BIBLIOGRAPHY. 
The following list of references to North American Lymnezas 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:
