The Relation of Mollusks to Fish in Oneida Lake 251 
tributary waters which were not collected in 1915. It is 
as here listed, however, a fair-sized fauna, surpassed but 
little, by any other similar body of water in America. As 
no other large lake in the State has been studied in a similar 
manner it is not possible to make direct comparisons. 
1. ANNOTATED LIST oF SPECIES. 
In the following annotated list, reference should be made 
to the large Table No. 18 showing the distribution of each 
species throughout the 41 stations of the lake. Comparison 
is made with several localities in other parts of the country, 
as to ecological relations. As these are quoted throughout 
the list, the page only is given after each reference. These 
are from Wisconsin, Michigan, and Ontario and are found 
in the bibliography under the names of F. C. Baker, Toma- 
hawk Lake, 1911; Walker and Gleason, Isle Royale, 1908; 
H. B. Baker, Saginaw Bay, 1911; and Robertson, Georgian 
Bay, 1915. These several localities are compared on the 
large table at the end of this chapter. The plants known to 
be used as food or for support are given for each species. 
These four lists are chosen because the nomenclature of each 
is modern and the comparison is uniform. The nomencla- 
ture used is the latest by competent malacologists. 
Under each species will be found the names of the plants 
in Oneida Lake which were observed to furnish either food 
or support. The different fish species using each molluscan 
species for food are also given. It is believed that this in- 
formation will be found useful to fish culturists. For the 
benefit of those who may wish to identify the different 
species of mollusks living in the lake, nearly all (57) species 
and varieties are figured on the plates. The local distribu- 
tion in Oneida Lake is shown in the table at the end of this 
chapter.
