In this habitat, the large number of Prsidia present is note- 
worthy. The abundance of small mollusks and the large num- 
ber of species of this group (18) shows this habitat to be a 
good feeding ground for bottom feeding fish, such as pump- 
kinseed and suckers s, as well as turtles.

The Shepard Point region is not characterized by a sharp 
projection of land, as is the case with other localities called 
“Points ” but is a fairly uniform, rounded area about a mile 
or less in length. The banks here are very steep and bluff- 
like, rising some 20 feet above the level of the lake. A sandy, 
gravelly or bouldery beach lies at the foot of this bluff (Fig. 
ti). 
Borrom: Very bouldery. Warrer: Gradually deepen- 
ing from 6 inches to 4 feet. 
VEGETATION. 
Water Willow (Dianthera ameri- Lake Bulrush (Scirpus occiden- 
cana). talis) . 
The Bulrush society borders the lakeward side of the Water 
Willow society. Animal life was here abundant, as noted 
below, the clams living in the sand between the rocks and 
the snails on the rocks or vegetation.
