EDITOR’S PREFACE. 
The only change which has been made in Lhe present volume of 
the Becord is the introduction of a section devoted to General 
Subjects. This includes text-boolcs and works of a general nature, 
which it has been thought advisable to record in this way. Many 
of these books and papers are again recorded under the several 
groups with which they are more especially concerned. 
The list of Zoological Periodicals has been revised and enlarged. 
I am indebted to Dr. G. H. Fowler and to Mr. W. L. Sclater for 
help in this work. I also desire to express my thanks to Mr. B. B. 
Woodward, of the General Library, Natural History Museum, for 
much kind assistance. 
FRANK E. BEDDARD.
