Original Description: From Dall, 1890 (p. 31):“Later Eocene of Vicksburg, Mississippi; Pliocene of the Caloosahatchie beds. When fully developed this species is about an inch long, with 12 to 14 sharp-edged ribs on the last whorl, a faintly internally lirate outer lip, and about a dozen rather prominent spiral threads with much finer spiral striae in the wide interspaces; the most characteristic feature is the double oblique rippling of a narrow band in front of the suture as it passes over the ribs of the preceding whorl. It seems to be rare in the Caloosahatchie beds, and is not known in a recent state. It is one of the most ancient representatives of the ostrearum type.”
