XVI INTRODUCTION 



The last part of this book is devoted to a geographical index 

 arranged alphabetically. By turning to a certain group of 

 islands, the reader can see at a glance what species of animals 

 inhabit that group. 



The illustrations of the various mammals were drawn by 

 George F. Mason of the American Museum of Natural History. 

 Several of the figures showing teeth and limbs are the work of 

 Miss Janet Roemhild ; the map was done by Miss D. F. Levett 

 Bradley. It was based, with the exception of the insert of the 

 Aleutian Islands, upon a projection prepared by the American 

 Geographical Society, New York, 1942. 



The authors wish to express their deep sense of gratitude to 

 two members of the staff of the American Museum of Natural 

 History — Dr. H. E. Anthony, Chairman of the Department of 

 Mammals, and Mr. Childs Frick — for their unfailing interest 

 and valued advice during the preparation of this book.
