- Diagnosis
- Medium to small subcylindrical to ovoid gyrogonites with fairly small truncate summits; greatest diameter at or below midheight. Distal opening relatively large, occupying greater part of summit, about 100/A in width, somewhat irregular in shape; original filling unknown; basal opening small. Spiral ridges intercellular in position, range from sharp and prominent with deep cellular furrows to inconspicuous with cellular furrows filled to almost the tops of the ridges; cellular furrows 50/*-80ju wide. Eight spiral ridges normal number visible in a side view, about onethird of the specimens with 7 ridges, a few with 9, and occasional small specimens with only 6. Spirals end abruptly at edge of summit opening and do not bend over into central depression.
