GENERAL LIST OF MOLLUSCA. 



In the following lists there has been no serious attempt to classify the 

 shells of the state in any systematic manner. At the present time geo- 

 graphical distribution is the most important feature. In pursuance of this 

 object, the arrangement is chiefly alphabetical. Only in a few instances 

 have data which give exact localities been attainable. In seeking to en- 

 large the list hereafter only specimens accompanied with exact locality 

 references should be admitted. 



A number of shells listed from Indiana in various amateur papers, and 

 known to belong to a fauna entirely different, have been excluded as not 

 being authentic. No injustice is done any student by relegating these 

 forms to a doubtful list and awaiting the result of careful examination 

 within the state. Should such examination reveal the forms so excluded 

 it will be a source of congratulation that so many extralimital shells should 

 be found in Indiana.
