Original Description
Die drei kugeligen Gitterschalen verhalten sich wie 1: 3: 7 an Grösse. Die Rindenschale rauh von kleinen Stacheln, die runden Gittermaschen 1/15 ihres Durchmessers gross, mit gleich grossen Zwischenbalken. Drei grosse Stacheln, die sich in der Art einander gegenüber stehen, dass ein dreikantiger fast 3/5 des durchmessers der Rindenschale grosser, zwei eben so gestalteten aber kleineren gegenüber steht.
[Radial proportions of the three globular shells 1: 3: 7. Cortical shell rough with small spines, circular pores 1/15 as large as the diameter of the shell, with bars of same size. Three big spines, one pair distributed in front of the other one, three-sided, nearly longer than 3/5 of the diameter of the cortical shell, the pair similar but smaller in length. (Translation from German by J.P.C.)]

Diameter of the cortical shell 100µm, pores 10µm. Diameter of the median shell 33µm, medullary shell 12µm. Length of the big spine 57µm, basal width 20µm, length of the two small spines 20µm, width 15µm.
Very rare, one single specimen.
