PUBLICATIONS RECEIVED. 
LAKE MAKINKUCKEE, A PHysICAL AND BIOLOGICAL SURVEY. 
By Barton Warren Evermann and Howard Walton Clark. 2 
Vols. Publication No. 7, Department of Conservation, State 
of Indiana, Indianapolis, 1920. The mollusks are treated on 
pages 41 to 75 of Vol. 11 of this, the most exhaustive work on 
the ecology of any body of water in the United States. Very 
full and valuable notes are given on the food habits and general 
biology of the 14 species of Unionidz which are recorded. The 
remainder of the list, furnished in part by Dr. Paul Bartsch, 
contains 79 species and subspecies of freshwater bivalves and 
univalves and 57 land snails. This brings the total number of 
species and subspecies of mollusks from this small Indiana lake 
and its environs to 180. Such a large number has probably 
not been previously recorded from a similar equal area in the 
same latitude.—G. DaLtLas Hanna.
