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 Conchology” 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 Nauriius 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, asa 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
