The present Bulletin is the second of a series, which, it 

 is hoped, may be issued from time to time, giving- the results of 

 special work in the laboratories and museum of Oberlin College. 

 The first of the Series was a "Preliminary List of the Flowering 

 and Fern plants of Lorain County," issued in 1889, which, however, 

 did not bear the title of " Bulletin No. i " at the time of its pub- 

 lication. That number, however, will be assigned to it henceforth. 



The present paper is the result of Mr. McCormick's pains 

 taking collection and study of our native fishes, extended through 

 several years, as opportunity has allowed, and resting upon 

 specimens preserved in the museum. It is published in harmony 

 with the conviction, here cherished, that one of the most import- 

 ant duties of any museum is to secure a full representation of the 

 natural objects occuring in its own vicinity, and to make them 

 available to the cause of science. 



Albert A. Wright, 

 May, 1892. Professor of Geology and Naitural History.
