A PROPOSED CENSUS OF MICHIGAN MOLLUSCA. 



BY BRYANT WALKER. 



At the Annual Meeting of the Michigan Academy of Science in 

 December, 1895, a suggestion was made that the conchologists of 

 the State should form a " Section of Couchology " for the purpose 

 of united work in that department. 



A circular of inquiry elicited such favorable responses, that in the 

 spring of the following year a temporary organization was effected 

 with a membership of fourteen as noticed in the NAUTILUS for 

 April, 1896. At the present time the membership includes every 

 active collector in the State so far as known. Practical work being 

 the object of the Section, it was decided, as a preliminary step to the 

 complete knowledge of the fauna of the State, to undertake the com- 

 pilation of all the known localities for every species known, or sup- 

 posed to belong to it. A form of blank was prepared for distribu- 

 tion upon which the individual reports should be made, and another 

 upon which these reports should be tabulated. A special map of 

 the State has also been printed showing the principal river and 

 lake systems upon which it is proposed to spread these tabulated
