INTRODUCTORY NOTE
It is hoped that this third volume of "The Abbey Nature Books" will be no less popular than the preceding volumes devoted to British Mammals and British Birds. A feature of this third book in the series is that practically every species included is illustrated, and these illustrations, together with the descriptive matter, will, it is hoped, result in more attention being paid to these classes of animals than heretofore. The Author has to acknowledge his indebtedness to Mr. Frank Gibson's "Superstitions about Animals," and to Mr. C. Tate Regan's admirable book on "The Fresh-Water Fishes of the British Isles," to which the reader is confidently referred for more detailed information concerning the third class of animals included in this volume.
