As Barleeia smithi
Shell broadly ovate, light chestnut brown, with the parietal wall and the inner edge of the columella dark chestnut. Nuclear whorls not differentiated from the rest of the shell. Postnuclear whorls rounded, marked by decidedly retractive linos of growth and exceedingly fine, closely spaced, microscopic spiral striations. Sutures strongly constricted. Periphery of the last whorl inflated, strongly rounded. Base short, strongly rounded, umbilicated, marked like the spire. Aperture subcircular; outer lip thin; columella moderately thick, slightly reflected; parietal wall covered by a thick callus, which renders the peritremc complete.
The type and three other specimens, Cat. No. 227741, U.S.N.M., come from Port Alfred (Coll. No. 836). The type has four whorls and measures: Length, 1.5 mm.; diameter, 0.9 mm.
