Description: Distinguished by the fairly large size, thick test and flattened, spreading, moderately biconvex shape, with five to six strongly embracing elongate chambers in the final whorl, a thick peripheral keel and heavily encrusted pustulose early chambers. The aperture is a low arch with a large broad lip.
