Pseudococculinidae

The shells are small (less than 6 mm), thin and translucent. The protoconch shows a long, narrow apical fold. Its microscopic sculpture is smooth with fine threads. The asymmetrical radula shows a broad, rachidian tooth that lacks a cusp, four inner lateral teeth, a large pluricuspid tooth, and numerous marginal teeth. Soft body: the right tentacle is generally modified into a copulatory organ. == Genera ==
