Diagnosis
ReferenceDiagnosis
Heilprin 1887Shell irregularly oval, obconical, flattened, the flattened ยท appearance being due to three irregular swellings or knobs, one of which immediately adjoins the anteriorly directed fissure of the aperture; aperture narrow, projected forward (in its upper course) a.s a closely compressed fissure, which in a crescential curve ascends to within a comparatively short distance of the apex of the spire; outer lip? (broken in specimen); inner lip largely developed, completely concealing the whorls of the spire, and duplicating for a very considerable extent the outer lip; spire freely in- closed in a pointed superstructure, or dome, built over it by an extension of the mantle; surface covered with lon- gitudinal lines of growth, which extend continuously from the apex to the base.
