Excerpt from A Guide to the Shell and Starfish Galleries: Mollusca, Polyzoa, Brachiopoda, Tunicata, Echinoderma, and Worms, Department of Zoology, British Museum (Natural History), Cromwell Road, London, S. W
One of the large north galleries approached from the Bird Gallery is devoted to the exhibition of the extensive Glass of Mollusca. Specimens of the types of all the principal divisions of this Class are exhibited, either entire and preserved in spirit, or as models. However, as not the animals, but their shells have always been a favourite object of study, and a popular source of pleasure to collectors, the exhibition of the species of shells has been made as complete as the space of this Gallery admitted. It has thus proved adequate for the requirements of the majority of visitors and students who consult this Collection. A separate series of British Shells is exhibited in some small table-cases along the west wall.
This Gallery also contains the exhibited series of Polyzoa, Brachiopoda, and Tunicata.

Paperback. Zustand: New. Print on Demand. This book is a comprehensive guide to the extensive glass of Mollusca, an animal phylum including well-known examples such as octopuses, snails, and clams. Molluscs are soft-bodied, cold-blooded creatures whose circulatory, respiratory, and central nervous systems are more developed than those of worms but less developed than those of vertebrates. They have a radulaâ"a tongue-like organ featuring numerous teethâ"and most species feature a hard outer shell. The majority of Mollusca are marine animals, but the book also includes species that live in freshwater and land-based habitats. The book is divided into sections focusing on anatomy, evolution, and taxonomy, and discusses some of the fascinating phenomena associated with Mollusca such as the formation of pearls and the ability of certain species to glow. This detailed and well-illustrated book is a valuable reference for biologists, particularly malacologists, and those with a general interest in the natural world. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
