Urosalpinx curtansata

(Original description) The shell is rather thin, biconical, ventricose and oval.

The body whorl is ventricose, gradually attenuated anteriorly into a short blunt siphonal canal.

The spire whorls are ornamented with about six stout, rounded, scaly, spiral ribs, that next but one to the anterior suture a little stouter than the rest, and producing a slight angulation of the whorl.

The inner lip is patulous, slightly arched to the origin of the straight columella, with a thin edge parting the aperture from the umbilical fissure.

[2] Fossils were found in Miocene strata of Victoria, Australia (age range:15.97 to 11.608 Ma).
