The similarity of the New York fauna to that of upper Mississippi basin 
as given by Ulrich is shown by the following lists. Of the 108 species identi- 
fied, 68 appear in the Trenton and Black river of the upper Mississippi 
Valley. The collections were made with special reference to the Bryozoan 
fauna, which accounts for the small number of species reported from the 
other classes. It is interesting to note the small number of new species 
found, especially among the Bryozoa, notwithstanding the fact that very lit- 
tle work had been done on that class from collections of the Trenton and 
Black river of New York. <A description of these will be given in a succes- 
sive paper.
