LIFE HISTORY OF DESMOGNATHUS FUSCA. 329 



is not too difficult for the inexperienced beginner, and may even 

 yield important contributions to our general knowledge. 



It is with the hope, therefore, that these pages will be useful 

 and suggestive to those interested in any amphibian problems 

 upon which the study of Desmognathus might have some bearing, 

 that it has seemed worth while to collate the known facts con- 

 cerning the life history of this common and interesting species.
