Original Description

Für eine kleine Radiolarie, die im Bau sich an Psilomelissa anschließt, aber eigenartig in der Gestalt des Kopfes abweicht, sei hier eine neue Gattung errichtet. Schale bestehend aus Kopf und Thorax. Kopf glatt ohne Horn, deutlich abgesetzt vom Thorax, welcher in der Nackengegend drei seitlich abstehende Stacheln trägt. Kopf durch eine Einschnürung von oben nach unten in zwei Teile geteilt, die aber zusammenhängen, daher ""bilokular"". Die Nackengegend von sekundärem Gitterwerk überzogen, welches vom oberen Teil des Thorax zum unteren Teil des Kopfes zieht und dadurch teilweise die Kopf-Brust-Einschnürung verdeckt.


Translation:
A new genus has been designated for a small Radiolaria, that has the same structure as Psilomelissa but mostly differs by the shape of the cephalis. This genus may be characterized as follows. Shell with a cephalis and a thorax. Cephalis smooth, no horn, well differentiated from the thorax, which bears three laterally directed spines in the collar area. Cephalis separated into two parts by a vertical stricture, resulting in a ""bilocular"" structure. From the upper part of the thorax to the lower part of the cephalis, the collar area is covered by a secondary meshwork, that partially masks the stricture between the cephalis and the thorax . (In German. Translated by J.P.C.)]
