Shell globose with rapidly expanding whorls; spire elevated: sutures not deeply impressed: aperture suboval to subrounded; thin inductura on parietal lip; ornament of short, prosocline lirae extending from suture on upper whorl surface; rest of surface smooth except for faint growth lines: apical angle 101 to 109 degrees.
