xiv Introduction 
acknowledge indebtedness to all authors, I wish to single out for 
special appreciation the extraordinarily valuable works of G. M. 
Allen, 2 F. N. Chasen, 3 S. I. Ognev, 4 and R. I. Pocock. 5 
The art work has been done under the supervision of the 
Illustration Department of The American Museum of Natural 
History. For the many excellent drawings, some of which were 
made from photographs, I am indebted to the following artists : 
Miss Paula Hutchison, Miss Barbara Kurtz, Miss Dorothy 
Kay, Mr. George F. Mason, Mr. Fred F. Scherer. The three 
maps are the work of Miss D. F. L. Bradley. 
1 am also very grateful to Dr. Lee S. Crandall of the New 
York Zoological Society and to Dr. William M. Mann and Mr. 
Ernest P. Walker of the National Zoological Park, Washing- 
ton, D. C, for sending me the photographs from which certain 
of the drawings were made. 
This volume is a supplemental work in the Pacific Handbook 
Series, prepared under the auspices of the International Com- 
mittee for Wild Life Protection, an organization of persons 
keenly interested in the conservation of wild life in general and 
the protection of many species that are in grave danger of ex- 
tinction in the near future. The committee has, in fact, recently 
published two important books dealing with this very subject, 6 
that should be required reading for every farmer, hunter, sports- 
man, sealer and whaler.
