, conical, with 5–5¼ slightly shouldered whorls, punctuated by deep, irregular growth lines; aperture elliptical-ovate to subquadrate; parietal shield compact, positioned low on the body whorl; columella centrally aligned, moderately slender, attenuate; lamella loosely positioned under penultimate whorl succeeded by an incomplete middle lamella and a basal bulge above the umbilicus, forming a thick basal lamella; basal lamella extends out of the aperture as a low ridge on the columellar side of the parietal shield.
with 5 convex shouldered whorls, punctuated by deep irregular growth lines; last half of final whorl coils tightly under penultimate whorl such that right side almost disappears under spire (apical view); aperture elliptical-ovate to subquadrate; peristome narrow on upper palatal side, pronounced notch present at upper junction with parietal shield, columellar side of peristome roundish-angular, callused, rim slightly reflected; rim recedes less than
width of penultimate whorl (aperture facing left view); parietal shield compact, thickly callused with a low straightish edge; columella centrally aligned, slender, attenuate; lamella loosely positioned under penultimate whorl followed by an incomplete weak middle lamella and a lamellar bulge above the umbilicus forming a blunt basal lamella; basal lamella extends out of the aperture as a low ridge on the columellar side of the parietal shield (umbilical view); umbilicus closed, no depression, region callused and puckered; columellar side of peristome callused and positioned straight at center with leftward tendency in relation to the umbilicus; alignment of last ¼ whorl compact.

in that it has a lamella set deep in the shell, which is positioned high up on the columella, but differs in forming a short, very weak parietalis that runs out to less than half of the extension of the parietal shield (umbilical view). The base of the shell (umbilical view) is heavily puckered in
