The Relation of Mollusks to Fish in Oneida Lake 109 
E. COMPARISON WITH OTHER LAKES AND 
LOCALITIES. 
1. Tomanawxk Lake, Wisconsin. 
The only lake with which the writer is personally 
acquainted that is comparable to Oneida Lake is Tomahawk 
Lake, situated on a line between Oneida and Villas Counties, 
Wisconsin (Baker, 1911a). This lake is over four miles long 
and two miles wide, and its many bays and coves give it a 
shore line of over eighty miles. It is surrounded by heavy 
forests, particularly on the south shore, where there is a virgin 
forest belonging to the Wisconsin Forest Reservation. The 
north and south borders have been extensively logged over. 
A conspicuous subaqueous terrace borders the shore, afford- 
ing excellent habitats for aquatic plants. The small bays 
are usually rather shallow, as are also the areas covering the 
terraces, but in the middle of the lake the depth is reported 
to be as much as 60 feet. 
The mollusean fauna is rich and varied, 47 aquatic species 
being recorded of which 20 are found in Oneida Lake. Three 
varieties, not generally known to inhabit the lakes of New 
York State, are common to both regions. Planorbis binneyi, 
Physa ancillaria warreniana, and Lymnea stagnalis lilliane, 
the latter being first described from Tomahawk Lake. The 
characteristic habitats of Tomahawk Lake are repeated, in a 
degree, in Oneida Lake. 
9. Laker St. Crarr, Micutean-Canapa. 
This lake lies between Lake Huron on the north and Lake 
Erie on the south (Smith, 1894, pp. 43-44). The lake has 
an area of 410 square miles, a shore line of 187 miles, and a 
depth of about 20 feet in the center. There is a great develop- 
ment of shallow water along the shores and hence a large 
quantity of vegetation, which supports a large and varied 
fauna. 
An extensive mollusean fauna occurs consisting of 45 
species. Seventeen species of this number are found in
