Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. H. Easton 1943 | Shell small, involute, discoidal to subglobose in ephebic stages; dimensions of two specimens greatest diameters, 8.2 mm. and 4.9 mm.; greatest widths of body whorls, 8.9 mm. and 5.2 mm. Aperture reniform, width twice length (in the plane of coiling). No prominent geniculation present in shell curvature. Body whorl recurved near umbilical regions, somewhat flared, not revolving. Whorl section acutely lunate posteriorly from aperture. Inner lip seemingly formed by surface of preceding whorl in most cases, without callosity; rare instances of seeming callosities may be result of mineralization. Umbilical regions not excavated, partly enclosed by recurved lateral extremities of body whorl. Surface finely but sharply lirate, about 40 principal lirae with much finer intercalated lirae near edge of aperture; faint transverse growth lines intersect lirae, effect reticulate pattern with concave interstices; fine details most pronounced on the body whorl, which is commonly broken away. About 30 lirations, strongest near plane of coiling, comprise ornamentation of next-tolast whorl. No slit observed, shell not carinate where the slit-band should be located. |
