Synopsis

A detailed reference on land snails, richly illustrated and rich with descriptions of multiple species. The text focuses on shell form, surface sculpture, color patterns, and opening features to aid identification. It also provides measurements and notes on variation, with cross‑references to figures for visual comparison.

This edition presents a range of species in the Helix‑Solaropsis group, including detailed remarks on umbilicus, spire height, whorl shape, and the extent of markings. You’ll also find notes on geographic provenance and the historical names associated with each shell.

- Clear diagnostic details you can use to tell closely related shells apart (texture, color, banding, and sutures).
- Descriptions of variations within a species, including forms that are pale or differently marked.
- References to accompanying plates and figures that show the shells from multiple angles.
- Geographic notes that link shell forms to regions like the Amazon Basin, Jamaica, Surinam, Brazil, and Ecuador.

Ideal for readers who collect shells, study mollusks, or simply enjoy the science and beauty of these shells.
