Dorsally, following a small round initial chamber there are 5 barely discernible chambers in the first whorl; in the second and third whorls there are 2ÃÇÂ_-4 chambers in each whorl, rapidly increasing in size, with the penultimate chamber nearly perpendicular to the last one. Ventrally, there are 3-3ÃÇÂ_ chambers, the penultimate one being elongate, semioval, with a long, straight and deep, perpendicular suture, and leaning against the last, large, semispherical chamber.
