EXTRACT FROM THE PREFACE. 



The kind reception given to my little book on the ' Common Shells of California 

 has induced me to prepare this large work, embracing a wider territory, namely, that part of the 

 United States lying west of the Rocky Mountains. The present volume includes descriptions of 

 all the bpecies mentioned in the former one, and also treats of many.of the uncommon and minute 

 shells which are found along the coast, from Alaska on the north, to Mexico on the south. It 

 also describes the land and fresh-water moilusks of California, Oregon, Washington, Idaho, 

 Utah, and Nevada ; thus making it of use as a reference book for the interior, as well as along 

 the sea-coast. 



The nearly two hundred engravings have all been drawn from nature, expressly for this 

 work, and while materially increasing its cost, they will, 1 trust, even more increase its value. 



To adapt the book to younger students, it is written in a simple 

 STYLE, the NAMES of the species are explained and the pronunciation 



is INDICATED. 



A Key for the Analysis of Shells, and a Biographical Index of Natur- 

 alists are new and helpful features; 



There is also a Glossary for beginners, and a carefully prepared 

 Check List for collectors. 



It is most desirable that the children and youth of our Western Slope should become 

 interested in and intelligently acquainted with the rich and varied forms of life which are 

 resting or moving all around them. Hence it is hoped that this book will be placed in all 

 school libraries, and. where practicable, be used for supplemental reading by the older classes. 

 At the sea side, many pick up and admire a few shells without knowing anything of their 

 aames or nature. By the aid of this book such aimless shell gathering may happily be changed 

 into a source of intelligent and elevating pleasure. 



For COLLECTORS in other parts of this country and abroad, this book will be found of especial 

 valae, both in making up lists of desiderata and studying and arranging their exchanges. 



The Frontispiece is a hand-painted engraving of the very rare and beautiful Surcula Carpen- 

 terianana, Gabb. 



The book contains upwards of two hundred and thirty pages, and is carefully printed on 

 fine, heavy paper, and neatly bound in cloth. 



Price, Postage Paid, $1.75, net.
