon is variable in the slenderness and angle of the spire ( Jung 1974).
