How to Identify Tegulidae

Key Identification Features

• The upper whorls project slightly outward, and feature plicate, tuberculate, or undulating texture along the sutures; these folds and tubercles become indistinct on the lower whorls.
• The base of the shell is flat, marked with concentric smooth, wide lirae separated by shallow grooves; these lirae become indistinct toward the outer margin.
• These folds may be well-defined, barely visible, continuous, or cut into granules by similarly close spiral furrows; spiral furrowing is sometimes the dominant feature of the surface.
• The columella is short, curved, and distinctly two-toothed near the base.
