NORTH AMERICAN FAUNA 



This publication series includes monographs and other reports of scientific investigations 

 relating to birds, mammals, reptiles, and amphibians, for professional readers. It is a con- 

 tinuation by the Fish and Wildlife Service of the series begun in 1889 by the Division of 

 Ornithology and Mammalogy (Department of Agriculture) and continued by succeeding 

 bureaus — Biological Survey and the Bureau of Sport Fisheries and Wildlife. The Service dis- 

 tributes these reports to official agencies, to libraries, and to researchers in fields related to 

 the Service's work; additional copies may usually be purchased from the Division of Public
