Foreword 



THE STUDIES presented in this volume have been made over a period 

 of years on various aspects of the lives of Amphibia in Oklahoma. 

 They were produced under the auspices of the University of Okla- 

 homa Biological Survey, on whose staff most of the authors represented 

 serve. It is the hope of the Survey and of the individual contributors that 

 these collected studies may afford useful information in a form which 

 will prove convenient to students of this branch of scientific investiga- 

 tion in Oklahoma.
