Shell dextral, umboniiform, with 2 ½ fairly quickly widening whorls. Spire low, flatly rounded with shallow suture lines between whorls. Protoconch consisting of around 1 ¼ whorls, seemingly smooth. Teleoconch whorls wide, weakly convex adapically, becoming increasingly more convex laterally; midwhorl with slight angle on which upper side a narrow, slightly raised and gently convex selenizone is found; abapical whorl ramp short and straight, distinguished from lower midwhorl by strong angle. Selenizone partly covered by adapical wall of succeeding whorl. Base convex, with central narrow umbilicus. Aperture oblique, rounded.

Number of spiral threads above selenizone approximately 27 on last whorl. Base covered by evenly spaced, fine, unbeaded spiral threads spaced much farther from each other than on apical side of whorl; number of spiral threads at least 16 on second whorl, increasing with growth. Growth lines nearly effaced, slightly opisthocyrt while strongly opisthocline.</paragraph>
