Original Description
Die Durchmesser der 3 Gitterkugeln verhalten sich wie 1: 3: 10, und sind sie durch 6 (?) Querbalken mit einander verbunden, die sich nach aussen in 6 starke vierkantige lange Stacheln verlängern, in der Art, dass je 2 sich gegenüberstehende zusammen gehören, und die 6 Stacheln auf 3 um 120° auseinander stehenden grössten Kugelkreisen liegen. Länge der Stacheln ¾ des Durchmessers der Rindenschale.
[Radial proportion of the 3 globular shells 1: 3: 10. Shells linked by 6 (?) radial beams protruding outside as 6 stout four-sided spines, and distributed so that two are exactly on the opposite side, and the six distributed in 3 circular planes at 120°. Length of the spines ¾ of the diameter of the cortical shell. (Translation from German by J.P.C.)]

Diameter of the cortical shell 100µm, pores 10µm, median shell 47µm, medullary shell 16µm. Length of spines 0.07, basal width 0.023.
Very rare.
