The Gulellinae and Primigulellinae showcase some of the most beautiful landshells on the planet. What they lack in colour they make up for in their exquisite array of intricate patterns of ribbing and dentition. They are often very small and require keen eyesight to see, and they shelter in discrete places, such as leaf litter in indigenous forests. They are little known, and many species teeter on the brink of extinction. This book is an expression of the author's hope that you will come to be amazed and mesmerised by the subtle beauty of the small and intricate design of the hidden world of nature, and this one special facet of its splendour.
