Diagnosis

|---|---|---|
| W. Blow 1967 | The highly trochospirally coiled test consists of about 11 chambers arranged so that there are three chambers in the last whorl, four chambers in the penultimate whorl and three chambers (at least) in the initial coil about the proloculus; three distinct whorls of chambers are therefore present. The chambers are subglobular, inflated and only comparatively slightly embracing. No primary aperture visible externally, but sutural apertures present in the spiral suture which circumscribes the 3 chambers of the final whorl. Sutural apertures present in the dorso-ventrally direceted intercameral suture between the ultimate and penultimate chambers. Probably only two small sutural apertures also present in the intercameral suture of the penultimate and antepenultimate chambers. No sutural apertures present in any of the intercameral sutures prior to that of the antepenultimate chamber. The very small sutural apertures present in the spiral suture prior to that part circumscribing the last three chambers of the test appear to be entirely at the confluence of the intercameral and spiral sutures. These earlier dorsal spiral apertures are very few in number and probably only two are present prior to that part of the spiral suture circumscribing the final whorl. The wall is calcareous, radial hyaline [62a], thin and delicate, very finely perforate but with the pores widely scattered. The wall bears very small pustules and the pores open between them. Maximum diameter of the holotype 0.42 mm. |
