- Diagnosis
- Small spheroidal to obovate gyrogonites with flat summits and broadly to narrowly rounded bases. They range from 350^ to 400/x, in length and 300/* to 350/* in width with maximum diameter at or slightly above midheight. Gyrogonite surface fairly smooth; spirals consist of broadly rounded cellular furrows separated by low intercellular ridges. Calcification of spirals reduced on summit area where they become more deeply concave and then turn upward to form small peaked projection in center. Twelve to thirteen spiral ridges visible in a lateral view.
