SHELL: Thin to robust, regularly ovate-conic in outline; perios- 
tracum yellowish-horn color; surface generally polished, semi-trans- 
parent, growth lines very fine, crossed by a few inconspicuous spiral 
lines ; the last whorl is malleated in some specimens ; whorls 5%, rather 
regularly and rapidly increasing in size, flatly rounded, the body whorl 
usually convex; spire turreted, broadly-acutely conical, about as long 
as the aperture; nuclear whorls 114, the second whorl very wide and 
low, resembling in outline that of Galba jacksonensis; sutures well 
impressed; aperture ovate or roundly-ovate, broadly and evenly 
rounded below, narrowed and angulated above; outer lip thin; inner 
lip triangular, reflected and rolled over into the umbilical region, leav- 
ing a very small chink; parietal callus very thin.
