Common Names
Members of this genus are commonly known as "Top Snails" due to their conical shape. However, specific common names may vary depending on the species.
Characteristics

- Conical Shell: The shell is generally conical in shape with a pointed apex.
- Solid and Heavy: The shell is sturdy and heavy, often with a thick, smooth outer layer.
- Spiral Sculpture: The shell surface exhibits spiral ridges or cords, which can vary in prominence depending on the species.
- Coloration: Coloration can range from shades of brown, gray, or white, often with intricate patterns or markings.
- Operculum: The operculum, a hard, plate-like structure that closes the opening of the shell, is present and usually made of calcareous material.
Environments
