BIBLIOGRAPHY. 



The following list of references to North American Lymnaeas is believed 

 to be measurably complete. Absolute completeness cannot be claimed, as it is 

 quite probable that some references have escaped the writer's notice, either 

 because of inaccessible or obscure publication, or of oversight on the part of the 

 author. It is believed, however, that the list includes all of the important 

 references to this subject:
