INTRODUCTION

In pursuance of the plan of zoological exploration which the
Museum of Vertebrate Zoology, since its inception, has had under way
in northwestern North America, a field trip was made into that region
during the summer of 1921. The expenses of this trip, as of the
preceding ones, were defrayed by Miss Annie M. Alexander, whose
interest in the zoology of the northwest was the determining factor in
directing the activities of the Museum toward that part of North
America. The locality chosen for the 1921 expedition was the valley
of the upper Skeena River, northern British Columbia, centering at
the town of Hazelton. Our party consisted of two, the writer and one
assistant, Mr. William Duncan Strong, a student at the University of
California. The material collected consists of 265 mammals, 687 birds,
and 50 reptiles and amphibians.

Acknowledgments are due to several institutions and individuals
for aid, both in prosecution of the field work and in the subsequent

studies of the material collected. From the Dominion Parks Branch,
Department of the Interior, Canada, and from the Game Conservation
Board of British Columbia, Vancouver, permission was received to
