BIBLIOGRAPHICAL INDEX. 



This list does uot aim at anything like a complete bibliography. I have 

 merely given references to works or papers to which I bave had occasion to 

 refer in preparing this account of the European Batrachians, which have been 

 alluded to iu the Introduction, or which may prove of use to the reader desirous 

 of making himself more fully acquainted with the subject. Modern contribu- 

 tions, therefore, predominate in this selection ; only standard works among 

 those of older date have found a place in this index. 



Works of purely systematic scope, or descriptive of isolated genera and species, 

 are left out as being sufficiently referred to in the Synonymies heading the 

 account of every species.
