DEAR SiR: The following report, which I have the honor to submit to you, contains 
descriptions of all the fishes known to inhabit the waters of the State of Ohio, with

States National Museum, for the privilege of examining the various collections made in 
Ohio by Professors Baird, Putnam, Milner, and others, and preserved in the National 
Museum. To Professors Theodore Gill and E. D. Cope, I am indebted for various useful 
suggestions, and to Dr. John Sloan, Mr. J. H. Klippart and others, for specimens of rare 
fishes. I am also indebied to my former colleague, the late Professor H. HE. Copeland,
