- Oogonia large, broadly obovoid to almost spherical, 1.08 mm. to 1.35 mm. in length and 1.06 mm. to 1.31 mm. in width. Summit truncate, the spirals narrowing and becoming abruptly flattened at the summit periphery, then widening and remaining flat or becoming slightly swollen near the point of junction in the center of the summit, many specimens distinctly coronulate. Spirals on most specimens gently convex, on a few flattened or slightly concave, eight or nine (rarely seven or 10) visible in lateral view, no evidence of tubercles. Base strongly projecting on most specimens.
