PREFACE.

In offering to the public their work on the " Genera of Keeent Mollusca," the Authors believe they are supplying a want in this branch of Zoology, especially as active research is now being made into the structure and habits of the animals that produce the beautiful shells so much admired in the cabinets of Conchologists.

They have endeavoured, as far as the present state of knowledge on this subject would permit them, to group the Genera in accordance with their natural affinities, and they trust that, from the care with which they have consulted every original source of information, the work will prove a correct and useful guide to those who desire to become better acquainted with this interesting division of the animal kingdom.

The Authors desire to acknowledge their obligations to Dr. Gray, Mr. S. P. Woodward, and especially to Mr. Hugh Cuming, who, with his accustomed love of science, has afforded them liberal access to his unrivalled collection, and freely imparted to them much valuable information relative to the habits and localities of various genera.

With regard to the illustrations, the Authors may add, that many are derived from drawings of the living animals,
