Description: Distinguished by the characteristic compact shape with a lipped, umbilically situated aperture, coarsely perforate wall and tendency for the final chamber to protrude beyond the earlier ones.
Comparison: This species occurs in its most typical form in tropical faunas. New Zealand populations tend to be more compactly chambered.
Distribution: Waiauan to Opoitian (Hoskins, 1978).
Comment: Waiauan to Opoitian (Hoskins, 1978). Present throughout most of the Opoitian. Rare specimens in the Whakapunake limestone (upper Opoitian) are possibly reworked.
