Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. L. Titus 2000 | (emended from Horn and others, 1989). Glaphyritids with at least the first 5-6 post-nuclear whorls ophioconic, moderately evolute, very widely umbilicate, and typically, but not always, ornamented by irregular nodes. Suture critical to diagnosis, and by 10 mm D ventral lobe is relatively wide and has a slightly constricted base. Single, sharply defined, high-relief spiral chord absent from umbilical shoulder, which instead bears multiple fine lirae or is smooth. |
