Original Description
The test is small, conical, the spiral consisting of 3-3.5 whorls. The chambers in the first whorl are small, fitting closely to each other and arranged in a high spiral. The last whorl consists of four chambers, larger and more clearly outlined than the former. The sutures are slightly depressed between the first chambers and more strongly between the last. The aperture is of medium size, umbilical, extending in the last four chambers.

Editors' Notes
Gradstein et al (2017), argue that this species is based on a glauconitic steinkern and so is of no value
