to the collectors named sets of duplicates of the different 

 species. , 



All of the collections made in this survey are to be 

 kept at the author's laboratory at Charleston, Illinois, till 

 after the report on the work is finished, when they will 

 be sent to the Museum of Zoology at Ann Arbor, Michi- 

 gan, where the collections belonging to the Michigan 

 Geological and Biological Survey are kept. 



Little can be given in the way of results in this paper 

 for not half of the collections have yet been looked over, 

 and more field work is still to be done, and much more 

 literature is yet to be examined. It seems very likely 

 that important contributions to our knowledge of the 

 ecology of Michigan fish will come from the investiga- 

 tions, and probably we will know considerably more 

 about their distribution, habits and life-histories. The 

 work should give results of value to fish culturists and 

 others interested in conserving fish life, for most of the 

 facts obtained should be of economic value, although 

 many of them will not be immediately applicable in fur- 

 thering the welfare of Man.
