With this size it has 64 septa in six cycles (S12&gt;S3&gt;S4&gt;S5), with S1S4 complete and 16 S5 placed principally in half-systems adjacent to the principal septa, close to the protosepta, with their development accelerated. From them, only S1 and S2 reach the columella merging with it. S1S2 are subequal in length, S3 slightly shorter, and the S4 reach into the middle of S3; S5 are rudimentary. Some specimens are almost circular in lateral view (fig. 5C).
