Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Keller and R. Z. Poore 1980 | ion: Test free, globular to subglobular, average size for genus with 2 or 3 whorls of 3 to 3 1/2 spherical to subspherical chambers per whorl. Sutures are distinct and incised. Typical specimen low-spired and have 3 chambers in the ultimate whorl. The umbilical small, circular primary aperture of the ultimate chamber is centered over the suture between the penultimate and antepenultimate chambers (pl. 1, figs. 1,7). The primary aperture of specimens with 3 1/2 chambers in the final whorl, and of some specimens with 3 chambers final whorl, is asymmetrically placed over the suture between penultimate and antepenultimate chambers (pl. 1, fig. 10). Mode high-spired individuals are occasionally encountered (pl. 1, figs. Supplementary apertures are commonly, but not always, present at suture junctions on the spiral side of the ultimate and, less frequently penultimate chambers of the final whorl. Specimens are usually heavily encrusted, so that it is often difficult to tell whether or not supplementary apertures are present. Encrustation similarly masks de of test surface structure, but spine bases, and thus evidence spinose test, are seen on some specimens (pl. 1, fig. 9). |
