INTRODUCTION 



Rana clamitans , the green frog, is one of the most abundant and 

 widespread ranids in North America. It occurs throughout eastern North 

 America from central Florida to 50° N Latitude in Canada. The literature 

 concerning the species, described in 1801, is vast. With the help of 

 numerous persons, we have attempted to compile a complete bibliography, 

 through 1981, of publications concerning the green frog. We have listed 

 papers and notes containing substantive information about the species, 

 including range records. Papers that only mentioned other references 

 already included are omitted. Although all references have not been 

 checked, we included them if the source were reliable. Many standard 

 field guides and keys for identification that include R^. clamitans 

 appear in the "General" section. 



We searched Zoological Record, Biological Abstracts, Wildlife Review 

 and indices of Copeia, Herpetologica, Journal of Herpetology, the American 

 Midland Naturalist, Herpetological Review and numerous other references. 

 We realize that there are omissions, especially to older papers, locality 

 records, and notes that are not included in standard bibliographic sources. 

 We appreciate obtaining from readers any omitted references which we shall 

 compile as an addendum at a later date. 



Readers looking for topical references should examine all related 

 subject categories since decisions of where to place a particular reference 

 must sometimes be arbitrary. Without becoming too cumbersome, we have 

 cross-referenced other appropriate entries concerning each subject.
