Type material. Holotype — NHMUK GG21002 . The type measures 35.2 mm in length, with a width of 14.1 mm ( Jung 1974).

Type locality. Rankiot , Sind, Pakistan [Thanetian] .

Diagnosis. The shell is moderately slender with a blunt apex. The teleoconch is moderately high, and consists of three whorls with an indistinct suture and sculpture consisting of weak, closely spaced axial costae that become more developed and more widely interspaced on later whorls. The body whorl has strong axial costae. The lip is thin becoming thicker posteriorly. The posterior sinus forms a canal that extends to the top of the spire and is planar in apical view. The columella is not twisted basally.

Distribution. PALEOCENE—Thanetian— Pakistan Ranikot, Jhirak ( Vredenberg & Cotter 1928); Ranikot, Sind (Cossman & Pissaro 1909; Jung 1974).
